Preparation technique of rubber cable material

Abstract

The invention discloses a preparation technique of a rubber cable material. The preparation technique comprises the following steps that (1) after cable material raw materials are prepared according to proportion, rubber, a solid softening agent and small materials are added into an open mill in sequence, and primary mixing is conducted; (2) after primary mixing is finished, big materials, a liquid softening agent and a vulcanizing agent are added into the open mill, and secondary mixing is conducted; (3) after secondary mixing is finished, obtained mixed rubber materials are tabletted, meanwhile the tabletted rubber materials are treated with a parting agent, finally the temperature is decreased to room temperature through an air blower, and standing is conducted for 8-10 hours; and (4) the materials obtained in the step (3) are fed into a twin-screw extrusion pelletizer, and plastifying pelletizing is conducted. The preparation technique of the rubber cable material is scientific andreasonable, optimization and improvement are conducted on the basis of a traditional technique, the production efficiency of the rubber cable material can be further improved, meanwhile, the cost isreduced, the quality of the cable material is improved, and the preparation technique is suitable for mechanical operation and can bring ideal economic benefits.

Problems solved by technology

[0003] At present, the preparation of cable materials in my country mostly adopts multi-stage high-temperature internal mixing process, which has two disadvantages: First, high-temperature rubber mixing leads to serious oxidation and cracking of rubber molecular chains at high temperatures (above 140 ° C), which makes the physical and mechanical properties of rubber materials and durability. The grinding performance is obviously reduced; the second is that the multi-stage high-temperature rubber mixing process is a process of continuous heating and cooling, which wastes a lot of energy

However, although the rubber mixing with the open mill has achieved low temperature and automation, the automated process is only realized by pre-set procedures, and the rubber mixing process and effect are not necessarily optimal. There is a lack of systematic research on the control of various parameters and the detailed treatment of rubber materials, so the optimization of the preparation process cannot be guaranteed
