A high-strength wear-resistant and tear-resistant rubber material

Abstract

The invention discloses a high-strength wear-resistant tear-resistant rubber material which is prepared from the following raw materials in parts by weight: 40-50 parts of carboxy nitrile rubber, 20-30 parts of chloroprene rubber, 10-18 parts of natural rubber, 12-20 parts of ethylene-octylene copolymer, 5-13 parts of silane coupling agent, 1.5-2 parts of sulfur, 2-4 parts of magnesium oxide, 2-5 parts of zinc oxide, 2.5-4 parts of environment-friendly flame retardant FR-T801, 1-2 parts of antimony trioxide, 20-30 parts of carbon microsphere, 5-15 parts of nano carbon black, 20-30 parts of modified kaolin, 1-2 parts of CPE special-type stabilizer, 1.5-3 parts of stearic acid, 5-7 parts of trioctyl trimellitate and 0.5-1.5 parts of paraffin. The rubber material has the advantages of excellent wear resistance, excellent tear resistance, high strength and high toughness.

Description

technical field

[0001] The invention relates to the technical field of rubber materials, in particular to a high-strength, wear-resistant and tear-resistant rubber material. Background technique

[0002] When wire and cable products are used in special occasions such as mine mobile electrical equipment or mining flexible cables on various mining machinery, they are subject to mechanical forces in the shearing direction, which requires wire and cable sheaths to have excellent wear resistance. Tear performance. The carboxylated nitrile rubber is made of ternary copolymerization of butadiene, acrylonitrile and organic acid, referred to as XNBR. The introduction of carboxyl groups into nitrile rubber can improve its tensile strength, tear strength, hardness, abrasion resistance, adhesion and ozone aging resistance, especially the tensile strength at high temperature. The introduction of carboxyl groups can also increase the polarity of the nitrile rubber molecule and increase ...
