Description

具有高透射率之無光防焰性物件 Light-free flame-resistant object with high transmittance

本發明係關於經塗佈之物件，其包含由透明、含阻燃物質之熱塑性聚合物製成的基材(S)、及包含在物件一側或兩側之含二氧化矽微粒之防刮塗層。本發明係也關於製備此等經塗佈物件以及其用途，特別是製造平面顯示器以及玻璃，以及關於可由其獲得之平面顯示器以及玻璃。 The present invention relates to a coated article comprising a substrate (S) made of a transparent, flame retardant-containing thermoplastic polymer, and a scratch-resistant layer containing cerium oxide particles contained on one or both sides of the article. coating. The present invention is also directed to the preparation of such coated articles and their use, particularly in the manufacture of flat panel displays and glass, as well as on flat panel displays and glass obtainable therefrom.

本發明中”顯示器”一詞係敘述含有屏幕之顯示器的前方，即用於再現圖像的透明前面板，以及任選地較佳的非透明材料所製成的周邊框架。今日顯示器主要是以平面顯示器為主流。 The term "display" in the present invention is used to describe the front of a display containing a screen, i.e., a transparent front panel for reproducing an image, and optionally a peripheral frame made of a non-transparent material. Today's displays are mainly based on flat-panel displays.

近幾年平面電視的市場有顯著地成長。除了在平面螢幕技術所取得的進展，主要是藉由製造商強烈地專注於創新的電視設計而促使這市場的成長。除其他因素外，這也可以藉由使用塑膠做為電視機外殼材料而達到其創新的設計。因此，舉例來說，近幾年可以發現越來越多使用黑色、高光澤之電視前框。近幾年較佳所使用的外殼塑膠材料已被廣泛用於電視前框以及背座。 The market for flat-panel TVs has grown significantly in recent years. In addition to the advances in flat screen technology, this is mainly driven by the strong focus of manufacturers on innovative TV designs. Among other things, this can be achieved by using plastic as the material for the TV casing. So, for example, in recent years, it has been found that more and more black, high-gloss TV front frames are used. The outer casing plastic materials that have been preferably used in recent years have been widely used in television front frames and back seats.

在電視內部，其中一個挑戰在於如何使所有產生的光盡可能地發射通過電視機無光屏幕。在此觀點下，近幾年如何將塑膠元件放至電視機中的需求已與日俱增。 Inside the TV, one of the challenges is how to make all the generated light as possible as possible through the TV's matte screen. In this view, the demand for how to put plastic components into television sets has increased in recent years.

當平面電視在市場上的強勁地增長，相同地這些電視機的安全要求也越來越高。舉例來說，參照CLC/TS 62441，EN 60065指明自2010年7月起在歐盟的平面電視所使用的外殼材料必須符合最低防焰之標準。用以改善阻燃性並結合關於此新概念之高度要求以及甚至是新穎的設計之要求的需求，將變成生產電視外殼元件之必要條件。舉例來說，有可能進一步透過改變設計而更多地採用塑料，如在無光螢幕中，到現在為止通常是用玻璃製備而得，其同時必須考慮材料特性，如透明度，透射率和阻燃性。為了得到經濟生產製程，有極大的興趣在於使用其相同的基材於框架以及螢幕顯示器。這意味著所使用的材料將符合可放置於框架以及螢幕上的需求，特別是在耐磨損性、透射率、阻燃性和黏度。 When flat-panel TVs are growing strongly in the market, the security requirements for these TV sets are also increasing. For example, with reference to CLC/TS 62441, EN 60065 indicates that the outer casing material used in flat-panel televisions in the European Union since July 2010 must meet the minimum flameproof standards. The need to improve flame retardancy combined with the high requirements of this new concept and even the requirements of novel designs will become a necessary condition for the production of TV housing components. For example, it is possible to further use plastics by changing the design, such as in matt screens, which have until now been usually made of glass, which must also take into account material properties such as transparency, transmittance and flame retardancy. Sex. In order to get an economical production process, there is great interest in using the same substrate for the frame as well as the screen display. This means that the materials used will meet the requirements of being placed on the frame as well as on the screen, especially in terms of abrasion resistance, transmission, flame retardancy and viscosity.

