Disclosure of Invention
The invention aims to provide a preparation method of a water-based inorganic nano-silica granite coating, which is simple in preparation process and high in quality controllability by optimizing the selection of raw materials and combining the improvement of the process compared with the existing preparation method.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
a preparation method of a water-based inorganic nano-silica granite coating comprises the following steps:
s1, preparing a component A;
the raw materials comprise the following components in parts by weight:
0.5-1 part of guar gum modified hydroxyethyl cellulose
20-30 parts of pigment and filler
3-8 parts of component A additive
20-30 parts of inorganic nano silicon resin
10-20 parts of inorganic lithium silicate
5-10 parts of inorganic silica sol resin
10-20 parts of natural colored sand and carborundum with 100 meshes;
the mass ratio of the natural colored sand to the carborundum is 2: 1;

s2, preparing a component B;
the raw materials comprise the following components in parts by weight:
20-30 parts of inorganic magnesium lithium silicate
2-4 parts of anhydrous sodium pyrosulfate;
after the raw materials of the component B are put into a dispersion kettle and heated to 80-90 ℃, the raw materials are dispersed for 30-40 minutes at the speed of 500-800r/min, and after the temperature is reduced to 25 ℃, no particle paste is reserved;

the raw materials comprise the following components in parts by weight:
6-10 parts of component C auxiliary agent
20-30 parts of inorganic nano silicon resin
10-20 parts of carborundum with 100 meshes;
after all the raw materials of the component C are put into a dispersion kettle, dispersing for 10-15 minutes at the speed of 500 plus materials/min, and keeping no particles for later use;
s4, preparing a mixture;
the mixture comprises the following components in parts by weight:
50-70 parts of component A
20-30 parts of component B
20-30 parts of a component C;
adding the component A into the component B, dispersing for 3-5 minutes at 500-800r/min to form a shape, adding the component C, and uniformly mixing to obtain a finished product of the aqueous inorganic nano silica sand stone coating.
Compared with the traditional real stone paint: the granite coating of the invention does not need to store a large amount of sandstone, and the paint film is weather-proof and crack-resistant and is not easy to generate efflorescence; the paint consumption is as low as 0.5 to 1kg per square, and a paint film is light, resistant to pollution and self-cleaning; the stone imitation is vivid and the decoration effect is excellent.
Compared with sand-in-water: the granite coating has simple color matching and convenient granulation. The paint can be fully sprayed into small and fine granite with good self-cleaning performance and clean and fresh after rain. The paint film is light, pollution-resistant, self-cleaning, ultraviolet-resistant and not easy to fade.
The rough grit coating is prepared by dividing the raw materials into a component A, a component B and a component C of a three-component system, and the preparation of the component A, the component B, the component C and a mixture can be synchronously carried out in the process, so that the batching time and the production time are obviously reduced relatively, the production efficiency is improved, and the cost is reduced. Meanwhile, the component A is a color blending component, the component B is particles for isolating different colors in the component A, and the component C is an inorganic binder for binding and film forming; the preparation method has the advantages that the raw materials are separately prepared and mixed according to the characteristics of the raw materials, so that the errors in the production process can be conveniently and timely found and adjusted, the dispersion is easier and uniform, the preparation process is simple, and the quality controllability is high. In the component B, the main component of the separant is artificially synthesized magnesium lithium silicate which is a trioctahedral layered silicate mineral. Because the surface of the slice is negatively charged and the end surface is positively charged, the end surface of the separated slice is attracted to the surface of the other slice, thereby quickly forming a colloid structure of a three-dimensional space, namely a card palace structure, namely the function of forming gel protection color particles. As the quartz sand with larger grain diameter exists in the color point of the granite coating, the protective glue is difficult to form a continuous gel film to coat color particles in the process of cutting point granulation, and further, substances and color paste in the base paint overflow to a continuous phase to influence the performance and the hue of the base paint. Based on the characteristics of the granite coating, the commercially available protective glue is adopted for comparison, and the experiment shows that: through a special surface treatment process, a card palace structure is formed on the surfaces of the multicolor particles by using the organically modified grid protective adhesive RDS, so that an interconnected network body formed by the organic body is increased, a good protection effect is achieved on multicolor particles with larger particle sizes in the aggregate paint, and the aggregate paint has good color permeation resistance.
The invention has undergone a great deal of research and practice in the selection of specific raw materials. The guar gum modified hydroxyethyl cellulose is a mixture of hydroxyethyl cellulose, guar gum and a hydrophobic agent, improves the construction performance and the water resistance of the coating, and adopts HEC28000 produced by Abel chemical Co., Ltd. in Fushan; the inorganic nano silicon resin, namely the inorganic composite silicon hybrid resin, improves the toughness of the coating and resists cracking; the inorganic lithium silicate plays a role in calcification and improves the hardness; the inorganic silica sol resin plays a role in the latitude of color matching. Particularly, natural colored sand and carborundum are mixed to obtain main colored sand and delicate pockmarks.
Compared with the stone paint, the granite coating has the following advantages:
(1) the granite and sandstone feel is strong and the imitation stone is vivid
Real stone paint: the stone-like paint is affected by the color of natural color sand, and has single color, so that its stone-like variety has certain limitation, and only can be used for imitating hue and texture, and its pattern can not be reflected completely.
Sandstone: the granite is a water-based sand-containing colored point, the color can be manually adjusted, and the color is simpler than that of multicolor paint! The color is rich and full, and the stereovision of the patterns is high.
(2) The cracking resistance of the sandstone is excellent
Real stone paint: the content of the medium-high grade real stone paint emulsion is usually about 15%, and the medium-high grade real stone paint emulsion is rigid after being dried and has poor crack resistance. The stone-like paint has entered into the endless loop of low quality, low price winning and low price competition, from product quality to construction quality is affected!
Sandstone: the selected inorganic composite resin of the granite is purely natural, the quality is far higher than that of products such as real stone paint, texture paint and the like, the main color is combined with the exquisite granite and the natural color sand through a special modification technology, the content of the inorganic composite resin of the granite is high, the adhesive force is higher, and more complex weather can be effectively resisted.
(3) The contamination resistance of the sandstone is far higher than that of the stone paint
Real stone paint: the surface concave-convex feeling is too strong, and meanwhile, because the content of the emulsion is low, no effective film is formed between the colored sands, dust can permeate into the coating, and the coating is not easy to clean.
Sandstone: although the surface is also in a small-particle concave-convex state, the inorganic composite resin completely wraps the colored sand, and the colored sand effectively forms a film, so that dust only floats on the surface, and the dust can be washed clean after raining.
(4) The unique breathing performance of the granite ensures that the building really' lives up
Real stone paint: the sand wall-shaped formula has certain air permeability, but because the content of the emulsion is too low, a film cannot be effectively formed between the colored sands, and in addition, the coarse sand grains are too much, and the hidden trouble of water seepage exists in the film coating.
Sandstone: the paint belongs to a sand wall-shaped inorganic composite formula, has certain air permeability, has smaller and uniform color sand grain diameter ratio due to limited sand content, can achieve the breathing and waterproof performance after film formation, and better adjusts the state of the outer facade of a building!
(5) Convenient construction of the granite is low in cost
Real stone paint: in order to achieve a better stone simulation effect of the real stone paint, multi-gun construction is often used in the past, or water-in-water paint is sprayed on the basis of the real stone paint, so that the construction amount is increased, the construction efficiency is influenced, and the construction labor and materials are increased.
