DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for forming a heat insulating layer for piping, etc., and a heat insulating sheet.

(Conventional technology) Conventionally, as a means of insulating pipes, a heat insulating material or heat insulating material was wrapped around the pipe, or a pair of separate heat insulating materials were assembled from both sides of the pipe, and a dave was wrapped around the pipe to secure it. After that, it is common to paint as necessary. In addition, asbestos, rock wool, glass wool, polyethylene foam, etc. are used as the heat insulating material.

(Problems to be Solved by the Invention) However, with this type of heat insulating material, it is extremely difficult to cover curved and bent parts of the pipes, and gaps are created between the pipes and the heat insulating material, resulting in a poor heat retaining effect. There are drawbacks to reducing this. Also,
The insulation material is fixed by wrapping it with tape, which takes a considerable amount of time to install and is not very easy to work with. Furthermore, since the outer periphery of the heat insulating material is painted and dried if necessary, the construction period becomes longer.

(Object of the Invention) The present invention has been made in view of the above circumstances, and its purpose is to provide a structure that can be easily installed without creating gaps even in bent portions of pipes and valves, and has excellent workability and heat retention. An object of the present invention is to provide a method for forming a heat insulating layer for piping, etc., and a heat insulating sheet.

(Means for Achieving the Object) In order to achieve the above object, the present invention includes a base film, a foam coating agent coated on the film and heated and foamed, and a film covering the foam coating agent.
It uses a new heat-retaining sheet consisting of a film with adhesive attached to one side edge.

Further, in forming a heat insulating layer on the pipes, the heat insulating sheet is cut to a predetermined size to cover the pipes, and then both ends of the sheet are joined with the above-mentioned adhesive.

For piping that requires only a thin heat insulating layer (low foaming), use a heat-shrinkable or biaxially stretchable base film; for piping that requires a thick heat retaining layer (high foaming), use the base film. An aluminum vapor-deposited film is used for the film.

(Example) FIG. 1 shows a heat-retaining sheet 10 according to the present invention. This sheet 10 is formed by applying a foaming coating agent 12 to the surface of a base film 11 and then heating and foaming it. In this example, "Thermocell" (product name)
We use a foam coating agent called 1,200 to 130 degrees Celsius, in which the butane gas inside expands and foams, and the thickness after foaming reaches 4 to 15 times.

The foam coating agent 12 is applied to the base film 11 leaving only one side edge, and an adhesive 13 is applied to this negative side edge along the longitudinal direction. It is desirable that the sheet 10 be wound up into a roll in advance and pulled out by the required amount. In addition, a non-adhesive protective tape 1 is applied to the surface of the adhesive 13 so that the sheet 10 in the 1-call state is in close contact with the adhesive 13.
4 is provided.

For the base film 11, a heat-shrinkable film or a biaxially stretchable film is used in the case of a thin heat-retaining layer (low foaming), and an aluminum vapor-deposited film is used in the case of a thick heat-retaining layer (high foaming). When an aluminum vapor-deposited film is used, radiant heat from the pipes is reflected on the film, improving the heat retention effect of the sheet 10.

Furthermore, in order to prevent moisture from the pipes from having an adverse effect on the heat insulating layer, the surface of the foamed coating agent 12 is covered with a film 11a, as can be seen from FIG. The film 11a is made of the same material as the base film 11.

To increase the strength of the heat retaining layer, glass wool, filter material, or nonwoven fabric is impregnated with the foam coating agent 12 and heated and foamed.

Next, a method for attaching the heat insulating sheet 10 will be explained. First, a required amount of sheets 10 is pulled out from a roll of sheets 10 and cut as shown in FIG. Subsequently, the protective tape 14 is peeled off, and the sheet 10 is wrapped around the pipe 15 as shown in FIGS. 4 and 5, and both ends of the sheet 10 are joined with the adhesive 13. Sheet 1 without covering film 11a
When ~ is used, it is installed so that the layer of foam coating agent 12 is on the inside.

従来のテープ巻きと異なり、シート10は引張りながら

間が生ずることはない。
Unlike conventional tape wrapping, the sheet 10 is wrapped around the piping 10 while being stretched, and both ends are joined as is, so the sheet 10 will not loosen or a gap will occur between the heat insulating layer and the piping 15.

This method is particularly effective when it is not possible to heat the foam coating agent 12 at the piping site. Moreover, since the base film 11 can be colored, the steps of painting and drying the outer surface of the sheet can be omitted.

配管15が長い場合には、シート10を何段かに分けて

If the piping 15 is long, the sheets 10 can be installed in several stages and the joints of each sheet 10 can be covered with a film of the same type as the base film 11 to achieve a neat finish.

Also shown in FIGS. 6 and 7 are different uses of the sheet 10. In the embodiment of FIG. 6, the adhesive 13 of sheet 10 is used to cover the seam between adjacent sheets. That is, the adhesive 13 portion of the sheet 10 is attached to the pipe 15 with the adhesive 13 on the right side in FIG.
It is pasted around the top of the . In the embodiment shown in FIG. 7, the sheet 10 is wound around the pipe 15 in a spiral manner.

With such a configuration, there is no need to specially post-process the seams of each sheet 10.

(Effects of the Invention) As explained above, if the method for forming a heat retaining layer and the heat retaining sheet of the present invention are adopted, the sheet can be easily formed without creating gaps even at bent parts of piping or places with complicated shapes. can be attached and provides excellent heat retention. In addition, since the outer surface of the sheet is made of a colorable film, the appearance after installation is beautifully finished, and it is possible to maintain harmony with the surroundings.
