Abstract

The invention discloses a fire-resistant and extrusion-resistant cable material. The fire-resistant and extrusion-resistant cable material is prepared from polyvinyl chloride resin, antioxidant, plasticizer, flame retardant, modifier, light stabilizer and calcium carbonate. The fire-resistant and extrusion-resistant cable material has excellent fire-resistant performance and extrusion-resistant performance, meanwhile, a method for preparing the cable protective sleeve is simple, and the raw materials are easy to obtain.

Description

technical field [0001] The invention relates to a cable material, in particular to a fire-resistant and extrusion-resistant cable material. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. [0003] Although ethylene polymers have excellent properties, their calorific value of combustion increases with the increase of ethylene content. With the increase of ethylene content, its flame retardant performance has been improved to a certain extent, but it still cannot meet the requirements of some special fields. It produces black smoke with toxic gas during the combustion process, which limits its application in household appliances, construction and building materials. and cable applications.
