|
更新日期： 2020-5-22 |
回顧上一期內(nèi)容，我們對脂環(huán)族環(huán)氧樹脂做了較為簡單的概述，但沒有針對它的不同類型及其應(yīng)用進(jìn)行對比介紹。作為中國最大的脂環(huán)族環(huán)氧樹脂生產(chǎn)廠家，新納希將在本期內(nèi)容里重點(diǎn)介紹各類脂環(huán)族環(huán)氧樹脂及其在光固化領(lǐng)域的應(yīng)用，歡迎大家集思廣益，給予我們更多的建議。
Let's review the previous article, in which we gave a simple overview of the cycloaliphatic epoxy resin, but we did not provide a comparative introduction to its different types and applications. As China's largest cycloaliphatic epoxy resin manufacturer, Synasia will give you an introduction of different cycloaliphatic epoxy resins and their UV curing applications in this article. Welcome all of you to brainstorm and give us more advice.
先用一張圖來帶您了解我們主打的幾款脂環(huán)族環(huán)氧樹脂。
Let's start with a table list to show you some of our typical cycloaliphatic epoxy resins.
01 S-06E
作為一款高純度、低粘度、低鹵素的脂環(huán)族環(huán)氧樹脂，S-06E透明度高，總氯含量(VOC) 可做到50ppm以內(nèi)，具有出色的抗紫外線性能和抗輻射性能。它既可光固化，也可與酸酐 (甲基四氫苯酐，甲基六氫苯酐) 進(jìn)行熱固化，在催化劑作用下可與脂肪胺固化，常用于光固化涂料、電子膠、絕緣材料、LED封裝膠、3D打印等行業(yè)，尤其用于LED封裝等電子行業(yè)時，能發(fā)揮極好的電絕緣性能。
As a high-purity, low-viscosity, low-halogen cycloaliphatic epoxy resin, S-06E is highly transparent and its total chlorine content (VOC) can be controlled within 50ppm. Besides, it has excellent UV resistance and anti-radiation properties. This product is UV curable or thermal curable with anhydride (methyl tetrahydrobenzene, methyl hexahydrogenbenzene). It can be cured with aliphatic amine in the presence of a catalyst. S-06E is often used in UV coatings, electronic adhesives, insulation materials, LED encapsulants, 3D printing and other industries. Especially when used in electronic industries, e.g., LED encapsulation, it plays an outstanding electrical insulation performance.
02 S-21
S-21與S-06E的CAS號相同，屬于同一物質(zhì)，只是S-21純度略低，價格也略低，常用于光固化涂料、光固化油墨、復(fù)合材料、UV膠等行業(yè)，對鹵素要求并不嚴(yán)格。
S-21 and S-06E share the same CAS number, but S-21 is cheaper and its purity is slightly lower. This product is often used in industries like UV inks, UV coatings, UV adhesives, composites, etc., where the halogen content is not highly demanded.
S-28是一款柔韌性極佳的脂環(huán)族環(huán)氧樹脂，適用于需要更高粘度或更柔韌薄膜的眾多應(yīng)用中。它既可以進(jìn)行光固化，也可以和酸酐進(jìn)行熱固化。典型應(yīng)用包括金屬裝飾涂料、罩光油、軟包裝和層壓粘合劑。
S-28 is a highly flexible cycloaliphatic epoxy resin, which is suitable for many applications that require higher viscosity or more flexible films. It can be UV cured or thermally cured with anhydride. Typical applications include metal decorative coatings, overprint varnish, flexible packaging and laminating adhesives.
04 S-28E
同樣地，S-28E與S-28的CAS號相同，屬于同一物質(zhì)，由于我們對S-28E進(jìn)行了嚴(yán)格的鹵素控制，總氯含量可以達(dá)到50ppm以內(nèi)，主要應(yīng)用于LED封裝、光固化油墨和涂料、高壓電器元件、電容油、變壓器油等領(lǐng)域。
Likewise, S-28E and S-28 share the same CAS number. Because we have strictly controlled the halogen content of S-28E, the total chlorine content can reach less than 50ppm. Main applications include LED encapsulant, UV curing ink/coating, high-voltage electrical component, capacitor oil, transformer oil and other fields.
