Background technique

Polyurethane rigid foam is mainly used for household appliance insulation layer, house wall insulation waterproof spray foam, pipe insulation material, building board, refrigerated truck and cold storage insulation material; in recent years, along with building energy conservation in energy saving system engineering Continuously improve, and in building energy conservation, the heat (cold) of the building's retaining structure is more than 50% of the total building loss, and the wall in the retaining structure accounts for 2/3. Therefore, the wall insulation should be It is an important part of building energy conservation. Due to its excellent physical properties and its special processing and application characteristics, polyurethane rigid foam has been increasing its application share in the building energy-saving market. Polyurethane rigid insulation board is the most excellent insulation building material and has convenient installation. It can avoid or reduce maintenance costs during use, and is widely used in building insulation.

At the same time, the Ministry of Construction's polyurethane energy-saving application promotion working group released the "Technical Guidelines for Exterior Wall Thermal Insulation of Polyurethane Rigid Foam System" to regulate the work of further promoting polyurethane exterior wall insulation system. The huge building insulation market is gradually being opened, polyurethane Energy-saving insulation boards have encountered unprecedented development opportunities. The state plans to complete the energy-saving renovation of all buildings in the country by 2020. It is predicted that more than 150 million m ² of polyurethane energy-saving insulation boards will be needed each year, which has a huge market.

At present, the domestic production of polyurethane insulation board is made of polyurethane hard block foam produced by batch method. This method is small in production and far from meeting the demand of China's building energy-saving market. Therefore, the production of polyurethane rigid block is a bottleneck. The domestic production of polyurethane hard block foam uses iron box mold as a mold, and the A and B component raw materials are foamed by a foaming machine or manual stirring into a mold. The main problems are: low production capacity, high labor, high labor intensity, low degree of automation, and difficult quality control, which is not conducive to scale production, and the performance of foam is far less than that of continuous foaming.
