Title:
COMPOSITE MATERIAL OF OCTADECYLDIMETHYL-TERTIARY-AMINE-MODIFIED ZEOLITE AND NATURAL RUBBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/003760
Kind Code:
A1
Abstract:
Disclosed are a composite material of an octadecyldimethyl-tertiary-amine-modified zeolite and a natural rubber and a preparation method therefor, and the present invention belongs to the field of non-metal mineral materials. The method involves first subjecting a natural zeolite to wet ultra-fine grinding, adjusting the pH value of a zeolite mineral paste to 6-10, mixing same with a salt solution in which octadecyldimethyl tertiary amine is completely dissolved, subjecting same to wet modification at 40-100°C for 5-60 min, and drying and grinding the modified product to obtain an octadecyldimethyl-tertiary-amine-modified zeolite; and adding the octadecyldimethyl-tertiary-amine-modified zeolite to a rubber formulation, and mixing and vulcanizing same to obtain a composite material of the octadecyldimethyl-tertiary-amine-modified zeolite and a rubber. The method involves subjecting the surface of a natural zeolite to organic modification and mixing the modified zeolite with a natural rubber, and can significantly increase the mechanical properties of the natural rubber.
