Description
Invention field
The present invention relates to a kind of with the method for polymkeric substance to the aluminum alloy substrate coating.More particularly, the present invention relates to a kind of vinyl phosphonate-acrylic copolymer of using, then with the method for polymkeric substance to the substrate coating to the aluminum alloy substrate pre-treatment.
Background of invention
Although aluminium itself can prevent corrosion by forming the native oxide coating, this protectiveness is not thorough.Having in the presence of moisture and the ionogen, aluminium alloy is faster than fine aluminium corrosive.
Therefore, need handle aluminum alloy substrate, to improve its corrosion resistance and the adhesivity good to polymkeric substance with method for pretreating or other chemical process.
In the prior art, by metallic surface " conversion " formed chemical conversion coating for the tight bond coating on aluminium alloy, partial coating is made up of the aluminium of oxidised form.Chemical conversion coating has high corrosion resistance and improved adhesivity to polymkeric substance.Generally, aluminium produces the Plessy's green conversion coating by being contacted with the aqueous solution that contains hexavalent chromium, phosphate anion and fluorion.In recent years, people more and more pay close attention to these technologies to the pollution effect to environment of the chromic salt of waterways discharging and phosphoric acid salt.Because hexavalent chromium has high resolution and strong oxidation characteristics, so, must use expensive waste treatment procedures so that hexavalent chromium is reduced to trivalent chromic ion in order to carry out waste treatment.
People repeatedly attempt producing the chromate-free conversion coating of acceptable aluminium in the prior art.For example, some chromate-free conversion coatings contain zirconium, titanium, hafnium and/or silicon, also are combined with fluorochemical, tensio-active agent and polymkeric substance such as polyacrylic acid sometimes.Although before made very big effort, still do not make us satisfied fully chromate-free conversion coating now or be used to improve the adhesivity of the aluminum alloy substrate of using polymeric coating and the undercoat of erosion resistance.In the Aluminium Alloy Plate polymkeric substance adhesivity and the erosion resistance that are used for making food product containers body and end and beverage container end is important performance.
People repeatedly attempted in the prior art with before the coat substrate with polymers with various organo phosphorous compoundss to its pre-treatment.The term that uses among the application " organo phosphorous compounds " comprises organic phosphoric acid, organic phospho acid, organic phospho acid, the various salt that reach these acid, ester, inclined to one side salt and partial ester.For example, the HOII P 263,668 of 1961.4.14 application discloses a kind of vinyl phosphonate/acrylic copolymer processing steel-sheet method of using before with the coating of Synolac enamel.Although some organophosphorus pretreatment processs can fully carry out, it is very high to use cost.Therefore, still need to provide a kind of method of before coated polymeric, using organo phosphorous compounds pre-treating aluminium alloy substrates of efficient economy at present.
Main purpose of the present invention provides a kind of usefulness organo phosphorous compounds pre-treating aluminium alloy substrates of efficient economy, carries out polymer-coated method then.
In order to reach this main purpose, the method that we provide can remove aluminium and other positively charged ion in the preprocessing solution, has therefore avoided handling the expensive expense of these solution.
To those skilled in the art, can know other purpose of the present invention and advantage by the detailed description part that the following describes book.
