Antistatic matt film and preparation method thereof

Abstract

The invention discloses an antistatic matt film and a preparation method thereof. The antistatic matt film is of a three-layer structure and sequentially comprises an anti-adhesion layer, a core layerand a matt layer from top to bottom; the anti-adhesion layer is prepared from the following raw materials in parts by weight: 80 to 90 parts of polypropylene and 1 to 3 parts of an anti-adhesion agent; the core layer is prepared from the following raw materials in parts by weight: 80 to 90 parts of polypropylene and 2 to 4 parts of antistatic agent; the matt layer is prepared from the following raw materials in parts by weight: 90 to 96 parts of matt master batch and 2 to 3 parts of slipping agent; the three-layer structure of the antistatic matt film is formed by melt co-extrusion and two-way stretching. The matt film prepared by the invention has the advantages of few crystal points and white points on the film surface, higher haze and lower glossiness, smooth and fine hand feeling of the matt layer and more attractive white matte effect, can be used for protecting the surface of an electronic product, plays a role in preventing dust and scratching the electronic product in the production process, and is also suitable for being used as an outer package of a high-end commodity.

Description

technical field [0001] The invention relates to the field of film production, in particular to an antistatic matting film and a preparation method thereof. Background technique [0002] Biaxially oriented polypropylene film (BOPP) has good physical stability, high mechanical strength, good air tightness, high transparency and gloss, and is tough and wear-resistant. It is the most widely used film, and its general thickness is 10-100 μm. At present, biaxially oriented polypropylene film is divided into two categories: glossy film and matte film. Matte film can be divided into single-sided matte, double-sided matte and heat-sealed matte. The successful development of matting film has greatly expanded the application range of the film. However, due to different raw materials and different production equipment, the production parameters also need to be constantly explored. The matting films on the market generally have problems such as poor dispersion, white spots on the film s...

Problems solved by technology

However, due to different raw materials and different production equipment, the production parameters also need to be constantly explored. The matting films on the market generally have problems such as poor dispersion, white spots on the film surface, and many crystal points. The quality of the product also needs to be further improved.
