Rubber open mixing process for rubber cable material

Abstract

The invention discloses a rubber open mixing process for a rubber cable material. The process comprises the following steps of (1) preparing rubber raw materials and a compounding agent according to parts by weight; (2) adding a proper amount of the rubber raw materials into the open mill, softening the rubber raw materials, wrapping a roller, and keeping a proper amount of accumulated rubber at the upper end of a roller gap; (3) gradually adding the compounding agent into the open mill for mixing after roller wrapping; and (4) plasticizing and granulating a mixed rubber material to obtain thefinished cable material. According to the rubber open mixing process for the rubber cable material, the process is improved on the basis that an existing rubber cable material is prepared by a traditional open mill, so that the requirement of high quality is met while keeping high production efficiency of the rubber cable material in a preparation process; and meanwhile, the whole process is simple and easy to understand, and the rubber cable material is suitable for large-scale processing and use in factories.

Description

technical field [0001] The invention belongs to the technical field of rubber processing, and in particular relates to a rubber cable material kneading process. Background technique [0002] Cable material is a general term for plastics used for wire and cable insulation and sheathing. It is made of rubber, plastic, nylon and other materials as base materials, combined with auxiliary components such as plasticizers, fillers, color masterbatches, and antioxidants. Among them, rubber cable materials account for a considerable proportion. Although the production volume of rubber cable materials in my country is huge, the grades of its manufactured products are not high, the product quality uniformity and stability are poor, the production efficiency is low, and the energy consumption is high. The main reason is that the advanced core technology of rubber processing has not been fully mastered, and the research on rubber processing theory and methods is still relatively backward...

Problems solved by technology

At present, in the above process, there is a lack of systematic research. Usually, the operation of rubber in the mill is realized through manual control, operating experience and incomplete operation manuals. Therefore, different operators and operations at different stages During the process, the processing time, temperature and other parameters often change with the change of personal experience, which can easily cause the plasticity of the rubber material to be too low or too high, and the phenomenon of uneven dispersion of compounding agents, scorching, and blooming will occur, which will make the subsequent The rolling, extrusion, vulcanization and other processes cannot be carried out normally, and the physical or mechanical properties of the product are unstable or degraded, resulting in production quality that cannot be guaranteed
