Abstract
The invention provides a washable interior wall emulsion, a preparation method, application and a washable interior wall coating thereof, and relates to the technical field of interior wall coatings. The invention solves the technical problem that the washing resistance of the paint is difficult to obviously improve in the prior art, and achieves the technical effect that the inner wall paint has excellent washing resistance and greatly improves the defect that the existing inner wall paint is not scrubbing resistant.
Description
Technical Field
The invention relates to the technical field of interior wall coating, in particular to a washable interior wall emulsion, a preparation method and application thereof, and a washable interior wall coating.
Background
The interior wall coating is the coating variety with the largest application amount of the building coating, and compared with the exterior wall coating, the interior wall coating has few varieties, the main film forming substance is acrylic ester or synthetic resin copolymerized with vinyl monomers, most of the interior wall coating is styrene-acrylic emulsion and pure acrylic emulsion, and a small amount of the interior wall coating is tertiary ethylene carbonate-vinyl acetate copolymer emulsion and the like. Acrylic polymers are widely used because of the excellent light and color retention, chemical stability and the like, but have the problems of low adhesion to wall substrates, poor water resistance, poor alkali resistance and hot adhesion and cold brittleness.
The interior wall latex paint is prepared by taking polymer emulsion as a film forming material, taking synthetic resin emulsion as a base material, adding pigment, filler and various auxiliary agents; the interior wall emulsion paint is one of the main decorative materials of indoor wall surfaces and ceilings, and has the characteristics of good decorative effect, convenient construction, little environmental pollution, low cost and wide application. However, latex paints on the market are generally not resistant to scrubbing.
The existing washable interior wall coating mostly solves the problem of washability by improving the compactness of a paint film and changing the friction coefficient and reducing the comprehensive mode of the hydrophilic coefficient of a system in an organic-inorganic combination mode, but cannot obviously improve the washability.
In view of this, the present invention has been made.
Disclosure of Invention
The invention aims to provide a preparation method of a washable interior wall emulsion, which has the advantages of simple process and convenient operation, and can obtain the styrene-acrylic interior wall emulsion with low Tg and high washability, wherein the emulsion polymerization stability, the particle size and the stability of the finished emulsion are both considered.

Comparative example 3
The comparative example differs from example 1 in that the silica particles added in step 3 of the comparative example had a diameter of 120nm, and the remaining steps and the process parameters thereof were referred to example 1 to obtain an interior wall emulsion.
Since the composite particles formed of the larger diameter silica particles also have a larger diameter, the inner wall emulsion of this comparative example has a disadvantage in that the gloss and film forming property of the emulsion are lowered as compared with example 1.
