Description
Technical field
The present invention relates to a kind of deicing salts.Specifically, the present invention relates to one kind using organic salt as main component, is free of chlorine
The environment-friendly snowmelt agent of element.
Background technique
Deicing salt includes two kinds of villaumite type and non-villaumite type.
Villaumite type deicing salt is from a wealth of sources, cheap, is most common deicing salt.But chloride ion radius is small, penetrates
Power is strong, can destroy metal surface protection layer, so that metal is generated pitting and stress-corrosion cracking, to infrastructure and driving vehicle
With very big harmfulness.A large amount of chloride ions contained by villaumite type deicing salt, the infiltration of water can be blocked by penetrating into soil, and one
Denier vegetation root chlorinity is excessively high, branches and leaves will withered death, destroy the green vegetation on road periphery, cause serious danger
Evil.In addition, be discharged into both sides of highway and surrounding farmland after villaumite type deicing salt is dissolved in ice and snow, make earth's surface salination, it can also be impurely
Table water and underground water, influence the ecological balance.
Currently, non-villaumite type deicing salt mainly has the organic salts such as potassium acetate, calcium acetate magnesium salt, no image of Buddha villaumite type melts
Agent is the same is used on a large scale for snow, mainly has the following aspects: first is that acetate is at high price, second is that can release after sowing
The tart flavour of stimulation, third is that the appearance of the city can be influenced in ground residual salt marsh after acetate is dry, fourth is that calcium acetate magnesium salt can cause water source
Pollution.Therefore, non-villaumite type deicing salt can be only applied to the snow removing on airport etc. at present, can't large area use.
In recent years the environment-friendly snowmelt agent occurred, although no longer using sodium chloride as main component, and use calcium chloride or chlorination
Magnesium etc. is re-introduced into corrosion inhibiter etc., but chemically angle says that chlorine element still exists, and does not improve its harm to environment thoroughly.
Therefore, it is necessary to propose novel chlorine-free type deicing salt, harm of the chlorine element to environment is thoroughly avoided, and change with vinegar
The problems such as sour potassium, calcium acetate magnesium salt are uneconomical main component bring, penetrating odor, salt marsh, water pollution.
Summary of the invention
The purpose of the present invention is be directed to existing domestic market product deficiency, provide one kind using organic salt as main component,
Snow melt effect is good, and Snow-melting speed is fast, and snow melt timeliness is long, and ratio of briquetting is high, chlorine is free of, to facility, vehicle, plant, water body etc. without danger
Evil, sows rear odorlessness, without salt marsh, the higher deicing salt of non-slip and cost performance and preparation method thereof.
The purpose of the present invention is achieved by following technical proposals: non-chlorine environmental-protecting type deicing salt of the invention, mainly by
Following material composition (by weight percentage): sodium formate 30~40%；Urea 30~40%；Potassium acetate 15~25%；Sodium carbonate 3
~5%；Montmorillonite 3~5%；Sodium tetraborate 2~3%；Alkyl phenol polyoxyethylene ether 1~2%；Its total weight is 100%.By object
Material is weighed, is crushed, and is lower than 5 minutes through mixing in batch mixer, mixed material is sent into pelletizer by belt conveyor, sternly
Lattice control the temperature inside grain-making machine at 80~90 DEG C, extrude the material into spherical shape, screen, sealed package.
Non- chlorine environmental-protecting type deicing salt is novel green, environmental friendly product, can be by the Free water of earth's surface, absorption water, wet
Water becomes granular and is absorbed from membranaceous, and liquid phase is made to be in not icing condition, can be with the supercooled state of systems stabilisation, to greatest extent
Freeze-off time is postponed, and ice cube is made to freeze hardness reduction, is easily handled.Product can increase the fertility of soil, realize that " snow melt is applied
Fertilizer " promotes plant growth, beautifies the environment.
It is free of chlorine element, can overcome chlorine type deicing salt used at present corrosion it is strong, not environmentally the deficiencies of, and can be with
Improve at present with potassium acetate, calcium acetate magnesium salt non-the uneconomical of chlorine type deicing salt as main component, penetrating odor, salt marsh, water
The problems such as pollution, sows rear odorlessness, without salt marsh, non-slip, and sexual valence is relatively high.Snow melt effect is good, and Snow-melting speed is fast, snow melt
Timeliness is long, and ratio of briquetting is high.
Specific embodiment
The present invention is further illustrated below with reference to being embodiment, but the present invention is not limited to following embodiments.
Embodiment 1
According to usage ratio (mass percent) by sodium formate 40%, urea 30%, potassium acetate 15%, sodium carbonate 5%, cover
De- soil 5%, sodium tetraborate 3%, alkyl phenol polyoxyethylene ether 2% are weighed, are crushed, will after being uniformly mixed 3 minutes in agitated machine
Mixed material is sent into pelletizer by belt conveyor, and the temperature inside strict control grain-making machine is at 80~90 DEG C, by object
Material is squeezed into spherical shape, screens, takes the granule sealed packaging of partial size 3mm to get non-chlorine environmental-protecting type deicing salt.
Embodiment 2
According to usage ratio (mass percent) by sodium formate 35%, urea 30%, potassium acetate 25%, sodium carbonate 3%, cover
