At least one of compound, titanium oxide and indium oxide.If plated film target is in addition to above metal simple-substance or oxide
Metal, obtained product weatherability and glossiness is unable to reach check requirements.
Preferably, the functional protection paint is UV hardening paint, anti-aging finish paint, antisepsis finishing paint and phenolic aldehyde protection
At least one of paint.
Preferably, the temperature of the heat cure is 60~90 DEG C, and hardening time is 10~45min.If solidification temperature
Degree is less than 60 DEG C, and the adhesive force and decay resistance of finish paint are unable to reach check requirements；Solidification temperature is higher than 90 DEG C, PMMA base materials
Temperature tolerance problem occurs.
Preferably, the ratio between thickness of the prime coat, the coat of metal and top coat layer is 100:(0.5~1.5):
(20~80).If prime coat thickness is blocked up, it may appear that levelling, the defect such as solidification deficiency, prime coat is excessively thin, it is impossible to cover base material table
Surround and watch the adhesive force deficiency of defect, coated metal and base material in face.
Compared with prior art, the present invention has following beneficial effect：
1st, vacuum plating accessory appearance prepared by the present invention and existing water power chrome-plated part difference in appearance are little, metal-like
By force, but preparation technology is simple, environmental protection and energy saving, continuous production is good, and product qualified rate is high；
2nd, vacuum plating part prepared by the present invention is because overall process is without solution immersion and reagent reacting, product planted agent
Power is small, is easy to weld with automobile lamp lens；
3rd, the vacuum plating part coat of metal and the adhesive force of priming paint that prepared by the present invention are strong, the use increase of protective topcoat
The weatherability of part, scratch resistance and combination property, can meet examination of most of main engine plants to water power chrome-plated material will
Ask；
4th, present invention process flow saves the consumption of precious metal and environmentally friendly cost, with higher price advantage.
