Cold-resistant rubber material for sheath wire and manufacturing method of cold-resistant rubber material for sheath wire

Abstract

The invention discloses a cold-resistant rubber material for a sheath wire and a manufacturing method of the cold-resistant rubber material for the sheath wire. The manufacturing method provided by the invention comprises the following steps: sequentially performing banburying, mixing, cooling, toning tabletting and cooling after mixing CPE (chlorinated polyethylene) 135B, magnesium oxide, 512 EPDM (ethylene-propylene-diene monomer), antimonous oxide, paraffin wax, talcum powder, N550 black smoke, CPE special stabilizer, antioxidant RD, JXB05-1 white carbon black, antioxidant 1010, environment-friendly fire retardant FR-T801, dioctyl sebacate, triallyl isocyanurate and LH-C96 vulcanizer, and finally obtaining the rubber material for the sheath wire by secondary mixing, secondary mixing, secondary cooling and secondary cooling. According to the invention, the cold-resistant rubber material for the sheath wire has a cold-resistant low temperature property higher than national standard, CCC (China compulsory certification) standard and VDE (verband deutscher elektrotechniker) standard and has a simple manufacturing method and obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to a cold-resistant and environment-friendly rubber material for a sheath wire and a preparation method thereof. Background technique [0002] Sheathed wires are much safer than ordinary wires and have a wide range of applications in the construction field. However, due to the widespread use of polymer crystalline materials with plastic properties such as polyethylene or polyurethane, the sheathed wires are continuous under outdoor conditions. When in use, due to the low temperature environment in nature, it will cause problems such as aging, brittleness, and cracking. At the same time, it will easily lead to a significant decrease in physical and mechanical properties after being corroded under acid and alkali conditions, thereby reducing the service life of the cable. Contents of the invention [0003] The purpose of the present invention is to provide a kind...
