Description
本発明は、ポリカーボネート樹脂シートに透明性、耐擦傷性、耐候性、耐薬品性及び耐折曲げ性に優れ、反りの小さい紫外線硬化型樹脂被覆用組成物を塗布後、硬化させて、硬化皮膜を形成させてなるポリカーボネート樹脂積層体及びその製造方法に関するものである。 The present invention is a cured film obtained by applying a UV curable resin coating composition having excellent transparency, scratch resistance, weather resistance, chemical resistance and bending resistance to a polycarbonate resin sheet, and having a small warpage, followed by curing. It is related with the polycarbonate resin laminated body formed by forming and its manufacturing method.
ポリカーボネート樹脂成形品は、軽さや加工のしやすさなどの種々の特性からガラスに代わる材料として、建物の採光材や車両の窓用、計器カバー等に用いられている。しかしながら、ガラスと比較して耐擦傷性、耐薬品性、及び耐候性等の表面特性に劣る。そこで、ポリカーボネート基材の表面を改質する方法として、例えば、(i)溶剤のような非反応性で揮発性の成分をほとんど含まない紫外線硬化コーティング組成物を熱可塑性樹脂基材の表面に塗布し、(ii)未硬化のコーティング組成物と基材表面とを90〜150°Fから選択された温度に加熱して、未硬化のコーティング組成物の一部を熱可塑性樹脂基材の表面下のある領域中に浸透させて表面下に熱可塑性樹脂基材とコーティング組成物の両方を含むコーティング組成物浸透領域を形成させ、(iii)こうして塗布したコーティング組成物を、コーティング組成物と浸透領域中に紫外線を当てることによって紫外線で硬化させることからなる。コーティング組成物の紫外線硬化の際に熱可塑性樹脂基材の表面下の浸透領域は基材と硬化したコーティングとの間の噛み合い結合を提供することが記載されている(特許文献1)。しかしながら、この方法ではコーティング組成物が熱可塑性樹脂基材に浸透しすぎるため、ポリカーボネート樹脂が本来有する耐衝撃性や耐折曲げ性が損なわれ、さらには反りが大きくなる。 Polycarbonate resin molded products are used for building lighting materials, vehicle windows, instrument covers, and the like as materials to replace glass due to various characteristics such as lightness and ease of processing. However, it is inferior in surface properties such as scratch resistance, chemical resistance, and weather resistance as compared with glass. Therefore, as a method for modifying the surface of the polycarbonate substrate, for example, (i) an ultraviolet curable coating composition containing almost no volatile components such as a solvent is applied to the surface of the thermoplastic resin substrate. And (ii) heating the uncured coating composition and the substrate surface to a temperature selected from 90 to 150 ° F., so that a portion of the uncured coating composition is below the surface of the thermoplastic resin substrate. A coating composition penetration region comprising both the thermoplastic resin substrate and the coating composition under the surface, and (iii) the coating composition thus applied is applied to the coating composition and the penetration region. It consists of curing with ultraviolet light by applying ultraviolet light inside. It is described that the penetration area below the surface of a thermoplastic resin substrate provides an intermeshing bond between the substrate and the cured coating during UV curing of the coating composition (Patent Document 1). However, in this method, since the coating composition penetrates too much into the thermoplastic resin substrate, the impact resistance and the bending resistance inherent in the polycarbonate resin are impaired, and the warpage increases.
