It is respectively provided with adhesive force and the salt water resistance performance of excellence.
The priming paint prepared embodiment further and finish paint carry out decay resistance test, with embodiment 1 preparation
As a example by the finish paint of priming paint and embodiment 4 preparation, the aqueous anticorrosion coat that test priming paint and topcoat composition obtain
Decay resistance, method of testing reference GB/T1771-91, specific as follows:
The tinplate surface that 150mm × 50mm, thickness are 0.3mm is carried out blasting treatment, makes up to St2
Level, basecoat paint embodiment 1 prepared with seven apertures in the human head high atomization spray gun for paint under 0.5MPa air pressure is to the most processed
Tinplate on, spray again after surface drying, altogether spraying 3 times, obtain primer coating, then be prepared by embodiment 4
Finish paint spray 2 times, obtain the sample with aqueous anticorrosion coat after surface drying, testing coating thickness is
100μm；
After sample is put into 90 DEG C of oven drying 4h, the aqueous anticorrosion coat of sample is drawn "×" the deepest
And after base material, put into and salt spray test chamber carries out acid salt mist experiment, acid salt fog experimental technique is with reference to GB/T
1771-91, being replaced with by neutralisation test solution therein with vinegar acid for adjusting pH is the acid test solution after 3,
In testing liquid, salinity is constant.By investigating corrosion degree and the coating of sample after 2000h acidity salt mist experiment
Adhesive force, investigates the Corrosion Protection of anticorrosion coat, and as Corrosion Protection is the best, drawing will at "×"
There is corrosion, cause coating expansion to bubble, and spread under coating, cause drawing generation at "×" bigger
The corrosion of area, is also tested for the adhesive force of anticorrosion coat, attachment before and after acid salt spray test simultaneously
Power test is carried out according to GB9286-98 hundred lattice testing standard.In order to contrast, to U.S.'s Wei Shibai asphalt mixtures modified by epoxy resin
