Problems solved by technology

If a protective layer is applied on top of this topcoat, although it can improve the surface effect, it will require four or more coats and the application will be more complicated
CN100441645C discloses "a kind of nitro-crack paint and its preparation method and use conditions" although the effect is better than traditional crack paint, but the higher volatile organic compounds are not friendly to the environment,

Abstract

The invention relates to a preparation of fluorine-containing water-based crackle paint and coating method thereof. The fluorine-containing water-based crackle paint is composed of water-based epoxy primer and water-based fluorine-containing finish paint. Paint, filler and auxiliary are added to a sand mill according to percentages by weight to be grinded to be less than or equal to 40 microns; epoxy resin is added for homogeneous mixing to constitute the water-based epoxy primer; paint, filler and auxiliary are added to water according to percentages by weight to be grinded to be less than or equal to 40 microns after stirring, and are then mixed with fluorine-containing resin emulsion to constitute the water-based fluorine-containing finish paint. The coating method is as follows: the water-based epoxy primer is brush-coated or spray-coated on a substrate, and the thickness of dry film of the water-based primer is controlled; after the surface of the dry film is dry, the water-based fluorine-containing finish paint is spray-coated on the epoxy primer. Compared with the prior art, the fluorine-containing water-based crackle paint has lower content of volatile organic compound, no pollution for the environment, no poison for operating staff, excellent coating performance, strong adhesive attraction, water logging resistance, scrub resistance, simple preparation technology, convenient operation and low cost.

Description

Technical field: [0001] The invention relates to an art paint, especially a fluorine-containing water-based paint, especially the preparation and coating method of the fluorine-containing water-based crack paint. Background technique: [0002] Crackle paint is a kind of art paint, which is made of nitrocellulose, pigments, fillers and solvents. In the formula, there are few film substances, many pigments and fillers, and the solvent is highly volatile. With common nitro varnish as bottom layer, also cover light with nitro varnish sometimes in order to protect cracked paint layer. Nitro dyes, which have -NO in the chromogenic system 2 A class of dyes, except for those containing nitro-NO 2 In addition, it usually contains -OH or -SO at the same time 3 H. Ruoamic acid is one of the earliest nitro dyes. There are not many varieties, mainly acid dyes, yellow dyes, and a few disperse dyes. [0003] Crackle paint is mainly used for artworks and handicrafts, and is also used ...
