Problems solved by technology

The biggest shortcoming of rigid foamed plastics in the prior art is that the average core density is high, at 35~40Kg/m 3 , and the high average core density will lead to the deficiencies in the following three aspects: First, the consumption of raw materials such as polyurethane rigid foam composites and isocyanates for the production of foamed plastics is large, which not only causes unreasonable waste of raw materials, but also It leads to an ineffective increase in cost; the second is that the high average core density will produce high thermal conductivity, so that the foamed foam has

Description

technical field [0001] The invention relates to the technical field of foamed plastics, in particular to polyurethane foamed plastics for solar water heaters and applications thereof. Background technique [0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard. As known in the industry, polyurethane rigid foam is widely used in water heaters, refrigerators, pipes and buildings, etc., and plays the role of heat insulation and sound resistance, while polyurethane rigid foam is formed by the reaction of polyurethane rigid foam composite material and isocyanate People are also used to refer to polyurethane rigid foam as polyurethane foam or polymer synthetic material. The biggest shortcoming of rigid foamed plastics in the prior art is that the average core density is high, at 35~40Kg / m 3 , and the high average core density will lead to the deficiencies...
