Description

Compound colour metal flash paint and compound method thereof

The present invention relates to a kind of paint, be specifically related to a kind of compound colour metal flash paint and compound method thereof.

The high finish paint materials of decorating of steel and iron member surface treatment are present domestic mainly containing, amine baking varnish (A04-9) series, acrylic enamel (B04-5) series, thermosetting polyester series, two component polyurethane series, and in various varnish, add coloring metal powder material etc.Though use these materials that certain advantage is arranged, abundant as paint film, gloss is high, tint retention good, water-fast, oil resistant etc., but it is undesirable and use the condition of producer to be limited to every performance of painting composition material, the problem that enamelled coating exists as needs baking, low, the easy contamination of hardness, protect light, guarantor's look, plentiful, development degree and assortment on automobile all less than imported auto.[Japanese Patent is open] JP05-194882 Taikoku kako Cltd-1993.8.3-6 page or leaf-92/8692 (1992.1.21) IPC C09D5/38 discloses a kind of metallized coating composition, the topic that can form the weathering resistance decorative coveringn is stated composition and is contained fine metal oxide particles and the resin that Ti sheet powder coats with the oxide compound or the oxyhydroxide of 〉=a kind of element (being selected from Zr, Al, Si), as containing the MT500HD (TiO that coats with the oxide compound of Zr and Al ₂Particle), the composition of 4 7-712 (bright olefin(e) acid polymkeric substance), L11T (melamine resin), M350 (Ti sheet powder) and toluene, dimethylbenzene, vinyl acetate between to for plastic is sprayed on the plate of primary coat dry then being coated with the varnish cover.This luster coating and aforesaid paint vehicle exist equally needs baking, the single problem of assortment.

The object of the present invention is to provide a kind of compound colour metal flash paint and compound method thereof, it can produce a series of bright in luster and be graceful chromatic metallic flash of light lacquer painting effect by comparatively simple compound method and coating process.

Technical solution of the present invention is as described below:

One, ratio of components

Base-material: urethane enamel paint 5-30%
