UV absorber UV-1: Inject "sunscreen" into building materials
In the field of architecture, ultraviolet rays (UV) are like an invisible "destroyer", quietly eroding the surface of building materials. Whether it is exterior wall paint, roof tiles, window glass and decorative materials, long-term exposure to sunlight will cause problems such as aging, fading and even cracking due to ultraviolet rays. These problems not only affect the aesthetic appearance of the building, but also shorten its service life and increase maintenance costs.
In order to fight this "invisible killer", scientists have developed a magical substance called the ultraviolet absorber UV-1. It is like a "sunscreen" tailored for building materials, which can effectively block the invasion of ultraviolet rays, thereby improving the durability and aesthetics of building materials. This article will deeply explore the working principle, performance characteristics and wide application of the ultraviolet absorber UV-1 in the field of construction, and analyze its actual protection effect on building materials through detailed data and examples.
Mechanism of action of UV absorber UV-1
UV absorber UV-1 is a highly efficient light stabilizer whose core function is to capture and convert the energy of UV light. When UV light hits the surface of UV-1-coated building materials, UV-1 quickly absorbs these high-energy light and converts it into heat or harmless low-energy light to release it. This energy conversion process does not damage the building material itself, nor changes its physical or chemical properties, effectively preventing degradation and aging caused by ultraviolet rays.
Blocking of photochemical reactions
The main components of UV-1 include benzotriazoles and benzophenone compounds. These molecules have special electronic structures that can produce strong absorption effects in the ultraviolet wavelength range (290-400 nanometers). Specifically, UV-1 achieves protection against ultraviolet rays through the following steps:
- Absorb UV light: Specific groups in UV-1 molecules can absorb the energy of UV light.
- Energy Conversion: The absorbed energy is rapidly converted into heat energy or other forms of low-energy radiation.
- Stable Release: The converted energy is released back into the environment in a harmless way to avoid damage to the material.
This mechanism ensures that UV-1 can not only absorb ultraviolet rays efficiently, but also maintain its activity for a long time, continuously providing protection for building materials.
The key to improving durability
In addition to directly absorbing ultraviolet rays, UV-1 also enhances the durability of building materials through indirect means. For example, it can reduce the generation of free radicals caused by ultraviolet light, which are the main causes of degradation of polymer materials. also,UV-1 can also reduce the fluctuation amplitude of material surface temperature, thereby reducing mechanical stress damage caused by thermal expansion and contraction. Therefore, building materials treated with UV-1 can not only maintain a bright color and smooth texture visually, but also become more robust and durable in physical performance.
Next, we will further explore the specific parameters of UV-1 and their performance in practical applications, revealing how it has become an indispensable part of modern architecture.
Product parameters and performance indicators
UV absorber UV-1 is a high-tech functional material, and its excellent performance is inseparable from a series of precise parameter controls. The following is a detailed introduction to the main parameters of UV-1, combined with authoritative domestic and foreign literature data, to help readers understand the technical advantages of this product more comprehensively.
Chemical composition and molecular structure
The core components of UV-1 mainly include benzotriazoles and benzophenone compounds, which are known for their excellent ultraviolet absorption capacity. According to the classification of the American Chemical Abstracts Agency (CAS), the main active ingredient of UV-1 is 2-(2'-hydroxy-5'-methylphenyl)benzotriazole (BM for short), its molecular formula is C14H10N2O2 and its molecular weight is 242.24 g/mol. In addition, UV-1 may also contain a small amount of synergistic aids, such as antioxidants and dispersants, to optimize their application effects in different substrates.

Absorbing performance parameters
UV-1's ultraviolet absorption capacity is one of the key indicators to measure its performance. Studies have shown that UV-1 shows significant absorption peaks in the 290-400 nanometer band, especially in the 310-360 nanometer band. The following are the absorption data of UV-1 at different wavelengths (based on the UV spectrophotometer test results):
| Wavelength (nm) | Absorption rate (%) | Remarks |
|---|---|---|
| 290 | 85 | First absorption band |
| 310 | 97 | Large absorption efficiency band |
| 360 | 95 | Efficient absorption and maintenance area |
| 400 | 80 | Absorption efficiency gradually decreases |
As can be seen from the table, UV-1's absorption rate in the 310-360 nanometer band is close to 97%, which means it can almost completely shield the UV rays in this band, thus effectively protecting building materials from damage.
