Abstract
Steam and fog clear of the present invention is a kind of decontamination, antifogging agent that is applicable to glass or surface of plastic products.It is formulated by 2-4 part (weight, as follows) sodium lauryl sulphate, 3-6 part polyoxyethylene polyoxypropylene monobutyl ether and 90-95 part water, and it is cheap and easy to get to have a raw material, safety non-toxic, antifog characteristics such as respond well.
Description
Steam and fog clear of the present invention is a kind of decontamination, antifogging agent that is applicable to glass or surface of plastic products.
Antifogging agent is at home and abroad studied widely and is used.Japanese Patent (JP87,184,086) provides a kind of antifogging agent, and anti-preferably fog effect is arranged.But this antifogging agent is a raw material with anion surfactants such as fluorine system or sulfosuccinate dialkyls, and this type of cloudy class sub-surface promoting agent is buied in China at present domestic still being difficult for, and price is higher.
The object of the present invention is to provide a kind of good antifogging effect, raw material is inexpensive, be easy to get the antifogging agent of safety non-toxic.
It is raw material that the present invention adopts sodium lauryl sulphate and polyoxyethylene polyoxypropylene monobutyl ether, with they water-soluble steam and fog clears that is mixed with.Concrete prescription is: sodium lauryl sulphate 2-4 part (weight, as follows), polyoxyethylene polyoxypropylene monobutyl ether 3-6 part, water 90-95 part.
Sodium lauryl sulphate be a kind of colourless, do not have smell, the anion surfactant of toxicological harmless, domestic mass production, cheap.Polyoxyethylene polyoxypropylene monobutyl ether is a kind of glass scavenger specially, and it has characteristics such as colourless, nontoxic, flash-point height, selects for use the polyoxyethylene polyoxypropylene monobutyl ether of molecular-weight average about 4000 can satisfy the requirement of preparation steam and fog clear well.
Steam and fog clear of the present invention is sprayed on glass or surface of plastic products, can form effective anti-fog thin film, has good anti-fog effect, and with low cost, safety non-toxic.Steam and fog clear of the present invention is to the harmless effect of materials such as glass, plastics, often uses this steam and fog clear can make glass or surface of plastic products brighter and cleaner, bright and clean, and glass, plastics become more transparent.Problems such as the present invention adopts water as solvent, does not therefore have organic solvent such as alcohol and causes atmospheric pollution, and is inflammable, explosive, and cost is cheaper.
Below be specific embodiment:
1,2 parts of (weight, as follows) sodium lauryl sulphate and 3 parts of polyoxyethylene polyoxypropylene monobutyl ethers are dissolved in 95 parts of water, add the steam and fog clear that an amount of food flavour promptly makes good anti-fog effect.
2,4 parts of (weight, as follows) sodium lauryl sulphate and 6 parts of polyoxyethylene polyoxypropylene monobutyl ethers are dissolved in 90 parts of water, add an amount of food flavour, promptly make the steam and fog clear of good anti-fog effect.
Claims (3)
1, a kind of antifogging agent that is used for glass or frosting is characterized in that by sodium lauryl sulphate, polyoxyethylene polyoxypropylene monobutyl ether and water formulated.
2, antifogging agent according to claim 1 is characterized in that the weight percent of each component is as follows: sodium lauryl sulphate 2-4; Polyoxyethylene polypropylene single-butyl ether 3-6; Water 90-95.
3, according to claim 1 and 2 described antifogging agents, the molecular-weight average that it is characterized in that polyoxyethylene polyoxypropylene monobutyl ether is about 4000.
