Abstract

The invention discloses high-solid UV (ultraviolet) curing ink which is characterized by being made from raw materials in parts by weight as follows: 1-3 parts of organic pigments, 20-24 parts of urethane acrylate, 1-2 parts of nano carbon black pigments, 4-5 parts of ferrous sulfate, 2-3 parts of titanium dioxide, 35-40 parts of urethane acrylate, 14-18 parts of dipropylene glycol diacrylate, 1-2 parts of molybdenum oxide, 30-35 parts of epoxy acrylate, 4-8 parts of 2959 photoinitiators, 3-5 parts of 184 photoinitiators, 1-2 parts of 2-n-Octyl-4-isothiazolin-3-ketone, 2-3 parts of polyacrylamide and 4-5 parts of aids. According to the high-solid UV curing ink and a preparation method thereof, the toughness of the ink is improved, the ink can be uniformly dispersed, and the ink stability is maintained; and the high-solid UV curing ink is dry, short in curing time, simple in construction process, high in production efficiency, environment-friendly and nontoxic.

Description

A kind of high solid UV curing inks and preparation method thereof

Technical field

The present invention relates to a kind of ink and preparation method thereof, particularly a kind of high solid UV curing inks and preparation method thereof.

Background technology

The curing mechanism of UV curable ink is, the light trigger in system directly or indirectly absorbs after ultraviolet luminous energy, from ground state transition to excited singlet, alters and jump to excited triplet state between being; After excited singlet or triplet state experience unit molecule or bimolecular chemical action, the biologically active fragment that generation can trigger monomer polymerization, these fragments can be free radical, positively charged ion, negatively charged ion or ion free radical.

There has been significant progress nearest for some time of UV curable ink, and its major advantage is: set time is short, therefore needn't use and dust, and can enhance productivity; Owing to just need not heating, can be dried, so do not need baking oven, compare with thermal fixation type ink, can significantly reduce time of drying, save energy consumption; The various resistances of printing are good, and dry rear ink film is solid; Due to the good stability of ink on machine, so the stable in properties of printed matter; Non-volatility organic solvent VOC in ink, can atmosphere pollution, and printed matter is odorless almost; Because be the ink of solids content 100%, so can carry out thick film screen printing; Can on cheap paper, print, also can non-absorbent material as metallic substance, plastics, silicate product etc. on printing.Like this, from the viewpoint of high speed printing, environment protection and save energy etc., UV curable ink is all better than other types ink.

Summary of the invention

The object of this invention is to provide a kind of high solid UV curing inks and preparation method thereof.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A high solid UV curing inks, is made by the raw material of following weight part: pigment dyestuff 1-3, urethane acrylate 20-24, nano carbon black pigment 1-2, ferrous sulfate 4-5, titanium dioxide 2-3, urethane acrylate 35-40, propylene glycol diacrylate 14-18, molybdenum oxide 1-2, epoxy acrylate 30-35,2959 light trigger 4-8,184 light trigger 3-5, di-n-octyl-4-isothiazoline-3-ketone 1-2, polyacrylamide 2-3, auxiliary agent 4-5;

Described auxiliary agent is prepared from by the raw material of following weight part: nano diatomite powder 0.2-0.3, nano mica powder 0.2-0.3, Silane coupling agent KH550 1-2, linking agent TAC2-3, polyisobutene 2-3, sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester 2-3, phenylformic acid amine 1-2, Viscoat 295 10-12, Tenox PG 2-3, coix seed oil 1-2; Its preparation method is by each mixing of materials, is heated to 60-70 ℃, and stirring reaction 30-40 minute, obtains.

The solid UV curing inks of height of the present invention, by following concrete steps, made: first add pigment dyestuff, urethane acrylate, nano carbon black pigment, ferrous sulfate, titanium dioxide, urethane acrylate, propylene glycol diacrylate stirring and evenly mixing, be heated to 80-90 ℃, stir 25-35 minute; Then add all the other remaining components except 2959 light triggers, 184 light triggers, stirring reaction 3-5 hour; Finally be cooled to 60-70 ℃, add 2959 light triggers, 184 light triggers, stirring reaction 40-50 minute, cooling after, grind and to obtain 20-40 μ m slurry, obtain.

The invention has the beneficial effects as follows: auxiliary agent of the present invention has improved the toughness of ink, make distributes ink even, and maintained the stability of ink; The present invention is dry, set time is short, and construction technology is simple, and production efficiency is high, environment-protecting asepsis.
