Abstract

(57) [Abstract] (Correction) [PROBLEMS] To prevent the plastic film from being separated from the inorganic fiber blanket when the inorganic fiber blanket body covered with the plastic film in a bag shape is cut. SOLUTION: A plastic film 2 is coated with an adhesive 4 on at least one of the front and back surfaces of the blanket.
And a ventilation hole 3b is provided in the plastic film 3 on at least the side surface. [Effect] Since the plastic film is adhered to the plate surface of the inorganic fiber blanket, the plastic film does not separate from the inorganic fiber blanket even after cutting, and the ventilation hole 3b provided in the plastic film 3 allows the inorganic fiber blanket body to be formed. When rolled up in a roll and compressed and packed, it is easy to escape air, making it easier to compress and pack.
Makes it easy for air to enter when unpacking.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an improvement of an inorganic fiber blanket body suitable for use as a heat insulating material for a building, a sound absorbing material, a fire insulating material for an industrial furnace, and the like.

[0002]

[Prior art]

 A structure in which an inorganic fiber blanket is covered with a plastic film bag has been proposed and put into practical use.

[0003]

[Problems to be solved by the device]

 However, as long as the plastic film-covered inorganic fiber blanket body does not scatter fibers as long as it is coated with a plastic film, if it is cut during the on-site construction, the inorganic fiber blanket and the plastic film will separate. Therefore, the structure cannot completely prevent the fiber from scattering. Therefore, there is a problem that it stimulates the skin of the body.

The present invention has been made in view of the above problems, and a plastic film (hereinafter, referred to as a film) is not limited to a fiber film (hereinafter, referred to as a blanket) while being handled and cut. The main purpose is to provide an inorganic fiber blanket body (hereinafter referred to as a blanket body) that can prevent the scattering of fibers without being separated from the above.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a blanket body in which the entire surface of a blanket formed into a plate shape is covered with a film, and at least one of the front and back surfaces of the blanket is bonded to a film by an adhesive, and The gist is that there are ventilation holes in at least the side film.

[0006]

[Embodiment of device]

 As a preferred embodiment of the present invention, as shown in FIGS. 1 and 2, two films 2 and 3 are used as a film for covering a blanket 1 formed into a plate shape, and a film 2 is blanketed with an adhesive 4. The film 3 that covers the blanket surface and the four side surfaces is provided on the back surface of the film 3 with ears that protrude from the periphery of the back surface. The heat-sealing seal portion 5 was formed by superposing the heat-sealing layer 2a on the surface 2a and heat-sealing it, and a number of ventilation holes 3b were provided on the surface of the film 3 facing the side surface of the blanket.

[0007]

【Example】

 1 and 2 show an embodiment of the present invention. In FIGS. 1 and 2, reference numeral 1 is a blanket formed by molding ceramic fibers into a plate shape, and the blanket is entirely covered with two polyethylene films 2 and 3 having a thickness of 30 μm.

Of the films 2 and 3, one of the films 2 has a size that covers the back surface of the blanket 1 and projects from the periphery of the back surface, and is applied on the film excluding the protruding ears 2a. It is adhered to the back surface of the blanket with the asphalt-based adhesive 4. The other film 3 has a width that covers the opposite surface and four side surfaces, and has an ear portion 3a that is bent outward from the side surface and overlaps with the ear portion 2a of the film 2. The ears 3a on the four sides of the film 3 and the ears 2a of the film 2 are sealed by heat fusion. 5 is a heat-sealing seal part. The film 3 has a large number of air holes 3b formed on the surface facing the side surface of the blanket 1.

In the inorganic fiber blanket body having the above-mentioned structure, the blanket 1 is entirely covered with the polyethylene films 2 and 3 in a bag shape, so that fibers are not scattered during handling. Also, since the surface of the blanket body 1 is adhered by the film 2, the film and the blanket do not separate even when cut and the fibers can be suppressed from scattering.

In addition, the ventilation hole 3b provided in the film 3 facilitates the escape of air when compressed by rolling in a roll and facilitates compression packing, and facilitates the inflow of air when unpacking. , Facilitate blanket volume restoration. Further, when it is installed in a furnace, the blanket body covering film is burned off by the first firing, so that the fireproof heat insulation performance of the blanket body is not affected.

Although the back surface of the blanket is adhered to the film in the above embodiment, the front and back surfaces may be adhered to the film. Furthermore, the adhesion is not limited to the entire surface adhesion, but may be partial adhesion. Further, an adhesive may be applied to the entire surface of the film 2 including the ears 2a, and the ears 3a of the film 3 may be bonded to the ears 2a. In that case, the heat sealing of the ears does not occur. It becomes unnecessary.

The conventional ceramic fiber blanket covered with a bag made of a plastic film has a problem that the bag and the blanket come off when cut, making it impossible to carry out the construction and scattering the fibers. The film did not come off the blanket even after cutting, and there was little fiber scattering, and good construction was possible.

[0013]

[Effect of device]

 As described above in detail, according to the present invention, since the entire blanket is covered with the plastic film in the shape of a bag, the fibers do not scatter during handling, and the scattering of the fibers is suppressed even if the fiber is cut. An inorganic fiber blanket body capable of being obtained is obtained. In addition, when the inorganic fiber blanket body is wound in a roll shape and compressed and packed by the ventilation holes provided in the plastic film, air is easily released to facilitate the compressed packing, and when unpacked, air is introduced to allow the inorganic fiber blanket to be packed. It has the effect of facilitating the restoration of the body volume.
