Crosslinking agent for zirconium salt coating
Zirconium salt coating crosslinking agent can crosslinking acrylic acid resin containing carboxylic acid, and zirconium salt crosslinking agent has good film performance.
The zirconium salt crosslinking agent used in coatings can be used in water-based coatings, which has good heat resistance, resistance to friction and water resistance. The crosslinking reaction of ammonium carbonate crosslinking agent in ammonia neutralization of acrylic resin.
Zirconium is a chemical element. Its chemical symbol is Zr. Its atomic number is 40, which is a high melting point metal, which is light grey. Density 6.49 g/m3. The melting point of 1852 + / - 2.001 ℃, boiling point 1852 ℃. Valence + 2, + 3 and + 4. The first ionization energy is 6.84 electron volts. The surface of zirconium is easy to form an oxide film and has a luster, so the appearance is similar to steel. Corrosion resistant, soluble in hydrofluoric acid and wang water, high temperature, can react with non-metallic elements and many metal elements, generate solid solution compounds.
Natural silicate containing zirconium ZrSiO4 called Zircon (Zircon) or hyacinth stone (hyacinth) widely distributed in nature, with everything from orange to red beautiful color, since the ancient times is considered a gem, Zircon is said to have a word from the Arabic Zarq ū n, cinnabar, say from Persian Zargun, is golden, hyacinth comes from the Greek word "lily", in the Indian Ocean island of Sri Lanka is rich in Zircon. Gems containing zirconium are known in ancient times as zircons.
1789 germans M.H.K laproth study of zircon, it fused with sodium hydroxide, hydrochloric acid to dissolve the cooling, adding potassium carbonate in aqueous solution, precipitation, filtration and cleaning sediment, sediment and then cook with sulfuric acid, and then filter the silicon oxide, check in the filtrate of calcium, magnesium, aluminum oxide, has not been found, after adding potassium carbonate precipitation in aqueous solution, the sediment is not soluble in alkali as alumina, also don't like magnesium oxide and acid, Klaproth think the sediment and previously known oxides is different, is made up of Zirkonerde (zircon, German), soon, French chemist DE Morueau and Vauquelin both confirmed M.H.K laproth analysis is correct, the element Latin name Zirconium, symbol that Zr, Zirconium translated into Chinese.

In 1808, the British H.D avy zirconium compounds using current decomposition, without success, 1824 Swedish J.J.B erzelius first with K2ZrF6 potassium restored with metal zirconium, but is not pure, reactive as: K2ZrF6 + 4 k = Zr + 6 kf, the reaction can also be used Na as reductant, until 1914, when a Dutch metal incandescent lamp factory two researchers Lely and Ham bruger with anhydrous zirconium tetrachloride and excess sodium metal with sheng into the ball out, using the current heated to 500 ℃, the pure metal zirconium.
The fully pure zirconium was first made by the Dutch chemist Anton Eduard van Arkel and Jan Hendrik DE Boer in 1925 by the decomposition of zirconium iodide (ZrI4). The metal is now being produced in large quantities by magnesium, a zirconium tetrachloride.
Zirconium readily absorbs hydrogen, nitrogen and oxygen; Zirconium's affinity for oxygen is very strong, 1000 ° C zirconium oxygen dissolved in can make its volume increased significantly. The surface of zirconium is easy to form an oxide film and has a luster, so the appearance is similar to steel. Corrosion resistant, but soluble in hydrofluoric acid and wang shui. In high temperature, it can react with non-metallic elements and many metal elements to form solid solution. The plasticity of zirconium is good, easy to be processed into plates, silk and so on. Zirconium can absorb oxygen, hydrogen, nitrogen and other gases during heating, and can be used as hydrogen storage material. The corrosion resistance of zirconium is better than titanium, close to niobium and tantalum. Zirconium and hafnium are two metals that are chemically similar to each other and contain radioactive substances.
Development of thick film type fast crosslinked epoxy coating has excellent mechanical properties and corrosion resistance properties of various performance at or above the SY/T 0315-2005 about the requirement of the coating performance, can meet the technical requirements of pipeline repairing. A brush or spray coating can reach 1000 mu m, which can reach the design film thickness at one time, and the coating can be crosslinked quickly in 3.5 hours, which improves the construction efficiency. The construction of coating (application period) is studied to guide the site construction.
