Problems solved by technology

[0003] At present, the application of rubber-type chlorinated polyethylene (CM) is mainly to use the material after direct cross-linking in the fields of wire and cable, rubber hose, conveyor belt, rubber dam, automobile inner tube, elevator handrail, etc. If rubber-type chlorine If chemical polyethylene (CM) is used in the foaming field, it is necessary to add plasticizers before it can be used for direct foaming processing, and the increase of plasticizers will cause environmental pollution, which is not in line with the concept of industrial environmental protection production. Therefore, rubber There is no relevant report on the application of type chlorinated polyethylene (CM) in the field of foaming technology

Abstract

The invention discloses a rubber type chlorinated polyethylene foam material mainly prepared from raw materials in parts by weight as follows: 80-100 parts of chlorinated polyethylene, 10-40 parts of filler, 2-6 parts of a foaming agent, 0.5-1.0 part of a crosslinking agent, 1.2-2.0 parts of a lubricant and 1.0-2.0 parts of a stabilizer; chlorinated polyethylene is rubber type chlorinated polyethylene with the chlorine mass fraction being 36 plus / minus 1%, the Mooney viscosity being 45-75 (ML125 DEG C1+4) and the Shore hardness being 50-60 HA. Compared with the prior art, the rubber type chlorinated polyethylene can be applied to the foam field, direct foam processing of chlorinated polyethylene can be realized without addition of a plasticizer, the environment-friendly and non-toxic characteristics of the rubber type chlorinated polyethylene foam material are guaranteed, and the rubber type chlorinated polyethylene foam material has good mechanical properties, good softness, small permanent deformation, excellent weather resistance, chemical resistance and damping performance and can be used for replacing traditional PVC (polyvinyl chloride) foam materials to be applied to the damping field.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a rubber-type chlorinated polyethylene foam material and a preparation method thereof. Background technique [0002] Chlorinated polyethylene is a chlorinated polymer obtained by chlorination of high-density polyethylene. According to its chlorine content, residual crystallinity and other characteristics, it can be divided into resin type chlorinated polyethylene (CPE) and rubber Type Chlorinated Polyethylene (CM). Among them, the resin-type chlorinated polyethylene (CPE) contains a certain amount of residual crystals in the structure, and the rubber-type chlorinated polyethylene (CM) basically does not contain residual crystals. The rubber-type chlorinated polyethylene (CM) is a new type, Environmentally friendly special rubber, which has better cold resistance, aging resistance, ozone resistance, oil resistance, and flame resistance than other rubbers. The service temperature ...
