Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The invention provides an inorganic coating for mineral wool boards, which comprises the following components in parts by weight: 20.15 to 26.4 percent of water, 0.1 to 0.5 percent of modified sodium bentonite, 0.4 to 0.8 percent of dispersant A, 0.1 to 0.3 percent of dispersant B, 0.1 to 0.3 percent of amine catcher, 0.05 to 0.2 percent of defoamer, 1 to 10 percent of titanium dioxide, 1 to 2 percent of ammonia absorbent, 2 to 5 percent of formaldehyde remover, 5 to 8 percent of mineral fiber, 45 to 60 percent of functional filler and 3 to 8 percent of inorganic adhesive.
In order to improve the ventilation effect of the coating, the inorganic adhesive is potassium silicate and modified nano silica sol in a mass ratio of 2:1 are mixed.
The inorganic silicate adhesive is selected from mineral wool coating, so that the vapor permeability of a coating film is improved, when the mineral wool board is finished, residual gas is volatilized in the board due to moisture absorption in a high-temperature and humid area in the south, the gas is quickly volatilized outside the coating, and the gas is volatilized along with flowing air, so that the moisture is prevented from being residual, and the mildew is prevented. Thereby reducing the use of bactericides and reducing the biological pollution to the environment.
Meanwhile, an amine trapping agent and an ammonia gas absorbent are added into the basic formula of the coating, amine gases and ammonia gas volatilized in a coating production line of the mineral wool board and after home decoration are effectively trapped and absorbed, and volatilization of harmful substances in the mineral wool board and generation of unpleasant odor are greatly reduced.
Furthermore, in order to remove volatile organic amine bad smell gas generated by the decomposition of raw materials in the mineral wool board under the high-temperature environment, the amine catching agent consists of benzenesulfonic acid acyl chloride and a wetting agent in a mass ratio of 1. The benzenesulfonic acid acyl chloride is used as an organic amine trapping agent, when the organic amine is generated, the benzenesulfonic acid acyl chloride reacts with the organic amine to generate solid amine, and the solid amine is not easy to volatilize in the air.
In order to increase the dispersibility of the benzenesulfonic acid chloride, the amine scavenger is a liquid material that is more easily dispersed in the coating during production. Meanwhile, in order to improve the dispersity of the benzenesulfonic acid acyl chloride, the wetting agent is any one or more of polyoxyethylene alkylphenol ether, polyoxyethylene fatty alcohol ether and polyoxyethylene polyoxypropylene block copolymer.
Furthermore, in order to remove volatile inorganic ammonia-type unpleasant odor generated by the decomposition of raw materials in the mineral wool board under the high-temperature environment, the ammonia absorbent consists of a molecular sieve and organic salts in a mass ratio of 1. The molecular sieve is natural zeolite. In order to increase the mildew-proof effect of the coating, one or more of organic salts sodium ethoxide.
In conclusion, the organic amine catching agent and the ammonia absorbent are added into the coating, when the organic amine and the ammonia volatilize to the coating under the high-temperature drying condition, the organic amine and the ammonia absorbent rapidly perform adsorption chemical reaction with the amine catching agent and the ammonia absorbent in the coating to generate solid salt, and simultaneously form a compact three-dimensional network structure with the inorganic adhesive, and the three-dimensional network structure ensures that most volatile gas is absorbed in a coating film to form a paint film component in the spraying and drying process of the mineral wool board coating, and the unpleasant gas discharged to the external environment is very little. In southern high-temperature humid areas, because organic amine salt and inorganic ammonia salt in the paint film are strongly combined with silicon oxygen bonds of the inorganic adhesive, the paint film cannot be decomposed for the second time to generate volatile organic amine and inorganic ammonia.
Furthermore, in order to increase the aldehyde removing performance of the mineral wool, the aldehyde removing agent is an organic salt powder material, and the aldehyde removing agent is added in the formula of the mineral wool coating material, so that a paint film has the aldehyde removing performance.
Wherein, the organic salt is one or more of sodium oxalate and ethylamine chloride salt, and active groups in the sodium oxalate and the ethylamine chloride salt can replace active hydrogen in aldehyde group to enable aldehyde substances to generate non-aldehyde substances.
Further, the modified sodium bentonite comprises sodium carboxymethylcellulose, soda ash and sodium bentonite in a mass ratio of 1. Sometimes, the color difference and the effect of paint films of different plates of the same batch of paint are not ensured, and a plurality of times of examination finds that the paint film inconsistency of the type is caused by serious layering of the paint due to the fact that the paint is diluted to the viscosity suitable for automatic spraying before use and a large amount of water is required to be added, so that the solid content of the paint on different mineral wool plates and even the proportion of each component in the paint are changed, and the paint films of different plates are inconsistent. The method for solving the problem is to select the modified sodium bentonite as the modified sodium bentonite, so that the coating has good anti-settling effect when diluted by adding water, and the components in the coating are uniformly distributed. The modified sodium bentonite contains 5 percent of sodium carboxymethylcellulose, 5 percent of soda ash and 90 percent of sodium bentonite, and the raw materials of the modified sodium bentonite, the soda ash and the modified sodium bentonite are uniformly mixed in advance during preparation.
Preferably, in order to reduce the phenomenon of paint film blooming, the functional filler is composed of mica powder, talcum powder and heavy calcium carbonate in a mass ratio of 4. The mica powder, the talcum powder and the heavy calcium carbonate are matched according to the components, so that the light reflection of each point of the paint film is consistent after the paint film is dried, the blooming of the paint film is reduced, and meanwhile, the functional powder material does not contain free polyvalent metal ions.
Because the lower the gloss of the paint film on the surface layer of the mineral wool board, the less obvious the color difference of the paint film of the unit board or the plurality of boards, in order to further reduce the gloss of the paint film, the particle size distribution of the powder material needs to be strictly controlled, and the test data shows that the particle size distribution of the powder material in the formula of the mineral wool board paint is as follows, the gloss of the paint film is proper, and the paint film is uniform and does not bloom: d10 is between 1.3 and 2.8, D50 is between 12 and 18, and D90 is between 30 and 38.
Secondly, by adding the mica powder and utilizing the lamellar structure, the powder material particles and other component particles in the paint are uniformly, stably and scientifically distributed, so that the powder particles in the paint film are arranged alternately, the water is not densely piled under the condition of fast volatilization, and the gloss of the paint film is effectively reduced. Meanwhile, because the particles in the paint film are uniformly distributed and the scattering effect is consistent, the paint film has consistent gloss and does not generate flowers, and in addition, the mica powder can assist in improving the anti-settling property of the paint system.
Further, in order to improve the sound absorption and noise reduction effects of the mineral wool board, the mineral fibers consist of carbon fibers and gypsum fibers in a mass ratio of 1.
In order to improve the solid content in the coating, so that the coating is closed, the basic surface of the mineral wool board covered by the coating is strong in porous rough performance, the paint film is strong in fullness and good in hand feeling, the viscosity of the coating is low to facilitate spraying construction, and the dispersing agent A is sodium polyacrylate; the dispersant B is powdery sodium phosphate.
The water is one or more of drinking water, purified water or deionized water. Water is an indispensable component in mineral wool board coating, and drinking water is selected as a formula component in order to reduce the cost of raw materials.
Preferably, the defoaming agent is liquid organosilicon material, and in order to prevent the paint film sprayed on the mineral wool board from shrinking, the defoaming agent is selected according to the invention.
Preferably, the titanium dioxide is rutile type, and a certain amount of rutile titanium dioxide is added in the formula in order to improve the covering power of the product.

