10-15 parts isocyanates, the agent of 1-5 part anti-fingerprints, 1-5 dispersants, 1-2 parts defoamer, 1-2 part levelling agents, wherein anti-fingerprint agent
Include PFPE 50-60 parts, aqueous polyurethane 20-30 parts, epoxy resin 10-15 parts, diatomite 5-8 parts, boiling by weight
Stone 5-8 parts and titanium dioxide 2-5 parts.
The polymer binder includes 50 parts of polyvinyl acetate, 20 parts of polyethylene, 20 parts of polypropylene, poly- by weight
10 parts of vinyl alcohol.
The material of the substrate is carbon steel, aluminium copper coin or plastic plate.
The preparation method of above-mentioned anti-fingerprint stainless steel composite plate, comprises the following steps：
The first step：Stainless steel layer is prepared, by raw material 70-80 parts iron, 15-20 parts chromium, 5-10 parts nickel, the 5-10 of stainless steel layer
Part silicon, 1-3 parts tungsten, 1-3 parts molybdenum, 1-3 parts neodymium, 1-3 parts tin, 1-3 part zirconiums, are put into electric furnace and slightly refine by weight, heating-up temperature
For 1100-1150 DEG C, refined subsequently into Ar-O_2 furnace, heating-up temperature is 1150-1200 DEG C, is casting continuously to form not after finally tapping processing
Rust steel layer；
Second step：Anti-fingerprint agent is prepared, by weight by PFPE 50-60 parts, aqueous polyurethane 20-30 parts, epoxy
Resin 10-15 parts, diatomite 5-8 parts, zeolite 5-8 parts and titanium dioxide 2-5 parts, are stirred by the way of heating water bath
Reaction, wherein bath temperature is 90-95 DEG C, and anti-fingerprint agent is produced after stirring 30min；
3rd step：Prepare varnish, by 40-50 parts acrylic resin, 20-30 parts phenolic resin, 10-15 parts isocyanates,
The agent of 1-5 part anti-fingerprints, 1-5 dispersants, 1-2 parts defoamer and 1-2 part levelling agents are put into reactor, are then stirred,
Whipping temp is 80-90 DEG C, and mixing speed is 100 turns/min, finally gives varnish；
4th step, prepares polymer binder, by 50 parts of polyvinyl acetate, 20 parts of polyethylene, 20 parts of polypropylene, poly- second
10 parts of mixing of enol, then side adds waterside to stir, and stops adding water when viscosity reaches 2000CP, continues to obtain after stirring 30min
Polymer binder；
5th step, stainless steel clad plate is prepared, first by stainless steel clad plate ungrease treatment, and 10min is soaked with passivating solution,
Preheat stainless steel layer and substrate again, then on substrate apply be covered with polymer binder, then carried out with heat-pressing compound machine it is compound,
Wherein combined temp is 100-150 DEG C, finally the varnish coating on stainless steel layer, and natural air drying can obtain anti-finger at room temperature
Line stainless steel clad plate.
Chromium in the stainless steel layer easily generates the fine and close passive state oxide-film of chromium oxide with the oxygen in air, by air
Aqueous vapor and oxygen block outside, protect base material not continue to be influenceed and corroded by oxidation, even if material is in itself by external force or chemistry
Mode destroys surface, chromium oxide also can rapid regeneration into.Nickel can improve reinforcing matrix, improve the intensity of stainless steel, also
