The present invention relates to a heat insulating material for building materials having a nonflammable property, and more particularly, to a heat insulating material for building materials having a nonflammable property, and more particularly to a heat insulating material for building materials having a nonflammable property, The fibrous yarn is used to increase the strength of the heat insulating material by increasing the bonding force between the foamed synthetic resin in the granular form and to form the filler layer in the form of a board as the fabric layer and to increase the strength of the heat insulating material. Non-combustible insulation material and a method for producing the same.

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.

The general styrofoam used as a heat insulating material is also called a polystyrene foam or expanded poly-styrene (EPS). It is made of expanded polystyrene with a foaming agent and is lightweight, waterproof, heat insulating, And is widely used for various packaging materials, building materials, daily commodities and the like.

Although these styrofoames function as insulation, they are always in trouble when they are constructed, but they are inevitably constructed, but they are susceptible to fire due to chemical products, so they must be installed between walls and walls of the building, In order to strengthen the pressure during the floor construction due to weakness of problems and pressure, it is necessary to take out the cement pillar by removing the hole between the cement potholes. Therefore, there is a problem in that the energy efficiency is low due to heat leakage, There was a problem in that the cost of extending the air was increased.

The following are representative prior arts for incombustible insulation materials for building materials.

In addition, the above-mentioned prior art can prevent the styrofoam from easily dissolving at the initial stage of the fire, thereby delaying the generation of toxic gas. However, the manufacturing process is somewhat complicated and the bonding force between the styrofoam particles forming the styrofoam block is insufficient There is a problem that the durability is somewhat deteriorated. Therefore, there is a need for continuous research and development to solve this problem.

In the conventional incombustible insulation material for building materials, merely a foamed synthetic resin such as styrofoam is adhered using an incombustible adhesive However, there is a problem in that the strength of the heat insulating material is somewhat lowered due to insufficient binding force between the foamable synthetic resin and granular phase;

Particularly, the main object of the present invention is to provide a solution to the problem that the particles of the foamable synthetic resin which are exposed to the outside of the heat insulating material are easily dropped due to external force, in the heat insulating material produced by mixing the foamed synthetic resin and the non- .

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a non-combustible insulation material for building materials.

The present invention relates to a heat insulating material for building materials having a nonflammable property.

Further, the heat insulating material manufactured according to the present invention can be used for the incombustible heat insulating material used in the dry bit process, the fill material for the sandwich panel, the filler for the fire door, and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 and 2 showing embodiments of the present invention, by separately distinguishing a nonflammable insulation material for building materials and a nonflammable insulation material manufacturing method for buildings.

[Nonflammable Insulation for Building Materials]

The present invention relates to a filler layer (10) formed by curing a filler mixture composed of fiber yarn, granular foamable synthetic resin, and incombustible liquid; And a fabric layer (20) bonded to the upper and lower surfaces of the filler layer (10).

That is, the incombustible insulation material (hereinafter, referred to as 'insulation material') for building materials according to the present invention comprises a filler layer 10 and a fabric layer 20 macroscopically.

Specifically, the filler layer 10 is located inside the heat insulating material, and is formed by curing a filler mixture comprising fiber yarn, granular foamable synthetic resin, and fire-retardant liquid.

The fiber yarn included in the filler mixture may be a glass material, a natural material, or a synthetic resin material having a predetermined length. Preferably, the fiber yarn is made of glass wool, cotton yarn, or synthetic resin having a larger physical strength than a foamable synthetic resin material, Or one or more of the following materials.

In addition, the length of the fiber yarn may be an appropriate size depending on the particle size of the expandable synthetic resin contained in the filler mixture. Preferably, when the average particle diameter of the expandable synthetic resin is 1 to 5 mm, the average length of the fiber yarn is 5 to 20 mm , The foamable synthetic resin particles which are granularly adhered by the incombustible fluid can be constituted so that the adjacent expandable synthetic resin particles can be bound to each other by the fiber yarn.

The particulate expandable synthetic resin contained in the filler mixture may be a granule having a predetermined diameter, and may preferably be composed of one or more materials selected from the group consisting of a polyolefin resin foam, a polystyrene foam, and a polyurethane foam.

That is, the foamed synthetic resin having the above-described constitution realizes the main heat insulating property of the heat insulating material and can be composed of the same composition as the general heat insulating material. The foamed synthetic resin may be the same as styrofoam, and the styrofoam may be a particle of new or refined product (abandoned product), preferably having an average particle diameter of 1 to 5 mm or less.

