JPH08319714A - Exterior wall coating construction of building to achieve arc thermal spraying of aluminum - Google Patents

Abstract

PURPOSE: To improve function by electrically melting an aluminum wire by an arc thermal spraying gun, atomizing molten aluminum into particles with a compressed air to be attached to the surface of an exterior wall to form an aluminum film. CONSTITUTION: Aluminum film of uniform thickness of about 10μm is formed by attaching aluminum 26 to the surface of an exterior wall 24 by an arc thermal spraying gun 14 even when the surface of the exterior wall 24 is rugged. Fire resistance of a building is improved by the aluminum film, and the fire resistance is also improved by the thermal reflection. Condensation is prevented by heat conduction of aluminum. Because the amount of aluminum is small, the weight load to the exterior wall 24 is reduced. In addition, when the aluminum surface is coated, the paint is impregnated in continuous pores in the thermal sprayed film to prevent the film from being peeled. The fire resistance, the corrosion resistance, the condensation resistance, etc., can be improved, and the environmental destruction can be prevented because the waste after use are reduced to the nature.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall coating method for a building using aluminum.

[0002]

BACKGROUND ART Aluminum is lightweight, heat reflective, corrosion resistant,
It is known that heat conduction is good. Most of the conventional uses of aluminum are those that apply this weight reduction, heat reflection, corrosion resistance, and heat conduction, for example, weight reduction,
Aluminum panels and aluminum fences for trucks are used for their excellent heat reflection and corrosion resistance, and heat sinks and fins for radiators are used for their heat conduction. In addition to this, there is an example in which it is not affected by magnetism and has good workability. In this way, most of the usage examples of aluminum are those that are usually applied in the shape of a plate by applying the advantage of metal, but chemicals, pharmaceuticals, fireworks,
There are also examples of heavy anticorrosion paint mixed with foaming agent of foam concrete, asphalt, etc. in powder form. By the way, as a result of researching the usage of aluminum, the present applicant did not use asphalt, etc., and regardless of the shape of the target object, at room temperature,
We have found a method that allows on-site construction. In other words, not using asphalt improves fire resistance,
It also eliminates the need for paint curing time after construction and curing due to paint scattering during construction. Regardless of the shape of the target object, if it is possible to perform on-site construction at room temperature, regardless of the material of the target object, it is possible to perform construction using the advantages of aluminum without weakening the strength of the target object. The present invention has been made by paying attention to various effects that such aluminum has, and an outer wall coating method using an arc spraying apparatus that can suitably utilize aluminum's heat reflection, corrosion resistance, heat conduction, etc. The purpose is to provide.

[0003]

The present invention has the following constitution in order to achieve the above object. That is, wire-shaped thin aluminum is electro-melted at the tip of the arc spray gun,
5.0k from melted aluminum from compressor
It is characterized in that a fine particle aluminum film is formed on the surface of the outer wall material by using an arc spraying device which makes fine particles with compressed air of about g / cm and adheres to the object.

[0004]

Function: Fine particle aluminum is delivered from the tip of the arc spray gun of the arc spray apparatus. The fine-grained aluminum delivered from the tip forms a film on the surface of the outer wall material, and the fire resistance, corrosion resistance, and dew condensation prevention effect of the outer wall material can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows an embodiment of an arc spraying apparatus according to the present invention. Reference numeral 10 is an arc spraying apparatus, which incorporates a power supply unit, an air delivery unit, and an electric control unit. One end of an electric wire cable 12 for electromelting aluminum is connected to the output side of the arc spraying apparatus 10, and the other end of the electric wire cable 12 is connected to an end portion of an arc spray gun 14. Further, one end of the control cable 20 and the air hose 2 are provided on the output side of the arc spraying device.
The other end of the control cable 20 and the other end of the air hose 22 are connected. In the embodiment, one end of the Teflon tube 16 for supplying electro-melted aluminum is connected to the carrying base 18, and the other end of the Teflon tube 16 is connected to the air gun 14. FIG. 2 is an enlarged schematic view showing a state in which the aluminum 26 is attached to the surface of the outer wall material 24. As shown in FIG.
Even when the surface is uneven, approximately 26 μm of aluminum 26 adheres and a substantially uniform film can be formed. Since the surface is particulate, the surface looks white and there is no obstacle to the reflection of sunlight. That is, forming an aluminum film on the surface of the outer wall material means building an energy-saving building that uses the heat reflection of aluminum, and the fire reflection performance is improved by the action of heat reflection, which means that an aluminum film is applied. Also improves fire resistance. In addition, the heat conduction of aluminum also makes it possible to prevent condensation. Although the present invention has been variously described above with reference to the preferred embodiments, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. is there.

[0006]

The shape of aluminum on the surface of the outer wall according to the present invention becomes close to a spherical shape of about 10μ by being sprayed by the arc spraying device. As a result, the heat conduction effect can be improved with a small amount of aluminum and the weight of the outer wall material attached can be reduced, so that the weight burden on the outer wall material can be reduced. Also, if airtightness is required, when coating the surface of aluminum, about 4% of the continuous pores in the micron unit of the thermal spray coating will impregnate the paint and will not peel off. It has a synergistic effect of improving the fire resistance performance of and improving the durability of aluminum by the overcoating paint. In this way, the advantages of aluminum can be exerted on the surface of the outer wall material, the adhesion strength is intermediate between painting and plating, and in terms of pollution prevention, aluminum is easy to dispose of after disposal and easily returns to soil and returns to the natural world. Besides, it has been experimentally proved that it is not absorbed into the body but is excreted into the digestive system.
