ーパーコアに採用した場合コアが膨張するという欠点が
あった。Hard paper foot has recently been used as a core material for construction materials and furniture in some cases, but the surface of the paper core sheet made of pre-produced kraft paper is coated with phenolic resin to increase its strength. We are trying to increase this number. However, products made using this method are simply coated with phenolic resin on the surface of pre-produced ordinary kraft paper, so the inside of the paper is not impregnated with phenolic resin, so sufficient reinforcement is required. could not be administered. In addition, since sheets are always cut into a certain length and shape before use, they often inhale moisture from the atmosphere through the cut surfaces and have the disadvantage of stretching during use. The drawback was that the core expanded.
そのとフェノール樹脂はその性質上人体に有害であるた
め二次的欠点のあることは否定できなかった。Since phenolic resin is harmful to the human body due to its nature, it could not be denied that it had secondary drawbacks.

−トを得る方法である。The basic structure of the present invention is to spray at least S wt % of acrino resin solution onto a sheet-like raw material for a vapor sheet during or after the press process of the paper manufacturing process, and then spray the acrylic resin into the raw material. Paper V impregnated with resin and containing sufficient acrylic resin in the sheet-like raw material
- This is a way to obtain
この発明の詳細を添付図面を参照して説明する。The details of the invention will be explained with reference to the accompanying drawings.

上工程を行ない、巻取り軸１０に巻取って硬質ベーパー
シートを得る方法である。As is known, the liquid raw material 2 for vapor sheets stored in a beater is supplied onto an endless wire mesh 3 to obtain raw material l for vapor sheets. The raw material for the vapor sheet is supplied to the rotating felt, non-woven fabric, futon, etc., which absorbs water, and is sandwiched between the rollers A and 6 and pressed, during or after this press process.
Cs N 10% by weight or at least 4. % by weight of acrylic resin liquid is impregnated into the raw material μ through a spraying tool 7, this raw material L is dried through a heating roller, and further passed between a number of adjusting rollers. This is a method of performing a finishing process and winding it up on a winding shaft 10 to obtain a hard vapor sheet.
この発明は上記の構成であるから以下の利点を有する。Since the present invention has the above configuration, it has the following advantages.
（ｈ シートの内部まで確実にアクリル樹脂が含浸され
るから、強度に秀れた硬質ベーパーシートが得られる。(h) Since the inside of the sheet is reliably impregnated with the acrylic resin, a hard vapor sheet with excellent strength can be obtained.
− アクリル樹脂を含浸剤として採用したから、人体に
有害でないことはもとより、フェノ−／Ｉ／樹脂を採用
したｖ４合に比較して加熱ローラーによって乾燥処理を
行ってもローラーに原料が成金することが一切ない。- Since acrylic resin is used as the impregnating agent, it is not harmful to the human body, and compared to v4 which uses phenol/I/resin, the raw material does not form on the roller even when drying with a heated roller. There is no such thing.
ａ） この発明では従来の製紙工程を変化さ亡なくとも
よいから、既存設備を利用して安価に実施できる。a) Since the present invention does not require any changes to the conventional paper manufacturing process, it can be implemented at low cost using existing equipment.
