step four, uniformly mixing the negative oxygen ion liquid, the odor-free emulsion, the inorganic modified silicate, the water-resistant agent and the viscosity stabilizer under the stirring state to obtain a stable liquid;
adjusting the viscosity of the stabilizing solution by using deionized water, and filtering to obtain a semi-finished product;
and step six, adding a mildew preventive into the semi-finished product to obtain a finished product.
The scheme has the advantages that:
the inorganic coating prepared by the method has the characteristics of continuously releasing negative oxygen ions, removing coating peculiar smell, purifying air and preventing mildew, can add additional functions to the inorganic coating, and can improve the competitiveness in similar products.
Further, the stirring speed of the stirring state in the first step is 250-350 r/min.
At this stirring speed, the respective materials can be better mixed.

In the above examples, as the dispersant, a BYK194 type dispersant or a Digao Tego D168 type dispersant of Bike, Germany, and as the defoaming agent, a BYK028 type defoaming agent or a FOAMS TAR A10 type defoaming agent of Kenin, Germany, were used. The mildew preventive is made of mildew preventive of Trojan or Sol. The mildew preventive without formaldehyde replaces the prior preservative containing formaldehyde, so that the coating is more healthy and environment-friendly and is suitable for living.
When the dispersant of examples 1 to 3 was a BYK194 type dispersant and the defoaming agent was a BYK028 type defoaming agent, examples 1 to 3 correspond to the inorganic coating materials of examples3) All are 2000-3000 pieces/cm3And the prepared inorganic coating is odorless. The inorganic coating prepared by the existing method and the corresponding material has the negative oxygen ion air concentration (per cm)3) Only 60-150 pieces, and the prepared inorganic paint has emulsion smell. The data show that the coating of the scheme not only contains the characteristics of good adhesive force, good construction performance, washing resistance, chemical resistance meeting the standard and the like of the existing inorganic coating, but also has lower content of free formaldehyde. The content of the negative oxygen ions is obviously higher than that of the conventional inorganic coating.
Example 4
The difference from the above examples is that the natural latex liquid was added to the mildewcide in this example in an amount of 50%. After the paint is coated, a layer of film can be quickly formed on the surface of the paint for protection, so that the function of mildew prevention and protection is achieved, and physical covering protection is formed on the surface of the paint.
The invention uses the odorless emulsion, the emulsion is self-environment-friendly, the lowest film forming temperature is achieved, the film forming auxiliary agent is not needed, and compared with the common film forming auxiliary agent, the dodecanol ester is an organic volatile matter, the invention does not use the film forming auxiliary agent, reduces the pollution to the air, and is more environment-friendly.
In examples 1 to 4, the odor-free emulsion is obtained by modifying a styrene-acrylic emulsion with an organosilicon monomer, which is referred to as a silicone-styrene-acrylic emulsion for short, and has good oxidation resistance and decomposition resistance. The organic silicon has large molecular volume, small surface tension, low cohesive energy density, good anti-contamination property, air permeability and hydrophobicity. The emulsifier used in the odorless emulsion has good alkali resistance, large particle size, wide distribution and good compatibility with silicate (the silicate is strong alkali).
In examples 1 to 4, the silicate used was modified potassium silicate, and specifically, potassium lithium silicate was used. The water-soluble silicate is commonly called water glass, and includes lithium, sodium, potassium, ammonium water glass and the like. The potassium water glass has better caking property and film forming property than sodium water glass, and has lower price than lithium water glass and ammonium water glass, so the commonly used potassium water glass is used as a film forming substance of the inorganic coating. The conventional potash water glass forms a coating film with poor water resistance, and the improved potassium silicate is used, namely lithium potassium silicate.
In examples 1 to 4, the viscosity stabilizer was a quaternary ammonium salt product, and this positively charged macromolecule covered the negatively charged chain end of the silicate chain, which acted as a protecting group, and sterically blocked the reaction of the Si — O bond, resulting in good stability of the product. Without the addition of such viscosity stabilizers, the silicate reacts with other components of the system over time, which can lead to gelling and hardening.
In the embodiments 1-4, the core material of the anion paint additive is anion, and is formed by processing, refining, compounding and activating a plurality of gem jade spar by a plurality of high-tech means according to the prior art; the production process adopts various advanced process technologies such as sol centrifugal crushing ion exchange doping and the like, so that the negative ion has the functions of purifying air water, resisting electromagnetic radiation and the like, and has the effects of resisting bacteria, inhibiting bacteria, protecting health and the like.
The positive and negative charge centers of each unit body of the negative ion coating additive can not coincide, so that the positive and negative electrodes are formed at the two ends, and a permanent charged body permanent electrode is formed, wherein the positive and negative charges have no symmetric center, namely, dipole moment. When the external temperature or the external pressure changes slightly, the ion distance and the bond angle change to induce dipole moment, so that part of the free charge layer bound on the surface of the unit body is released, the unit body is in an electrified state or forms current in a closed loop, and an electric field and micro-current are formed around the free charge layer.
In examples 1 to 4, the water-resistant agent is polyether-modified organosilicon, and can react with the emulsion and potassium silicate to form a firm chemical bond, thereby greatly improving the wrapping capability of the emulsion on pigments and fillers and improving the physical mechanical strength of a paint film, and further remarkably improving the water resistance, scratch resistance, weather resistance, scrub resistance, wear resistance and the like of the coating. Reacts with the substrate with inorganic surface to form firm SI-o-Si bond, thereby greatly improving the adhesion of the coating to the substrate.
