Abstract

The invention relates to the field of painting technologies, in particular to a paining process of an aqueous multicolor paint used for CCA (cellulose fiber-cement sheet) boards. The painting process comprises the following steps: processing materials, spraying fluorocarbon white primers, spraying water-texture intermediate paints, spraying aqueous multicolor paints and spraying fluorocarbon transparent finish coats. The painting process is simple and quick in operation and low in cost. A product which is painted has the advantages of good weather resistance, high hardness and the like. The painting process is especially used for painting outdoor CCA boards to achieve artificial granite and marble effects.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a coating process of water-based colorful paint for CCA boards. Background technique [0002] CCA board is a pressurized or non-pressurized flat plate of autoclaved, asbestos-free, cellulose fiber reinforced cement, which is the abbreviation of Cellulose fiber-Cement sheets, Autoclaved in English. As a green environmental protection and energy-saving material, CCA board is suitable for a variety of construction fields with its superior characteristics; such as outdoor table tops, doors, cabinets, wardrobes, etc. However, the appearance of the original CCA board is ordinary, and it is necessary to develop a coating and a coating process suitable for outdoor CCA desktop board coating according to customer requirements, so as to achieve the purpose of decoration and protection. [0003] Water-based colorful paint, because its coating has special properties such as concave and conve...
