、吸音性に優れた吸音材として広く使用されている。(Prior art) Mineral fibers such as glass fibers and rock wool are deposited in a non-directional manner while being given an uncured binder, and heated while being compressed to a predetermined density to harden the binder. Glass fiber boards, rock wool boards, etc., which are obtained by bonding mineral fibers together using this binder, are widely used as light-weight sound-absorbing materials with excellent sound-absorbing properties.
又、鉱物質繊維板は外観が良好てないため、外観を良好
とし、又繊維の飛散を防止するために。In addition, mineral fiberboard does not have a good appearance, so we need to improve the appearance and prevent fibers from scattering.
鉱物質繊維板を内装材として使用する場合、その表面に
塩化ビニルフィルム等の表皮材を貼着することか広く行
われている。When mineral fiberboard is used as an interior material, it is widely practiced to attach a skin material such as vinyl chloride film to its surface.
（発明が解決しようとする課題）
上述した従来の鉱物質繊維製吸音材においては、鉱物質
繊維同志を結合するための結合剤として、熱硬化性樹脂
のような有機質結合剤が使用されている。(Problem to be Solved by the Invention) In the conventional sound absorbing material made of mineral fibers described above, an organic binder such as a thermosetting resin is used as a binder to bind the mineral fibers together. .
このため、鉱物質繊維製吸音材は、耐熱性、難燃性、不
燃性か不充分であり、又使用中紫外線の作用により詰合
剤か劣化し、繊維か飛散し易くなる難点がある。For this reason, sound absorbing materials made of mineral fibers have insufficient heat resistance, flame retardancy, and non-combustibility, and also have the disadvantage that the packing agent deteriorates due to the action of ultraviolet rays during use, and the fibers tend to scatter.
表被材を貼着すると吸音性か低下するたけてなく、火災
中に表被材が延焼し、煙を発生する。表被材として塩化
ビニルフィルムを使用すると、火災時に有毒な塩素ガス
を含んだ煙か発生し、人命か失われることも生ずる。If a surface material is attached, the sound absorption properties will be significantly reduced, and during a fire, the surface material will spread and generate smoke. If vinyl chloride film is used as a surface material, smoke containing toxic chlorine gas will be emitted in the event of a fire, resulting in loss of life.
また１表被材に静電気か発生し、塵埃がこの静電気によ
って吸着され、表面か汚れ易い欠点かある。Another disadvantage is that static electricity is generated on the surface material, and dust is attracted by this static electricity, making the surface easily dirty.
これらの欠点を改良するため、結合剤中に難燃剤を添加
する等、結合剤を難燃化することも試みられているか、
結合剤を難燃化すると結合力か低下するため、多量の結
合剤を使用する必要か生じ、コストが増大するたけでな
く、嵩比重か増大する難点が生じ、しかも充分な不燃性
をつることができない。In order to improve these drawbacks, have there been any attempts to make the binder flame retardant, such as by adding flame retardants to the binder?
When the binder is made flame-retardant, the bonding strength decreases, making it necessary to use a large amount of binder, which not only increases cost but also increases the bulk specific gravity, and it is difficult to obtain sufficient non-flammability. I can't.
無機質結合剤を使用することも試みられているか、無機
質結合剤を使用すると、無機質結合剤はｐＨか大きいた
め、鉱物質繊維か劣化し易い。Attempts have also been made to use an inorganic binder, but if an inorganic binder is used, the mineral fibers tend to deteriorate due to the high pH of the inorganic binder.
鉱物質繊維製吸音材の表面に、有孔金属薄板を接着する
ことも検討されているか、吸音材と金属薄板との接着か

音性能か大幅に低下し、吸音材の重量か増加し、軽量と
いう利点か失われる難点か生ずる。Adhesion of a perforated thin metal plate to the surface of a sound absorbing material made of mineral fibers has been considered, but it is difficult to bond the sound absorbing material and a thin metal plate, as both are easy to peel off, and the use of adhesive makes it non-flammable. Sexuality worsens. If a large amount of adhesive is used to prevent peeling, the nonflammability will be significantly deteriorated, the sound absorption performance of the sound absorbing material will also be significantly reduced, the weight of the sound absorbing material will increase, and the advantage of light weight will be lost. .
更に又、金属板を使用すると、金属板は取扱中に傷が生
し易く、外観不良か発生する。Furthermore, when a metal plate is used, the metal plate is easily damaged during handling, resulting in poor appearance.
本発明は、上述の問題点を解消し、耐熱性、吸音性、不

吸音材並びにその製造法を提供することを目的としてい
る。The present invention solves the above-mentioned problems, has good heat resistance, sound absorption, nonflammability, and appearance, does not scatter fibers during use, does not attract dust, and is easy to manufacture. The purpose of this research is to provide a nonflammable sound absorbing material and a method for producing the same.
