Problems solved by technology

However, the price of POE is more expensive, which makes the cost of TPO products of POE / PP system higher. Moreover, because the dynamic vulcanization method uses peroxide as a crosslinking agent, odor will be generated during material processing, which has a certain impact on the environment.

Abstract

A process for preparing new type of TPO includes obtaining seed masterbatch made of polypropylene, ethylene-octene copolymerized elastomer styrene-butadiene-styrene ternary block copolymer, valcanizing agent, cross-linking agent by dynamic valcanizing and cross-linking in scrow extrudor; adding nanotalcum powder and assistants; extruding and pelletizing.

Description

technical field [0001] The present invention relates to a polyolefin thermoplastic elastomer. Background technique [0002] Polyolefin thermoplastic elastomer (TPO) is a high-performance thermoplastic elastomer material with excellent elastomer properties, good processing performance and excellent weather resistance. It is widely used as a substitute for rubber in automobiles, cables, textiles, fields such as construction and home appliances. TPO is mainly composed of rubber and polyolefin. Rubber mainly includes EPDM, nitrile rubber (NBR) and butyl rubber. Polyolefins mainly include polypropylene (PP) and polyethylene (PE). At present, TPO of EPDM / PP system is the most commonly used. There are many studies on this system, especially the comprehensive performance of EPDM / PP system elastomer has been continuously improved through dynamic vulcanization, and various elastomer products with good mechanical properties and excellent resilience have been put on the market.
