Antiflaming shock resistant modified PVC cable sheath material

Abstract

The invention relates to a cable material, and particularly relates to an antiflaming shock resistant modified PVC cable sheath material. The material is prepared from the following raw materials in parts by weight: 24-28 parts of PVC resin, 21-23 parts of poly 1-butene, 12-14 parts of low density polyethylene, 14-15 parts of dioctyl adipate, 13-14 parts of epoxidized soybean oil, 23-25 parts of calcined kaolin, 6-9 parts of aluminum hydroxide, 4-5 parts of zinc borate, 2-3 parts of barium stearate, 2-3 parts of silane coupling agent KH550, 3-4 parts of sodium tripolyphosphate, 1-2 parts of tantalum boride, 1-2 parts of accelerator DM, 2-3 parts of zinc oxide, 4-5 parts of dimethyl phosphite, 1.3-1.5 parts of accelerator D, and 14-16 parts of additive. The insulating material combines advantages of the raw materials like PVC resin, poly 1-butene and the like, is flexible and impact resistant, has good chemical stability, is antiflaming, resists weather ageing cracking, is safe and reliable in use, can be widely used for preparing various cable sheath insulating materials, and has broad market demand prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a flame-retardant and impact-resistant modified PVC cable sheath material and a preparation method thereof. Background technique [0002] With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, service temperature, flame retardant performance and other indicators There are strict requirements, and continuous improvement of the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials often have poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life. And other problems, bring a lot of inconvenience to the actual use, and even threaten people's life and property safety, the...

[0002] With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, service temperature, flame retardant performance and other indicators There are strict requirements, and continuous improvement of the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials often have poor flame retardancy, poor chemical stability, high temperature deformation, poor mechanical properties, and short service life. And other problems, bring a lot of inconvenience to the actual use, and even threaten the safety of people's lives and property. Therefore, it is urgent to change the original sheath material formula and improve the material performance to meet the diverse needs of the cable market.
