Description

【0001】
【産業上の利用分野】
本発明はトリアジン環含有(メタ)アクリレートプレポリマー系樹脂組成物とこれを使用した化粧版及びその製法に関するものである。
【0002】
【従来の技術】
従来、トリアジン環を持つ樹脂、例えばメラミンホルムアルデヒド樹脂は高硬度、耐熱性、あるいは絶縁性等の特性を生かして化粧板、塗料、成形材料等の分野において利用されてきた。しかしながら得られた樹脂は溶媒を含むため乾燥工程が必要であり、かつまた加熱・加圧時に縮合反応にともないガスが発生する等の問題があつた。
また、特に耐酸性を要する特殊に用途例えば実験台天板等には使用が難しい。耐候性についてもまだ不十分な点があり室内用途に限られる等の課題がのこされていた。
【0003】
【発明が解決しようとする課題】
本発明は無溶媒下において成形加工が可能であり、特に耐薬品性を要求される分野での使用が難しい、耐候性に難点があり室内用途に限られる等の課題を解決せんとするものである。
【0004】
【課題を解決するための手段】
本発明においてはアミノトリアジン(以下AZという)、ホルムアルデヒド好ましくはパラホルムアルデヒド(以下Pという)及びヒドロキシエチル(メタ)アクリレート(以下HAという)から合成されるトリアジン環含有(メタ)アクリレートプレポリマー(以下TAという)とイソシアネートを含む化合物並びに未反応のHAを含む樹脂組成物を使用し、該組成物を反応させてハンドリング可能な固形状とし、加熱・加圧成形する製造方法により課題の品質をクリヤーした化粧板を実現したものである。
【0005】
AZとは炭素、窒素からなるトリアジン環の3つの炭素原子にそれぞれアミノ基が結合した構造の化合物であり、AZとはAZ自身あるいはAZ誘導体を示す。AZ自身としてはメラミンが挙げられ、AZ誘導体としてはベンゾグアナミン、アセトグアナミン、シクロヘキサンカルボグアナミン、シクロヘキサンカルボグアナミン、ノルボルネンカルボグアナミン、等が挙げられる。
【0006】
Pは常温で固体であつて、本発明ではAZとともにヒドロキシ(メタ)アクリレートに溶解して用いることができ、37%ホルムアルデヒト゛水溶液を用いた場合と比較し、基本的に脱水、脱溶媒の工程が不要となる利点がある。
【0007】
HAとはアクリレートをベースとした2−ヒドロキシエチルアクリレート、エチルメタアクリレートをベースとする2−ヒドロキシエチルメタアクリレートがふくまれ、本発明においては各々の単独使用と両者の併用ができる。
【0008】
HAのほかに、必要に応じて少なくとも1個のヒドロキシル基を持つエチレン性不飽和結合を有する化合物、例えば2−ヒドロキシプロピル(メタ)アクリレート、ポリエチレングリコールモノ(メタ)アクリレート、トリメチロールプロパンモノ(メタ)アクリレート、トリメチルプロパンジ(メタ)アクリレート、アリルアルコール、N−メチロール(メタ)アクリルアミド等あるいはこれらの混合物が使用できる。
【0009】
プレポリマーの合成
本発明のTAはAZとPにより導入されたメチロール基とHA中の水酸基との反応により脱水縮合エーテル化されたもの、あるいはPとHAとの反応により導入されたメチロール基とAZとの反応により脱水縮合エーテル化されたものと解される。
【0010】
プレポリマーの合成においてHA中にAZとPを溶解させれば反応を進めることができる。場合により粘度調整等のため溶剤、例えばアルコール、トルエン等を適当量配合し、反応させることもできる。
【0011】
これら配合物の配合比はAZとしてメラミンを使用し、無溶剤下で反応を進めた場合、メラミンとPの配合モル比は1対2以上が好ましくまた、メラミンとHAとの配合モル比は1対2以上が好ましい。
【0012】
プレポリマーの合成反応は無触媒でも進めることができるが、AZの溶解性、エーテル化反応を促進させるため、当初カセイソーダ、炭酸ナトリウム、アンモニア、トリエチルアミン等のアルカリを配合したり、当初または反応途中においてエーテル触媒であるパラトルエンスルホン酸、塩酸等の酸を使用することもできる。
【0013】
当反応にはエチレン性不飽和結合の存在下で進めるため付加重合によりゲル化の懸念がある。このためキノン系の重合禁止剤を添加したり、酸素ガスを反応系に導入して合成反応を進めることが必要になる。またゲル化を回避して合成反応を進めるために反応温度は50〜150℃程度、好ましくは70〜130℃程度であって、反応時間としては0.5〜10時間程度が適当である。
