Problems solved by technology

Its disadvantages are that the processing temperature is high (280°C), the flame retardancy is low, the crystallinity is high, it is not easy to add flame retardants, the elongation is very low, the notched impact strength is low, and the product is hard and brittle, so it cannot be used in the required Suitable for flexible, flame-retardant wires and cables, and environments that require low temperature resistance
Nylon, ethanol terephthalate and polyester ether copolymer elastomers, due to their molecular and high crystal structure, not only cannot be effectively cross-linked under electron irradiation, but also have the phenomenon of decomposition and embrittlement

Abstract

The invention discloses a weatherable irradiation crosslinking cable material. Raw materials of the cable material comprise the following components, by weight, 100 parts of a thermoplastic elastomer, 0-35 parts of an engineering plastic, 2-80 parts of a polyolefin, 0.2-8 parts of a crosslinking agent, and 2-150 parts of a fire retardant. According to the invention, problems existing in manufacturing of cable materials from polyester copolymers are solved through reasonably designing the components and the ratio of the components, and utilizing the interaction of the components; and the prepared cable sheath material has the advantages of good processing fluidity, good mechanical properties, oil resistance, high temperature resistance, excellent hot extensibility and superior low temperature resistance after irradiation crosslinking, and substantial reduction of the material cost through the addition of the polyolefin interface phase solvent.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a weather-resistant radiation cross-linked cable material. Background technique [0002] The characteristics of engineering plastics are high strength, high crystallinity and high rigidity polymer materials. Polyester engineering plastics mainly refer to saturated polyester thermoplastic engineering plastics, which have the advantages of extremely high strength, friction resistance and weather resistance. It is one of the five major engineering plastics, mainly including polyethylene terephthalate (PET) and Polybutylene terephthalate (PBT). Polybutylene terephthalate has a faster crystallization speed, can be injection molded at a higher speed, and has excellent weather resistance, electrical properties, chemical resistance, and abrasion resistance. Therefore, it is widely used in electronic, electrical and other industrial fields. Its shortcomings are high processing temperature (2...
