通常行なっている方法である。しかしこれらに使われて
いるバインダーは総て可燃性である。[Detailed description of the invention] 1. (Prior art) Since paper is composed of hydrogen bonds between cellulose, there is no need for a binder, or in the case of vinylon fibers or inorganic glass fibers that do not have hydrogen bonds. The commonly used method is to mix PVA or a fibrous material of PVA as a binder. However, the binders used in these products are all flammable.
また建築の内装工事で壁紙を貼る接着剤は醋酸ビニール

接着剤は可燃性の醋酸ビニール系のものが使われている
のが実状である。Also, acetic acid vinyl emulsion is used as the adhesive for pasting wallpaper in architectural interior work. Recently, the use of flame-retardant wallpaper has been regulated by the Building Standards Act, but the reality is that the adhesive used to paste these wallpapers is flammable acetic acid vinyl.

ラミック等無機繊維紙の抄紙バインダー及び内装工事用
難燃性壁紙接着剤として開発したものである。2 (Features of the invention) Flame-retardant phosphorylated starch was developed as a paper binder for synthetic fiber papers such as vinylon, inorganic fiber papers such as crow and ceramic, and as a flame-retardant wallpaper adhesive for interior construction.
燐酸化澱粉は無臭で淡い黄色の固体である、水に解ける
と強い粘着力を示す。Phosphated starch is an odorless, pale yellow solid that exhibits strong adhesive properties when dissolved in water.
又水中でカチオン性に帯電するのは構造式で判る様にア
ンモニア基を持っておりこれが水中でカチオンに帯電す
る。Also, as can be seen from the structural formula, it has an ammonia group, which becomes cationically charged in water.

オン結合することが従来から使用されているバインダー
と相違する慨である。Therefore, the more phosphorylation progresses, the stronger the cationic nature becomes. Note that wood bulbs, inorganic fibers, inorganic powders, etc. are all charged with anions in water, which is the complete opposite of phosphorylated starch, so they are different from conventionally used binders in that they form ionic bonds.
従来抄紙用バインダーは物理的な結合に基ずくものであ

煙りや災気は殆ど感じりれないのが特長である。In addition, polyvinyl alcohol (P), which is conventionally used in paper making,
When VA) burns, it emits a lot of smoke and a pungent odor, but phosphorylated starch only carbonizes even when ignited, so you can hardly feel any smoke or bad odor.
