Problems solved by technology

But this kind of latex paint is relatively harsh on the wall. If the old wall is refurbished, the substrate will be slightly uneven, and the light will show uneven luster. Therefore, the construction requirements are relatively high, and the construction requires a lot of work. Meticulous, otherwise it will be difficult to show its elegant, delicate and delicate effect

Abstract

The invention discloses modified general type emulsion paint and a preparation method thereof. The preparation method comprises the following steps: preparation of white paste, preparation of base stock and preparation of emulsion paint. According to the modified emulsion paint disclosed by the invention, ASE and HUER thickening systems are respectively adopted to combine with CPA and KPA dispersing agents, so that the produced emulsion paint cannot generate a bad phenomenon in the storage process as the dosage of the dispersing agents is increased. In addition, the CPA and KPA dispersing agents are respectively mixed and matched with MC35 and PU40 thickening agents so as to enable low, medium and high shearing viscosity to become more balanced, so that the glossiness is smooth after a wall surface is painted, and the requirement on construction is reduced as well.

Description

technical field [0001] The invention relates to the design of a decorative material, in particular to a modified general-purpose latex paint and a preparation method thereof. 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 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. General-purpose latex paint represents a large class of general-purpose latex paint, which is suitable for different consumption levels and is currently the product with the largest market share. The most common is matte latex paint, which has a white effect and no luster. Clean and tidy, with a certain degree of scrub resistance and good hiding power. The typical one is a silk wall paint, which f...
