Abstract
The application provides an insulating polyvinyl chloride alloy elastomer polymer and a preparation method thereof, belonging to the field of high molecular polymers. The insulating polyvinyl chloride alloy elastomer polymer comprises the following components in parts by weight: 100-150 parts of polyvinyl chloride resin, 35-70 parts of plasticizer, 6-15 parts of stabilizer, 5-10 parts of flame retardant, 5-10 parts of insulating auxiliary agent, 0.5-1.0 part of lubricant, 0.2-0.5 part of antioxidant, 10-30 parts of toughening agent and 2-5 parts of processing auxiliary agent. The application adopts BYDL1480 and BYXG2500 as raw materials of polyvinyl chloride resin, and the mixture of the raw materials with specific plasticizer, flexibilizer, insulating auxiliary agent and processing auxiliary agent not only can improve the insulating effect of polyvinyl chloride alloy elastomer polymer, but also has no influence on the mechanical properties of the product, and can be used as a protective layer of wires and cables under severe conditions.
Description
Technical Field
The application belongs to the field of high molecular polymers, and particularly relates to an insulating polyvinyl chloride alloy elastomer polymer and a preparation method thereof.
Background
Polyvinyl chloride is an industrial general resin with good performance, is a plastic polymer with wider application, and is usually manufactured into various products due to lower price and lower production cost. At present, two types of hard and soft polyvinyl chloride products mainly exist in the market. The hard polyvinyl chloride plastic is widely used in industries such as construction and decoration due to the advantages of high strength, high hardness, corrosion resistance and the like, but with the improvement of demands, people can widen the application range of the hard polyvinyl chloride plastic in order to improve the defects of high brittleness, difficult processing and the like of the hard polyvinyl chloride, and the modified polyvinyl chloride elastomer is widely used in various industrial fields such as military industry, automobiles, navigation, aviation, electronics and the like due to the excellent performance of the modified polyvinyl chloride elastomer.
In addition, with the development of electric vehicles, in order to adapt to the development situation of electric vehicles, many cities are provided with charging piles, and the charging piles are generally installed outdoors, so that the polymer materials used for the cables used by the charging piles need to have excellent weather resistance and insulation.
But the existing cable sheath material has poor strength and crack resistance, is extremely easy to crack under external pressure in the use process, influences the normal use of the cable, and causes increased potential safety hazard.
