Problems solved by technology

When such materials are applied to low-voltage wires such as electrical wires, electronic wires, signal wires, earphone wires, audio wires, and USB wires, there are four deficiencies in their material properties: First, the resistance of low-smoke, halogen-free flame-retardant materials The combustion and filling system is a metal hydroxide material, and the filling content is as high as 65%, which leads to a decrease in the performance of the product wire. In the subsequent use and processing, it is easy to appear scratches and other appearance phenomena; The flame retardant efficiency is not high. In the production of some wires and cables with complex structures and thick walls, the

Abstract

The invention provides a macromolecular flame-retardant elastomer environment-friendly material and a preparation method thereof. The macromolecular flame-retardant elastomer environment-friendly material consists of thermoplastic styrene elastomer, polypropylene, polyethylene octene co-elastomer, a phosphorus nitrogen series composite flame retardant, a flame-retardant synergist, a compatilizer, white oil, an antioxidant and a coloring agent. The preparation method comprises the following steps of: mixing the raw materials in a ratio, extruding, drawing, granulating, and thus obtaining the material. The material has good physical property, and is suitable for making low-voltage wires such as electronic wires, earphone wires, audio wires, universal serial bus (USB) wires, computer flat cables and signal wires on the premise that good flame-retardant performance is ensured.

Description

Technical field [0001] The invention belongs to the field of polymer materials, and particularly relates to a polymer flame-retardant elastomer environmental protection material and a preparation method thereof. Background technique [0002] At present, one of the most widely used materials in the wire and cable industry is polyvinyl chloride (PVC), which is a halogen-based material and a polymer material with a chlorine content of up to 50%. It is also added in the wire and cable manufacturing process A large number of other harmful modified substances make PVC materials not environmentally friendly. When PVC materials are burned, halogenated hydrogen and other toxic gases (such as dioxins) are produced. In the event of a fire, it is extremely harmful to the human body and suffocates people to death. The environmental protection performance of PVC materials is insufficient and the hazard of fire. European and American countries (such as the United States, Germany, Britain, Swi...
