After ultraviolet absorber is handled, surface more uniformly coats ultraviolet absorption material, therefore purple on aeroge surface
The specific surface area of outside line absorbing material further increases, and ultraviolet light is after a large amount of hole walls, gradually by ultraviolet absorber absorption/screen
It covers, reduces influence of the ultraviolet light to coating；
3. surface migration, tridimensional network:
In text message, aeroge density is extremely low, and film forming Shi Yixiang coating surface gradually migrates aggregation, in coating surface shape
At tridimensional network, not only have good ultraviolet absorption ability and ultraviolet shielded ability, also have fabulous heat shielding
Ability, reduces phenomena such as External Heat Flux causes the thermo-oxidative ageing of the excessively high appearance of Coated Surface Temperature, so promoted product because
Jaundice and aging phenomenon caused by high temperature；
4. inorganic filler performance is stablized:
Through overdoping Al2O3After processing, strength of coating after film forming, Al can not only be increased2O3It is steady as inorganic material performance
It is fixed, the reflecting effect (shielding) of coating can be further promoted, influence of the ultraviolet light to coating is reduced, increases the weather-proof of coating
Property.
The technical program compared with the background art, it has the following advantages:
Inventive formulation system can be conducive to improve the weatherability (high temperature resistant, UV resistant lamp) of coating, and guarantee to apply
Layer has excellent adhesive force and shock resistance effect；Wherein modified aerogels, silica solution and nano inorganic filler can be mentioned significantly
Shielding action of the high coating to ultraviolet light and heat radiation inhibits product because aging caused by the environment such as ultraviolet light, high temperature is turned to be yellow；
In addition to this coating has certain hydrophobic ability, can reduce the surface energy of coating, reduces influence of the liquid substance to coating,
The service life for promoting product can assign the function of coating hydrophobic oleophobic simultaneously.
