Description
Technical field
The present invention relates to a kind of Snow Agent, be specifically related to a kind of environment-friendly snowmelt agent and preparation method thereof.
Background technology
Tradition Snow Agent is villaumite type Snow Agent, and its composition is or containing inorganic villaumites such as sodium-chlor, magnesium chloride, calcium chloride, is wherein Main Function composition with calcium chloride.Due to Cl-corrodibility, often with the addition of rust inhibitor (resist), although relax to some extent metal and pavement construction material corrodibility, corrodibility is still very outstanding, and Cl-have an impact to soil, vegetation, harm plant-growth.Given this, afterwards villaumite type Snow Agent was improved, if number of patent application is 201410512480.X, patent name is: efficient villaumite Snow Agent of a kind of low corrosion and preparation method thereof, disclose the efficient villaumite Snow Agent of a kind of low corrosion, it is by sodium-chlor 85-98%, inhibiter 1-10%, auxiliary agent 1-5% is prepared from by weight, although solve etching problem to a certain extent, but still it is low to there is Snow-melting speed, to the problem such as metal protection is serious, after ice dissolution, road surface slippery situation, and the environment-friendly snowmelt agent of really.
Garlic (Garlic) cries again the head of garlic, Bulbus Allii head, giant garlic, calabash, solely garlic, single clove garlic, is the general designation of garlic class plant, and garlic is " borough chief's microbiotic out ", has natural broad-spectrum antimicrobial characteristic.At present, a lot of at the research report in antibacterial to garlic both at home and abroad, it all has suppression and killing action to various bacteria, fungi and protozoon, is proved to be a kind of green natural biological preservative, has the special performances such as safe, efficient, natural.Garlic can suppress the growth of spoilage organism in most of food and pathogenic bacterium, and in order to be applied to, food antiseptic is fresh-keeping has established theoretical basis to these characteristics.But the domestic and international report of the research for Antibacterial Action of Garlic but more concentrates on the extract of garlic at present: Oleum Bulbus Allii, garlicin etc. are to the suppression aspect of microorganism, and it is little to obtain the research of juice in ice melting agent with whole crushing garlic, do not find there is similar relevant report both at home and abroad.
Summary of the invention
The object of the invention is to, for above-mentioned the deficiencies in the prior art, provide a kind of environment-friendly snowmelt agent, snow melt efficiency is high, convenient transportation, uses storage safe; Be convenient to spray, use labour intensity low, artificial input is little; Snow-melting speed is fast, noresidue, not polluted source; The present invention also provides its preparation method, and technique is simple, is easy to suitability for industrialized production.。
Technical scheme of the present invention is achieved in that
A kind of environment-friendly snowmelt agent, the raw material primarily of following parts by weight forms: garlic juice 2-14 part, sodium-chlor 1-5 part, calcium chloride 8-32 part, plant ash 1-14 part, SODIUMNITRATE 1-10 part, silicate 1-5 part, borax 1-3 part, poly carboxylic acid 0.05-1.8 part, thionamic acid 0.08-1.5 part;
The polymerization degree n of described poly carboxylic acid is arbitrary value in 2-6.
Preferential, described environment-friendly snowmelt agent, the raw material primarily of following parts by weight forms:
Garlic juice 5-12 part, sodium-chlor 2-8 part, calcium chloride 10-26 part, plant ash 3-9 part, SODIUMNITRATE 2-8 part, silicate 1.5-4.5 part, borax 1.2-2.6 part, poly carboxylic acid 0.08-1.2 part, thionamic acid 0.1-1.2 part;
The polymerization degree n of described poly carboxylic acid is arbitrary value in 3-5.
A preparation method for environment-friendly snowmelt agent, comprises the following steps:
(1) described sodium-chlor, calcium chloride, plant ash, SODIUMNITRATE, silicate, borax, poly carboxylic acid, thionamic acid are pulverized, mix, stirred;
(2) by described garlic squeezing gained the garlic juice evenly vaporific mixture be sprayed on described in step (1);
(3) be squeezed into the particle of 0.2-1.9mm, obtain environment-friendly type environment-friendly snowmelt agent.
the mechanism of action:snow Agent with liquid or solid-state sow after, form dilute solution with ice and snow on road surfaces.The character of dilute solution meets Raoult's law, from Raoult's law: the existence of solute can reduce the vapour pressure of solvent, when being dissolved with a small amount of solute B in solvent orange 2 A and forming dilute solution, then the temperature (zero pour of ie in solution) separating out solid pure solvent orange 2 A from solution will lower than the zero pour of neat solvent in same outer pressure.This is depression of the freezing point phenomenon, and namely freezing point reduces theoretical.Snow Agent of the present invention is the mixture of numerous pharmaceutical chemicals, and its each component reduces the excellent amount of synergy of freezing point.
Water freezes at 0 DEG C, and the aqueous solution of water-soluble chemical substance can reduce the vapour pressure of water, thus reduce the freezing point of the aqueous solution, the concentration of salts solution is higher, and the freezing point of solution is lower, therefore the solution of Snow Agent is at low temperatures still for liquid and do not freeze.Winter uses Snow Agent when subzero temperature snowfall, and when the freezing point of the solution that Snow Agent and snow-broth are formed is lower than temperature, snow just flows away with the form of salts solution, thus reaches the object of road surface snow removing.
compared with prior art, Advantageous Effects of the present invention is as follows:
1. different from other Snow Agent, although Snow Agent prepared by the present invention is containing inorganic villaumite, but it is minimum to metallic corrosion, garlic raw material used is foodstuff additive, also can not damage human body even if other materials are edible, environmental protection, extremely low to environmental hazard, Snow Agent of the present invention water suction, anti-skidding.
2. the Snow Agent snow melt efficiency that obtains of the present invention is high, convenient transportation, uses storage safe; Be convenient to spray, labour intensity is low, and artificial input is little; Consumption is few, and Snow-melting speed is fast, noresidue, does not corrode building and road surface, does not injure plant and hydrocoles, not spoiled soil pH, can not cause salting of soil.
3. the invention solves traditional snow melt product to the etching problem of road and bridge reinforcing bar, reduce Snow Agent to greatest extent to the impact of road and environment and destruction, and this product is applicable to the low temperature environment of-50 DEG C, suitable environment is more extensive.
4. main raw material of the present invention is natural phant and is extensively easy to get, and is conducive to environment protection, and cost is low, and preparation technology is simple, is easy to suitability for industrialized production.
