Embodiment 1

[0017] Color masterbatch used to prepare red polyvinylidene fluoride OK line products:

[0018] First weigh the materials according to the following proportions for pre-mixing:

[0019]

[0020] The above units are g.

[0021] Then put the above-mentioned mixture in a kneading pot with a current control of 35A and mix it at high speed until it is coated, and then put the uniformly stirred mixture into a twin-screw extruder whose main machine temperature is controlled at about 200°C to extrude. After cooling, Dried and granulated to make the required masterbatch.

Embodiment 2

[0023] Color masterbatch used to prepare red polyvinylidene fluoride OK line products:

[0024] First weigh the materials according to the following proportions for pre-mixing:

Abstract

The invention provides color master batches for a polyvinylidene fluoride OK cable. The color master batches consist of a pigment, a plastic auxiliary agent and carrier resin, wherein the plastic auxiliary agent contains N-N' aethylenum di-octadecanamide, polyethylene wax, zinc stearate, an antistatic agent and a high-grade composite lubricant. The preparation method comprises the following steps of: mixing the materials according to the formula; kneading the materials in a kneading pot at a high speed; and putting the uniformly stirred mixture into a double-screw extruder of which the host temperature is controlled to be between 180 and 210 DEG C, and extruding the mixture; cooling, drying and cutting the mixture into particles to obtain the needed color master batches. The color master batches disclosed by the invention have the advantages of good dispersity and strong covering power, are easy to stir, are bleeding-free and static-free, and cannot cause environmental pollution.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a color masterbatch used for polyvinylidene fluoride OK line products. The invention also relates to a preparation method of the color masterbatch used in the polyvinylidene fluoride OK line 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, bleed, and generate static electricity. Thereby the addition amount is large, an...
