Problems solved by technology

The cables that can be made of existing refractory materials mainly include: mica tape fire-resistant cables, magnesium oxide mineral insulated cables, flexible fire-resistant cables and fire-proof mud inorganic mineral fire-resistant fire-resistant cables, etc. These cables have various shortcomings, such as: mica tape fire-resistant The cable has poor flexibility, limited thickness, slow wrapping speed and low production efficiency, resulting in high processing and labor costs; strong moisture absorption, storage for 3-6 months, and rapid decline in insulation performance after being damp; in addition, the price is high, especially is synthetic mica
Magnesium oxide mineral insulated cables are expensive, the production process is complicated and the laying is difficult

Abstract

The invention provides a ceramifying polyolefin fireproof cable material. The material is prepared by the following components in parts by weight: 40-100 parts of polyolefin; 1-30 parts of a compatilizer; 350-450 parts of ceramifying powder; 20-200 parts of a flux; 20-90 parts of a fire retardant; 2-20 parts of a lubricant; and 1-10 parts of an anti-oxidant. Polyolefin is selected from one or more of an ethane-vinyl acetate copolymer, polypropylene, polystyrene, polyethylene and a polyolefin elastomer. The ceramifying powder is selected from one or more of pottery clay, powdered steatile, mica powder, pyrophillite, ascharite, datolite, calcite, limestone, spodumene and clay. The ceramifying polyolefin fireproof cable material has the advantages of good fireproof performance, environmental protection, low cost, easy processing and good application prospect.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a cable material, and more specifically to a ceramicized polyolefin refractory cable material. Background technique [0002] With the development of society and economy, wires and cables have become an invisible and important part of people's daily life. In case of fire, it is very important to ensure the normal operation of the circuit. Therefore, in some large high-rise buildings and densely populated places, fire-resistant wires and cables have become people's subjective choice. The cables that can be made of existing refractory materials mainly include: mica tape fire-resistant cables, magnesium oxide mineral insulated cables, flexible fire-resistant cables and fire-proof mud inorganic mineral fire-resistant fire-resistant cables, etc. These cables have various shortcomings, such as: mica tape fire-resistant The cable has poor flexibility, limited thickness, slow wrapping speed ...
