Problems solved by technology

[0003] The materials conveyed in the steel and cement industries generally have the characteristics of high temperature. Sometimes, the instantaneous temperature can reach 400~500°C. Therefore, the covering rubber of the conveyor belt used in this high temperature environment usually chooses B with better heat resistance. Propylene rubber; and for the core rubber of the conveyor belt, more natural rubber and styrene-butadiene rubber with better adhesion and process performance are selected. However, the disadvantage of these two rubbers is that they have poor heat resistance. When used in the environment, it is prone to degradation and aging, resulting in a decrease in the adhesion between the cloth layers and delamination of the canvas, which seriously affects the service life of the conveyor belt
At present, the high-heat-resistant conveyor belts used in the domestic cement and steel industries also generally suffer from delamination and damage between the conveyor belt canvases.

Abstract

The invention relates to high temperature resistant core glue for a conveyer belt and a preparation method of the high temperature resistant core glue, belonging to the technical field of high temperature resistant conveyer belt. The method comprises the steps of inputting ethylene propylene rubber parts into an internal mixer for banburying, inputting reinforcement padding, vulcanizing an activator, a coupling reagent, a vulkacit, a plasticizer and an anti-aging agent in an internal mixer, closing a top bolt for banburying, discharging slices after turning over, and cooling through a normal temperature fan to obtain a section of rubber compound; inputting the section of rubber compound which is cooled to the room temperature in the internal mixer, inputting a vulcanized agent and a bonding agent, discharging slices after banburying and turning over, and cooling through the normal temperature fan to obtain the high temperature resistant core glue. The high temperature resistant core glue overall considers aspects such as anti-aging performance, bonding performance and processing performance of the conveying core glue, and a formula system of the selected high temperature resistant core glue for the conveyer belt can achieve good effects. After use, the high temperature resistant core glue meets requirements for high temperature resistance in cement plants and steel mills for material conveying, prevents canvas from delaminating, the service life of the conveyer belt is prolonged greatly and the good economic benefits are achieved.

Description

technical field [0001] The invention relates to a core rubber for high heat-resistant conveyor belts and a preparation method thereof, belonging to the technical field of heat-resistant conveyor belts. Background technique [0002] With the rapid development of China's economy, it has led to the rapid growth of basic industries such as steel and cement, and the continuous expansion of market demand has prompted a rapid increase in the production scale and production capacity of the steel and cement industries. 1. Conveyor belt, the key component of material transportation in the production of cement industry, puts forward higher requirements. [0003] The materials conveyed in the steel and cement industries generally have the characteristics of high temperature. Sometimes, the instantaneous temperature can reach 400~500°C. Therefore, for the covering rubber of the conveyor belt used in this high temperature environment, B with better heat resistance is usually selected. Pr...
