[0002] Polyurethane structural adhesive refers to an adhesive that is used in bonding load-bearing structural parts, can withstand large dynamic loads, static loads and can be used for a long time. It can not only be used for bonding plastics and metals, but is also widely used for bonding other materials, as well as for automobile assembly, and has been extended to industrial fields such as construction and machinery.

[0003] During the production process of polyurethane structural adhesive, other additives need to be added, so various raw materials need to be fully stirred and mixed. For example, a raw material mixing device for the production of high-performance polyurethane structural adhesive with application number CN 218981318U includes a mixing tank. By arranging a threaded rod, a threaded sleeve, a stirring plate, a support rod, a connecting rod, a stirring blade and a first motor, various raw materials can be fully mixed and stirred.

[0004] The above utility model has the following shortcomings: since the material of the polyurethane structural adhesive itself has great viscosity, it is easy to adhere to the tank body when the raw materials are mixed, resulting in that the various raw materials for producing the polyurethane structural adhesive cannot be fully mixed and need to be repeatedly processed, which greatly reduces the mixing processing efficiency of the polyurethane structural adhesive. At the same time, the loss rate of the raw materials is high, and the production cost increases accordingly. Utility Model Content
