Hybrid emulsion, water-based inorganic coating prepared from hybrid emulsion and preparation methods of hybrid emulsion and water-based inorganic coating

Abstract

The invention relates to a hybrid emulsion, a water-based inorganic coating prepared from the hybrid emulsion and preparation methods of the hybrid emulsion and water-based inorganic coating. The water-based inorganic coating is mainly prepared from the following components in parts by weight: 40-70 parts of water, 0.4-20 parts of mixed monomers, 1-10 parts of potassium persulfate aqueous solution, 0.001-1 part of anionic emulsifier AS30, 0.001-1 part of tert-butyl hydroperoxide, 0.001-1 part of FF6M reducing agent, 1-10 parts of ethyl orthosilicate, 0.1-15 parts of gamma-glycidyl ether oxypropyltrimethoxysilane, and 0.1-5 parts of concentrated ammonia water. The defects that a paint film of an existing water-based inorganic coating for interior walls easily generates cracks, micropores and the like, and has the defects of poor scrubbing resistance, poor water resistance and the like. Organic-inorganic hybrid particles are used as main film forming substances, the organic matter part ensures that a formed film does not crack, and the introduction of the inorganic matter silicon dioxide endows the emulsion with the advantages of scrubbing resistance, water resistance, good storage stability and the like.

Description

technical field [0001] The invention relates to a hybrid emulsion, a water-based inorganic paint prepared from the hybrid emulsion and a preparation method thereof, which are applied in the field of paint production. Background technique [0002] Water-based interior wall inorganic paint refers to the preparation of alkali metal silicate and emulsion as the main binder, combined with inorganic mineral pigments and inorganic mineral fillers. It is formed on buildings by brushing, spraying or rolling. Thin decorative coating, and it does not contain harmful substances such as formaldehyde, volatile organic compounds, heavy metals, etc., and is widely applicable to the coating process of existing building walls. Although water-based inorganic coatings are environmentally friendly and safe, most of them use silicate or silica sol as the main film-forming substance, which makes the volume of water-based inorganic coatings shrink greatly during the film-forming process, and the fo...
