Problems solved by technology

The shape of the particles is irregular, and the opening effect is general. During the processing, agglomeration is prone to occur, which makes the distribution of particles uneven on the surface of the film, which not only affects the continuity of production, but also has poor haze uniformity of the film, and the haze of the film is relatively low. Big

Abstract

The invention discloses a high-dispersity BOPETopening smooth master batch and a preparation method thereof, and relates to the technical field of plastics, the high-dispersity BOPET opening smooth master batch is prepared by blending and extruding the following components in parts by weight: 90-94% of a component A, 3-5% of a component B and 3-5% of a component C, wherein the component A is prepared from the following raw materials in parts by weight through a polymerization reaction: 3-4% of nano porous silicon dioxide, 42-44% of purified terephthalic acid, 52-54% of ethylene glycol and 0.08-0.12% of an auxiliary agent; the component B is prepared from the following raw materials in parts by weight: 45-50% of siloxane and 50-55% of spherical porous silicon dioxide; and the component C isone or more of erucyl amide, calcium stearate and stearyl trimethyl ammonium chloride. According to the invention, the binding force between the nano-porous silicon dioxide particles and the base material is improved; the phenomenon of poor appearance caused by falling of silicon dioxide particles on the surface of a film is reduced, meanwhile, the dispersity of the particles is improved, a certain smooth effect is achieved, and the film prepared by adding the master batch is good in opening effect, small in static electricity, uniform in haze and good in transparency.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a high-dispersibility BOPET opening smooth masterbatch and a preparation method thereof. Background technique [0002] Plastic films are easy to stick and difficult to open. Therefore, an opening smoothing agent is often added in the production and preparation of plastic film products, which can effectively improve the opening performance of the film. The earliest anti-blocking agents were inorganic talcum powder, diatomaceous earth, etc.; in the mid-term, organic oleic acid amide, erucamide and EBS derivatives were developed; at present, synthetic silica is widely used as anti-blocking agent in thin films. [0003] At present, in the production process of biaxially oriented films, especially biaxially oriented polyester films, the commonly used anti-blocking agent is amorphous silicon. The shape of the particles is irregular, and the opening effect is general. During the proce...
