Abstract

The invention discloses a manufacturing process of antibacterial plastic for a storage interlayer of a refrigerator. The antibacterial plastic is prepared from the following raw materials in parts by weight: 80-100 parts of polypropylene resin, 30-50 parts of ethylene propylene diene monomer rubber, 5-8 parts of a dispersing agent, 8-10 parts of an antibacterial agent, 12-15 parts of frost-proof reinforcing liquid, 15-20 parts of epoxidized soybean oil and 5-8 parts of kaolin powder. The antibacterial agent can cause reduction of permeability of cell membranes, leakage of bacterial cell sap, denaturation of bacterial protein and prevention of bacterial metabolism so as to kill bacteria, meanwhile, the antibacterial agent is high in relative molecular mass and not easy to separate out from the surface of the interlayer, and the frost-proof reinforcing liquid can prevent the surface of the interlayer from frosting after the interlayer is used for a long time, so that the frosting phenomenon cannot happen on the surface, meanwhile, the surface contains a large number of imide structures, so that the reinforcing filler contains a large number of ether bonds, the toughness of the antibacterial plastic is further improved, and stored objects are prevented from scratching the partition plate and influencing normal use of the partition plate in the use process of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to an antibacterial plastic manufacturing process for storage compartments of refrigerators. Background technique [0002] With the improvement of people's living standards, refrigerators have become one of the necessary daily necessities for families in people's daily life. The box is also called the shell, which can be divided into aluminum, steel, glass and plastic according to the types of materials that make up the shell. Among them, the plastic material with cheap and easy-to-obtain raw materials, low production cost and simple production method is the main body. It can be said that More than 80% of the refrigerators in our daily life use plastic shells. In order to increase the space utilization rate inside the refrigerator, partitions are often added inside. [0003] During the long-term storage of items, the refrigerator partitions are prone to bacterial growth...