1. the volatilization of harmful gases and bad smelling gases is reduced:

2. the inorganic adhesive forms a compact three-dimensional network structure, most volatile gas is absorbed in the coating film to form a paint film component, volatilization of unpleasant gas is reduced, and organic amine salt and inorganic ammonia salt in the paint film are strongly combined with silicon oxygen bonds of the inorganic adhesive, so that the paint film cannot be decomposed for the second time to generate volatile organic amine and inorganic ammonia.
2. Mildew-proof and antibacterial:
1. the inorganic silicate adhesive is selected from mineral wool coating, so that the coating film has excellent vapor permeability, moisture volatilization is facilitated, and mildew spots are prevented;
2. the inorganic silicate adhesive used has strong alkalinity, and simultaneously has large reaction activity to react with most materials including water, so the mildew-proof and antibacterial properties are extremely excellent, a special mildew preventive and a fungicide are not required to be added, and compared with an organic adhesive coating, the inorganic adhesive coating has good vapor permeability, water vapor in the mineral wool board is quickly volatilized, the time for drying is short, and mildew is not generated in a water-soluble polymer material which is easy to mildew in the mineral wool board because the water vapor in the board is sealed in the inorganic adhesive coating for a long time in a humid environment;
3. the aldehyde removing agent and the ammonia gas absorbent are alkaline, and are effective in mildew prevention and bacteria resistance.
3. Sound absorption performance:
the mineral wool board sound absorption and noise reduction function is improved by adding mineral fibers in the formula.
4. Aldehyde removal performance:
the mineral wool board coating has the aldehyde removal performance mainly by adding the aldehyde removal auxiliary agent in the formula.
5. The decoration effect is good:
1. by adding two dispersants, namely sodium polyacrylate and powdery sodium phosphate, the powdery sodium phosphate dispersant can effectively reduce the viscosity of the coating slurry, improve the solid content under the same viscosity, improve the fullness and dry film covering power of a paint film, and effectively cover the unevenness and porous defects of a substrate, so that the expected paint film effect can be achieved by two-time spraying, and meanwhile, the painting amount of each plate can be reduced to reduce the cost;
2. mineral oil defoaming is added into the paint formula, so that the occurrence of the phenomenon of paint film floating is reduced;
3. by adding the modified sodium bentonite, the layering phenomenon of the paint is reduced, and the color difference and the effect of a paint film are prevented from being caused;
4. the paint film gloss is effectively reduced by strictly controlling the particle size distribution of the powder material and adding the mica powder, and meanwhile, the paint film gloss is consistent and the paint film gloss does not bloom because the particles in the paint film are uniformly distributed and the scattering effect is consistent.

