The invention relates to a coating for preventing intermetallic bonding, in particular to a water-based high-temperature-resistant titanium-steel anti-bonding coating and its use in the preparation process of titanium ingot. The water-based high-temperature-resistant titanium-steel anti-bonding coating of the invention includes the following components in parts by weight: 50-150 parts of water-based film-forming agent, 0-50 parts of Zn powder, 400-450 parts of AlOpowder, and 250-350 parts of talcum powder. The coating of the invention can avoid the bonding reaction with a roller or a winch of the steel equipment in the rolling or perforation process of a titanium tube at 900&#xb0; C., so as to improve the yield and the production efficiency of titanium material processing. Moreover, the process is simple and easy to operate, the coating is environment-friendly and pollution-free, and easy to prepare.

Water-based high-temperature-resistant titanium-steel anti-bonding coating and use thereof

A metal protective coating is provided, which is obtained by mixing homogeneously a raw mixture, which contains water soluble silicate, promoter, silane coupling agent, silicon oxide packing, water soluble film formation resin, and water; wherein, the promoter is at least one selected from the group consisting of methyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, carboxymethyl-hydroxyethyl cellulose, and their soluble salts; the silane coupling agent contains a first silane derivative shown in formula (1), wherein, R, R, and Rare methoxyl or ethyoxyl respectively, and n is an integer with the range of 1-4. A hot-dip Zn metallic material and a hot-dip Al&#x2014;Zn alloy metallic material are further provided. The protective film formed by the metal protective coating as provided has outstanding corrosion resistance, water resistance, thermal resistance, and fingerprint resistance properties. 

Metal protection coating, hot-dip Zn metallic material and hot-dip Al&#x2014;Zn metallic material using the same

A coating composition is provided, the starting materials of which comprise nano SiO, film-forming substance, film-forming aid, accelerator, acid, and water. The composition has pH of 3-9. A passivated zinc-plated material is also provided. The zinc-plated material comprises zinc-plated substrate and passivated coat adhered to the surface of the zinc-plated substrate, wherein the passivated coat is formed by curing the coating composition. The coating composition can impart to the zinc-plated material excellent corrosion resistance, water resistance, high temperature resistance, surface conductivity, and adhesion to the zinc-plated substrate. Additionally, the coating composition contains no Cr, and satisfies the requirement of EU RoHS Directive.

Preparation method of hot dip galvanized sheet anti-corrosive treatment agent of environmental protective

The present invention provides a passivant for hot-dip Al&#x2014;Zn-coated sheet of which the raw materials include: 2&#x2dc;6 parts by weight of water soluble molybdate, 4&#x2dc;12 parts by weight of water soluble manganese salt, 50&#x2dc;100 parts by weight of basic silica sol and 50&#x2dc;100 parts by weight of water soluble organic resin. The present invention also provides a method to prepare the passivant for hot-dip Al&#x2014;Zn-coated sheet including the following steps: adding and dissolving water soluble molybdate and water soluble manganese salt into deionized water; adding basic silica sol into the solution and mixing well; adding water soluble organic resin into the solution and mixing well; regulating the pH value of the solution to 5&#x2dc;8 by using phosphoric acid. The present invention also provides a hot-dip Al&#x2014;Zn-coated sheet treated with the present passivant and a method to passivate hot-dip Al&#x2014;Zn-coated sheet.
