Problems solved by technology

The patent clearly stated that the welding tension of general TPE materials is poor, which affects the transportation and use of door seals, and the raw materials used to improve welding performance are mainly POE plastics and PP elastomers
Since the SEBS elastomer used in this patent is less, but mainly a large amount of POE plastic and PP elastomer, the door seal has poor elasticity and strong plasticity, and the door seal is not easy to recover after deformation, and the advantages of TPE door seal are not fully utilized

Abstract

The invention relates to a thermoplastic elastomer door seal easy to weld. The door seal is prepared from, by weight, 40-55 parts of SEBS elastomers, 5-15 parts of tackifying resin, 10-15 parts of filler, 5-15 parts of processing oil, 10-15 parts of polypropylene, 1-2 parts of lubricating agent, 0.1-1 part of pigment, 0.1-0.5 part of antibacterial and antifungal agent, 0.1-0.5 part of antioxidant and 0.1-0.5 part of ultraviolet light absorber. The invention further provides a preparation method of the thermoplastic elastomer door seal. The thermoplastic elastomer door seal easy to weld is high in welding strength and good in rebound elasticity, still keeps the good elasticity in the low-temperature application environment such as refrigerators and other refrigeration appliances, prevents a flash seam from being produced, can better close the gap between a door body and a box body, reduces electric appliance energy consumption and makes a contribution to further energy conservation of the refrigeration appliances.

Description

technical field [0001] The invention belongs to the technical field of door seal materials, and in particular relates to an easily weldable thermoplastic elastomer (TPE) door seal for refrigerators, freezers, wine cabinets and other refrigeration appliances and a preparation method thereof. Background technique [0002] At the end of September 2015, the National Standardization Management Committee issued a new version of the refrigerator energy efficiency standard GB 12021.2-2015 "Limited Values ​​of Electricity Consumption and Energy Efficiency Levels of Household Refrigerators" (hereinafter referred to as the new standard), which is used to replace GB 12021.2-2008 and was released in 2016. It was officially implemented on October 1, 2019. The new standard stipulates that the power consumption of energy efficiency level 1 products is about 40% lower than that of the original energy efficiency level 1 products. However, the proportion of refrigerators with energy efficienc...
