Abstract

The invention relates to a preparation method for a basalt fiber conveying belt, and belongs to the technical field of rubber products. The preparation method comprises the following steps: performing hydrochloric acid treatment, coupling agent treatment and plasma grafting and impregnation treatment on basalt fiber cloth; mixing natural rubber, synthesized rubber, an activating agent, an anti-aging agent, a reinforcement agent and a plasticizer to obtain a first section of mixed rubber; adding a promoter and a vulcanizer for mixing to obtain a second section of mixed rubber, and extruding the second section of mixed rubber to obtain a coverage rubber sheet; mixing the natural rubber, the synthesized rubber, the activating agent, the anti-aging agent, an adhesive, the reinforcement agent and the plasticizer to obtain a first section of mixed rubber; then adding the promoter, the vulcanizer and an adhesive RA for mixing to obtain a second section of mixed rubber, freshening after the second section of mixed rubber is stewed, and attaching the second section of mixed rubber and the basalt fiber cloth to obtain rubberized canvas; attaching the basalt fiber rubberized canvas layer by layer to obtain a framework, attaching the coverage rubber sheets to the upper surface and the lower surface of the framework to obtain a belt blank, and vulcanizing the belt blank to obtain the basalt fiber conveying belt. The conveying belt prepared by the preparation method is low in cost, light in mass, high in intensity, fatigue-resistant and long in service life; the conveying energy consumption can be greatly reduced.

Description

Technical field [0001] The invention relates to a preparation method of a basalt fiber conveyor belt, in particular to a conveyor belt suitable for long-distance material transportation in industries such as coal mines, metallurgy, mining, etc., and belongs to the technical field of rubber products. Background technique [0002] Rubber conveyor belts are the second most important rubber products after tires. They are mainly used in coal, metallurgy, building materials, mining, ports and other industrial fields. The annual growth rate of demand exceeds 25%. [0003] Conveyor belt is mainly composed of upper and lower covering rubber and skeleton material, and the skeleton material can generally be divided into fabric and steel wire rope. Because of its high strength, steel cord conveyor belts are widely used in long-distance and large-volume mining areas. However, the horizontal spacing of steel cords makes them easy to tear. The metal skeleton material makes the belt weight general...
