Abstract

The invention discloses a high-flame-retardant low-gloss dynamically vulcanized thermoplastic elastomer material and a continuous preparation method thereof. The material is prepared from an ethylene-butylene elastomer, polypropylene, a cross-linking agent, lipophilic silicon dioxide, polyethylene wax, an assistant cross-linking agent, a halogen-containing flame retardant, a flame retardant aid, an anti-dripping agent, a lubricant and an antioxidant. According to the thermoplastic elastomer material, the impact resistance can be improved in the presence of the flame retardant, the flame retardant property is excellent, the V0 level can still be achieved under the condition that the thickness is 0.8 mm, the special lipophilic silicon dioxide and polyethylene wax are used for reducing the glossiness of the material, and the glossiness can be remarkably reduced. The production process of the dynamically vulcanized thermoplastic elastomer is low in energy consumption, greatly reduces the production cost, and is very suitable for large-scale process production.

Description

technical field [0001] The invention relates to a dynamic vulcanized thermoplastic elastomer with high flame retardancy and low gloss and a continuous preparation method thereof, which belongs to the field of polymer material synthesis and processing. Background technique [0002] Thanks to the high elasticity and good mechanical properties exhibited by chemical cross-linking, rubber products are currently widely used in various industries, but the sharp increase in usage has also made people find it difficult to recycle and decompose such materials, which requires high environmental protection. The modern existence of very high risk. Such as waste tires and vehicle sealing strips, etc., will cause great damage to the environment. [0003] Dynamically vulcanized thermoplastic elastomer (TPV) refers to the melt blending of rubber and thermoplastic resin under the action of high temperature shear, and the use of crosslinking agent to vulcanize the rubber in situ and disperse ...
