Problems solved by technology

[0004] However, the formulation technology and processing technology of fluoroplastic color masterbatches, especially PFA fluoroplastic color masterbatches, have been monopolized by foreign companies for a long time. Masterbatches, especially PFA fluorine masterbatches, have poor corrosion resistance, poor electrical insulation performance, and short service life.

Abstract

The invention discloses a PFA fluorine color masterbatch and a production process thereof. The PFA fluorine color masterbatch produced by virtue of a formula and the production process has excellent corrosion resistance and electrical insulation performance and is relatively long in service life and low in cost. The PFA fluorine color masterbatch is produced from the following raw materials in percentage by weight: 65%-85% of PFA, 8%-25% of a high-temperature pigment, 3%-6% of a dispersing agent and 0.1%-2% of a machining aid. The invention also discloses the production process of the PFA fluorine color masterbatch, comprising the following steps: (1) burdening; (2) molding by extrusion; (3) cooling; (4) granulating; (5) dehydrating; (6) sorting; (7) drying; and (8) packaging and warehousing.

Description

technical field [0001] The invention relates to the field of fluoroplastic color masterbatch, in particular to PFA fluorine color masterbatch and its production process. 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] The application of PFA (soluble polytetrafluoroethylene) fluorine masterbatch in fluoroplastic masterbatch is very extensive. PFA is mainly a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. Enhanced melt adhesion, decreased melt viscosity, and no change in performance compared with PTFE; excellent chemical resistance, corrosion resistance to all chemicals, lowest coefficient of friction among plastics, and good E...