耐候性、耐擦傷性、及び密着力に優れ、かつ表面欠陥の少ないポリカーボネート樹脂成形品として、(A)1,4−ブタンジオールジ(メタ)アクリレート及び1,6−ヘキサンジオールジ(メタ)アクリレートの少なくとも一種を必須成分とする、分子中に2個以上のアクリロイルオキシ基またはメタクリロイルオキシ基を有する架橋重合性化合物(a−1)と、該化合物(a−1)と共重合可能な他の化合物(a−2)とからなる光重合性組成物、(B)365〜400nm増感波長のピークを有する特定の光重合開始剤(b−1)を含む光重合開始剤、および(C)紫外線吸収剤を主成分として含有してなる紫外線硬化型樹脂被覆用組成物で被覆したポリカーボネート樹脂成形品の製法が知られていた(特許文献2)。しかしながら、この文献に開示されている紫外線硬化型樹脂被覆用組成物では、ポリカーボネート樹脂シートの製造時に同時に硬化皮膜で被覆されたポリカーボネート樹脂積層体を製造するには、該紫外線硬化型樹脂被覆用組成物では、高温で粘度が低下するため、均一な硬化皮膜を得ることが困難であるばかりか、該紫外線硬化型樹脂被覆用組成物がポリカーボネート樹脂シートに浸透しすぎるため、ポリカーボネート樹脂が本来有する耐衝撃性や耐折曲げ性が損なわれ、反りが大きくなるという問題があり、さらに、該紫外線硬化型樹脂被覆用組成物を使用するためには、ポリカーボネートシートを室温近くまで冷却する必要があり、ポリカーボネート樹脂シートを製造する押出機から、該紫外線硬化型樹脂被覆用組成物を塗布するまでの距離が十数メートルも必要であった。 (A) 1,4-butanediol di (meth) acrylate and 1,6-hexanediol di (meth) acrylate as polycarbonate resin molded products having excellent weather resistance, scratch resistance and adhesion, and few surface defects A cross-linkable polymerizable compound (a-1) having two or more acryloyloxy groups or methacryloyloxy groups in the molecule and at least one of the above as an essential component, and other compounds copolymerizable with the compound (a-1) A photopolymerizable composition comprising the compound (a-2), (B) a photopolymerization initiator containing a specific photopolymerization initiator (b-1) having a peak of 365 to 400 nm sensitization wavelength, and (C) There has been known a method for producing a polycarbonate resin molded article coated with an ultraviolet curable resin coating composition containing an ultraviolet absorbent as a main component (Patent Document 2). However, in the ultraviolet curable resin coating composition disclosed in this document, in order to produce a polycarbonate resin laminate coated with a cured film at the same time as the production of the polycarbonate resin sheet, the ultraviolet curable resin coating composition is used. In the product, since the viscosity decreases at high temperature, it is difficult to obtain a uniform cured film, and the ultraviolet curable resin coating composition penetrates too much into the polycarbonate resin sheet. There is a problem that impact resistance and bending resistance are impaired and warping increases, and in addition, in order to use the composition for coating an ultraviolet curable resin, it is necessary to cool the polycarbonate sheet to near room temperature, From the extruder for producing the polycarbonate resin sheet to the application of the UV-curable resin coating composition The distance is several tens of meters was also necessary.
ポリカーボネート樹脂シートに被覆用組成物を塗布し、硬化皮膜を形成することにより耐擦傷性を改良した公知のポリカーボネート樹脂積層体の場合、被覆用組成物がポリカーボネート樹脂シートに浸透しすぎるため、硬化皮膜に発生したクラックが樹脂シートに伝播して、該積層体の耐衝撃性や耐折曲げ性が著しく損なわれるという問題があった。例えば、耐擦傷性の改良された厚さ0.5mmのポリカーボネート樹脂積層体からなる試験片を上180°、下180°の折曲げ試験を行うと、2回以下の折曲げで破断するような耐折曲げ性の劣る積層体であった。 In the case of a known polycarbonate resin laminate in which the coating composition is applied to the polycarbonate resin sheet and the cured film is formed to improve the scratch resistance, the coating composition is excessively permeated into the polycarbonate resin sheet. There was a problem that the cracks generated in the film propagated to the resin sheet, and the impact resistance and bending resistance of the laminate were significantly impaired. For example, when a test piece made of a polycarbonate resin laminate having a thickness of 0.5 mm with improved scratch resistance is subjected to a bending test of 180 ° above and 180 ° below, the test piece breaks when bent twice or less. The laminate was inferior in bending resistance.
本発明は、上記諸問題を解決し、透明性、耐擦傷性、耐候性、耐薬品性のみならず耐折曲げ性に優れ、反りが小さく、高温のポリカーボネート樹脂シートに塗布が可能な紫外線硬化型樹脂組成物を開発し、さらに、ポリカーボネート樹脂シートの製造時に、樹脂シート上に硬化皮膜を形成したポリカーボネート樹脂積層体及び該積層体の製造方法を提供することである。 The present invention solves the above-mentioned problems and is not only transparent, scratch resistant, weather resistant, chemical resistant but also has excellent bending resistance, small warpage, and UV curing that can be applied to a high-temperature polycarbonate resin sheet. A mold resin composition is developed, and a polycarbonate resin laminate in which a cured film is formed on the resin sheet at the time of production of the polycarbonate resin sheet and a method for producing the laminate are provided.
