Ink Synolac prepared by the present invention not only reduces the preparation cost of Synolac, has widened the raw material sources of Synolac, and of light color, the water-repellancy of Synolac and flowing property is excellent, dry speed is fast.
Description
Technical field
The present invention relates to resin for printing ink synthesis field, in particular to a kind of ink Synolac and its preparation method.
Background technology
Current ink adds the body bone that Synolac can improve ink vehicle, be conducive to the wetting of pigment in water resistant simultaneously, therefore much ink and resin producer are all at development quick-dry type waterproof Synolac, but Synolac source is more, and its formula and production technique are not quite similar. The wider medium-to-high grade ink synthetic resins of a kind of purposes obtained through esterification by polyvalent alcohol, polyprotonic acid, lipid acid etc. at present, its raw material derives from refining of petroleum product mostly, plant refines oil, raw materials quality and price are unstable, for widening raw material sources, stable prod price is an important directions of Synolac modification with trench fatty acid oil substituted plant fatty acid oil.
Secondly, the synthetic method of Synolac has solvent method, scorification, fatty acid process and alcoholysis method usually. Wherein scorification uses more, but this method is wayward, and because phthalic anhydride and polyvalent alcohol volatilization are more during pyroreaction, especially when preparing short oil-ity alcohol acid resin, loss of material is too big, and production process is difficult to control, and color of resin is partially dark.
Summary of the invention
It is an object of the invention to provide a kind of ink Synolac and its preparation method, ink Synolac prepared by the present invention not only reduces the preparation cost of Synolac, widen the raw material sources of Synolac, and of light color, the water-repellancy of Synolac and flowing property is excellent, dry speed is fast.
The present invention is achieved in that a kind of ink Synolac, and it is formulated by following ratio of weight and number by following component:
The preparation method of above-mentioned ink Synolac, prepares in accordance with the following methods:
(1) sewer oil lipid acid, linseed oil fatty acid, tetramethylolmethane are dropped in reactor, insulation esterification is carried out at 250 DEG C-270 DEG C, resin is carried out by this insulation esterification reaction process sampling detection, the cooling when the viscosity detecting resin sample reaches 1-2Pa s (25 DEG C);
(2) after temperature of reaction kettle is down to room temperature, add m-phthalic acid and dimethylbenzene, then 250 DEG C-270 DEG C it are warming up to, and lead to into nitrogen, carry out insulation esterification, resin is carried out sampling detection by this insulation esterification reaction process, when the viscosity of detection resin sample is 4-6Pa s (25 DEG C), and during acid value≤below 13mgKOH/g, be cooled to less than 160 DEG C and go out pot.
Described ink Synolac filters and packages with 400-600 mesh filter screen after having prepared.
Ink Synolac of the present invention and its preparation method have the following advantages:
1, with trench fatty acid oil Some substitute vegetable fatty acids, reduce the preparation cost of Synolac, widened the raw material sources of Synolac;
2, adopt tetramethylolmethane, the m-phthalic acid of dryness or water-tolerant to replace glycerine, phthalic anhydride, the Synolac water-repellancy of synthesis and and flowing property excellent, dry speed is faster, can be applicable to high-grade lithographic ink field.
