Cable material with high flame-retardant and fireproof performance and preparation method thereof

Abstract

The invention discloses a cable material with high flame-retardant and fireproof performance and a preparation method thereof, relates to the technical field of cable materials, and aims to solve the problems that in the cable material preparation process in the prior art, after mixed raw materials are internally mixed, the temperature of the mixed raw materials is too high and needs to be reduced for granulation, but a natural cooling method is often adopted at present, a lot of time is wasted, and the preparation speed of the cable material is influenced. The cable material comprises the following components in parts by weight: 10-20 parts of polyvinyl chloride, 15-30 parts of silicone rubber, 2-4 parts of calcium carbonate, 1-2 parts of a stabilizer, 1-2 parts of an antioxidant, 2-4 parts of di-iso-decylphthalate, 2-4 parts of trioctyl trimellitate, 3-6 parts of diphenyl anthraquinone phosphine oxide, 1-2 parts of plant ash and 1-2 parts of an anti-aging agent. Wherein the cable material is prepared through a cable preparation device, and the cable preparation device comprises a cooling box body and a placement bottom plate.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cable material with high flame-retardant and fireproof performance and a preparation method thereof. Background technique [0002] With the beginning of the industrial revolution, science and technology are constantly innovating, and electricity gradually appears. In order to better transmit electricity, it is necessary to lay long-distance cables for power transmission. The surface of the cables needs to be wrapped with thick Sheath, there is a multi-layer structure inside the sheath, which can protect the internal wires from flame retardant and fire protection. The raw material of the sheath is made of granular cable material, and the internal components of the cable material can be added according to different conditions of use. In recent years, with the continuous improvement of the requirements for cable materials, cable material production enterprises have develop...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of cable material with high flame-retardant and fire-proof properties and its preparation method, to solve the problem that during the preparation process of the cable material proposed in the above-mentioned background technology, after the mixing process of the mixed raw material, the temperature of the mixed raw material is too high. It is necessary to lower the temperature to granulate, but at present, natural cooling is often used to reduce the temperature, which wastes a lot of time and affects the preparation speed of cable materials.
