Update： 2021-3-29 |
UV光固化技術(shù)是一種高效、環(huán)保、節(jié)能、優(yōu)質(zhì)的面向21世紀的新技術(shù)，廣泛應(yīng)用于涂料、膠黏劑、油墨、光電子等領(lǐng)域。
UV curing technology is a high-efficiency, environmentally friendly, energy-saving, advanced technology in the 21st century, which is widely used in coatings, adhesives, inks, optoelectronics and other fields.
自1946年美國Inmont公司取得第一個UV光固化油墨專利、1968年德國Bayer公司開發(fā)了第一代UV光固化木器涂料以來，光固化涂料在全球獲得迅速發(fā)展。近幾十年來，一大批新型、高效的光引發(fā)劑、樹脂、單體和先進的UV光源被應(yīng)用于UV光固化行業(yè)，促進了行業(yè)的發(fā)展。
Since the American Inmont company obtained the first UV curable ink patent in 1946, and the German Bayer Company developed the first generation of UV curable wood coatings in 1968, UV curable coatings have developed rapidly all over the world. In recent decades, a large number of new and efficient photoinitiators, resins, monomers and advanced UV light sources have been applied to the UV curing industry, which has promoted industry development.
脂環(huán)族環(huán)氧樹脂是含有兩個脂環(huán)環(huán)氧基的低分子化合物。其本身不是聚合物，但是與固化劑作用后能生成性能優(yōu)異的三維體型結(jié)構(gòu)的聚合物。具有低粘度、熱穩(wěn)定性好、低鹵素含量和優(yōu)良電氣性能、耐紫外線耐黃變優(yōu)異、UV固化無氧阻聚、低遷移性等優(yōu)勢。
The cycloaliphatic epoxy resin is a low molecular compound containing two cycloaliphatic epoxy groups. It is not a polymer itself, but when reacting with the curing agent it can generate a polymer with excellent-performance three-dimensional structure. Advantages include low viscosity, good thermal stability, low halogen content, great electrical performance, excellent UV-resistant and non-yellowing performance, low migration and no oxygen inhibition after UV curing, etc.
