The present invention adopts rosin as reaction raw materials, with the polymerizable raw material such as maleic anhydride, silane, can form in metal surface stronger diaphragm; Strengthen the decay resistance of metallic matrix.
Description
Technical field
The present invention relates to a kind of metallic surface silanization treating agent and with it technique in metallic surface silanization processing.
Background technology
Phosphatization is processed in coated metal pre-treatment, the industry such as lubricated, antirust and is widely applied. Particularly, in Coating Pretreatment industry, phosphatization processing is one of the most frequently used preprocess method. Phosphatization processing is the process that forms biphosphate ammonium salt diaphragm after metal reacts in acid phosphatase ammonium dihydrogen salting liquid on its surface. Phosphating coat also has good lubricity, insulating properties and corrosion resistance, thereby be widely used in the manufacture field of the products such as automobile, machine-building, Aero-Space and household electrical appliance. Phosphorization treatment process is taking ammonium dihydrogen phosphate (ADP), zinc, manganese, nickel as primary raw material, cause the serious environmental pollution such as heavy metal, phosphorus, nitrite, and in processing procedure, all more or less can produce sediment and pernicious gas, what impact was produced normally carries out, and the waste water COD of discharge and heavy metal will endanger environment if do not carried out environmental protection treatment; In addition, phosphatization processing major part need be carried out under the condition of heating, and energy consumption is larger, complex process, and operation is also inconvenient. Existingly occurred silane surface treatment technology, but silane surface treatment agent is unstable in metal surface film forming, antiseptic property is unstable, poor effect.
Summary of the invention
The object of this invention is to provide a kind of metal surface modification silane finish and preparation method thereof; this solution does not need to heat; not phosphorous, without sediment produce, containing heavy metal, energy-conservation, simple and convenient management, can form stronger diaphragm on duralumin, hard alumin ium alloy surface, anticorrosion ability is good.
Technical scheme of the present invention is as follows:
A kind of metal surface modification silane finish, is characterized in that, made by following component, the weight of each component in every 500 grams of mixed liquors (gram) be:
Sodium dihydrogen phosphate 1-2, ammonium molybdate 1-2, neopelex 1-2, rosin 3-5, trihydroxyethyl isocyanuric ester 1-2, maleic anhydride 5-8, diethylene glycol butyl ether 4-6, isobutanol 5-8, oxalic acid 3-5, urea 1-2, vinyl three ('beta '-methoxy ethyoxyl) silane 7-10, surplus are deionized water.
The preparation method of described metal surface silylation protection treating agent, is characterized in that comprising the following steps:
(1), by rosin heating fusing, to 110-115 DEG C, add diethylene glycol butyl ether, vinyl three ('beta '-methoxy ethyoxyl) silane, stirring reaction 35-50 minute;
(2), be warming up to 145-160 DEG C, add trihydroxyethyl isocyanuric ester, maleic anhydride, stirring reaction 40-50 minute;
(3), continue to be warming up to 190-205 DEG C, add sodium dihydrogen phosphate, ammonium molybdate, neopelex, stirring reaction 40-50 minute;
(4), be cooled to 80-90 DEG C, add other material, stir, insulation reaction 1-2 hour, cooling after, adjust PH be neutrality.
Silane surface treatment agent of the present invention, first metallic matrix can directly be entered in inorganic agent of the present invention and be processed after degreasing, washing, after processing, metal base surface can obtain one deck coating, then can wash or not wash lower one technique-oven dry according to process requirements, after oven dry, can carry out the operations such as powder spray, technological parameter in processing procedure is: operating temperature: 25 DEG C of room temperatures, pure water is washed electrical conductivity < 20 μ s/cm, the processing time: 90-250 second.
Compared to the prior art the present invention, has the following advantages:
(1) the present invention adopts rosin as reaction raw materials, with the polymerizable raw material such as maleic anhydride, silane, can form in metal surface stronger diaphragm; Strengthen the decay resistance of metallic matrix.
(2) in raw material, contain corrosion inhibiter, increase the anticorrosion ability of diaphragm.
(3), the protective film that forms is fine and close evenly, polarized current density is less.
(4) (10 ~ 15 μ m) to protect thickness (< 150nm) to be significantly less than traditional phosphating solutions film.
