Abstract
The invention discloses an interior wall coating taking water as a solvent. The interior wall coating comprises the following components in parts by mass: 5-10 parts of a nano film-forming accelerant,10-20 parts of redispersible latex powder, 8-13 parts of a silica gel salt, 8-12 parts of calcium carbonate, 3-20 parts of ground calcium carbonate, 3-15 parts of wollastonite, 3-12 parts of cellulose, 10-20 parts of titanium dioxide, 5-10 parts of a dispersant and 3-10 parts of a defoamer. Apreparation method of the interior wall coating taking water as the solvent comprises the following steps:S1, stirring and mixing the nano film-forming accelerant and other dry powder particles according to the weight ratio; and S2, mixing adry powder composition prepared in the step S1 with water according to a ratio of 1: 1.3-1: 1.7, fully stirring, standing for 30 minutes, and filtering twice for use. The interior wall coatinghas the advantages of no pollution, and strong adhesion, covering power,alkali resistance, scrubbing resistance, water resistance and oil resistance.
Description
technical field [0001] The invention relates to the technical field of interior wall coatings, in particular to an interior wall coating using water as a solvent and a preparation method thereof. Background technique [0002] At present, interior wall paints at home and abroad are mainly latex paints or water-based paints. Its film-forming principle is to use acrylic emulsion as a film-forming substance, and with the help of a film-forming auxiliary agent (alcohol ester twelve), the film-forming of the emulsion is promoted. At the same time, since latex paint or water-based paint is prepared in a liquid state, in order to ensure its good performance, stable state and normal use after a long period of storage, it is necessary to add a pH regulator and a wetting agent during the preparation process. , leveling aids, preservatives, antifreeze and other solvents and additives, these additives become the main source of toxic and harmful substances such as formaldehyde and VOC af...