未塗佈基材有數個原因而無法滿意地符合使用於顯示器上的要求，特別是平面顯示器。舉例來說，如果欲同時保留良好機械性質，一方面是磨損值相對於清潔而言是過低的，另一方面是例如在電氣或電子行業(E/E)中，也需要增加阻燃性質，其僅可由少數許多市售的熱塑性聚合物達成，特別具有低的框厚度。再者，部份製造商期望得到無光、非鏡面的表面。 Uncoated substrates have several reasons that do not satisfactorily meet the requirements for use on displays, particularly flat panel displays. For example, if it is desired to retain good mechanical properties at the same time, on the one hand, the wear value is too low relative to cleaning, and on the other hand, for example in the electrical or electronic industry (E/E), it is also necessary to increase the flame retardant properties. It can only be achieved by a small number of commercially available thermoplastic polymers, in particular with a low frame thickness. Furthermore, some manufacturers expect a matte, non-specular surface.

最後，為了關於生產方面的技術原因，尤其是具有比較高的MVR值之自由流動的熱塑性塑料是感興趣的。 Finally, for the technical reasons regarding production, especially free-flowing thermoplastics with relatively high MVR values are of interest.

至目前為止，現有技術仍未提供任何解決其能夠容易地製造僅含有一基材層之物件的方案，其中要能夠同一時間滿足無光以及具有足夠的透射率之防焰物件，像可使用在顯示器螢幕之性質組合。 Until now, the prior art has not provided any solution to the problem that it can easily manufacture an article containing only one substrate layer, wherein it is possible to satisfy the matte object having no light and sufficient transmittance at the same time, such as can be used in A combination of the nature of the display screen.

令人驚奇的是，目前發現由防焰透明熱塑性聚合物所製備的基材，像是薄板、面板或薄膜，在提供了含有二氧化矽微粒之塗層後，其具有結合了優良的阻燃性質、無光表面以及良好透射率性質。 Surprisingly, it has been found that substrates prepared from flame-retardant transparent thermoplastic polymers, such as sheets, panels or films, have excellent flame retardancy after being provided with a coating containing cerium oxide particles. Properties, matte surfaces, and good transmission properties.

根據本發明中的物件，其包含了一個由透明、含阻燃物之熱塑性聚合物製成之基材(S)以及含有二氧化矽微粒之防刮塗層(K)，因此代表一種容易生產和靈活的可用以克服上述問題之解決方案。有利的是，本發明中的塗層可以在一個生產步驟中得到，例如藉由簾塗佈法。在同一時間，可以在基材的反面以保護膜進行疊層以防止劃傷，其保護膜可以例如是聚乙烯。 The article according to the present invention comprises a substrate (S) made of a transparent, flame retardant-containing thermoplastic polymer and a scratch-resistant coating (K) containing cerium oxide particles, thus representing an easy production And flexible solutions that can be used to overcome the above problems. Advantageously, the coatings of the present invention can be obtained in a single production step, for example by curtain coating.

本發明中的物件是高度透明的。本發明中的”高度透明”意謂所塗佈聚合物基材在可見光譜範圍內(550至750 nm)具有透射率至少達88%，較佳的是至少為90%以及最特別較佳的是在91至92%之間，其透射率測試方法是根據ASTM E 1348：“使用半球形幾何分光光度法測定透射率和顏色之標準試驗方法”，以及其未包含塗層之基材厚度為3 mm。 The articles of the present invention are highly transparent. "Highly transparent" in the context of the present invention means that the coated polymeric substrate has a transmission in the visible spectrum (550 to 750 nm) of at least 88%, preferably at least 90% and most preferably. It is between 91 and 92%, and its transmittance test method is based on ASTM E 1348: "Standard Test Method for Measuring Transmittance and Color Using Hemispherical Geometric Spectrophotometry", and the thickness of the substrate without the coating is 3 mm.

在本發明文中，”二氧化矽微粒”一詞係指基於二氧化矽(SiO₂)全部或部分交聯之結構，其平均粒子直徑(粒度)為2至15 μm，較佳的是3至10 μm，其是使用雷射光散射方法(動態光散射)測量。二氧化矽微粒可以是經表面處理(如以蠟處理)或不經修飾。較佳為未修飾(亦即未表面處理)之二氧化矽微粒。二氧化矽微粒是市售可取得的，如從INEOS Silicas Limited之Gasil HP 230， 其粒度為3.6 μm以及孔洞體積為1.6 ml/g。 In the context of the present invention, the term "cerium oxide particles" means a structure which is wholly or partially crosslinked based on cerium oxide (SiO ₂ ), and has an average particle diameter (particle size) of 2 to 15 μm, preferably 3 to 10 μm, which is measured using a laser light scattering method (dynamic light scattering).

