Abstract

The invention discloses a high-flame retardant high-temperature retardant cable insulation material. The cable insulation material comprises, by weight, 100 parts of an ethylene propylene diene monomer, 10 to 20 parts of vinyl polysiloxane, 5 to 15 parts of vinyl phenyl polysiloxane, 20 to 40 parts of bis(2, 3-dichloropropyl)hexamethylenetetramine phosphate (single-component intumescent flame retardant), 10 to 20 parts of cyclodextrin, 5 to 10 parts of nano-mica, 5 to 10 parts of nano-kaolin, 0.5 to 1 part of glyceryl monostearate and 1 to 3 parts of dicumyl peroxide. The bis(2, 3-dichloropropyl)hexamethylenetetramine phosphate and cyclodextrin can form an inclusion compound in the cable insulation material. Through use of excellent transportation and dispersion ability of the cyclodextrin, the flame retardant can be uniformly dispersed at the molecular level in the resin matrix so that the flame retardant effects are greatly improved.

Description

technical field [0001] The invention relates to a cable insulating material and a preparation method thereof, in particular to a high flame-retardant and high temperature-resistant cable insulating material and a preparation method thereof. Background technique [0002] Existing cable insulation materials have unsatisfactory flame retardant and high temperature resistance effects. In order to achieve high temperature resistance, polymer resins are often added to their components; in order to achieve flame retardant effects, flame retardants are often added to their components; However, the flame retardant effect is largely affected by the dispersion uniformity of the flame retardant in the entire material; the polymer resin and the flame retardant have huge differences in molecular weight and physical and chemical properties, and the compatibility is poor. The flame retardant is often difficult to disperse evenly in the polymer resin matrix, which leads to unsatisfactory fla...
