Problems solved by technology

[0014] From the above search results, it is understood that the open literature has reported a lot of research-related content on rosin-modified phenolic resins. Catalysts include sodium hydroxide, alkali metal lithium compounds, and some weakly basic catalysts or oxide catalysts, such as zinc oxide, calcium acetate, and magnesium oxide, but when the rosin-modified phenolic resin described in the above literature is mixed with mineral oil The performance is not good enough, the solubility of the ink resin prepared by the proposed synthesis method is not satisfactory, and there is still a distance from meeting the requirements of high-quality high-speed printing ink manufacturing for resin quality

Abstract

The invention discloses a complete miscibility phenolic aldehyde modified abietic resin, which can be fully dissolved in petroleum cyclane solvent. The synthetic method comprises the following process steps: (1) adding the alkylphenol, aldehyde and solvent into a reactor, heating, blending and reacting for 4 to 12 hours under the alternating action of acid base catalyst at 65 to 110 degrees C and obtaining the long chain resol; (2) adding the rosin into the reactor, heating and dissolving, and then adding the long chain resol in, reacting with the abietic acid for 5 to 16 hours ar 150 to 270 degrees C and then obtaining the complete miscibility phenolic aldehyde modified abietic resin after adding the polylol in to esterify first and dehydrate then or esterify first and modify then. The complete miscibility phenolic aldehyde modified abietic resin is of much significance for producing the ink which is good for the high speed printing machine.

Description

technical field [0001] The invention relates to a printing ink raw material, especially a phenolic modified rosin resin and a production method thereof. Background technique [0002] With the rapid development of my country's printing industry, the printing ink production technology is changing with each passing day, and the varieties are various. The printing machine has higher and higher requirements for the printing adaptability of the ink. So far, the film-forming substances of oil-based inks mainly use phenolic modified rosin resins. The oil-based ink binder system composed of phenolic modified rosin resin, vegetable oil, and mineral oil is still the mainstream of ink production. The properties that resins with different properties bring to the ink binder system are very different, so that the ink can form printing adaptability with different characteristics. The popularization of high-speed printing machines has brought a series of problems to be solved, such as emul...
