Description

Technical Field

[0001] The utility model relates to the technical field of waterborne polyurethane resin production equipment, in particular to a stirring device for waterborne polyurethane resin production. Background Art

[0002] Waterborne polyurethane resin refers to polyurethane with water as the dispersion medium. The basic use of waterborne polyurethane is as a leather finishing agent. Polyurethane resin is flexible and wear-resistant, and can be used as a coating agent and repair agent for natural leather and artificial leather. Waterborne polyurethane finishing agents overcome the weaknesses of acrylic emulsion finishing agents such as "hot sticky and cold brittle". The leather treated with it feels soft, smooth, plump, and shiny, with a strong sense of genuine leather, which can greatly improve the grade of leather goods and enhance market competitiveness. During the production process of waterborne polyurethane resin, a stirring device is required for stirring.

[0003] At present, in the use of waterborne polyurethane resin stirring devices, since most of the waterborne polyurethane resin stirring devices are driven by motors to rotate and stir the stirring blades in a fixed direction inside the stirring device, it is not convenient to adjust the position and direction of the stirring blades inside the stirring device, the stirring efficiency is low, and it is not convenient to use. At the same time, during the stirring process of the existing waterborne polyurethane resin, it is not convenient to introduce the bottom layer of waterborne polyurethane resin into the upper layer for mixing, and stratification is prone to occur, resulting in poor overall stirring effect of the waterborne polyurethane resin and reduced use efficiency of the waterborne polyurethane resin stirring device.
