Title:
POLYPROPYLENE COMPOSITE MATERIAL HAVING HIGH SURFACE HYDROPHILICITY, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/001201
Kind Code:
A1
Abstract:
A polypropylene composite material having high surface hydrophilicity, and a preparation method therefor and an application thereof. The composite material comprises the following components in parts by weight: polypropylene resin: 55-85 parts; glass fiber: 10-40 parts; a first hydrophilic modifier: 1-20 parts; a second hydrophilic modifier: greater than 0 part and less than or equal to 5 parts; and other functional additives: 0-7 parts. The first hydrophilic modifier is a polymer having a weight average molecular weight of 50,000 to 200,000 and containing a carboxyl group, a hydroxyl group, an amide group, or an ester group. The second hydrophilic modifier is a C5-C20 alkyl oligomer having a weight average molecular weight of 500-10,000 and containing a carboxyl group, a hydroxyl group, an amide group, or an ester group. The composite material has a synergistic effect of the first hydrophilic modifier and the second hydrophilic modifier, so that the preparation of a plastic hand mold can be satisfied, the yield and the service life are greatly improved, the yield of gloves is greater than or equal to 97%, and the service life reaches over 2 years.
