摘要（英）：

The invention discloses a glass fiber reinforced, dynamic vulcanized and scratch resistant type polypropylene compound and a preparation method thereof. The glass fiber reinforced, dynamic vulcanized and scratch resistant type polypropylene compound comprises the following components in percentage by weight: 9 to 64 parts of polypropylene, 30 to 55 parts of ethylene propylene diene monomer, 0 to 1 part of processing aid, 0 to 10 parts of vulcanizing agent, 1 to 5 parts of glass fiber compatilizer, and 5 to 20 parts of glass fibers. The glass fiber reinforced, dynamic vulcanized and scratch resistant type polypropylene compound is remarkable in scratch resistance, high in comprehensive mechanical performance, lower in shrinkage percentage and higher in heat deflection temperature; the scratch resistance DL is less than or equal to 0.5 (4N), the tensile strength is not less than 18MPa, the flexural modulus is not less than 1700MPa, the notch impact strength at normal temperature is not less than 45kJ/m<2>, the notch impact strength at low temperature is not less than 20kJ/m<2>, and the heat deflection temperature (0.45MPa) is not less than 120 DEG C. The glass fiber reinforced, dynamic vulcanized and scratch resistant type polypropylene compound can be used for molding inner decorative components of an automobile requiring the scratch resistance, such as an automobile instrument board, a door board and a vertical post, and is great in touch and lower in glossiness.