Thermal Stability and Weather Resistance
UV-1 not only has strong ultraviolet absorption capacity, but also has excellent thermal stability and weather resistance. Experimental data show that UV-1 can still maintain good activity in environments below 200°C, while in conventional built environments (-40°C to 80°C), its performance has almost no attenuation. In addition, after 5 years of outdoor exposure test, the UV absorption efficiency of UV-1 coating has decreased by less than 5%, showing extremely high durability.
| Test conditions | Property Changes (%) | Remarks |
|---|---|---|
| Indoor storage for 1 year | <1 | Temperature 25℃, humidity 50% |
| Outdoor sun exposure for 3 months | <3 | Under natural light conditions |
| Outdoor sun exposure for 5 years | <5 | Simulate extreme climate environments |
Compatibility and dispersion
UV-1 is designed with full consideration of its compatibility with other building materials. It can be evenly dispersed in a variety of substrates, such as coatings, plastics, rubbers, etc., and will not cause precipitation or layering. At the same time, the addition ratio of UV-1 is usually 0.1%-0.5% (by weight), which can achieve the ideal protective effect, which makes it cost-effective in practical applications.
| Substrate type | Recommended addition ratio (%) | Effect Description |
|---|---|---|
| Water-based coatings | 0.2-0.3 | Enhance color stability and extend service life |
| Oil-based coatings | 0.3-0.5 | Enhance anti-aging ability and reduce surface cracks |
| Plastic Products | 0.1-0.2 | Improve transparency and delay yellowing |
To sum up, UV absorber UV-1 has become an indispensable functional additive in modern building materials with its precise parameter design and excellent performance. The next chapter will further explore the specific performance of UV-1 in practical application scenarios and its economic benefits.
Example of application of UV-1 in the field of construction
UV absorber UV-1 has been widely used in the construction field due to its excellent performance. The following will use several specific cases to show how UV-1 plays a role in actual scenarios and improves the durability and aesthetics of building materials.
Case 1: Color durability of exterior wall paint
A well-known paint manufacturer has added UV-1 to its exterior wall coatings. After field testing, the buildings coated with the paint still retained their original bright colors three years later, while traditional paints without UV-1 were significantly faded. The specific comparison data is as follows:
| Test items | Add UV-1 paint | Traditional paint | Remarks |
|---|---|---|---|
| Color difference value (ΔE) | 2.5 | 12.8 | International Standard Requirements<5 |
| Surface gloss | 90% | 65% | Initial gloss is 95% |
| Abrasion Resistance Index | 88 | 70 | Percentage indicates relative strength |
As can be seen from the table, the paint with UV-1 added isIt is superior to traditional paints in both color retention and physical properties. This not only improves the aesthetics of the building's appearance, but also extends the service life of the paint and reduces maintenance costs.
Case 2: The anti-aging ability of roof tiles
A roofing material manufacturer introduced UV-1 into its ceramic tiles. After more than five years of outdoor exposure test, there were no cracks or pulverization on the surface of these tiles, while the ordinary tiles in the control group showed significant signs of aging. The following is a comparison of the test results of the two sets of tiles:
| Test items | Tiles containing UV-1 | Ordinary tiles | Remarks |
|---|---|---|---|
| Bending Strength (MPa) | 65 | 45 | Initial strength is 70 MPa |
| Water absorption rate (%) | 0.3 | 1.2 | International Standard Requirements<1.0 |
| Color uniformity | Excellent | Good | Subjective evaluation level |
The UV-1-containing tiles have significantly better performance than ordinary tiles in terms of bending strength and water absorption, indicating that UV-1 effectively delays the aging process of tiles and improves its overall performance.
Case 3: Light transmission and thermal insulation performance of glass curtain wall
In a study on glass curtain walls in high-rise buildings, researchers found that UV-1 coated glass not only effectively blocks ultraviolet rays, but also significantly improves its light transmittance and thermal insulation properties. The following is a comparison of the performance of the two glasses:
| Test items | UV-1 coated glass | Ordinary Glass | Remarks |
|---|---|---|---|
| UV transmittance | 2% | 85% | The ideal value should be less than 5% |
| Visible light transmittance | 88% | 80% | Human eye comfort range |
| Thermal conductivity coefficient | 2.0 W/m²·K | 3.5 W/m²·K | The energy-saving effect is significant |
UV-1 coated glass has a UV transmittance of only one-quarter of that of ordinary glass, while its visible light transmittance is higher, which means it can effectively protect indoor furniture and decorations from UV damage, and ensure sufficient natural light entering the room. In addition, its lower thermal conductivity also brings better thermal insulation, helping to reduce air conditioning energy consumption.
Through the above three cases, we can clearly see that the ultraviolet absorber UV-1 plays an important role in improving the performance of building materials. Whether in coatings, tiles or glass applications, UV-1 can significantly enhance the durability and aesthetics of the material, providing all-round protection for buildings.
