Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment, but can not be regarded as limitation of the present invention.

[0026] A kind of colloidal oil formula of the present invention (below all is mass percentage) is as follows:

[0027] Phenolic resin: 42%

[0028] Linseed oil: 25%

[0029] Mineral oil: 32%

[0030] Liquid gelling agent: 1%

[0031] The manufacturing process of gum oil of the present invention is as follows

[0032] After the resin is qualified, add vegetable oil, raise the temperature to 230-235°C, keep it warm for 30 minutes, then put it into the thinning tank and start stirring, control the temperature at 210°C, add ink oil to adjust the viscosity, and add additives at 170-175°C after the pass is completed Finally, the temperature is kept at 170°C for 30-60 minutes, and then the indicators are tested, and the pot is qualified.

[0033] The gum oil of the present invention is mainly used in the manufacture of off...

Abstract

The invention relates to a formula, a preparation technology and an application of gummy oil. The formula of the gummy oil comprises, by mass, 30-40% of resin, 15-20% of plant oil, 30-40% of ink oil and 1-5% of an assistant 1#, wherein the resin can be one of phenolic resins and octyl phenol resins; the plant oil is linseed oil; the ink oil is mineral oil; and the assistant 1# is a liquid gellant. The preparation technology of the gummy oil concretely comprises the following steps: adding the qualified resin into the plant oil, heating to 230-235DEG C, carrying out heat insulation for 30min, pumping the above obtained mixture into a letdown tank, stirring, adding the ink oil at 210DEG C to adjust the viscosity, adding the assistant at 170-175DEG C, carrying out heat insulation at 170DEG C for 30-60min, detecting indexes, and taking the obtained gummy oil out of the tank after the gummy oil is qualified. The gummy oil can be applied to prepare offset printing ink. The gummy oil has the advantages of strong luster, fast fixation speed, low cost, good wear resistance and cost saving.

Description

technical field [0001] The invention belongs to an ink connecting material-colloidal oil formula and a preparation process thereof. Background technique [0002] Colloidal oil is used in the manufacture of offset printing ink. The existing colloidal oil has high cost, poor printing performance, and complicated preparation process, so that the ink produced by it has slow fixing speed and poor scratch resistance. [0003] At present, colloidal oil is mainly composed of phenolic resin, vegetable oil, mineral oil, additives and other substances. The preparation method adopts a two-step method: put phenolic resin oil, etc. into the reactor and heat up to 50-75 ° C, add additives and stir evenly Afterwards, heat up to 90°C and keep warm for 1 hour, then heat up to 150-170°C, keep warm for 30 minutes, and form a transparent gel, which is passed the test and taken out of the pot. This method has low efficiency and high cost. Contents of the invention [0004] In order to solve t...
