Abstract

The invention discloses a one coat paint prepared by an organic and inorganic compound emulsion and a preparation method thereof. The one coat paint is used for sealing and decorating an exterior wall. The one coat paint comprises the following components: pure water, a thickener, multifunctional additives, a dispersant, a wetting agent, a defoaming agent, a mildew-proof agent, rutile type titanium dioxide, a filler, a liquid filler, the compound emulsion, film-forming additives, a cosolvent and a fungicide. The one coat paint disclosed by the invention has the performances of a primer paint, namely excellent alkali burnout resistance and salting-out resistance; furthermore, all the performances are in line with the requirements of primer paint first-grade products for the exterior wall of buildings. The one coat paint further has the performances of a finish paint of the exterior wall: a paint film has excellent contrast ratio, scrub resistance, weatherability and stain resistance, and all the performances are in line with the requirements of high-grade products of latex paint for the exterior walls of the buildings.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an organic-inorganic composite latex-based paint and a preparation method thereof. The organic is polyacrylate, and the inorganic is nano-scale SiO. 2 , the emulsion is nano-SiO 2 Modified polyacrylate composite emulsion. Background technique [0002] At present, with the increasing number of building decoration exterior wall materials, the construction cost increases. For example: in 2007, the state promulgated the operation standard of JG / T210-2007 "primer for building interior and exterior walls" and in 2009 the introduction of the operation standard of JG / T157-2009 "putty for building exterior". Application and performance of putties and primers. But not paying attention to the root causes of pan-alkaline and blooming, especially the bonding strength of dry powder putty on the exterior wall is mainly provided by cement and other substances, so its pan-alkaline...
