Abstract

The invention discloses a scraping resistance halogen-free flame retardant thermoplastic elastomer composition, which comprises the following ingredients in percentage by weight: 15 to 50 percent of poly-phenylate resin, 20 to 40 percent of styrene thermoplastic elastomers, 10 to 30 percent of solid halogen-free flame retardants, 0.5 to 5 percent of flame retardant synergists, 5 to 20 percent of plasticizers and 5 to 20 percent of scraping resistance agents. The halogen-free flame retardant thermoplastic elastomer composition provided by the invention has the advantages that polysiloxane is added into the halogen-free flame retardant thermoplastic elastomer composition in a polymer form, the excellent scraping resistance is realized, the original mechanical property, the flame retardant performance, the appearance and the soft hand feeling are not damaged, on the basis, the viscosity of the composition in the extruding processing process can also be reduced, the energy consumption is reduced, and better low-carbon and environment-protection effects can be realized.

Description

technical field [0001] The invention belongs to the field of processing and modification of polymer materials, and in particular relates to a scratch-resistant halogen-free flame-retardant thermoplastic elastomer composition and a preparation method thereof. Background technique [0002] As one of the important inventions of human industrial civilization, wires and cables have been widely used in the transmission of various types of electric energy and signals. Compared with other materials, polymer has the advantages of light specific gravity, easy molding, good comprehensive mechanical properties and excellent electrical insulation properties, so it has become the preferred base material for various wire and cable coverings. Over the years, soft PVC materials (including various additives such as stabilizers, plasticizers, and fillers) have been the preferred choice for wires due to their necessary mechanical strength, excellent flexibility, relatively low price, and mature...
