Problems solved by technology

[0004] Although the above-mentioned flame-retardant rubber materials have relatively moderate mechanical properties and flame-retardant properties, especially excellent flame-retardant properties, there are still some problems: polyvinyl chloride is a plastic product, although polyvinyl chloride and nitrile rubber are often blended The covering layer is made of rubber material, but its toughness and softness are still inferior to rubber materials, and the conveyor belt is easy to slip, deviate, and has poor flexibility; neoprene is used as the covering layer rubber material, which has poor processing performance and is easy to stick to the roller. , easy to scorch, and difficult to control the process during pr

Abstract

The invention relates to high-strength laminated fire-retarding conveyer belt coating rubber and a preparation method thereof. The rubber has both high fire retardance and mechanical strength, and can be used as fire-retarding conveyer belt coating rubber. According to the method, substrate rubber is masticated in a double-roll open mill; stearic acid, an anti-aging agent, a fire retardant, metal oxide, a reinforcing agent, a vulcanization accelerator and a vulcanizing agent are added to the substrate sequentially; the mixture is uniformly mixed in the open mill, such that coating gum is obtained; the coating gum and a bonding layer are vulcanized on a molding vulcanization plate, such that a high-strength laminated fire-retarding conveyer belt coating rubber product is obtained. According to the invention, styrene butadiene rubber, natural rubber, cis-1,4-polybutadiene rubber or a mixture of the three is adopted as the substrate rubber. Compared to a traditional coating material, mechanical strength, flexibility and processing property of the coating rubber are improved, and cost is reduced.

Description

technical field [0001] The invention relates to a high-strength laminated flame-retardant conveyor belt covering layer rubber and a preparation method thereof, which has high flame-retardant performance and mechanical strength and can be used for the flame-retardant conveyor belt covering layer rubber. Background technique [0002] The conveyor belt is the main tool for transporting materials on the ground and transporting coal underground in coal mines. Since the traditional rubber conveyor belt is flammable, the material structure strength of the conveyor belt will drop sharply in case of fire and strong heat radiation, and the components will collapse. The conveyor belt has repeatedly caused major fire accidents and cannot meet the requirements of flame retardancy. The belt material must have flame retardant properties [Special Rubber Products, 2007, 28(5): 47-52]. [0003] After years of research and development, various countries in the world have formed a situation wh...
