Metal surface silicane treating agent containing tetraisopropyl titanate and preparing method thereof

Abstract

The invention discloses a metal surface silicane treating agent containing tetraisopropyl titanate and a preparing method thereof. The metal surface silicane treating agent containing the tetraisopropyl titanate is prepared form following compositions of, by weight (g) in every 500g of mixed liquor, 1-2g of tetraisopropyl titanate, 1-2g of amine benzoate, 3-5g of rosin, 1-2g of trihydroxyethyl isocyanurate, 10-12g of maleic anhydride, 4-6g of diethylene glycol monobutyl ether, 5-8g of propylene glycol, 2-3g of formic acid, 10-12g of N-(beta-aminoethyl)-gamma- aminopropyl trimethyl (triethyl) oxygroup silicane and the balance deionized water. The metal surface silicane treating agent containing the tetraisopropyl titanate and the preparing method use the rosin as reacting raw materials to polymerize with raw materials of the maleic anhydride, the silicane and the like, and accordingly strong protective film can be formed on the surface of metal, and decay resistance of a metal matrix is strengthened.

Description

technical field [0001] The invention relates to a silanization treatment agent on the metal surface and a process for silanization treatment on the metal surface. Background technique [0002] Phosphating treatment has been widely used in metal coating pretreatment, lubrication, antirust and other industries. Especially in the coating pretreatment industry, phosphating treatment is one of the most commonly used pretreatment methods. Phosphating treatment is a process in which a protective film of ammonium dihydrogen phosphate is formed on the surface of a metal after reacting in an acidic ammonium dihydrogen phosphate solution. Phosphate film also has good lubricity, insulation and corrosion resistance, so it is widely used in the manufacturing fields of automobiles, machinery manufacturing, aerospace and household appliances. The phosphating treatment process uses ammonium dihydrogen phosphate, zinc, manganese, and nickel as the main raw materials, causing serious environ...

AI Technical Summary

Problems solved by technology

The phosphating treatment process uses ammonium dihydrogen phosphate, zinc, manganese, and nickel as the main raw materials, causing serious environmental pollution such as heavy metals, phosphorus, and nitrite, and will more or less produce sediment and harmful gases during the treatment process. It affects the normal production, and the discharged wastewater COD and heavy metals will endanger the environment if they are not treated in an environmentally friendly manner; in addition, most of the phosphating treatment needs to be carried out under heating conditions, which consumes a lot of energy, the process is complicated, and the operation is inconvenient

Silane surface treatment technology has appeared, but the film formation of silane surface treatment agent on the metal surface is unstable, the anti-corrosion performance is unstable, and the effect is not good
