Description

Polyurethane varnish reation kettle Technical Field The application belongs to the technical field of varnish production equipment, and particularly relates to a polyurethane varnish reaction kettle. Background In the prior art, polyurethane varnish is a high-performance coating product and is widely applied to the fields of aerospace, transportation, electronic appliances, building decoration and the like. The double-component paint is prepared by taking polyisocyanate and polyol as main raw materials and adopting chemical reaction. In the production process, a reaction kettle is one of key equipment for carrying out the polymerization reaction of polyurethane varnish. In the prior art, in the polyurethane varnish production process, raw materials are required to be uniformly mixed through a stirring assembly so as to ensure that materials produced by the polyurethane varnish have excellent performance and transparency. However, the conventional stirring assembly has the problems that the contact area between the stirring blades and the polyurethane varnish raw material in the reaction kettle is too small, the polyurethane varnish raw material is insufficiently stirred in the stirring process, and the raw material cannot be effectively dispersed or mixed, so that the polyurethane varnish is difficult to maintain a uniform proportion in the production process, and the appearance of the varnish is still turbid, and therefore, in order to improve the dispersion performance of the reaction kettle, improvement on the conventional reaction kettle is urgently needed.
