Novel cold-resistant oil-resistant flame-retardant antistatic conveyor belt

Abstract

The invention discloses a novel cold-resistant oil-resistant flame-retardant antistatic conveyor belt. The belt comprises an upper rubber covering layer, a lower rubber covering layer and a frameworklayer, wherein an anti-skid convex strip is arranged on the upper surface of the upper rubber covering layer, the upper rubber covering layer and the anti-skid convex strip are integrally formed, theframework layer is positioned between the upper rubber covering layer and the lower rubber covering layer, the framework layer is mainly composed of bonding core glues and steel wire nets, the steel wire nets are uniformly distributed between the adhesive core glues, the anti-skid convex strip is in a ladder shape, and the steel wire nets are formed by interweaving transverse steel wire ropes andlongitudinal steel wire ropes. The conveyor belt has better physical and mechanical performance and better appearance quality of semi-finished products and finished products, the cold resistance, oilresistance and flame retardant performance of the conveyor belt are improved, in a using process, the slipping phenomenon between conveyed objects and the conveyor belt is overcome, meanwhile, the antistatic performance of the conveyor belt is improved by using the antistatic property of 70% chlorinated paraffin.

Description

technical field [0001] The invention relates to the technical field of rubber conveyor belts, and more specifically relates to a cold-resistant, oil-resistant, flame-retardant and antistatic conveyor belt. Background technique [0002] Conveyor belts are indispensable components in modern industrial production, especially rubber conveyor belts are widely used due to their price and performance advantages. [0003] But the rubber conveyor belt also has obvious defects, such as: it is easy to harden in cold environment and accelerates aging; it is easy to dissolve in oil, the strength is reduced, and it is easy to generate static electricity, which has hidden dangers. Especially in some specific occasions, it is difficult to achieve the conveyor belt with cold resistance, oil resistance and antistatic properties at the same time in the prior art. [0004] At present, the best cold-resistant rubber in general-purpose rubber is cis-butadiene BR9000 rubber, and the best oil-resi...

Problems solved by technology

[0005] However, the compatibility of the two rubbers, cis-butadiene BR9000 rubber and nitrile rubber, is not good. In the process, slippage often occurs between the conveyed object and the conveyor belt;

[0006] Antistatic in the prior art is generally achieved by adding a conductive agent. However, in rubber products, the conductive agent generally has the problem of not being durable, and if used for a long time, the degree of danger will increase.

[0007] Another solution is to install conductive materials connecting the two sides of the conveyor belt body, especially conductive fibers, but how to fix the conductive fibers is difficult to solve. It is easy to cause peeling if it is installed on the surface, and it is easy to cause damage if it is buried in the belt body. Grease enters the belt body along the junction of the fiber and the conveyor belt, breaking through the grease-proof layer on the surface of the belt body
