Abstract

The invention discloses an ETFE fluorine masterbatch and a production flow thereof. The ETFE fluorine masterbatch prepared by the formula and the production flow has the advantages of relatively good corrosion resistance and electric insulation property, relatively long service life, and low price. The ETFE fluorine masterbatch disclosed by the invention is prepared from the following raw materials in percentage by weight: 65%-85% of ETFE, 8%-25% of a high-temperature pigment, 3%-6% of a dispersing agent and 0.1%-1.5% of a processing agent. The invention further discloses a processing technology for preparing the ETFE fluorine masterbatch. The technology comprises the following steps: (1) burdening; (2) extruding and molding; (3) cooling; (4) dicing; (5) dewatering; (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 ETFE 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] ETFE (ethylene-tetrafluoroethylene copolymer) fluorine masterbatch is widely used in fluoroplastic color masterbatch. ETFE is a 1:1 alternating copolymer of ethylene and tetrafluoroethylene. ETFE has a melting point of 518F and a density of 1.70g / CC. ETFE is a tough material with high impact resistance and good mechanical properties from low temperature to 356F. Chemical resistance, electrical properties and weather resistance are similar to ECTFE and similar...
