Abstract

The invention discloses printing ink and a preparation method thereof, wherein the printing ink is mainly prepared from the following raw materials in parts by weight: 40-60 parts of acrylic resin, 20-45 parts of amino resin, 2-8 parts of ethanol, 1-10 parts of isophorone, 1-10 parts of DPM solvent, 6-12 parts of DBE solvent, 3-8 parts of toner, 1-4 parts of fumed silica, 0.1-2 parts of defoaming agent, 1-8 parts of dispersing agent and 1-3 parts of silane adhesion promoter. The components are added in sequence according to parts, stirred at a constant speed for enough time, ground by using a three-roller machine, and filtered to obtain the product. The invention aims to provide printing ink with excellent chemical resistance, so as to meet the requirement of people on the durability of toughened glass surface decoration used in household appliances, touch panels, home decoration and the like, and ensure that the surface decoration ink of the product cannot fall off for a long time.

Description

A kind of printing-ink

Technical field

The present invention relates to a kind of printing-ink, specifically refer to a kind of printing-ink that is applied in the toughened glass surface, the invention also discloses the preparation method of this printing-ink.

Technical background

Now all can use toughened glass as goods such as the places such as house ornamentation (bathroom), household electrical appliances (refrigerator, air-conditioning), contact panels (mobile phone, panel computer, navigating instrument).With the toughened glass that the traditional glass printing-ink is processed, 50 meetings of ethanol-tolerant wiping are faded, and anti-butanone wiping has for 10 times the situation of fading to occur, and water boiling resistance can be bubbled, be come off in 30 minutes.The toughened glass that use is processed through traditional printing printing ink can cause above-mentioned field of employment or product surface to be easy to occur the phenomenons such as printing ink comes off, scratches.

Summary of the invention

The printing-ink that the purpose of this invention is to provide a kind of endurance excellence, to solve existing printing-ink in anti-scratch, wear-resisting, water-fast, the deficiency of the aspect such as chemicals-resistant especially, thereby the said products can not come off at the decorative ink of longer for some time internal surface in the requirement that the weather resistance that satisfies the toughened glass surface decoration that people use household electrical appliances, contact panel, house ornamentation etc. improves.

For addressing the above problem, solution of the present invention is:

A kind of printing-ink, mainly made by the raw material of following parts by weight:

Wherein, solvent is that effective constituent is 99.1% DBE, isophorone, DPM.

Defoamer preferably contains silicon defoaming agent, can help froth breaking and printing from the net effect, makes printing effect more attractive in appearance.

Acrylic resin plays 80% effect for water-repellancy and anti-butanone, should select solid content at 50% resin to guarantee the sticking power of printing ink, the too high printing ink that easily causes of hydroxyl value is too soft, that admittedly contain and the hydroxyl value of the acrylic resin of acrylated preferred 50% is at 20 resin, avoids using solid content is low and hydroxyl value is high acrylate to guarantee the sticking power of printing ink.

The invention has the beneficial effects as follows: the printing-ink of endurance excellence provided by the present invention, the ethanol-tolerant wiping can reach 100-200 time, and the 30-50 of anti-the butanone time, poach did not come off in 1 hour, and hardness still reaches 3H; Tap water soaks and not to come off in 24-48 hour, is a kind ofly all to have the very printing-ink of outstanding advantages at aspects such as color, wear resistance, scratch resistance, chemicals-resistant, soaking-resistant, water boiling resistance.

Embodiment

Following specific embodiment describes the present invention in detail:

Suggestion is diluted with my company's special diluting agent, adds less than 5%;

Should note work-ing life when having added solidifying agent;

Pack with the encloses container tank, not because the release of solvent affects the storage time of printing ink, and might cause the possibility that to use;

Storage requirement: room temp: 20-30 ℃, relative humidity:＜80%, prevent from being exposed to the sun.

Embodiment 1

1, prepare starting material by following parts by weight:

Acrylic resin 58, DBE 10, DPM 10, isophorone 3, toner 10, meteorological silicon-dioxide 3, defoamer 1, dispersion agent 2, silicane adhesion promoter 3.

2, configuration according to the following steps:

1) acrylic resin, aminoresin, ethanol, isophorone, DPM solvent, DBE solvent etc. are pressed umber blanking successively, stir 5 minutes to even, stirring velocity is 800-1000 rev/min.
