Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a corrosion-resistant, electrically and heat-conducting chlorinated polyvinyl chloride resin material, a preparation method and application thereof. Background technique [0002] At present, the commonly used conductive and thermally conductive plastics are usually processed by adding conductive and thermally conductive media such as nylon and PET. Rate 10 5 About 3 ~ 4W / (m.K) thermal conductivity). Chlorinated polyvinyl chloride (CPVC) is a further chlorinated modified product of polyvinyl chloride (PVC), and its chlorine content is generally 65% ​​to 72% (volume fraction). In addition to many excellent properties of PVC, CPVC has greater corrosion resistance, heat resistance, solubility, flame retardancy, and mechanical strength than PVC. Therefore, CPVC is a new material with excellent performance. It is widely used in construction, chemical industry, metallurgy, shipbuildi...
