Problems solved by technology

[0002] In coal production areas and coal storage areas, due to various climatic conditions such as wind, sun, road bumps, and low temperature in winter during the loading, unloading, and transportation of coal by various means of transportation, the coal dust of coal transportation vehicles is flying and Coal is scattered along the road. In winter, the bodies of coal transport vehicles in the north often freeze and stick to the coal, making unloading difficult. This not only causes serious environmental pollution during coal transportation and storage, but also often causes operational difficulties, and even serious loss of tons. , this phenomenon has long plagued the safe transportation and storage of coal

Abstract

The invention relates to a dustproof and antifreezing agent for coal transportation and a preparation method thereof. The dustproof and antifreezing agent consists of sodium carboxymethyl cellulose, magnesium chloride, calcium chloride, boric acid and water. The preparation method comprises the following steps: 50 percent of water is respectively added into a reaction kettle 1 and a reaction kettle 2; the sodium carboxymethyl cellulose is added into the reaction kettle 1 and is evenly stirred and dissolved to obtain solution for standby; the magnesium chloride, the calcium chloride and the boric acid are added into the reaction kettle 2 and are stirred and dissolved to obtain solution for standby; and the solutions obtained from the reaction kettle 1 and the reaction kettle 2 are added into a reaction kettle 3, are evenly stirred and mixed and are put into a container to form a finished product of the dustproof and antifreezing agent. The method has the advantages: 1. the dustproof and antifreezing agent is sprayed on the surface of a coal layer of a coal transportation vehicle to form a wet dustproof and antifreezing layer which has the functions of wind prevention, dust inhibition and jounce and spraying prevention, is sun-resistant and uncracked in summer and does not ice in cold winter; 2. in winter, the spraying of the dustproof and antifreezing agent can be enlarged to the inner wall and a base plate of an empty coal loading vehicle to form an ice-free wet isolation layer; and 3. when coal is filled, the layered spraying of the dustproof and antifreezing agent can be also enlarged to the middle between coal layers to form an antifreezing layer between the coal layers.

Description

technical field [0001] The present invention relates to a coal transportation dustproof and antifreeze agent and its preparation method, more specifically, the present invention relates to a kind of windproof, sunscreen, dustproof and antifreeze agent which is sprayed on the coal surface during the all-weather transportation of coal and its production method and how to use it. Background technique [0002] In coal production areas and coal storage areas, due to various climatic conditions such as wind, sun, road bumps, and low temperature in winter during the loading, unloading, and transportation of coal by various means of transportation, the coal dust of coal transportation vehicles is flying and Coal is scattered along the road. In winter, the bodies of coal transport vehicles in the north often freeze and stick to the coal, making unloading difficult. This not only causes serious environmental pollution during coal transportation and storage, but also often causes opera...
