Abstract
The invention discloses a novel polychloropropene cable material. The novel polychloropropene cable material is prepared from, by weight, 80 parts of polychloropropene resin with the polymerization degree of 500, 15 parts of ethyl acrylate copolymer, 15 parts of plasticizer, 5 parts of a cross-linking agent and 40 parts of filler. The invention further discloses a preparing method of the novel polychloropropene cable material. The method includes the following steps that 1, 80 parts of polychloropropene resin with the polymerization degree of 500, 15 parts of ethyl acrylate copolymer, 15 parts of plasticizer, 5 parts of the cross-linking agent, 40 parts of filler, 5 parts of stabilizer, 1 part of lubricant and 1 part of antiager are added in to a high-speed mixer in sequence and mixed uniformly under the action of the high-speed mixer; 2, the mixture is transferred to a double-screw plasticator for plastication until the mixture is plastified uniformly; 3, the mixture is pelletized after water-cooling bracing; the cable material is obtained after drying. By means of crosslinking, temperature resistance of the cable material is greatly improved, and strength and elongation performance are promoted substantially.
Description
technical field [0001] The invention relates to the technical field of composite cable materials, in particular to a novel poly(propylene chloride) cable material and a preparation method thereof. Background technique [0002] As the transmission body of energy and information, wire and cable are widely used in various fields. Most of them use plastic and rubber as insulation and sheath materials. When they are heated, melted, and decomposed, they will produce flammable gases, which will cause fires. In my country, the fire losses caused by cables alone are more than 5 billion per year. Therefore, , the flame retardant problem of wire and cable has attracted more and more attention. [0003] Polypropylene chloride material has excellent mechanical and physical properties, flexibility, chemical resistance, cheap price, and excellent processing performance, and is widely used in the production of various products. Such as shoes, daily necessities, convenience bags, etc. In ad...