Further, the incombustible liquid contained in the filler mixture allows the filler mixture to have a certain adhesiveness so that the fiber yarn and the foamable synthetic resin particles can be adhered to each other, and the incombustibility prevents the heat insulating material from easily burning when a fire occurs .

That is, a known incombustible adhesive may be used as the incombustible liquid, and a non-combustible liquid according to Korean Patent Publication No. 10-2015-0078186 filed by the present inventor may be used.

Specifically, the incombustible liquid of the above-mentioned constitution is composed of 1.0 to 3.0% by weight of the 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% by weight of sodium tertiary phosphate, 7.0 to 12.0% by weight of an emulsifier and 68.0 to 82.0% by weight of distilled water; 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, based on 100 parts by weight of distilled water.

More specifically, the first solution allows easy dispersion and mixing of magnesium chloride and zeolite-based silicate hydrate which realizes the main incombustibility, and can exhibit a certain physical strength when the incombustible liquid is completely cured to be.

That is, the liquefaction of the liquid phase contained in the first solution improves the physical strength of the heat insulating material formed by the incombustible liquid, and when magnesium chloride mixed with the incombustible liquid is heated, Thereby preventing damage to the foamable synthetic resin and splashing out of the filler layer 10.

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.

It is preferable that the liquid phase is contained in the composition in an amount of 1.0 to 3.0% by weight based on the amount of the first solution. If the amount of the liquid phase is less than 1.0% by weight, the physical strength of the heat insulator If the amount of the magnesium chloride exceeds 3.0% by weight, there is a possibility that the resin may accelerate the fire. Therefore, the liquid phase is preferably contained in the first solution at the composition ratio within the range. .

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, And the effect of preventing the damage of the foamable synthetic resin contained in the heat insulating material by the heated magnesium chloride is insufficient. When the content exceeds 33.0 wt%, the above-mentioned effect by the tableted resin is excellent, It is preferable that the refined resin is included in the liquid resin 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.

The heavy chain fatty acid and the dioctyl terephthalate serve as a plasticizer when the heat insulating material is produced by using the incombustible 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 preparing the first solution or the incombustible liquid. However, when the purified fatty acid is mixed into the liquid phase, the plasticity can be improved.

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 heat insulating material that has been completed 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 can also be mixed separately in the preparation of the first solution or the incombustible liquid. However, 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, When the amount exceeds about 3.5% by weight, plasticity is improved. However, since the physical properties of the heat-insulating material are lowered, dioctyl terephthalate is preferably included in the liquid phase in a 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.

The glue is an extract obtained by using leather or bone of an animal as a raw material to improve the physical strength such as tensile strength and compressive strength of the heat insulating material produced in the incombustible liquid as well as 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 wt% with respect to the first solution. When the glue is contained in an amount of less than 1.0 wt%, physical strength such as tensile strength and compressive strength of the heat- The effect becomes insufficient. If the content exceeds 4.0% by weight, the heat-insulating material that has been manufactured may become too 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 incombustible liquid 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 degree of basicity of the produced incombustible fluid is excessively high and the property of the foamable synthetic resin is deformed. Therefore, it is preferable that sodium hydroxide is included in the first solution at a composition ratio within the above 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 incombustible liquid 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 degree of basicity of the produced incombustible fluid is excessively high and the property of the expandable synthetic resin is deformed. Therefore, it is preferable that the tertiary sodium phosphate is included in the first solution at the composition ratio within the range described above.

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%.

Also, the first solution made of the above composition is mixed with distilled water, magnesium chloride and zeolite-based silicate hydrate, and made into a non-combustible liquid.

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 exhibits a certain physical strength when the incombustible liquid is completely cured.

In addition, magnesium chloride is known as a material for realizing incombustibility when it is included in a composition of a heat insulating material, and in the present invention, it is a main composition for realizing incombustibility in addition to a zeolite-based silicate hydrate.

At this time, the salinity of the incombustible fluid varies depending on the composition ratio of magnesium chloride. It is preferable that the incombustible fluid according to the present invention has a salinity of 20 to 30 ‰. That is, if the fire-retardant liquid contains a large amount of magnesium chloride, the incombustibility due to the magnesium chloride is improved. However, due to the excessive magnesium chloride composition, the magnesium chloride is heated during the fire to damage the foamable synthetic resin, Magnesium chloride is preferably contained so that the salinity of the incombustible 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 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, incombustibility due to magnesium chloride is improved. However, if the salt content exceeds 30% by mass There arises a problem that the foamed synthetic resin is damaged by the salt, so that the magnesium chloride preferably maintains the composition ratio within the above range.

