The present invention relates to a kind of talcum powder master batch and preparation method thereof.The talcum powder master batch are based on parts by weight of raw materials, including following components: 11-30 parts of polypropylene；3-10 parts of compatilizer；5-10 parts of siloxanes master batch；60-70 parts of talcum powder；0.3-0.6 parts of antioxidant；The compatilizer is made of polyolefin resin and dialkyl capped amido silicon oil；The polyolefin resin is the copolymer of propylene and ethylene.The present invention specifically selects polyolefin resin to be used in combination with dialkyl capped amido silicon oil, it can play the role of compatilizer, there is infiltration and covered effect well to talcum powder, improve dispersion of the talcum powder in PP resin, improve scratch resistant performance, it is possible to reduce the dosage of siloxanes master batch, thus under the premise of with good scratch resistant performance, the rigidity that can further improve material, reduces cost. |
