Abstract
A ceramic powder paint is prepared from inorganic filler of natural ore (40-60 wt.%), thicking agent (1-5), solidifying agent (3-10), adhesive (20-40), and complexing agent (1-5). Said adhesive contains sodium silicate, ethyl acetate, Ba-Al-Pb catalyst, urea and formaldehyde. Its advantages are no damage to people and animal, no poison and no environmental pollution.
Description
The invention relates to a water-based paint, in particular to a solid ceramic powder paint taking water as a solvent.
The existing water paint also contains organic solvent when in use, and the organic solvent causes pollution to operators and the surrounding environment. Because organic solvents are used, the formed coating is generally liquid, is inconvenient to package, store and transport, and has poor stability.
The invention aims to provide a ceramic powder coating which can be used only by being mixed with water without organic solvent.
The ceramic powder coating is prepared from natural mineral inorganic filler, a thickening agent, a curing agent, a binder and a complexing agent, and is characterized in that: the adhesive consists of an acetate sodium silicate graft and a sodium silicate urea graft, wherein the acetate sodium silicate graft and the sodium silicate urea graft are prepared by stirring 20-25 parts of sodium silicate, 40-50 parts of ethyl acetate, 5-10 parts of barium-aluminum-lead catalyst, 15-20 parts of urea and 5-8 parts of formaldehyde at the temperature of 85-95 ℃ for 4-6 hours, then cooling to about 60 ℃ for 4 hours to obtain the dried acetate sodium silicate and sodium silicate urea graft, and crushing the dried acetate sodium silicate and sodium silicate urea graft.

The paint is coated on the surfaces of various rusted steel and iron, and has excellent functions of rust prevention, corrosion prevention and water prevention.
The ceramic powder paint product is mainly made of natural inorganic material, has no harm to human body and animal, and is non-toxic, tasteless and nuisanceless. The ceramic powder coating product is a solid powder. When in construction, the paint can be used by only using tap water to adjust the viscosity to a proper value.

The coating film has high mechanical strength, stable chemical performance, high elasticity, high tracing performance and high flexibility, and completely solves all quality and service life problems caused by the aging of the material. Has special functions and high efficiency of generating the excess value. The reaction mechanism of the ceramic powder coating is carried out in a curing and complexing mode, firstly, a phosphate curing agent is condensed to silicate for curing reaction, and meanwhile, a complexing agent is complexed to alkali metal for forming a complex. In addition, the condensed phosphate not only has the performance of curing silicate, but also has the function of phosphating the metal surface under the combined action of the complexing agent to form a stable protective layer and has excellent adhesive force.
An example of the reaction is as follows:
the corrosion prevention mechanism is as follows:
3Me(H2PO4)2H2O3MeHPO4＋3H3PO4
me is divalent metal Ca, Zn, Mg, etc. And simultaneously, dissolving steel to generate iron hydrogen phosphate:
the above results show that the phosphate conversion layer is integrated with the metal to change the metal surface into an insulation isolation layer of a poor conductor, which can prevent the corrosion and spread of the metal.
