A kind of production method of latex paint

Abstract

The invention belongs to the technical field of paint production, in particular to a production method of latex paint. The method adopts a grinding device, and the grinding device includes a cylinder; it also includes a hollow shaft, an upper grinding disc, a lower grinding disc, a collection box and a driving unit; An upper millstone and a lower millstone are arranged inside the barrel; the upper millstone is located above the lower millstone; the lower millstone is connected to a drive unit, and the drive unit is used to drive the lower millstone to cooperate with the upper millstone for grinding. The water-based paint is initially crushed by the grinding ball, and then the drive unit drives the lower millstone to move up and down and left and right. The upper millstone and the lower millstone cooperate with each other to fully grind the water-based paint, thereby improving the grinding efficiency of the water-based paint; The paint is cleaned from the No. 1 grinding disc, so as not to affect the grinding of the water-based paint in the later stage, so as to improve the grinding effect of the water-based paint.

Description

technical field [0001] The invention belongs to the technical field of paint production, in particular to a production method of latex paint. Background technique [0002] Latex paint is a common name for latex paint. It was born in the middle and late seventies of the 20th century. It is a large class of synthetic resin emulsion paint represented by acrylate copolymer emulsion. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. [0003] In the production and preparation of polymer water-based coatings, grinding the coating is an essential and important process. In the prior art, when the paint is ground, the paint is put into a grinding barrel with grinding media for grinding; but the existing grinding method has the following defects: the grinding media is easy to wear out, the service life is short, and it cannot be ground for a long time. Continuous work...

Problems solved by technology

In the prior art, when the paint is ground, the paint is put into a grinding barrel with grinding media for grinding; but the existing grinding method has the following defects: the grinding media is easy to wear out, the service life is short, and it cannot be ground for a long time. Continuous work; due to the lack of primary crushing of the paint when feeding, some paint particles entering the grinding chamber are relatively large, which is not conducive to fully grinding the paint, so the quality of the grinded paint is also relatively poor

However, the grinding of the water-based paint in this technical solution is insufficient, and the water-based paint after grinding is easy to adhere to the grinding disc, thereby affecting the grinding effect; making this technical solution limited
