Abstract
The invention discloses environmentally-friendly deicing/anti-icing solution, which belongs to the technical field of eliminating and preventing ice covering of a transportation tool by using a physical method. The environmentally-friendly deicing/anti-icing solution comprises a freezing point depression compound, water, a surfactant and a thickening agent, wherein the freezing point depression compound is at least one of propanediol and polybasic alcohol; the surfactant is a natural surfactant; and the thickening agent is a natural product. The components of the environmentally-friendly deicing/anti-icing solution can be degraded by microbes; and the environmentally-friendly deicing/anti-icing solution generates small hazard to the environment, and is environmentally-friendly.
Description
Technical scope
The present invention relates to a kind of environment-friendly type deicing/anti-icing liquid, belong to physical method and eliminate and prevent the vehicle surface technical field of freezing.
Background technology
Under the very low situation of temperature, run into rainy, snow, during weather such as humidity is very big, transportation means, as: surface such as automobile, train, aircraft can freeze, frosting, accumulated snow.Vehicle surface is frozen, frosting, accumulated snow not only can influence sight line, and affect to running at high speed, especially aircraft, these accumulated ice, long-pending frost and accumulated snow must be removed before taking off, otherwise increase aircraft weight, influence the function and the performance of aircraft, even can cause pernicious aircraft accident.
Deicing/anti-icing liquid comprises at present: freezing point reduces compound, water, tensio-active agent, thickening material, and some other functional substance.Freezing point reduces material and is divided into inorganics and organism.What inorganics was the most frequently used is chlorine-containing compound, and it is remarkable, cheap that freezing point reduces effect, but metal is corrosive, the deicing of it goes without doing substantially transportation means and anti-icing.Organism is commonly used sodium acetate, ethylene glycol, propylene glycol etc.Wherein be usually used in the deicing of transportation means and anti-icing with ethylene glycol, propylene glycol.Tensio-active agent is mainly used in the surface tension that reduces deicing liquid, and commercially available numerous emulsifiers and combination can be used for deicing/anti-icing liquid.Thickening material is used to increase the viscosity of deicing/anti-icing liquid, keeps anti-icing performance.But there is certain hazardness in used deicing/anti-icing product to environment and human body mostly at present.
Summary of the invention
The purpose of this invention is to provide a kind of environment-friendly type deicing/anti-icing liquid, the component overwhelming majority is a natural product, and minority is the low toxicity synthetic product.
A kind of environment-friendly type deicing/anti-icing liquid of the present invention, comprise: freezing point reduces compound, water, tensio-active agent, thickening material, wherein to reduce compound be at least a in propylene glycol, the polyvalent alcohol to freezing point, weight content is 40%～95%, the freezing point of water can be reduced by 5 ℃～30 ℃, polyvalent alcohol is as glycerine, Xylitol, sorbyl alcohol, the LD50:21000～32200mg/kg of propylene glycol (rat oral); 22000mg/kg (its mouse oral), Xylitol, sorbyl alcohol can be used as food or foodstuff additive use, and human body, animal, microorganism almost are safe from harm.Tensio-active agent adopts natural surface active agent, as: sucrose ester, Yelkin TTS, lanolin, albumen etc., content 0.1%～10% can reach 30～50mN/m with the surface tension of deicing liquid/anti-freeze fluid
-1Though these natural surface active agents are harmless substantially to human body, animals and plants, microorganism not as the tensio-active agent surfactivity height of chemosynthesis.Thickening material adopts natural product, as: Mierocrystalline cellulose, starch, xanthan gum, gelatin etc., content 0.05%～5%.Thickening material is natural product, and is to can be used as food and fodder additives, harmless to people and animals and plants.
Composition of the present invention all can be degraded by microorganisms, and is less to environmental hazard, is a kind of environment-friendly type deicing/anti-icing liquid.
