The invention relates to the field of metallic paint preparation, and particularly relates to a true copper metallic combination paint as well as a preparation method and a construction process of the paint preparation. The preparation method specifically comprises the procedure of applying high-anticorrosion epoxy iron red priming paint, true copper paint, true copper black coating stringing paint and true copper surface oil layer by layer on the surface to be constructed. The true copper metallic combination paint comprises four layers of paint, which are constructed and combined artistically and interact with one another, and has the advantages that the copper texture is strong, the anticorrosion property is good, the adhesion force is strong, fading is prevented, and acid, base and greasy dirt can be resisted, the weather-proof performance and the environment friendliness are excellent, and the similarity of the decorative effect of the paint and that of metal copper can reach over 95 percent. The preparation method for the true copper metallic combination paint is reliable, and the construction process is scientific and reasonable and is suitable for large-scale coating operation on a production line.

The invention provides a metal surface protection pre-processing process, which comprises the steps of: firstly, normally degreasing metal workpieces once, then washing by water twice; sand-papering; degreasing and washing by water; coating a silane solution; curing; and coating. The metal workpieces are processed by the process; polyacid film layers are formed on the workpiece surfaces; and the polyacid film layers are dense and uniform and have strong adhesion force with metal bodies, so that the polyacid film layers do not easily drop, and the metal protection efficiency is improved. At the same time, the operation process is environment-friendly and pollution-free.

The invention discloses a falling prevention tile which comprises a glaze face and a laying face. A plurality of grooves are formed in the laying face and are trapezoids, the side length of the lower bottom face of each trapezoid is twice that of the upper bottom face of the trapezoid, both the upper bottom face and the lower bottom face of each trapezoid are squares, and the height of the trapezoids is half the thickness of the falling prevention tile. The falling prevention tile is provided with a steel wire gauze parallel to the laying face, the steel wire gauze is arranged in the half position of the height of the grooves, the distance between every two adjacent steel wires is 0.5-1 cm, meshes of the steel wire gauze are rhombic, and the diameter of the steel wires is 0.05 cm. According to the falling prevention tile, the laying face is provided with the grooves, so that friction force between mortar and the tile is increased; meanwhile, due to the facts that the grooves are trapezoids, and the steel wire gauze parallel to the laying face is arranged in the half position of the height of the grooves, adhesion force between the mortar and the tile can be remarkably increased, and the tile is not prone to falling off; and the grooves are arranged in a clover shape, so that the structure between the tile and the mortar is stable, and the falling possibility of the tile is remarkably reduced.

The invention relates to waterborne fireproof paint and a preparation method thereof. The waterborne fireproof paint is prepared from the following ingredients including 250HBR, TEGO 500, OROTAN 1124,BYK 022, 25-percent ammonium hydroxide, titanium dioxide, ammonium polyphosphate, tripolycyanamide, pentaerythritol, chlorcosane, modified vinyl acetate copolymer emulsion, optical stabilizing agentsBASF 1130 and de-ionized water. According to the preparation method, all ingredients are added into the de-ionized water; a mixture M with the fineness being smaller than 60mu m is obtained; then, the modified vinyl acetate copolymer emulsion and the foaming agents BYK 022 are added; finally, the optical stabilizing agents BASF 1130 are added; a finished product is obtained. The waterborne fireproof paint has the advantages that the fire-resistant time is long; the fire-resistant limit is as long as 180min; the impact resistance can reach 55kg.cm; the toughness is 2mm; the water resistance reaches 255h; the adhesion force is 1 grade. The production cost is reduced; the environment resources are saved.
