Problems solved by technology

[0003] At present, the widely used alkyd resin in ink industry, such as the technology disclosed in Chinese Patent Application No. 00115590.3, is generally a vegetable oil-modified m-phenyl / o-phenyl alkyd resin with medium and long oil degree, which has poor hydrophilicity and is not resistant to alkali. Moreover, it cannot be self-emulsified, and an emulsifier needs to be added during use, thus limiting its scope of application, especially not for the preparation of water-rub engraved gravure inks that require better alkali resistance.

Embodiment 1

[0042] mn

Embodiment 2

[0044] Adopt the method for embodiment 1, cool down to 250 DEG C after insulated for 35 minutes, add 22 kilograms of C having a boiling range of 200~210 DEG C 12 Linear alkane solvent, then add other raw materials to prepare ink, the formula is as follows:

[0045] Self Emulsifying Alkyd 10%

[0046] Gelled High Acid Value Phenolic Resin Oil 25%

[0047] Phenolic resin oil 10%

[0048] Pigment: 8%

[0049] CaCO 3 : 35%

[0050] TiO 2 :2%

[0051] BaSO 4 : 5%

[0052] Cobalt isozincate (desiccant): 1%

[0053] Solvent (C12 alkanes): 4%

[0054] That is, inks for printing intaglio engravings of securities are obtained.

Embodiment 3

[0056] The ink of Example 2 is tested for alkali resistance: the prepared ink is coated on a sample strip, and immersed in 2% NaOH aqueous solution for 0.5 hour, taken out, rinsed, and air-dried for rating.

[0057] The ink of embodiment 2 is carried out the release speed of solvent is tested, and its result sees figure 1 . Among the figure, curve 1 is the data of embodiment 2.

Abstract

This invention discloses a kind of selfemulsifying alkyd resin and its producing method. This invention chooses compounds of many kinds of polyalcohols and organic acid as its raw material, adopts epoxy group and non-hydroxy and non-carboxyl hydrophile gene into the alkyd, enlarges the structure of rosin, improves its alkali tolerance, reduces the acid price of the rosin and has strong hydrophilicity and selfemulsifying. When confecting printing ink, you don't need to add emulsifying agent, which decrease the production cost. It possesses relatively good alkali tolerance and has better emit than ordinary alkyd resin. It is a kind of ideal printing ink of intaglio printing.

Description

technical field [0001] The invention relates to an alkyd resin and a preparation method thereof, in particular to a self-emulsifiable alkyd resin and a preparation method thereof. Background technique [0002] Alkyd resin is a very important chemical product, which has a wide range of uses in ink, coating and other fields. [0003] At present, the widely used alkyd resin in ink industry, such as the technology disclosed in Chinese Patent Application No. 00115590.3, is generally a vegetable oil-modified m-phenyl / o-phenyl alkyd resin with medium and long oil degree, which has poor hydrophilicity and is not resistant to alkali. And can not self-emulsify, need to add emulsifying agent during use, therefore limit its scope of application, especially can not be used for preparing the water rub engraving gravure ink that needs alkali resistance better. Contents of the invention [0004] The technical problem to be solved in the present invention is to disclose a self-emulsifiabl...
