Abstract
The invention relates to a preparation method of an environment-friendly organic composite salt snowmelt agent. According to the method, humic acid is compounded with sodium ions to form a humic acid associated complex, i.e. the organic composite salt snowmelt agent causing low corrosion to carbon steel and rubber is formed. The snowmelt agent has the advantages of low corrosion, low freezing point and good snow melting effect, and effectively solves the problems of salt damage to vegetation, water pollution and soil hardening. In addition, the snowmelt agent has an anti-skidding effect for the road. The selected materials for preparing the snowmelt agent are commercially available products which are low in price and easy to obtain, so that the snowmelt agent provided by the invention is suitable for industrial application.
Description
Technical field
The invention belongs to the Snow Agent studying technological domain, particularly a kind of preparation method of organic composite salt Snow Agent of environment-friendly type.
Background technology
Snow Agent is a kind of salts substances, and snow melt salt commonly used is chloride salt, such as calcium chloride, magnesium chloride and sodium-chlor etc., but use in a large number villaumite to cause certain destruction to metal, road surface and road both sides plant.
The Snow Agent preparation method that US Patent No. 6149833 provides is the mixture that forms with sodium formiate, sodium-chlor and a small amount of stopping agent, and this invention has been measured erosion rate and reached good effect.This Snow Agent can be made into the nanoscale solids particle or is made into a certain proportion of solution and uses.But because the adding of stopping agent has increased the difficulty of Road maintenance greatly, suppressed the road growth of vegetation on both sides of the road.
The Snow Agent preparation method that Chinese patent CN1242016C provides has added the rust-preventive agent Starso in the inorganic salts Snow Agent.This material easily forms gel in solution, solvability is bad, and in actual use, the grain diameter of Starso is less, is incorporated into layering easily occurs in the oarse-grained inorganic salt, has reduced the snow melt effect of Snow Agent.
The preparation of Chinese patent CN 1657586A success environment-friendly snowmelt agent, the waste liquid that the raw material that uses is made charcoal and produced in the gas-making process as waste wood, contain a large amount of acid groups in the waste liquid, make lower carboxylic acid calcium magnesium salts Snow Agent with this waste liquid and calcium and magnesium oxides or carbonate reaction.This Snow Agent has overcome the corrodibility of chloride salt Snow Agent, has played the effect of environmental protection.But this type of Snow Agent also can only be used for airfield runway because cost is higher in developed country, and highway and town road seldom use this type of Snow Agent.
In sum, the domestic and international market Snow Agent has following FAQs at present:
(1) traditional chloride salt Snow Agent freezing point is low, and corrodibility is strong, and sodium ion and chlorion are violent to the vegetation salt damage of road both sides, polluted-water, make soil compaction, cause salting of soil.
(2) although the non-villaumite Snow Agent relative environmental protection take calcium magnesium acetate as representative, but this Snow Agent freezing point is high, the snow melt effect is relatively poor, easily freeze again after the snow melt, and non-villaumite Snow Agent is expensive, even at western developed country, also just in zone uses higher to environmental requirement such as airfield runways, highway and town road seldom use the Snow Agent of non-chloride salt.
(3) some compound snow-melting agent have added the additives such as coal ash, road is produced to some extent destroy, and have increased the cleaning difficulty of road behind the snow.
Summary of the invention
The existing price of Snow Agent of the prior art is high in order to solve, sodium ion and chlorion be to vegetation salt damage, the polluted-water of road both sides, make the problems such as soil compaction, the invention provides a kind of low freezing point, high ice-melt speed, low burn into cost low, can the anti-salt damage energy for growth of Effective Raise farm crop and play the preparation method of the environment-friendly type organic composite salt Snow Agent that promotes growth.
It is that the preparation method of this environment-friendly type organic composite salt Snow Agent is comprised of following steps that the present invention solves the problems of the technologies described above the technical scheme that adopts:
(1) at room temperature, take by weighing sodium-chlor and be configured to saturated solution, add humic acids, the mass ratio of humic acids and sodium-chlor is 1:0.4～1, and preferred 1:0.6～0.8 stirs, 60～80 ℃ of 1～3h that reflux, preferred 2h makes the Associated Solutions of humic acids and sodium-chlor;
(2) get the Associated Solutions of step (1), add pH adjusting agent regulator solution pH and reach 6.5～7, place 80～110 ℃ of heat dryings of baking oven, make organic composite salt Snow Agent;
Above-mentioned pH adjusting agent is acetate or soluble carbonate salt or supercarbonate.
Acetate in the above-mentioned steps (2) is any one in lime acetate, magnesium acetate, sodium acetate, the potassium acetate.
Soluble carbonate salt in the above-mentioned steps (2) is yellow soda ash or salt of wormwood.
Supercarbonate in the above-mentioned steps (2) is sodium bicarbonate or saleratus.
The preparation method of environment-friendly type organic composite salt Snow Agent of the present invention utilizes the complexing humic acid sodium ion, form the organic composite salt Snow Agent of humic acids associated complex, little to carbon steel, rubber corrosiveness, have low burn into freezing point low, the advantage that snow melt is effective, and effectively reduce the problem of vegetation salt damage, polluted-water, soil compaction, can play the anti-skidding effect of road, selected material is the commercially available prod, and is cheap and easy to get, is suitable for industrial applications.
