Abstract

The invention provides a base latex coating for an interior wall. The base latex coating comprises the following components in part by weight: 8 to 20 parts of water, 2 to 4 parts of cosolvent, 0.5 to 1.2 parts of dispersant, 0.1 to 0.25 part of wetting agent, 0 to 40 parts of pigment, 0 to 65 parts of filler, 8 to 70 parts of emulsion, 0.2 to 1 part of thickener and 0.1 to 0.4 part of defoaming agent. The invention also provides a preparation method for the base latex coating for the interior wall. According to the method, the material adding sequence and mixing conditions are specified. The base latex coating for the interior wall has the advantages of water resistance and alkali resistance, can keep good performance under the action of ultraviolet, has functional characteristics of freezing and thawing resistance and the like, is nontoxic, has low content of volatile organic compounds (VOC), can meet the application requirement of the interior wall at present, and has an active environment-friendly significance.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical coatings, and particularly relates to a latex base paint for interior walls and a preparation method thereof. 【Background technique】 [0002] In developed countries in Europe and the United States, the penetration rate of water-based paint has reached more than 80%. But in our country, the development of water-based paint is just on the highway. Although it is still in a weak position, its share is growing rapidly. In the near future, water-based paints will occupy the mainstream paint market. The main advantages of water-based paints are: 1. Environmentally friendly oil-based paints are mainly nitro paints and polyester paints. A large amount of organic solvents are added during the dilution process, and they stay indoors for a long time, which will cause harm to human health. Therefore, oil-based paint has also been dubbed the title of "invisible killer". It was found that a larger part of ...
