Abstract

The invention relates to a polyurethane pure water ink linking material and pure water ink. The pure water ink system is prepared by dispersing and grinding a pure water ink linking material added with pure water, an organic pigment, a dispersant, aqueous wax powder, a defoamer and a thickener. For producing low-cost pure water ink with high performance, a polyether glycol and a polyester glycol, which are polymer materials, are mixed and dehydrated, the product of the dehydration is added with isocyanate, dimethylolpropionic acid, trimethylolethane and hydroxy-ethyl acrylate to undergo reactions under conditions of vacuum and temperature control for several hours, the reaction solution is neutralized, and the pure water is added into the reaction solution to form compound emulsion, and a further reaction is performed to form the pure water ink linking material. The pure water is used in place of harmful solvents such as methylbenzene and butanone. The pure water ink can be printed on paper boxes, paper and PET and PE plastic thin films. The ink is non-combustible, nontoxic, harmless, environmentally-friendly, safe, energy-saving and low in cost.

Description

Urethane pure water ink linking material and pure water ink thereof

Technical field:

The present invention relates to a kind of printing ink, be specifically related to the production technique and the prescription of a kind of urethane pure water ink linking material and pure water ink thereof.

Background technology:

At present, though China has banned hypertoxic toluene solvent type printing ink, also be to use solvent type ink more than 95%.Inflammable and explosive, contaminate environment, the contaminated food products packing, poisonous and harmful, harm workshop workman's is healthy.Along with the appearance of environment-friendly type aqueous printing ink, " green food and Green Packaging ",, paid close attention to by people day by day because pure water ink is not fired, nontoxic, harmless, environmental protection, safety, health, save energy, with low cost.Pure water ink can be printed on carton, paper aspects such as food product pack, tobacco and wine packing, toy for children packing, can also be printed on the plastics film with PET, PE master.

Summary of the invention:

The pure water ink that the present invention relates to is to make solvent with pure water, replaces toluene butanone equal solvent, does not fire, nontoxic, harmless, environmental protection, safety, health, save energy, with low cost; Paid close attention to by people day by day; Can not only print the packing of food, medicine, tobacco and wine, beverage and paper aspect, can also be printed on PET, PE is in master's the plastic wrapping, and purposes is very extensive; With low cost, be easy to scale operation.

To achieve these goals, urethane pure water ink linking material of the present invention and pure water ink thereof are that polyvalent alcohol and polyester are that polyvalent alcohol, isocyanic ester, dimethylol propionic acid, trimethylolethane, Hydroxyethyl acrylate, quadrol, emulsifying agent, pure water, pure water ink linking material, pigment dyestuff, auxiliary agent are formed by polyethers.

The weight percent of contained each component is:

Polyethers is polyvalent alcohol 5-15%; Linking material 30-60%;

Polyester is polyvalent alcohol 5-15%; Pure water 20-50%;

Isocyanic ester 5-20%; Pigment dyestuff 8-15%;

Quadrol 0.5-1.5% auxiliary agent 2-15%;

Emulsifying agent 1-7%

Dimethylol propionic acid 1-10%;

Trimethylolethane 1-10%;

Hydroxyethyl acrylate 1-20%;

Pure water 22-60%.

The production technique of urethane pure water ink linking material and pure water ink thereof.Step is following:

Neutralize with quadrol and emulsifying agent after 12 hours in the 85 degree reactions of temperature control under the condition of negative pressure with adding isocyanic ester and dimethylol propionic acid, trimethylolethane behind polyether glycol and the polyester polyol mixed dehydration earlier; Add pure water again and generate composite emulsion, continue reaction and generated the pure water ink linking material in 1 hour.Add pure water, pigment dyestuff and auxiliary agent in proportion again with linking material and after dispersion grinding, become pure water ink.

The pure water ink rate of drying that the present invention makes is fast, and printing adaptability is better, and transitivity is good, and attachment fastness is good, is particularly suitable for plastic film packagings such as tobacco and wine packing, PET, PE, because use pure water mostly, cost is just very low.
