Embodiment 1

[0027] The amino-terminated polyurethane prepolymer solution containing urea groups in component A is polymerized by solution polymerization of polyetheramine, polyether diol, diisocyanate, and amine chain extender. The specific preparation method is as follows:

[0028] Put 60 parts of polyether glycol DL1000 (commercially available) into the reaction kettle at room temperature, vacuum dehydration at 90-100℃ for 1-2 hours, take a sample to determine the moisture content, when the moisture content is less than 0.08%, stop dehydration and cool to 40-45℃ and maintain this temperature range, turn on the stirring, add 10 parts of ethyl acetate and 30 parts of liquefied MDI (diphenylmethane diisocyanate) in turn while stirring. After the temperature stabilizes, slowly increase the temperature to 70 Reaction at ℃, after 2 hours, measure the NCO value (4%-6%), and lower the temperature to about 42℃, put in 25 parts of polyetheramine D230 (commercially available), 5 parts of diethylene t...

Abstract

The invention relates to a bi-component high-temperature resistant alcohol-soluble ink binder, as well as a preparation method and the application of the bi-component high-temperature resistant alcohol-soluble ink binder, belonging to the technical field of ink binders. The bi-component high-temperature resistant alcohol-soluble ink binder comprises a component A and a component B which are separately stored, wherein the component A contains amino-terminated polyurethane prepolymer solution; and the component B is epoxy resin alcohol solution modified by amino silane coupling agent. The preparation method of the alcohol-soluble ink binder comprises the following steps of: carrying out vacuum dehydration on polyether diol until the water content is less than 0.08%; cooling to 40-45 DEG C; sequentially adding ethyl acetate and diisocyanate while stirring; after the temperature is stable, heating up to 70 DEG C until the measured NCO value is 4-6%; cooling and adding polyether amine, diethylenetriamine, acetone, isopropyl alcohol and alcohol; heating up to 70-75 DEG C; and maintaining even backflow until ketone is completely removed, and taking the product as the component A. The bi-component high-temperature resistant alcohol-soluble ink binder can be applied to ink printing, is wide in printing application scope and good in ink attachment fastness, and can resist high temperature.

Description

Technical field [0001] The invention belongs to the technical field of ink binders, and specifically relates to a two-component high-temperature resistant alcohol-soluble ink binder, preparation method and application. Background technique [0002] In recent years, governments of various countries have paid more and more attention to the standardized management of various food packaging materials. In addition, the domestic demand for food health and safe consumption is also increasing. In particular, my country’s food packaging industry has fully implemented QS certification and ink industry environmental certification. The application of ink for flexible packaging has required a full conversion to environmental protection, safety and health standards. . To maintain sustainable development, packaging companies must face packaging safety issues and actively improve the environmental safety standard system. Many companies have developed and produced benzene-free and ketone-free so...
