一种甜味上光油及其制备方法
摘要：
一种甜味上光油及其制备方法，涉及印刷品技术领域。一种甜味上光油，按照重量份数计，包括：甜味剂10‑15份，溶剂52‑62份，树脂18‑33份，流平剂3‑6份，溶剂包括去离子水、体积分数为90‑96％的乙醇、乙酸乙酯、二丙二醇甲醚和γ‑丁内酯。该甜味上光油具有甜味纯正、储存稳定性强、适用于200‑300m/min的高速印刷机等优点。该制备方法为：将甜味剂与去离子水混合制得甜味剂分散液；将乙醇与甜味剂分散液混合制得甜味剂溶液；将乙酸乙酯、乙醇、二丙二醇甲醚、γ‑丁内酯、流平剂与树脂混合制得树脂液，将甜味剂溶液与树脂液混合。该制备方法简单，适用于工业化大规模生产。
摘要（英）：

The invention relates to the technical field of printed products, in particular to a sweet varnish and a preparation method thereof. The sweet varnish comprises, by weight, 10-15 parts of a sweetener, 52-62 parts of a solvent, 18-33 parts of resin, and 3-6 parts of a leveling agent; the solvent comprises deionized water, ethanol having volume fraction of 90-96%, ethyl acetate, dipropylene glycol monomethyl ether, and Upsilon-butyrolactone. The sweet varnish has the advantages of pure sweetness, high storage stability, applicability to high-speed printers 200-300 m/min. The preparation method comprises: mixing a sweetener and deionized water to obtain sweetener dispersion; mixing ethanol and the sweetener dispersion to obtain sweetener solution; mixing ethyl acetate, ethanol, dipropylene glycol monomethyl ether, Upsilon-butyrolactone, a leveling agent and resin to obtain resin liquid, and mixing the sweetener solution with the resin liquid. The preparation method is simple and is applicable to industrial large-scale production.
