Abstract

The invention discloses a production technique of a conductive nano flame-retardant rubber sheet, which comprises the following steps: A. proportioning: mixing 65 parts by mass of silicone rubber, 35 parts by mass of copper powder, 10 parts by mass of zinc oxide, 2 parts by mass of sulfur, 5 parts by mass of stearic acid, 2.5 parts by mass of anti-aging agent and 2.5 parts by mass of anti-scorching agent together to form a conductive rubber mixture, wherein the temperature of the conductive rubber mixture is controlled at 50-90 DEG C; B. cutting; C. calendering; D. stretching; E. coating; F. heating and cooling; and G. carrying out die cutting. According to the production technique, the multiple raw materials are subjected to cutting, calendering, stretching, coating, heating, cooling, die cutting and the like to form the conductive rubber sheet while controlling the thickness at 1-3mm, so that the die cutting efficiency is enhanced, and the defective rate of the finished product is lower; and the whole production technique has the advantages of high degree of automation, low labor intensity and high production efficiency.

Description

Technical field: [0001] The invention relates to a production process, in particular to a production process of a conductive nano flame-retardant rubber sheet, which belongs to the technical field of rubber. [0002] Background technique: [0003] Conductive rubber is to uniformly distribute conductive particles such as glass silver plating, aluminum silver plating, and silver in silicone rubber, and make the conductive particles contact through pressure to achieve good electrical conductivity. There are military and commercial applications. Its main function is sealing and electromagnetic shielding. Products can be molded or extruded and are available in sheet or other die-cut shapes. [0004] The existing conductive rubber sheets are generally made by manual cutting, which not only increases the labor intensity of the staff, but also has low production efficiency, which virtually increases the production cost. higher. Invention content: [0005] The purpose of the ...
