Abstract

The invention discloses a heat-resistant fire-retardant anti-freeze thermoplastic elastomer material. The heat-resistant fire-retardant anti-freeze thermoplastic elastomer material is prepared from the following raw materials: SEBS, PP, HDPE, LDPE, naphthenic oil, maleic anhydride, terpene resin, a lubricant, silicone master batch, ethylene propylene rubber, coumarone, chlorinated polyether, organic modified bentonite, organic silicon resin, other auxiliaries, hydrated alumina, an auxiliary fire retardant, an antistatic agent and turpentine. A wear-resistant heat-resistant fire-retardant anti-freeze thermoplastic elastomer presents good heat resistance performance, and has excellent low temperature resistance performance at the same time, a low temperature brittle temperature of the wear-resistant heat-resistant fire-retardant anti-freeze thermoplastic elastomer can reach -65 DEG C, and the defect that existing elastic materials are brittle at low temperatures and easy to soften at high temperatures is overcome; an obtained shaped product is in elasticity and plasticity balance, and has a good fire retardant effect, and the thermoplastic elastomer is light in weight, excellent in weather resistance performance, and is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a heat-resistant, flame-retardant, and frost-resistant thermoplastic elastomer material. Background technique [0002] Thermoplastic elastomeric materials are often used as insulating jackets for communication cables. However, when a fire occurs, the cable often loses its transmission capacity. At the same time, these materials also become the way for the flame to spread, further expanding the damage caused by the fire. Many countries are committed to the research of flame retardant cable materials. In order to prevent serious consequences caused by cable burning in case of fire. Domestic research mainly focuses on thermoplastic polyolefin elastomers. In recent years, the application of styrene thermoplastic elastomers has appeared. The research and development of thermoplastic flame-retardant polyolefin cable materials is becoming more and more obvious...
