Description
Technical Field
The invention belongs to the technical field of spray putty, and particularly relates to a putty material and a using method thereof.
Background
The putty powder is mainly used for repairing and leveling building walls, in order to meet various requirements, the formula and functions of the putty powder are continuously changed, and functional putty powder such as waterproof, fireproof and moistureproof putty powder is gradually produced in mass, but at present, the so-called fireproof putty is more fireproof by depending on the inorganic material components, rather than the preparation of the putty by adding fireproof and flame-retardant materials. The existing fireproof putty powder is mostly subjected to fireproof flame retardance by adopting a mode of mixing a flame retardant, but the method often causes large putty powder particles in production, the mixing uniformity of the flame retardant and various fillers is poor, and finally, the repairing and leveling effect is poor when the putty powder is coated on a wall, so that the manual scraping time required by the same putty construction is longer, the polishing time is longer due to the unevenness of the dried surface, and the labor cost is greatly increased due to the low construction efficiency; what is more important is that the fireproof and flame-retardant effect of the putty is only slightly better than that of common inorganic putty due to the non-uniform fireproof and flame-retardant auxiliary agent, and the putty is far from being a fireproof and flame-retardant putty in a real sense.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, the invention aims to provide the putty material and the using method thereof, and the putty material has the advantages of fire resistance, flame retardance, convenience in construction, good repairability and the like.
In one aspect of the invention, a putty material is provided. According to an embodiment of the present invention, the putty material comprises: 10-30 parts of aluminum hydroxide powder, 30-50 parts of heavy calcium silicate and 15-25 parts of fumed silica.
According to the putty material provided by the embodiment of the invention, the putty material has the advantages of fire resistance, flame retardance, convenience in construction, good repairability and the like. The aluminum hydroxide powder can generate water vapor after being combusted, the ground limestone can generate carbon dioxide, when the aluminum hydroxide powder and the ground limestone are combusted and react at the same time, the water vapor generated by the aluminum hydroxide powder can carry away part of oxygen along with evaporation and has a certain effect on extinguishing a fire source, and the carbon dioxide generated by the combustion of the ground limestone can carry oxygen away and part of the carbon dioxide is attached to the putty layer to play a role in isolating the oxygen; and part of steam generated by the aluminum hydroxide powder and calcium oxide generated by calcium carbonate combustion form calcium hydroxide, and excessive carbon dioxide forms calcium carbonate, so that the circulation can continuously consume a fire source, and a more excellent flame-retardant effect is achieved. Therefore, the aluminum hydroxide powder and the heavy calcium carbonate can not only form better synergistic flame retardant effect after respective reaction, but also achieve the effect of enhancing fire resistance and flame retardance through partial circulating chemical reaction. And the multiple effects of the two components can be fed back to the fumed silica, so that the fumed silica is subjected to less high-temperature combustion, and the high-temperature resistance and difficult-to-burn performance of the fumed silica further reduces the risk of generating fire sources and combustion objects, and the fumed silica complement each other to achieve better fireproof and flame-retardant effects. Therefore, the aluminum hydroxide, the heavy calcium carbonate and the fumed silica are not simply superposed but interact with each other to produce better closed-loop effects of flame retardance and fire prevention.
Particularly, the fumed silica can form silica sol after being dispersed in water at a high speed, the silica sol has good wall-mounting effect and easy repair of pit defects by utilizing the excellent bonding strength of the silica sol and better mixing effect on other filling aids, and the putty has high temperature resistance of 1500-1600 ℃. The ground calcium carbonate is not combustible and can be decomposed at high temperature to generate carbon dioxide, so that the concentration of oxygen can be diluted, and the effect of inhibiting combustion is achieved. The aluminum hydroxide powder can generate decomposition reaction and absorb heat when being heated, and the concentration of combustible gas can be reduced by water vapor generated after the reaction; in addition, the generated alumina residues are deposited on the surface of the main material, so that the oxygen isolation effect is achieved, and the combustion inhibition effect is achieved.

FIG. 1 is a schematic flow chart of a method for using a putty material according to an embodiment of the present invention.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In one aspect of the invention, a putty material is provided. According to the embodiment of the invention, the putty material comprises 10-30 parts by weight of aluminum hydroxide powder, 30-50 parts by weight of heavy calcium silicate and 15-25 parts by weight of fumed silica. The inventor has surprisingly found through a large number of experiments that if the content of the aluminum hydroxide powder is less than 10 parts, the fireproof flame-retardant coating does not have a good effect; if it exceeds 30 parts, the compactness of the whole coating is insufficient and the structure is loose, resulting in a decrease in the effect of flame retardancy. If the content of the heavy calcium silicate is lower than 30 parts, the compactness of the coating is insufficient, the structure is loose, and the fireproof and flame-retardant performance is reduced; if it is more than 50 parts, workability is impaired and a layered precipitate is liable to occur, resulting in a decrease in various properties of the coating layer. If the fumed silica containsAmounts below 15 parts result in SiO2The particles cannot wrap the coating, so that the adhesion of the coating is affected, and a continuous coating film cannot be formed; if it is higher than 25 parts, the particle wrapping layer can be thickened, the adhesive force of the coating can be reduced, and simultaneously, the volume shrinkage is aggravated due to the increase of viscosity, so that the construction performance and the film forming effect are influenced, and the performance of the coating is further influenced.
According to the putty material provided by the embodiment of the invention, the putty material has the advantages of fire resistance, flame retardance, convenience in construction, good repairability and the like. The aluminum hydroxide powder can generate water vapor after being combusted, the ground limestone can generate carbon dioxide, when the aluminum hydroxide powder and the ground limestone are combusted and react at the same time, the water vapor generated by the aluminum hydroxide powder can carry away part of oxygen along with evaporation and has a certain effect on extinguishing a fire source, and the carbon dioxide generated by the combustion of the ground limestone can carry oxygen away and part of the carbon dioxide is attached to the putty layer to play a role in isolating the oxygen; and part of steam generated by the aluminum hydroxide powder and calcium oxide generated by calcium carbonate combustion form calcium hydroxide, and excessive carbon dioxide forms calcium carbonate, so that the circulation can continuously consume a fire source, and a more excellent flame-retardant effect is achieved. Therefore, the aluminum hydroxide powder and the heavy calcium carbonate can not only form better synergistic flame retardant effect after respective reaction, but also achieve the effect of enhancing fire resistance and flame retardance through partial circulating chemical reaction. And the multiple effects of the two components can be fed back to the fumed silica, so that the fumed silica is subjected to less high-temperature combustion, and the high-temperature resistance and difficult-to-burn performance of the fumed silica further reduces the risk of generating fire sources and combustion objects, and the fumed silica complement each other to achieve better fireproof and flame-retardant effects. The raw materials form a fireproof flame-retardant closed-loop reaction chain, so that the fireproof flame-retardant effect is better.
Specifically, the fumed silica is dissolved in water and can be dispersed at high speed to obtain silica sol, and the silica sol is a refractory material binder, has the characteristic of strong binding power and can resist high temperature of 1500-1600 ℃. Since the silica sol particles are fine (10-20nm) and have a relatively large specific surface area, the particles are colorless and transparent, and the natural color of the covered object is not affected. The water-soluble polymer has low viscosity, and can be penetrated by water, so that the water-soluble polymer has good dispersibility and permeability when being mixed with other substances. When the water in the silica sol is evaporated, the colloidal particles penetrate into the base layer through the capillary and are firmly attached to the surface of an object, and silicon-oxygen bonding reaction occurs among the particles to generate calcium silicate, so that the calcium silicate has strong bonding strength. The coating film is compact and hard, does not generate static electricity, and is difficult to adhere various dust in the air, so the pollution resistance of the coating film is also strong. The aluminum hydroxide powder is used as the flame-retardant filler, and has the characteristics of good thermal stability, no toxicity, no volatilization, small smoke generation amount, good flame-retardant effect and the like. The aluminum hydroxide powder can generate decomposition reaction and absorb heat when being heated, and the concentration of combustible gas can be reduced by water vapor generated after the reaction; in addition, the generated alumina residues are deposited on the surface of the main material, so that the oxygen isolation effect is achieved, and the combustion inhibition effect is achieved. The ground calcium carbonate is not combustible and can be decomposed at high temperature to generate carbon dioxide, so that the concentration of oxygen can be diluted, and the effect of inhibiting combustion is achieved.
In the embodiment of the present invention, the particle size of the aluminum hydroxide powder is not particularly limited, and those skilled in the art can select the particle size according to actual needs, and as a preferable scheme, the particle size of the aluminum hydroxide powder is 200-400 meshes. Through a large number of experiments, the inventor finds that the oil absorption of the aluminum hydroxide powder in the particle size range is relatively small, the influence on the construction viscosity of the putty after being hydrated is not great, and a good apparent effect can be obtained.
In the embodiment of the present invention, the particle size of the heavy calcium carbonate is not particularly limited, and those skilled in the art can select the particle size according to actual needs, and as a preferable scheme, the particle size of the heavy calcium carbonate is 325-600 meshes. Through a large number of experiments, the inventor finds that the oil absorption of the heavy calcium carbonate in the particle size range is relatively small, the influence on the construction viscosity of the putty after being treated with water is not great, and a good apparent effect can be obtained.
Further, the putty material also comprises: an inorganic gel material. The inorganic gel material in the putty material is used as a binder for enhancing the bonding strength of the putty material. The content of the inorganic gel material is not particularly limited, and may be selected by those skilled in the art according to actual needs, and as a preferable embodiment, the content of the inorganic gel material is 15 to 32 parts by weight. Thus, at this ratio, the adhesive strength of the putty material is further enhanced.
In the embodiment of the present invention, the kind of the inorganic gel material is not particularly limited, and may be white cement or ordinary cement. However, portland cement is gray and can affect the appearance of the putty. Compared with common cement, white cement has the advantages of decoration, low price and the like.
Further, the putty material also comprises: and (3) polymer latex powder. The silica sol has larger volume shrinkage in the film forming process, a coating film is easy to crack, and after the polymer latex powder is added, the characteristics of the silica sol and the polymer latex powder complement each other to prepare the organic-inorganic composite coating with excellent performance. The content of the polymer latex powder is not particularly limited, and those skilled in the art can select the polymer latex powder according to actual needs, and as a preferable embodiment, the content of the polymer latex powder is 0.5 to 1.5 parts by weight. A small amount of polymer latex powder can enhance the flexibility of the fumed silica after film formation and reduce cracking, so that the compactness and strength of the putty after a large amount of fumed silica is used are ensured, oxygen which can exist in the putty is reduced, and the flame retardant property is enhanced. The inventor has surprisingly found through a large number of experiments that if the content of the polymer latex powder is less than 0.5 part by weight, the polymer latex powder cannot complement silica sol, so that an organic-inorganic composite coating with excellent performance cannot be prepared; if the amount is more than 1.5 parts, the flame retardant property of the putty material is lowered.
Further, the putty material also comprises: hydroxypropyl methyl cellulose ether, a defoaming agent, a water repellent and a mildew preventive. Therefore, the performance of the putty material is better. The hydroxypropyl methyl cellulose ether plays a role in thickening and water retention in the putty, improves the construction performance, prevents sagging, and enables the inorganic gel material to have enough water for hydration, thereby improving the bonding strength of the putty. The defoaming agent is used for eliminating bubbles generated in the stirring process and the construction process. The water repellent endows the coating film with certain water repellency, thereby improving the water resistance and the washing fastness of the coating film. The mildew inhibitor has the functions of inhibiting the growth of mildew and killing the mildew, so that the high molecular material is protected from being corroded by fungi, and good appearance and physical and mechanical properties are kept.
The contents of the hydroxypropyl methyl cellulose ether, the defoamer, the water repellent and the mildewproof agent are not particularly limited, and can be selected by those skilled in the art according to actual needs, and as a preferable scheme, the content of the hydroxypropyl methyl cellulose ether is 0.3-0.9 part by weight, the content of the defoamer is 0.2-0.8 part by weight, the content of the water repellent is 1-1.5 parts by weight, and the content of the mildewproof agent is 0.3-0.8 part by weight. Therefore, the performance of the putty material is better.
Further, the defoaming agent is polyether modified organic silicon defoaming agent, such as Tianfeng F-1660, Zhongfeo B0518 and B290, Gaoka CK2000 and CK-D045. Therefore, the performance of the putty material is better.
Further, the water repellent is silane-based water repellent, such as Dow Corning SHP50, SHP60, T618, Wake PULVER D, SEAL 80. Therefore, the performance of the putty material is better.
Further, the mildew preventive is nano zinc oxide. Therefore, the performance of the putty material is better.
In yet another aspect of the invention, the invention provides a method of using the putty material described above. According to an embodiment of the invention, with reference to fig. 1, the method comprises:
s100: mixing raw materials except fumed silica
In this step, the raw materials other than fumed silica are mixed so as to obtain a mixed material, and the specific manner of mixing is not particularly limited, and for example, the raw materials may be poured into a mixing device and mixed uniformly. The fumed silica is placed independently, and the fumed silica is light and fluffy, so that the fumed silica is packaged independently, and the uniform stirring is facilitated.
S200: mixing fumed silica with water
In this step, fumed silica is mixed with water and stirred to obtain a silica sol. The reason for the high-speed dispersion of the fumed silica powder by adding water is to obtain silica sol, and the obtained sol is more uniform when being stirred with other powder materials.
The amount of the water is not particularly limited, and can be selected by those skilled in the art according to actual needs, and as a preferred embodiment, the amount of the water is 38 to 45 parts by weight. The inventor finds that if the water content is less than 38 parts, the construction performance is poor and the construction is difficult; if the amount is more than 45 parts, the coating thickness is too large, and sagging tends to occur. The stirring time is not particularly limited, and those skilled in the art can select the stirring time according to actual needs, and as a preferable embodiment, the stirring time is 5 minutes.
S300: mixing the silica sol with the mixed material
In this step, the silica sol is mixed with the mixed material, stirred, left to stand, and stirred again. The stirring time is not particularly limited, and those skilled in the art can select the stirring time according to actual needs, and as a preferable embodiment, the stirring time is 10 minutes. The time for the standing is not particularly limited, and those skilled in the art can select the time according to actual needs, and as a preferable embodiment, the time for the standing is 20 minutes. The time for the re-stirring is not particularly limited, and those skilled in the art can select the re-stirring according to actual needs, and as a preferable embodiment, the time for the re-stirring is 5 minutes.
The method for using the putty material disclosed by the embodiment of the invention has the advantages of simplicity and convenience in construction and good repairing effect. The fumed silica can form silica sol after being dispersed in water at a high speed, and the silica sol has good wall-mounting effect and is easy to repair pitted hole defects by utilizing the excellent bonding strength of the silica sol and better mixing effect on other filler auxiliaries. The heavy calcium silicate has low cost and high whiteness, and the addition of the heavy calcium silicate can reduce the cost, improve the covering power, improve the flowability of the coating and improve the construction performance.

Comparative example 5
The comparative example provides a putty material, which comprises 20 parts by weight of heavy calcium silicate, the other components and the content are the same as those of the putty material in the example 2, and the preparation method and the using method are also the same as those of the putty material in the example 2.
Comparative example 6
The comparative example provides a putty material, which comprises 60 parts by weight of heavy calcium silicate, the other components and the content are the same as those of the putty material in the example 4, and the preparation method and the using method are also the same as those of the putty material in the example 4.
The workability, adhesive strength, repair property, fire rating and mold resistance of examples 1 to 6 and comparative examples 1 to 6 were measured, and the results are shown in Table 1.
TABLE 1
As can be seen from Table 1, examples 1-6 had good workability, no obstacles to blade coating and spray coating, good adhesive strength, and met standard conditions, all fire ratings were A-grade, good refinability, good appearance effect, and no particles. The content of the fumed silica is less than 15 parts, which results in poor repairability, poor surface film forming property and uneven appearance on the one hand, and poor fireproof and flame-retardant effects and reduced fireproof grade on the other hand. The comparative example 2 comprises 5 parts by weight of polymer latex powder, and other conditions are the same as those of the example 1, and the comparison between the example 1 and the comparative example 2 shows that if the content of the polymer latex powder is more than 1.5 parts, the fireproof and flame retardant properties of the putty material are affected, so that the fireproof grade of the putty material is reduced. The aluminum hydroxide powder of 5 parts by weight is contained in comparative example 3, and other conditions are the same as those of example 4. it can be seen from comparison between example 4 and comparative example 3 that, if the content of the aluminum hydroxide powder is less than 10 parts, it does not have a good effect on fire retardancy, resulting in a decrease in fire-retardancy. The aluminum hydroxide powder of 35 parts by weight is contained in comparative example 4, other conditions are the same as those of example 5, and it can be seen from comparison between example 5 and comparative example 4 that if the content of the aluminum hydroxide powder is higher than 30 parts, the compactness of the whole coating is insufficient, the structure is loose, and the effect of fire-retardant and flame-retardant is reduced. The 20 parts by weight of heavy calcium silicate is contained in the comparative example 5, and other conditions are the same as those of the example 2, and it can be seen that the comparison between the example 2 and the comparative example 5 shows that if the content of the heavy calcium silicate is less than 30 parts, the compactness of the coating is insufficient, the structure is loose, and the fireproof and flame retardant performance is reduced. In comparative example 6 in which 60 parts by weight of heavy calcium silicate was contained, and the other conditions were the same as in example 4, it can be seen from examples 4 and 6 that if the content of heavy calcium silicate is more than 50 parts, workability is impaired and layered precipitation is easily generated, thereby causing deterioration of various properties of the coating layer.