In addition, the zeolite-based silicate hydrate contained in the incombustible 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 non-combustible material. In addition, zeolite silicate hydrates have various structures and pore sizes depending on the kind. In the present invention, various types of zeolite silicate hydrates may be used depending on the use of the heat insulating material including the incombustible 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 and the effect of further improving the incombustibility of the incombustible liquid can be obtained.

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 .

At this time, the zeolite-based silicate hydrate having the above-described structure type of faujasite (FAU), chabazite (CHA) or ferrierite (FER) structure is very small in pore size, Even if ignited, the supply of oxygen to the surrounding composition of the zeolite-based silicate hydrate is cut off, thereby exerting an effect of blocking the ignition of the building material.

The zeolite silicate hydrate may have various particle sizes depending on the use of the heat insulating material, but it is preferable to use zeolite silicate hydrate having an average particle diameter of 10 to 400 mu m.

The zeolite 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 liquid. At this time, when the zeolite-based silicate hydrate is mixed in an amount of less than 1 part by weight, the effect of improving the incombustibility with the zeolite-based silicate hydrate becomes 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.

In addition, the fiber yarn, the foamed synthetic resin, and the fire-retardant liquid contained in the filler mixture having the above-described constitution can be appropriately adjusted according to the use of the produced heat insulating material, and preferably the fiber yarn 5 To 15% by weight of the particulate foamable synthetic resin and 85 to 95% by weight of the particulate foamable synthetic resin may be mixed with the fire-retardant liquid.

That is, the filler mixture is composed of 5 to 15% by weight of fiber yarn and 85 to 95% by weight of granular foamable synthetic resin, and the nonflammable liquid is composed of the fiber yarn and the foamed synthetic resin on the incident side, It is possible to make a configuration that is as much as possible.

More specifically, when the filler material is mixed with less than 5% by weight of the fiber material, the composition of the fiber yarn is somewhat insufficient, so that the expandable synthetic resin particles by the fiber yarn may have insufficient effect of strengthening the bond strength and reinforcing the thermal insulation strength. If the content is more than 15% by weight, the composition of the particulate foamable synthetic resin may be insufficient and the heat insulating property of the heat insulating material may be deteriorated. Therefore, the fiber yarn preferably maintains the composition ratio within the above range.

The composition ratio of particulate expanded synthetic resin contained in the filler is preferably 58 to 95% by weight in relation to the composition ratio of the fiber yarn.

The incombustible fluid mixed with the filler having the above composition ratio need not have a specific composition ratio when the filler material is included in the filler mixture in such an amount that the fiber yarn and the foamable synthetic resin particles contained in the filler are sufficiently wetted.

That is, the incombustible liquid contained in the filler mixture is discharged to the outside of the fabric layer 20 by the compression force applied when the fabric layer 20 is formed on the outside of the filler layer 10 (the forming step S200 described below) It is not necessary to include and maintain a specific composition ratio in the filler mixture.

In addition, the filler mixture having the above-described constitution is cured by the hardening of the incombustible liquid to form the filler layer 10, and the fabric layer 20 is bonded to the upper and lower surfaces of the filler layer 10.

At this time, the fabric layer 20 surrounds the outside of the filler mixture before the filler mixture is cured so that the filler mixture maintains a board-like outline, and after the filler mixture is cured, it is disposed outside the heat insulating material As a structure for increasing the strength of the heat insulating material, it may be a nonwoven fabric or a fabric in which a plurality of yarns are woven.

In addition, the fabric layer 20 may be formed in a planar form with the fabric of the above-described type covering the upper and lower surfaces of the filler layer 10, or may be formed in the form of a bag, 10, the lower surface and the side surface.

That is, the fabric layer 20 may be composed of a nonwoven fabric material, and the nonwoven fabric layer 20 may be configured to include a plurality of side surfaces of the filler layer 10.

At this time, the fabric material composed of the nonwoven fabric material as described above may be formed in a bag shape so that the filler material mixture is cured after the filler material mixture is received in the inner space, thereby covering the entire outer portion of the filler material layer 10.

In addition, when the fabric layer 20 is formed of a woven fabric material of nonwoven fabric type as described above, the nonwoven fabric fabric material of the bag form is formed into a board-shaped inner space having a wider form than the side face of the upper and lower faces .

