Abstract
The invention belongs to the technical field of production and processing of polymer modified materials, and in particular relates to a low-temperature blow-molding TPE (thermoplastic elastomer) material for a washing machine drain pipe for extrusion molding. The low-temperature blow-molding TPE material is composed of the following components in parts by weight: 100-200 parts of SEBS (styrene-ethylene/butadiene-styrene block copolymer), 50-100 parts of white oil, 100-140 parts of polyethylene and 0.2-0.4 part of stabilizer, wherein the stabilizer is a mixture of main antioxidant 1010 and auxiliary antioxidant 168 in a ratio of 1: 1, and the white oil is one or two of paraffin oil or naphthenic oil. The low-temperature blow-molding TPE material has the advantages of being subjected to low-temperature extrusion blow-molding, good in rebound resilience, high in strength, environment-friendly and reusable.
