Description

Composite panel using paraboard and bubble aluminum}

The present invention relates to a composite panel using paraboard and foamed aluminum, and more particularly, to a composite panel using paraboard and foamed aluminum incorporating a paraboard made by mixing a foamed aluminum, which is a porous structure, and expanded pearlite with an inorganic binder. It is about.

In general, foamed aluminum is a porous structure, which is excellent in light weight, sound absorption, non-combustibility, energy absorption, heat insulation, electromagnetic shielding, and permeability, and is used as an environmental noise absorber and automobile shock absorber. It is used all over the industry, such as industrial equipment.

The foamed aluminum is poured into a crucible, followed by injecting aluminum molten metal into the crucible, followed by sequentially adding a thickener and a foaming agent, followed by stirring to uniformly mix the mixture. After holding to generate a large number of bubbles, the foamed aluminum is cooled and finished.

On the other hand, in order to supplement the problems caused by the high price of the foamed aluminum, and to efficiently increase the sound absorption and heat insulation performance, conventionally, a sound absorbing material such as glass fiber or rock wool should be used inside the composite panel. It is maintained in the position to maintain the sound absorption performance, but over time flows down by the weight of rain, moisture, wind, etc., the sound absorption performance is weakened, its life is extremely limited, and environmental pollution occurs when disposed Was done.

In addition, attaching the plated steel sheet to the surface of the foamed aluminum as a sound insulating material and a structural material causes problems such as difficulty in handling and a sound absorption performance due to the increase in overall load by the steel sheet.

The present invention has been made to solve the above problems, by attaching a paraboard molded by mixing the porous aluminum foam and expanded pearlite with an inorganic binder with an adhesive can maximize the effect of light weight, heat insulation, sound absorption The purpose is to provide a composite panel using paraboard and foamed aluminum.

The present invention is provided with a foamed aluminum layer of the porous structure formed through the process of thickening, stirring, foaming, cooling, by applying an adhesive to one surface of the foamed aluminum layer to form an adhesive layer, the expanded pearlite on the adhesive layer It is characterized by adhering the molded para-board mixed with the inorganic binder.

The present invention, by attaching a paraboard formed by mixing a porous aluminum foamed aluminum and expanded pearlite with an inorganic binder with an adhesive can maximize the effect of light weight, heat insulation, sound absorption.

In addition, by forming various patterns on the surface of the para-board there is an effect that can cause aesthetics.

The composite panel using paraboard and foamed aluminum according to the present invention is provided with a foamed aluminum layer of a porous structure formed through a process of thickening, stirring, foaming, and cooling, and applying an adhesive to one surface of the foamed aluminum layer to form an adhesive layer. Forming, and characterized in that to adhere the molded paraboard by mixing the expanded pearlite with an inorganic binder to the adhesive layer.

In addition, the surface of the para-board is characterized by coloring.

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

1 is a perspective view showing a composite panel using a para-board and foamed aluminum according to the present invention, Figure 2 is a cross-sectional view showing a composite panel using a para-board and foamed aluminum according to the present invention.

As shown in Figure 1 and 2, the composite panel using a para-board and foamed aluminum according to the present invention is provided with a foamed aluminum layer (1) of a porous structure formed through the process of thickening, stirring, foaming, cooling To form an adhesive layer (2) by applying an adhesive on one surface of the foamed aluminum layer (1), and to form a paraboard (3) formed by mixing expanded pearlite with an inorganic binder on the adhesive layer (2). .

The foamed aluminum layer (1) is injected into the crucible and the molten metal is injected, followed by stirring while adding a thickener and a blowing agent in order to be uniformly mixed, dropping the mixture passed through the process to the mold provided with a heating means and melting point It is formed by cooling the foam mold after maintaining the above temperature to produce a plurality of bubbles. In particular, the thickener is Ca, TiH 2 is mainly used as the blowing agent. On the other hand, the manufacturing process of the foamed aluminum layer is a known technique already well known by those skilled in the art, a detailed description thereof will be omitted.

Before the adhesive layer 2 is formed, it is preferable to clean various foreign matters and dusts on the surface of the foamed aluminum layer 1 and then apply an adhesive.

The para-board (3) refers to the fired after molding using an inorganic binder that is harmless to the expanded pearlite, and is characterized by excellent light weight, nontoxicity, heat insulation, nonflammability, and sound absorption.

The paraboard 3 is a sound absorbing nonflammable material, which is already widely used in building materials, industrial fields, acoustic facilities, environmental fields, soundproof walls, agricultural fields, and the like.

The expanded pearlite refers to a rock containing organic matter produced by rapidly cooling lava generated by volcanic activity in contact with water. The expanded pearlite is a rock containing about 3-5% of crystalline water and is usually gray or blue. After the pearlite is crystallized, it is rapidly heated to a high temperature of 870 ° C. or higher to vaporize the crystal water to produce porous particles. In particular, the expanded pearlite forms a large number of micropores in the particles as the crystallized water vaporizes inside, thereby resulting in light and unique physical properties.

Since the paraboard 3 contains a myriad of pores, the ultra-light weight is very small compared to the volume, so that the specific gravity of the application target can be lowered, and the sintered plastic is fired with a non-combustible inorganic binder.

In addition, as a myriad of porous particles are connected by point contact between particles, the solid conduction of the pearlite itself is very small, and the pores between the pearlite particles are filled with fine particles to prevent convection and excellent thermal insulation by radiation.

The paraboard 3 may be attached to either side of the foamed aluminum layer 1 or attached to both sides, or may be used by attaching the foamed aluminum layer 1 to both sides of the paraboard.

On the surface of the para-board, paints, paints, etc. are used to produce colors or patterns, causing viewers to induce aesthetics.

By the combination of the foamed aluminum layer (1) and the para-board (3) having the above characteristics, the performance of heat insulation and sound absorption is improved compared to the conventional foamed aluminum, and as a non-flammable material, there is no risk of fire and is non-toxic. It does not harm the human body at all.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include examples of many such variations.
