Abstract
Include acetate, benzoic acid, phosphoric acid, sodium benzoate, Igepon T, AEO, POCA, organotin, potassium stearate, reactive diluent, deionized water by mass percentage without nickel hole sealing agent, the hole sealing agent the invention discloses a kind of anodic oxidation.The present invention can carry out Seal treatment to anode oxide film well, and sealing of hole speed is fast, and environmentally safe；Pastiness greening, any surface finish do not clean product after sealing of hole, not nickeliferous, fluorine, meet national environmental protection and the demand of European Union ROHS instructions.In addition, with the addition of the auxiliary agents such as Igepon T, AEO, POCA, organotin, potassium stearate and reactive diluent, sealing of hole effect efficiency is further improved, and causes the more firm stable, corrosion-resistant of the material surface after sealing of hole.
Description
Technical field
The present invention relates to the hole sealing technology field of anode oxide film, more particularly to a kind of anodic oxidation is without nickel hole sealing agent.
Background technology
At present, the external use for hole sealing agent is mainly nickel salt hole sealing agent.Wherein with the high temperature nickel acetate sealing of hole of Japan
Based on agent and American-European normal temperature nickel acetate hole sealing agent.The sealing quality of high temperature nickel acetate hole sealing agent is compared with normal temperature nickel acetate hole sealing agent
Good, application is more extensive, its principle be nickel ion under certain pH, with collective effect, hydrolysis and the hydrolysis such as water, surfactant
Product, which is suitably assembled into aluminium surface, to be aoxidized membrane pores and realizes sealing of hole；PH buffer plays stablizing solution pH value and control nickel ion
The effect of hydrolysis degree；Surfactant etc., complex is formed with nickel ion, controls the concentration and amount of hydrolysis of simple nickel ion,
Meanwhile appropriate scattered, wetting effect is produced in pore-sealing liquid, nickel ion hydrolysate is kept appropriate aggregation, so as to protect
Card occurs without pollen, dyeing dispersive effects is minimized, while has faster sealing of hole speed again.The ring caused by nickel salt sealing of hole
Border problem, foreign countries are promoted to develop novel non-nickel hole sealing agent.The country, that started late in terms of aluminium material surface processing are autonomous
Hole sealing agent is less.Mainly by import, and domestic aluminium material surface processing market is big, hole sealing agent extensive market.
Application number 2016105833218 discloses a kind of aluminium material surface hole sealing agent, by nickel acetate, Acetic acid-sodium acetate, and auxiliary agent,
The components such as surfactant, which are mixed with, to be formed.The hole sealing agent has used nickel, and nickel is most common sensitization metal, there are about 20%
The people of left and right is higher than male patient to nickel ion allergy, the number of female patient, and when with human contact, nickel ion can lead to
Cross pore and sebaceous glands penetrates into vivo, health is damaged.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of anodic oxidation without nickel hole sealing agent, solve hole sealing agent envelope
Hole efficiency is low, the defects of easily causing environmental pollution.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of anodic oxidation includes by mass percentage without nickel hole sealing agent, the hole sealing agent
Further improvement is that the hole sealing agent includes by mass percentage
Further improvement is that the acetate is selected from ammonium acetate, cobalt acetate, sodium acetate, potassium acetate, calcium acetate, acetic acid
One or more in magnesium.
Further improvement is that the one kind or more of the organotin in stannous methide, tetraphenyltin, dioctyl tin
Kind.
Further improvement is that the one kind or more of the reactive diluent in HK-66, HELOXY505, HELOXY48
Kind.
The beneficial effects of the invention are as follows：The present invention can carry out Seal treatment to anode oxide film well, and sealing of hole speed is fast,
It is and environmentally safe；Pastiness greening, any surface finish do not clean product after sealing of hole, not nickeliferous, fluorine, meet national environmental protection and European Union
The demand of ROHS instructions.In addition, it with the addition of Igepon T, AEO, POCA, organotin, potassium stearate and activity
The auxiliary agents such as diluent, sealing of hole effect efficiency is further improved, and cause material surface more firm stable, the corrosion resistant after sealing of hole
Erosion.
