Abstract

The invention provides an adhesive. The invention also provides a leaking stoppage material for a coal vehicle containing the adhesive and a preparation method thereof. The leaking stoppage material comprises the following components: quick-setting cement, coal powder, and the adhesive. The adhesive and the leaking stoppage material for the coal vehicle containing the adhesive have simple and easy preparation processes, excellent adhesion performances, and waterproof properties.

Description

technical field [0001] The invention relates to an adhesive, a coal truck leakage plugging material containing the adhesive and a preparation method thereof. Background technique [0002] my country is a big country of coal production and consumption, with an annual output of more than 1.7 billion tons. Nearly 80% of the coal is transported by rail each year and sent to all parts of the country and export ports. At present, there are large gaps in the doors of coal wagons transported by railways, and there are serious leakage problems during coal transportation. According to relevant data, my country's annual loss of coal due to transportation leakage is about 10 million tons, exceeding 1% of the total output of the year. It not only causes resource and economic losses, but also brings serious dust pollution to the environment along the way. [0003] In order to solve the problem of large door gaps caused by the deformation of the carriages and the loss of coal spills caus...
