Problems solved by technology

[0003] FEP (fluorinated ethylene propylene copolymer) fluorine masterbatches in fluoroplastic masterbatches are widely used, but the formulation technology and processing technology of fluoroplastic masterbatches have been monopolized by foreign companies for a long time, and most of the materials used in China are imported materials. Therefore, its price is relatively high, but the fluoroplastic color masterbatch made in China, especially the FEP fluorine masterbatch, has poor corrosion resistance, poor electrical insulation performance and short service life.

specific Embodiment approach

[0028] The FEP fluorine masterbatch of the present invention can be made from the raw materials of the following weight ratio:

[0029] 65% to 85% FEP;

[0030] 8%~25% high temperature pigment;

[0031] 3% to 6% dispersant;

[0032] 0.1% to 2% processing aids.

[0033] The present invention also discloses a processing technique for preparing the above-mentioned FEP fluorine masterbatch, comprising the following steps:

[0034] (1) Ingredients: 65% to 85% of FEP, 8% to 25% of high-temperature pigments, 3% to 6% of dispersants and 0.1% to 2% of processing aids are weighed according to the weight ratio;

[0035] (2) extrusion molding; mixing the ingredients weighed in step (1) into a twin-screw extruder for mixing and plasticization, and carrying out vacuum moisture treatment, and finally extrusion molding;

[0036] (3) cooling; the product extruded in step (2) is rapidly cooled, so that the product after mixing is rapidly crystallized, the surface temperature is reduced, and...

Abstract

The invention discloses an FEP fluorine color master batch and a processing technique of the FEP fluorine color master batch. The FEP fluorine color master batch processed through the formula and the processing technique has better corrosion resistance, better electrical insulation property, longer service life and a lower price. The FEP fluorine color master batch comprises, by weight, 65%-85% FEP, 8%-25% high-temperature pigment, 3%-6% dispersing agents and 0.1-2% processing agents. The processing technique of the FEP fluorine color master batch comprises the steps of material allocation, extrusion molding, cooling, sized dicing, dewatering, sorting, drying and packaging for storage.

Description

technical field [0001] The invention relates to the field of fluoroplastic color masterbatch, in particular to FEP fluorine color masterbatch and its processing technology. Background technique [0002] Fluoroplastic color masterbatches are mainly used in internal wires and lead wires of aviation, ships, electronic equipment, wires and cables in public places such as computer networks, subways, vehicles, high-rise buildings, internal wires of traditional communication equipment and other fluoroplastic products; [0003] FEP (fluorinated ethylene propylene copolymer) fluorine masterbatches in fluoroplastic masterbatches are widely used, but the formulation technology and processing technology of fluoroplastic masterbatches have been monopolized by foreign companies for a long time, and most of the domestically used materials are imported. Therefore, its price is relatively high, but the domestically processed fluoroplastic masterbatch, especially FEP fluorine masterbatch, has...
