Efficient flame retardant cable sheath material

Abstract

The invention discloses an efficient flame retardant cable sheath material which comprises the following raw materials in parts by weight: 80-100 parts of methyl vinyl silicone rubber, 16-23 parts of fumed silica, 11-17 parts of precipitated white carbon black, 1.3-2.2 parts of octamethylcyclotetrasiloxane, 30-40 parts of diatomite, 2-3 parts of titanium dioxide, 1.5-2.5 parts of titanium dioxide, 0.13-0.25 part of ferric oxide, 0.3-1 part of peroxidized bi(2, 4-dicholorbenzoyl), 0.5-0.9 part of 2, 5-dimethyl-2, 5-bi(tertiary butyl peroxy) hexane, 0.0015-0.002 part of platinum flame retardant, 15-20 parts of aluminum hydroxide, 20-30 parts of magnesium hydrate, 1-1.5 parts of dioctahedron alkaline aluminum silicate and 0.4-0.7 part of trioctahedron alkaline aluminum silicate. The efficient flame retardant cable sheath material disclosed by the invention is free from pollution, excellent in flame retardant effect and good in high-temperature self-extinguishing effect, and has certain strength and supporting capacity after combustion.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a high-efficiency flame-retardant cable sheath material. Background technique [0002] With the rapid development of the economy, the demand for cable sheath materials is increasing and the requirements are getting higher and higher. With the increasingly stringent environmental protection and recycling regulations and the continuous emergence of new sheath materials, traditional cable materials are facing challenges. Huge challenge. Traditional sheath materials are generally completely burned when exposed to open flames. In order to prevent flames and self-extinguishing, halogen-containing flame retardants are generally added to the sheath materials. Although the effect is very good, a large amount of toxic and corrosive gases are released when burning , accompanied by a large amount of smoke.

[0002] With the rapid development of the economy, the demand for cable sheath materials is increasing and the requirements are getting higher and higher. With the increasingly stringent environmental protection and recycling regulations and the continuous emergence of new sheath materials, traditional cable materials are facing challenges. Huge challenge. Traditional sheath materials are generally completely burned when exposed to open flames. In order to prevent flames and self-extinguishing, halogen-containing flame retardants are generally added to the sheath materials. Although the effect is very good, a large amount of toxic and corrosive gases are released when burning , accompanied by a large amount of smoke

[0003] The current technology mainly uses halogen-free low-smoke flame-retardant rubber, mainly silicone rubber, ethylene-propylene rubber and ethylene-vinyl acetate rubber, etc. These rubbers are flame retardant and self-extinguishing in fire, and have certain However, after continuous high-temperature combustion, the burning residue has no mechanical strength and turns into ashes, which will cause more dangerous secondary hazards. The protection of personal and property safety in fires is a major concern of people. How to prepare a non-polluting, anti-corrosion Excellent combustion effect, good high temperature self-extinguishing effect, cable sheath material with certain strength and support ability after burning has become a technical problem that needs to be solved at present
