Embodiment 1

[0042] Put 0.1mol of phthalic anhydride, 0.89mol of triethylene glycol, 0.1mol of ethanol and 0.005mol of concentrated sulfuric acid into a 500ml four-neck flask equipped with a reflux condensing tube, and pass through an inert gas protection, stir and raise the temperature to 100-160°C for reaction After 12 hours, the by-product was evaporated under reduced pressure, and after cooling, 300ml of ether was added to precipitate and wash to obtain a colorless to light yellow liquid, which was a polyhydroxyl hyperbranched polymer. The yield was 94%, and the weight-average molecular weight was 1750. The molecular weight distribution is 2.2.

Embodiment 2

[0044] Under the same reaction condition of embodiment 1, drop into 0.1mol benzene tetracarboxylic acid and 1.34mol4-hydroxyl isophthalic acid, obtain white solid, be polycarboxy hyperbranched polymer, yield is 92%, weight-average molecular weight is In 2000, the molecular weight distribution was 2.8.

Embodiment 3

[0046] Select 0.1 mol and 0.8 mol of soybean oil from Example 1 and put them into a 500ml four-necked flask, pass inert gas protection, stir and raise the temperature to 140°C for 10 hours to obtain an amber liquid with an acid value of 35mgKOH / g and a viscosity of 0.5PaS , the weight average molecular weight is 5500, and the molecular weight distribution is 3.5. (Infrared spectrum see figure 1 ).

Abstract

The invention discloses a synthesis method and preparation process of hyperbranched polymer resin for intaglio ink. A hyperbranched polymer connection material for the intaglio ink can reduce the contents of volatile organic solvents (VOC) in the ink, can promote the bonding firmness between paper and ink, and meets the ink requirement and the printing adaptability of intaglio printing. The hyperbranched polymer resin has the advantages of good storage stability, shallow color, moderate fixing time and the like; and the prepared intaglio ink has good printing adaptability, drying property, materialization resistance and machine washing resistance; moreover, the contents of the VOC are reduced effectively. The connection material has a structure general formula described in the specification.

Description

technical field [0001] The invention relates to a vehicle for engraving gravure printing ink. Background technique [0002] As the laws and regulations on environmental protection in various countries in the world are increasingly standardized and perfected, such as REACH, RoHS and GHS of the European Union, the environmental protection industry standard of the People's Republic of China HJ / T 371-2007, and the strict requirements of on-site operators on the operating environment, ink Environmental protection issues are increasingly concerned, and the development of gravure inks with low organic solvent (VOC) content has attracted the attention and research of domestic and foreign industries. [0003] At present, the binder made of soybean oil, tung oil, linseed oil, castor oil, tall oil and other vegetable oil modified alkyd resins has been widely used in engraving gravure inks, but the existing engraving gravure inks contain high volatile non-toxic organic solvents. These...
