Embodiment 1

[0011] Rosin improved phenolic resin: take 2100 parts of p-octylphenol to dissolve, add 90 parts of 25% caustic soda solution, 160 parts of 37% formaldehyde, and react at 55°C for 8 hours to obtain the initial condensation product of phenolic resin; take 750 parts of rosin, Malay 30 parts of acid anhydride and 250 parts of initial condensate of phenolic resin were placed in a reactor, under the protection of nitrogen flow, stirred and reacted at 180-200°C for 3 hours, then added 106 parts of pentaerythritol and 16 parts of glycerin, and reacted at 200-270°C until acid When the value reaches 15-20, the rosin-improved phenolic resin is obtained.

[0012] Alcohol-based resin coating: Take 17 parts of rosin modified phenolic resin, 7 parts of kaolin, 10 parts of carbon black, 0.2 parts of preservative (such as SJ1006 of Tengzhou Anticorrosion Technology Co., Ltd.), 0.4 parts of dispersant (such as BYK K-163) , 36 parts of ethanol, 5 parts of isopropanol. First heat and dissolve t...

Embodiment 2

[0014] Alcohol-based resin paint: Take 15 parts of rosin-improved phenolic resin, 5 parts of sodium carbonate, 6 parts of pigment, 0.1 part of preservative, 0.3 part of dispersant, and 50 parts of ethanol. First heat and dissolve the rosin-improved phenolic resin in ethanol, then add other components in sequence, and use a grinder to disperse the system evenly, and the particle size should be below 10 μm.

Embodiment 3

[0016] Alcohol-based resin coating: 20 parts of rosin modified phenolic resin, 10 parts of aluminum hydroxide, 15 parts of pigment, 0.3 part of preservative, 0.5 part of dispersant, 40 parts of n-butanol. First heat and dissolve rosin-modified phenolic resin in n-butanol, then add other components in sequence, and use a grinder to disperse the system evenly, and the particle size should be below 10 μm.

Abstract

The invention discloses an alcohol-based resin coating. The alcohol-based resin coating comprises the following components in parts by weight: 15-20 parts of rosin modified phenol resin, 5-10 parts of filler, 6-15 parts of pigment, 0.1-0.3 part of preservative, 0.3-0.5 part of dispersing agent and 40-50 parts of solvent; and the solvent is an alcohol type solvent. The resin coating prepared according to the invention has the advantages of better resistance to emulsification, stability, fixation and dryness, as well as stronger wettability and color emissivity to the pigment.

Description

technical field [0001] The invention relates to a resin coating, in particular to an alcohol-based resin coating for ink. Background technique [0002] Printing ink is a fine chemical product that transmits information and decorates the cultural world. Both the ink industry and the printing industry develop with the prosperity of the national economy and the development of cultural and educational undertakings. The technical progress and production of ink are to some extent one of the signs of the cultural development of the region. [0003] Traditionally, vegetable oil is used as a binder to prepare inks. With the advancement of industrial technology, various types of resins have gradually replaced vegetable oils and introduced into the field of ink binders. However, most inks currently use toxic benzenes, ketones, ethers, etc. as solvents, which are harmful and affect the environment. Contents of the invention [0004] The object of the present invention is to provid...
