Abstract
Relating to a zinc-aluminum paint, the invention provides a formula and a preparation process of a single-component zinc-aluminum paint. According to the formula, the paint is composed of: 10%-30% of a binder, 30%-65% of a zinc sheet, 2%-6% of an aluminum sheet, 0.1%-0.6% of an anti-settling agent, and 15%-25% of a diluent. The paint provided in the invention is not cured at room temperature, and can be used for a long time. The paint does not contain chromium and other harmful metal elements or benzene and other solvents affecting human health, thus having less environmental pollution.
Description
Technical field:
The present invention relates to a kind of zinc-aluminium coating, be specifically related to prescription and the preparation technology thereof of single-component zinc-aluminium coating.
Background technology:
Traditional zinc-rich paint is divided into organic type and inorganic type two large classes.
First inorganic zinc coating, make corrosive medium with zinc powder, silicate is made binding agent, be that CN1182105 has provided a kind of zinc-rich paint such as the Chinese invention patent publication number, be comprised of silicate, silicon sol, zinc powder and water, its binding agent can be a kind of of potassium silicate, water glass, lithium silicate or pure aluminium silicate.
The Chinese invention patent publication number is that CN1254736 has provided a kind of high-module water-based inorganic two-component zinc-rich paint, take potassium silicate as the basis, order adds lithium silicate, precipitated silica, methyltrimethoxy silane and Calucium Silicate powder, makes a kind of coating of two-pack.
The silicate zinc-rich paint is nontoxic, solubilizing agent and fabulous Corrosion Protection is arranged not, but it is not good that its shortcoming is outward appearance, and topmost poor processability is mixed with behind the coating at short notice easily gel solidification, thereby can not adapt to the operation of coating machine continuous and automatic.
Organic type be mostly the bi-component epoxy zinc-rich paint.The bi-component epoxy zinc-rich paint is by first component base-material and second component solidifying agent, and is before construction that both are mixed; After mixed cross-linking and curing reaction occurs namely, it is thick thick that coating becomes gradually, so construction is wanted preferably to require to finish in 15min soon.Therefore, this coating is applicable to brush and spraying, and inapplicable dip-coating as Dacroment applies, this has placed restrictions on this Application of coatings face greatly.
Summary of the invention:
The purpose of this invention is to provide prescription and the preparation technology thereof of single-component zinc-aluminium coating, it can not solidify at normal temperatures, but life-time service does not contain the harmful metal elements such as chromium in the coating, does not contain the solvent that benzene etc. affects HUMAN HEALTH yet, and the environmental pollution impact is less.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its prescription consists of: binding agent 10%～30%, zinc metal sheet 30%～65%, aluminium flake 2%～6%, anti-sedimentation agent 0.1%～0.6%, thinner 15%～25%.
Its preparation technology is:
1, with zinc metal sheet or zinc powder and aluminium flake or an amount of thinner of aluminium oar, nanometer grade silica or wilkinite, then in colloidal mill, grinds evenly and makes zinc, aluminium flake (powder or oar) surface active.
2 with used for epoxy resin pimelinketone and the N-BUTYL ACETATE solvent stirring and dissolving in reactor in 10%: 80% ratio.Reactor has the water-resisting layer heating, is warmed to about 50-80 ℃; Containing Resins, epoxy after the dissolving is 30-60%, and cool to room temperature.
3, add aminoresin and urethane resin.
4, the zinc metal sheet or zinc powder and aluminium flake or the mixtures such as aluminium oar, nanometer grade silica or wilkinite that add the colloidal mill milled.
5, stirred about one hour, coating is uniformly dispersed.
6, in sand mill, grind at last and reach certain fineness, be finished product.
The thickness of described described zinc metal sheet is 0.06～0.2 μ m, median size 5～8 μ m, and also available zinc powder, the fineness of zinc powder is not more than 500 orders (median size is less than 7 μ m); Metallic zinc purity reaches more than 99.9%;
The mean thickness of described aluminium flake is 0.05～0.2 μ m, and median size is 7～8 μ m, also available aluminium oar; Metallic aluminium purity reaches more than 99.9%.
Described binding agent is Resins, epoxy and aminoresin and urethane resin.
Described anti-sedimentation agent can be with nanometer grade silica or wilkinite.
Described thinner can be used diacetone alcohol, pimelinketone, N-BUTYL ACETATE.
The present invention has following beneficial effect: can not solidify at normal temperatures, but life-time service does not contain the harmful metal elements such as chromium in the coating, also do not contain the solvent that benzene etc. affects HUMAN HEALTH, the environmental pollution impact is less.
Embodiment:
This embodiment is by the following technical solutions: its prescription consists of: binding agent 30%, zinc metal sheet 65%, aluminium flake 6%, anti-sedimentation agent 0.6%, thinner 25%.
Its preparation technology is:
