Abstract

The invention discloses a self-sterilizing aviation paper-plastic composite garbage bag and a preparation method thereof. The preparation method comprises: (1) pounding raw wood pulp, bamboo leaves, pine leaves and other components, mixing the pounded components and lime water, mixing, cooking to obtain a paper pulp, washing the paper pulp, bleaching, beating, taking out the paper, carrying out pressing drying, and baking the paper to prepare antibacterial paper M1; (2) mixing a polycarbonate resin, a phenol formaldehyde resin and other components, carrying out heat treatment to obtain a melt M2, extruding, molding, and processing to form a film M3; and (3) heating the film M3, coating the surface of the antibacterial paper M1 to form a plastic layer so as to prepare composite paper, and processing the composite paper into the self-sterilizing aviation paper-plastic composite garbage bag. According to the present invention, the prepared self-sterilizing aviation paper-plastic composite garbage bag has advantages of good mechanical strength and good antibacterial performance, such that the long-term sterile use of the garbage bag in aviation can be ensured.

Description

technical field [0001] The invention relates to the field of garbage bags, in particular to a bactericidal aviation paper-plastic composite garbage bag and a preparation method thereof. Background technique [0002] Garbage bags, as the name suggests, are bags for garbage. A small bag brings great convenience to thousands of households, and it also provides an important guarantee for environmental protection, and is even conducive to garbage recycling and classification. According to the classification of materials, garbage bags can be divided into plastic garbage bags and paper garbage bags. Although paper garbage bags are environmentally friendly, they are far inferior to plastic garbage bags in terms of mechanical strength and durability. Large and light weight can also be widely used. [0003] Paper-plastic composite garbage bags are widely used in the aviation field due to their high strength and durability. However, the durability of paper-plastic composite garbage ca...
