Abstract

The invention discloses a preparation technology of an environment-friendly butyronitrile/polyvinyl chloride blend rubber. The preparation technology comprises a formulation process flow and a preparation process flow. In the preparation technology, environment-friendly epoxy soybean oil is employed to replace a lead sulfate tribasic stabilizer in the prior art, and the preparation technology is provided with a corresponding formula and a technical scheme of the preparation process, thus avoiding problems of being toxic, harmful and not environment-friendly and not satisfying ELV directive requirements in the prior art. Oil resistant rubber products made of the environment-friendly butyronitrile/polyvinyl chloride blend rubber which is prepared by the preparation technology achieve the purposes of being nontoxic, nonharmful, environment-friendly and satisfying the ELV directive requirements while satisfying various mechanical strength indexes, physical and chemical indexes.

Description

technical field [0001] The invention relates to the preparation of an oil-resistant rubber, in particular to the preparation technology of an environment-friendly nitrile / polyvinyl chloride blended rubber which uses an environment-friendly stabilizer to manufacture oil-resistant rubber products such as automobile oil pipes. Background technique [0002] Nitrile / polyvinyl chloride blended rubber, also known as oil-resistant rubber, is widely used in the manufacture of oil-resistant rubber products such as automobile oil pipes and oil delivery rubber hoses. The stabilizer of the nitrile / polyvinyl chloride blended rubber of the prior art is lead sulfate tribasic, and lead sulfate tribasic contains the harmful substance "lead" banned in the ELV directive, so there are poisonous, harmful, not environmentally friendly and unhealthy Issues with compliance with the requirements of the ELV Directive. Contents of the invention [0003] Aiming at the problems and deficiencies in the...
