Problems solved by technology

[0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has light weight, high strength, insulation, flame retardancy, corrosion resistance, It has the advantages of excellent comprehensive performance, low price and wide source of raw materials; but it also has the following disadvantages: 1. Poor toughness, easy to be brittle when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. Large

Description

Technical field [0001] The invention relates to the technical field of PVC modified materials, in particular to a transparent light-shielding PVC modified material for wires and cables and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general thermoplastics. It has the advantages of light weight, high strength, insulation, flame retardant, corrosion resistance, excellent comprehensive performance, low price and wide raw material sources; but also There are the following shortcomings: 1. Poor toughness, easily brittle and cracked when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. The lower limit of use for general PVC products is -15°C, soft The lower limit of the use of PVC is -30℃; 2. The thermal stability is poor. It starts to decompose HCl at 100℃, and decomposes more rapidly when it is hi...
