Description

Thin and Lightweight Composite Board}

The present invention relates to a lightweight composite board, and more specifically, in a state in which lightweight concrete (porous foam concrete or lightweight aggregate mixed concrete) with low mechanical strength due to brittleness that breaks even under a small external force is formed into small, thin blocks. By applying an adhesion promoter and arranging it with a gap, it is reinforced with a polymer mortar binder so that the gap and the surface are integrated. Even when manufactured thinly and widely, the rib stiffener in the gap of the block has higher rigidity than a small block. The surface reinforcement layer on the frame and the surface of the block. (Surface Stiffener) maintains weight reduction, increases mechanical strength (compressive strength, tensile strength, bending strength, etc.) and surface hardness, and provides excellent additional processability (cutting) and constructability (wall fixation) as well as non-combustibility, water repellency, and insulation. and a lightweight composite board for interior and exterior use that has soundproofing performance.

As disclosed in Korea Public Utility Model Publication No. 20-1990-0010217 and FIG. 1A, in general, architectural finishing panels have heat-resistant fibers on at least one of both sides of a flat foam insulation layer (1) made of foamable resin or foamable cement. This is achieved by applying a mesh layer (2) and pressing mortar from its upper surface to form a mortar layer (3) integrally attached to the foam insulation layer (1) with the mesh layer (2) sandwiched in the middle.

In this way, when applying the mesh layer (2) and the mortar layer (3) on the foam insulation layer (1), as shown in FIG. 1B, the mortar layer (3) has the fine particles of the foam insulation layer (1). Very strong bonding is possible by penetrating into the voids, and the mesh layer (2) has the effect of improving bonding strength.

However, unlike lightweight concrete blocks that are cut with a saw to expose the internal porous space, the flat foam insulation layer (1) made of foamed resin is produced to a certain thickness by injection or cutting with a hot wire, so the porous space on the surface is insufficient. As time goes by, the adhesion of the mortar layer (3) decreases or becomes embrittled, causing the mesh layer (2) and mortar layer (3) to separate or break away from the foam insulation layer (1), thereby significantly reducing durability.

In particular, the existing foamed resin constitutes an insulating material attached to the outer wall and has an insulating function as its main function. If it is produced with a thinner thickness, not only does it not have structural rigidity, but its performance as an insulating material is also inevitably reduced by half.

In addition, when the architectural finishing panel consisting of a flat foam insulation layer (1) made of foamable cement is made thin to a large size, the surface hardness, tensile strength, and bending strength decrease, making it difficult to handle, and there is a risk of deformation during the curing process. .

Accordingly, architectural finishing panels composed of a flat insulating layer (1) made of existing foamed cement are produced as thick members of at least 75 mm, usually about 100 mm, and the interior is reinforced with wire mesh to ensure structural stability.

Meanwhile, there is a method of securing structural stability by laminating both sides of the flat foam insulation layer (1) made of foam cement with a separate board of a dissimilar material, but this also has the problem of significantly increasing the total thickness and weight.

Due to problems with adhesion, strength, and displacement with the flat foam insulation layer (1) made of foam cement, there are cases where lightweight concrete is injected into the board on both sides and cured/hardened, rather than laminated. This has the advantage of ensuring structural stability without additional internal reinforcement by using a double-sided board with a certain strength, but it is fundamentally difficult to achieve the goal of a slim panel.

In addition, in order to achieve lightweight production of slim panels, honeycomb cores, which are ribs made of paper, plastic, and steel plates, are used instead of foam insulation layers, and both sides are laminated with thin panels to produce them. , Due to its nature, there was a problem in that sound was not blocked and transmitted due to the hollow layer inside.

Prior Art Document 1: Korea Public Utility Model Publication No. 20-1990-0010217 (1990.06.02)

The present invention was devised to solve the problems of the prior art described above. The purpose of the present invention is to make lightweight concrete with low mechanical strength due to brittleness that breaks even with a small external force into small, thin blocks and to form cracks after applying an adhesion promoter. Even though it is manufactured thin and wide by reinforcing it with a polymer mortar binder so that the gap and the surface are integrated in the arranged state, the rib stiffener in the gap of the block has higher rigidity than a small block. The surface stiffener layer on the frame and the surface of the block. This maintains weight reduction, increases mechanical strength (compressive strength, tensile strength, bending strength, etc.) and surface hardness, and provides excellent additional processability (cutting) and constructability (wall fixation) as well as non-flammable, water-repellent, heat-insulating and sound-proofing properties. The aim is to provide a lightweight composite board.

