Abstract

The invention discloses a preparation method of emulsion for low-solid-content high-quality interior wall latex paint. The emulsion for the low-solid-content high-quality interior wall latex paint is prepared from an emulsifying liquid and an initiator, wherein the initiator comprises a first initiator and a second initiator. The preparation method comprises the following steps: S1, sequentially adding water, an emulsifying agent, completely dissolved sodium bicarbonate, acrylamide, acrylic acid, butyl acrylate, styrene and flushing water into an emulsifying tank, and emulsifying for later use to obtain the emulsifier. According to the invention, the solid content in the emulsion is reduced to about 43% from about 47% in the prior art, the national qualified product standard is met, the cost is reduced, and the market competitiveness is enhanced.

Description

technical field [0001] The invention relates to the technical field of latex paint, in particular to a method for preparing an emulsion for interior wall latex paint with low solid content and high quality. Background technique [0002] Emulsion paint is a common name for emulsion 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. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. The interior wall latex paint is a classification of latex paint, which is a kind of paint for interior decoration. [0003] Existing interior wall latex paint formulas interior wall latex paint...
