Description
Technical field
The present invention relates to macromolecular material utilisation technology and superfine function field of material technology, particularly relate to a kind of glass paint and the preparation method and application that eliminate light pollution.
Background technology
Pollute for the reflected light eliminating glass at present and there is no mature technology, glass directly covers by the general external pasting film mode that adopts.Solving light pollution problem is adopt external pasting film to be directly covered on glass to achieve the goal at present substantially, external pasting film in use, due to its easily oxidized, hardness is low, sticking power is low, not water-fastness etc. all not ideal, therefore easily exist in actual use and fade, easily scratch, easily come off, easily roll up angle, easily alice and there is the problem of seam, thus make its work-ing life short, be generally some months just to need to change, further increase the Cost Problems solving light pollution problem; Affect the overall appearance of building glass curtain wall; Affect indoor lighting.
Summary of the invention
The invention provides a kind of glass paint and the preparation method and application that eliminate light pollution, solve exist when external pasting film eliminates glass light pollution problem in prior art low, the easy scuffing of external pasting film hardness, weathering resistance is poor, water-wash resistance is poor etc. affects problem in its in work-ing life.
The present invention is realized by following technique means:
Eliminate a glass paint for light pollution, comprise:
Organosilicon ceramic resin 30%-55%;
1-8% SiO 2 powder dispersion liquid 20-60%;
Other auxiliary surpluses.
Wherein, other described auxiliarys comprise:
Flow agent 1-3%;
Solidifying agent 0.1-1%;
Mixed solvent surplus.
Wherein, the preparation method of described organosilicon ceramic resin is sol-gel method, namely gets 1mol tetraethoxy respectively, 0.5mol deionized water, 2mol dehydrated alcohol; By deionized water and dehydrated alcohol mixing and stirring, then slowly add in tetraethoxy, all add after in tetraethoxy until alcohol water mixed solution, the pH value regulating mixed system with dilute hydrochloric acid is 4-5, the reagent bottle sealing of mixing solutions will be housed and heat 1h at 45-60 degrees Celsius of lower constant temperature water baths; Solution to be mixed adds 2mol γ-methacryloxypropyl trimethoxy silane and 1.5mol isobutyl triethoxy silane wherein after being cooled to room temperature, and 30min is stirred under normal temperature (20-30 degrees Celsius), then deposit 7 days in room temperature lower seal, obtain required inorganic film-forming resin.
Wherein, described coating can be applied as the light barrier film of vehicle glass or glass of building.
A preparation method for described glass paint, adopts sol-gel method, by hydrolysis and the polycondensation film forming of alkoxide by the organosilicon ceramic resin of described weight part; Be that the SiO 2 powder of 3 μm becomes mixed solution system by the proportions of 1%-8%wt by median size; Stir 15-30min, can be disperseed and stablize good SiO 2 powder dispersion liquid, then choose each component according to above component and ratio, mixing and stir half hour more than must light pollution delustring film.
After the glass paint use of the elimination light pollution more than realized, long service life, good weatherability; Hardness is high, strong adhesion, water-fastness; Daylighting is good, can not increase interior lighting cost; The overall aesthetics of building can not be affected; Easy to operate, component ratio can be regulated according to different real case thus surface gloss needed for obtaining, reach different extinction effects.
