Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to polyurethane rigid foam spraying equipment. Background Art

[0002] Polyurethane rigid foam is a high molecular polymer, mainly made of isocyanate and polyether as the main raw materials. It is mixed in special equipment by adding various additives such as foaming agent, catalyst, flame retardant, etc., and foamed on site by high-pressure spraying. This material has many excellent properties, including good insulation effect, light weight, high specific strength, convenient construction, etc., and also has the characteristics of sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, and solvent resistance. Most polyurethane rigid foams are closed-cell structures, which helps to improve the thermal insulation performance of the material. Due to its low thermal conductivity (0.022~0.033W / (m·Κ)), polyurethane rigid foam is widely used in the insulation layer of refrigerators and freezers, cold storage, refrigerated trucks and other insulation materials, as well as insulation materials for buildings, storage tanks and pipelines. In addition, polyurethane rigid foam is also used to make materials for non-insulating occasions, such as imitation wood and packaging materials. Lower density polyurethane rigid foam is mainly used as insulation (thermal insulation) material, while higher density can be used as structural material (imitation wood). The wide application of this material is due to its excellent physical and chemical properties, making it an indispensable material in many fields. When spraying polyurethane, the polyurethane must be heated first and then sprayed after it is heated evenly. The appearance and color requirements of the spraying surface are different.

[0003] Most of the existing polyurethane spraying equipment requires manual operation with a handheld spray nozzle to spray polyurethane on roofs or flat ground. It is not only inconvenient to use, but also easily causes polyurethane to stick to the body, affecting the health of workers. In addition, most of the existing polyurethane, when sprayed after heating, often has uneven foaming or internal impurities blocking the spray port, resulting in poor polyurethane spraying effect, affecting the construction period, and making maintenance and use inconvenient.