【0014】
このようにして合成されたTAはトリアジン環に対して(メタ)アクリレート基及びアルキルエーテル基、反応条件によつてはメチロール基、アミノ基、HAを含むプレポリマーである。平均分子量は仕込み配合、反応条件等により異なるが平均分子量200〜8000程度のプレポリマーとして得られる。分子量が8000以上では高粘度となり好ましくない。また200以下では性能的に不十分なもとなる。また、イソシアネート化合物との反応を進めさせるためにHAを必要程度未反応の状態で残していることが望ましい。
【0015】
当該プレポリマーに対して配合されるイソシアネート化合物として例えば、イソシアネート単量体、アダクト体、アロファネート変性体、ビュレット変性体、イソシアヌレート変性体、カルボジイミド体、ウレタンプレポリマー等が挙げられる。これらは該TA中に含有される水酸基、メチロール基、アミノ基の活性水素と反応可能であり、反応により該TAはよりハンドリング可能な固形状態が得られる。これらイソシアーネート化合物の種類、例えば脂肪族系のイソシアネート化合物の使用により無黄変性タイプが、芳香族系では黄変タイプの特性をもつものが得られる。
【0016】
イソシアネート化合物との反応については必ずしも触媒は必要としないが、硬化法、作業性等を考慮してアミン系、有機金属触媒等が使用されてもよい。
【0017】
本発明により得られる組成物は前記のTA及びイソシアネート化合物を主成分として、これに重合触媒、硬化促進剤等が配合され、必要により充填剤、紫外線吸収剤、着色剤等が配合されて使用に供される。
【0018】
重合触媒については、例示すれば有機過酸化物、アゾ系化合物等が使用される。
【0019】
このように調製された配合物は紙あるいは合繊、ガラス繊維等から加工された不織布、マツト等を基材としてこれらにコートもしくは含浸あるいは繊維チョップ等を加えシート状としたのち、組成物中の水酸基あるいは及びメチロール基、アミノ基とイソシアネート基を反応させてハンドリング可能なプリプレグシートを得る。
【0020】
これらブリプレグシートを単独または複数枚重ねて熱圧成形して樹脂をフローさせ、TA中の不飽和基を重合せしめ成形板を得る。
【0021】
【実施例】
攪拌装置、温度計、気体吹き込み管を備えたセパラブルフラスコに2−ヒドロキシメタアクリレート781部(6モル)、メラミン126(1モル)、95%P189g(6モル)を加え昇温した。メラミン及びP が2−ヒドロキシメタアクリレートに溶解したのち、ハ゜ラトルエンスルホン酸3.0gを加え、内温を90〜120℃に保ち、空気を吹き込みながら反応させ、未反応の2−ヒドロキシメタアクリレート含有量が40%になるまで反応した。得られた水酸基並びに重合性の不飽和結合を持つTAは20℃での粘度が1000mPa・sec、臭素価が92.1であった。以上で得られたTAを用い表1の配合にて硬化性組成物を得た。

【発明の効果】
本発明になる組成物はトリアジン環含有(メタ)アクリレートプレポリマーにイソシアネート化合物が配合されたものであつて、該組成物を不織布等の基材に含浸もしくは塗布させたのち、反応させてハンドリング可能なプリプリレグ状としたのち、熱圧させれば容易に化粧板等に成形されるものであるが、溶媒を含まない組成物であるため乾燥が不要であり、しかも成形時に縮合水等の発生ガスがなく成形時にガス抜き等の作業が不要であり、成形に至る工程を簡略化できる。また、該組成物を使用した成型物はトリアジン環骨格がアクリレート部分を介してイソシアネートで架橋した構造をもつためメラミン樹脂の持つ硬度、耐熱性等の特徴に加えて耐薬品性、耐候性、耐煮沸性等に優れた性能を持つ成形物が得られ、殊に耐酸性については他の樹脂では得られない性能を持つため実験台天板等には最適である。[0001]
[Industrial application fields]
The present invention relates to a triazine ring-containing (meth) acrylate prepolymer resin composition, a decorative plate using the same, and a method for producing the same.
