本発明はロックウールなどからなる鉱物質繊維板の製造
方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing mineral fiberboard made of rock wool or the like.
従来の鉱物繊維板の製造方法はロックウールにアスベス
トの代替材料として七ビオフィトを用いて抄造すること
は公知であるがとの七ビオライトの電荷特性が両性とな
っているためにマイナス電荷をもつロックウールに対す
る吸音が弱いために曲げ強度が弱くなったりするという
欠点があった。It is known that the conventional manufacturing method of mineral fiberboard is to use rock wool with heptabiophyte as an alternative material for asbestos, but since the charge characteristics of heptabiolite are amphoteric, rock has a negative charge. There was a drawback that the bending strength was weakened due to the poor sound absorption of wool.
又、セピオライト単独では濾過抵抗（フリーネス）が低
下するために抄造時の幅方向の坪量分布が不均一となり
やすいために加工時に表面切削を多くしなければならな
かったり抄き上げ後の表面地合いが悪くなったりすると
いう欠点があった。In addition, when using sepiolite alone, the filtration resistance (freeness) decreases, which tends to result in uneven basis weight distribution in the width direction during papermaking. It had the disadvantage that it could make things worse.
又、抄き上げ材料、特にバインダーとしての澱粉歩留り
が悪くなるものであった。In addition, the yield of the papermaking material, especially starch as a binder, was poor.
本発明は上述した背景技術に鑑みてなされたものでその
目的とするところはセピオライトのロックウールへの定
着化を図シ曲げ強度が大なる鉱物繊維板を得るとともに
抄造時の濾水性を向上させしかも材料歩留如の良好な鉱
物繊維板の製造方法にある。The present invention has been made in view of the above-mentioned background art, and its purpose is to improve the fixation of sepiolite to rock wool, obtain a mineral fiber board with high bending strength, and improve freeness during paper making. Moreover, the present invention provides a method for producing mineral fiberboard with good material yield.
以下、本発明の実施例に基づいて説明する。 Hereinafter, the present invention will be explained based on examples.
ロックウール等の鉱物繊維にセビオツイト、シリカなど
の充填剤、澱粉などのバインダー、ワックヌなどの撥水
剤、澱粉定着剤をスラリー化して、そして少量のポリア
ミドポリアミンエピクロヒドリン樹脂の強力チオン樹脂
をこのスラリー中に添加して丸網式抄造機によって鉱物
繊維生板を得、しかる後乾燥機で乾燥後切断して厚さ坊
驕、輻ｉｏｏｏｍ、長さ２０００（１）の鉱物繊維板を
得た。下表に本発明の実施例と比較例の配合と特性を示
す。Mineral fibers such as rock wool are slurried with fillers such as Cebiotite and silica, binders such as starch, water repellents such as Wacnu, and starch fixatives, and then a small amount of strong thione resin such as polyamide polyamine epichlorohydrin resin is added. It is added to this slurry to obtain a green mineral fiber board using a circular mesh paper making machine, and then dried in a dryer and cut to obtain a mineral fiber board with a thickness of 2,000 mm and a length of 2000 (1). Ta. The table below shows the formulations and characteristics of Examples of the present invention and Comparative Examples.
上表のように、実施例１及び実施例２では強力チオン樹
脂の添加量を０．０１％と０．２％と変化させたもので
あって各々の曲げ強度は比較例の強力チオン樹脂を添加
しないものと比較すると加〜３５％も向上していること
がわかる。又、濾過抵抗（フリーネス）は比較例より丞
〜５６％も増大しているので抄造時の幅方向の坪量分布
が均一なものとなる。さらに、澱粉歩留りも良好である
。As shown in the table above, in Examples 1 and 2, the amount of strong thione resin added was changed to 0.01% and 0.2%, and the bending strength of each was higher than that of the strong thione resin of the comparative example. It can be seen that the improvement is 35% compared to the one without the addition. Furthermore, since the filtration resistance (freeness) is increased by ~56% compared to the comparative example, the basis weight distribution in the width direction during paper making becomes uniform. Furthermore, the starch yield is also good.
以上のように、本発明はセビオツイトの定着剤として少
量の強力チオン樹脂をスラリー中に添加するととによっ
て両性のセピオライトの電荷特性ハ強カチオン樹脂によ
ってカチオン化される。そのために七ビオライトはプラ
ス電荷を屯っようになりロックウールのマイナス電荷に
吸着され曲げ強度が大となる。又、セピオツイトはロッ
クウー〃に吸着されるために側渦抵抗が増大して濾過時
間が長くなり抄造時の幅方向の坪量分布が均一となる。As described above, in the present invention, when a small amount of a strong cationic resin is added to the slurry as a fixing agent for sepiotite, the charge characteristics of amphoteric sepiolite are cationized by the strong cationic resin. For this reason, the Seven Biolite has a positive charge and is attracted to the negative charge of rock wool, increasing its bending strength. In addition, since sepiotite is adsorbed by rock wool, the side vortex resistance increases, the filtration time becomes longer, and the basis weight distribution in the width direction during papermaking becomes uniform.
さらに坪量分布が均一となるために加工時の表面切削量
も減少させることができ、しかも抄き上げ後の鉱物繊維
板の表面地合いも良好となる。Furthermore, since the basis weight distribution becomes uniform, the amount of surface cutting during processing can be reduced, and the surface texture of the mineral fiber board after cutting becomes good.
又、澱粉の歩留りも強力チオン樹脂の影響によって向上
する。In addition, the starch yield is also improved due to the influence of the strong thione resin.
