Embodiment 1

[0045] Embodiment 1: Adopted on the surface of the locomotive cast iron engine case.

[0046] In this embodiment, the components and weight percentages of the metal aluminum salt coating agent of the present invention are: edible phosphoric acid 10-12%, aluminum oxide 4.5-5%, zinc oxide 1-2%, phosphatidic acid 1-1.5%, Manganese 1-2%, the balance of water.

[0047] The specific production method steps are as follows:

[0048] 1) First prepare the ingredients according to the ratio, and divide the remaining water into three equal parts;

[0049] 2) Prepare a low-pressure reaction kettle for the container, make the ambient temperature above 30-40°C, and pour the prepared edible phosphoric acid into it;

[0050] 3) Add alumina, then add a portion of water, stir until completely dissolved;

[0051] 4) Add zinc oxide, add a portion of water, and stir until completely dissolved;

[0052] 5) Add manganese, add a portion of water, and stir until completely dissolved;

[0053] 6) A...

Embodiment 2

[0056] Embodiment 2: Applied on the surface of the cast steel body of the locomotive.

[0057] In this embodiment, the components and percentages by weight of the metal aluminum salt coating agent of the present invention are: 18-20% of edible phosphoric acid, 5% of aluminum oxide, 2-4% of zinc oxide, 1-1.5% of phosphatidic acid, 1% of manganese -2%, water balance.

[0058] The specific production method steps are as in Example 1, the difference is that in step 7: use roller coating, brush coating or wiping coating, and keep the ambient temperature at 5°C-20°C to dry naturally, which forms a 25-28 micron film layer on the surface of the cast steel body .

[0059] The locomotive is assembled with this kind of cast steel body, which has good anti-corrosion effect.

Embodiment 3

[0060] Embodiment 3: Applied on the surface of profiles such as Q plates and angle steels.

[0061] In this embodiment, the components and weight percentages of the metal aluminum salt coating agent of the present invention are: edible phosphoric acid 20-25%, aluminum oxide 5-8%, nickel oxide 1-1.8%, zinc oxide 2-3%, phosphorus Esteric acid 1-1.5%, manganese 1-2%, water balance.

[0062] The specific production method steps are as follows:

[0063] 1) First prepare the ingredients according to the ratio, and divide the remaining water into four equal parts;

[0064] 2) Prepare a container so that the ambient temperature reaches above 30-40°C, and pour the prepared edible phosphoric acid into it;

[0065] 3) Add alumina, then add a portion of water, stir until completely dissolved;

[0066] 4) Add nickel oxide, add a portion of water, and stir until completely dissolved;

[0067] 5) Add zinc oxide directly, add a portion of water, and stir until completely dissolved;

Abstract

The invention discloses a metal aluminate covering film agent, a manufacturing method thereof and a metal aluminate covering film, wherein the metal aluminate covering film agent at least comprises the following components in percentage by weight: 10-30% of edible phosphoric acid, 4.5-8% of alumina, 1-1.5% of phosphate ester, at least one of 0-4% of zinc oxide and 0-3% of nickel oxide, 1-2% of manganese and the balance of water. The metal aluminate covering film agent can be film-formed on the surface layer of metal through a high-pressure airless spraying, roller painting, brushing, rubbing or dipping process so as to form a layer of compact protective film. The surface film layer of a conversion film layer formed by the covering film layer agent on the metal surface is compact, firm and wear-resistant, resists the high temperature of 800-1200 DEG C, and has good electrical conductivity, and the surface of the film layer is matched with a resin pole. The inoxidizability and the corrosion resistance of the film layer are equivalent to those of an electrogalvanized, cadmium plated or similar chromium film layer.

Description

technical field [0001] The invention relates to an environmental protection technology, in particular to a metal aluminum salt coating layer which can be applied to the surface of metal manufacturing products and has a unique anti-corrosion effect. Background technique [0002] The traditional pretreatment technology of metal manufacturing products generally adopts phosphating technology to form a film. This technology adopts the theory of thermal kinematics, and the law of corrosion energy and mass conservation of neutral acid formed in nature with mineral phosphoric acid at 60 °C , Mineral phosphoric acid combined with water and oxygen releases energy to dissolve metals with more than two valences and become metal ions. Its metal ions are corrosively applied to the substrate surface of metal products in thermal kinematics; metal ions are adsorbed on the substrate surface to become a phosphating film, and there are acid radicals in the phosphating film layer. The acid radi...
