Flame retardant conveying belt covering rubber formula

Abstract

The invention discloses a formula for covering rubber of a flame-retardant conveyor belt, which comprises 65-84 parts of polyvinyl chloride, 25-34 parts of nitrile rubber, 0.5-2 parts of sulfur, and dicumyl peroxide in terms of parts by weight 3‑7 parts, accelerator 1‑4 parts, nitrite 4‑9 parts, stearic acid 3‑5 parts, antiaging agent 1‑3 parts, tricresyl phosphate 40‑55 parts, butyl phthalate 10 parts ‑25 parts, 15‑25 parts of chlorinated paraffin, 15‑35 parts of zinc borate, 25‑40 parts of carbon black, 10‑14 parts of diyttrium trioxide, 2‑6 parts of antistatic agent, 2‑6 parts of zinc oxide, 25-40 parts of aluminum hydroxide, the design of the mixing ratio of the present invention is extremely reasonable, suitable for the needs of existing production and life, low cost, high labor productivity, low energy consumption in the process of processing and manufacturing, and can achieve high-yield flame retardant Formulation of conveyor belt covering rubber.

Description

technical field [0001] The invention relates to the field of preparation of flame-retardant conveyor belt covering rubber, in particular to a formulation of flame-retardant conveyor belt covering rubber. Background technique [0002] The early flame-retardant conveyor belt covering rubber was taken from the latex of flame-retardant conveyor belt covering rubber trees, flame-retardant conveyor belt covering rubber grass and other plants, and processed into materials with elasticity, insulation, impermeability and air. High elastic polymer compound. There are two types of natural flame retardant conveyor belt covering rubber and synthetic flame retardant conveyor belt covering rubber. Flame retardant conveyor belt covering rubber is processed by extracting colloids from plants such as flame retardant conveyor belt covering rubber trees and flame retardant conveyor belt covering rubber grass; synthetic flame retardant conveyor belt covering rubber is produced by polymerization...

AI Technical Summary

Problems solved by technology

The existing flame-retardant conveyor belt covering rubber mix design is unreasonable and cannot be applied to the needs of existing production and life. The cost is high, the labor productivity is low, the energy consumption is high in the processing and manufacturing process, and high production cannot be achieved.
