Problems solved by technology
[0005] When the existing polyurethane raw materials are mixed, a large amount of mixing will be carried out at one time to increase the production rate and ensure the production volume. In this case, other chemicals added to improve the properties of polyurethane will also increase, and they will be added in proportion The proportion of chemical agents is not large, but the dosage is large, which will make it difficult for the agents to mix under a large amount of raw materials, increasing the mixing time and difficulty

The invention relates to the technical field of polyurethane mixing devices, in particular to a polyurethane insulation board raw material mixing treatment system which comprises a stirring box. Supporting legs are fixedly mounted at the four bottom corners of the stirring box, and a protective shell is fixedly mounted at the bottom center of the stirring box; a motor is fixedly mounted in the protective shell; and an output shaft of the motor penetrates through a bottom plate and a top plate of the stirring box, and extends to the position above the stirring box. According to the mixing treatment system, by using an adding mechanism, chemical agents can be periodically dropwise added into the stirring box, and therefore the chemical agents cannot be accumulated and condensed together; then, the chemical agents are better and faster mixed into polyurethane raw materials, and the discharging amount of the chemical agents every time is adjusted through an adjusting mechanism; by using a control mechanism, and in combination with the adjusting mechanism, the total amount of the chemical agents in operation of the device each time can be controlled, and therefore the chemical agents meet the requirement; and the content of the chemical agents in a storage bottle can be seen through a colored cover and a color plate so as to remind a user to add the chemical agents.
Description
technical field [0001] The invention relates to the technical field of polyurethane mixing devices, in particular to a raw material mixing and processing system for polyurethane insulation boards. Background technique [0002] Polyurethane (PU), the full name of polyurethane, is a polymer compound. It was produced by Otto Bayer and others in 1837. Polyurethane has two types: polyester type and polyether type. They can be made into polyurethane plastics (mainly foamed plastics), polyurethane fiber (called spandex in China), polyurethane rubber and elastomer. Material A and material B are mixed, and other chemical additives are added to them according to production needs and mixed uniformly, and the existing equipment will be used to mix them. [0003] Existing patent (notification number: CN212819373U), this utility model discloses a modified polyurethane surface treatment agent mixing device, which belongs to the technical field of polyurethane material synthesis, includin...
