Abstract

The invention relates to polyester elastomer composition and a preparation method thereof, which belongs to the chemical industry technology field. The composition comprises components with following proportion by weight: 60-100 parts of polyester elastomer, 0.01-10 parts of epoxy compound, 0-10 parts of poly carbodiimide compound, 0-5 parts of acid anhydride grafting body, 0-40 parts of toughened high polymer compound, 0-3 parts of nucleating agent, 0-5 parts of compatiblizing agent, and 0.1-1 part of antioxidant. The components are evenly mixed by adopting a high speed mixer, then the extrusion granulation is performed through a double screw, the combined properties of the prepared polyester elastomer composition are fine, and the high and low temperature impact properties under the high modulus are outstanding.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to polyester containing polyester elastomer epoxy compound, polycarbodiimide compound, acid anhydride graft, toughening polymer compound, nucleating agent, compatibilizer and antioxidant Elastomer composition. Background technique [0002] Polyester elastomer is obtained by copolymerization of dibasic carboxylic acid, diol and aliphatic polyether (such as polyalkylene ether glycol) or aliphatic polycarbonate, and its Shore hardness range is 30-75D. As an engineering Grade elastomers have excellent physical and mechanical properties, such as toughness, fatigue resistance, high strength, wear resistance and chlorine resistance, so their usage has been increasing in recent years. [0003] However, in the application of plastics, under some conditions, the processed products of the elastomer are required to have excellent hydrolysis resistance, heat resistance, high and low t...
