Abstract

The invention discloses an ultralow GWP eco-friendly engineering spraying polyurethane thermal insulation material and a preparation method thereof. The ultralow GWP eco-friendly engineering spraying polyurethane thermal insulation material comprises multiple components I and a component II according to a weight part ratio. The components I comprise 20-30 parts by weight of low-viscosity high-functionality degree polyether polyol A, 10-30 parts by weight of low-hydroxyl value high-functionality degree polyether polyol B, 30-50 parts by weight of an aromatic hydrocarbon-type low-viscosity flame-retardant polyester polyol C, 10-30 parts by weight of a phosphorus-containing fire retardant, 20-30 parts by weight of a phosphorus-containing halogen fire retardant, 1-3 parts by weight of a foam stabilizer, 4-8 parts by weight of a catalyst, 1-3 parts by weight of water and 10-20 parts by weight of a low-GWP eco-friendly LBA foaming agent. The component II is polyaryl polymethylene isocyanate. The invention relates to a preparation method of the thermal insulation material. The thermal insulation material has performances the same to those of a product obtained through a 141B foaming agent. In production, gas produced through foaming agent volatilization has ultralow GWP and zero ODP characteristics.

Description

technical field [0001] The invention relates to the field of polyurethane preparation, in particular to an ultra-low GWP environment-friendly engineering spray polyurethane thermal insulation material and a preparation method. Background technique [0002] Polyurethane rigid foam is a new type of synthetic material with thermal insulation and waterproof functions. Its thermal conductivity is only 0.020-0.025W / (m*Κ), which is the lowest among all thermal insulation materials at present. Therefore, rigid polyurethane foam is used to replace traditional thermal insulation materials. It is mainly used in building exterior wall insulation, roof waterproof and thermal insulation integration, cold storage thermal insulation, pipeline thermal insulation materials, building panels, refrigerated vehicles and cold storage insulation materials, etc. It has become one of the thermal insulation and energy-saving products that dominate the market. [0003] The advantages of polyurethane s...
