Problems solved by technology

At present, the existing door seals rarely use anti-mold and antibacterial agents. Therefore, molds are often produced during the production, transportation, storage, and use of door seals, resulting in a decline in the quality of door seals, affecting appearance, refrigerator use, and even human health and safety.

Abstract

The invention provides a polyvinyl chloride mixture, a door seal, a refrigerating device and a manufacturing method. The polyvinyl chloride mixture comprises the following components in percentage by mass: 40-50% of polyvinyl chloride resin powder, 25-35% of a plasticizer, 2-5% of an auxiliary plasticizer, 3-10% of elastomer, 1.5-2.5% of a thermal stabilizer, 10-20% of inorganic filler, 1-2% of a lubricant and 0.5-1% of an anti-mildew antibacterial agent. Through the technical scheme, adhesion and migration of the door seal between a liner HIPS or ABS and a PCM side plate and a spray plate are effectively improved, resilience and permanent compression deformation of the door seal are improved, twisting, dropping and other problems of the door seal are effectively improved, and durability of the door seal is obviously improved; the door seal has an anti-mildew antibacterial property, so that the quality of the door seal is improved and influence of mildewing of the door seal on a human body is avoided.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a polyvinyl chloride mixture, a door seal, a manufacturing method and a refrigeration device. Background technique [0002] At present, the main material of door seals for refrigerators / freezers is PVC, and then plasticizers, stabilizers, fillers, lubricants, antioxidants, etc. are added to it, and PVC doors are made through mixing, granulation, and extrusion. seal. In the current production, storage, transportation or use of door seals, little attention has been paid to the anti-corrosion and antibacterial functions of door seals. , Mold and other phenomena will appear. During the use of the refrigerator, it will seriously affect the taste and quality of the refrigerator, and even threaten the health and safety of the human body. At present, the existing door seals rarely use anti-mold and antibacterial agents. Therefore, molds are often produced during the production, t...
