Definitions
- the present invention relates to a bulking agent for a fiber-mixed board as a building material board.
- This application is based on Japanese Patent Application No. 2022-132235 filed on August 23, 2022, and the contents thereof are incorporated herein.
- Pulp bulking agents used in the paper manufacturing field include paper bulking agents containing higher alcohols and their alkylene oxide adducts (Patent Document 1), and paper bulking agents containing oils and fats or sugar alcohol-based nonionic surfactants.
- paper bulking agents containing alkylene oxide adducts of fatty acids Patent Document 3
- paper bulking agents containing cationic compounds, amines, acid salts of amines, and amphoteric compounds Patent Document 4
- paper bulking agents containing polyhydric alcohol fatty acid esters Patent Document 5
- paper bulking agents containing compounds obtained by reacting epihalohydrin with compounds obtained from aliphatic carboxylic acids and polyamines Patent Document 5
- 6) is known.
- Patent Document 7 discloses, as a method for manufacturing a bulky inorganic plate, a method in which alkoxysilanes are added to a slurry, and foaming is promoted by mixing and stirring to include fine bubbles.
- Patent Documents 1 to 6 are added to acidic to neutral slurries. For this reason, the inventors of the present invention have found that a sufficient bulking effect cannot be obtained in a fiber-mixed board in which the slurry has strong alkaline liquid properties. Further, the slurry of the fiber-mixed board has an extremely high concentration of calcium ions. For this reason, the inventors of the present invention have found that even if a paper bulking agent applied to objects that do not have a high calcium ion concentration is used in a fiber-containing board, a sufficient bulking effect cannot be obtained.
- Patent Documents 1 to 6 are added to acidic to neutral slurries. For this reason, the inventors of the present invention have discovered that a sufficient bulking effect cannot be obtained in ceramic siding boards whose slurry is often alkaline. For this reason, a technique is desired that improves the bulkiness of fiber-mixed boards in building material boards.
- the present invention has been made to solve the above problems, and can be realized as the following forms.
- a bulking agent for a fiber-mixed board as a building material board is provided.
- This bulking agent for fiber-mixed boards is a bulking agent used for fiber-mixed boards as building material boards containing cement and pulp, and contains an ether compound (A) represented by the following general formula (F1) and the following general formula. It is characterized by containing at least one of the following: an ester compound (B) represented by formula (F2); According to the bulking agent for a fiber-mixed board of this form, the bulkiness of the fiber-mixed board as a building material board can be improved.
- R1a and R2a are the same or different and each represents a hydrogen atom or a saturated or unsaturated hydrocarbon group having 1 to 50 carbon atoms
- R1b and R2b are the same or different and each represents a hydrogen atom or Represents a saturated or unsaturated hydrocarbon group having 1 to 50 carbon atoms
- EO represents an ethylene oxide chain
- PO represents a propylene oxide chain
- n1, m1, n2, m2 represent the average number of added moles
- At least one of the R1a and the R2a is a saturated or unsaturated hydrocarbon group having 1 to 50 carbon atoms.
- At least one of an ether compound (A) and an ester compound (B) in which at least one of R1b and R2b is a saturated or unsaturated hydrocarbon group having 1 or more and 50 or less carbon atoms. May contain. According to the bulking agent for a fiber-mixed board of this form, the bulkiness of the fiber-mixed board as a building material board can be further improved.
- a bulking agent for a fiber-mixed board as a building material board is provided.
- This bulking agent for fiber-mixed boards is a bulking agent used for fiber-mixed boards as building material boards containing cement and pulp, and is an ether compound of the following general formula (1) or an ester compound of the following general formula (2). It is characterized by containing at least one of these. According to the bulking agent for a fiber-mixed board of this form, the bulkiness of the fiber-mixed board as a building material board can be improved.
- R1 and R2 are the same or different and each represents a hydrogen atom or an alkyl group having 1 to 50 carbon atoms
- EO represents an ethylene oxide chain

Description
本発明は、建材ボードとしての繊維混入板用嵩高剤に関する。本出願は、２０２２年８月２３日に出願された日本国特許出願第２０２２－１３２２３５号に基づくもので、ここにその記載内容を援用する。
The present invention relates to a bulking agent for a fiber-mixed board as a building material board. This application is based on Japanese Patent Application No. 2022-132235 filed on August 23, 2022, and the contents thereof are incorporated herein.
近年、建材ボードとしての繊維混入板において、材料価格の高騰、環境保護の必要性および資源の有効利用等の観点から、嵩高さに重要なパルプの使用量を減らしつつも、建材ボードにおける繊維混入板の厚みを維持することが望まれている。
In recent years, from the viewpoint of rising material prices, the need for environmental protection, and the effective use of resources, the use of pulp, which is important for bulkiness, has been reduced in fiber-mixed boards used as building material boards. It is desired to maintain the thickness of the board.