02 UV陽離子固化原理 Cationic UV-Curing Principle
UV(紫外)光固化材料在紫外光的照射下，具有化學(xué)活性的液體配方在基體表面實(shí)現(xiàn)快速固化形成的固態(tài)涂膜。作為一種新型技術(shù)，UV固化技術(shù)具有“5E”的特點(diǎn)：Efficiency (高效)，UV固化設(shè)備緊湊，可連續(xù)生產(chǎn)，提高效率；Economy (經(jīng)濟(jì))，UV固化工藝節(jié)省原料，能有效降低成本；Energy (節(jié)能)，固化時間短，無需加熱，可節(jié)約能源；Ecology (生態(tài))，體系VOC含量低，生產(chǎn)中無過多有害氣體；Enabling (多能)，可適用于木材、金屬、塑料等多種基材的表面施工過程。
UV (Ultraviolet) curing material is formed under ultraviolet light, where a chemically active liquid formulation can be rapidly changed into a solid coating film on substrate surface. This innovative UV-curing technology has the characteristics of "5E": Efficiency, because UV curing equipment is compactly structured and it can realize continuous production for increased efficiency; Economy, because UV curing process can save raw materials and it can effectively reduce costs; Energy, because short curing time and no heating can save energy; Ecology, due to low VOC content and no excessive harmful gas in production; Enabling, because it is suitable for processing on surface of many kinds of substrate such as wood, metal, plastic, etc.
環(huán)氧樹脂在涂料中的應(yīng)用占較大比例，它能制成各具特色、用途各異的品種。其共性：
Epoxy resins are most widely used in coatings of different characteristics and applications. Their common features include:
(1)耐化學(xué)品性優(yōu)良，尤其是耐堿性。
Excellent chemical resistance, especially for alkali and acid.
(2)漆膜附著力強(qiáng)，特別是對金屬。
Strong adhesion to paint film, especially for metal.
(3)具有較好的耐熱性和電絕緣性。
Good heat resistance and electrical insulation.
(4)漆膜保色性較好。
Protect the color of paint film well.
雙酚A型環(huán)氧樹脂涂料的耐候性較差，漆膜在戶外易粉化失光又欠豐滿，不宜用作戶外涂料及高裝飾性涂料。因此普通環(huán)氧樹脂涂料主要用作防腐蝕漆、金屬底漆、絕緣漆，但雜環(huán)及脂環(huán)族環(huán)氧樹脂制成的涂料可以用于戶外。
Bisphenol A type epoxy resin coatings feature poor weatherability. Their paint film is easily powdered and lack of fullness, which makes them not suitable for use in outdoor coatings or highly decorative coatings. Thus ordinary epoxy resin coatings are mainly used for anti-corrosion paint, metal primer and insulating paint. However the coatings which are made of heterocyclic or cycloaliphatic epoxy resins can be used outdoors.
紫外光固化涂料因其固化快、無需高溫、不產(chǎn)生氣泡、膜面光澤好等優(yōu)點(diǎn)日益受到廣泛重視。以脂環(huán)族環(huán)氧為主要成分制得的這類涂料耐候性強(qiáng)、硬度高、耐磨、抗沖擊、耐化學(xué)腐蝕、粘接性好，可用于印刷線路板阻焊油墨、光盤的外涂料及金屬、塑料的罩面保護(hù)等。
Ultraviolet (UV) curing coatings become increasingly emphasized due to their advantages of fast cure, good film gloss, no bubble, no need for high temperature, etc. The coating which uses cycloaliphatic epoxy resin as main ingredient provides strong weatherability, high hardness, good adhesion, as well as good resistance to abrasion, impact and chemical corrosion. It can be used for PCB inks, optical disc coatings, as well as metal or plastic cover protection, etc
UV-Curing 3D Print Application
由于脂環(huán)族環(huán)氧樹脂具有低粘度、低溶脹、固化快、低收縮率、高光敏度的特點(diǎn)，在光固化領(lǐng)域有著極為廣闊的應(yīng)用前景，尤其在新興市場——3D打印領(lǐng)域，下游客戶對高性能配方的追求以及政府對環(huán)保要求的提高，必定會推動脂環(huán)族環(huán)氧樹脂需求的大幅增長。
Due to its characteristics of low viscosity, low swelling ratio, low shrinkage rate, fast cure and high photosensitivity, cycloaliphatic epoxy resin has an extremely board application prospect in UV curing field. Especially in 3D printing emerging market, where customers seek for high-performance formulation and the government has raised demand for environmental protection, it will undoubtedly drive a significant increase in demand for cycloaliphatic epoxy resins.
脂環(huán)族環(huán)氧樹脂通常用于SLA光固化立體成型的陽離子感光體系，應(yīng)用領(lǐng)域包括：
Cycloaliphatic epoxy resin is usually applied in SLA (Stereo Lithography Appearance) cationic photosensitive system. Typical applications include:
(1)電子產(chǎn)品模具開發(fā)
Electronic product mold development
(2)用于工程設(shè)計(jì)的測試模型制作
Test model for engineering design
(3)三維人體及器官復(fù)制，用于輔助診斷、輔助手術(shù)等
3D human body and organ replication for auxiliary diagnosis, assisted surgery, etc.
