The antibacterial low temperature-resistant heat insulation material comprises, by weight, 10-25 parts of LDPE resin, 5-10 parts of modified melamine resin, 20-30 parts of an antibacterial agent, 15- silicone rubber, 20-30 parts of ethylene propylene rubber, 15-25 parts of butadiene rubber, 10-20 parts of styrene butadiene rubber, 3-5 parts of aromatic oil, 1-3 parts of stearic acid, 2-4 parts of a coupling agent, 5-8 parts of a compatibilizer, 10-15 parts of a foaming agent, 5-20 parts of a filler, 1-2 parts of an antioxidant, 1-3 parts of an antioxidant, 3-7 parts of a plasticizer, 5-10 parts of paprika, 5-10 parts of a mildew inhibiotor, 15-25 parts of high-low temperature resistance carbon black, 3-5 parts of nanometer calcium carbonate, 5-15 parts of glass fibers, 5-15 parts of ceramic fibers, 20-35 parts of a flame retardant, 5-10 parts of methylvinyldimethoxysilane and 10-15 parts of kaolin. The antibacterial low temperature-resistant heat insulation material has the advantages of good heat and cold resistance, excellent heat insulation performance, excellent mechanical properties and strong antibacterial property.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an antibacterial low temperature resistant thermal insulation material. Background technique [0002] For a long time, polyurethane foam has been widely used in low-temperature environments such as refrigerators, containers, freezers, and pipelines due to its light weight, low thermal conductivity, and high specific strength. , cold and heat preservation, etc.; however, in the reaction of polyurethane materials, freon is used, which may cause damage to the atmospheric ozone layer and fail to meet the requirements of international environmental protection organizations; at the same time, because polyurethane materials contain nutrients necessary for bacteria and molds, Under suitable temperature and humidity conditions, microorganisms (bacteria and mold) will multiply in large numbers, and mold secretions will cause biodegradation of materials. With the improv...

[0002] For a long time, polyurethane foam has been widely used in low-temperature environments such as refrigerators, containers, freezers, and pipelines due to its light weight, low thermal conductivity, and high specific strength. , cold and heat preservation, etc.; however, in the reaction of polyurethane materials, freon is used, which may cause damage to the atmospheric ozone layer and fail to meet the requirements of international environmental protection organizations; at the same time, because polyurethane materials contain nutrients necessary for bacteria and molds, Under suitable temperature and humidity conditions, microorganisms (bacteria and mold) will multiply in large numbers, and mold secretions will cause biodegradation of materials. With the improvement of people's living standards, more and more fields have put forward the hygienic performance of materials. Higher requirements, so it is necessary to endow insulation materials with antibacterial properties, and it is necessary to select and use new insulation materials
