Abstract

The invention relates to a PCTFE modified filling composite material which comprises the following components in percentage by weight: 75-95% of PCTFE polymer, 4.2-24.2% of carbon fiber and 0.3-0.8% of coupling agent. The production method comprises the following steps: (1) material mixing; (2) extruding and blending; (3) plastifying by heating; and (4) setting by cold pressing. The PCTFE modified filling composite material has the advantages of low melt viscosity, favorable flowability, favorable thermal conductivity, wide forming temperature range, low requirements for processing temperature and soaking time, and favorable product plastication, and can be formed by multiple methods.

Description

【Technical field】

[0001] The present invention relates to a homopolymer or copolymer composition containing fluorine atoms and having one or more unsaturated aliphatic group compounds, in particular to polychlorotrifluoroethylene. 【Background technique】

[0002] PCTFE (polychlorotrifluoroethylene) modified filled composite material is one of the most important high-end materials in the field of new polymer functional materials and new composite materials. Based on PCTFE material, carbon fiber or glass fiber and coupling agent are added under specific process conditions. After blending and extruding through a twin-screw extruder, it is added to the mold, heated and plasticized, and cold-pressed to shape it. PCTFE modified special functional composite new material with excellent and stable performance. The main features of this product reflect high strength, high modulus, fatigue resistance, corrosion resistance, wear resistance, low temperature resistance, high pressure resi...
