Abstract
The invention discloses a surface silanization protection treatment agent for corrosion inhibiting and resisting metal. The surface silanization protection treatment agent is prepared from the following ingredients in weight (gram) in every 500g of mixture liquid: 1-2g of benzoic acid amide, 1-2g of triethanolamine, 3-5g of methyl cellulose, 8-10g of rosin, 0.5-1.2g of trihydroxyethyl isocyanurate, 10-12g of maleic anhydride, 4-6g of diethylene glycol butyl ether, 5-8g of isopropanol, 0.5-1g of ammonium dihydrogen phosphate, 1-2g of urea, 5-8g of N-2-(aminoethyl)-3-aminopropyl trimethoxysilane and the balance of deionized water. According to the surface silanization protection treatment agent, rosin serving as a reaction raw material is polymerized with raw materials, such as maleic anhydride and silane, and then, a strong protecting film can be formed on the surface of metal; and the corrosion resistance of metallic matrixes is enhanced.
Description
Technical field
The present invention relates to a kind of at metallic surface silanization treating agent and with its technique of processing at metallic surface silanization.
Background technology
Bonderizing is widely applied in coated metal pre-treatment, the industry such as lubricated, antirust.Particularly in the Coating Pretreatment industry, bonderizing is one of the most frequently used pretreatment process.Bonderizing is to form the process of biphosphate ammonium salt protective membrane after metal reacts in acid phosphatase ammonium dihydrogen salts solution on its surface.Phosphatize phosphate coat also has good oilness, insulativity and solidity to corrosion, thereby be widely used in the manufacturing field of the products such as automobile, machinofacture, aerospace and household electrical appliance.Phosphorization treatment process is take primary ammonium phosphate, zinc, manganese, nickel as main raw material, cause the serious environmental pollution such as heavy metal, phosphorus, nitrite, and all more or less can produce sediment and obnoxious flavour in treating processes, what impact was produced normally carries out, and the waste water COD of discharging and heavy metal will endanger environment as not carrying out environmental protection treatment; In addition, the most of need of bonderizing carried out under the condition of heating, and energy consumption is larger, complex process, and operation is also inconvenient.Existing the silane surface treatment technology occurred, but the silane surface treatment agent is unstable in the metallic surface film forming, antiseptic property is unstable, poor effect.
Summary of the invention
The purpose of this invention is to provide a kind of inhibition protection against corrosion metal surface silylation protection treating agent and preparation method thereof; this solution does not need to heat; not phosphorous, produce, do not contain heavy metal, energy-conservation, simple and convenient management without sediment; can form stronger protective membrane on the duralumin surface, anticorrosion ability is good.
