Abstract

The invention discloses an antibacterial anti-aging refrigerator door sealing strip and a preparation method thereof. The antibacterial anti-aging refrigerator door sealing strip is prepared from a soft polyvinyl chloride jacket and a magnetic rubber strip, wherein the soft polyvinyl chloride jacket is prepared from the following raw materials: polyvinyl fluoride, acrylonitrile-butadiene-styrene copolymer, 24-28 parts of polyurethane resin, epoxy resin, glass fiber, glass cotton, ceramic fiber, calcium carbonate, graphite, polydiethyl terephthalate, a light stabilizer, an inorganic antibacterial agent, a plasticizer and an antioxidant; the magnetic rubber strip is prepared from the following raw materials: rubber, magnetic powder, calcium carbonate and graphite. The preparation method comprises the following steps: (S1) preparing the soft polyvinyl chloride jacket; (S2) preparing the magnetic rubber strip; (S3) tucking the magnetic rubber strip in the soft polyvinyl chloride jacket, and welding at an opening to obtain a primary finished product; (S4) soaking the primary finished product in antibacterial liquid for 48-56 h, and drying to obtain the antibacterial anti-aging refrigerator door sealing strip. According to the antibacterial anti-aging refrigerator door sealing strip and the preparation method thereof disclosed by the invention, the preparation process is simple and practical, the antibacterial anti-aging refrigerator door sealing strip is suitable for large-range popularization and application, and the raw materials are widely available.

Description

technical field [0001] The invention relates to the technical field of refrigerator accessories, in particular to an antibacterial and aging-resistant refrigerator door seal and a preparation method thereof. Background technique [0002] The refrigerator door seal is a kind of refrigerator accessory used for sealing between the refrigerator door and the box body. It consists of two parts, one is a soft polyvinyl chloride (SPVC) coat, and the other is a magnetic strip. It is to prevent the heat exchange between the cold air in the refrigerator and the hot air outside, ensure the freshness of the refrigerator, and prolong the service life of the refrigerator. After the refrigerator has been used for a period of time, the surface of the refrigerator door seal will become dirty, breeding bacteria, mold and other harmful microorganisms, contaminating the stored food, and posing a serious threat to human health. Moreover, the mechanical strength of the refrigerator door seal is lo...
