Medical stone powder filler for cables and preparation method thereof

Abstract

The invention relates to a medical stone powder filler for cables. The medical stone powder filler is prepared from the following raw materials in parts by weight: 2-3 parts of vinyl acetate resin emulsions, 1-2 parts of 3-aminopropyl triethoxysilane, 0.2-0.3 part of tallow seed oil, 2-3 parts of barium oxide, 2-3 parts of N-phenyl-2-naphthylamine, 0.2-0.3 part of sodium percarbonate, 0.4-0.5 parts of PVC (Polyvinyl Chloride) paste resin, 0.2-0.3 part of triaryl phosphate, 0.3-0.5 parts of distearyl thiodipropionate, 75-80 parts of medical stone powder, a right amount of water, a right amount of 4%-6% hydrochloric acid and 10-15 parts of auxiliary agents. Medical stone powder is used in the filler disclosed by the invention; according to the filler, good surface hydrophobicity is achieved by carrying out organic modification on the surface, good reinforcing property is achieved due to the increase of compatibility with a cable material, and the toughness and tensile strength of the cable material can be enhanced; the cable material has the characteristics of flame resistance, acid and alkali resistance, microbial resistance and abrasion resistance due to the addition of the PVC paste resin; and the auxiliary agents can enhance the dispersity of the filler.

Description

technical field [0001] The invention belongs to the field of cable sheathing materials, in particular to a medical stone powder filler for cables and a preparation method thereof. Background technique [0002] The cable outer sheath is a structural part that protects the insulation layer of the wire and cable from environmental factors. Cable materials include rubber, plastic, nylon and other varieties, all of which have their own excellent characteristics. Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagent resistance, high tensile strength, elongation and reversible crystallinity, bonding Good performance, aging resistance, heat resistance, oil resistance, chemical corrosion resistance, can be used for a long time at 80 ~ 100 ℃, has a certain flame retardancy; but also has disadvantages, such as poor storage stability, and with the cable...
