Abstract
The present invention is a kind of anti-fog and antifrost agent of windshield, mainly is made up of tensio-active agent, glycerine, ethanol, sprays, essence.The maximum characteristics of the present invention are that the anti-fog and antifrost timeliness is long, and stability is high, and is easy to use, in wheel house internal and external temperature difference greatly, under the relative humidity condition with higher, all can keep good antifog, antifrost effect.
Description
The present invention is a kind of chemicals that changes glass surface character, makes on glass to be difficult to form water smoke and frost.
Mist on glass, frost all are that the water in the glass surface absorbed air causes.The former is each adsorption site skewness of glass surface, and characterization of adsorption is not quite identical, thereby the water that causes adsorbing is uneven distribution and forms droplet; When the latter then showed as low temperature, water smoke dripped to congeal into ice and causes.These phenomenons appear at glass temperature usually and are lower than air themperature with glass contact, and airborne relative humidity takes place when big.This odjective cause of knot mist frosting occurs when automobile travels in the winter time just on windshield.
Present existing glass antidimmer, anti-creme, defrosting compound etc., its function all is to prevent that steam is at glass upper fogging or icing, the defrosting de-misting agent product that patent 1048052 is released is characterized in that adopting low mass molecule alcohol and magnesium chloride to reduce the freezing point of water, to reach the purpose of defrosting.If frosting on glass is thin or the defrosting compound consumption is too much, then magnesium chloride can not taken away fully by the water that frost is melted into, easily influence sight line at formation salting stain on glass: patent 1048053 then is to utilize occlusion to reduce the freezing point of water at ethylene glycol on glass and propylene glycol, but the two is more volatile, and antifrost effect is difficult to lastingly.Patent 1046548 features are to utilize the ability of silicone oil with the luminance brightness that increases glass and anti-water, mist, frost.But silicone oil is difficult for disperseing in polar solvent, even there is tensio-active agent to exist, and long also easily layering storage period.
At above-mentioned situation, make for providing that the glass transparent degree is good, antifog, the frost prevention timeliness is long, stable chemical performance and the anti-creme of vehicle glass easy to use, the spy finishes the present invention.
Feature of the present invention is:
1. adopt composite nonionogenic tenside to occupy activated adsorption point positions all on the glass surface, make and form layer of even tensio-active agent film on the glass surface, thereby airborne moisture is evenly distributed being adsorbed onto on the glass surface, do not influence the transparency of glass, reach anti-fog effect.
2. add glycerine,, reduce the freezing point of water, to reach antifrost effect with the tensio-active agent acting in conjunction that is adsorbed on the glass surface.Because the volatility of tensio-active agent, glycerine is low, the anti-fog and antifrost effect is lasting.
3. be solvent with ethanol, because ethanol is volatile, the tensio-active agent film of being convenient on glass surface forms rapidly during use.
4. add sprays so that easy to use.
5. add essence, be beneficial to the air atmosphere of regulating in the wheel house, reduce the sense of discomfort that fuel oil and its waste gas after burning produce the people.
The present invention's (percentage composition refers to volumn concentration) composed of the following components:
1. the composite mixture 1～10% of nonionogenic tenside can be fatty acid polyglycol ester, lipid acid shrink sorbitol ester ethylene oxide condensate, Fatty Alcohol(C12-C14 and C12-C18) ethylene oxide condensate, alkylphenol ethylene oxide condensate, diethanolamine of fat acyl, siliceous and fluorine-containing two kinds or three kinds of composite forming such as nonionogenic tenside.Wherein there is siliceous or fluorine-containing nonionogenic tenside to participate in that performance is good when composite.
Compound proportion: two components are mixed: 1: 0.1～10
Three components are mixed: 1: 0.1～10: 0.1～10
2. glycerine 1～10%
3. concentration is that 90～95% ethanol is as solvent 80～94%.
4. propellant 0～4%, can use propane, butane and pressurized air.
5. essence, consumption is less than 0.4%.
During use,, can reach the anti-fog and antifrost effect as long as be sprayed on this anti-fog and antifrost agent on the windshield or wipe equably on glass.
