Background
The aqueous coating is a coating using water as a solvent or as a dispersion medium. In the production of aqueous paints, it was found that the paint contained bubbles of a size after thickening. The bubbles with large volume are large bubbles and the bubbles with small volume are micro bubbles, and the phenomenon often occurs in thick slurry type coatings such as elastic napping. After the aqueous coating film is dried, pinholes or miliaria are caused by bubbles, the appearance of the coating film is affected, and defoaming is generally carried out by using a defoaming agent. However, the traditional defoaming agent has low defoaming speed, low efficiency, simple defoaming process and incomplete defoaming in the use process; meanwhile, in the production process of the water-based paint, more foam is usually generated due to the fact that raw materials are higher in viscosity, so that volume expansion is caused, the utilization rate of blending equipment is reduced, and therefore a related defoaming device is generally used for removing foam in the paint. At present, the most common defoaming equipment adopts a mechanical rotation mode to foam the paint, the defoaming mode can remove foams with larger volume, the foams cannot be thoroughly removed, and new small foams can be produced in the rotation process, so that the defoaming effect is poor.
