Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an inorganic fireproof relief coating as well as a preparation method and application thereof.
Background
In recent years, inorganic coatings are favored and pursued by people with excellent performance, compared with organic coatings, most inorganic coating products take water as a dispersion medium, and raw materials are often directly taken from the nature, so that the sources are very rich, the pollution to the environment in the production and use processes is small, and no adverse effect on the environment and the health is caused.
The inorganic coating is strong alkaline, and is more suitable for application on basic layers of cement, sand lime and the like which are also alkaline, silicate colloid permeates into the base materials, can generate chemical reaction with lime in the base materials to generate calcium silicate crystals, and can be integrated with the base layers, so that the inorganic coating has the advantage of particularly good adhesive force, has waterproofness and high air permeability, enables water in the stone building to be freely evaporated outwards, has the filtering effect of alkaline substances, has excellent mildew resistance after being cured, does not breed mildew, and can prevent the defects of bubbling, thermal explosion, scale peeling and the like of the coating. Therefore, the aging resistance and certain physical and chemical properties of the inorganic coating are difficult to achieve by most of organic coatings with the same production cost, so that the inorganic coating has better technical and economic properties.
The relief paint belongs to the category of thick multi-layer paint and has better protection effect on buildings. Compared with the conventional inorganic coating, the plane effect is richer, the inorganic fireproof relief coating film can be made into patterns such as concave-convex patterns, ripples, orange peels or circles, the color of the inorganic fireproof relief coating film can be a single color, double colors or a combination of multiple colors, or the inorganic fireproof relief coating film can be matched with different cover surfaces, the gloss can be dull, semi-gloss, bright, pearly and the like, the inorganic fireproof relief coating film has three-dimensional effect, the building can be endowed with luxury and solemn feelings, and the inorganic fireproof relief coating film has better protection effect on walls.
The relief paint has spots with different sizes, so that the stereoscopic impression and the visual aesthetic feeling can meet the increasing requirements of people on the decoration of the paint. At present, a small amount of relief paint in the market mostly takes pure acrylic emulsion and styrene-acrylic emulsion as main film forming substances. CN103709844A discloses a flash relief coating, which comprises the following components in percentage by weight: emulsion: 13-15% of cellulose ether solution: 13-15% of a dispersant: 0.5-0.6%, wetting agent: 0.05-0.15%, defoaming agent: 0.15 to 0.25%, propylene glycol: 0.8-1.2%, triple superphosphate: 40-41% of quartz sand: 25-27%, lignocellulose: 0.25 to 0.35%, film formation: 0.8-1.2%, bactericide: 0.15-0.25% and pearl powder: 1.5-2.5%; the paint has excellent water resistance and alkali resistance, good adhesive force, artistic sense of embossment, golden and brilliant color, gorgeous appearance and remarkable anti-permeability performance, and can remarkably improve the waterproof performance of a wall body; however, the coating has slow drying, poor hardness, poor weather resistance, high cost and poor washing resistance, and can cause fading or falling off after being used outdoors for a long time, thereby limiting the development of the relief paint.
Therefore, the development of an inorganic fireproof relief coating with high stability, high adhesion and excellent washing and brushing resistance is a technical problem to be solved urgently in the field.

Firstly, the inorganic fireproof relief paint provided by the invention takes potassium silicate colloid and silicic acid colloid as main film forming substances, wherein the potassium silicate colloid and the lithium silicate colloid are pure inorganic substances; the curing process of the potassium silicate colloid is a chemical curing process in which a plurality of chemical reactions are carried out simultaneously, and the cross-linking density after curing is high, so that the adhesive force with the base material is extremely strong, the potassium silicate colloid can enter pores of the base material to play a role in filling the pores, and can also carry out chemical reactions with calcium hydroxide and silicon dioxide in the base material, and the potassium silicate colloid is firmly bonded and cured with the base material by chemical bonds and is fused into a whole, so that the adhesive force between the coating and the base material is further enhanced; the lithium silicate colloid is a compound formed by combining the metal lithium and the silicate structure, has better permeability and film-forming property because the radius of lithium ions is much smaller than that of potassium ions, also has self-drying property, enables water in the coating to evaporate or generate a water-insoluble dry film, and has water irreversibility, so the waterproof effect is particularly obvious, and simultaneously, the stability of the lithium silicate colloid under ultrahigh and low modulus is very excellent, so the long-term storage stability of the coating is improved.

Meanwhile, the organosilicon hydrophobic agent also has good alkali resistance, and still has good storage stability and dilution stability under the alkaline condition.
Finally, the inorganic fireproof relief paint provided by the invention is added with heavy calcium carbonate, quartz sand and mineral wool as fillers, and it is noted that potassium silicate colloid is easy to generate ion reaction with polyvalent metal ions to generate insoluble silicate, so that the paint is thickened and even gelatinized, and the system stability is influenced, therefore, the content of soluble polyvalent metal ions must be strictly controlled by the used fillers.
In conclusion, the inorganic fireproof relief paint provided by the invention is pure inorganic paint, has excellent fire resistance and flame retardance, and after the inorganic fireproof relief paint containing potassium silicate colloid, lithium silicate colloid, organic silicon hydrophobic agent, coarse whiting, quartz sand and mineral wool is applied to the surface of the substrate of the inorganic fireproof relief paint, the concentration of the potassium silicate colloid is increased and the alkalinity is enhanced due to the volatilization of water, so that the dissolving and activating effect of the alkalinity on the lithium silicate colloid is also enhanced, and the binding power of a coating film is further obviously improved; meanwhile, under the strong alkali environment, the organosilicon hydrophobic agent, the potassium silicate colloid, the lithium silicate colloid and the base material are mutually polymerized to form a coating film containing an effective hydrophobic substance, and the coating film is connected with concrete in the base material through a chemical bond, so that the coating film and the base material have high bonding strength, high weather resistance and strong hydrophobic effect, and the effects of protecting buildings and prolonging the service life of the buildings are achieved.
