Problems solved by technology

Among them, the melting method is widely used, but this method is not easy to control, because phthalic anhydride and polyols volatilize more during high temperature reaction, especially in the preparation of short oil alkyd resin, the material loss is too large, and the production process is difficult to control, the resin color deep

specific Embodiment approach

[0016] A kind of alkyd resin for printing ink, it is formulated by following component by weight ratio:

[0017]

[0018] The preparation method of alkyd resin for above-mentioned printing ink is prepared according to the following method:

[0019] (1) Put waste oil fatty acid, linseed oil fatty acid, and pentaerythritol into the reaction kettle, and carry out a heat preservation esterification reaction at 250°C-270°C. During the heat preservation esterification reaction, the resin is sampled and detected. When detecting the viscosity of the resin sample Cool down when it reaches 1-2Pa·s (25℃, 1000rpm);

[0020] (2) After the temperature of the reactor is lowered to room temperature, add isophthalic acid and xylene, then raise the temperature to 250°C-270°C, and feed nitrogen to carry out the esterification reaction of heat preservation, during the esterification reaction of heat preservation The resin is sampled and tested. When the viscosity of the resin sample is 4-6Pa·...

Abstract

The invention relates to an alkyd resin for ink and a preparation method of the alkyd resin. The alkyd resin for the ink is prepared from the following components in parts by weight: 7-9 parts of pentaerythritol, 2-10 parts of hogwash oil fatty acid, 60-70 parts of linseed oil fatty acid, 10-20 parts of isophthalic acid and 10-30 parts of dimethylbenzene reflux quantity. According to the prepared alkyd resin for the ink, the preparation cost of the alkyd resin is reduced, the material source of the alkyd resin is widened, and the alkyd resin is light in color, excellent in water resistance and flowing property, and quick in drying speed.

Description

technical field [0001] The invention relates to the field of resin synthesis for ink, in particular to an alkyd resin for ink and a preparation method thereof. Background technique [0002] At present, adding alkyd resin to the ink can improve the body of the ink linking material, which is beneficial to the wetting of the pigment while resisting water. Therefore, many ink and resin manufacturers are developing quick-drying waterproof alkyd resin, but alkyd resin There are many sources, and its formula and production process are not the same. At present, a kind of synthetic resin for medium and high-end inks is obtained by esterification of polyols, polyacids, fatty acids, etc., and its raw materials are mostly derived from petroleum processed products and plant refined oils. The quality and price of raw materials are unstable. The source of raw materials, stable product prices, and the replacement of vegetable oil fatty acids with waste oil fatty acids are an important dire...
