Description
本発明は、例えば台所の流し台のトップやシンク、洗面台のトップ、洗面ボウル、浴槽、浴室のカウンター等に用いられる耐衝撃性に優れた強化アクリル系人造大理石とその製造法に関するものである。
The present invention relates to reinforced acrylic artificial marble having excellent impact resistance used for, for example, kitchen sink tops and sinks, wash basin tops, wash basins, bathtubs, bathroom counters, etc., and a method for producing the same.
上記のような用途に用いられる人造大理石製品は、例えばメタクリル酸メチルにメタクリル樹脂を溶解したシラップに水酸化アルミニウム微粉体等の無機質フィラー微粉体及び硬化剤を混合した配合物を金型に注入し、加熱加圧硬化させる方法が一般的に行われている。
For artificial marble products used for the above purposes, for example, a mixture of inorganic filler fine powder such as aluminum hydroxide fine powder and a curing agent mixed with syrup in which methacrylic resin is dissolved in methyl methacrylate is injected into a mold. , A method of heating, pressure and curing is generally performed.
しかしながら、人造大理石製品を得るに当たって、耐衝撃性を高めるために補強材としてガラス繊維を０．１～３０重量部を添加することが一般的に行われている。しかし、ガラス繊維を添加することにより混合物の粘度が高くなり、攪拌時に気泡の巻き込み現象が生じ、切削加工性も劣るという欠点があった。
However, in obtaining an artificial marble product, it is common practice to add 0.1 to 30 parts by weight of glass fiber as a reinforcing material in order to enhance impact resistance. However, the addition of glass fiber has a drawback that the viscosity of the mixture is increased, a phenomenon of air bubbles being entrained during stirring occurs, and the machinability is also inferior.
本発明は、ガラス繊維を添加せずに耐衝撃性が強く、気泡の巻き込みが少ない、加工性の良い強化アクリル系人造大理石とその製造法を提案するものである。
The present invention proposes a reinforced acrylic artificial marble having strong impact resistance without adding glass fibers, less entrainment of air bubbles, and good workability, and a method for producing the same.
本発明は、メタクリル酸メチルにメタクリル樹脂を溶解したシラップにポリロタキサン及び無機質フィラー微粉体からなる配合物に硬化剤を添加して重合してなる強化アクリル系人造大理石に関するものである。
The present invention relates to a reinforced acrylic artificial marble obtained by polymerizing a mixture of polyrotaxane and fine powder of an inorganic filler in a syrup in which a methacrylic resin is dissolved in methyl methacrylate by adding a curing agent.
本発明による強化アクリル系人造大理石の製造方法の一例を述べれば、メタクリル酸メチルにメタクリル樹脂を配合してシラップを作り、これにポリロタキサン及び無機質フィラー微粉体を混合した配合物に硬化剤を添加し、これを金型に注入し、加熱加圧して重合硬化させる。
To describe an example of the method for producing reinforced acrylic artificial marble according to the present invention, methyl methacrylate is mixed with a methacrylic resin to form a syrup, and a curing agent is added to a mixture of polyrotaxane and fine powder of an inorganic filler. , This is injected into a mold and heated and pressurized to polymerize and cure.
これにより、耐衝撃性が強く、気泡の巻き込みが少ない、加工性の良好な強化アクリル系人造大理石を製造することができる。
This makes it possible to manufacture reinforced acrylic artificial marble with strong impact resistance, less air bubbles entrainment, and good workability.
ここに、ポリロタキサンとは、直鎖状のポリエチレングリコールが環状をなす分子であるシクロデキストリンを貫通し、その両端に該環状分子が脱離しないように封鎖基である嵩高いアダマンタンを配置して閉じ込めた分子形態であり、シクロデキストリンの水酸基の少なくとも一部が２－ヒドロキシプロピル基によって修飾され、該２－ヒドキシプロピル基の水酸基がポリカプロラクトン基によって修飾され、さらに該ポリカプロラクトン基末端の一部がメタクリル基、又はアクリル基によって修飾される。
Here, polyrotaxane penetrates cyclodextrin, which is a molecule in which linear polyethylene glycol forms a ring, and bulky adamantan, which is a blocking group, is arranged and confined at both ends of the cyclodextrin so that the cyclic molecule does not desorb. In this molecular form, at least a part of the hydroxyl group of cyclodextrin is modified with a 2-hydroxypropyl group, the hydroxyl group of the 2-hydroxypropyl group is modified with a polycaprolactone group, and a part of the terminal of the polycaprolactone group. Is modified with a methacryl group or an acrylic group.
