Technical field
The invention relates to a kind of composition of tool ultraviolet absorption ability.The present composition can be prepared into coating, is coated on the base material, so that reach anti-UV effect through the base material that applies, and have good weathering resistance.
Background technology
Generally speaking, ultraviolet ray general reference wavelength is between the hertzian wave of 100nm to 400nm.No matter ultraviolet ray is that people, environment or material are all had many adverse influences, if for example human body tans by the sun too much ultraviolet ray, is easy to generate cataract, skin carcinoma, burns and symptom such as thickization of skin; Yellow and embrittlement situation if then take place through the long-time irradiation of ultraviolet ray in material easily.Therefore people constantly seek strong and effective ultraviolet absorption material for many years, as UV light absorber, but UV light absorber is an organic substance, has short, shortcoming such as toxicity is big of life-span, for improving above-mentioned shortcoming, progressively development uses the nano grade inorganic particulate to replace UV light absorber recently.
Though inorganic particles can overcome the shortcoming of UV light absorber, stronger than UV light absorber again to ultraviolet receptivity, but inorganic particles mostly is powder or sol-gel (sol-gel), be difficult for coating on the base material, thus need to add joint compound (binder), but general joint compound, its weathering resistance is not good, therefore the coating that uses inorganic particles to make, after oxidation, degraded, phenomenon such as cause film aging, efflorescence easily, split even come off.
This case the contriver find through broad research, inorganic particles is added fluoroplast, neither change the ultraviolet characteristic of the high absorption of inorganic particles, can utilize the high bond energy of C-F key in the fluoroplast again, improve weathering resistance, and fluoroplast has pollution resistance, can produce self-cleaning effect, so can effectively solve its shortcoming.