[Manufacturing method of incombustible insulation for building materials]

The present invention relates to a filler mixture preparation for making a filler mixture comprising a filler material and a fire-retardant liquid, wherein the filler material comprises 5 to 15% by weight of at least one fiber yarn of glass wool, cotton yarn or synthetic resin yarn, 85 to 95% Step SlOO; A forming step S200 of placing a fabric material on the upper and lower surfaces of the filler mixture prepared in the filler mixture preparation step S100 and pressing the same to form a fabric layer 20 to form a filler molding; And a drying step (S300) of drying the filling material molded product formed by the molding step (S200), and a method of manufacturing a nonflammable insulating material for building materials.

Specifically, the filler mixture preparation step (S100) may include a filler material and a fire-retardant solution containing 5 to 15% by weight of at least one of fiberglass, cotton or synthetic resin and 85 to 95% by weight of foamed synthetic resin As a process for making a filler mixture to be composed, a specific description of the filler mixture will be substituted with a specific description of the nonflammable insulation material for fragile building materials.

In the forming step S200, a fabric material is placed on the upper and lower surfaces of the filler mixture prepared in the filler mixture preparation step (S100), followed by pressing to form a fabric layer 20 to form a filler molding, Forming a filler layer 10 in a board form using the filler mixture and forming a fabric layer 20 on the upper and lower surfaces of the filler layer 10.

That is, the filling material molding formed in the forming step S200 is formed in the same board shape as the shape of the heat insulating material to be manufactured, the filling material layer 10 having a certain thickness is formed in the filling material molding, And a fabric layer 20 is formed on each of the lower surfaces.

At this time, the fabric material that is seated on the upper and lower surfaces of the mixture of fillers may be formed of a mixture of the foamed synthetic resin particles contained in the filler mixture, which is formed in the form of a board by a constant compression force applied at the upper and lower portions of the filler mixture, So that the incombustible liquid contained in the filler mixture can be discharged to the outside of the filler mixture by the pressing force.

In addition, the compression force applied to the filler mixture in the forming step (S200) can be appropriately adjusted according to the density required for the produced heat insulating material and the thickness of the heat insulating material.

Also, the fabric material of the forming step S200 may be formed of a nonwoven fabric material and may be formed in the form of a bag having an internal space in which the filler mixture is accommodated.

That is, if the fabric material surrounding the exterior of the filler mixture is in the form of a sack, the fabric material is included in the filler mixture squeezed into the board form because it surrounds the entirety of the filler mixture, including the top, bottom and side surfaces of the mixture It is possible to prevent the foamed synthetic resin and the fiber yarn from leaking outward in the forward direction of the filling material molding.

In addition, the drying step (S300) is a process of drying the filling material formed by the molding step (S200), and drying the incombustible liquid contained in the filling material molding to cure the molding material to complete the manufacturing of the heat insulating material.

That is, the amount of the drying heat applied to the filling material molding in the drying step (S300) can be appropriately adjusted according to the kind of the composition contained in the incombustible liquid. As described above, the incombustible liquid is composed of 1.0 to 3.0% A mixture of 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 and 68.0 to 82.0% 1 solution; When the filler material is composed of 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, based on 100 parts by weight of distilled water, It is preferable to dry with the heat of drying.

If the drying temperature in the drying step (S300) is less than 70 ° C, the drying time of the filler material may become excessively long and productivity may deteriorate. If the drying temperature is more than 90 ° C, the rosin and glue contained in the non- It is preferable that the drying heat in the drying step S300 is maintained within the above range because cracking may occur in the filler layer 10. [

Also, when the drying heat is applied at 70 to 90 ° C as described above and the drying step (S300) is performed, the dried filler material may be configured to be dried under a certain pressing force.

That is, as described above, when the filling material molding is subjected to drying heat and is compressed and dried, the fabric layer 20 positioned on the surface of the filling material molding can be more firmly adhered to the filling material layer 10, It is possible to obtain an effect that the flammable liquid discharged out of the fabric layer 20 is discharged to the outside of the fabric layer 20 more quickly and the drying speed of the filling material molding is improved.

However, the pressing force applied to the filling material molding in the drying step (S300) must be smaller than the pressing force applied to the filling material mixture in the molding step (S200), and the pressing force is a direction perpendicular to the upper and lower surfaces of the dried filling material So that the shape of the filler molding having a board shape is not disturbed.
