Abstract

The invention relates to a novel chlorinated polyethylene rubber compound material, in particular to a novel chlorinated polyethylene rubber compound material for preparing sealing strips and a methodfor preparing the novel chlorinated polyethylene rubber compound material. The novel chlorinated polyethylene rubber compound material comprises, by weight, 100 parts of rubber-based chlorinated polyethylene, 7-10 parts of magnesium hydroxide, 35-40 parts of semi-reinforced 774 carbon black, 60-70 parts of 990 carbon black, 0.5-1 part of stearic acid, 2-3 parts of calcium stearate, 15-20 parts ofkaolin E2, 25-32 parts of dioctyl terephthalate, 4-6 parts of antimony trioxide, 0.5-1 part of protection wax and 4.5-5.5 parts of vulcanizing agents ECHOS 808 3M-50. The novel chlorinated polyethylene rubber compound material and the method have the advantage that the novel chlorinated polyethylene rubber compound material is excellent in ageing resistance, ozone resistance, flame retardance andmechanical property and low in cost and can be used for preparing the flame-retardant building sealing strips. The invention further provides a method for preparing the sealing strips.

Description

technical field

[0001] The invention relates to a new composite material of chlorinated polyethylene rubber, more specifically, to a new composite material of chlorinated polyethylene used for preparing sealing strips and a preparation method thereof. Background technique

[0002] Chlorinated polyethylene is an important polymer material prepared by chlorine substitution reaction of polyethylene, and can also be regarded as a terpolymer of ethylene, vinyl chloride and 1,2-dichloroethylene. According to its properties and uses, it can be divided into two categories: resin type products (CPE) and rubber type products (CM rubber). The former has higher relative molecular weight, mechanical strength, melting temperature and plasticizing temperature, and is mainly used for general purpose. Resin PVC, ABS, PP, PE and other weather resistance and impact modifiers; the latter has moderate mechanical strength and flexibility, low melt viscosity and plasticizing temperature, and is ma...
