Description

Building interlayer structure using insulation panel {STRUCTURE FOR INTER LAYERS OF BUILDING USING HEAT INSULATING PANEL}

The present invention relates to an insulating panel having insulation, non-combustible, sound-absorbing, sound insulation and cushioning effect and the interlayer structure of the building using the same. More particularly, the present invention relates to an insulation panel manufactured by using an inorganic binder, a porous mineral material, a fibrous material, an organic binder, and water, and an interlayer structure of a building constructed using the insulation panel.

In the construction of a multi-layered building, various methods are being installed on the concrete floor for insulation and sound insulation of floors and floors.

First, there is a method of applying the mortar on the concrete floor to harden, install the pipes, and then clean up the floor with a finishing material, but this does not only harmfully affect the human body due to the toxicity of cement, but also does not effectively block interlayer noise.

In addition, there is a method of laying a shock-absorbing pad, such as rubber on the concrete floor and placing foam concrete on it, and re-installing mortar, but this has a problem in that the construction is complicated and time-consuming and expensive.

In addition, there are methods to harden the cement and install elastic mats on the concrete floor through various steps such as placing gravel or tire powder on the concrete floor and placing cement on it. There was a lot of trouble.

Therefore, the inventors of the present invention devised a careful study, as well as the sound insulation and sound absorption as well as the insulation and non-combustible and developed a heat insulation panel excellent shock impact ability.

Insulation panel of the present invention can be used as a floor insulation of the building, as well as a sandwich panel core material or wall side insulation insulation constituting the interior wall and can also be used as a ceiling material.

In addition, the thermal insulation panel of the present invention can be used in addition to the building construction, for example, can be used in the inner and outer core material of the subway vehicle, fire door core material, large heavy equipment, thermal insulation of pipes and the like.

In particular, the thermal insulation panel of the present invention can shorten the air by using a dry method produced by the panel or a solid of a certain shape, away from the conventional wet construction method, the site is clean, easy to install and economical.

It is an object of the present invention to provide a thermal insulation panel having a cushioning effect as well as heat insulation, sound absorption, sound insulation, non-combustible.

Another object of the present invention is to provide an interlayer structure of a building that cushions sound insulation and shock, which is constructed in a building using the insulating panel of the present invention.

In addition, the present invention is to provide a dry insulation panel to facilitate the construction and shorten the air in the building construction to reduce costs as well as to recycle waste resources to prevent environmental pollution.

Hereinafter, the heat insulation panel of this invention is demonstrated in detail.

Insulation panel of the present invention is characterized in that it comprises an inorganic binder 35 to 60% by weight, porous minerals 0.5 to 15.0% by weight, fibrous material 0.1 to 15.0% by weight, organic binder 0.1 to 5.0% by weight and the balance.

In the heat insulation panel of the present invention, the inorganic binder is preferably used as gypsum to function to combine the components constituting the heat insulation panel. Gypsum combines the components tightly and blocks the air, thus providing a non-flammable / flame retardant effect in case of fire. However, the inorganic binder is not limited to gypsum alone, and all commercially available inorganic binders such as water glass may be used.

Gypsum used in the present invention may be used, such as natural gypsum or waste gypsum. Waste gypsum is a condition of completed gypsum generated from sludge from a fertilizer plant or power plant, and can be recycled to semi-mineral gypsum or anhydrous gypsum using conventional facilities such as rotary kiln.

The inorganic binder is preferably contained 35 to 60% by weight relative to 100% by weight of the composition. When the content of the inorganic binder is less than 35% by weight, there is a disadvantage that the bonding strength is not sufficient, and when the content of the inorganic binder exceeds 60% by weight, it is heavy.

In the thermal insulation panel of the present invention, the porous mineral material absorbs and disperses noise and impact due to a number of pores included in itself, and serves to increase sound insulation and cushioning as well as sound insulation and cushioning. Porous minerals used in the present invention may be selected from tuff, volcanic rock, pumice, pumice, perlite, elvan, vermiculite or two or more thereof. However, the porous mineral is not limited to the above-mentioned minerals, and other known porous minerals or porous minerals that may be newly discovered and developed may be used in place of the minerals.

The porous mineral is preferably contained 0.5 to 15% by weight relative to 100% by weight of the composition. When the porous mineral is less than 0.5% by weight, there is a disadvantage in that noise and impact reduction effect is reduced, and wetting and heat insulation are lowered. When it is more than 15% by weight, the content of other components, particularly inorganic binders and organic binders, is reduced, thereby lowering the bonding strength. There is a problem that the workability is reduced.

