Example Embodiment

[0009] The technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0010] The benzene-free diluent is as follows: ethyl acetate 40%-50% (weight ratio), butanone ratio accounts for 35%-45% (weight ratio), isopropanol ratio accounts for 10%-20% (weight ratio) Prepared. Among them: ethyl acetate CH3COOC2H5, boiling point 77℃, strong solubility for the ink resin of the ink system, strong volatility; methyl ethyl ketone CH3CH2COCH3, boiling point 73.4℃, strong solubility for the ink resin of this system, general volatility; isopropanol C3H8O has a boiling point of 82.4°C. The ink resin of this system has general solubility and poor volatility. Among them, ethyl acetate is a true solvent, which can dissolve the resin; isopropanol is a false solvent to ensure the fluidity of the ink; methyl ethyl ketone is a true solvent, which can dissolve the resin and will not cause the viscosity of the ink to increase due to too fast vola

Abstract

The invention discloses diluent without benzene, in particular to the diluent which does not contain the benzene and is used for manufacturing painting ink. The diluent without the benzene is formed by preparation of ethyl acetate, butanone and isopropanol. The diluent without the benzene passes test of specific resin gravure printing ink, raw materials of the specific resin gravure printing ink and samples. An optimize formula is obtained. The prepared painting oil is good in adaptability and capable of meeting requirements of actual printing production due to the fact that the diluent without the benzene matches with the actual plastic gravure printing technology. The diluent without the benzene has the advantages of being environment-friendly, free from the benzene, and capable of enabling the prepared printing oil to keep the original printing effect and quality.
