Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane coating production equipment, in particular to a polyurethane coating reaction kettle. Background Art

[0002] Two-component polyurethane coatings are generally composed of isocyanate prepolymers (also called low molecular weight urethane polymers) and hydroxyl-containing resins, which are usually called curing agent components and main agent components. There are many varieties of this type of coatings, and the application range is also very wide. According to the different hydroxyl-containing components, they can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane and other varieties. In the production process of polyurethane coatings, a reactor is required.

[0003] The existing polyurethane coating reactor accelerates the reaction rate of the added materials by stirring during use, so as to ensure the reaction effect of the materials. In the above method, since the stirring shaft is fixed during the stirring process, the materials usually submerge the highest stirring rod on the stirring shaft, which results in the material above the stirring rod being unable to be stirred, resulting in the material being unable to be fully stirred, affecting the stirring effect of the device. At the same time, the material remaining on the stirring shaft cannot be discharged during the discharge process, affecting the recovery rate of the material after the reaction. Therefore, a polyurethane coating reactor is urgently needed to solve the above problems. Utility Model Content
