Document Type and Number:
WIPO Patent Application WO/2022/000432
Kind Code:
A1
Abstract:
The present invention discloses an environment-friendly fiber impregnation treatment system based on a two-bath process, a preparation method therefor and an application thereof. The system comprises a one-bath impregnation solution and a two-bath impregnation solution, wherein the one-bath impregnation solution comprises a phenolic compound A and water or comprises the phenolic compound A, a filler, and water; the two-bath impregnation solution comprises an epoxy resin, an amine compound, rubber latex, and deionized water. The impregnation treatment system can be used for preparing impregnated fiber fabric. According to the impregnated fiber fabric prepared by the environment-friendly fiber impregnation treatment system based on the two-bath process provided in the present invention, the performance of adhesion between fiber and rubber is slightly superior to impregnated fiber fabric treated by an RFL system, change in the tensile strength of the fiber is small, and the comprehensive effect exceeds the impregnated fiber fabric treated by the RFL system.
