Problems solved by technology

[0002] Inner Mongolia is a large coal-producing province, and the task of coal transportation is heavy. During the transportation of coal, there will be safety, cargo damage and dust problems. The proportion of losses on the way is as high as 1% to 3%; ②During the coal transportation of the train, there is a large amount of pulverized coal dust, which is suspended in the air, causing great pollution to people’s breathing and the surrounding environment; ③When the train passes through the tunnel, the Affected by high-speed airflow, coal powder is blown out of the vehicle, and the long-term accumulation increases the concentration, which is suffocating and seriously affects the health of railway workers and the normal operation of equipment in the cave.
[0003] In order to solve the problem of dust in the process of coal transportation, some use the mechanical cover method, which is to add a cover to each car body, which can effectively prevent coal dust pollution, but the cost is high and the effective load is low
In addition, a series of actions such as the switch cover, switch position and opening direction will have an impact on the existing mechanized coal loading and unloading process, which is difficult to match with the existing automated production line
Some use tarpaulin covering method, which is commonly used in automobile transportation, but in the case of high degree of automation in railway transportation, large traffic volume, and fast operation speed, it requires a lot of manpower (according to calculations, each car needs 4 to 5 At the same time, tarpaulin covering and withdrawal are slow and difficult to implement, which affects the efficiency of coal transportation, and the cost is too high; there are also chemical dust suppression methods, but most of them are costly and complicated, and require heating equipment. Limiting its promotion in practical application
[0004] Also have a kind of patent application number to be 2007100173547 fugitive dust suppression agent at present, the raw material that it adopts is carboxy cellulose sodium etc., because of its raw material is difficult to dissolve at normal temperature, needs to be prepared at high temperature, so just invisibly increased production dust suppression The cost of dust agent, and its production process is complex

Abstract

The invention discloses a dust-raise preventing spray covering bonding agent on the surface of a unit train and a preparation method thereof. The bonding agent comprises sodium carboxymethylcellulose, pre-gelatinized starch, sodium benzoate and water. The preparation method comprises the following steps of: pre-adding the tap water into a stirring pot at the normal temperature, and adding and stirring the sodium carboxymethylcellulose, the pre-gelatinized starch and the sodium benzoate respectively until the sodium carboxymethylcellulose, the pre-gelatinized starch and the sodium benzoate are completely dissolved to obtain the finished product. The bonding agent has the advantages of low cost, production process finished at the normal temperature, no special requirement, simple and convenient process, long storage time, independent components and solution thereof without any toxic or side effect and corrosiveness, no secondary pollution and remarkable dustproof effect.

Description

technical field [0001] The invention relates to a dust suppressant and a preparation method thereof, in particular to an anti-dust spray covering adhesive on the surface of a coal transport train and a preparation method thereof.
