Problems solved by technology

Limited by technical means in China, nitrile-polyvinyl chloride blends with high requirements such as automobile oil pipes rely on imports. The nitrile-polyvinyl chloride blends prepared by the emulsion blending and coagulation method of the existing domestic technology have moisture There are many spots, the moisture content is not easy to control, and the glue consumption and energy consumption of the blending and coagulation device are relatively high, resulting in high production costs and problems.

Abstract

The invention discloses a technique for preparing butyronitrile-polyvinyl chloride blended rubber by a mechanical blending method, which comprises the technological processes of formulation and preparation. The technique adopts a technical proposal which adopts the mechanical blending method and corresponding formulation and preparation process to prepare butyronitrile-polyvinyl chloride blended rubber. The technique overcomes the disadvantages of butyronitrile-polyvinyl chloride blended rubber product prepared by an emulsion blending coacervation method in the prior art including poor quality and high cost; moreover, the technique realizes the preparation of butyronitrile-polyvinyl chloride blended rubber by the mechanical method instead of the coacervation method and reaches the aims offeasible technique, up-to-standard quality, energy saving and consumption reduction and production cost reduction.

Description

technical field [0001] The invention relates to a preparation technology of blended rubber, specifically refers to a mechanical blending method for preparing a nitrile-polyvinyl chloride blend by blending nitrile rubber and polyvinyl chloride resin by a mechanical blending method Nitrile-PVC blend technology. Background technique [0002] Nitrile-polyvinyl chloride blend rubber is made by blending nitrile rubber with polyvinyl chloride resin. It is widely used in automobile oil pipes, wire and cable sheaths, seals, and oil-resistant conveyor belts. The preparation of the nitrile-polyvinyl chloride blend rubber in the prior art adopts the emulsion blending coagulation method, that is, two kinds of latex are mixed according to the required ratio and then obtained through coagulation, washing, drying, heat treatment and other processes. Limited by technical means in China, nitrile-polyvinyl chloride blends with high requirements such as automobile oil pipes rely on imports. Th...
