Problems solved by technology

Therefore, the adhesion, color retention and scrub resistance of interior wall coatings have gradually become important indicators for people to purchase interior wall coatings. Most of the existing coatings have good aesthetics, but they are easy to fall off and will age after a long time. Discoloration, difficult to maintain, therefore, existing paint needs to be retrofitted

Abstract

The invention provides an environment-friendly architectural interior wall coating. The coating comprises the following components in parts by weight: 20 to 25 parts of a titanium dioxide sol; 15 to 20 parts of a synthetic resin emulsion; 10 to 15 parts of zinc oxide; 0.1 to 1 part of a dispersant; 0.05 to 0.1 part of a coupling agent; 1 to 2 parts of a defoaming agent; 0.5 to 1 part of a levelling agent; 0.01 to 0.5 part of a thickener; 1 to 2 parts of a film-forming auxiliary agent; and 30 to 50 parts of water. According to the coating, the synthetic resin emulsion is used as a base material, the titanium dioxide sol and a certain proportion of the functional auxiliary agent are added to prepare the architectural interior wall coating, so that the adhesion and stability of interior wallcoating can be improved, and the coating can effectively catalyze degradation of indoor harmful gases TVOC and formaldehyde, plays a good role in air purification, is beneficial to human health, and has good environmental protection value.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to an environment-friendly architectural interior wall coating and a preparation method thereof. Background technique [0002] The interior wall coatings used in buildings refer to the kind of coatings that not only play a decorative role, but also protect the interior walls. The main raw materials of the early coating industry were natural vegetable oils and natural resins, such as linseed oil, tung oil, rosin, raw lacquer, etc. However, natural resin and paint resources are limited. With the development of the petrochemical industry, various synthetic resins, solvents, and additives have appeared one after another, and they have also developed rapidly as interior wall coatings applied to the surface of buildings. After the 1960s Emulsion-type coating materials based on synthetic resins and synthetic diluents, and even water as diluents, have been developed successiv...
