Abstract

The invention provides a flame retardant polyurethane composition, a flame retardant polyurethane foam material and a method for preparing the same. The flame retardant polyurethane composition comprises a first component and a second component, wherein the first component comprises organic polyhydric alcohols, silicone oil, foaming agent, catalyst, ethylene monomer which contains hydroxyl, initiator, 2,2',6,6'-tetrabromobisphenol A diallyl ether and trichloroethyl phosphate; and the second component comprises polyisocyanates. Because the ethylene monomer which contains hydroxyl and the initiator are added in the flame retardant polyurethane composition, during the foaming process, the hydroxyl of the ethylene monomer which contains hydroxyl and isocyanate group are reacted with each other to form carbamate bond, meanwhile, the ethylene unsaturated bond and the unsaturated end group of the 2,2',6,6'-tetrabromobisphenol A diallyl ether are subjected to free radical polymerization under the action of the initiator, finally, the 2,2',6,6'-tetrabromobisphenol A diallyl ether is connected into the polyurethane cross-linked network structure in a chemical bond mode, so in the final flame retardant polyurethane foam material, the 2,2',6,6'-tetrabromobisphenol A diallyl ether plays the role of reactive flame retardant, and the obtained foam material has a better flame-retardant effect.

Description

technical field [0001] The invention relates to a flame-retardant polyurethane composition, a flame-retardant polyurethane material and a preparation method thereof, belonging to the field of flame-retardant foam materials. Background technique [0002] Polyurethane foam is the largest variety of polyurethane synthetic materials, and its total output accounts for about 60% of polyurethane materials. Among them, rigid polyurethane foam is mainly used in the heat insulation layer of household appliances, roof insulation and waterproof spray foam, pipe insulation materials, building panels, refrigerated vehicles and cold storage insulation materials, etc. With the continuous expansion of the application range, it is increasingly recognized that it is extremely important to improve the flame retardancy of polyurethane foam materials. Therefore, the development and application of flame-retardant rigid polyurethane foam has become an important topic in the field of polyurethane f...
