Description

Composite insulation and its manufacturing method {COMPLEX INSULATION MATERIAL AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a composite insulation material and a method for manufacturing the same.

In general, the exterior insulation method of a building is to prevent heat transfer by placing an insulating layer on the exterior wall of the building.There are many advantages in terms of energy saving compared to the internal insulation method installed inside the existing building, and the distribution is gradually expanding. .

However, with the strengthening of energy saving standards, the thickness of the insulating layer is increasing, and most of the materials used are organic insulating materials, mainly polystyrene foam. In addition, an organic insulating material is used to insulate the outer wall or the finishing material of a dry finishing method such as a stone panel or a metal panel, or a composite panel laminated with a polyethylene resin inside the metal panel is used.

As described above, the organic insulation used for the insulation layer (exterior insulation) of the exterior wall of the building is vulnerable to fire. In this case, there was a fatal problem of rapidly spreading as the fire was easily transferred to the organic insulating material used in the insulating layer and used as a propagation path for the fire.

On the other hand, there is an attempt to easily apply an inorganic material instead of an organic material as an external insulating material, but in the case of an inorganic material, it has excellent fire resistance, but has poor thermal insulation properties, and also adjusts tensile strength, weight, or thickness to meet the external insulation standard. There was a difficult problem, and the use was limited because the price was high.

In particular, hospitals, nursing homes, and children's facilities are more vulnerable to fire, so more measures are needed to effectively suppress the rapid spread of fire.

The present invention has been devised to solve the above-mentioned problems, and at least a portion of the organic board includes an inorganic block; And an inorganic board that is bonded to one surface of the organic board and includes an organic block in which at least some areas are bonded to one surface of the inorganic block, thereby providing a composite heat insulating material having excellent heat insulation and effectively blocking diffusion of fire. Let's try to solve the problem.

In order to solve the above problems, according to an aspect of the present invention, the organic board having a first thickness, at least a portion of the region includes an inorganic block, the inorganic block is a plurality of layers stacked according to the thickness direction; And an organic block that is bonded to one surface of the organic board and at least a portion of the area is bonded to one surface of the inorganic block, and has a second thickness and an inorganic board having a plurality of layers stacked along the thickness direction. Insulation is provided.

As described above, the composite insulating material related to at least one embodiment of the present invention is composed of an organic board including an inorganic block and an inorganic board including an organic block, as the inorganic block and the organic block are bonded, fire resistance and It has the advantage of excellent fire safety.

The composite insulating material includes an organic board 100 and an inorganic board 200.

The organic board 100 has a first thickness, and at least a part of the region includes the inorganic block 200a, but the inorganic block 200a has a plurality of layers stacked according to the thickness direction. The organic board 100 is disposed to be adjacent to the outer wall (base surface, 10) of the building during the external insulation construction. The composite insulation material according to the present application may be adhered and fixed to the outer wall 10 of the building via the organic board 100.

In the case of the organic board 100, since it is arranged to be adjacent to the outer wall of the building, it is important to realize excellent thermal insulation properties. Therefore, the material of the organic board 100 is not particularly limited, as long as it is excellent in thermal insulation. For example, the organic board 100 includes a foamed foam, and the foamed foam may include polystyrene, polypropylene, ethylene, polyvinyl acetate polyurethane, polyisocyanate, and phenol, but has processability, cost, and thermal insulation properties. In consideration, it may include a foamed phenolic foam (PF-Board), preferably comprising phenol.

The inorganic board 200 includes an organic block 100a that is bonded to one surface of the organic board 100 and at least a portion of the area is bonded to one surface of the inorganic block 200a, and has a second thickness and thickness. A plurality of layers are stacked along the direction. In general, the inorganic board 200 is excellent in fire resistance and fire stability, but it is difficult to manufacture in a standard suitable for external insulation construction because it is limited to manufacturing in light weight and slim type. Therefore, in the case of the inorganic board 200 suitable for external insulation construction, it is important to be excellent in fire resistance, fire stability, compressive strength and tensile strength, and at the same time, to be manufactured in a lightweight and slim type, which is a material selection of the inorganic board 200 and It can be achieved by controlling the properties. Details of this will be described later.

Since the organic block 100a and the inorganic block 200a are included in at least some regions of the inorganic board 200 and the organic board 100, respectively, they serve as safety devices that effectively block flame propagation in the event of a fire. In general, since the organic board 100 is excellent in heat insulation but is vulnerable to heat, there is a problem in that flame is propagated by the organic board 100 when a fire occurs, but the organic board 100 according to the present application has at least some areas By including the inorganic block 200a, the flame propagating through the organic board 100 can be expected to have an effect that the inorganic block 200a is blocked and thus no longer propagates.

