Abstract
The invention relates to an environmentally-friendly composite type snow-melting agent and a preparation method thereof. The snow-melting agent is prepared from the following raw materials in parts by weight: 40 to 55 parts of chlorine salt, 45 to 55 parts of organic salt and 1 to 2 parts of a corrosion inhibitor, wherein the chlorine salt is prepared from the following raw materials in parts by weight: 15 to 20 parts of potassium chloride and 25 to 35 parts of ammonia chloride; the organic salt is prepared from the following raw materials in parts by weight: 25 to 30 parts of potassium acetate and 20 to 25 parts of urea; the corrosion inhibitor is one of or a mixture of sodium nitrite and sodium phosphate; and the snow-melting agent is prepared from the following raw materials in parts by weight: 50 parts of chlorine salt, 48 parts of organic salt and 2 parts of a corrosion inhibitor. The snow-melting agent is doped with the corrosion inhibitor; and related corrosiveness tests indicate that the snow-melting agent doped with the sodium phosphate has smallest corrosion effect on metal and can protect the surface of the metal, the metal still can maintain the original metal luster when being soaked into a salt solution, and a good metal corrosion-resistant effect is achieved.
Description
Technical field
The invention belongs to pavement snow melting Material Field, and in particular to a kind of environment-friendly composite Snow Agent and preparation method thereof.
Background technology
At present Snow Agent both domestic and external is roughly divided into inorganic salts Snow Agent, organic salt Snow Agent and compound snow-melting agent, nothing
Based on villaumite, preferably, economy is superior for Thaw performance for machine salt Snow Agent, but through Long-Time Service it is found that currently using
Snow Agent have many harm.
A large amount of salt Snow Agents be used to process road snow, and after causing snow melt, snow-broth salinity is too high.Vehicle is travelled
Salt solution splashing or Snow Agent is caused directly to be applied to when shedding on vegetation and upper soll layer, salinity gathers, it may occur that salt stress
Harm, is the pressure increase of plant cell exosmosis, and the moisture in plant is captured by high concentration salt solutions, damages the epidermal tissue of plant
And root system, and the beginning of spring in the coming year be plant can not normal germinating growth, while a large amount of salinities can cause plant by plant intake
Interior various hormones or enzyme content are lacked of proper care, and affect the eubolism of plant.It is nearer that this kind of situation is embodied in concrete road
Plant wilt or death, then do not affect normal growth apart from road plant farther out.Another kind of situation is containing more salty
The accumulated snow for dividing is stacked into vegetation root by concentration, causes local salinity too high, can also cause above-mentioned consequence.
Snow Agent can cause corrosiveness to the metal of road both sides, be to mitigate Snow Agent to act on corrosion of metal, and one
As a small amount of corrosion inhibiter is added in Snow Agent, with protect metal occur oxidation reaction cause corrosion.
At present the Snow Agent species of research is various, but being promoted on a large scale without a kind of environment friendly type snow melt agent makes
With the research work of Snow Agent is far from terminating.
