Abstract

The invention relates to a flame-retardant cold-resistant rubber which is prepared from the following raw materials in parts by weight: 10-100 parts of epichlorohydrin rubber, 10-50 parts of silicon rubber, 10-50 parts of polyurethane rubber, 10-60 parts of ethylene-propylene rubber, 5-30 parts of fluororubber, 2-10 parts of argil, 2-10 parts of sulfur, 1-5 parts of N,N'-diphenyl-p-phenylenediamine, 1-10 parts of silica white, 1-5 parts of aromatic oil, 1-4 parts of nano zinc oxide, 1-6 parts of zinc diethyl dithiocarbamate, 1-7 parts of 2-thioimidazoline, 1-10 parts of dioctyl phthalate and 4-12 parts of stearic acid. The rubber can effectively postpone fire and lower the flame propagation rate, has favorable cold resistance, and is suitable for continuous use under low-temperature conditions.

Description

technical field [0001] The invention relates to a flame-retardant and cold-resistant rubber, which belongs to the field of chemistry. Background technique [0002] Rubber is an elastic polymer. Rubber can be obtained from the sap of some plants, or it can be man-made. Both have quite a lot of applications and products, such as tires, gaskets, etc., and have become important economic crops. Rubber plantations are mainly concentrated in Southeast Asia, such as Thailand, Malaysia, and Indonesia. Rubber is divided into natural rubber and synthetic rubber according to raw materials. According to the shape, it can be divided into block raw rubber, latex, liquid rubber and powder rubber. Latex is a colloidal water dispersion of rubber; liquid rubber is an oligomer of rubber, which is generally a viscous liquid before vulcanization; powder rubber is processed from latex into powder to facilitate batching and processing. The thermoplastic rubber developed in the 1960s does not re...