The cerium oxide microparticles are commercially available, such as Gasil HP 230 from INEOS Silicas Limited, having a particle size of 3.6 μm and a pore volume of 1.6 ml/g.

含二氧化矽防刮塗層K是由耐刮或耐磨損之含有二氧化矽微粒的漆配方(如含二氧化矽之混成漆(hybrid lacquer)，像是矽氧烷漆(溶膠-凝膠漆))經由流塗、浸塗、噴塗、輥塗法或旋塗法而可得到。 The antimony-containing anti-scratch coating K is a scratch-resistant or wear-resistant paint formulation containing cerium oxide particles (such as a hybrid lacquer containing cerium oxide, such as a siloxane lacquer (sol-condensation) Glue)) can be obtained by flow coating, dip coating, spray coating, roll coating or spin coating.

本發明中混成漆之意義是基於使用混成聚合物當作黏結劑。混成聚合物(混成：lat.“屬於雙重來源”)是聚合物材料，其在單元結構裡由在分子層級上不同類別的材料組合而成。根據其結構，混成聚合物會具有完全新的性質組合。相較於複合材料(定義的相界限，在相與相之間僅有微弱的相互作用)以及奈米複合材(使用奈米尺寸填料)，混成聚合物的單元結構在分子層級上彼此交聯。這是藉由化學方法(像是例如溶膠-凝膠方法)而可形成其無機網絡。經使用有機反應性前驅物(像是有機修飾金屬烷氧化物)，可額外地製備得到有機寡聚物/聚合物結構。含有奈米粒子之經表面修飾丙烯酸漆，其在固化後形成有機/非有機網絡，也可定義為混成漆。存在有熱-固化以及UV-固化混成漆。 The meaning of the hybrid paint in the present invention is based on the use of a hybrid polymer as a binder. The hybrid polymer (mixed: lat. "belongs to a dual source") is a polymer material which is composed of materials of different classes at the molecular level in the unit structure. Depending on its structure, the hybrid polymer will have a completely new combination of properties. Compared to composites (defined phase boundaries, only weak interactions between phases) and nanocomposites (using nanoscale fillers), the unit structures of the hybrid polymers crosslink at the molecular level . This is by chemical means (such as, for example, a sol-gel process) to form an inorganic network. The organic oligomer/polymer structure can be additionally prepared by using an organic reactive precursor such as an organically modified metal alkoxide. A surface-modified acrylic lacquer containing nanoparticle, which forms an organic/non-organic network after curing, and can also be defined as a mixed lacquer. There are heat-curing and UV-curing hybrid paints.

Particularly preferred R may be C ₁ to C ₄ alkyl, methyl, ethyl, n-propyl, isopropyl, t-butyl, t-butyl or n-butyl or vinyl, allyl, A unit of a phenyl group or a substituted phenyl group. -OR's independently of one another, which is selected from the group consisting of a C ₁ to C ₆ alkyl group, the group consisting of hydroxy, methyl acyl group unit and acetyl units. In some cases, sol-gel polyoxyalkylene paints also fall within the definition of hybrid paints.

阻燃性可例如藉由下列一種或多種的阻燃測試而測得： Flame retardancy can be measured, for example, by one or more of the following flame retardant tests:

塑膠的阻燃性通常是使用UL94V(Underwriters Laboratories Inc.Standard of Safety)方法進行測試，"Test for Flammability of Plastic Materials for Parts in Devices and Appliances",pp.14 ff,Northbrook 1998；J.Troitzsch,"International Plastics Flammability Handbook",pp.346 ff.,Hanser Verlag,Munich 1990。在本測試中，以ASTM標準試樣評估續燃時間以及液滴行為。 The flame retardancy of plastics is usually tested using the UL94V (Underwriters Laboratories Inc. Standard of Safety) method, "Test for Flammability of Plastic Materials for Parts in Devices and Appliances", pp. 14 ff, Northbrook 1998; J. Troitzsch," International Plastics Flammability Handbook", pp. 346 ff., Hanser Verlag, Munich 1990. In this test, the afterburning time and droplet behavior were evaluated using ASTM standard samples.

關於防焰性塑膠之第一等級UL94V-0分類，必須符合下列條件：於一組5個ASTM標準試樣(尺寸：127 x 12.7 x X，其中X=試樣的厚度，像是3.2；3.0；1.51.0或0.75 mm)中，所有試樣在使用一定高度的明火下經兩次10秒期間的火焰燃燒後，繼續燃燒必須不能超過10秒鐘。 For the first grade UL94V-0 classification of flame-retardant plastics, the following conditions must be met: in a set of 5 ASTM standard specimens (size: 127 x 12.7 x X, where X = thickness of the specimen, such as 3.2; 3.0 In 1.51.0 or 0.75 mm), all samples shall not continue to burn for more than 10 seconds after being burned by flame for two 10 seconds under an open flame of a certain height.

