Embodiment 1

[0042] Weigh 20 kg of phenolic resin, 20 kg of alkyd resin, 30 kg of calcium carbonate, and 8 kg of organic toner according to their weight, put them into the material bucket, and then stir for 30 minutes. The three-roller ink machine is rolled to make its fineness≤15 μm; then add 8 kilograms of particle size distribution and be the microspherical structure of Canaba wax of 10-20 μm, 10 kilograms of solvents (4 kilograms of diethylene glycol monoethyl ether And 6 kilograms of boiling points are the petroleum solvent of 200-280), 2 kilograms of manganese octoates, 2 kilograms of potassium dodecylbenzenesulfonate are stirred together with the rolled material, and the stirring time is 20 minutes, after stirring evenly. The electron micrograph of the canaba wax with microsphere structure is shown in figure 1 . Adopt above-mentioned abrasion resistance detection method to detect, its result sees figure 2 . In the figure, the ground spline 1 refers to the tested spline, and the ...

Embodiment 2

[0044] Weigh 40 kg of phenolic resin, 8 kg of alkyd resin, 30 kg of calcium carbonate, and 8 kg of organic toner according to their weight, put them into the material bucket, and then stir for 30 minutes. The three-roller ink machine is rolled to make its fineness≤15 μm; then add 3 kilograms of polyethylene wax and 2 kilograms of beeswax and 7 kilograms of solvent (3 kilograms of diethylene diethylene glycol) with a microspherical structure of 20-35 μm in particle size distribution. Alcohol monoethyl ether and 3 kilograms of petroleum solvents with a boiling point of 200-280), 2 kilograms of zirconium naphthenate, are stirred together with the rolled material, and the stirring time is 20 minutes, after stirring evenly. Test result is identical with embodiment 1.

Embodiment 3

[0046] Using the same formula and process as in Example 2, but adding 1.5 kg of zirconium naphthenate and 0.5 kg of nonylphenol polyoxyethylene ether, the detection result is the same as in Example 1.

Abstract

A printing ink with excellent wear-resisting ability is prepared by utilizing wax in which microspherulitized structure is applied. The wax in micro spherulitized structure has comparatively large specific surface area so it is easy to be mixed and dispersed in printing ink to reduce friction coefficient of ink film surface for improving wear-resisting ability of the printing ink.

Description

technical field [0001] The invention relates to an ink, in particular to an ink for engraving gravure. Background technique [0002] Engraving gravure ink is thicker, use conventional ink, as the technology disclosed in Chinese Patent Application No. 01144965.9, the wax that this technology adopts is conventional polyethylene wax, oxidized polyethylene wax, Kanaba wax, polytetrafluoroethylene wax, Paraffin, after drying the conjunctiva, the surface of the ink will wrinkle, which will affect the wear resistance of the ink. After the ink is printed on the printed matter, due to poor wear resistance, the printed matter will have ink shedding and ink loss during use, which will cause the printed matter to lose its original printing effect. Contents of the invention [0003] The technical problem to be solved in the present invention is to disclose an ink for engraving gravure with good wear resistance, so as to overcome the defect of poor ink performance in the prior art. ...