In the present invention, the average particle diameter of the porous mineral material is preferably 1 to 10 mm.

In the thermal insulation panel of the present invention, the fibrous material reinforces the strength of the thermal insulation panel and maintains the structure of the thermal insulation panel product of the present invention. That is, the insulation panel itself forms a network structure to prevent a weighty component such as gypsum from settling down when each component is mixed to form a uniform structure as a whole. The fibrous material which is preferably used in the present invention is pulp or common paper which loses crosslinkability by the blended water.

Pulp is a collection of cellulose fibers mixed with a fine solid and liquid extracted from plants such as wood may be used natural pulp or recycled pulp. In addition, conventional paper may be used as the paper, paper mill, waste paper mill, waste paper dispersed in water or paper sludge from the paper production process in the paper mill, etc. can be used. In particular, the paper is lightweight and excellent in heat insulation, and in particular, increases the binding strength of the solidified components and improves the impact resistance.

When the content of the fibrous material is less than 0.1% by weight, the effect of improving the horizontal drag and impact resistance of the insulation panel product of the present invention may not be sufficient. When the content of the fibrous material exceeds 15% by weight, other components, particularly inorganic binders and organic binders, etc. There may be a problem of reducing the mechanical properties and reducing the workability by reducing the content.

In the thermal insulation panel of the present invention, the organic binder functions to combine the components constituting the thermal insulation panel, improve mechanical properties and increase water tightness. In addition, the organic binder strengthens the viscosity of the insulation panel and keeps the bubbles without breaking when bubbles are generated in the insulation panel. In particular, when the gypsum is added, bubbles are easily broken, and the organic binder combines the components without destroying the bubbles.

Organic binders preferably used in the present invention are aqueous acrylic, ethyl vinyl acetate or polyvinyl alcohol and the like. In the present invention, the organic binder is not limited to the above, and other commercially available binders and adhesives having a bonding function may be used, including other aqueous organic binders having elasticity.

In the present invention, when the content of the organic binder is less than 0.1% by weight, the bonding strength is weak, so that the rigidity is weak, and when the content exceeds 5.0% by weight, there is a disadvantage that is not economical without a special improvement effect.

The amount of the blending water used in the thermal insulation panel of the present invention is an amount in which the inorganic binder, the porous mineral material, the fibrous material, and the organic binder are mixed in a proportion and filled with the remainder with respect to 100% by weight of the composition. This may be defined as an amount sufficient to dissolve the organic binder sufficiently and to be mixed with the solid mixture and the like to have a viscosity that can be poured like a conventional slurry.

In the thermal insulation panel of the present invention, a foaming agent may be further included in an amount of 0.1 to 3.0 wt% based on 100 wt% of the composition. Foaming agent makes bubbles in the insulation panel to lighten the product and have the effect of insulation, sound insulation, cushioning and the like.

Foaming agents which are preferably used in the present invention are vegetable foaming agents. However, the present invention is not limited to vegetable foaming agents, and animal foaming agents can also be used.

When the content of the foaming agent is less than 0.1% by weight, there is a disadvantage in that the generation of bubbles is not sufficient, and when the content of the foaming agent exceeds 3.0% by weight, there is a problem in that the strength is weakened due to the excessive generation of bubbles.

In the thermal insulation panel of the present invention, silica may be further included in an amount of 0.1 to 5.0 wt% based on 100 wt% of the composition. Silica not only strengthens the strength but also acts as a desiccant or dehydrating agent to accelerate the curing and drying of the present insulation panel products.

When the content of the silica is less than 0.1% by weight, there is a disadvantage in that the fast curing and drying effect by the silica is insignificant, and when the content of the silica is more than 5.0% by weight, there is a problem in that the economical difference is not large.

In the thermal insulation panel of the present invention, the foam may be further included 0.1 to 5.0% by weight based on 100% by weight of the composition.

The foam is lightweight and has excellent thermal insulation and shock absorption, and functions as a thermal insulation and a buffering effect in the thermal insulation panel of the present invention. Preferably, the foam used in the present invention is selected from the group consisting of styrofoam, urethane foam and rubber. However, the foam in the present invention is not limited thereto, and any kind of foam having artificial porosity and elasticity may be used. It is preferable that the foam has an average diameter of 10 mm or less.

