Polypropylene composite material with high surface hydrophilicity and preparation method and application thereof

The invention provides a polypropylene composite material with high surface hydrophilicity and a preparation method and application thereof. The composite material comprises the following components in parts by weight: 55-85 parts of polypropylene resin; 10-40 parts of glass fiber; 1-20 parts of a first hydrophilic modifier; more than 0 and less than or equal to 5 parts of a second hydrophilic modifier; 0-7 parts of other functional additives; the weight-average molecular weight of the first hydrophilic modifier is 50000-200000, and the first hydrophilic modifier is a polymer containing carboxyl, hydroxyl, acylamino or ester group; and the second hydrophilic modifier is a C5-C50 alkyl oligomer which has the weight-average molecular weight of 500-10000 and contains carboxyl, hydroxyl, acylamino or ester group. According to the composite material, through the synergistic effect of the first hydrophilic modifier and the second hydrophilic modifier, the requirement for preparing a plastic hand mold can be met, th
