Abstract
The invention provides a kind of antifogging and antifrosting agent that is used on the automobile wind shield glass, mix by ethylene glycol, propylene glycol, water and butane.The proportioning of temperature ethylene glycol and propylene glycol in the time of-10 to-45 ℃, from 10: 1 to 3.44: 1 scope, select, and the proportioning range of choice of total alcohol amount and water is 5: 4 to 8: 1, at this moment, under various different temperature conditions, all can obtain the composition that the antifrost antifogging effect is best, cost is minimum.
Description
The present invention relates to a kind of composition that is used for having on the automobile wind shield glass frosting resistance knot mist character.More particularly, this composition involved in the present invention can be coated onto on the automobile wind shield glass, so that remove frost mist from the surface, and stays the continuation generation that can prevent frost, mist on the surface.
At the arctic weather in winter, automobile outdoor park or driving process in since in the wheel house with the extraneous temperature difference, be easy on the windshield generate one deck frost mist, and block driver's sight line, bring serious threat for the safe driving of automobile.
Chinese patent CN86106796A has disclosed a kind of antifogging and antifrosting agent for glass, has solved an above difficult problem preferably.As a kind of antifogging and antifrosting agent, must satisfy many technological standard requirements, and one of most important technological standard be exactly automobile in the process of moving, composition should be able to be trapped in the windshield surface long period, keep antifrost effect within a certain period of time, coat after this composition, it is Clear ﹠ Transparent that windshield should keep, unaffected to driver's sight line.Another problem that will consider of the antifogging and antifrosting agent that provides is that antifogging agent should be able to use conventional spraying plant coating.This in addition liquid should have package stability preferably.
Except above-mentioned requirements, a kind of good antifogging and antifrosting agent also should allow it not have obvious corrosion, should the toxicity minimum to the people, do not have flammable danger, and the cost of product is low as far as possible.
Antifrost antifogging composition of the present invention comprises following composition:
A) contain 40-80%(weight) alcohol mixture, said alcohol mixture is the mixture of ethylene glycol and propylene glycol;
B) contain 10-50%(weight) water;
C) contain 10%(weight) polyoxyethylene alkyl phenyl ether.Said polyoxyethylene alkyl phenyl ether is a kind of adhesive agent, have adhere to, wetting action, can make composition longtime drying of the present invention, it can get rid of the frosting material, makes the easier film forming of ethylene glycol and propylene glycol.
D) contain the butane of 0-3%, butane mainly is as sprays, makes the composition can be with conventional spraying plant coating.Can certainly use other sprayss,, and be coated with general smearing method perhaps without sprays.
Though ethylene glycol has the antifreeze effect of good frost prevention, persistence is not good enough, and the present invention has added the mixture that propylene glycol is formed, and has improved the frost protection effect of composition, has strengthened the frost prevention enduring quality.The advantage of the present composition is just to provide best proportioning according to ambient air temperature, makes composition under different temperature conditions, and good frosting resistance, antifog character are arranged, and this moment product cost minimum.The present invention is by under varying environment temperature, selects the ratio of mixture of ethylene glycol and propylene glycol, and total pure weight with the ratio of water consumption reaches above purpose.When temperature during at-10 ℃ to-45 ℃, the proportioning of ethylene glycol and propylene glycol is selected from 10: 1 to 3.44: 1 scope, and total alcohol amount is then selected from 5: 4 to 8: 1 proportional range with the proportioning of water.When temperature is-10 to-25 ℃, the preferred proportion of ethylene glycol and propylene glycol proportioning is 10: 1 to 5.19: 1, total alcohol amount is 5: 4 to 2: 1 with the proportion optimization ratio of water, when temperature is-25 ℃ to-35 ℃, the preferred proportion of ethylene glycol and propylene glycol proportioning is 5.19: 1 to 3.96: 1, and always pure heavy and proportion optimization ratio water is 2: 1 to 7: 2; When temperature was-35 to-45 ℃, the preferred proportion of ethylene glycol and propylene glycol proportioning was 3.96: 1 to 3.44: 1, and total alcohol amount is 7: 2 to 8: 1 with the proportion optimization ratio of water.Low temperature condition proportioning value composition down is used for than high temperature condition defrosting down, and the composite formula as-45 ℃ the time is used for that defrosting is fine certainly under-10 ℃ to-35 ℃ temperature conditions, is that at this moment product cost is higher.But conform with than the composition proportioning under the high temperature condition, be used for the defrosting down of low temperature condition, the composition proportioning as-10 ℃ the time defrosts when being used for-20 ℃ to-45 ℃, then can not reach the defrosting effect when resembling-10 ℃.Provided by the invention to select the different compositions proportioning according to ambient air temperature be preferred, economic method so resemble.
Composition of the present invention does not have corrodibility, and is nontoxic to human body, do not have flammable danger yet.Enumerate several examples of the present invention that under the varying environment temperature condition, use below.As an illustration, but anything but in order to limit the scope of the invention, each composition has good antifrost antifogging effect under corresponding temperature condition, spray on the automobile wind shield glass, frosting all do not occur through 24 hours, and glass surface is the transparent and uniform liquid film.
