Abstract

The invention discloses a modified seamless trolley wire insulation material and a preparation method thereof. The chlorinated polyvinyl chloride-acrylate copolymer modified seamless trolley wire insulation material is composed of the following components in parts by mass: 100-150 parts of chlorinated polyvinyl chloride resin, 2-4 parts of acrylate copolymer processing modifier, 15-25 parts of calcium carbonate and 1.6-2.0 parts of pigment. The preparation method of the modified seamless trolley wire insulation material comprises the following steps: weighing, high-speed mixing, low-speed cooling, curing by standing, and mold forming, thereby obtaining the finished product. The KM-355 used as the impact modifier and K-125 used as the processing modifier can effectively improve the processability of the chlorinated polyvinyl chloride, so that the impact strength and surface quality of the product are greatly enhanced. The prepared material has the advantages of outstanding high-temperature resistance, wide raw material sources, environment-friendly production process and product, and low composite cost.

Description

technical field [0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a modified seamless trolley line insulating material and a preparation method thereof. Background technique [0002] The seamless trolley line is continuous without joints, and the copper conductor and the plastic are tightly bonded, so there will be no poor contact due to vibration; the voltage drop is small, the arm of the collector frame is long, the installation is convenient, and the service life is long. Widely used in low-voltage switchgear and control equipment. Existing seamless trolley line (busway) insulation materials basically use polyvinyl chloride (PVC) and some manufacturers use acrylonitrile-butadiene-styrene polymer (ABS). The vicat of PVC and ABS softens, the temperature is about 80 ℃ and 85 ℃ respectively, and the heat resistance is poor. The aging resistance and flame retardancy of ABS are also poor. For this reason, we propose a ...
