Abstract

The invention discloses a good-heat-resistance rubber for a hot water bag. The good-heat-resistance rubber comprises the raw materials in parts by weight: 40-45 parts of ethylene-propylene-diene rubber, 10-15 parts of hydrogenated butadiene-acrylonitrile rubber, 2-3 parts of carbamate vulcanizing agent, 1.2-1.8 parts of sulfur, 2-4 parts of accelerant TMTD, 20-30 parts of modified white carbon black, 9-11 parts of cashew nut shell oil, 5-7 parts of boron powder, 14-15 parts of fly ash cenospheres, 14-15 parts of calcined clay, 10-12 parts of zinc oxide, 3-5 parts of quartz powder, 5-7 parts ofanti-aging agent MB, 2-4 parts of light calcium carbonate, 5-8 parts of barium stearate, 5-7 parts of palm wax, 2-4 parts of zinc diethyl dithiocarbamate and 1.5-2.5 parts of dicumyl peroxide. The invention further discloses a preparation method of the good-heat-resistance rubber for the hot water bag. The preparation method is safe, environment-friendly, simple and suitable for industrial production; and the prepared rubber has excellent heat resistance, wear resistance, anti-aging properties and elasticity and good mechanical properties.

Description

technical field [0001] The invention relates to rubber, in particular to a rubber for a hot water bag with good heat resistance and a preparation method thereof. Background technique [0002] Early rubber was latex taken from plants such as rubber trees and rubber grasses, which were processed into materials with elasticity, insulation, impermeability to water and air. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. However, the synthetic rubbers currently on the market generally have low heat resistance and cannot meet the increasing demands of the market. The hot water bag is one of the rubber products. With the improvement of people's quality of life, there is a higher demand for the heat resistance of the hot water bag. Contents of the invention [0003] Base...
