Problems solved by technology

[0003] However, most of the cpp films currently on the market are only devoted to the study of their mechanical properties such as tear resistance, and there are very few studies on their antibacterial and antiseptic properties. In fact, cpp films can also be used for packaging good food materials due to their wide application Use, so it is easy to breed bacteria, if the plastic material has poor tolerance to bacteria, it is easy to accelerate the growth of bacteria; therefore, it is necessary to study the antibacterial properties of cpp films

Abstract

The invention discloses a bacteriostatic environment-friendly film and a preparation method thereof. The environment-friendly film is prepared from the following raw materials by weight: 1-2 parts ofsilane coupling agent kh560, 49-50 parts of tetrabutyl titanate, 30-40 parts of methanol, 1-2 parts of bis[tetrakis(hydroxymethyl)phosphonium]sulfate solution, 8-11 parts of isocyanuric acid, 1-2 parts of ethylene bisstearamide, 110-140 parts of high density polypropylene, 2-3 parts of diisocyanate, and 10-12 parts of N-methylpyrrolidine. According to the bacteriostatic environment-friendly film and the preparation method thereof, quaternization reaction is carried out by blending a phosphate-modified sol solution and a silane-polypropylene alcohol solution, thereby effectively improving the bacteriostatic performance and flexibility of the finished film, and the film provided by the invention has high mechanical stability, good uniformity and high quality.

Description

technical field [0001] The invention belongs to the field of environment-friendly films, and in particular relates to an antibacterial and environment-friendly film and a preparation method thereof. Background technique [0002] CPP is a polypropylene (PP) film produced by a cast extrusion process in the plastics industry. This type of film is different from BOPP (bidirectional polypropylene) film, which is a non-oriented film. Strictly speaking, CPP films only have a certain orientation in the machine direction (MD) direction, mainly due to the nature of the process. Excellent clarity and smoothness formed on the film by rapid cooling on chilled rolls; lower cost and higher yield compared to other films such as LLDPE, LDPE, HDPE, PET, PVG, etc. Its advantages are many: Compared with PE Film stiffness is higher. Excellent moisture and odor barrier properties. Multi-functional, can be used as composite base film. Metallization is possible. As food and commodity packagin...