In order to achieve the above-mentioned purpose, the lightweight composite board according to the present invention is,

In addition, according to the present invention, an adhesion promoter is applied in advance to the surface of the lightweight concrete block and causes a chemical reaction with the cement component of the polymer mortar binder having a cement component, thereby greatly increasing the adhesion between the lightweight concrete block and the polymer mortar binder.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

As shown in Figures 2 to 4, the lightweight composite board 1000 according to the present invention includes a plurality of plate-shaped lightweight concrete blocks 100 arranged with predetermined gaps, the lightweight concrete blocks 100 A polymer mortar binder (300) applied to at least one side of both sides and filled in the gap (110) between neighboring lightweight concrete blocks (100), and a polymer mortar applied to at least one side of the lightweight concrete blocks (100). It is composed of a mesh member 200 that is spread out and disposed on the binder 300, and has a wide plate shape.

Accordingly, the polymer mortar binder 300 hardens in the gap 110 between the lightweight concrete blocks 100 to form a rib stiffener framework 310, and the lightweight concrete blocks 100 The polymer mortar binder (300) hardens on at least one of the two sides of (100) to form a surface reinforcing layer (Surface Stiffener, 320) and is integrated with each other, so that it is not only lightweight but has flame resistance, water repellency, heat insulation, and sound absorption, as well as compressive strength, High mechanical strength and surface hardness, including tensile strength and bending strength, can be obtained.

The lightweight concrete block 100 is made of known porous aerated concrete or lightweight aggregate mixed concrete.

As the main material constituting the lightweight concrete block 100, cement is a representative inorganic material and the most common material capable of exhibiting non-combustible performance, and when mixed with lightweight aggregate, it acts as a binder.

At this time, the porous structure and lightweight aggregate uniformly distributed inside and on the surface of the lightweight concrete block 100 are important elements that not only enable lightweighting, but also provide flame resistance, water repellency, insulation, and sound absorption.

In this way, the lightweight concrete block 100 has various characteristics, but because it is highly brittle, it is easy to break even under a small external force and generally has low mechanical strength.

Figure 5 shows an example of the actual cross-sectional structure of a lightweight concrete block 100, where (a) represents porous aerated concrete and (b) represents lightweight aggregate mixed concrete.

If glass fiber is included in the lightweight concrete block 100, the cracking phenomenon of the lightweight concrete block 100 can be somewhat alleviated.

The table below shows the mixing table of porous aerated concrete and lightweight aggregate mixed concrete, but this is only an example and lightweight concrete blocks with various known mixings can be adopted.

Here, glycerin plays a role in maintaining the bubbles at a certain level, and the high fluidity material plays a role in preventing material separation of EPS grains, allowing the cement mortar to evenly surround the EPS grains to demonstrate flame retardant performance. Vermiculite and Perlite can also be used instead of the EPS.

[Porous foam concrete material]

[Lightweight aggregate mixed concrete material]

The fine porous structure uniformly distributed on the inside and surface of the lightweight concrete block 100 not only allows nails or screws to easily enter, but the porous structure distributed on the surface is similar to that of the polymer mortar binder 300 made of the same material. When filled, adhesive performance improves.

When manufacturing the lightweight composite board 1000 according to the present invention, plate-shaped lightweight concrete blocks 100 having predetermined dimensions in the horizontal and vertical directions are prepared, and are arranged with a predetermined gap between them.

For example, as shown in FIG. 4, as an example, the lightweight concrete block 100 is 50 mm × 50 mm × 10 mm, and the gap 110 between neighboring lightweight concrete blocks 100 is 1 mm. can be formed.

However, the mechanical strength required for lightweight composite boards varies depending on the location and use, such as for interior and exterior use, walls and ceilings, etc., and in order to meet this, the degree of density of the rib stiffener frame portion 310 must be calculated for structural calculation. By determining the size, thickness, shape, and spacing of the gaps 110 of the lightweight concrete block 100, it is possible to respond by inversely determining and arranging them.

The mesh member 200 disposed on at least one of the two sides of the lightweight concrete block 100 is made of glass fiber, cloth, or synthetic resin and serves to resist the tensile force against the polymer mortar binder 300. You can.

The polymer mortar binder 300 is made by mixing a polymer composed of SBR (Styrene Butadiene Rubber), EVA (Ethylene Vinyl Acetate), or Acrylic Emulsion component with cement mortar.

Accordingly, the adhesive performance, waterproofing performance, hardening acceleration, and elasticity properties of the cement mortar are properly exhibited.

In order for the polymer mortar binder 300 to function, 5% to 20% of polymer is mixed by weight in a mortar containing water, cement, and silica sand (SiO2) containing 98% or more of silica with a particle size of 0.3 mm or less. do. At this time, silica sand is better than regular sand as it has no organic impurities and thus helps the mortar strength. When white silica sand and white cement are used, a white-toned polymer mortar binder (300) can be made and is used to produce lightweight composite boards for interior use. It's good to do it.

