Abstract

The invention discloses a reactive extrusion functionalized SIS material, and a preparation method thereof. The reactive extrusion functionalized SIS material is prepared from, by weight, 90 to 110 parts of SIS, 5 to 10 parts of dibutyl maleate, 0.2 to 0.5 part of a initiator, 0.1 to 0.3 part of an anti-oxidant, 0.2 to 0.5 part of EBS, and 50 to 100 parts of naphthenic oil. According to the preparation method, grafting of a functional monomer with large molecular chains is realized, so that SIS is provided with polarity, the bonding force with inorganic filling materials is increased, and mechanical properties are improved obviously without influencing other comprehensive performance; the reactive extrusion functionalized SIS material can be used for preparing cable insulation materials or sheath with high requirements on mechanical properties; market diversification requirements are satisfied; and application field is widened.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a reactive extrusion functionalized SIS material and a preparation method thereof. Background technique [0002] SIS is a styrene-isoprene-styrene block copolymer. It is a thermoplastic elastomer with excellent performance. It has excellent corrugation sealing and high temperature retention. Its unique microscopic phase separation structure determines its It has unique advantages when used as an adhesive. The pressure-sensitive adhesive and hot-melt adhesive prepared are widely used in medical treatment, electrical insulation, packaging, protective masking, marking, bonding and fixing, etc., especially for the production of hot-melt pressure Sensitive adhesive (HMPSA) has the characteristics of no solvent, no pollution, low energy consumption, simple equipment, and wide bonding range. It is very popular among users and has developed rapidly in recent years. [0003] Howev...
