Problems solved by technology

[0003] In order to improve the flame retardancy of the existing cable materials, aluminum hydroxide is added to the raw materials. Since the surface of aluminum hydroxide has a large number of hydrophilic groups, it is extremely difficult to integrate well with non-polar materials, and there is an obvious Due to the difference in the interface, it cannot be uniformly dispersed in the polymer matrix, and it is easy to agglomerate, which limits its application range and affects the mechanical properties of cable materials.

Abstract

The invention belongs to the technical field of cable material production, and more specifically relates to a halogen-free flame-retardant cable material. The halogen-free flame-retardant cable material is prepared from 100 to 140 parts of polyvinyl chloride resin; 4 to 12 parts of epoxidized soybean oil; 0.3 to 0.8 part of polyethylene wax; 15-30 parts of diisononyl phthalate, 20-28 parts of dioctyl terephthalate, 4-10 parts of a calcium-zinc composite stabilizer, 10-18 parts of magnesium hydroxide, 15-27 parts of aluminum hydroxide, 10-18 parts of magnesium-aluminum hydrotalcite, 3-9 parts of plant ash, 1-4 parts of paraffin oil, 2-6 parts of zinc oxide and 0.5-1.8 parts of hydroxyl silicone oil. The halogen-free flame-retardant cable material is capable of avoiding the defects in the prior art, and magnesium hydroxide and magnesium-aluminum hydrotalcite are added into the cable material, so that the polymerization degree of the cable material is improved, the mechanical strength ofthe cable material is improved, and meanwhile, the flame resistance of the cable material is improved.

Description

technical field [0001] The invention relates to the technical field of cable material production, in particular to a halogen-free flame-retardant cable material. Background technique [0002] Wire and cable are commonly known as cable materials. The base material of cable materials is mainly PVC plastic. PVC plastic is one of the five general-purpose synthetic plastics and is the second largest plastic variety in the world after polyethylene. Due to its good physical and mechanical properties, polyvinyl chloride resin can be used in the production of building materials, packaging materials, electronic materials, daily consumer goods, etc., and is widely used in various fields such as industry, agriculture, construction, transportation, power telecommunications, and packaging. Wire and cable are indispensable and important facilities for industrial and agricultural production and modern life. [0003] In order to improve the flame retardancy of the existing cable materials, ...