However, it is understood by those skilled in the art that the above range may be slightly out of proportion depending on the type of polymer.

The polymer used may be an appropriate material depending on the desired properties, such as adhesive performance, waterproofing performance, hardening acceleration, or elasticity.

In this way, when the polymer is mixed with cement mortar, when hardened, it exhibits higher strength and hardness than the lightweight concrete block 100, and a thin surface layer is adhered and hardened with high adhesive force on the porous surface of the lightweight concrete block 100. is formed.

When the polymer mortar binder 300 is applied to the surface of the lightweight concrete block 100, the adhesion strength increases as it fills the porous voids formed on the surface.

Specifically, when the polymer mortar binder 300 is applied to both sides of the lightweight concrete block 100, the polymer mortar binder 300 in the form of slurry hardens on the surface of the lightweight concrete block 100. And some of it naturally flows into the gap 110 between neighboring lightweight concrete blocks 100 and hardens in a state that completely fills the gap 110 between the lightweight concrete blocks 100.

In this way, the polymer mortar binder 300 hardened on the surface of the lightweight concrete block 100 functions to maintain the grip force of fastened nails or screws.

And, as the polymer mortar binder 300 fills the porous voids formed on the opposing sides of the neighboring lightweight concrete blocks 100, the adhesion force is further increased.

If the mesh member 200 is placed and pressed before the polymer mortar binder 300 is hardened, the polymer mortar binder 300 passes through a plurality of holes formed in the mesh member 200 and is hardened with an increased bonding force.

That is, as shown in FIG. 3, when the mesh member 200 is placed and pressed with the polymer mortar binder 300 applied to the surface of the lightweight concrete block 100, the mesh member 200 It is desirable to maintain a slightly impregnated state into the polymer mortar binder 300.

The polymer mortar binder 300 is inserted into the gap 110 between the lightweight concrete blocks 100 and hardens to form a high-strength rib stiffener framework 310, and the lightweight concrete block ( The polymer mortar binder 300 is applied to the upper and lower surfaces of the board 100 together with the mesh member 200 to form a surface reinforcing layer (Surface Stiffener, 320) with greatly increased mechanical strength and surface hardness, and is integrated with each other to form a lightweight composite board 1000. It is completed.

It goes without saying that as the horizontal and vertical sizes of the lightweight concrete block 100 become smaller, the size of the frame portion 310 increases, and thus the mechanical strength increases.

Meanwhile, as shown in FIG. 3, in order to increase the adhesion between the lightweight concrete block 100 and the polymer mortar binder 300, an adhesion promoter 400 is previously applied to the six surfaces of the lightweight concrete block 100. A drying process of approximately 30 minutes is required.

For example, the adhesion promoter 400 may be composed of a polyvinyl acetate homopolymer resin emulsion, which causes a chemical reaction with the polymer mortar binder 300 containing a cement component, thereby further doubling the adhesive strength. It plays a role in increasing mechanical strength.

As shown in FIG. 6, there may be cases where the lightweight concrete block 100 is not hexahedral, and even in this case, the adhesion promoter 400 is applied to all surfaces.

Meanwhile, as shown in FIGS. 3 and 4, reinforcing paper 500 or vinyl is attached to the polymer mortar binder 300 disposed on both sides of the lightweight concrete block 100 to form the lightweight concrete block 100. In addition to protecting the machined surface, it provides structural performance integrally with the polymer mortar binder (300), allowing mechanical strength to be additionally reinforced or becoming a vapor barrier.

In addition, attaching reinforcing paper 500 or vinyl after applying the polymer mortar binder 300 helps curing and hardening the polymer mortar binder 300 and facilitates surface molding of the polymer mortar binder 300.

In this way, according to the present invention, the porous lightweight concrete block 100 is arranged with gaps 110 at regular intervals and can absorb fine cracks while exhibiting higher strength and hardness than the lightweight concrete block 100. The gap 110 and the surface are filled and applied with a polymer mortar binder 300 having a certain elasticity (elastomeric).

As a result, after the polymer mortar binder 300 is cured, the rib stiffener frame portion 310 with high mechanical strength and mechanical strength and surface hardness are formed in the gap 110 between the lightweight concrete blocks 100. The increased surface reinforcing layer (Surface Stiffener, 320) is integrated with each other to form a structural shape that resists compressive, tensile, and bending forces, and the surface reinforcing layer (Surface Stiffener, 320) provides water repellent performance and nail grip. There will be.

