Concrete surface in wall, pond, underground path decorates protection, but is not particularly suited for the environment contacted with benzene kind solvent.
Aqueous colored steel paint product is without the active principles such as formaldehyde, benzene homologues, TDI, soluble heavy metal content strict control
In Europe superscript hereinafter, have many advantages, such as it is environmentally friendly, safe, non-ignitable, not quick-fried, be substitute conventional toxic hazardous solvent type paint Harmless
Upgrading products.Aqueous colored steel paint air drying has preferable oil resistant, water resistance, low toxicity, has to glass reinforced plastic, steel construction, cement
Good adhesive force.With water as solvent, fire risk when can save vast resources, eliminate construction reduces water paint
To atmosphere pollution；Good to material surface adaptability, coating adhesion is strong；Coating tool can wash by water, and it is molten to greatly reduce cleaning
The consumption of agent.
But water paint water resistance in the prior art is insufficient, the protection of matrix surface is inadequate, affects its anti-corrosive properties
Can, and painting defect or the decline of breakdown of coating bring anti-corrosion persistence can not be coped with.
Summary of the invention
Aiming at the above shortcomings existing in the prior art, technical problem to be solved by the invention is to provide a kind of aqueous coloured silks
The method of production of plate paint improves the water resistance and corrosion resistance of aqueous colored steel paint.

For the salt spray test chamber of WV-60, spraying indoor temperature is 35 DEG C, and the concentration of sodium chloride is 50g/L, pH value 6.5.It is specific to survey
Test result is shown in Table 3.
Table 3: antiseptic property test result table
From above-mentioned data it is found that the performance of embodiment 2 is substantially better than embodiment 1, this may be because high-frequency resonance is ground
Machine is passed in cylinder in the form of shock wave by sand cylinder the vibrational energy that inertia vibration generator generates, and high speed is generated in cylinder
Eddy flow energy field, the mill base after sand mill grinding distribution are sheared, are squeezed, are ground, and constantly refinement is decomposed, and it is higher to obtain fineness
Mill base, this is conducive to the raising of aqueous colored steel paint comprehensive performance；Embodiment 3 is surface-treated barium sulfate, enhance its
Compatibility and dispersibility in organic system, to make its surface that there is good hydrophobic oleophilic oil performance；It is right in embodiment 4 and 5
Palta type filler is modified processing, improves wellability of the resin to scale, and scale parallel overlapping arrangement in resin is formed and caused
Close impervious barrier constitutes barrier to corrosive media, to restrained effectively the diffusion of medium.
