The preparation method of glass hydrophobic film coating liuqid is among each embodiment:
Chain alkyl siloxanes and an amount of alcohol mixed and stir obtain solution I, water, hydrochloric acid, an amount of alcohol are mixed and stir and obtains solution II, II is dropwise splashed among the I, vigorous stirring finally obtains solution III simultaneously; Alkyl silicate and an amount of alcohol mixed and stir obtain solution IV, water, hydrochloric acid, an amount of alcohol are mixed and stir and obtains solution V, V is dropwise splashed among the IV, vigorous stirring finally obtains solution VI simultaneously; The PH that regulates III and VI with hydrochloric acid mixes III and VI then to close, and vigorous stirring makes it evenly obtain solution VII simultaneously, is the described hydrophobic liquid of these claims.
Long chain alkyl silane coupling agent molecule structural formula is R1-Si-(OR2) in the present embodiment
(3-x)-(CH3)
xWherein, alkyl R1 contains 7～18 carbon atoms; R2 be methoxyl group, oxyethyl group or propoxy-wherein any one; 1～3 hydrolyzable alkoxyl group is promptly contained in x=0～2 in the molecule, for example octyl group Trimethoxy silane, iso-octyl triethoxyl silane, dodecyl methyl siloxanes, octadecyl dimethyl siloxane etc.
Through verification experimental verification, water droplet is on the glass surface of unprocessed, common hydrophobic treatment, this patent hydrophobic treatment the time, and the contact angle of water droplet is respectively 15 °～30 °, 60 °～80 ° and 100 °～115 °.
Product of the present invention adopts nanotechnology production, form polymer layer after can filling up the micropore of body surfaces such as glass, plastics rapidly, form the smooth transparent film of one deck, the surface is no longer got wet, raindrop are difficult to adhere to, thereby sleet is tumbled fully on windshield glass, vehicle window or helmet eye-protection glasses, and can increase substantially transparency, for the officer obtains the visual field clearly, improve the security of rainy day driving, when running at high speed, the big more effect that rains more obviously.And this product has superpower self-cleaning function, effect such as waterproof, dustproof, antiscale, and can reduce using and wearing and tearing of rain brush.This hydrophobic film coating liuqid is equally applicable to mirror, glass table, glass shower dividing plate and screen etc., is a kind of multi-functional antirain agent.Product safety is nontoxic, can not work the mischief to human body and environment.
During the plated film construction, earlier glass surface is thoroughly removed no greasy dirt, dust (surface is cleaning more, and effect is good more), made its surface drying, with draw a circle form be evenly coated in surface after dropping on the dried cloth again to hydrophobic film coating liuqid, after the surface forms film, be coated with again once, in several seconds such as summary, use clean soft cloth from top to down then instead and wipe unnecessary hydrophobic film coating liuqid, treat the hydrophobic film drying, can show hydrophobic effect, about 30 minutes, decide with envrionment temperature.Hydrophobic film coating liuqid is not suitable for smearing with sponge kind, and please don't contact wetting and washing composition before dry.
By the hydrophobic film that above-mentioned construction produces, hydrophobic effect is strong, and waterproof is superior, water droplet with processed after surface when contacting, contact angle value height, suitable inclination can tumble automatically and leave no trace; Hydrophobic protective layer is 3-D solid structure, and coating can not come off, non-scale, and abrasion resistance is strong; And acid and alkali-resistance, anti-high and low-temp, environmental compatibility is strong, no matter four corners of the world side, in season spring, summer, autumn and winter, the high temperature severe cold all is suitable for, but coating heatproof-70 is ℃ to 150 ℃; After using the present invention's product, can prolong auto parts machinery work-ing life, make dust, the grains of sand, the easier removing of acid-base material, thereby reduce the rain brush access times, friction reduces, and prolonged work-ing life; Can reduce labor intensity effectively and the expense of cleaning supplies, reduce the carwash number of times, shorten car-cleaning time; Another characteristics of product of the present invention are safety and environmental protections in addition, generally get final product with clear water during scouring, do not need any sanitising agent, reduce secondary pollution, and are time saving and energy saving, easy to use, need not the professional, service free and maintenance.
Product application of the present invention has all obtained extraordinary effect on cowl, window-glass and glasses.
At last, it is also to be noted that what more than enumerate only is specific embodiments of the invention.Obviously, the invention is not restricted to above examples of implementation, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
