Abstract

The invention discloses heat-resistant modified polypropylene film master batch and a preparation method thereof. The master batch comprises raw materials in parts by mass as follows: 78-80 parts of polypropylene, 18-21 parts of linear low density polyethylene, 1-3 parts of light calcium carbonate, 0.4-0.6 part of oxidized polyethylene and 0.6-0.8 part of tertiary butyl hydroquinone. According to the preparation method, the polypropylene is modified, and the linear low density polyethylene, the light calcium carbonate, the oxidized polyethylene and the tertiary butyl hydroquinone are compounded, so that the obtained polypropylene master batch has excellent heat resistance, the obtained master batch is subjected to two-way stretch to form a film, and the film is good in heat resistance, shrinkage deformation can be avoided during heat sealing.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a heat-resistant modified polypropylene film masterbatch and a preparation method thereof. Background technique [0002] The most common type of polypropylene film is biaxially oriented polypropylene film. Biaxially oriented polypropylene film is generally a multi-layer co-extruded film. After co-extruding polypropylene particles to form a sheet, it is stretched in both vertical and horizontal directions. And made. This film has good physical stability and high transparency and gloss, and is currently a widely used film. However, its heat resistance is not good, and it is easy to shrink and deform when heat sealing. Therefore, it is particularly important to modify the existing polypropylene film. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the prior art. Contents of the invention [0004] T...
