METHOD OF PREPARING THERMOPLASTOELASTIC MATERIAL Russian patent published in 1999 - IPC

FIELD: automobile, building and other industries. SUBSTANCE: rubber and plastic material are mixed at weight ratio of 90:10-50:50 at plastic material melting temperature. Vulcanizing peroxide type agent is added in amount of 0.1-1.0 wt % per 100 wt parts of rubber. Ratio of vulcanizing agent to high molecular compound is from 1:1 to 1:10. High molecular compound is used as aqueous solution and vulcanizing agent is pretreated with said solution. Vulcanizing agent is treated with aqueous solution of inorganic acid to adjust pH at 3-4, separated and dried. EFFECT: higher physico-mechanical properties of thermoelastoplastic material. 16 ex, 1 tbl
