Abstract

The invention discloses a color master batch applicable to a polyvinylidene fluoride OK cable product. The color master batch comprises pigment, plastic additive and carrier resin; the plastic additive comprises N-N' ethylene bis stearamide, polyethylene wax and zinc stearate; the carrier resin is low molecular weight polyvinylidene fluoride; the pigment and the low molecular weight polyvinylidene fluoride are respectively 40-60% and 40-60% in percentage by weight; the pigment and the low molecular weight polyvinylidene fluoride are served as the standard to add additional 3-9% of N-N' ethylene bis stearamide, 5-12% of polyethylene wax and 2-4% of zinc stearate in percentage by weight; the preparation method comprises the steps of mixing all the materials; then kneading same in a kneading pot; finally transferring the mixed material into a twin-screw extruder of which the temperature is controlled to range from 180 to 210 DEG C for being extruded; and cooling, parching, and carrying out grain cutting, so as to obtain the color master batch as requirement. The color master batch disclosed by the invention is high in dispersibility, high in shielding capacity, high in moisture resistance, high in flame resistance, free of bleeding, resistant to move and free of color difference; and the OK cable prepared by the color master batch has the advantages of being resistant to breakdown voltage, resistant to heat and resistant to chemical corrosion.

Description

technical field [0001] The invention relates to a color masterbatch, in particular to a color masterbatch used in polyvinylidene fluoride OK cable products, and belongs to the technical field of plastic coloring. The invention also relates to a preparation method of the color masterbatch used in the polyvinylidene fluoride OK cable product. Background technique [0002] Using polyvinylidene fluoride resin to make OK cables requires different colors. Since there are few color masterbatches used in polyvinylidene fluoride resin products in the market, the existing ones mainly rely on imports, let alone OK cables in The requirements for resistance to voltage breakdown are relatively high. Ordinary coloring masterbatch processed by traditional technology, the performance of the product is not stable enough. Especially affected by its content, the pigments often fail to meet the use requirements, and the pigments are easy to migrate and bleed. Thereby the addition amount is la...
