Description
Technical Field
The invention relates to the technical field of plastic films, in particular to application of a compound slipping agent in an anti-sticking master batch, an anti-sticking master batch for a polyolefin film, a preparation method and a film thereof.
Background
With the development of socioeconomic performance, the technological innovation speed of plastic packaging films is increasing, and the materials, technologies, equipment and final products are continuously updated. All manufacturers strive to catch up with the advanced foreign levels in the aspects of brand establishment and product quality improvement. The polyolefin film is a polymer film with the widest output and application, and is widely applied to the fields of food packaging, medicine packaging, daily chemical packaging and the like. However, the thin film has a relatively smooth surface, and the blocking phenomenon occurs under the action of pressure and static electricity during production and storage, thereby affecting daily use and use in an industrial automatic packaging production line.
The anti-adhesion technology at present mainly adopts slipping agent and opening agent for anti-adhesion modification. The slipping agent is formed by using incompatibility between the slipping agent and polyolefin and transferring the slipping agent from the interior of the film to the surface of the film to form a thin layer, so that the surface of the film is smooth, the friction coefficient of the surface of the film is reduced, and the slipping performance of the film is improved. The opening agent is mainly inorganic powder, and small bulges are formed on the surfaces of the films by utilizing the opening agent, so that air can enter gaps among the films, and the air pressure among the films is balanced, and the films can be opened easily. However, the erucamide or silicone mainly used at present belongs to a slipping agent with easy migration, so that the transparency of the film and the composite strength of the film are easily influenced, and the slipping effect is easily lost due to too fast migration. The opening agent is most commonly used at present, and is powder such as silicon dioxide, talcum powder and the like, and the haze of the film is greatly influenced.
