Abstract

The invention discloses a polyvinyl chloride bushing for electrician. The raw materials include 50-60 parts of polyvinyl chloride, 5-10 parts of zeolite powder, 10-20 parts of talc powder and 10-20 parts of wollastonite powder in parts by weight. , 10-18 parts of fly ash, 8-16 parts of bentonite, 20-30 parts of expanded perlite, 4-8 parts of plasticizer, 1-2 parts of silane coupling agent, 1-2 parts of titanate coupling agent , 5-9 parts of cross-linking agent. The polyvinyl chloride bushing for electrician provided by the invention has good toughness, high pressure resistance, high flexural strength and excellent thermal stability.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride sleeves, in particular to a polyvinyl chloride sleeve for electricians. Background technique [0002] Electrical PVC casings have been produced in my country for many years, with a complete range of models and generally good quality. Its sales have been soaring along with the real estate industry. Now the ordinary PVC casings on the market have more and more diversified classifications in terms of performance to adapt to various circuit uses. However, when wiring the interior walls of our homes and industrial plants, the requirements for compressive strength and impact resistance are relatively high, and the thermal stability cannot meet the requirements, which needs to be improved urgently. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a polyvinyl chloride bushing for electrical purposes, which has goo...
