Problems solved by technology

However, using toner as the consumable for laser blueprint printing is generally supplied in the form of toner cartridges, which is expensive. After a single toner cartridge is used up, it is difficult to recycle, which will cause a lot of waste of resources and environmental pollution. In addition, the size of the toner cartridge is directly related to the price. , that is to say, the larger the size of the toner cartridge, the higher the cost. At present, the existing blueprint toner can only print No. 0 drawings at most, which cannot meet the larger printing width requirements of engineering blueprints.

preparation example Construction

[0032] The preparation method of oil-based ink of the present invention comprises the following steps:

[0033] 1) Put the above components except the pigment into the dispersion tank in turn, and stir for 20 minutes at 200-500r / min until the material is uniform;

[0034] 2) Slowly add the pigment under the stirring state of 200r / min. After the mixing is completed, adjust the rotation speed to 800-1200r / min and disperse for 30-60min until the mixture is uniform;

[0035] 3) Send the dispersed mixed solution to a sand mill to grind until the particle size D50 is less than 150nm, and send the ground mixed solution to a centrifuge for centrifugation to remove impurities. The specific parameters of the centrifuge are set as: flow rate 20-50L / h , the rotation speed is 5000~20000r / min, and then filtered with 0.5μm filter paper, that is.

Embodiment 1

[0037] An oil-based ink for engineering blueprint printing, which includes the following components by mass percentage:

[0038]

[0039] The preparation method of this oil-based ink is as follows:

[0040] Put the above components except the pigment Paliogen L6360 into the dispersion tank in turn, adjust the speed to 500r / min, stir for 20min until the material is uniform; slowly add the pigment PaliogenL6360 under the stirring state of 200r / min, adjust the speed after the mixing is completed Disperse at 1200r / min for 45 minutes until evenly mixed; transport the dispersed mixed solution to a sand mill for grinding until the particle size D50 is less than 150nm, and transport the ground mixed solution to a centrifuge for centrifugation to remove impurities. The specific parameters of the centrifuge are set It is: the flow rate is 35L / h, the rotation speed is 12000r / min, and then filtered with 0.5μm filter paper.

Abstract

The invention discloses oil-based ink for engineering blueprint printing and a preparation method thereof, and belongs to the technical field of the digital ink-jet. The oil-based ink comprises the following components by mass percent: 60-80% of an alkane solvent, 5-20% of a volatilization-resistant assistant, 3-15% of a dispensing agent, 0.1-1% of a flatting agent, and 3-20% of pigment. The preparation method comprises the following steps: successively adding other components except the pigment into a dispersing cylinder, stirring for 20 min until the materials are uniformly mixed; slowly adding the pigment in the stirring state, after mixing the materials, dispersing for 30-60 min until the materials are uniformly mixed; grinding the dispersed mixed liquid until the particle size D50 is smaller than 150 nm, centrifuging the grinded mixed liquid and removing impurities, and filtering to obtain the oil-based ink. The prepared oil-based ink is applied for the engineering blueprint printing. The character line of the obtained finished product blueprint is sharp, clear, light-resistant, water-resistant, and scrubbing-resistant. The using requirement can be completely satisfied. The quality of the finished product is good.

Description

technical field [0001] The invention relates to the technical field of digital inkjet, in particular to an oil-based ink used for engineering blueprint printing and a preparation method thereof. Background technique [0002] Engineering blueprint drawings are widely used in R&D and design work in the fields of machinery and architecture. During the storage of files, engineering blueprint drawings have the advantage of long storage time and can prevent illegal modification of drawings. [0003] The traditional production method of engineering blueprints is mainly the diazonium salt imaging method, which was invented in the early 19th century and gradually became widely used, becoming the most commonly used process for printing pictures. Drawings made by the diazonium salt imaging method show dark lines on a white background, and the operation process is as follows: 1. Photosensitization: photosensitize the paper with a mixture of diazonium salts (used in dye production), reac...
