Description

Technical Field

[0001] The utility model relates to the technical field of resin processing, in particular to a dissolving device for producing polyurethane resin. Background Technique

[0002] Polyurethane, whose full name is polycarbamate, is a polymer material formed by the polycondensation reaction of polyols and polyisocyanates and has excellent mechanical properties. It has extremely strong plasticity. Using 1,6-hexamethylene diisocyanate and 1,4-butanediol as raw materials, linear polyurethane resin was first synthesized. Several main classifications of polyurethane include polyether type, polyester type, polyimide type, polyurea type, etc. They can be made into materials such as polyurethane plastics, polyurethane fibers, polyurethane rubbers and elastomers. Resin usually refers to a substance that has a softening or melting range when heated. When softened, it has a tendency to flow under the action of external force. At room temperature, it is in a solid state, semi-solid state, and sometimes can also be in a liquid state. In a broad sense, any high-molecular compound that can be used as a raw material for plastic processing is called resin. Its relative molecular weight is uncertain but usually high. At room temperature, it is in a solid state, medium solid state, pseudo-solid state, and sometimes can also be in a liquid state. It has a softening or melting temperature range, has a tendency to flow under the action of external force, and often shows a conchoidal shape when broken. In a broad sense, it refers to a polymer or prepolymer used as a plastic substrate. Generally insoluble in water and soluble in organic solvents. It can be divided into natural resin and synthetic resin according to the source; it can also be divided into thermoplastic resin and thermosetting resin according to the different characteristics of its processing behavior.

[0003] As disclosed in the authorized announcement number CN215782901U, a dissolving device for producing polyurethane resin is disclosed, including: a main body, a heating cavity is arranged inside the main body, an inner shell is arranged inside the heating cavity, a motor is fixedly connected to the middle of the top of the main body, and the output end of the motor sequentially passes through the main body, the heating cavity and the inner shell and is fixedly connected to a movable shaft. A filter screen is threadedly connected to the end of the movable shaft away from the motor, and a stirring rod is welded to the end of the filter screen away from the movable shaft. The utility model has the following advantages: by using the filter screen to filter solid substances, it is avoided that the undissolved solid substances affect the quality of polyurethane resin; by using the heating wire, it is convenient to uniformly heat the inner shell and accelerate the dissolving speed; one end of the air pipe is fixedly connected to a condenser, which is convenient for the condensation and recovery of gas and prevents the inner shell from bursting due to excessive air pressure. A filter pipe is threadedly connected inside the inclined pipe of the device, which is convenient for filtering impurities therein and convenient for the disassembly and cleaning of the filter pipe. However, during its use, the dissolving efficiency is relatively low. For this reason, we propose a dissolving device for producing polyurethane resin to solve the problem of low dissolving efficiency of traditional equipment. Content of the Utility Model
