Embodiment 1

[0018] An anti-aging flame-retardant cable insulation material is characterized in that it comprises the following components by weight:

[0019] 60 parts of polyvinyl chloride resin, 20 parts of modified talcum powder, 1 part of didodecanyl thiodipropionate anti-aging agent, 2 parts of azelaic acid ester plasticizer, 1 part of benzophenone stabilizer , 0.5 parts of polysiloxane antibacterial agent, 4 parts of phthalic acid, 3 parts of melamine polyphosphate, 0.2 parts of barium sulfate.

[0020] The preparation method of described modified talcum powder is: add talcum powder to the water of 20 times of talcum powder weight, stir and mix evenly, then add the carboxymethyl chitosan that viscosity is 100cps, the mixture of carboxymethyl chitosan and talcum powder The weight ratio is 1:2, the temperature is raised to 50°C, and the stirring is continued for 1 hour. After standing for 4 hours, the modified talc powder is obtained by filtering and drying in sequence.

Abstract

The invention relates to the technical field of a cable material, and discloses an anti-aging flame-retardant cable insulation material. The cable insulation material comprises the following components in parts by weight: 60 to 80 parts of polyvinyl chloride resin, 20 to 30 parts of modified powdered steatile, 1 to 3 parts of an anti-aging agent of dilauryl thiodipropionate, 2 to 3 parts of a sebacate plasticizer, 1 to 3 parts of a benzophenone stabilizer, 0.5 to 1 part of a polysiloxane antibacterial agent, 4 to 6 parts of phthalic acid, 3 to 5 parts of melamine pyrophosphate, and 0.2 to 0.6parts of barium sulfate. The cable insulation material has good flame resistance and age-proof performance.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an anti-aging and flame-retardant cable insulation material. Background technique [0002] With the development of the economy, the demand for wire and cable is increasing, especially in the fields of high-rise buildings, electronic products, electrical appliances, automobiles, computers and aerospace industry products, the requirements for cable materials are also getting higher and higher. The cable material is generally made of polyvinyl chloride, which has a series of advantages such as good mechanical properties, excellent electrical properties, chemical resistance, cold resistance, and good oil resistance. It is an ideal industrial wire and cable material. However, PVC materials have poor aging resistance and flame retardancy. Chinese Patent Publication No. CN103351556 discloses a flexible polyvinyl chloride wire and cable material, which is composed of the followi...