The organic block 100a and the inorganic block 200a may be included in the organic board 100 and the inorganic board 200 by reverse construction during external insulation construction, respectively. The composite insulation material according to the present application is constructed and arranged in the order of the outer wall (base surface), adhesive mortar, organic board 100, and inorganic board 200 of the building during external insulation construction. In at least some areas, the outer wall of the building, adhesive mortar , As the arrangement order of the inorganic board 200 and the organic board 100 is reversed in the order of the inorganic board 200 and the organic board 100, at least some areas of the organic board 100 and the inorganic board 200 are respectively The inorganic block 200a and the organic block 100a may be included. In other words, in the inorganic block 200a, a part of the inorganic board 200 is included in the organic board 100, and in the organic block 100a, a part of the organic board 100 is included in the inorganic block 200a. You can. Therefore, the inorganic block 200a has the same material as the inorganic board 200, and the same physical properties can be implemented, and the organic block 100a has the same material as the organic board 100 and the same physical properties can be implemented. have. Therefore, the organic block 100a and the organic board 100; And the thickness of the inorganic block 200a and the inorganic board 200 may be the same as each other, for example, the organic block 100a may have a first thickness, and the inorganic block 200a may have a second thickness. .

In order to simultaneously achieve excellent thermal insulation and fire resistance of the composite insulation, the size of the region including the organic block 100a and the inorganic block 200a must be adjusted within an appropriate range. The scale of the size may be expressed as a ratio of the length between the board and the block, which will be described later.

In one example, the organic board 100 (and / or the inorganic board 200) has a first length L ₁ , and the inorganic block 200a (and / or the organic block 100a) is a second length. (L ₂ ), the ratio of the first length and the second length (L ₁ / L ₂ ) may be 1: 1 to 1: 3.

As described above, the inorganic board 200 is excellent in fire resistance, fire stability, compressive strength, and tensile strength, and at the same time, it is important to be made of a lightweight and slim type, which can be achieved by forming a specific structure in the inorganic board 200 You can. Hereinafter, the specific structure will be described in detail. In addition, the following specific structure may also be implemented in the inorganic block 200a.

The inorganic board 200 having the specific structure is a cross-section along the thickness direction of the inorganic board 200, and at least one layer 201 connects the organic board 100 and the bonding line 101 of the inorganic board 200. Accordingly, it has a plurality of maximum points (A) and minimum points (B) appearing consecutively.

Specifically, the inorganic board 200 includes: a first region 210 in which a thickness direction interval between adjacent maximum points A ₁ and minimum points B _{1 in} at least one layer 201 is 0.5 cm or more; And the sum of the number of the maximum points (A ₂ , A ₃ ..) and the smallest points (B ₂ , B ₃ ..) of at least one layer 201 in the cross section made of 5 cm × 5 cm among the cross sections along the thickness direction is 4 A second or more second region 220; It may include at least one region. In the present application, a plurality of maximum points are indicated in the order of A1, A2, A3 ?, and a plurality of minimum points are shown in order of B1, B2, B3 .., and when the maximum and minimum points are collectively indicated as A and B, respectively. I will write it down.

More specifically, the inorganic board 200 may have a predetermined length (l), width (w), and thickness (t). In the above, the term "cross-section of the inorganic board 200 in the thickness direction" refers to C3 axis (orthogonal to the thickness direction (x) and the longitudinal direction (z), respectively), C2 axis (thickness direction (x) and It includes all cross sections cut in the width direction (w orthogonal to each) and C1 or C2 axis with respect to any axis having a predetermined angle. In addition, in the thickness direction cross section of the inorganic board 200, in FIG. 3, any cross section parallel to the y-z plane is not included. In this case, the above-described first region 210 and / or second region 220 may not appear when cutting with respect to a specific axis. For example, in FIG. 3, the first region 210 and / or the second region 220 described above appears at any cross section parallel to the xy plane, and the first region described above at any cross section parallel to the xz plane. The region 210 and / or the second region 220 may not appear.

