Abstract

The antifrost liquid for glass is prepared from sodium (or potassium) stearate as surfactant, glycerine or isopropanol as antifreezer, sodium thiosulfate as antioxidant, n-butanol or n-pentanol as developer, a-pinene as organic solvent and small amount of perfume through mixing, and features simple preparing process, low cost, high antifrost effect and no toxic and corrosive pollution.

Description

Anti-frost liquor for glass

It is raw material that the present invention adopts tensio-active agent, developping agent, oxidation inhibitor and organic solvent, adds a small amount of spices and is hybridly prepared into anti-frost liquor.It is applicable to the windowpane frost prevention of public places such as Motor vehicles, school, hospital, station waiting room.The invention belongs to the technology of chemical technique aspect.

Before this, the patent application of existing CN1060670, CN1048052, relevant vehicle glass frost prevention defrosting deicings such as CN8610679, CN1076711, wherein great majority lay particular emphasis on the problem that solves the defrosting deicing aspect, the prescription complexity that has, the cost height is not easy to promote and produces.In the winter of cold, the windowpane of the ward of the Motor vehicles in travelling (especially passenger vehicle), classroom just at school, hospital and the public places such as waiting room at station, because its internal-external temperature difference is bigger, the gas that people breathe out is attached to the cold one-tenth frost of chance on glass.Frost has been blocked driver's sight line, and the Lou Quan that influences automobile travels, the enthusiasm of passenger's mood, student study; With rehabilitation of patient or the like.In view of this, purpose of the present invention aims to provide the anti-frost liquor that a kind of cost is low, easy to use, obvious results is applicable to glass (especially being suitable for the glass of Motor vehicles in travelling).

This anti-frost liquor spray is wiped on glass, and outside temperature is frost-free under 0 ℃ to-40 ℃ condition, can keep 1-15 days (more than).

The present invention utilizes the antifreeze principle that reduces freezing point after the glycerine moisture absorption, adopts tensio-active agent, developping agent and oxidation inhibitor, quickens the soap dissolving, prevents that its oxidation from solidifying, and is convenient to spray and wipes, the stability when guaranteeing that anti-frost liquor is stored.

Prescription of this anti-frost liquor and technical process are:

A. fill a prescription composition and dosage thereof:

10%-45% sodium stearate or potassium stearate (also available soap substitutes) 50-100ml; Glycerine (or Virahol) 20-50ml (deciding) according to desired freezing point height; Propyl carbinol (or Pentyl alcohol) 10-30ml (amount according to soap is decided); Sodium thiosulfate accounts for the 5-10% (also can save need not) of total amount; A-firpene 5-20% (also can save need not); Spices 0.1-0.5%.

B. preparation process is:

Get 30% soap (or soft soap) 58ml and add sodium thiosulfate 5g, add propyl carbinol (or Pentyl alcohol) 12ml, water proof heat just soap molten molten till, add a-firpene 6ml (also can save and not add), glycerol adding (or Virahol) 24ml, spices a little, filter packing.

This anti-frost liquor is compared with present like product, have that desired raw material is easy to get, blending process is simple, cost is cheap, use is easy and simple to handle, antifrost effect is remarkable, to people's safety non-toxic, to door and window non-corrosiveness, environmentally safe, be ideal anti-frost liquor for glass comparatively at present.

Claims

1. anti-frost liquor for glass is to be cooperated by tensio-active agent, frostproofer, oxidation inhibitor, developping agent, organic solvent and a small amount of spices to form.Its composition characteristic is:
