The present invention relates to a nonflammable composition liquid for imparting nonflammability to building materials, and more particularly, to a nonflammable composition liquid for imparting incombustibility to building materials, and more particularly, to a nonflammable composition liquid for imparting incombustibility to building materials by mixing with raw materials in the production of building materials such as incombustible insulation materials used in the dry bit process, filling materials for sandwich panels, ≪ / RTI > In addition, the building material made of the incombustible composition liquid containing the main incombustible composition magnesium chloride and mixed with the natural resin, such as rosin and glue, can secure excellent physical properties. In order to realize more excellent nonflammability, zeolite silicate And a nonflammable composition liquid for building materials containing hydrate.
As a building becomes bigger and bigger, a fire in a building often leads to a major accident. Because of this, firefighting standards are being reinforced, and the standards for nonflammability and flammability of building interior materials and other facilities are also being strengthened.
Fire retardant paints are paints that are applied to inflammable materials such as wood, foam sponge, and plastic to prevent ignition or delay ignition time. There are two types of such fire-resistant coatings: one made of a non-flammable or flame-retardant material; one foamed when heated to form a barrier layer with the flammable material to block the flame and delay heat conduction.
The former is a flame-retardant material such as water glass, various kinds of flame-retardant or incombustible resin, and chlorine compound, and various pigments and fire-proof powder are added. In the latter, a synthetic resin is used as a binder and various refractory agents, a foaming agent, an adiabatic carbonization agent, a carbonization promoter and the like are added to thermally decompose the coating film by heating to generate incombustible gas and a heat insulating layer foamed in a sponge- Lt; RTI ID = 0.0 > flame < / RTI >
The following are representative conventional techniques for nonflammable compositions that can be used for building materials.
Korean Patent No. 10-0996720 relates to a composition for forming a nonflammable coating film and a nonflammable coating film obtained therefrom, the composition comprising (a) at least one binder resin selected from a water-soluble or water-dispersible acrylic resin and a water-soluble or water- To 64.8 wt%; (b) 19.6-25.2 wt% water; (c) 6 to 26% by weight of expandable graphite; And (d) 2 to 4% by weight of black soybean oil.
The composition for forming a nonflammable coating film having the above-described composition realizes an effect of having excellent nonflammability due to the action of expansive graphite.
However, since the conventional non-combustible composition has properties such that graphite or magnesium chloride, which is generally used, is heated by a flame and damages other cured compositions and is thrown out to the outside, continuous research and development .
DISCLOSURE OF THE INVENTION The present invention has been made in order to solve the problems of the conventional incombustible composition liquid for building materials. The conventional incombustible composition for building materials uses magnesium chloride as a composition for realizing merely nonflammability. However, Magnesium has the problem of damaging other compositions of building materials such as Styrofoam when heated and having the property of bouncing out of the building material;
The building material damaged by the magnesium chloride of the nonflammable composition liquid has been sharply reduced in volume to lose its functionality as a nonflammable thermal insulator or filler;
Since a large number of toxic substances are contained in the nonflammable composition, there is a problem that the emergency can not escape from the fire site due to the toxic substances generated due to the fire caused by the fire due to the fire. It is the main purpose.
The present invention has been made to solve the above-
1.0 to 3.0% by weight of gypsum, 1.0 to 4.0% by weight of glue, 5.0 to 9.0% by weight of sodium hydroxide, 3.0 to 5.0% by weight of sodium tertiary phosphate, 0.1 to 1.0% by weight of ammonia, 7.0 to 12.0% by weight of emulsifier, To 82.0% by weight; 1 to 10 parts by weight of the first solution, 85 to 99 parts by weight of magnesium chloride and 1 to 10 parts by weight of zeolite-based silicate hydrate are mixed with 100 parts by weight of distilled water.
In the non-combustible composition according to the present invention as described above, when heat is applied to the magnesium chloride, the rosin and glue contained in the first solution damage the other composition and prevent the spring of the building material from being thrown out Can be obtained;
Even when heat is applied, magnesium chloride of the nonflammable composition liquid does not damage the other composition and composition of the building material, thereby solving the problem of reducing the volume of the building material such as styrofoam;
The noncombustible composition does not contain any toxic substance, so that even if the building material is burned due to fire, it is possible for the emergency person to suck less toxic gas and to escape more easily at the fire scene.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a composition of a nonflammable composition liquid for building materials according to a preferred embodiment of the present invention; FIG.
The present invention relates to a nonflammable composition for imparting nonflammability to a building material, which comprises 1.0 to 3.0% by weight of a liquid phase, 1.0 to 4.0% by weight of glue, 5.0 to 9.0% by weight of sodium hydroxide, 3.0 to 5.0% 0.1 to 1.0% by weight of ammonia, 7.0 to 12.0% by weight of an emulsifier, and 68.0 to 82.0% by weight of distilled water; Wherein the first solution is prepared by mixing 1 to 10 parts by weight of the first solution, 85 to 99 parts by weight of magnesium chloride, and 1 to 10 parts by weight of a zeolite-based silicate hydrate with respect to 100 parts by weight of distilled water.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
First, the nonflammable composition liquid according to the present invention is mixed with raw materials of heat insulating materials or fillers used for building materials such as incombustible insulation materials used in the dry bit process, fillers for sandwich panels or fillers for fire doors, etc., thereby improving the incombustibility of finished building materials .
Specifically, the first solution is configured such that magnesium chloride and zeolite-based silicate hydrate which realize the main incombustibility can be easily dispersed and mixed, and a certain physical strength can be exhibited when the incombustible composition is cured .
That is, the liquefaction of the liquid phase included in the first solution improves the physical strength of the building material including the incombustible composition, and when the magnesium chloride mixed with the incombustible composition is heated, Which damages the composition and prevents it from splashing out of the building material.
The rosin is a sticky brownish sticky liquid coming from the stem of the tree attached to the pine tree. When it comes out from the damaged part of the tree, it is a colorless transparent liquid, but volatile material evaporates over time and becomes sparse and sticky . In addition, rosin is soluble in ethyl alcohol, acetic acid or chloroform, but does not dissolve in water.
In addition, it is preferable that the liquid phase is included in the first solution in a composition of 1.0 to 3.0% by weight. If the liquid phase includes less than 1.0% by weight of the liquid phase, the physical strength of the building material There is a problem in that the effect of preventing magnesium chloride is insufficient. When it exceeds 3.0% by weight, there is a concern that the resin may accelerate the fire rather than the resin, so that the resinous phase of the liquid phase is contained in the first solution .
The liquid phase in the present invention can be produced by various treatment methods, but it can be produced by using 25.0 to 33.0% by weight of purified rosin, 0.5 to 2.5% by weight of DEG (diethyleneglycol) 1.0 to 3.0% by weight of middle chain length triglyceride (MCT), 1.5 to 3.5% by weight of dioctyl terephthalate (DOTP), 37.0 to 50.0% by weight of isopropyl alcohol (IPA) And 15.0 to 30.0% by weight of methanol are mixed with stirring.
That is, the purified resin is obtained by collecting and distilling the natural resin resin, and if the collected resin is distilled, the low molecular substance contained in the resin can be volatilized more quickly and effectively to obtain the purified resin resin having excellent adhesion, cohesion and water resistance .
It is preferable that the purified pine resin be mixed at a composition ratio of 25.0 ~ 33.0 wt% with respect to the liquid pine resin. If the amount of the purified pine resin is less than 25.0 wt%, the composition of the purified pine resin for the pine resin is insufficient, The effects of improving the physical strength of the building material by the magnesium chloride and the effect of preventing damages to other compositions of the building material by the heated magnesium chloride are insufficient. When the content exceeds 33.0 wt%, the above- It is preferable that the refined propagation is included in the liquid phase in the composition ratio within the above range.
Further, the diethylene glycol is a kind of dihydric alcohol and is a constitution for stabilizing the liquid phase resin mixed with the purified rosin, heavy chain fatty acid, dioctyl terephthalate, isopropyl alcohol and methanol. If diethylene glycol is contained in an amount of less than 0.5% by weight, the effect of stabilizing the liquid phase in the liquid phase by diethylene glycol is insufficient, and if diethylene glycol is contained in the liquid phase, When ethylene glycol is contained in an amount of more than 2.5% by weight, the adhesive strength, cohesive force and waterproofing power of purified rosin become weak. Therefore, diethylene glycol is preferably included in the liquid phase in the composition ratio within the above range.
Further, the heavy chain fatty acid and dioctyl terephthalate serve as a plasticizer when the building material is manufactured using the incombustible composition liquid according to the present invention which includes the liquid phase of the resin.
That is, the heavy chain fatty acid may be mixed separately when the first solution or the incombustible composition liquid is prepared, but when the purified lactic acid is mixed with the liquid resin, the plasticity of the refined resin can be improved. The medium chain fatty acid (middle chain length triglyceride (MCT)) generally has 8 to 12 carbon atoms.
When the medium chain fatty acid is mixed at less than 1.5% by weight in the liquid phase, the effect of improving the plasticity due to the medium chain fatty acid is insufficient. When the medium chain fatty acid is mixed with 3.5 wt% %, The plasticity is improved but the physical properties of the finished building material are lowered. Therefore, it is preferable that the heavy chain fatty acid is included in the liquid phase in the composition ratio within the above range.
In connection with the above, dioctyl terephthalate may also be mixed separately in the preparation of the first solution or the incombustible composition liquid, but when mixing the purified tin resin into the liquid tin resin, the effect of improving the plasticity of the purified tin resin I will exert.
At this time, it is preferable that dioctyl terephthalate is mixed at a composition ratio of 1.5 to 3.5 wt% in the liquid phase of the resin. If dioctyl terephthalate is mixed in less than 1.5 wt% in the liquid phase, If the content exceeds 3.5% by weight, plasticity is improved, but the physical properties of finished building materials are deteriorated. Therefore, it is preferable that dioctyl terephthalate is included in the liquid phase in the composition ratio within the above range.
In addition, the isopropyl alcohol and the methanol are dissolved in the refined resin to make it in a liquid state, and at the same time, the purified resin can be dissolved in the following distilled water.
In this case, mixing the different types of alcohols serving as the solvent of the purified pine rosin improves the solubility of the purified pine in methanol, but if the composition of methanol exceeds 30.0 wt% of the liquid pine, the physical properties of the purified pine , So isopropyl alcohol is mixed and used.
That is, when isopropyl alcohol is mixed in less than 37.0% by weight of the liquid phase, the methanol is more than 30.0% by weight and the physical properties of the purified liquid tin dissolved by the solvent are lowered. By weight, the content of methanol is less than 15.0% by weight and the refined resin is insufficiently dissolved. Therefore, the isopropyl alcohol content is 37.0 to 50.0% by weight and the methanol content is 15.0 to 30.0% by weight It is preferable to mix it with the liquid resin.
In addition, the liquid phase of the liquid phase, which is prepared by mixing refined resin, diethylene glycol, heavy chain fatty acid, dioctyl terephthalate, isopropyl alcohol, and methanol, can be prepared by stirring and mixing in a conventional manner. However, Heated to a temperature of 100 to 140 ° C and stirred for 0.5 to 2 hours to be made into a liquid resin.
At this time, if the heating temperature of the mixture for making the liquid phase is less than 100 캜, the heating temperature is low and the heating time exceeds 2 hours, resulting in poor economical efficiency. If the heating temperature exceeds 140 캜, But since the heating temperature is excessively high, there is a fear that the liquidus in the liquid phase will deteriorate and be damaged. Therefore, it is preferable that the mixture for making the liquid phase in the liquid phase is subjected to heat treatment with stirring for the above-mentioned time within the above range.
In addition, the glue is an extract obtained by using the animal's leather or bone as a raw material in order to improve the physical strength such as tensile strength and compressive strength of the building material contained in the incombustible composition together with the liquid phase.
That is, in general, in the case of extracting glue using leather, the leather is immersed in a lime solution and then subjected to hot water extraction. When the extracted solution is concentrated and cooled, a solidified glue is formed. When bone is used to extract glue, the bone is pre-degreased with an organic solvent, hot-extracted, and the extracted solution is concentrated and cooled to form a solidified glue.
It is preferable that the glue is contained in a composition of 1.0 to 4.0% by weight with respect to the first solution. When the glue is contained in an amount of less than 1.0% by weight, physical strength such as tensile strength and compressive strength If the content exceeds 4.0% by weight, the finished building material may become excessively hard and cracks may occur. Therefore, it is preferable that the glue is included in the first solution at the composition ratio within the above range.
In addition, sodium hydroxide is preferably contained in the composition in an amount of 5.0 to 9.0% by weight based on the amount of the first solution to adjust the pH of the first solution to stabilize the liquid phase in the distilled water.
If sodium hydroxide is contained in an amount of less than 5.0% by weight, the basicity of the nonflammable composition is somewhat weak, so that the liquid phase of the resin is less dissolved and poorly dissolved in the distilled water contained in the first solution, The basicity of the produced non-combustible composition is excessively high, so that the property of the other composition of the building material mixed with the non-combustible composition is deformed, so that sodium hydroxide is contained in the first solution at the composition ratio within the range .
In addition, sodium tertiary phosphate is added to the first solution so as to adjust the pH of the first solution to stabilize the liquid phase in the distilled water by rosin, and is contained in a composition of 3.0 to 5.0 wt% .
If sodium tertiary phosphate is contained in an amount of less than 5.0% by weight, the basicity of the nonflammable composition is somewhat weak, so that the liquid phase of the rosin and the glue are less dissolved and poorly limited in the distilled water contained in the first solution. The basicity of the produced non-combustible composition is excessively high, and there arises a problem that the properties of the other composition of the building material mixed with the non-combustible composition are deformed, so that the sodium tertiary phosphate has a composition ratio 1 < / RTI > solution.
That is, the sodium hydroxide and the tribasic sodium phosphate are components for adjusting the pH of the first solution. In order to adequately secure the liquid phase of the distilled water and the solubility of the glue, strong bases of different kinds are added to the first solution .
In addition, ammonia is a constituent for appropriately neutralizing the first solution having a basicity by the sodium hydroxide and the trisodium phosphate. The ammonia is used in an amount of 0.1 to 1.0 wt% based on the composition of sodium hydroxide and trisodium phosphate contained in the first solution, Is contained in the first solution.
At this time, the ammonia is configured to be able to adjust the final pH of the first solution as ammonia by mixing the first solution with the liquid phase after the lyophilization and the glue are appropriately dissolved in the distilled water containing sodium hydroxide and sodium tertiary phosphate .
The composition ratio of ammonia to the first solution may vary depending on the composition ratio of sodium hydroxide and sodium phosphate to be contained in the first solution. However, the ratio of ammonia to the first solution may be 0.1 By weight to 1.0% by weight.
In addition, the emulsifier is constituted to dissolve the oil component which may be contained in the liquid phase of the rosin or glue in the distilled water, and since the rosin or glue is a natural component, a slight oil component may be contained even if purified ones are used.
On the contrary, the emulsifier realizes an effect of emulsifying the distilled water and the oil component to prevent the oil component from floating in the first solution. In this case, the emulsifier is preferably mixed at a composition ratio of 7.0 to 12.0 wt% with respect to the first solution, and the emulsifier can be freely adjusted within the range of the composition ratio according to the purity of the rosin and the purity of the gypsum contained in the rosin.
In addition, any one or more of commonly known emulsifiers can be used as the emulsifier, but any one or more of acetone, hexan-3-one or 3-bromo-cyclohexanone may be used in the present invention. The above-mentioned ketone-based emulsifier does not impair the inherent properties of the rosin and glue, and exerts the effect of stably emulsifying the oil component contained in the rosin and glue with the distilled water.
In addition, the first solution, which is composed of a liquid phase of rosin, glue, sodium hydroxide, sodium triphosphate, ammonia and an emulsifier, dissolves the compositions using distilled water as a solvent. At this time, distilled water may be contained in the first solution at a composition ratio other than the composition ratio of the first solution, but it is preferably contained in a composition of 68.0 ~ 82.0 wt%.
Further, the first solution made of the above composition is mixed with distilled water, magnesium chloride and zeolite-based silicate hydrate, and made of incombustible composition liquid for building materials.
That is, the first solution described above is configured such that the magnesium chloride and the zeolite-based silicate hydrate capable of realizing the main incombustibility can be dispersed and mixed easily and exhibit a certain physical strength when the incombustible composition is cured.