[0002]
[Prior art]
Conventionally, resins having a triazine ring, such as melamine formaldehyde resins, have been used in the fields of decorative plates, paints, molding materials and the like by taking advantage of properties such as high hardness, heat resistance, and insulation. However, since the obtained resin contains a solvent, a drying step is required, and there is a problem that gas is generated due to the condensation reaction during heating and pressurization.
In addition, it is difficult to use for special applications that require acid resistance, such as an experimental bench top. The weather resistance was still insufficient and there were problems such as being limited to indoor use.
[0003]
[Problems to be solved by the invention]
The present invention can be processed in the absence of a solvent and solves problems such as difficulty in use in fields requiring chemical resistance, difficulty in weather resistance, and limited to indoor use. is there.
[0004]
[Means for Solving the Problems]
In the present invention, a triazine ring-containing (meth) acrylate prepolymer (hereinafter referred to as TA) synthesized from aminotriazine (hereinafter referred to as AZ), formaldehyde, preferably paraformaldehyde (hereinafter referred to as P) and hydroxyethyl (meth) acrylate (hereinafter referred to as HA). And a resin composition containing an isocyanate-containing compound and unreacted HA, the composition is reacted to form a solid that can be handled, and the quality of the problem is cleared by a manufacturing method of heating and pressure molding. A decorative board is realized.
[0005]
AZ is a compound having a structure in which an amino group is bonded to each of three carbon atoms of a triazine ring composed of carbon and nitrogen, and AZ represents AZ itself or an AZ derivative. Examples of AZ itself include melamine, and examples of AZ derivatives include benzoguanamine, acetoguanamine, cyclohexanecarboguanamine, cyclohexanecarboguanamine, norbornenecarboguanamine, and the like.
[0006]
P is a solid at room temperature, and can be used by being dissolved in hydroxy (meth) acrylate together with AZ in the present invention. Compared with the case where 37% formaldehyde aqueous solution is used, the steps of dehydration and desolvation are basically different. There is an advantage that becomes unnecessary.
[0007]
HA includes 2-hydroxyethyl acrylate based on acrylate and 2-hydroxyethyl methacrylate based on ethyl methacrylate. In the present invention, each can be used alone or in combination.
[0008]
In addition to HA, if necessary, a compound having an ethylenically unsaturated bond having at least one hydroxyl group, such as 2-hydroxypropyl (meth) acrylate, polyethylene glycol mono (meth) acrylate, trimethylolpropane mono (meta) ) Acrylate, trimethylpropanedi (meth) acrylate, allyl alcohol, N-methylol (meth) acrylamide, or the like, or a mixture thereof.
[0009]
Synthesis of Prepolymer TA of the present invention is a product obtained by dehydration condensation etherification by the reaction of a methylol group introduced by AZ and P and a hydroxyl group in HA, or a methylol group and AZ introduced by the reaction of P and HA. It is understood that it was dehydrated and condensed etherified by the reaction with.
[0010]
In the synthesis of the prepolymer, the reaction can proceed if AZ and P are dissolved in HA. In some cases, an appropriate amount of a solvent such as alcohol or toluene may be added and reacted to adjust the viscosity.
