TCR thermo-controllable macromolecular elastic compounded rubber material

Abstract

The invention discloses a TCR thermo-controllable macromolecular elastic compounded rubber material. The material is prepared from the following raw materials in parts by weight: 60-70 parts of rubber materials, 15-20 parts of olefin block copolymer, 20-30 parts of injection materials, 5-10 parts of ethylene-octylene copolymer, 4-6 parts of foaming agent, 0.3-2 parts of vulcanizing agent, 0.3-2 parts of accelerant, rubber auxiliaries, a filling agent and an active agent, wherein the weight parts of rubber auxiliaries account for 1%-3% of that of rubber materials, the weight parts of filling agent account for 5-15% of that of the rubber materials, and the weight parts of active agent account for 3%-5% of that of the rubber materials.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a TCR thermally controllable polymer elastic composite rubber material. Background technique [0002] EPDM is ethylene propylene diene monomer, which belongs to the polyolefin family, so it has excellent vulcanization. Among all rubbers, EPDM has the smallest proportion and is widely used in various fields. However, in production, the viscosity of EPDM material increases due to the increase in dosage, which cannot ensure the smooth progress of injection molding and injection processes, and has the disadvantages of wear resistance and poor anti-slip effect, which limits the scope of its processing application. [0003] The Chinese patent publication number is CN 101747564 B, the subject of which is an invention patent of a high-flow EPDM material and its preparation method, which uses its formula and preparation process to modify EPDM so that its fluidity meets the requirements ...
