Problems solved by technology

[0003] During the operation of the belt conveyor, if the flexibility of the idler roller is not good and the rotation resistance coefficient is high, the entire belt conveyor system will have to pay more power, consume more power, and sometimes cause the belt to tear, In the case of motor burnout, it can cause a fire in more serious cases
Due to the low value of a single roller, and the quality cannot be guaranteed after repair, almost all scrapped rollers are treated as scrap steel, resulting in great waste
In order to reduce costs and increase efficiency, some enterprises use parts of waste rollers to piece together new rollers. This method is time-consuming, laborious and wasteful, and the repair quality is unstable, so it has no promotion value.

Abstract

The invention relates to a special adhesive for steel-porcelain composite wear-resistant rollers, which is made of the following materials by weight percentage: 20-30% of epoxy resin, 5-10% of toughening agent, 2-4% of curing agent, and 5% of quartz sand -20%, silica powder 25-45%, dispersant 0-1%, coupling agent 0-2%, thixotropic agent 0-3%, reactive diluent 2-6%. The special adhesive for composite wear-resistant rollers made of the above materials has high strength, strong adhesion, good impact resistance, anti-sagging, high thixotropy, and can effectively combine steel rollers and ceramic strips to form a permanent one. The structure not only makes the roller more flexible and reliable, but also has a service life more than three times that of ordinary ceramic rollers.

Description

technical field [0001] The invention relates to an adhesive, in particular to a special adhesive for steel-ceramic composite wear-resistant rollers. Background technique [0002] The idler roller is an important part of the belt conveyor, and its main function is to support the conveyor belt and the weight of the material. The operation of the idler must be flexible and reliable. Reducing the friction between the conveyor belt and the idler plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. [0003] During the operation of the belt conveyor, if the flexibility of the idler roller is not good and the rotation resistance coefficient is high, the entire belt conveyor system will have to pay more power, consume more power, and sometimes cause the belt to tear, In the case of motor burnout, it can cause a fire in more serious cases. Due to the low value of a single roller, and the quality cannot be guaranteed a...
