脂环族环氧树脂:光固化应用篇

更新日期: 2020-5-22  

回顾上一期内容,我们对脂环族环氧树脂做了较为简单的概述,但没有针对它的不同类型及其应用进行对比介绍。作为中国最大的脂环族环氧树脂生产厂家,新纳希将在本期内容里重点介绍各类脂环族环氧树脂及其在光固化领域的应用,欢迎大家集思广益,给予我们更多的建议。 

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. 



01

先用一张图来带您了解我们主打的几款脂环族环氧树脂。

Let's start with a table list to show you some of our typical cycloaliphatic epoxy resins. 




对比分析 ‖ COMPARATIVE ANALYSIS

01 S-06E

作为一款高纯度、低粘度、低卤素的脂环族环氧树脂,S-06E透明度高,总氯含量(VOC) 可做到50ppm以内,具有出色的抗紫外线性能和抗辐射性能。它既可光固化,也可与酸酐 (甲基四氢苯酐,甲基六氢苯酐) 进行热固化,在催化剂作用下可与脂肪胺固化,常用于光固化涂料、电子胶、绝缘材料、LED封装胶、3D打印等行业,尤其用于LED封装等电子行业时,能发挥极好的电绝缘性能。

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与S-06E的CAS号相同,属于同一物质,只是S-21纯度略低,价格也略低,常用于光固化涂料、光固化油墨、复合材料、UV胶等行业,对卤素要求并不严格。

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.


03 S-28

S-28是一款柔韧性极佳的脂环族环氧树脂,适用于需要更高粘度或更柔韧薄膜的众多应用中。它既可以进行光固化,也可以和酸酐进行热固化。典型应用包括金属装饰涂料、罩光油、软包装和层压粘合剂。

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

同样地,S-28E与S-28的CAS号相同,属于同一物质,由于我们对S-28E进行了严格的卤素控制,总氯含量可以达到50ppm以内,主要应用于LED封装、光固化油墨和涂料、高压电器元件、电容油、变压器油等领域。

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阳离子固化原理 
Cationic UV-Curing Principle



UV(紫外)光固化材料在紫外光的照射下,具有化学活性的液体配方在基体表面实现快速固化形成的固态涂膜。作为一种新型技术,UV固化技术具有“5E”的特点:Efficiency (高效),UV固化设备紧凑,可连续生产,提高效率;Economy (经济),UV固化工艺节省原料,能有效降低成本;Energy (节能),固化时间短,无需加热,可节约能源;Ecology (生态),体系VOC含量低,生产中无过多有害气体;Enabling (多能),可适用于木材、金属、塑料等多种基材的表面施工过程。

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.



光固化涂料/油墨应用
UV Coating / Ink Application

环氧树脂在涂料中的应用占较大比例,它能制成各具特色、用途各异的品种。其共性:

Epoxy resins are most widely used in coatings of different characteristics and applications. Their common features include:

(1)耐化学品性优良,尤其是耐碱性。

Excellent chemical resistance, especially for alkali and acid.  

(2)漆膜附着力强,特别是对金属。

Strong adhesion to paint film, especially for metal. 

(3)具有较好的耐热性和电绝缘性。

Good heat resistance and electrical insulation. 

(4)漆膜保色性较好。

Protect the color of paint film well. 

双酚A型环氧树脂涂料的耐候性较差,漆膜在户外易粉化失光又欠丰满,不宜用作户外涂料及高装饰性涂料。因此普通环氧树脂涂料主要用作防腐蚀漆、金属底漆、绝缘漆,但杂环及脂环族环氧树脂制成的涂料可以用于户外。

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、无需高温、不产生气泡、膜面光泽好等优点日益受到广泛重视。以脂环族环氧为主要成分制得的这类涂料耐候性强、硬度高、耐磨、抗冲击、耐化学腐蚀、粘接性好,可用于印刷线路板阻焊油墨、光盘的外涂料及金属、塑料的罩面保护等。

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


光固化3D打印应用UV-Curing 3D Print Application

由于脂环族环氧树脂具有低粘度、低溶胀、固化快、低收缩率、高光敏度的特点,在光固化领域有着极为广阔的应用前景,尤其在新兴市场——3D打印领域,下游客户对高性能配方的追求以及政府对环保要求的提高,必定会推动脂环族环氧树脂需求的大幅增长。

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. 


脂环族环氧树脂通常用于SLA光固化立体成型的阳离子感光体系,应用领域包括:

Cycloaliphatic epoxy resin is usually applied in SLA (Stereo Lithography Appearance) cationic photosensitive system. Typical applications include:  

(1)电子产品模具开发

Electronic product mold development

(2)用于工程设计的测试模型制作

Test model for engineering design

(3)三维人体及器官复制,用于辅助诊断、辅助手术等

3D human body and organ replication for auxiliary diagnosis, assisted surgery, etc.
