Methods for producing traffic signal soft cable by utilizing thermoplastic elastomer

Abstract

The invention provides methods for producing a traffic signal soft cable by utilizing a thermoplastic elastomer and relates to the technical field of production of wires and cables. The invention provides the two methods, wherein the method 1 comprises the steps of firstly granulating and then extruding; the method II comprises the step of directly extruding. Each of the two methods adopts the thermoplastic elastomer, linear low-density polyethylene, a halogen-free flame retardant, a lubricating agent, a compound antioxidant, anti-aging agent, a coupling agent and a sensitized cross-linking agent as insulating sheath raw materials; in addition, a semi-finished product is irradiated. The two methods do not pollute the environment in the production, storage and transportation processes, areharmless to a human body and cannot produce harmful gas; therefore, the traffic signal soft cable is a green and environmentally-friendly product. Through the two methods provided by the invention, the cable has good flame retardance, mechanical property, bending resistance, insulation property, heat resistance, aging resistance and the like and can meet the power standard demands.

Description

technical field [0001] The invention relates to the technical field of production of electric wires and cables. technical background [0002] In many applications, wires or cables are often required to have good flexibility. In order to meet this requirement, rubber is often used as insulation and sheath for wires and cables. Rubber is a material with high elasticity, but the processing technology of rubber is relatively complicated, the investment in equipment is large, and the area of ​​the factory building is large. Many small and medium-sized manufacturers do not have the ability to process rubber cables. [0003] In recent years, a large number of thermoplastic elastomers have emerged. People can use plastic wire and cable processing equipment to use thermoplastic elastomers as cable insulation and sheaths to produce products that are as soft as rubber cables and greatly reduce their processing costs. At present, there is no literature report on the formulation or pro...
