Abstract

An SBR diving material and the preparation method relate to a preparation method of diving materials; the method is characterized in that based on 100kg of synthetic rubber and on the original formula, 20 to 29kg of EPDM is added, followed by the procedures of internal mixing, open mixing, cooling, and open mixing again, film setting, cold pressing and foam molding. The material has the advantages that EPDM has superior anti-ozone and anti-erosion ability, and the chemical properties of EPDM enable good curing properties of EPDM and the lowest proportion among all the rubbers; besides, EPDM can absorb a plurality of fillers and oils and has little impact on the properties. Therefore, adding EPDM into the raw material can well improve the contractility, flexibility, anti-oxidation and corrosion-resistant capabilities of SBR.

Description

Technical field: [0001] The invention relates to a method for preparing diving materials. Background technique: [0002] Synthetic rubber materials are widely used in sports and fitness, water sports, and water rescue activities. The main raw materials of traditional SBR diving materials are natural rubber and styrene-butadiene rubber, which are formed after high-temperature and high-pressure foaming after mixing with special substances. Domestic SBR generally has excessive flammability and transfer elements such as soluble lead, and large shrinkage. Insufficient elasticity, oxidation resistance and other shortcomings. Usually, the formula of synthetic rubber is based on 100kg of synthetic rubber, 81-83kg of American clay, 70-74kg of compatibilizer, 53-55kg of softener, 26-26.3kg of reinforcing filler, and 15-8kg of processing aid are added by weight. 16kg, vulcanizing agent 2~2.5kg, activator 5.2~5.5kg, dispersant 3~4kg, foaming agent 6~6.5kg, foaming aid 6~6.5kg.
