（例えば、特開昭６３−３０４８号公報の明細書第３頁
第３〜６行）。2. Description of the Related Art As a conventional soundproofing material, there is a material in which an inorganic filler such as calcium carbonate or aluminum hydroxide is mixed in a large amount in an organic binder material to form a sheet (for example, Japanese Patent Application Laid-Open No. Sho 63-3048). No. 3, page 3 to line 6).

を提供することを目的とする。The conventional soundproofing material has good workability and sound-insulating effect with respect to a flat base material, but has a good effect on a curved base material or a base material having an uneven portion. In this case, sound is leaked from a joint formed between the soundproofing materials or a joint formed between the soundproofing material and another member at the time of execution, and a predetermined sound insulation effect cannot be obtained. Then, this invention was made in order to solve such a problem, and an object of this invention is to provide the sound insulation material excellent in workability and a sound insulation effect.

得る上で不適である。As the metal powder, one or more metal powders of aluminum, copper, brass, zinc, titanium, stainless steel, nickel, steel, cast iron and alloys thereof are used, preferably those having a mesh size of 30 or less. Is added to the organic binder in an amount of 25 to 900 parts by weight based on 100 parts by weight of the organic binder.
When the amount exceeds 00 parts by weight, the bulk density of the soundproofing material becomes large, which is not suitable for obtaining fluidity as a spraying material and adhesion to a wall surface.

In addition , the sound insulation can be easily given by the mixing degree of the cast iron powder of 30 mesh or less, light weight, excellent shape retention, and vibration suppression performance against sound waves. Energy is converted to heat energy and attenuated by mutual friction between the organic binder and the metal powder.

１．２ｍｍの塩化ビニルシートである。EXAMPLES The present invention will be described in detail with reference to examples. (Example) Cast iron powder (30 mesh under) was added to 60 parts by weight of styrene-butadiene emulsion.
When a spray material added with 0 parts by weight and kneaded is sprayed on release paper with a spray gun, and the cured sheet-like member is separated from the release paper, a soundproof material having a thickness of 1.2 mm is obtained. Comparative Example A comparative example is a vinyl chloride sheet having a surface density of 2.22 kg / m 2 and a thickness of 1.2 mm.
【０００９】次に、本実施例の防音材および比較例の塩

Metal powder based on parts by weight , preferably 30 mesh amps
And 25 to 900 parts by weight of the cast iron powder , so that it is excellent in shape-retaining and sound-insulating effects, and because it is lightweight, it can reduce the weight of the structure. Even when the spraying operation is performed by the spraying gun, the workability is good because it is lightweight, and the working environment is not polluted because no dust is generated. Also,
Since the weight loss is inexpensive and the thickness can be remarkably reduced as compared with the conventional spraying material of this type, the cost can be significantly reduced.
