High-fluidity PP cooling master batch and preparation method thereof

The invention relates to a high-fluidity PP cooling master batch and a preparation method thereof, and the high-fluidity PP cooling master batch comprises the following raw materials by weight: 92-97 parts of PP resin, 1-6 parts of a composite dispersant, 3-8 parts of a mineral filling mixture, 0.5-1 part of a flow promoter, 0.5-1.5 parts of a vulcanizing agent, 1-5 parts of a molecular weight regulator, and 0.2-2 parts of an antioxidant. Wherein the mineral filling mixture is formed by mixing talcum powder and calcium carbonate. The preparation method of the high-flowability PP cooling master batch comprises the following steps: step 1, mixing raw materials of the high-flowability PP cooling master batch according to a material ratio to obtain a mixture; and 2, carrying out melting granulation on the mixture. The cooling device has the beneficial effect of being good in cooling performance. The flowability and cooling performance of the existing PP cooling master batch are improved by selecting the materials