上記の修飾基により、ポリロタキサンがメタクリル酸メチル及びメタクリル樹脂を溶解したシラップに高い溶解性を示す。上記ポリロタキサンは、例えば、市販されているものを使用することができ、国際公開ＷＯ２０１１／１０５５３２公報に記載されている方法を参考に作製することもできる。
Due to the above-mentioned modifying group, polyrotaxane exhibits high solubility in syrup in which methyl methacrylate and methacrylic resin are dissolved. As the polyrotaxane, for example, a commercially available one can be used, and it can also be prepared by referring to the method described in International Publication WO2011 / 105532.
ポリロタキサンを含有するシラップの配合割合は、前記シラップ１００重量部に対し０．２～１０重量部が好適である。０．２重量部未満では耐衝撃性の向上が極めて小さく、また１０重量部を超えても大きな耐衝撃性の向上は見られない。
The blending ratio of the syrup containing polyrotaxane is preferably 0.2 to 10 parts by weight with respect to 100 parts by weight of the syrup. If it is less than 0.2 parts by weight, the improvement in impact resistance is extremely small, and if it exceeds 10 parts by weight, no significant improvement in impact resistance is observed.
また、ここでいう無機質フィラー微粉体とは、水酸化アルミニウム微粉体、シリカ微粉体、水酸化マグネシウム微粉体、石膏微粉体、ガラス微粉体、炭酸カルシウム微粉体、タルク微粉体等の単体又はその混合体であるが、特に水酸化アルミニウム微粉体、シリカ微粉体、ガラス微粉体、炭酸カルシウム微粉体の単体又はその混合体が好ましい。
Further, the inorganic filler fine powder referred to here is a simple substance such as aluminum hydroxide fine powder, silica fine powder, magnesium hydroxide fine powder, gypsum fine powder, glass fine powder, calcium carbonate fine powder, talc fine powder, or a mixture thereof. As for the body, aluminum hydroxide fine powder, silica fine powder, glass fine powder, calcium carbonate fine powder alone or a mixture thereof are particularly preferable.
無機質フィラー微粉体の配合割合は、メタクリル酸メチルにメタクリル樹脂を溶解したシラップ１００重量部に対して、４０～４００重量部が好適である。この範囲外では、天然の大理石の美麗な外観のイメージを呈することはできない。
The blending ratio of the inorganic filler fine powder is preferably 40 to 400 parts by weight with respect to 100 parts by weight of syrup in which a methacrylic resin is dissolved in methyl methacrylate. Outside this range, it is not possible to give an image of the beautiful appearance of natural marble.
また、硬化剤は、適宜の量を用い、例えば２－２アゾビスイソブチロニトリル、ベンゾイルパーオキサイド、ジイソプロピルパーオキシカーボネート、ジー２－エチルヘキシルパーオキシカーボネート、ジーｎ－プロピルパーオキシジカーボネート、ジミリスチルパーオキシジカーボネート、ビス（４－ｔ－ブチルジシクロヘキシル）パーオキシカーボネート等のうちの少なくとも１種以上を使用する。
また、使用される金型は、金属製、木製、プラスチック製等の注型用やプレス用の金型あるいは金属ベルト状の金型である。 Further, the curing agent is used in an appropriate amount, for example, 2-2 azobisisobutyronitrile, benzoyl peroxide, diisopropyl peroxy carbonate, di-2-ethylhexyl peroxy carbonate, di n-propyl peroxy dicarbonate, di. At least one of myristyl peroxydicarbonate, bis (4-t-butyldicyclohexyl) peroxycarbonate and the like is used.
