2. Description of the Related Art Curtains have long been employed for the purpose of adjusting lighting in living spaces and blocking noise.

A sheet coated with a foamed emulsion resin has been disclosed as a sheet for light shielding, noise shielding, sound absorption, etc. (JP-B-59-10740).

[0004] In addition, carpets and the like are laid on the flooring in order to obtain heat insulation and cushion.

[0005]

In the case of lighting control and noise blocking by a curtain, a curtain rail is necessary, and the lighting control depends on the degree of opening and closing of the curtain and adjusts the lighting evenly from the entire window. This is not possible, and when adjusting the ventilation, a hindrance occurs such that the suspended curtain swings and lighting becomes unstable.

In particular, there is a limit in the control of lighting by a curtain in a huge glass window or a glass window (wall surface) having a curved surface, and measures such as imparting a light shielding property to the glass itself are taken.

[0007] Further, in the foamed emulsion resin coating sheet, since the surface of the coating layer is uneven due to foaming, it cannot be adsorbed on a wall or glass surface by itself, and an adhesive layer is formed on the coated surface. Or using a double-sided adhesive tape.

A carpet is laid on the flooring. The carpet is fixed with a double-sided adhesive tape in order to prevent the displacement.

[0009] In the conventional technique of sticking in this way, once pasted, it cannot be easily peeled off, and a trace of the sticking layer remains on the trace that has been peeled off. Not only is it difficult to change the pattern casually, but also the flooring is very ugly as the paint on the surface finish comes off.

In view of the above-mentioned problems of the prior art, the present invention does not peel off or displace in a normal state by adsorbing on a smooth surface such as glass, tile, enamel, or painted surface, and easily when required. Woven fabric, non-woven fabric, which can be peeled and moved, leaving no trace after peeling
It provides suction sheets made of knit, paper, plastic, and metal foil sheets. Above all, it is difficult to control the lighting of large glass windows and curved glass windows (wall surfaces), which has been difficult in the prior art. An object of the present invention is to provide an adsorption sheet that can easily change a room design.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method of adding a foam stabilizer, a thickener, and a crosslinking agent to a mixture of an acrylic resin emulsion and a urethane resin emulsion, and forming the mixture by mechanical foaming. The foamed resin emulsion was coated on one side of a sheet, and the surface of this coating layer was shaved to open air bubbles to make the surface smooth and crosslinked by heating. Selected from paper, plastic, metal foil, or woven, non-woven, knit,
Paper, one obtained by laminating one selected from plastic and metal foil, or a resin composition containing metal powder in one selected from woven fabric, nonwoven fabric, knit, paper, plastic It is formed by coating, or by coating a resin composition containing a metal oxide on one selected from woven fabric, nonwoven fabric, knit, paper, and plastic.

The amount of the foam stabilizer is 2 to 5 parts by weight based on 100 parts by weight of the resin solids, and 3 to 5 parts by weight of a crosslinking agent is added.

If the amount of the foam stabilizer is less than the above range, the size of the bubbles varies, and fine and fine bubbles cannot be obtained. On the other hand, if it exceeds the above range, the foaming is suppressed too much and the adsorbability is impaired.

If the amount of the crosslinking agent is less than the above range, the shape of the air bubbles is not fixed. When the surface of the coating layer is shaved by a doctor knife, the air bubbles are crushed and the adsorptivity is reduced. The flexibility is impaired, resulting in poor adsorbability.

According to the present invention having the above-described structure, the coating layer formed on the surface of the sheet becomes a fine microbubble layer of 100 μm to 300 μm having appropriate flexibility, and the surface of the coating layer is scraped off. As a result, an adsorption sheet having a smooth surface with fine bubbles opened by removing irregularities due to bubbles is obtained. Especially when the printed fabric is used as a sheet, it can be decorated according to the season.

The adsorbing sheet thus obtained can be used for controlling and lighting a glass wall, especially a curved glass surface, a defrosting sheet for a front or rear glass of an automobile,
It can be used as a heat ray reflection sheet for automobile front, rear or window glass, a deodorizing sheet that also serves as interior decoration, a computer mouse operation mat, a table cloth, a coaster, a poster, and a projection screen.

Further, by using the above-mentioned sheet as a heat insulating / cushion layer, it is possible to obtain a carpet or other rug that does not shift its position laid on the flooring.
