Problems solved by technology

[0004] However, the current commercially available plate cleaning solution only has the function of removing oil stains on the plate, and cannot protect and repair the plate to a certain extent.
Moreover, the antibacterial performance of the existing plate cleaning solution itself is relatively poor, which affects its mission of use.

Embodiment 1

[0030] A printing plate decontamination and scratch double-effect cleaning liquid, prepared from the following components by weight: 1.0 parts of gum arabic, 0.5 parts of polyvinyl alcohol, 0.8 parts of hydroxyethyl cellulose, and 0.53 parts of nanopotassium Feldspar powder, 0.7 part sodium dodecylbenzene sulfonate, 0.3 part castor oil, 0.2 part squalane, 0.7 part repair aid, 0.4 part dimethyl sulfate, 0.32 part dextrin, 0.3 part citric acid, 1.0 part Phosphoric acid, 0.4 parts of triethanolamine, 0.4 parts of D-mannitol and 40 parts of deionized water.

[0031] The preparation method of repair auxiliary agent comprises the following steps:

[0032] Ⅰ. Accurately weigh the appropriate amount of tetraethyl silicate, dimethyldimethoxysilane and absolute ethanol according to the ratio of the amount of substances to 1:0.25:6. Transfer to an ice-water bath, and then add an appropriate amount of acid solution to the mixed solution while stirring, so that the acid solution and the m...

Embodiment 2

[0045] The printing plate decontamination and scratch removal double-effect plate cleaning solution provided in this embodiment and the preparation method are roughly the same as in Example 1, the main difference is that the proportioning of each raw material is different, specifically:

[0046] 1.2 parts of gum arabic, 0.6 parts of polyvinyl alcohol, 1.0 parts of hydroxyethyl cellulose, 0.6 parts of nano potassium feldspar powder, 0.9 parts of sodium dodecylbenzenesulfonate, 0.38 parts of castor oil, 0.3 parts of squalane, 1.0 parts Repair aid, 0.45 parts of dimethyl sulfate, 0.35 parts of dextrin, 0.32 parts of citric acid, 1.2 parts of phosphoric acid, 0.45 parts of triethanolamine, 0.5 parts of D-mannitol and 45 parts of deionized water.

Embodiment 3

[0048] The printing plate decontamination and scratch removal double-effect cleaning solution provided in this embodiment and the preparation method are roughly the same as in Example 1, the main difference is that the proportioning of each raw material is different, specifically:

[0049] 1.5 parts of gum arabic, 0.8 parts of polyvinyl alcohol, 1.3 parts of hydroxyethyl cellulose, 0.65 parts of nano potassium feldspar powder, 1.2 parts of sodium dodecylbenzenesulfonate, 0.45 parts of castor oil, 0.4 parts of squalane, 1.2 parts Repair aid, 0.5 part of dimethyl sulfate, 0.38 part of dextrin, 0.35 part of citric acid, 1.5 part of phosphoric acid, 0.5 part of triethanolamine, 0.7 part of D-mannitol and 50 parts of deionized water.

Abstract

The invention relates to the technical field of PS / CTP printing, in particular to a printing plate decontamination and scratch removal double-effect plate cleaning liquid and a preparation method thereof; it is prepared from the following component raw materials in parts by weight: 1.0 to 1.5 parts of gum arabic , 0.5-0.8 parts of polyvinyl alcohol, 0.8-1.3 parts of hydroxyethyl cellulose, 0.53-0.65 parts of nano potassium feldspar powder, 0.7-1.2 parts of sodium dodecylbenzenesulfonate, 0.3-0.45 parts of castor oil, 0.2- 0.4 parts of squalane, 0.7-1.2 parts of repair aids, 0.4-0.5 parts of dimethyl sulfate, 0.32-0.38 parts of dextrin, 0.3-0.35 parts of citric acid, 1.0-1.5 parts of phosphoric acid, 0.4-0.5 parts of triethanolamine, 0.4-0.7 parts of D-mannitol and 40-50 parts of deionized water; the plate cleaning solution prepared by the present invention not only has good decontamination and antibacterial functions, but also can protect and repair the surface of the printing plate to a certain extent The effect of scratches on the surface ensures the safety and quality of the printing plate.

Description

technical field [0001] The invention relates to the technical field of PS / CTP printing, in particular to a printing plate decontamination and scratch removal double-effect cleaning solution and a preparation method thereof. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, leather and other materials through the processes of plate making, ink application, and pressure to reproduce the contents of the original manuscripts in batches. In a simple sense, printing is a process technology that uses printing plates or other methods to transfer the graphic information on the original manuscript to the substrate. It can also be understood as the use of analog or digital image carriers to transfer colorants / colorants (such as ink ) is transferred to the reproduction process on the substrate. [0003] Currently, plate cleaning solutions are often used in the printing field. Plate cleaning solution is a kind of PS plate / CTP...
