Conveyor belt repair method

Abstract

The invention relates to a conveyor belt repair method comprising the following step (1) of grinding; the step (2) of primer coating: the primer is composed of first components and second components and the mass ratio of the first components to the second components is 100:3; when the primer is coated, the first components and the second components are mixed uniformly, and the primer is coated ona polished conveyor belt with a brush; the primer is uniformly coated on the conveyor belt without missing points for forming a primer coating; the step (3) of drying; the step (4) of coating of repair agents: the repair agents are composed of components A and components B and the mass ratio of the components A to the components B is 1:1; when the repair agents are coated, the components A and thecomponents B are mixed uniformly, and then the repair agents uniformly mixed through a spray gun are uniformly coated on the primer coating; and the step (5) of curing. The conveyor belt repair method is simple in process and wide in application range, and can be widely applied to different conveyor belts; and the repair effect is good.

Description

technical field [0001] The invention belongs to the technical field of repair and relates to a method for repairing a conveyor belt. Background technique [0002] Various conveyor belts, such as PVG conveyor belts, belt conveyor belts, braided conveyor belts, etc., are very commonly used in the engineering field. However, the conveyor belt is prone to damage after being used for a period of time. Moreover, the damage of the conveyor belt is often partially damaged, and it is a pity and wasteful if it is discarded after being partially damaged. Therefore, the repair of the conveyor belt becomes extremely important. [0003] However, at present, in the repair of the conveyor belt, there are generally technical problems such as slow curing, low hardness (Shore A68±5), and low maximum bonding strength. In this way, the following problems generally exist in the conveyor belt repair process: 1. The gel time is long and the repair speed is slow; 2. The wear resistance after repa...

AI Technical Summary

Problems solved by technology

[0003] However, currently in the repair of the conveyor belt, there are technical problems such as slow curing, low hardness (Shao A68±5), and low maximum bonding strength.

In this way, the following problems generally exist in the conveyor belt repair process: 1. The gel time is long and the repair speed is slow; 2. The wear resistance after repair is poor and the service life is short; 3. The adhesion to the rubber surface is poor; 4. Low tensile strength; 5. Short elongation at break, etc.