製紙の分野で用いられるパルプ嵩高剤としては、高級アルコールや、そのアルキレンオキシド付加物を含有する紙用嵩高剤(特許文献１)、油脂または糖アルコール系非イオン界面活性剤を含有する紙用嵩高剤(特許文献２)、脂肪酸のアルキレンオキシド付加物を含有する紙用嵩高剤(特許文献３)、カチオン性化合物、アミン、アミンの酸塩、両性化合物を含有する紙用嵩高剤(特許文献４)、更には多価アルコール脂肪酸エステルの紙用嵩高剤(特許文献５)や、脂肪族カルボン酸とポリアミンから得られる化合物にエピハロヒドリンを反応して得られる化合物を含有する紙用嵩高剤(特許文献６)が知られている。
Pulp bulking agents used in the paper manufacturing field include paper bulking agents containing higher alcohols and their alkylene oxide adducts (Patent Document 1), and paper bulking agents containing oils and fats or sugar alcohol-based nonionic surfactants. paper bulking agents containing alkylene oxide adducts of fatty acids (Patent Document 3), paper bulking agents containing cationic compounds, amines, acid salts of amines, and amphoteric compounds (Patent Document 4) ), paper bulking agents containing polyhydric alcohol fatty acid esters (Patent Document 5), and paper bulking agents containing compounds obtained by reacting epihalohydrin with compounds obtained from aliphatic carboxylic acids and polyamines (Patent Document 5). 6) is known.
特許文献７には、嵩高な無機質板の製造方法として、スラリーにアルコキシシラン類を添加し、混合撹拌で発泡を促して微細気泡を含ませる方法が開示されている。
Patent Document 7 discloses, as a method for manufacturing a bulky inorganic plate, a method in which alkoxysilanes are added to a slurry, and foaming is promoted by mixing and stirring to include fine bubbles.
特許文献１～６に記載の紙用嵩高剤は、酸性～中性のスラリーに添加される。このため、スラリーの液性が強アルカリ性である繊維混入板においては、十分な嵩高効果が得られないことを本願発明者らは見出した。また、繊維混入板のスラリーは、カルシウムイオン濃度が極めて高い。このため、カルシウムイオン濃度が高くない対象物に適用される紙用嵩高剤を繊維混入板に用いても、十分な嵩高効果が得られないことを本願発明者らは見出した。
The paper bulking agents described in Patent Documents 1 to 6 are added to acidic to neutral slurries. For this reason, the inventors of the present invention have found that a sufficient bulking effect cannot be obtained in a fiber-mixed board in which the slurry has strong alkaline liquid properties. Further, the slurry of the fiber-mixed board has an extremely high concentration of calcium ions. For this reason, the inventors of the present invention have found that even if a paper bulking agent applied to objects that do not have a high calcium ion concentration is used in a fiber-containing board, a sufficient bulking effect cannot be obtained.
また、特許文献７に記載の方法では、混合撹拌時の泡立ちの制御が必要であるため、品質の安定した繊維混入板の製造が困難となるおそれがあり、その結果、安定した嵩高効果が得られないことを本願発明者らは見出した。加えて、特許文献７に記載の方法では、気泡の混入により加圧成型時に水走りが生じて成型材に切れが生じるおそれがあり、繊維混入板の品質を損なうおそれがある。
In addition, in the method described in Patent Document 7, since it is necessary to control foaming during mixing and stirring, it may be difficult to manufacture a fiber-mixed board with stable quality, and as a result, a stable bulking effect cannot be obtained. The inventors of the present invention have found that this is not possible. In addition, in the method described in Patent Document 7, water running may occur during pressure molding due to the inclusion of air bubbles, which may cause breaks in the molded material, which may impair the quality of the fiber-containing board.
特許文献１～６に記載の紙用嵩高剤は、酸性～中性のスラリーに添加される。このため、スラリーの液性がアルカリ性であることも多い窯業サイディングボードにおいては、十分な嵩高効果が得られないことを本願発明者らは見出した。このため、建材ボードにおける繊維混入板の嵩高性を向上させる技術が望まれる。
The paper bulking agents described in Patent Documents 1 to 6 are added to acidic to neutral slurries. For this reason, the inventors of the present invention have discovered that a sufficient bulking effect cannot be obtained in ceramic siding boards whose slurry is often alkaline. For this reason, a technique is desired that improves the bulkiness of fiber-mixed boards in building material boards.
