Powder emulsion paint for interior wall

Abstract

The invention relates to a powder emulsion paint for an interior wall, comprising the following components by weight percent: 25-35% of re-dispersible crylic acid rubber powder, 2-3% of polyving akohol, 15-20% of triple superphosphate, 10-15% of nanometer calcium carbonate, 14-20% of titanium white, 6-10% of lithopone, 4-6% of kaolin, 0.5-2% attapulgite, 0.5-1% of sodium polyacrylate, 0.5-0.8% of hydroxyethyl cellulose, 0.1-0.23% of sodium dodecyl benzene sulfonate, 0.24-0.4% of lauryl sodium sulfate, 0.15-0.5% of sodium tripolyphosphate, 0.6-0.8% of fatty alcohol-polyoxyethylene ether, and 0.01-0.05% of sodium hydroxide. The invention has no organic solvent; porous nanometer filler can be used for absorbing indoor harmful substance; the invention can be stored for a long time without any deterioration or precipitation; and the powder dispersed by water can be emulsified into an emulsion paint state, and the powder can be prepared into different use concentrations based on construction requirements.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a latex paint, especially a powder interior wall latex paint. Background technique [0002] Latex paint is a common name for synthetic resin emulsion paint. Resins that can be dissolved in water to form a uniform colloidal solution are called water-soluble resins. It is called latex when it is dispersed in water to form an emulsion with fine resin particle clusters (particle diameter 0.1-1.0 μm). [0003] As we all know, the basic components of latex paint include: [0004] (1) Film-forming substances, general polymer synthetic resin emulsion, also known as polymer emulsion; [0005] (2) Pigments and fillers, which mainly endow latex paint with properties such as color, hardness, and water resistance after film formation; [0006] (3) Various additives, mainly to improve the quality of latex paint such as storage stability, workability and various index performances of the p...

Problems solved by technology

[0006] (3) Various additives, mainly to improve the quality of latex paint such as storage stability, workability and various index performance of the paint film. At present, the improvement of latex paint mainly focuses on the selection and dosage of additives. The choice of additives is used to improve the quality of latex paint, but the existence of a large number of additives has certain pollution to the environment. This is because many additives contain formaldehyde, benzene, etc. as preservatives, which make latex paint contain harmful substances

In addition to the above-mentioned disadvantages, the existing latex paint products also have the disadvantages of short storage period, easy precipitation, easy deterioration, non-freezing resistance, high packaging and transportation costs, and can only be brushed and sprayed during construction.
