Abstract

The invention discloses a chlorinated polyether aging-resistant modified material and a preparation method thereof. PVC, 55-75 parts of chlorinated polyether, 0.3-0.8 parts of coupling agent, 0.1-0.3 parts of cross-linking agent, 1-3 parts of ultraviolet absorber, 1-3 parts of antioxidant In the present invention, the nano-calcium carbonate and chlorinated polyether are compounded through targeted modification, and the nano-calcium carbonate is uniformly dispersed in the chlorinated polyether system, and the modified material obtained has excellent aging resistance, which is beneficial to chlorine The application of polyether in more fields.

Description

technical field [0001] The invention relates to the field of modified materials, in particular to a chlorinated polyether aging-resistant modified material and a preparation method thereof. Background technique [0002] The chemical name of chlorinated polyether is poly 3,3'-bis(chloromethyl)butoxy ring, which is prepared by ring-opening polymerization of 3,3'-bis(chloromethyl)butoxy ring monomer in the presence of a catalyst . Chlorinated polyether has high heat resistance, chemical corrosion resistance and wear resistance, and has low water absorption and high mechanical properties. Its products are widely used in machinery, electronics, chemical industry, medical equipment, daily appliances, and office appliances. etc. [0003] With the continuous improvement of people's requirements on the aging resistance of materials, it is difficult for chlorinated polyethers without aging resistance modification to meet the demand. Therefore, it is necessary to carry out aging resi...
