Abstract
The invention relates to the field of glass antifogging agents, in particular to an automotive glass antifogging agent and a preparation method thereof. The automotive glass antifogging agent consists of the following raw materials in percentage by weight: 2 to 5 percent of methyl trifluoropropyl silicon oil, 2 to 5 percent of volatile perfluoro-oil, 2 to 5 percent of oleic acid, 2 to 5 percent of 1,5-pentanediol, 2 to 5 percent of tween-80, and the balance of water. The automotive glass antifogging agent is prepared by the following steps of: (1) dissolving the tween-80 in the water, and stirring the mixture; (2) mixing the volatile perfluoro-oil, the oleic acid and the methyl trifluoropropyl silicon oil together, and uniformly stirring the mixture; (3) pouring the liquid of the step (2) into the liquid of the step (1), and uniformly stirring the mixture; (4) pouring the 1,5-pentanediol into the liquid of the step (3), and uniformly stirring the mixture. The introduction of fluorine ensures that the antifogging agent has excellent hydrophobicity and an antifogging function, the antifogging time is prolonged, and the antifogging effect is improved; furthermore, the automotive glass antifogging agent has no side effect on human bodies, and has the functions of preventing rain, cleaning glass and protecting a wiper after the automotive glass antifogging agent is coated on external glass and a back view mirror of an automobile.
Description
Technical field
The present invention relates to the glass antidimmer field, particularly a kind of anti-fog agent for wind-screen of automobile also relates to the preparation method of this antifogging agent.
Background technology
Something that have a headache winter concerning automobile family is that glass is usually covered by fog in the car very much, seriously hinders traffic safety.The glass antidimmer that uses generally is made up of tensio-active agent, alcoholic solvent or ether solvent etc. at present, and its antifog time is generally at 1-2 days, the antifog time is short, and in addition, anti-fog effect neither be fine, when running into dense fog or severe cold weather, anti-fog effect can be very poor.
Summary of the invention
The present invention provides a kind of good antifogging effect in order to overcome the deficiency in the above technology, the anti-fog agent for wind-screen of automobile that the antifog time is long.
The present invention also provides a kind of preparation method of described antifogging agent.
The present invention realizes in the following manner.
A kind of anti-fog agent for wind-screen of automobile is characterized in that being made up of following raw materials by weight percent:
Methyl trifluoro propyl silicone oil 2-5%,
Volatility perfluor oil 2-5%,
Oleic acid 2-5%,
1,5 pentanediol 2-5%,
Tween-80 2-5%,
Surplus is a water.
Described antifogging agent is characterized in that: methyl trifluoro propyl silicone oil contains 50% trifluoro propyl substituting group, and relative molecular mass is 190000-210000.
The preparation method of described antifogging agent is characterized in that adopting successively following steps:
(1) tween-80 is dissolved in the water, is stirred to and is uniform liquid;
(2) volatility perfluor oil, oleic acid and methyl trifluoro propyl silicone oil are mixed, be stirred to and be uniform liquid;
(3) liquid of step (2) is slowly poured in the liquid of step (1), the limit bevelling is stirred to and is uniform liquid;
(4) 1,5 pentanediol is poured in the liquid of step (3), stirred.
Methyl trifluoro propyl silicone oil and volatility perfluor oil are owing to introduced fluorine atom, surface energy descends, hydrophobicity increases, water contact angle increases, have good hydrophobicity performance, under the effect of gravity, fog can tumble along glass surface than being easier to condense into the globule, therefore, has good anti-fog effect.
The methyl trifluoro propyl SILOXANE MOLECULAR WEIGHT is 190000-210000, is called trifluoro propyl methyl-silicone oil (50% trifluoro propyl) again; The trifluoro propyl methyl polysiloxane; Fluoroalkylsiloxane polymer; Methyl-silicone oil (50% trifluoro propyl substituting group).
Volatility perfluor oil dilutes the mixture that forms for being base oil with the fluorinated oil with the volatility perfluoro solvent.
Oleic acid is 18 carbon-suitable-9-olefin(e) acid, is a kind of important component that constitutes the animal and plant grease.
Tween-80 is being commonly called as of tensio-active agent Tween-80.Molecular formula: C
64H
124O
26, yellowish to orange-yellow thick liquid.
Beneficial effect of the present invention: the introducing of fluorine makes antifogging agent of the present invention have good hydrophobic nature and anti-fog function, anti-high temperature, and contamination resistance strengthens, and can prolong the antifog time, improves anti-fog effect; Use range is wide, cost is low, human body is had no side effect; That antifogging agent of the present invention is wiped is rainproof in addition on the glass and rear vision mirror outside automobile, the effect of cleaning glass, protection wiper; Make water as solvent, do not have danger inflammable and blast, be easy to carry.
