Abstract
The invention discloses a rapid deicing agent which comprises the following components in percentages by weight: 65-85 percent of denatured protein, 5-18 percent of pour point depressant, 1-15 percent of corrosion inhibitor and 0.5-5 percent of isothiazolinone. The denatured protein has the characteristics of loose molecular structure, capability of preventing freezing and easiness in hydrolyzing, so that the rapid deicing agent has a freezing point being lower than 50 DEG C below zero, long ageing and better deicing and anti-freezing effects compared with other snow melting deicing agents. The deicing agent is environmentally-friendly to vegetation, water quality and the air, has indexes up to the farm irrigation water quality standard and the national atmospheric air quality standard, is decomposed into water and carbon dioxide in soil, does not erode soil, is harmless to human skin and animals, and is up to the airport snow melting and deicing AMS (Aerospace Material Specification) 1435 standard. The deicing agent has the advantages of low viscosity, low freezing point, low using cost equivalent to one third of the using cost of an imported snow melting deicing agent, contribution to deicing in severe environments, nontoxicity, high biodegradability, corrosion resistance and environmental friendliness, is a colorless transparency liquid, and is particularly suitable for winter deicing operation in airports.
Description
Technical field
The present invention relates to a kind of deicing agent, particularly a kind of nontoxic, without the free of contamination rapid deicing agent of burn into.
Background technology
Along with warming of global climate, exceedingly odious weather is more and more, particularly the extreme weathers such as severe snow is freezing often occur in winter, is easy on the road surface or other objects form and freeze.In order to prevent that the road from sliding or other objects are damaged by frost; often need to spread deicing agent and carry out deicing; present deicing agent is mostly with certain toxicity; with water dissolution by often can shining into erosion, pollute soil, road surface or various body surface, even might human or animal's health be damaged.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provide a kind of nontoxic, without the free of contamination rapid deicing agent of burn into.
Be for solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of rapid deicing agent, it comprises following component by weight percentage: denatured protein 65-85%, pour point depressant 5-18%,, inhibiter 1-15%,, isothiazolinone 0.5-5%.
Preferably, it comprises following component by weight percentage: denatured protein 70-80%, and pour point depressant 10-15%,, inhibiter 5-10%,, isothiazolinone 1-3%.
Preferably, it comprises following component by weight percentage: denatured protein 77%, and pour point depressant 13%,, inhibiter 8%,, isothiazolinone 2%.
Technique scheme has following beneficial effect: the denatured protein molecular structure is loose in the present invention, can not form icing, facile hydrolysis, the denatured protein molecular structure can destroy the molecular structure of ice sheet inside, make in order imporosity become the stretch-like structure of the unordered loose expansion of volume as the ice-creams, make the ice molecular radical that originally is in the inside that freezes be exposed in a large number molecular surface, thereby the ice group then reduces relatively in the distribution on surface, to the ice molecular structure can not being mixed with the ice molecular structure and losing ice molecular structure film, be easy to cause and mutually stretch collision between the ice molecular structure, can see obviously and melt fast to ice structure; Change the zero pour of melting liquid by pour point depressant after melting, thereby run off fast and make ice structure melt fast hydrolysis, effect thawing water by pour point depressant can keep no longer icing from multiple junction in a very long time, inhibiter and isothiazolinone can keep various nonferrous materialss are comprised the corrodibility that do not have of soft steel, carbon steel and aluminium alloy, and corrodibility is lower than tap water.The present invention utilizes the denatured protein molecular structure loose, can not form icing, the facile hydrolysis characteristics, so freezing point is low, timeliness is long, freezing point is lower than-50 ℃, than other snow melt deicing agent better deicing antifreezing effect is arranged.Pollution-free to vegetation, water quality and air, indices meets agricultural irrigation water quality standard and air quality national standard, is decomposed into water and carbonic acid gas in soil, and is without infringement, harmless to human body skin and animal to soil.Meet airport snow melt deicing AMS 1435 standards.Have viscosity low, freezing point is low, and low quite external snow melt deicing agent 1/3rd costs of use cost help the deicing under the severe environment.It has nontoxicity and good biodegradability, is colourless transparent liquid, nontoxic, pollution-free without burn into, is particularly suitable for airport deicing in winter operation.
