Technical Field
The invention relates to the technical field of polyurethane materials, in particular to a polyurethane foam composition, polyurethane foam and a preparation method thereof.
Background
The rigid polyurethane foam is a high molecular polymer prepared by mixing isocyanate and polyether serving as main raw materials through special equipment under the action of various auxiliary agents such as a foaming agent, a catalyst, a flame retardant and the like and performing high-pressure spraying and on-site foaming. Polyurethane has both soft and hard foams. The soft bubbles are in an open pore structure, and the hard bubbles are in a closed pore structure; soft foams are classified into skinned and non-skinned. The primary function of the polyurethane soft foam is cushioning. Polyurethane flexible foams are commonly used in sofa furniture, pillows, cushions, toys, apparel and sound insulation liners. The polyurethane rigid foam is a novel synthetic material with heat-insulating and waterproof functions, has low heat conductivity coefficient, is only 0.022-0.033W/(m × K), is equivalent to half of an extruded sheet, and has the lowest heat conductivity coefficient in all heat-insulating materials. The hard polyurethane foam plastic is mainly applied to heat preservation of building outer walls, integration of roof waterproof and heat preservation, heat preservation and insulation of cold storages, pipeline heat preservation materials, building boards, refrigerated trucks, heat insulation materials of cold storages and the like.
However, the existing raw materials for preparing the polyurethane foam have poor stability and cannot be placed for a long time, so that the normal foaming cannot be realized, and the cost is increased.
