General coating and preparation method for preparing light-color and dark-color general coating

Abstract

The invention discloses a general coating and a preparation method for preparing a light-color and dark-color general coating. The general coating comprises the following components by weight percent: 10-18% of water, 0.3-3% of texanol, 0.35-3% of propylene glycol, 0.05-0.5% of organic silicon, 0.05-1% of polycarboxylic ammonium, 0.05-1.1% of isothiazolinone, 0.05-1.1% of sodium alkylarylsulfonate, 0.1-0.5% of cellulose, 0-30% of titanium dioxide, 5-35% of acrylate emulsion, 5-35% of acrylic emulsion, 0.24-1% of polyacrylate, 5-36% of modified talcum powder and 0-20% of color paste. The general coating provided by the invention is suitable for the substrate surface decoration of indoor and outdoor concrete structures, bamboo structure and steel structure and has the advantages of excellent weather fastness, pollution resistance, brushing resistance, wide application scope, simple preparation method, easiness in production and easiness in popularization.

Problems solved by technology

[0003] Due to the small scope of application of existing decorative coatings, they cannot be used universally for the surface decoration of substrates with different structures such as concrete structures, bamboo and wood structures, and steel structures, and are also difficult to be used outdoors and indoors; so when using decorative coatings to decorate the surface of buildings It is necessary to consider the structure of the base material on the surface of the building, and whether it is used indoors or outdoors. The corresponding coating should be selected according to the structure of the base material and the application occasion. As a result, different coatings and tools need to be replaced frequently during the construction process, and the construction work is heavy. low efficiency