The maximum point (A) and the minimum point (B) will be described in more detail with reference to FIG. 4. The at least one layer 201 has a wave shape along the junction line 101, and has an alternately convex upward and downward convex shape. At this time, the convex upward shape corresponds to a region in which the thickness direction spacing t ₁ increases and decreases from the bonding line 101, and the downward convex shape has a thickness direction spacing t ₂ from the bonding line 101. It corresponds to an area that decreases and then increases. At this time, the maximum point (A), in one upward convex shape, the thickness direction interval t ₁ represents the maximum value, and the minimum point (B) is one downward convex shape in the thickness direction interval (t ₂ ) This represents the minimum value. Accordingly, the at least one layer 201 has a shape in which convex upward and convex downward are continuously altered along the junction line 101, and a plurality of maximum points (A) and minimum points along the junction line 101. (B).

The distance X in the thickness direction of the first region 210 may be, for example, 0.5 cm or more, 1 cm or more, or 1.5 cm or more. In addition, the upper limit of the gap (X) may be 5 cm or less, 4 cm or less, or 3 cm or less. Specifically, the interval (X) is 0.5cm to 5cm, 1cm to 5cm, 1.5cm to 5cm, 0.5cm to 4cm, 1cm to 4cm, 1.5cm to 4cm, 1.5cm to 3cm, 1cm to 3cm or 1.5cm to 3cm It can be within range. In addition, the upper limit of the number of the second regions 220 may be 25 or less, 20 or less, 15 or less, 10 or less, 9 or less, 8 or less, or 7 or less, for example, The sum of the numbers may range from 4 to 25.

Since the inorganic board 200 includes at least one of the first and second regions 210 and 220, excellent compressive strength and tensile strength are realized. Adjustment of the distance between the lowest and highest points of the first region 210 and the number of the highest points (A) and lowest points (B) of the second region 220 may be achieved by a crimping process described below.

On the other hand, in order to include any one of the first region 210 and the second region 220, it is also important to select the material of the inorganic board 200. For example, the inorganic board 200 may include a modified glass wool or a modified mineral wool, and preferably may include a modified mineral wool.

In general, in the case of a known mineral wool, in general, in the case of a known mineral wool, the thickness (X) in the thickness direction of the aforementioned first region 210 is 0.5 cm or less, or the second The total number of regions 220 is less than four. In the case of these known mineral wools, it is difficult to adjust the density within the above-mentioned range, which suggests that the control of compressive strength, tensile strength and thickness suitable for external insulation construction is limited. On the other hand, the modified mineral wool is crimped, and the sum of the number of the distances X and the second regions 220 in the thickness direction in the first region 210 satisfies the aforementioned range. Therefore, in the case of a modified mineral wool, it has an improved density compared to a known mineral wool, and thus has an advantage of easy control of compressive strength, tensile strength and thickness suitable for external insulation construction.

In one example, the composite insulation may further include an adhesive layer bonding the organic board 100 and the inorganic board 200. The thickness of the adhesive layer may be 0.1 cm to 2 cm, 0.5 cm to 2 cm or 1 cm to 2 cm.

The composite insulation material may adjust the thickness and density of the organic board 100 and the inorganic board 200 within the following numerical ranges, thereby realizing properties required for external insulation.

In one example, the first thickness of the organic board 100 may be 50 mm to 200 mm, 80 mm to 170 mm or 100 mm to 130 mm. In addition, the second thickness of the inorganic board 200 may be 50 mm to 200 mm, 80 mm to 170 mm or 100 mm to 130 mm. In the composite insulation material, the density and thermal conductivity of the composite insulation material may be adjusted to be lower as the thickness of the organic board 100 becomes thicker or the thickness of the inorganic board 200 becomes thin within the above range.

In addition, ignition and carbonization of the organic board 100 may be effectively suppressed according to the thickness of the inorganic board 200. For example, when the thickness of the inorganic board 200 is 60 mm or more, ignition of the organic board 100 is effectively suppressed, and when it is 70 mm or more, carbonization of the organic board 100 can be effectively suppressed.

In one example, the density of the organic board 100 is 10 kg / m ³ to 110 kg / m ³ , 15 kg / m ³ to 100 kg / m ³ , or 20 kg / m ³ to 80 kg / m ³ , and the density of the inorganic board 200 may be 100 kg / m ³ to ^{300kg / m 3, 120 kg /} m 3 to 250kg / m ^3, or 130 kg / m ³ to 200kg / m ³ days. In the case of the inorganic board 200 that satisfies the density within the above numerical range, as excellent compressive strength and tensile strength are realized at a thin thickness, it is applicable to external insulation construction.

In one example, the composite insulation may include a non-combustible coat layer 300 and a reinforcing mesh 400.

