Abstract
The invention discloses a high-transparency self-adhesive film which is prepared from the following raw materials: high-pressure low-density polyethylene, polybutyl methacrylate, nano cellulose, a water-based cross-linked alkyd resin emulsion, modified talcum powder, modified montmorillonite, epoxidized soybean oil, poly (butylene succinate), modified nylon, a plasticizer, a stabilizer and an antioxidant. By adding the high-pressure low-density polyethylene, the high-transparency self-adhesive film has good chemical stability, good dielectric property, thermal stability, toughness, impact resistance, high transparency and like. The modified talcpowder and the modified montmorillonite are added and achieve a synergistic interaction effect, so that more raw materials are uniformly dispersed in the network structure formed by the modified talcpowder and the modified montmorillonite, the physical and mechanical properties of the film can be significantly improved, and therefore, the film has good elongation at break, toughness and tensile strength. The added epoxidized soybean oil can improve the stability of the film to light and heat. The physical and mechanical properties of the film are further improved by adding the modified nylon. The film has a wide market prospect.
Description
technical field [0001] The invention relates to the technical field of self-adhesive films, in particular to a highly transparent self-adhesive film and a processing method thereof. Background technique [0002] Self-adhesive film is a kind of protective film without glue and self-adhesive. It has various colors such as transparent film, blue film, milky white film, black and white film, etc. It is a protective film especially suitable for the surface of high-end products. There are mainly three production methods: extrusioncoating, co-extrusioncasting, and co-extrusion blown film. [0003] The drawstring strength and tear strength of the existing self-adhesive films still need to be further improved in order to meet more and more usage requirements. Contents of the invention [0004] Embodiments of the present invention aim to provide a highly transparent self-adhesive film and its processing method to solve the above problems. [0005] To achieve the above object, th...
