Problems solved by technology

At present, the hardness of the PET substrate used for coating and coating is low, generally hovering between 2-3H, which can easily cause scratches on both sides of the PET film, which has a great impact on the back-end process, and the antibacterial property is poor, making the product The quality is greatly reduced, the cost is increased, and the hardness of the BOPET film is low, resulting in its non-wear and scratch resistance, which also makes it unsuitable for the increasingly popular flexible cover or as a screen explosion-proof film

Abstract

The invention discloses a wear-resistant scratch-resistant antibacterial BOPET film. The film is composed of a surface layer A, a core layer B and a bottom layer C. A thickness ratio of the surface layer A to the core layer B to the bottom layer C is (2-5): (20-40): (2-5); the surface layer A and the bottom layer C are located on the two sides of the core layer B; the surface layer A is an antibacterial layer; the core layer B is a filling layer; and the bottom layer C is wear-resistant scratch-resistant layer; The surface layer A comprises the following raw materials: PET slices, a compositeantibacterial agent, a catalyst and a stabilizer. The core layer B is a PCTG copolyester slices. The bottom layer C comprises the following raw materials: PET slices, a toughening agent, a KH550 silane coupling agent, a functional additive, a catalyst and a stabilizer. The invention also discloses a preparation method of the wear-resistant scratch-resistant antibacterial BOPET film. The BOPET filmprepared by the invention has the advantages of wear resistance, scratch resistance, lasting antibacterial property; and the method is simple in production process, wide in raw material sources and low in production cost.

Description

Technical field [0001] The invention belongs to the technical field of plastic film manufacturing, and specifically relates to a wear-resistant, scratch-resistant and antibacterial BOPET film and a preparation method thereof. Background technique [0002] BOPET film is a more comprehensive packaging film. It has good transparency and luster; it has good air tightness and fragrance retention. BOPET film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, its tensile strength and impact strength are much higher than ordinary films, and it has good stiffness and stable dimensions. It is suitable for secondary processing such as printing and paper bags. BOPET film has excellent cold resistance and good chemical resistance and oil resistance. [0003] In recent years, the BOPET film industry has developed rapidly, the industry's market applications have continued to expand, the degree of professionalism of products has become higher, ...