The non-combustible coat layer 300 is provided on the other surface of the inorganic board 200 that is not bonded to the organic board 100. In the above, the term "another surface of the inorganic board" means one surface of the inorganic board 200 that is not bonded to the organic board 100. The non-combustible coat layer 300 serves to prevent deformation of the insulating material, crack prevention, external shock and fire diffusion.

In one example, as long as the non-combustible coat layer 300 satisfies the KSF ISO 1182 flame retardancy test specification, the material is not particularly limited, for example, cement, silica (SiO ₂ ), titanium dioxide (TiO ₂₎ ) Limestone, dolomite, and fine metal particles. When constructing the outer insulation of the composite insulation material, the non-combustible coat layer 300 may be manufactured through the application and curing steps of the mixture.

In addition, the thickness of the non-combustible coat layer 300 may be in the range of 1 mm to 30 mm, 1 mm to 25 mm, or 2 mm to 20 mm.

The reinforcing mesh 400 is embedded in the non-combustible coat layer 300. The material of the reinforcing mesh can be glass fiber. The durability of the reinforcing mesh 400 satisfies the specification conditions according to the impact strength 10J test and alkali ASTM E2098 test. When the reinforcing mesh 400 is buried, it means that it is cured after being applied (or laminated) in the order of the non-combustible coat layer 300 / reinforcement mesh 400 / non-combustible coat layer 300 when the outer heat insulation is applied to the composite insulation material. do. In this case, the sum of the thicknesses of the two non-combustible coat layers 300 stacked on both sides of the reinforcing mesh 400 may range from 1 mm to 30 mm, 1 mm to 25 mm, or 2 mm to 20 mm. The reinforcing mesh 400 serves to prevent loss of insulation due to strength reinforcement and wall damage.

In order to reinforce the strength of the composite insulation, the unit mass per area of the reinforcing mesh 400 should be adjusted within an appropriate range, for example, the reinforcing mesh 400 is 50 g / m ² to 300 g / m ² , 80 g / m ^It may have a unit mass per area in the range of ² to 250 g / m ² or 100 g / m ² to 200 g / m ² .

In one embodiment, a plurality of fasteners 500 for fixing may be additionally installed on the other surface of the inorganic board 200. The fastener 500 is installed on the other side of the inorganic board 200 to fix the insulating material on the outer wall (reinforced concrete, etc.) of the building, or serves to reinforce the adhesive strength. The inorganic board 200 has improved adhesion strength due to excellent tensile strength, and thus a minimum fixing fastener 500 can be installed, and thus an effect of reducing construction cost can be expected. For example, in the case of attaching a composite insulating material to the outer wall of a building with wet mortar and fixing it with a fastener for fixing, sufficient fixing effect can be expected even if 1 to 2 fasteners per unit area (m ² ) are used. You can.

The composite insulation material of the present application may be applied with a dry construction method during external insulation construction, and in this case, the composite insulation material includes a reinforcement frame 600, a connection frame, and an exterior board 700.

The reinforcing frame 600 serves to bond the exterior board 700 to the composite insulation material according to the dry method. The reinforcing frame 600 may have a mesh structure in which the reinforcing frames 600 are spaced apart from the non-combustible coat layer 300 at predetermined intervals, and a plurality of horizontal frames and vertical frames are connected. The spacing is in accordance with the standard specification of the dry method, for example, may be in the range of 10mm to 200mm, 20mm to 150mm or 30mm to 100mm.

The plurality of connection frames may connect the reinforcement frame 600 and the non-combustible coat layer 300. The plurality of connection frames connect both sides of the reinforcing frame 600 and the non-combustible coat layer 300, and each connection frame may be disposed spaced apart at predetermined intervals. For example, the plurality of connection frames may be formed to extend from the horizontal frame of the reinforcement frame 600. The connection frame may be formed of the same material as the reinforcement frame 600, for example, may be formed of a material having excellent mechanical strength, such as steel.

The exterior board 700 serves as a finishing material and may be joined to the reinforcement frame 600. The exterior board 700 may be applied to the reinforcement frame 600 and dried to be bonded to the reinforcement frame 600. For example, the exterior board 700 is a Cellulose Fiber Reinforced Cement Board. , CRC board) or wood cement board (Cemented Excelsior Borard), but is not limited thereto, and a known finishing material may be used as the external board 700. For example, the exterior board 700 is a cement board, a board made of a metal material (for example, a metal panel, an aluminum composite panel, a color steel sheet (galvalume), a zinc panel), a siding, a sandwich panel, artificial marble, tile or brick Can be
