Embodiment Construction

[0021] 20 kg of rutile titanium dioxide, 50 kg of water glass, 5 kg of boron-containing compound, 15 kg of aluminum hydroxide, 10 kg of talcum powder, 2 kg of rare earth oxide, and 10 kg of water. The mill grinds to 250 mesh; the non-Newtonian fluidization of the paint can be made into a high-temperature metal inorganic marking paint.

[0022] The above-mentioned high-temperature metal-inorganic marking paint prepared by the present invention is sprayed on the surface of an iron plate below 1200 ° C, and kept for 20 minutes, then naturally cooled to room temperature, soaked in water for 24 hours, and compared with similar paints under the same conditions. Focus on, the writing of the coating of the present invention still keeps clear.

Abstract

The invention discloses a high-temperature metal inorganic labeled coating used for a spray printing machine and method for preparing the same. The high-temperature metal inorganic labeled coating comprises the following components by the weight portion: 1-60 of sodium silicate, 1-60 of aluminide, 1-70 of titanium dioxide, 1-50 of talcum powder, 1-10 of rare-earth oxide, and 1-80 of borax or boron-containing compound. The high-temperature metal inorganic labeled coating can be quite well adhered to the metal surface of 300-1200 DEG C and can be provided with an automatic spray painting label or artificial spray painting label.

Description

technical field [0001] The invention relates to a high-temperature metal inorganic marking coating for a jet printer, in particular to an inorganic coating for manually or automatically spraying markings on steel at a temperature of 300°C to 1200°C and a preparation method thereof. Background technique [0002] The high-temperature coatings currently used on steel are mainly used for anti-corrosion and fire-proofing of various steel structures. The use temperature of these coatings is low, and they are applied under normal temperature conditions, and then used after drying. If these coatings are directly used under high-temperature conditions, it is difficult for these coatings to adhere to the high-temperature steel surface due to the huge difference in surface tension between the high-temperature steel surface and the low-temperature steel surface. Due to the above reasons and the huge potential safety hazards of workers' identification under high temperature conditions, ...
