Description

Insulation Cladding {COVERING MATERIAL FOR INSULATION}

The present invention relates to a heat insulating coating material, in particular a heat resistant coating material having good fire resistance and corrosion resistance covering the exhaust manifold of an internal combustion engine.

In particular, the present invention is a superimposed edge by sequentially layering a ceramic cloth, a ceramic cotton mat and an aramid fiber cloth bonded to an aluminum foil on one side in order to prevent heat from the exhaust manifold heated to high temperature by the exhaust gas to the engine room, etc. The present invention relates to a heat insulating coating material which is integrally formed by sewing a part intermittently.

The exhaust manifold is one component of an exhaust device that collects exhaust gas discharged from each cylinder of a multicylinder engine and exhausts it to the atmosphere through an exhaust pipe and a silencer.

In general, the exhaust manifold is heated to about 900 ° C. by hot exhaust gas when the engine is driven, so that the temperature in the engine room is rapidly increased by heat transfer through the exposed surface. Such an increase in the temperature of the engine room reduces the insulation efficiency of the electrical components contained in the engine room or damages the electrical components, as well as reduces the cooling efficiency of the engine cooling system. Cause.

One method proposed to solve this problem is to sew the edge of the ceramic cloth and the glass fiber integrally formed, and then cover the exhaust manifold with a Teflon-coated heat insulating coating material to cover the exhaust manifold. This technology prevents heat from being heated in the engine room.

However, such a technique generates scattering dust as the Teflon coating deteriorates, contaminates an engine or engine room including an exhaust manifold, and exposes glass fibers to emit a large amount of scattering dust harmful to a human body. Therefore, the conventional heat insulating coating material has a problem that the Teflon coating is deteriorated and peeled off, and together with a large amount of scattering dust generated from the glass fiber, the heat insulating effect is reduced, and frequent replacement is required.

Accordingly, the present invention was created in view of the above problems, and an object thereof is to provide a heat insulating coating material having excellent fire resistance and corrosion resistance.

50: coupling means 100: heat insulating coating material

The object of the present invention is a ceramic cloth, a ceramic cotton mat positioned on the top surface of the ceramic cloth, an aramid fiber cloth positioned on the top surface of the ceramic cotton mat and bonded to an aluminum foil on the top surface, and each sequentially layer It can be achieved by a heat insulating coating material comprising a bonding means for integrating the ceramic cloth, ceramic cotton mat and aramid fiber cloth.

Here, the joining means is a refractory fiber or metal yarn which intermittently stitches and integrates the overlapping edge portions of the ceramic cloth, the ceramic batting mat and the aramid fiber cloth.

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

1 is a view showing a state in which the exhaust manifold of the engine is covered by the heat insulating coating material of the present invention, Figure 2 is a perspective view showing a part of the heat insulating coating material according to an embodiment of the present invention.

Referring to Figure 1, the heat insulating coating material 100 of the present invention is a screw type is coated on the exhaust manifold (EM) so that the heat of the exhaust manifold (EM) heated by the exhaust gas does not heat transfer to the engine room (not shown) It is clamped to the surface of the exhaust manifold EM by the clamp CL. Here, although FIG. 1 shows that the insulation covering material 100 is limited to being clamped to the surface of the exhaust manifold EM by the clamp CL, the exhaust manifold is not limited thereto but wound by a wire or by various other methods. (EM) may be provided.

Referring to the configuration of the heat insulating coating material 100 of the present invention with reference to Figure 2, the heat insulating coating material 100 is aramid bonded to the aluminum foil 30 on the ceramic cloth 10, the ceramic cotton mat 20 and one side. The fiber cloth 40 is sequentially layered, and the overlapping edge portion is intermittently stitched by a fastening means 50 such as fireproof fiber or metal yarn to have a triple structure integrally formed. Here, the ceramic cloth 10, the ceramic wool mat 20, and the aramid fiber cloth 40 are materials having a good fire resistance that do not deteriorate or thermally deform when covering the exhaust manifold EM heated to about 900 ° C.

In addition, the aramid fiber cloth 40 is provided to reinforce the fire resistance of the ceramic cloth 10 and the ceramic cotton mat 20, in particular, the aluminum foil 30 adhered to the upper surface of the aramid fiber cloth 40 is the outside As well as preventing moisture from entering, there is a feature that can easily remove oil stains on the surface.

Although the present invention has been described in the above-described embodiments, the present invention is not limited thereto, and the present invention is not limited thereto, and the overlapping portions of the insulating coating material may be quilted with refractory fibers or metal yarns, or a ceramic cloth other than aramid fiber cloth. Various modifications may be made to the same structure using other fireproof materials.

As described above, the structure according to the present invention has the following effects.

First, it is a triple structure having good fire resistance and corrosion resistance and can semi-permanently insulate the exhaust manifold of the engine.

Second, there is no pollution of the engine or engine room due to deterioration of the Teflon coating because it does not adopt the Teflon coating, it is possible to easily remove contaminants when the surface contamination by oil.

Third, there is an excellent thermal insulation effect between the exhaust manifold and the engine room, so that even if the cab is provided adjacent to the engine room inside the iron armor, such as a tram, it is possible to create a comfortable driving atmosphere for the occupant.