In the invention, the paint is produced by continuously converting the stirring speed of the system, the reactions such as complexation and the like caused by excessive components in the system are prevented, particularly, in the low-speed paint mixing treatment, the ultra-low-speed treatment is needed to add the inorganic adhesive into the homogeneous water slurry for paint mixing, so that the permeability of a paint film channel after the film formation of the paint is improved, and the ventilation effect is improved.
In the preparation method, the adopted materials have extremely high requirements on stirring speed and mixing of the materials, the modified sodium bentonite and the functional filler are required to be prepared at present and have very accurate production proportion, in order to achieve the production effect, the modified sodium bentonite is composed of sodium carboxymethylcellulose, soda ash and sodium bentonite with the mass ratio of 1: 62%:30 percent of mica powder, talcum powder and heavy calcium carbonate.
If a large amount of powder is prepared in advance, the dispersion degree of certain powder in the system is low, and the final production effect is influenced during batch production; if the mixing is directly carried out on site in production, corresponding mixing tools are lacked, and the mixing of the powder is very accurate and difficult to control, so that a production device is also needed to improve the existing production device.
As shown in fig. 2 to 5, the present invention also provides a preparation apparatus of an inorganic coating material for a mineral wool board, comprising a central stirring tank 1, a boundary aggregate component 4 disposed on the central stirring tank 1, and a quantitative blanking component 5 disposed on the boundary aggregate component 4.
The central stirring tank 1 is provided with a stirring chamber 2 for stirring finished products and a variable frequency stirring shaft 3 arranged in the stirring chamber 2, the rotating speed of the variable frequency stirring shaft 3 can be changed along with the change of the production steps, and a plurality of quantitative discharging pipes are communicated with the stirring chamber 2 and used for discharging other types of liquid and other materials.

And the powder materials such as the amine capture agent and the inorganic adhesive and the liquid can be discharged, after the materials are discharged into the boundary aggregate component 4, the materials are uniformly mixed in the boundary aggregate component 4, and after the materials are uniformly mixed, the materials move around the tank opening of the central stirring tank 1, and are gradually discharged into the stirring chamber 2, so that the dispersion degree of the materials in the solution is improved.
And because the inorganic adhesive is subjected to a small amount of dropwise feeding in the paint mixing process, the inorganic adhesive is put into the boundary aggregate component 4 for feeding, so that the requirement of dropwise feeding can be met, other elements for dropwise feeding are not required to be added, and the multipurpose of the boundary aggregate component 4 is realized.

When the aggregate shell 403 is inclined, the feed opening 406 is arranged at the lowest point of the aggregate shell 403, and when the aggregate shell 403 is struck in the moving process, the vibration occurs, so that the materials in the mixing chamber 404 are shaken out from the feed opening 406, and the materials can be concentrated at the bottom of the mixing chamber 404, thereby facilitating the subsequent blanking.
In order to prevent the quantitative blanking assembly 5 from being in a tilting state during blanking, the aggregate shell 403 is also in a tilting state, blanking is inconvenient, a position origin is arranged between the outer ring 4011 and the quantitative blanking assembly 5, a position plate 6 is arranged on the position origin, the position plate 6 is arranged on the supporting rod 4013, the height of the position plate 6 is equal to the distance between the supporting rod 4013 and the aggregate shell 403, when the aggregate shell 403 moves to the position origin, the bottom of the aggregate shell 403 is attached to the upper end of the position plate 6, the position plate 6 is used for righting the aggregate shell 403, each time the aggregate shell 403 passes through the position origin, the aggregate shell 403 is in a horizontal state, and the aggregate shell 403 finishes feeding at the position origin.