5個試樣經過10次的火焰的續燃時間之總和必須不得多於50秒鐘。此外，各試樣在完全燒盡或餘燃(afterglow)於長於30秒也必須不能有燃燒液滴。UL94V-1等級須要個別試樣的續燃時間不得高於30 秒，以及5個試樣經過10次的火焰的續燃時間之總和必須不得多於250秒鐘。總餘燃時間必須不得超過250秒。其他參數與先前所提到是一致的。當符合UL94V-1等級之參數，但產生燃燒液滴時，將其分類為防焰UL94V-2等級。 The sum of the afterburning times of the flames of the five samples over 10 times must not exceed 50 seconds. In addition, each sample must not have combustion droplets after it has been completely burned out or afterglowed for longer than 30 seconds. UL94V-1 rating requires individual samples to have a renewed burn time of no more than 30 The sum of the seconds of the flame and the flames of the five samples over 10 times must not exceed 250 seconds. The total afterburning time must not exceed 250 seconds. Other parameters are consistent with those mentioned previously. When the parameters of UL94V-1 are met, but combustion droplets are produced, they are classified as flameproof UL94V-2.

此外，試樣的可燃性也可藉由測定限氧指數(根據ASTM 2863-77的LOI)進行評估。 In addition, the flammability of the sample can also be assessed by measuring the oxygen limited index (LOI according to ASTM 2863-77).

其他阻燃性測試包含根據DIN IEC 695-2-1之灼熱絲(glow wire)測試。在此，於連續三個試樣(例如60 x 60 x 2 mm或1 mm的膜片上)藉助溫度在550至960℃之間的灼熱絲，量測其最高溫度，其中不超過30秒鐘的續燃時間以及樣品未發出燃燒顆粒。此測試特別是使用在電氣/電子產業裡、因在缺陷或超載的物件中，在電子產品中的元件可以承受如此高溫而讓鄰近的部分立即被點燃。在此灼熱絲測試中，可重新創建這種類型的熱應力。 Other flame retardancy tests include a glow wire test in accordance with DIN IEC 695-2-1. Here, the maximum temperature is measured in three consecutive samples (for example on a 60 x 60 x 2 mm or 1 mm diaphragm) by means of a glow wire with a temperature between 550 and 960 °C, of which no more than 30 seconds The afterburning time and the sample did not emit combustion particles. This test is particularly useful in electrical/electronic industries where components in an electronic product can withstand such high temperatures and cause adjacent portions to be immediately ignited due to defects or overloaded items. This type of thermal stress can be recreated in this glow wire test.

灼熱絲測試中有一種特別型式，根據IEC 60695-1-13的灼熱絲點燃測試，主要是著重在試樣之點燃行為。在此，在測試期間樣品不能被點燃，點燃的定義為外觀上有長達5秒鐘以上的火焰。不允許樣品有燃燒液滴的情形產生。 There is a special type in the glow wire test, which is based on the glow wire ignition test of IEC 60695-1-13, focusing primarily on the ignition behavior of the sample. Here, the sample cannot be ignited during the test, and the ignition is defined as a flame having an appearance of more than 5 seconds. It is not allowed to have a sample with burning droplets.

根據本發明的物件通過一種或多種上述提及之阻燃測試，並且具有其他優越的性質，特別是關於耐刮以及耐磨損性、透射率/透明度以及彩虹效應。 Articles according to the present invention pass one or more of the flame retardant tests mentioned above and have other superior properties, particularly with regard to scratch and abrasion resistance, transmission/transparency, and rainbow effects.

經塗佈的物件是高度透明的。特別地，在3 mm層厚以及波長為550 nm下，其透射率至少為88%，較佳的是高於89%以及特別最佳的是高於89.5%或高於90%，或者在波長為700 nm下，其透射率至少為90%，較佳的是高於91%以及特別最佳的是高於91.5%或高於92%。 The coated article is highly transparent. In particular, at a layer thickness of 3 mm and a wavelength of 550 nm, the transmittance is at least 88%, preferably above 89% and particularly preferably above 89.5% or above 90%, or at wavelength At 700 nm, the transmission is at least 90%, preferably above 91% and particularly preferably above 91.5% or above 92%.
