Abstract

The invention discloses a non-flame spread CPE rubber sheath material and a preparation method thereof. The sheath material is prepared from the following raw materials in parts by weight: 60-80 parts of chlorinated polyethylene, 15-20 parts of Teflon, 10-15 parts of dimethyl silicone rubber, 12-18 parts of chlorinated paraffin, 30-40 parts of precipitated white carbon black, 20-30 parts of gas-mixture carbon black, 5-10 parts of calcium silicate, 10-15 parts of nanometer wollastonite, 4-6 parts of octyl epoxy stearate, 10-15 parts of dioctyl maleate, 3-4 parts of dicumyl peroxide, 4-6 parts of diallyl phthalatem, 10-15 parts of ammonium polyphosphate, 5-10 parts of encapsulated red phosphorus, 3-5 parts of calcium hydrate, 1-2 parts of zine stearate, 0.5-1 part of antiager 4020, 0.5-1 part of antioxidant DLTP and 3-6 parts of a composite filling material. The sheath material of the invention is good in flame retardation effect, is not combusted when contacting with naked fire, can be quickly extinguished automatically, has non-flame spread performance and excellent fireproofness and high-temperature resistance, overcomes the defects that conventional flame-retardant cable sheath materials still can be combusted and has flame spread performance, and helps to substantially improve the usage security of cables.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a non-flammable CPE rubber sheath material and a preparation method thereof. Background technique [0002] Chlorinated polyethylene is a polymer synthetic material made from polyethylene modified by chlorination. CPE has many advantages as wire and cable sheath material: (1) excellent ozone resistance and corona resistance; (2) good aging resistance and atmospheric aging resistance; (3) good oil resistance and chemical resistance; (4) Good tear resistance and physical and mechanical properties. The CPE sheath material also has the disadvantages of insufficient high temperature resistance, flammable and delayed combustion in case of an open flame. Contents of the invention [0003] The object of the present invention is to provide a non-flammable CPE rubber sheath material and a preparation method thereof. The sheath material has the characteristics of high ...