[0011]
When melamine is used as AZ and the reaction proceeds in the absence of a solvent, the blending ratio of these blends is preferably 1 to 2 or more, and the blending mole ratio of melamine and HA is 1 Two or more pairs are preferred.
[0012]
The synthesis reaction of the prepolymer can be carried out without a catalyst, but in order to promote the solubility of AZ and the etherification reaction, an alkali such as caustic soda, sodium carbonate, ammonia, triethylamine or the like may be added at the beginning or during the reaction. Acids such as paratoluenesulfonic acid and hydrochloric acid which are ether catalysts can also be used.
[0013]
Since this reaction proceeds in the presence of an ethylenically unsaturated bond, there is a concern of gelation by addition polymerization. Therefore, it is necessary to add a quinone-based polymerization inhibitor or introduce oxygen gas into the reaction system to advance the synthesis reaction. In order to proceed with the synthesis reaction while avoiding gelation, the reaction temperature is about 50 to 150 ° C., preferably about 70 to 130 ° C., and the reaction time is about 0.5 to 10 hours.
[0014]
TA synthesized in this way is a prepolymer containing a (meth) acrylate group and an alkyl ether group with respect to the triazine ring, and depending on the reaction conditions, a methylol group, an amino group, and HA. Although the average molecular weight varies depending on the preparation and reaction conditions, it can be obtained as a prepolymer having an average molecular weight of about 200 to 8000. A molecular weight of 8000 or more is not preferable because of high viscosity. If it is 200 or less, the performance is insufficient. Further, it is desirable to leave HA in an unreacted state to the extent necessary for the reaction with the isocyanate compound to proceed.
[0015]
As an isocyanate compound mix | blended with the said prepolymer, an isocyanate monomer, an adduct body, an allophanate modified body, a bullet modified body, an isocyanurate modified body, a carbodiimide body, a urethane prepolymer etc. are mentioned, for example. These can react with the active hydrogen of a hydroxyl group, a methylol group, or an amino group contained in the TA, and the TA can obtain a solid state that can be handled more by the reaction. By using the isocyanate compound, for example, an aliphatic isocyanate compound, a non-yellowing type can be obtained, and an aromatic type having a yellowing type can be obtained.
[0016]
A catalyst is not necessarily required for the reaction with the isocyanate compound, but an amine-based or organometallic catalyst may be used in consideration of the curing method, workability, and the like.
[0017]
The composition obtained by the present invention contains the above-mentioned TA and isocyanate compound as main components, and is blended with a polymerization catalyst, a curing accelerator, etc., and if necessary, a filler, an ultraviolet absorber, a colorant, etc. are blended. Provided.
[0018]
For the polymerization catalyst, for example, organic peroxides, azo compounds, etc. are used.
[0019]
The composition thus prepared is made of paper or synthetic fiber, non-woven fabric processed from glass fibers, mats, etc. as a base material and coated or impregnated or fiber chops are added to form a sheet, and then the hydroxyl group in the composition Alternatively, a prepreg sheet that can be handled is obtained by reacting a methylol group, an amino group, and an isocyanate group.
[0020]
A single plate or a plurality of these prepreg sheets are stacked and hot-press molded to flow the resin, and the unsaturated group in TA is polymerized to obtain a molded plate.
[0021]
【Example】
To a separable flask equipped with a stirrer, a thermometer, and a gas blowing tube, 781 parts (6 mol) of 2-hydroxymethacrylate, 126 (1 mol) of melamine and 189 g (6 mol) of 95% P were added and the temperature was raised. After melamine and P 2 are dissolved in 2-hydroxymethacrylate, add 3.0 g of toluenetoluene sulfonic acid, keep the internal temperature at 90-120 ° C. and react while blowing air, containing unreacted 2-hydroxymethacrylate The reaction was continued until the amount was 40%. The TA having a hydroxyl group and a polymerizable unsaturated bond thus obtained had a viscosity at 20 ° C. of 1000 mPa · sec and a bromine number of 92.1. A curable composition was obtained with the composition shown in Table 1 using the TA obtained above.
