Problems solved by technology

[0011] The invention patents disclosed above have no problem with the cleaning ability of printing machine ink, but these patent formulations all use high-foaming surfactant monomers, such as: fatty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate, Condensate of hydrogenated castor oil and ethylene oxide, polyoxyethylene sorbitan fatty acid ester, cetearyl alcohol polyoxyethylene ether, coconut oil fatty acid diethanolamide, alkylphenol polyoxyethylene ether, nonylphenol Polyoxyethylene ether, coconut oleic acid alkanolamide, Tween 80, polyoxyethylene lauryl ether, sodium lauryl sulfate, etc.; such post-treatment of ink cleaning requires more water for washing, which will inevitably cause waste of water

Embodiment 1

[0021] Raw material ratio (percentage by weight): 80% isopropanol, 5% limonene, 5% alkyl polyglycoside, 7% monobutyl polyether, 3% sodium laurylalanine.

Embodiment 2

[0023] Raw material ratio (percentage by weight): 70% isopropanol, 10% limonene, 7% alkyl polyglycoside, 8% monobutyl polyether and 5% sodium laurylalanine.

Embodiment 3

[0025] Raw material ratio (percentage by weight): 60% isopropanol, 15% limonene, 9% alkyl polyglycoside, 9% monobutyl polyether and 7% sodium laurylalanine.

[0026] The preparation steps are as follows: in a reaction vessel, sequentially add isopropanol, limonene, alkyl polyglycoside, monobutyl polyether and sodium dodecylalanine; react for 0.5-1 hour, and control the temperature at 10-40 After the reaction is completed, it is lowered to room temperature, and the material is discharged after passing the test. The finished product should be stored in a metal container.

[0027] Preferably, the reaction temperature is 20°C or 30°C.

[0028] Preferably, the reaction time is 1 hour.

Abstract

The invention relates to a production method of a printing rubber roller cleaner. The method is characterized in that the cleaner comprises alkyl polyglucoside, mono-butyl polyether, N-dodecane alanine, limonene and isopropyl. The cleaner is strong in degreasing force and has a particularly strong cleaning effect on oil stains and ink dirt of printing rubber rollers, and clear water can be adopted for after-treatment washing of the printing rubber rollers. The cleaner is a colorless, transparent and low-viscosity liquid in appearance, has the pH value ranging from 6 to 8, has the pleasant aroma and is non-irritating to human skin. After automobile engines are cleaned with the cleaner, hands of cleaning workers are not stained with oil.

Description

technical field [0001] The invention relates to a manufacturing method of a low-foaming printing rubber roller ink cleaning agent, which is characterized in that it is composed of alkyl polyglycoside, monobutyl polyether, N-dodecylalanine sodium, limonene and isopropanol . Background technique [0002] In lithographic printing, fluffy leather rollers were used in the early days, later natural rubber rollers were used, and now synthetic rubber rollers are mainly used; rubber rollers are composed of a rubber layer on the roller surface and a metal roller core, and the roller surface has a certain roughness , smoothness and viscosity, good elasticity, high mechanical strength, small temperature rise during operation, ink resistance, solvent resistance, and weather resistance, but the color change (especially dark color to light color) is not easy to clean. [0003] The rubber roller has a high hardness value, and it is easy to wear the printing plate during printing, which red...
