Problems solved by technology

[0007] Although the technical solutions disclosed in the above two patent documents solve the problems of poor UV resistance and flammability of TPE materials, the UV absorbers used in them are all benzophenones and benzotriazole organic compounds.
Therefore, it is unstable, has a short lifespan, and has relatively large side effects, and has certain toxicity and irritation.

Abstract

The invention relates to an ultraviolet-resistant halogen-free flame-retardant thermoplastic elastomer TPE material and a preparation method thereof. The ultraviolet-resistant halogen-free flame-retardant thermoplastic elastomer TPE material contains the following components in parts by weight: 15-35 parts of elastomer resin SEBS, 10-25 parts of naphthenic oil, 10-25 parts of polypropylene resin, 1-10 parts of ultraviolet absorbent, 10-30 parts of halogen-free synergist, 10-20 parts of flame retardant synergist, 1-5 parts of compatilizer, 0.2-1 part of antioxidant and 0.3-2 parts of lubricant. The ultraviolet-resistant halogen-free flame-retardant thermoplastic elastomer TPE material prepared by the invention has good ultraviolet resistance, generates low smoke in burning and can reach V0 flame-retardant level. The ultraviolet-resistant halogen-free flame-retardant thermoplastic elastomer TPE material does not contain harmful heavy metals, halogen and chemical substances endangering human health and natural environment, can be repeatedly recycled and is suitable for the fields of outdoor sports and wires and cables and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an ultraviolet-resistant, halogen-free, flame-retardant thermoplastic elastomer TPE material and a preparation method thereof. The material is widely used in the fields of outdoor sports and electric wires and cables. Background technique [0002] Thermoplastic elastomer (TPE) is a polymer material that has the high elasticity of traditional vulcanized rubber at room temperature and can be plasticized at high temperature. Because of its many advantages in use and processing performance, TPE materials have been widely used in many fields. [0003] Various outdoor sports products made of TPE materials have the high elasticity of rubber, environmental protection and non-toxic properties, and their prices are much lower than traditional rubber, so TPE materials have the possibility of replacing traditional rubber. However, limited by the molecular structure, the mechanical propertie...