In particular, in the present invention it is possible to use the foam of the waste material waste styrofoam or waste urethane foam can be used. That is, spherical styrofoam foams, waste tires, shoe soles, etc. remaining after being foamed in a styrofoam manufacturing plant and molded into a plate may be used.

When the content of the foam is less than 0.1% by weight, there is a disadvantage that the insulation and buffering effect by the foam is inadequate, and when the content of the foam exceeds 5.0% by weight, the strength is weakened.

In the thermal insulation panel of the present invention, cement may be further included 1.0 to 15.0% by weight based on 100% by weight of the composition. In addition, lime may be used instead of cement, and further, cement and lime may be further included in an appropriate ratio.

Cement is a material commonly used to mix with water in building construction to form walls and floors, and is relatively inexpensive and easy to place. In the present invention, a certain amount of cement may be further included to enhance the strength of the insulation panel. The cement is generally used portland cement, but other cements such as alumina cement may be used.

In the heat insulation panel of the present invention, when the content of cement or lime is less than 1.0% by weight, there is a problem in that the strength enhancement effect by cement or lime is insignificant and the weight becomes heavy when it exceeds 15% by weight.

In the thermal insulation panel of the present invention, a waterproofing agent may be further included in an amount of 0.2 to 1.0 wt% based on 100 wt% of the composition.

Waterproofing agent is used to prevent the absorption of moisture in the thermal insulation panel product of the present invention can be purchased and used commercially supplied to those skilled in the art. For example, as a mixed agent of mortar and concrete, there exists a waterproofing agent which increases waterproofness and watertightness. This waterproofing agent creates a hydrophobic coating in the fine pores in mortar or concrete, thereby exhibiting a waterproofing effect.

When the waterproofing agent is included in less than 0.2% by weight, the waterproofing effect is inadequate and when included in excess of 1.0% by weight, there is a disadvantage in that workability is insignificant without significant difference in effect.

In the heat insulation panel of the present invention, glass fiber may be further included in an amount of 0.1 to 0.5 wt% based on 100 wt% of the composition.

Glass fiber is a mineral fiber made of molten glass in the form of fibers. The fiber is about 5 mu m thick and about 2 to 12 mm long. It is resistant to high temperatures and does not burn well. In addition, it has strong tensile strength and low elongation rate, and is mainly used as insulation, insulation, and sound-absorbing sound insulation material in building relations. In the thermal insulation panel of the present invention, the glass fiber serves to enhance the bending strength of the product to be manufactured.

When the glass fiber is included in the thermal insulation panel of the present invention less than 0.1% by weight, the strength effect by the glass fiber is insufficient, and when included in excess of 0.5% by weight, the strength may be too high and may be easily broken. have.

In the thermal insulation panel of the present invention, when the glass fiber is added, the humectant may be further included in an amount of 0.2 to 1.0 wt% based on 100 wt% of the composition.

A humectant acts as a binder, tangling the glass fibers with each other, thereby strengthening the bond and strengthening the strength. It is to be understood that the humectants used in the present invention are commercially supplied to those skilled in the art.

When the moistening agent described above is included in the insulation panel of less than 0.2% by weight, the bonding strength is low, and when the moiety is included in an amount exceeding 1.0% by weight, the strength is too high.

On the other hand, the thermal insulation panel of the present invention is 35 to 60% by weight inorganic binder, 0.5 to 15.0% by weight porous mineral material, 0.1 to 15.0% by weight fibrous material, 0.1 to 5.0% by weight organic binder, 0.1 to 3.0% by weight foaming agent, 0.1 to silica It is preferred to comprise 5.0% by weight, 0.1 to 5.0% by weight of foam and the balance of the blended water.

At this time, cement, lime or a mixture thereof may be further included 1.0 to 15.0% by weight based on 100% by weight of the composition for heat insulating material.

In addition, the waterproofing agent may be made to further include 0.2 to 1.0% by weight based on 100% by weight of the composition for heat insulating material.

In addition, the glass fiber may be made to further comprise 0.1 to 0.5% by weight based on 100% by weight of the composition for heat insulating material.

When glass fibers are used, the wetting agent may be further included in an amount of 0.2 to 1.0 wt% based on 100 wt% of the composition for thermal insulation.

The heat insulation panel of this invention is used in mixture in an appropriate ratio within the composition ratio of the above-mentioned component.
