Preparation technology for conductive rubber strips

Abstract

A disclosed preparation technology for conductive rubber strips comprises the following steps: a, putting vulcanized rubber, a promoter and an antiaging agent into a rubber mixing mill according to mass percentages for mixing, performing mixing for 25-45 min, after uniformly mixing, adding a conductive material, and performing mixing again for 10 min, so as to obtain a uniformly-mixed rubber material; b, respectively putting zinc oxide and carbon fiber into the above obtained rubber material for mixing, performing mixing for 20 min, so as to obtain a conductive rubber material; and c, putting the above obtained conductive rubber material into a double screw extruder for extrusion moulding with the working temperature of 150-250 DEG C, performing vacuum forming and water cooling to form conductive rubber, and then employing a cutting machine to cut conductive rubber into conductive rubber strips. The preparation technology is simple in operation, high in work efficiency and reduced in cost, also the tension performance and the elasticity of rubber are increased, and the conductive performance of the conductive rubber is further improved by adding carbon fiber.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to a preparation process of a conductive rubber strip. Background technique [0002] As one of the composite conductive polymer materials, conductive rubber is made of rubber elastomer as the matrix and conductive filler, which not only retains the elasticity of the matrix rubber, but also has the conductivity of the conductive filler. Because the material can adjust the electrical and mechanical properties of the material according to the requirements of use in a wide range, and has the advantages of light weight, easy processing, low cost, and mature technology, it has developed rapidly in recent years and has become a new type of functional material. Materials are widely used in aerospace, aircraft manufacturing and machinery manufacturing, medicine, electrical and electronic industries. In recent years, with the development of the electronics industry, conductive rubber has begun...

However, the material cost of making conductive rubber is high, and the conductivity is not ideal

[0003] Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is that it can be used in a wide temperature range, which can be used at -60°C (or lower temperature) to +250°C. ℃ (or higher temperature), but the mechanical properties of silicone rubber such as tensile strength and tear strength are poor. In addition, the general silicone rubber has poor oil resistance and solvent resistance, so silicone rubber is not suitable for ordinary conditions, but it is very suitable for many specific occasions
