Problems solved by technology

At present, most of the cold patching process is to polish the new surface of the belt first, then apply a layer of primer to activate the rubber surface, and then pour polyurethane glue after the primer is dry. Repair time, and reduce work efficiency, and because the primer contains a lot of flammable solvents, it also brings harm to the human body and the environment, and there are potential safety hazards

Description

technical field [0001] The invention relates to the field of cold patch glue, in particular to an environment-friendly and high-efficiency cold patch glue and a preparation method thereof. Background technique [0002] Conveyor belts are widely used in coking plants, power plants, gas plants, cement plants, mines and other enterprises. As a continuous conveying machine, the belt conveyor generally consists of multiple belt conveyors connected to each other to form a transportation line, that is, the upstream belt conveyor transfers the material conveyance to the downstream belt conveyor, and there is a strong correlation between them. If one of the belt conveyors A failure will cause the belt conveyor of the entire system to lose its transportation function, resulting in the shutdown of the entire production line and huge losses. As a belt conveyor system for conveying coke, coal and other materials, the materials often contain impurities such as metals and hard lumps, whic...
