Abstract

The invention discloses an anti-stress whitening transparent filling master batch for polypropylene and a preparation method thereof. The baster batch is prepared from the following raw materials in percentage by weight: 15 to 25 percent of polypropylene, 50 to 65 percent of transparent powder, 10 to 15 percent of polysiloxane, 0.5 to 1 percent of nucleating agents, 8 to 10 percent of compatilizers, 0.5 to 1 percent of coupling agents and 0.5 to 1 percent of antioxidants. The raw materials are weighed according to the mixture ratio; the transparent powder is added into a high-speed material mixing machine; the coupling agents are added into the material mixing machine to be mixed with the transparent powder; the polypropylene, the polysiloxane, transparent powder subjected to surface treatment, compatilizers, nucleating agents and antioxidants are sequentially added; stirring is performed so that the materials are uniformly mixed; the mixed materials are added into a double-screw extrusion machine to be extruded into strip-shaped articles; the master batch is obtained after the cooling. The anti-stress whitening transparent filling master batch has the advantages that the product surface smoothness and wear-resistance can be improved; the moisture absorption is avoided; the filling quantity is great; the transparency of the product is not influenced; the product manufacturing cost can be favorably reduced; good application values are realized.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to an anti-stress whitening transparent filler master batch for polypropylene and a preparation method thereof. Background technique [0002] Polypropylene is widely used in the automotive industry, household appliances, electronics, agriculture, construction packaging, and building materials and furniture due to its excellent performance. The development of application fields such as transparent packaging and daily necessities is restricted. After transparent modification, polypropylene PP can not only inherit its advantages of light weight, low price, hygiene, high temperature resistance, and easy processing and molding, but also has the advantages of transparency and surface gloss. Comparable to some other transparent resins (polycarbonate PC, polystyrene PS, etc.), the performance-price ratio is also better than PC, PS, PET, etc., so it can be widely used in transparent packagi...