本発明者らは、上記課題を解決するために鋭意検討した結果、表面温度70〜90℃であるポリカーボネート樹脂シート上に紫外線硬化型樹脂被覆用組成物を塗布しても、ポリカーボネート樹脂への過度の浸透が起こらない紫外線硬化型樹脂被覆用組成物を見出し、さらに、該被覆用組成物からなる硬化皮膜で被覆されたポリカーボネート樹脂積層体は、透明性、耐擦傷性、耐候性及び耐薬品性のみならず、耐折曲げ性にも著しく優れ、反りも小さいことを見出し、本発明を完成させた。すなわち、本発明の要旨は、プロピレンオキサイド変性ネオペンチルグリコールジアクリレート(A)20〜70重量%と、重量平均分子量400以上の2〜4官能のアクリレートオリゴマ−(B)80〜30重量%からなる光重合性組成物(C)100重量部に対し、光重合開始剤(D)を1〜10重量部配合してなる紫外線硬化型樹脂被覆用組成物(E)を、ポリカーボネート樹脂シート(F)の少なくとも一方の面に塗布後、硬化させ、硬化皮膜を形成させてなる耐折曲げ性に優れたポリカーボネート樹脂積層体(G)及びその製造方法である。 As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that even if the composition for coating an ultraviolet curable resin is applied on a polycarbonate resin sheet having a surface temperature of 70 to 90 ° C., excessive application to the polycarbonate resin is not possible. A UV-curable resin coating composition that does not permeate water is found, and a polycarbonate resin laminate coated with a cured film made of the coating composition has transparency, scratch resistance, weather resistance, and chemical resistance. In addition, the inventors have found that the bending resistance is remarkably excellent and the warpage is small, and the present invention has been completed. That is, the gist of the present invention consists of 20 to 70% by weight of propylene oxide-modified neopentyl glycol diacrylate (A) and 80 to 30% by weight of a bi- and tetrafunctional acrylate oligomer (B) having a weight average molecular weight of 400 or more.

The compounding quantity of a reactive diluent (H) is 15-70 weight part with respect to 100 weight part of acrylate oligomer (B). When the amount of the reactive diluent (H) is less than 15 parts by weight, the viscosity of the UV-curable resin coating composition (E) is too high, and when it exceeds 70 parts by weight, the cured film is less warped or folded.

When the component (A) is less than 20% by weight in the photopolymerizable composition (C), the viscosity of the photopolymerizable composition (C) becomes too high and the adhesion of the coating film is lowered. Further, if the component (A) exceeds 70% by weight in the photopolymerizable composition (C), the viscosity of the photopolymerizable composition (C) becomes too low and optical distortion tends to occur, which is not preferable. Moreover, the usage-amount of a photoinitiator (D) is 1-10 weight part with respect to 100 weight part of photopolymerizable compositions (C), Preferably it is 3-6 weight part. When the amount is more than 10 parts by weight, the cured film is colored. When the amount is less than 1 part by weight, a sufficient cured film cannot be obtained.

A polymer produced by a known method is used, and a structural unit having an ester bond including a structural unit derived from a fatty acid diol may be included in the polymer skeleton. A polycarbonate resin derived from 2,2-bis (4-hydroxyphenyl) propane is preferred. Although there is no restriction | limiting in particular about molecular weight, From a viewpoint of a moldability or mechanical strength, a viscosity average molecular weight is 17,000-40,000, More preferably, it is a thing of 20,000-30,000. And this invention is implemented when manufacturing a sheet | seat by an extrusion method using this polycarbonate resin. The thickness of the polycarbonate resin sheet is 0.1 to 20 mm, preferably 0.2 to 10 mm, and more preferably 0.3 to 5 mm.
