Problems solved by technology

[0008] Aiming at the disadvantages of poor cold resistance and low-temperature impact performance of polyvinyl chloride materials in the prior art, the purpose of the present invention is to provide an environment-friendly cold-resistant polyvinyl chloride cable material and its preparation method. Dioctyl formate and dioctyl adipate (and other aliphatic dibasic acid esters) are compounded, and the prepared cable material can be used normally at a low temperature of -40°C to -65°C. It has good impact resistance and does not contain phthalate compounds, so it is environmentally friendly, thus solving the problem that the existing PVC cable material is not environmentally friendly and has poor impact resistance under low temperature conditions

Abstract

The invention provides an environment-friendly cold-resistant polyvinyl chloride cable material and a preparation method thereof. The environment-friendly cold-resistant polyvinyl chloride cable material is prepared from the following raw materials in percentage by mass: 40-60% of polyvinyl chloride, 5-25% of dioctyl terephthalate, 5-25% of dioctyl adipate, 1-10% of chlorinated polyethylene, 5-25% of light activated calcium carbonate, 1-3% of lubricant, 2-8% of Ca-Zn composite stabilizer, 0.1-1% of antioxidant and 0.1-4% of pigment. The environment-friendly cold-resistant polyvinyl chloride cable material is mainly compounded from dioctyl terephthalate and dioctyl adipate. The cable material can be normally used in a low-temperature environment of -40 to -65 DEG C, has favorable shock resistance under low-temperature conditions, does not contain ortho-benzoic ether compounds, and is environment-friendly, thereby solving the problem that the existing polyvinyl chloride cable material is not environment-friendly and has poor shock resistance under low-temperature conditions.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to an environment-friendly cold-resistant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride plastic has good physical and mechanical properties, and is widely used in building materials, packaging materials, electronic materials, cables in the automotive industry, and daily necessities. However, the cold resistance and low-temperature impact performance of polyvinyl chloride plastic are poor, which limits its application at low temperature (-20°C to -40°C). [0003] For a long time, with the emergence of new plasticizers, the application range of polyvinyl chloride plastics has been improved. Currently commonly used plasticizers are mainly phthalates such as dioctyl phthalate (DOP). As phthalate is widely used in food, medicine and other industries, people pay more and more attention to its toxi...
