Abstract

The invention discloses a preparation method for wear-resisting plant oil-based ink. According to the preparation method for the wear-resisting plant oil-based ink, water, vegetable oil, cholamine, an organic silicon defoamer and a soya bean lecithin wetting agent which are taken in a certain proportion and sequentially mixed into a dispersion pot, the components are dispersed uniformly, filtration is conducted after the dispersing, filtered emulsion is taken, and then the collected emulsion, water-soluble acrylic resin, water-based crylic acid color paste and polypropylene wax micro powder are sequentially mixed into the dispersion pot, the components are uniformly dispersed, an appropriate amount of the organic silicon defoamer is added, and finally the product is obtained through filtration.

Description

A kind of preparation method of wear-resisting plant oil-based ink

Technical field

The present invention relates to a kind of ink, particularly a kind ofly add micro-plant oil-based ink of wax and preparation method thereof, belong to ink chemical field.

Summary of the invention

Along with the fast development of packaging and publication and printing industry both at home and abroad, ink application is also increasingly extensive, ink industry is produced and is also day by day accelerated, ink industry is by introducing and digesting advanced foreign technology, China's Printing ink producing and equipment have had and have significantly improved, and output constantly increases, and China's ink industry in 2010 is produced and reached all-time high, whole nation ink gross annual output amount amounts to 58.99 ten thousand tons, accounts for 14% of the whole world.

Ink is a kind of to be mixed equably by pigment, low-melting ink vehicle and auxiliary agent etc. and through the gluey fluid of a kind of viscosity of repeat-rolling.In China, what ink production was produced substantially is traditional synthetic resins ink, mostly all organic (or inorganic) solvent will be contained in this kind of ink, thus containing more multiring aromatic hydrocarbon substance, and 3,4-benzo pyrroles, 3-nitro benzo ketone etc. are wherein also containing carcinogenic components, on printed matter, residual quantity is large, the survival time is long, can endanger user's health, is also the important source of pollution in Printing ink producing process simultaneously.Nowadays; along with the raising of people's environmental consciousness and growing to even greater heights of environment protection cry; ink is as the chief component of green printing; its environmental requirement is also strengthened day by day; have the regulation limitations such as heavy metal content, packing material solvent residues amount and other VOC limit standard in other related fields such as food product pack especially, exploitation non-toxic ink is the study hotspot of current ink.Make solvent with vegetables oil, the ink of preparation not only environmental protection but also the resource of available regenerative replaces non-renewable petroleum solvent, and is easier to deinking to useless printed matter process than traditional ink when reclaiming.But the rate of drying of plant oil-based ink is slow, limits the use range of plant oil-based ink.

Ultra-fine micropowder technology is the new and high technology grown up in recent years, and generally the particle that particle diameter is less than 0.5 μm is called ultramicron, the particle of less than 20 μm is called micropartical, and the aggregate of ultrafine particle is called ultrafine powder.Micronization wax is widely used in printing-ink with the performance of its excellence, improves its wear resisting property.The present invention is in ink-making process, adds Poly Propylene Wax micro mist, prepares the plant oil-based ink that a kind of wear resistance is strong.

Summary of the invention

The invention provides a kind of preparation method of wear-resisting plant oil-based ink, the method is carried out as follows:

(1) get the water of 20%, 25% vegetables oil, the thanomin of 15%, the silicone antifoam agent of 0.5% and 1% soybean lecithin wetting agent put in a dispersion cylinder container successively;

(2) press the rotating speed of 500-600 r/min, dispersed 2-3 hour;

(3) after dispersion, by the liquid filtering of dispersion;

(4) collect the emulsion of filtration, then pour in dispersion cylinder, add the water soluble acrylic resin of 25%, the water soluble acrylic acid mill base of 10% and the Poly Propylene Wax micro mist of 3% successively, by the rotating speed of 600-800r/min, dispersed 2-4 hour;

(5) filter after finally adding the silicone antifoam agent of 0.5%, the strong plant oil-based ink of a kind of wear resistance.

The present invention has following advantages and characteristic:

(1) preparation technology is simple, easily operates;

(2) raw material sources are extensive, with low cost.
