Abstract

The invention relates to a composite material for an ultrathin low-conductivity stainless steel kitchen cabinet and a preparation method of the composite material, and belongs to the technical field of polyurethane. The composite material comprises a component A and a component B, the mass ratio of the component A to the component B is 1: (1.15-1.3), and the component A comprises 10-30% of polyether polyol A, 20-40% of polyether polyol B, 15-35% of polyether polyol C, 3-8% of polyether polyol D, 3-5% of polyester polyol, 2-3% of a foam stabilizer, 1.5-2.5% of water, 1.5-2% of a composite catalyst, 9-12% of a C5 foaming agent, 4-6% of an HFC / HFO foaming agent and 1-3% of a C4 foaming agent. The composite material provided by the invention has excellent fluidity and low-temperature dimensional stability, and the rigid polyurethane foam prepared from the composite material has good dimensional stability, higher compression strength and lower heat conductivity coefficient, and is energy-saving, consumption-reducing and environment-friendly; the invention also provides a simple and feasible preparation method.

Description

technical field [0001] The invention relates to a combination material for ultra-thin and low-conductivity stainless steel kitchen cabinets and a preparation method thereof, belonging to the technical field of polyurethane. Background technique [0002] Polyurethane rigid foam is an excellent thermal insulation material, coupled with its excellent mechanical strength and processability, makes polyurethane rigid foam have a very wide range of applications. For stainless steel kitchen cabinets, the constant pursuit of large volume and the increasingly complex internal structure have put forward more stringent requirements for low density and low thermal conductivity of foam materials. [0003] The density of the conventional polyurethane foam system is still high, which cannot meet the pursuit of small volume and large volume in the cabinet industry, so further optimization and improvement are needed. Contents of the invention [0004] The technical problem to be solved by ...
