Technical Field

The invention belongs to the field of chemical cleaning agents, and particularly relates to a mixed type ink cleaning agent.

Background

Ink is commonly used for outer packaging or text printing of various products to enhance the aesthetic appearance of the products to attract the attention of customers. However, when defective products appear in the printing process, the cured ink needs to be cleaned and printed again, so that the aim of recycling finished products and reducing the production cost is fulfilled. The cleaning agent for cleaning the printing ink on the market at present is volatile, has large pollution, poor cleaning effect, strong corrosivity, especially obvious corrosivity on aluminum or aluminum alloy materials, serious corrosion on the metal surface in the repeated cleaning process, thereby losing the significance of reutilization, and potential danger exists in the storage and use processes.

Disclosure of Invention

The invention provides a mixed type ink cleaning agent, and mainly aims to provide an ink cleaning agent which is high in cleaning speed, safe, environment-friendly, free of pollution, free of corrosiveness, good in cleaning effect and good in safety performance.

The invention is realized by adopting the following technical scheme:

the mixed ink cleaning agent is prepared from 40-80% of organic solvent, 5-20% of organic carboxylic acid, 5-20% of organic diluent and 4-9% of liquid wax by volume percentage; the organic solvent is formed by mixing one of dichloromethane, dichloroethane, trichloroethane and tetrachloroethylene with methylal and acetone, the organic carboxylic acid is formic acid or acetic acid, and the organic diluent is ethanol or isopropanol.

Further, the organic solvent is formed by mixing dichloromethane, methylal and acetone.

Further, the organic carboxylic acid is acetic acid.

Further, the organic diluent is ethanol.

Further, the mixed type ink cleaning agent is prepared from 50% of dichloromethane, 18% of methylal, 11% of acetone, 9% of ethanol, 5% of acetic acid and 7% of liquid wax according to volume percentage.

Further, the liquid wax comprises the following components in parts by weight: microcrystalline wax 3 parts and methylcyclohexane 50 parts.

Further, the mixed type ink cleaning agent can be filled into an aerosol tank, and the used propellant is LPG, wherein the mass ratio of LPG: ink cleaner 2: 1.

as can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages: the ink cleaning agent has the advantages of small volatility, low toxicity, environmental protection, no pollution, no corrosion to metal and protection to the cleaning of rubber blankets and rubber rollers; meanwhile, the ink cleaning agent has the advantages of wide raw material source, low price, simple production process and no need of special equipment, so the raw material cost and the preparation cost of the ink cleaning agent can be reduced.
