Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0030] figure 1 It is a structural schematic diagram of the production device of the pasty zinc flake pigment in the specific embodiment of the present invention. Such as figure 1 As shown, the production device includes a grinder 101 , a first solid-liquid separator 102 , a stirring tank 103 , a second solid-liquid separator 104 and a kneader 105 .

[0031] The grinding machine is used to grind the material containing spherical zinc powder, grinding modifier and grinding aid solvent prepared in proportion. The grinding machine is a stirring grinding machine or a drum grinding machine, and the grinding balls are stainless steel balls, alumina balls Or zirconia balls, the diameter of the grinding balls is 1 to 15 mm, preferably 3 to 7 mm, the weight ratio of grinding balls to spherical zinc powder ...

Abstract

The invention discloses a production method and device for a pasty zinc flake pigment. Spherical zinc powder, a grinding modifier and a grinding aid solvent are compounded, the compounded material is put into a grinder for grinding, and the material obtained after grinding is ground. The slurry is sent to the solid-liquid separator for the initial solid-liquid separation to obtain the initial paste zinc flakes, put the initial paste zinc flakes into the mixing tank, add an organic solvent containing a surface modifier, and treat the initial paste zinc flakes surface For modification, send the surface-modified primary paste zinc flake slurry into a solid-liquid separator for solid-liquid separation again to obtain a secondary paste zinc flake, and send the secondary paste zinc flake and dispersant into the In the kneader, high-speed kneading is carried out to obtain pasty zinc flake pigments. By adopting the technical solution of the invention, it is possible to produce paste-like zinc flakes with high metal zinc content and good quality.

Description

technical field [0001] The invention relates to the technical field of production of flake metallic pigments, in particular to a production method and device for pasty zinc flake pigments. Background technique [0002] Zinc flake pigments are mainly used in the preparation of inorganic salt coatings, inorganic zinc-rich coatings, zinc-chromium anti-corrosion coating liquids, chromium-free zinc-aluminum anti-corrosion coating liquids, etc. less, dense coating, and good corrosion resistance, especially the zinc-chromium anti-corrosion coating solution prepared with zinc flake pigment as the main raw material, the salt spray corrosion resistance is obviously better than that of electro-galvanized and hot-dip galvanized, and Pollution is small, it is a high-tech that replaces traditional galvanizing, solves wastewater pollution and improves anti-corrosion performance, and is also a new green coating technology. However, at present, most anti-corrosion coatings are mainly powder...
