Polyvinyl chloride insulated cable material suitable for high-speed production of automobiles and preparation method of polyvinyl chloride insulated cable material

Abstract

The invention relates to a polyvinyl chloride insulated cable material suitable for high-speed production of automobiles and a preparation method of the polyvinyl chloride insulated cable material. Active components of the polyvinyl chloride insulated cable material consist of the following raw materials in parts by weight: 45-50 parts of PVC resin powder, 1-3 parts of oxidized polyethlene wax, 25-35 parts of a plastifier TOTM, 1-3 parts of a lubricant G16, 2-5 parts of a calcium zinc stabilizer, 15-20 parts of nanometer level calcium carbonate, 0.5-1 part of an antioxidant, 0.5-1 part of a surface treating agent, 1-3 parts of zinc stearate and 0.5-1 part of a coupling agent. The PVC soft resin powder and the oxidized polyethlene wax are pre-stirred, so that the polymerizing degree of mixed materials is higher, besides, when the temperature of substrates is lower than that of squeezed materials, the melting state is reached quickly, and high-speed squeezing is facilitated; and the antioxidant is added, so that after the materials are squeezed for shaping, under the adverse use condition, the antioxygenic property of products can be greatly improved, and the safety property of the products in the use course can be higher.

Description

Technical field: [0001] The invention relates to a polyvinyl chloride insulated cable material suitable for high-speed production of automobiles and a preparation method thereof Background technique: [0002] With the rapid development of social economy, wires and cables have been widely used in all walks of life. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. Smoke and toxic and corrosive gases are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, causing serious losses of life and property. In addition, during the production process of existing cable materials, the matrix material has poor fluidity and is usually mixed unevenly, resulting in poor performance of the processed product; moreover, after mixing, the matrix material has poor adhesion and is not easy to Kneading; Finally, although the existing ...

[0002] With the rapid development of social economy, wires and cables have been widely used in all walks of life. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. The smoke and toxic and corrosive gases are dangerous factors in the fire, which hinder people's safe evacuation and fire fighting work, and cause serious loss of life and property.

In addition, during the production process of existing cable materials, the matrix material has poor fluidity and is usually mixed unevenly, resulting in poor performance of the processed product; moreover, after mixing, the matrix material has poor adhesion and is not easy to Kneading; Finally, although the existing cable materials are also added with a certain amount of lubricant, the appearance of the product is still rough, uneven and dull when extruded
