Cleaning agent for printing ink

Abstract

The invention discloses a cleaning agent for printing ink. The cleaning agent comprises the following ingredients: 3-7% of oleic acid, 6-10% of isopropanol, 15-25% of solvent oil, 5-15% of 2-ethoxyethanol, 2-5% of fatty alcohol-polyoxyethylene ether sulfate, 1-2.5% of fatty alcohol-polyoxyethylene ether, 0.5-2% of benzotriazole, 0.5-2% of sodium benzoate, 0.5-1.5% of sodium silicate, 0.5-1.5% of ethylene diamine tetraacetic acid tetra-sodium salt, 0.5-1.5% of urea, 0.5-1.5% of sodium gluconate and the balance of water. The cleaning efficiency can reach 99.5% after the four solvents of oleic acid, isopropanol, solvent oil and 2-ethoxyethanol are compounded; fatty alcohol-polyoxyethylene ether sulfate and fatty alcohol-polyoxyethylene ether can generate synergistic interaction, so that a better emulsification effect is achieved, and microemulsion with better stability can be prepared. According to the cleaning agent disclosed by the invention, the excellent cleaning efficiency is ensured, at the same time, the volatility of organic solvents is reduced, the working environment of a printing workshop is improved, and the safety of work is greatly improved.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a cleaning agent for printing ink. Background technique [0002] At present, ink cleaning mainly relies on organic solvents with good volatility, such as gasoline and kerosene. Since the blankets and ink rollers are not pure ink, they contain various components, mainly including binders and pigments, water, phosphoric acid, desiccant, sealing liquid, paper powder and paper wool, etc. Traditional gasoline and kerosene can only dissolve ink The linking material in, but can not wash off the pigment and other components. In addition, these solvents are flammable and explosive. When using these cleaning agents, fire prevention and anti-static are required, and the volatilization of steam and kerosene has caused serious pollution to the public environment and endangered the health of workers. Contents of the invention [0003] The purpose of the present invention is to overco...

AI Technical Summary

Problems solved by technology

Because the blankets and ink rollers are not pure ink, but contain various components, mainly including binders and pigments, water, phosphoric acid, desiccant, sealing liquid, paper powder and paper wool, etc. Traditional gasoline and kerosene can only dissolve ink The linking material in the medium, but can not wash off the pigment and other components

In addition, these solvents are flammable and explosive. When using these cleaning agents, fire protection and anti-static are required, and the volatilization of steam and kerosene has caused serious pollution to the public environment and endangered the health of the staff.
