Description
Technical field
The present invention relates to a kind of Dyclo paint, belong to anti-corrosion of metal field, and in particular to a kind of excellent in mechanical performance
Chromium-free Dyclo paint and preparation method thereof.
Background technology
Steel corrosion can all directly result in substantial amounts of accident or form accident potential every year, cause huge economic loss,
Have a strong impact on national economic development and safety.How to provide lasting corrosion resistance power also just becomes the focus of research.Reach
Crow coating is a kind of metal anti-corrosive paint constituted with flake zinc powder, aluminium powder chromic anhydride and organic reducing agent, strong resistance to by it
Corrosive nature, high temperature resistant, there is high osmosis, be used widely rapidly, however, due to containing in the dacroment process liquid
There are about 2% high carcinogenic and supervirulent Cr6+.Therefore at present Dyclo paint exist not environmentally, wearability is bad etc. lacks
Point.
Chromate in Dacromet/steel mainly plays bonding agent and passivator, and the substitute materials of selection chromate are
The problem of Non-chromium Zn-al Coating urgent need to resolve.《The preparation and corrosion resistance mechanism research of novel anticorrosion coating chromium-free Dyclo》Master
In academic dissertation, Wang Quanquan uses polyurethane modified epoxy resin for binding agent, and polyamide is curing agent, coordinates flakey
Aluminum zinc powder is prepared for a kind of chromium-free Dyclo paint, but haves the shortcomings that wearability, intensity are bad.
The content of the invention
It is an object of the invention to provide a kind of chromium-free Dyclo paint and preparation method thereof, overcome Dyclo paint current
The shortcoming that wearability is bad, intensity is not high of presence, the technical solution adopted by the present invention is as follows：

10-15, vinyl triamine 10-15, diamond dust 1-2, zinc powder 20-30, aluminium powder 20-30, Silane coupling agent KH550 40-50, second
Alcohol 5-10, acetone 50-70, dimethyl silicone polymer 0.3-0.6；
The zinc powder and aluminium powder are flake powder.
2. described in the chromium-free Dyclo paint of a kind of excellent in mechanical performance and preparation method thereof, it is characterised in that including
Following operating procedure：
A. ultrasonic disperse is carried out 1-2 hours to schmigel with ethanol solution, filtration drying；
B. schmigel obtained by step a and carbon fiber, carborundum, boron nitride, polytetrafluoroethylene powder and diamond dust are ground in mortar
Mill makes it be transferred to after being sufficiently mixed in crucible, is placed into body of heater and is evacuated to 10-2Below Pa, and stove body temperature is risen to
250-350 DEG C, constant temperature is down to room temperature after 20-50 minutes, obtains mixture；
C. mixture obtained by step b is put into homogenizer, sprayed after Silane coupling agent KH550, stirring 10-30min,
1-3h is dried at 100-150 DEG C.
D. acetone and dimethyl silicone polymer are added into mixture obtained by step c, mechanical agitation is uniform, and base-material is made；
E. epoxy resin E42, vinyl triamine, zinc powder and aluminium powder are added in base-material obtained by step d, stir 1~3h, i.e.,
Obtain chromium-free Dyclo masking liquid.
3. described in the chromium-free Dyclo paint of a kind of excellent in mechanical performance and preparation method thereof, it is characterised in that heating
Stove is Medium Frequency Induction Heating Furnace or resistance-heated furnace.
The beneficial effects of the invention are as follows：Use epoxy resin E42 for binding agent, vinyl triamine is curing agent, with molten
Agent is volatilized, and curing cross-linking reaction occurs for epoxy resin E42 and vinyl triamine curing agent, may eventually form fine and close, homogeneous, continuous
Film layer.Meanwhile, schmigel and carborundum are introduced, and schmigel and carborundum are handled with polytetrafluoroethylene powder, not only make it more
Good is dispersed in coating, and considerably increases the intensity and anti-wear performance of coating, shows good mobility and attachment
Property, the coating densification of formation is smooth, solves that Dacroment masking liquid intensity is smaller, the shortcoming that wearability is bad, great market competition
Power；Cooperation with the addition of carbon fiber, boron nitride, improve the mechanical property and toughness of coating.
