Talcum powder master batch and preparation method thereof

The invention relates to a talcum powder master batch and a preparation method thereof. The talcum powder master batch is prepared from the following raw materials in parts by weight: 11-30 parts of polypropylene, 3-10 parts of a compatilizer, 5-10 parts of a siloxane master batch, 60-70 parts of talcum powder, and 0.3-0.6 parts of an anti-oxidant, wherein the compatilizer is formed by polyolefinresin and dialkyl-terminated amino silicon oil; and the polyolefin resin is a copolymer of propylene and ethylene. The polyolefin resin is specifically selected to be combined with the dialkyl-terminated amino silicon oil, the effect of the compatilizer is achieved, and good infiltrating and coating effects are realized for the talcum powder. Dispersion of the talcum powder in PP resin is improved, scratch resistance is improved, and a dosage of the siloxane master batch can be reduced, so rigidity of a material can be further improved, and cost is reduced under the precondition of the good scratch resistance. 本发明涉及种滑
