Abstract

The invention discloses semi-dull master batch, which is prepared from the following components in parts by weight: 85 to 90 parts of polypropylene terpolymer, 24 to 28 parts of high-density polyethylene, 0.3 to 0.5 part of zinc stearate, 0.01 to 0.02 part of nano magnesium oxide and 0.2 to 0.5 part of a solubilizer. The preparation method of the semi-dull master batch comprises the steps of burdening, mixing all the raw materials in a mixer for 10-15 minutes, melting and extruding the raw materials into strips by virtue of a double-screw extruder and a filter, quickly cooling in a water bath, drying, granulating, separating impurities, sucking into a material tank, performing secondary drying in the material tank to obtain a granular finished product, and putting the granular finished product into an isolated plastic bag to obtain the semi-dull master batch. A semi-dull film prepared from the semi-dull master batch is good in dispersing performance, and the production stability is improved.

Description

technical field [0001] The invention relates to the field of a semi-dull masterbatch, in particular to a semi-dull masterbatch and a preparation method thereof. Background technique [0002] Since the biaxially oriented polypropylene film (BOPP film) was developed in the last century, it has been widely used in our production and life due to its large output and good product performance. Matting film is a type of BOPP film, and the output and performance of the product are also constantly improving. As the most important functional raw material for matting film, matting material directly affects the appearance and feel of the film. At present, the haze of the matting film on the market is basically above 70, which is called full matting film, while the matting film with a haze lower than 60 (generally called semi-dull film) has fewer customers and demands, which leads to the development of such semi-dull materials. It is also relatively lagging, and the performance of the s...
