Embodiment 1

[0014] Embodiment 1: contains the following components by weight percentage: 25 parts of polyurethane resin, 6 parts of aldehyde and ketone resin, 28 parts of rutile titanium dioxide, 0.2 part of fumed silica, 5 parts of propylene glycol ethyl ether, 15.8 parts of ethanol, 11.9 parts of isopropanol , 0.1 part of fluorescent whitening agent, 8 parts of butyl acetate, mix the components and stir evenly to obtain the PD type alcohol-soluble printing composite ink of the present invention.

Embodiment 2

[0015] Embodiment two: contain the following components by weight percentage: 22 parts of polyurethane resins, 7 parts of aldehyde and ketone resins, 30.6 parts of rutile titanium dioxide, 0.3 parts of fumed silica, 5 parts of propylene glycol ethyl ether, 16 parts of ethanol, 11 parts of isopropanol , 0.1 part of fluorescent whitening agent, 8 parts of butyl acetate, mix the components and stir evenly to obtain the PD type alcohol-soluble printing composite ink of the present invention.

Embodiment 3

[0016] Embodiment three: contain the following components by weight percentage: 26.7 parts of polyurethane resin, 5 parts of aldehyde and ketone resin, 26 parts of rutile titanium dioxide, 0.1 part of fumed silica, 6 parts of propylene glycol ethyl ether, 15 parts of ethanol, 12 parts of isopropanol , 0.2 parts of fluorescent whitening agent, 9 parts of butyl acetate, mix the components and stir evenly to obtain the PD type alcohol-soluble printing composite ink of the present invention.

[0017] The above-mentioned fumed silica is also called fumed white carbon black, English name: Silicon Dioxide, molecular formula: SiO2, it is white fluffy powder, porous, non-toxic, tasteless, pollution-free, high temperature resistant. At the same time, its chemical inertness and special thixotropic properties can significantly improve the tensile strength, tear resistance and wear resistance of rubber products, and the strength of rubber can be improved by dozens of times. Rheological and...

Abstract

The invention discloses PD type alcohol soluble printing composite oil ink, which comprises the following components in part by weight: 22 to 30 parts of polyurethane resin, 5 to 7 parts of ketonealdehyde resin, 24 to 32 parts of rutile type titanium dioxide, 0.1 to 0.4 part of fumed silicon dioxide, 4 to 6 parts of propylene glycol monoethyl ether, 14 to 16 parts of ethanol, 10 to 13 parts of isopropanol, 0.1 to 0.3 part of fluorescent brightener and 7 to 9 parts of butyl acetate. The oil ink disclosed by the invention has the advantages that: the oil ink does not contain benzene and ketone, contains less residual solvent, and meets national requirements on food sanitation; the color of the oil ink is bright; the dot repeatability is high; the levelling property is high; the oil ink is particularly suitable for chromaticity printing and can be printed on flexible boards; and printability of the oil ink is high.

Description

[0001] 【Technical field】 [0002] The invention relates to ink, in particular to a PD type alcohol-soluble printing composite ink. 【Background technique】 [0003] Existing printing inks generally contain chemical substances such as benzene and ketones, which are easy to cause pollution in packaging and printing production, and are especially not suitable for food packaging and printing. 【Content of invention】 [0004] Aiming at the above-mentioned defects of the prior art, the present invention provides an environmentally friendly ink that does not contain benzene and ketone——PD type alcohol-soluble printing composite ink. [0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: [0006] A PD type alcohol-soluble printing composite ink, which contains the following components by weight percentage: 22-30 parts of polyurethane resin, 5-7 parts of aldehyde and ketone resin, 24-32 parts of rutile tit...
