Problems solved by technology

[0003] At present, in the production process of polyolefin cable materials, most of the granulation methods of grinding surface eager cutting and water ring granulation are adopted. The by-products produced by these granulation methods account for a large proportion, about 1-2.5%. Client use, directly reduce product net profit

Abstract

The invention discloses an anti-stick polyolefin cable material preparation method, which comprises: S1, adding an ethylene-octene copolymer, an ethylene-vinyl acetate copolymer, FX-5924, silicone, glyceryl palmitostearate, nanometer magnesium silicate, an antioxidant and a light stabilizer to a mixer, carrying out mixing plasticizing, conveying into a screw extruder through double cone shearing,extruding, and carrying out water tension strip granulation to obtain a material B; S2, adding an ethylene-octene copolymer, an ethylene-vinyl acetate copolymer, a maleic anhydride grafted ethylene-octene copolymer, maleic anhydride grafted polyethylene, aluminum hydroxide, magnesium hydroxide, sodium isethionate, trimethylolpropane trimethacrylate and succinimide to a mixer, and uniformly mixingto obtain a material A; and S3, uniformly mixing the material A and the material B, mixing, and granulating. According to the present invention, the prepared cable material has characteristics of goodanti-stick performance and less granulation by-products, and can effectively avoid the sticking to the wire core in the application in cable sheathing layers.

Description

technical field [0001] The invention relates to the field of cables, in particular to a preparation method of an anti-adhesion polyolefin cable material. Background technique [0002] The polyolefin cable material cross-linked by electron beam radiation not only inherits the excellent characteristics of polyolefin such as low relative density, good chemical resistance and water resistance, good mechanical strength, electrical insulation, low smoke and zero halogen, etc. Through irradiation, its molecular chain becomes a network structure, which greatly improves the mechanical properties, heat resistance and crack resistance, and improves the environmental aging resistance, which has a very large application prospect. [0003] At present, in the production process of polyolefin cable materials, most of the granulation methods of grinding surface eager cutting and water ring granulation are adopted. The by-products produced by these granulation methods account for a large prop...
