Problems solved by technology

[0002] In the process of offset printing, the viscosity of the ink has a great influence on the printing quality. When the viscosity of the ink is too high, the ink scraping effect is poor, the transferability is poor, and it is easy to pattern, resulting in the phenomenon of roughening and powder removal of the paper. In actual use In the process, it is necessary to use a viscosity reducer to reduce the viscosity of the ink. The commercially available viscosity reducer is mainly composed of petroleum jelly, waxes and oils. However, this type of viscosity reducer has a narrow range of use and the production process is not environmentally friendly.

Embodiment

[0012] The viscosity reducing agent of the present embodiment is made from the following raw materials in parts by weight: palm oil 15, snake oil 6, glycerin 15, alkyd resin 10, fresh pomelo peel ethanol extract 0.1, polyethylene glycol monomethyl ether 2, alkane Base dimethyl polysiloxane 2, auxiliary agent 1.

[0013] The auxiliary agent is made of the following raw materials in parts by weight: 600 mesh talc powder 2, glycerin 4, emulsified silicone oil 2 with a solid content of 60%, sodium hypophosphite 0.2, deionized water 5, the preparation method is: first hypophosphite Dissolve sodium in deionized water, then add talc powder, put the obtained material into a grinder and grind for 40 minutes, dry the obtained material completely at 60-80°C, then put it into glycerin, and stir at high speed until it is evenly dispersed in glycerin , and finally add emulsified silicone oil, continue to stir and disperse for 1.5h, that is.

[0014] The preparation method of this viscosity...

Abstract

The invention relates to the technical field of offset printing, and particularly relates to an ink viscosity depressant containing snake oil and a preparation method of the ink viscosity depressant. The viscosity depressant is prepared from the following raw materials in parts by weight: 12-15 parts of palm oil, 5-8 parts of snake oil, 15-20 parts of glycerinum, 10-12 parts of alkyd resin, 0.1-0.2 part of fresh pomelo peel ethanol extracting solution, 2-3 parts of methoxy polyethylene glycol, 1-2 parts of alkyl dimethyl polysiloxane and 1-2 parts of an adjuvant. The viscosity depressant disclosed by the invention does not contain volatile toxic substances such as mineral oil and the like, replaces commonly used Vaseline with the snake oil, and can quicken the bonding speed of the viscosity depressant and the ink, so that the effect of reducing the ink viscosity is achieved. The fresh pomelo peel ethanol extracting solution is capable of effectively preventing lipid substances from being oxidized, and prolonging the storage time, and is combined with the ingredients such as alkyl dimethyl polysiloxane, adjuvant and the like, so that the ink viscosity and the mobility can be effectively improved, and the printing effect is improved.

technical field [0001] The invention relates to the technical field of offset printing, in particular to an ink viscosity reducer containing snake oil and a preparation method thereof. Background technique [0002] In the process of offset printing, the viscosity of the ink has a great influence on the printing quality. When the viscosity of the ink is too high, the ink scraping effect is poor, the transferability is poor, and it is easy to pattern, resulting in the phenomenon of roughening and powder removal of the paper. In actual use Among them, it is necessary to use a viscosity reducer to reduce the viscosity of the ink. The commercially available viscosity reducer is mainly composed of petroleum jelly, waxes and oils. However, this type of viscosity reducer has a narrow range of use and the production process is not environmentally friendly.
