Abstract

A rubber alloying colloid and its process are disclosed. The process includes PVC swelling, internal mixer plasticizing and mill mixer plasticizing. The PVC consists of PVCH2000, DOP, dihydrochloride, trihydrochloride, calcium stearate and barium stearate; the temperature of sweller is set 70-80 Deg C. for 5mins, the mill components consist of NBR, swelling PVC, 4010 and NBC. The process is carried out by putting into raw materials, raising temperature to 145 Deg C., pouring into cooling water, unloading materials at 150 Deg C. after 15mins, heating mill mixer to 130 Deg C. with roller spacing 1mm, plasticizing colloid from internal mixer, putting it into mill mixer, cooling plasticized colloid and piling. It has excellent ozone-proof, high and low temperature-resistant performances and no impurities.

Description

technical field [0001] The invention relates to a rubber-plastic alloy and a production process, in particular to a rubber-plastic alloy and a production process for extruding rubber from the outer tube of oil pipes and fuel hoses. Background technique [0002] At present, the rubber-plastic alloy glue produced in our country is used for molding products, and the plasticization is generally carried out by kneader or screw extrusion, and the mixed rubber cannot be used to extrude the rubber compound, because the rubber compound is extruded. Rough appearance after exiting. The Chinese patent application (patent application number: 98115829, announcement date: January 26, 2000) with the title of "multi-component thermoplastic elastomer combination with filling, solubilization and vulcanization improvement" discloses a compound with filling, solubilization and vulcanization. The multi-component thermoplastic elastomer combination improved by vulcanization is a thermoplastic rub...
