Title:
METHOD FOR PREPARING INTUMESCENT THERMOPLASTIC POLYURETHANE ELASTOMER PRODUCT
Document Type and Number:
WIPO Patent Application WO/2018/129791
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing an intumescent thermoplastic polyurethane elastomer product, and comprises the following steps: 1) coating a binder: attaching the binder to surfaces of intumescent thermoplastic polyurethane elastomer particles; 2) curing and molding: adding a product which is obtained in step 1) into a molding die and then placing within a vulcanizing machine for mold pressing, curing and molding; 3) cooling and setting: cooling the molding die which is molded in step 2) to obtain the product of the present invention. In the present invention, by means of pre-attaching the binder to the surfaces of the intumescent thermoplastic polyurethane elastomer particles, the ratio of the binder added may be reduced, and properties of the intumescent thermoplastic polyurethane elastomer particles may be used to the maximum extent.