In addition, the large flat foam insulation layer 1 made of conventional foamable resin or foamable cement must be disposed of as a whole when a part of it is broken or damaged during the manufacturing process, but the thin plate-shaped lightweight concrete block 100 can be cut. This not only has the advantage of being able to replace parts during the manufacturing process, but also makes work and handling much more convenient.

In addition, the polymer mortar binder 300 is tightly filled and hardened in the fine porous structure distributed on the surface and the gap 110 of the lightweight concrete block 100 to form the rib stiffener framework 310 and the surface reinforcement layer. (Surface Stiffener, 320) primarily improves the surface adhesion of the lightweight concrete block 100, and additionally adds an adhesion promoter (polyvinyl acetate homopolymer resinous emulsion) to the porous surface of the lightweight concrete block 100. 400) is applied to secondarily double the adhesive strength through a chemical reaction with the cement component of the polymer mortar binder 300, thereby causing separation from the lightweight concrete block 100 or separation of the lightweight concrete blocks 100 from each other due to external force. can be prevented.

In addition, it is possible to maintain high flame retardancy (non-combustibility) by the cement component that constitutes the lightweight concrete block 100 and the polymer mortar binder 300.

In addition, the size, thickness, and arrangement of the unit lightweight concrete block 100 are varied according to the degree of compressive strength, tensile strength, and bending strength required, so that the total area occupied by the rib stiffener frame portion 310 per unit area is calculated. Structural performance can be adjusted by adjusting or structuring the layers into multiple layers. At this time, the thicker the thickness, the larger the size can be, and if the area occupied by the rib stiffener frame portion 310 is sufficiently large, the mesh member 200 and reinforcing paper 500 or vinyl can be omitted. The larger the gap between the gaps 110, the higher the mechanical strength.

Meanwhile, as another embodiment, as shown in FIG. 7, color steel plates 600 are laminated on one side of the lightweight concrete block 100, and the above-described mesh member 200, polymer mortar binder 300, and Reinforcement paper 500 or vinyl may be placed.

The mesh member 200 and reinforcing paper 500 or vinyl on the side where the color steel plate 600 is disposed may be omitted.

The color steel plate 600 is configured to surround the peripheral surface of the lightweight concrete block 100.

In this case, the back side of the color steel plate 600, which is bent by a press at once without cutting the edge of the color steel plate 600, is placed on a workbench with the upper surface, and a polymer mortar binder 300 is applied to form a lightweight concrete block 100. ), when laminated by pressing, the polymer mortar does not overflow over the bending jaw or leak out of the edge cut surface, and after installation on the wall is completed, the edge cut surface is not visible through the gap in the plaster, making it possible to use a color steel composite board with a smooth mortar. do. At this time, when the adhesion promoter 400 is applied to the back of the colored steel plate 600 and laminated with the polymer mortar binder 300 side, the adhesion can be improved in the same way as when applied to the lightweight concrete block 100.

As another embodiment, as shown in Figure 8, the task of creating a fastening groove with an inclined surface on a removable composite board is difficult because it requires accurate positioning of the fastening groove on a large flat panel and precision machining with CNC, but small block It can be produced by placing a small block of the lightweight concrete block 100 at a position where a fastening groove is required in a placement jig with a fixed rigid block 700 in which the fastening groove slot 710 is pre-machined.

That is, the structure is such that the fixed rigid block 700 is disposed with a gap between any two lightweight concrete blocks 100, and the material is such that the shape of the fastening groove slot 710 is not damaged. Cement board is good because it is rigid and has non-combustible properties.

In this case, the lightweight composite board 1000 according to the present invention has the characteristics that the position of the fastening groove in the jig can be very easily held without error just by placing it in the jig, and the wall and ceiling fixing means 720 can be fixed by sliding fastening. there is.

That is, half of the wall and ceiling fixing means 720 is inserted into the fastening groove slot 710 formed in the lightweight composite board 1000, and the remaining half is fixed to the steel or wooden frame of the wall or ceiling. (1000) can be fixed to the wall or ceiling without exposing screws, and can automatically form a flat surface with the neighboring lightweight composite board (1000), ultimately enabling easy and accurate attachment and detachment of the lightweight composite board (1000). This becomes possible.

(6) After the polymer mortar binder 300 is entirely applied on the mesh member 200, a jig for placing small blocks is placed on it.

(7) In the jig, small blocks are placed at predetermined intervals so that the polymer mortar binder 300 faces each other on the mesh member 200.

(8) The small blocks are compressed so that the polymer mortar binder 300, the mesh member 200, the reinforcing paper 500, and the vinyl or colored steel sheet 600 are stacked in a compressed state on the lower surface of the small block.