In addition, magnesium chloride is known as a material for realizing incombustibility when it is included in a composition of building materials, and in the present invention, it is a main composition for realizing incombustibility together with zeolite-based silicate hydrate.
At this time, the saltiness of the incombustible composition liquid varies depending on the composition ratio of magnesium chloride, and it is preferable that the incombustible composition solution according to the present invention has a salinity of 20 to 30 ‰. That is, if the nonflammable composition liquid contains a large amount of magnesium chloride, the incombustibility due to the magnesium chloride is improved. However, due to the composition of the excessive magnesium chloride, the magnesium chloride is heated during the fire to damage the other composition, The magnesium chloride is preferably contained so that the saltiness of the incombustible constituent liquid is 30 ‰ or less.
Specifically, magnesium chloride is preferably mixed in a composition ratio of 85 to 99 parts by weight with respect to 100 parts by weight of distilled water contained in the incombustible composition liquid. When the magnesium chloride is contained in an amount of less than 85 parts by weight, the salinity is maintained at less than 20% However, when the amount of magnesium chloride exceeds 99 parts by weight, the incombustibility due to magnesium chloride is improved. However, when the salt content is less than 30 ‰ It is preferable to maintain the composition ratio within the above range because magnesium chloride causes a problem that the other composition of the building material is damaged by the salt.
In addition, the zeolite-based silicate hydrate contained in the nonflammable composition liquid is an inorganic mineral, so it is not ignited by the heat generated by the fire, and thus it is used as an excellent nonflammable material. The zeolite silicate hydrate has various structures and pore sizes depending on the kind. In the present invention, various kinds of zeolite silicate hydrates may be used depending on the kind of building material including the incombustible composition liquid.
In connection with the above, a zeolite-based silicate hydrate in which a functional group such as a hydroxyl group exposed to the surface (including pores) of a zeolite-based silicate hydrate is replaced with a metal may be used to realize more excellent nonflammability.
That is, when the functional group such as the hydroxyl group of the zeolite silicate hydrate of the present invention is substituted with Cu, Co, Fe, Ni or Zn, the effect of reducing the pore size of the zeolitic silicate hydrate, The nonflammability of the incombustible liquid can be further improved.
The zeolite-based silicate hydrate may be at least one of the faujasite (FAU), chabazite (CHA) or ferrierite (FER) structure types.
As the spore-forming zeolite, any one of substituted or unsubstituted zeolites X, Y and SAPO-37 can be used. As the zeolite having a chabazite structure, substituted or unsubstituted AlPO-34, CoAPO-44, CoAPO-47 SAPO-34 and SAPO-47 can be used. As the ferrierite type zeolite, any of ZSM-35 and NU-23 which is substituted or unsubstituted can be used.
That is, the spore-shaped zeolite-based silicate hydrate has a three-dimensional pore structure having pores of about 7 to 8 Å, and the zeolite-based zeolite-based silicate hydrate has a pore structure of about 7 to 8 Å And the ferrierite type zeolite-based silicate hydrate has a two-dimensional structure as compared with the spore-site type or chabazite-type zeolite-based silicate hydrate, and has a relatively small size of about 3 to 4 angstroms .
Since the zeolite-based silicate hydrate of the faujasite (FAU), chabazite (CHA) or ferrierite (FER) structure having the above-described structure is very small in pore size, Even if another composition is ignited, the supply of oxygen to the composition of the surrounding zeolite-based silicate hydrate is blocked, thereby exerting an effect of blocking ignition of the building material.
In addition, zeolite-based silicate hydrates having various particle sizes may be used depending on the use of the incombustible composition liquid, but those having an average particle diameter of 10 to 400 탆 are preferably used.
The zeolite-based silicate hydrate is preferably mixed at a composition ratio of 1 to 10 parts by weight with respect to 100 parts by weight of distilled water contained in the incombustible composition liquid. When the zeolite-based silicate hydrate is mixed in an amount of less than 1 part by weight, the effect of improving the incombustibility due to the zeolite-based silicate hydrate is insufficient. When the zeolite-based silicate hydrate is mixed in an amount exceeding 10 parts by weight, It is preferable that the zeolite-based silicate hydrate maintains the composition ratio within the above-mentioned range.
The following is a nonflammable and gas hazard test of the nonflammable composition liquid prepared and produced according to the present invention.
