Abstract
The invention discloses a weather-resistant PVC (polyvinyl chloride), belonging to the technical field of high-polymer materials. The weather-resistant PVC has excellent weather resistance, can still keep favorable properties under the corrosion of light, cold/heat, rain/wind and bacteria, and has high durability. The antioxidant in the weather-resistant antioxidant can prevent the aging of the PVC and prolong the service life. The ultraviolet absorbent and rare-earth stabilizer can absorb ultraviolet light and emit visible light, thereby effectively avoiding the influence of light. The weather-resistant PVC has low heat conductivity coefficient, can not be greatly influenced by cold and heat, and can not absorb water or be corroded by bacteria. The wood-plastic product prepared from the weather-resistant PVC has excellent weather resistance.
