Preparation and Properties of POM Toughened by Thermoplastic Polyurethane Elastomer

Abstract 锛�The thermoplastic polyurethane (PUR-T) elastomer toughened polyoxymethylene (POM) alloy was prepared by corotating twin screw extruder with self-made maleic anhydride grafted ethylene-methyl acrylate-glycidyl methacrylate random terpolymer as compatibilizer. The difference of crystallization and melting temperature of POM and POM锛�PUR-T was compared by DSC. The effects of PUR-T content and screw combination (shear strength of screw block) under the same PUR-T content on the mechanical锛�friction and wear properties of the alloy were investigated. The results show that锛�the addition of PUR-T reduces the crystallization and melting peak temperature of the alloy. With the increase of PUR-T content锛�the elongation at break and notched impact strength of the alloy increase锛�while the density锛�tensile strength锛�bending strength and bending modulus decrease锛�the friction coefficient and wear loss first decrease and then increase. When the content of PUR-T is 10 phr锛�the comprehensive mechanical锛� friction and wear properties of the alloy are better. The shear strength of screw block has great influence on the mechanical properties of POM锛�PUR-T alloy锛�the stronger the shear strength of screw block is锛�the more obvious the deterioration of mechanical properties is锛�but the shear strength of screw block has little effects on the friction and wear properties of the alloy.
