Description
Technical field
The present invention relates to the preparation fields of sealer, specifically further relate to a kind of metal surface high rigidity scratch, resistance and fingerprint resistance
Sealer and preparation method thereof and application method.
Background technique
Hot-dip metal plated material, including hot-dip galvanized metal material and hot-dip aluminizing zinc metal material, corrode, all in order to prevent
One layer of antirust sealer can be applied to form protecting film on the surface of hot-dip metal plated material.Magnesium alloy has good light weight,
Machinability, corrosion resistance, damping property, dimensionally stable and impact resistance, it is much high-quality in other materials.These characteristics make magnesium alloy
There are application, such as a traffic and transport field in wide range of areas, electronics industry, medical field, war industry etc., this trend only increases
Do not subtract.Especially in 3C Product (computer Computer, consumer electronics product Consumer Electronic
Product, communication class Communication), high-speed rail, automobile, bicycle, aerospace, building decoration, handheld tool, medical treatment
The fields such as rehabilitation appliances application prospect is good, potentiality are big, has become one of the developing direction of the following new material.The property of magnesium metal

It is the most simple and minimum cost processing method of technique at processing.Traditional Conversion Coating Technology mainly uses Cr VI
Ion forms one layer of fine and close protective film in Mg alloy surface, substrate can be effectively protected and be not corroded, and technique low in cost
Simply it is widely used.But hexavalent chromium has toxicity and strong carcinogenicity, seriously endangers ecological environment and human health.Cause
This environmentally protective magnesium alloy chemical process technology is main research direction.
In recent years, magnesium alloy chromium-free phosphatization epithelium technology makes some progress in application study, such as: magnesium alloy calcium
Vanadium system epithelium, calcium manganese vanadium system epithelium, phytic acid processing, the processing of zirconium epithelium etc..Wherein calcium vanadium system, calcium manganese vanadium system's epithelium have film forming
Stablize, Corrosion Protection is good, conducts electricity very well and at low cost etc. is widely used in the surface treatment of magnesium alloy.This kind of epithelium
The insoluble type precipitating that layer is mainly made of the calcium manganese compound of calcium phosphate, manganese phosphate and other phosphoric acid formula salt forms, but by
Lower in this kind of skin membrane hardness, during product handling process or post-processing, skin membrane is easy to be scratched by adjacent product broken
Badly to expose magnesium alloy metal substrate, causes product corrosion to scrap, greatly reduce the qualification rate of product, it is unnecessary to cause
Loss, seriously affected the application and development of magnesium alloy.

Performance test
To sealer application method prepared by embodiment 1-10: will be by epithelium treated metal product overflow washing
Afterwards, it is put into immersion treatment in the sealer, treatment temperature is 45 DEG C, is handled the time 60 seconds, is put into 130 DEG C of bakings after overflow washing
It is toasted 15 minutes in case.
1, the hardness measuring method are as follows: tested according to GB/T4340.1-1999；
2, the resistance and fingerprint resistance test method are as follows: extruded with finger and handle plate surface, to visually observe fingerprint in processing board
Trace；10 grades indicate that effect is optimal entirely without trace；1 grade of obvious remaining trace, effect is worst, is divided into 10 grades；Use reality
Resistance and fingerprint resistance effect after applying the sealer of example 1 is as shown in Fig. 2；
3, salt spray test method are as follows: it is put into test box after cleaning product, parameter is set, the chlorine for the use of solution being 5wt%
Change sodium solution is sprayed the amount that settling amount is 5mL/h and carries out sustained firing 24 hours to it at 1MPa pressure, 47 DEG C, and test is completed
Product is taken out afterwards, test product flushing is rinsed with distilled water after five minutes with circulating water, be dried, drying time is 30 points
Clock, drying temperature are 80 DEG C, and judgment criteria is that no gas rises, oxidation, burn into such as get rusty at the abnormal phenomenon, division is excellent, in, it is three kinds poor
Grade；It is as shown in Fig. 4 using the resistance and fingerprint resistance effect after the sealer of embodiment 1；
4, heat-resisting quantity, hydrophobicity, anti-finger printing: resistance to after being handled using sealer prepared by embodiment 1 magnesium alloy
It is high temperatures: to the discoloration for placing 24 hours unclosed and closed magnesium alloys of observation in 300 DEG C of high temperature, such as attached drawing 5 and attached
Shown in Fig. 6；Hydrophobicity: it is as shown in the picture to observe hydrophobic situation；Test result is as shown in Fig. 3.
