Now the air quality is getting worse, the atmosphere is becoming weaker and weaker, and the ultraviolet rays are becoming stronger and stronger. Ultraviolet rays not only have a certain impact on the skin, but also have the same effect on buildings, especially wooden buildings. So now we have produced a kind of antiseptic wood added with ultraviolet absorber, so as to make the anticorrosive wood engineering construction better.
UV absorbers can be added to preservative wood. A varnish containing UV absorber is being developed to coat the surface of wood or wood products to prevent photodegradation of outdoor wood surfaces. Some use copper, chromium, arsenic and other heavy metal salt preservatives mixed with anti ultraviolet paint to treat wood, which has corrosion resistance and weather resistance.
This kind of ultraviolet absorber uses 2,4-_ The reaction product of hydroxybenzophenone and p-methacrylate epoxy propane ester is painted on the surface of wood. As a transparent protective agent of the surface, it can absorb ultraviolet light, effectively inhibit the light degradation or photodegradation of wood surface, and greatly extend the service life of wood outdoors.
To sum up, antiseptic wood can absorb ultraviolet after adding ultraviolet absorbent, which also shows that antiseptic wood not only strengthens its antiseptic property, but also starts to focus on the prevention of harmful substances in the air.