本発明において、上記紫外線硬化型樹脂被覆用組成物(E)を被覆したポリカーボネート樹脂積層体(G)を得るには、スプレー、浸漬、カーテンフロー、ロールコーティング等公知の方法を用いて塗布した後、低圧水銀灯、中圧水銀灯、高圧水銀灯、超高圧水銀灯、キセノンランプ、ガリウムランプ、メタルハライドランプ等の紫外線を照射することによって速やかに硬化させることもできるが、次のような方法が好ましい。すなわち、本発明の紫外線硬化型樹脂被覆用組成物(E)を70〜90℃の表面温度のポリカーボネート樹脂シート(F)と合成樹脂フィルム(J)との間に挟み込み、圧着後、該紫外線硬化型樹脂被覆用組成物(E)に紫外線を照射し、硬化後、合成樹脂フィルム(J)を硬化皮膜から剥離させる方法である。 In the present invention, in order to obtain the polycarbonate resin laminate (G) coated with the ultraviolet curable resin coating composition (E), it is applied using a known method such as spraying, dipping, curtain flow, roll coating, or the like. It is possible to cure quickly by irradiating with ultraviolet rays such as low pressure mercury lamp, medium pressure mercury lamp, high pressure mercury lamp, ultra high pressure mercury lamp, xenon lamp, gallium lamp, metal halide lamp, etc., but the following method is preferred. That is, the ultraviolet curable resin coating composition (E) of the present invention is sandwiched between a polycarbonate resin sheet (F) having a surface temperature of 70 to 90 ° C. and a synthetic resin film (J). In this method, the composition resin coating composition (E) is irradiated with ultraviolet rays and cured, and then the synthetic resin film (J) is peeled off from the cured film.
このようにして被覆される硬化塗膜の厚みは1〜15μm、好ましくは2〜10μmである。硬化皮膜の厚さが1μm未満では十分な耐候性や耐擦傷性を得るのが難しく、15μmを越えると密着性やコストの点から好ましくない。 The thickness of the cured coating film thus coated is 1 to 15 μm, preferably 2 to 10 μm. When the thickness of the cured film is less than 1 μm, it is difficult to obtain sufficient weather resistance and scratch resistance, and when it exceeds 15 μm, it is not preferable from the viewpoint of adhesion and cost.
紫外線硬化型樹脂被覆用組成物(E)をポリカーボネート樹脂シート(F)と合成樹脂フィルム(J)との間に挟み込む際に使用される合成樹脂フィルム(J)は、紫外線硬化型樹脂被覆用組成物(E)と親和性のないことが必須条件であり、合成樹脂フィルム(J)の表面が被膜の表面を形成するため、表面の微細な平滑性が要求される場合などには、特にフィルムの選択には注意を要する。一般的にはポリエチレンテレフタレート(PET)フィルム等を用いることができる。合成樹脂フィルムの厚さは、10〜200μmが好ましく、10μm未満では合成樹脂フィルムにしわがよりやすく、200μmを越えると硬化皮膜の厚み調整が困難になる。 The synthetic resin film (J) used when the ultraviolet curable resin coating composition (E) is sandwiched between the polycarbonate resin sheet (F) and the synthetic resin film (J) is an ultraviolet curable resin coating composition. It is an essential condition that it has no affinity with the product (E), and since the surface of the synthetic resin film (J) forms the surface of the coating, the film is particularly necessary when fine smoothness of the surface is required. Care must be taken in selecting this. In general, a polyethylene terephthalate (PET) film or the like can be used. The thickness of the synthetic resin film is preferably 10 to 200 μm, and if it is less than 10 μm, the synthetic resin film is more likely to be wrinkled, and if it exceeds 200 μm, it is difficult to adjust the thickness of the cured film.
合成樹脂フィルム(J)とポリカーボネート樹脂シート(F)の間に被覆用組成物をはさみ込み圧着させる方法としては、プレスロール、しごき棒、ハケ、ヘラなどを用いて被膜の膜厚が均一になるように圧着できれば、いかなる方法を用いてもよい。 As a method of sandwiching the coating composition between the synthetic resin film (J) and the polycarbonate resin sheet (F) and press-bonding, the film thickness of the coating becomes uniform using a press roll, a squeezing bar, a brush, a spatula, etc. Any method may be used as long as it can be crimped.
本発明で使用される紫外線硬化型樹脂被覆用組成物は、ポリカーボネート樹脂シートへの過度の浸透が起こらないので、該被覆用組成物からなる硬化皮膜で被覆されたポリカーボネート樹脂積層体は、透明性、耐擦傷性、耐候性、耐薬品性のみならず耐折曲げ性にも著しく優れ、反りも小さいので、曲げ加工の施される用途や長時間曲げ歪みの加わる用途、高度の寸法精度の要求される用途に好適に使用できる。 Since the ultraviolet curable resin coating composition used in the present invention does not excessively penetrate the polycarbonate resin sheet, the polycarbonate resin laminate coated with the cured film made of the coating composition is transparent. , Not only scratch resistance, weather resistance, chemical resistance, but also excellent bending resistance and low warpage, so bending applications, applications where bending strain is applied for a long time, and high dimensional accuracy requirements It can be suitably used for the intended use.
