Publication number CN 1597802A
After searching, we I learned that some reports on plastic ink diluents have been published in the public literature. For example, Chinese patent
50% to 70% of at least one of toluene, xylene and pure benzene
120#+[#] Solvent: 5% to 30% of at least one of gasoline, methanol, ethanol, mixed propanol and butanol
Butyl ester, ethyl ester, butyl acetate and at least one of ethyl acetate 5% to 30%
5% to 20% of at least one of cyclohexanone, ethylene glycol ether acetate, acetone, butanone and distilled water
All percentages are by weight. The composition of the present invention is uniformly mixed by a general method, such as adding each component into a container at the required content and stirring evenly.
The main component of the ink diluent reported in the above-mentioned public literature contains toxic benzene and its compounds. Although this type of ink diluent has stable dilution effect, high volatility and solubility, and low production cost, However, because its raw materials contain toxic substances such as benzene or benzene compounds, and this type of ink diluent does not emphasize its specific use and pertinence, if used in food processing, it will cause harm to human health and the environment. It can also cause pollution.
Content of the invention
In the long-term work practice and scientific research, the inventor has made full use of the existing Based on the ink diluent technology platform, we conducted research on non-toxic formulas for plastic ink diluents and overcame the technical problem of benzene poisoning caused by adding toxic substances benzene and its derivatives to the ink diluent. A benzene-free plastic ink diluent that replaces benzene and its derivatives in the ink diluent with other low-priced and good diluting substances.
The purpose of the present invention is to provide a plastic ink diluent that does not contain benzene and its derivatives. This diluent avoids and eliminates the occurrence of poisoning by benzene or benzene derivatives and has good dilution effect. It has high volatility and solubility, low production cost, wide range of use, wide source of raw materials, low price and aromatic smell.
The technical solution of the present invention is achieved as follows:
The benzene-free plastic ink diluent is composed of hydrocarbon solvents and turpentine, ethyl acetate, propyl acetate, and butyl acetate. Its composition and volume percentage are as follows:
Turpentine 2-15%
Ethyl acetate 20-40%
Propyl acetate 1-10% < /p>
Butyl acetate 1-5%
Hydrocarbon solvent balance
The hydrocarbon solvent mentioned above should be 90# gasoline or 93# gasoline or 97# Any kind of gasoline, or their mixture; the turpentine should be of high quality.
The function of the above-mentioned hydrocarbon solvents is to dilute, reduce the viscosity of the resin, and make the resin fluid; turpentine has better compatibility with the resin, making the printing ink more lubricant and also has an aromatic smell. ; Ethyl acetate is also a solvent for paints, artificial leather, etc., and is also a raw material for basic organic synthesis of pharmaceuticals, dyes, spices, etc. Adding ethyl acetate can make the ink diluent have resistance to a variety of resins, hydrocarbon solvents and lower alcohols It has better compatibility and can adjust its volatilization speed; propyl acetate is a mild and quick-drying agent that can be used as an elastic and gravure printing ink, especially in polyolefin and polyamide film printing; butyl acetate is an important It is a spice that naturally exists in apples, bananas, pears and other fruits. It has a strong banana smell and is an edible spice allowed to be used in GB2760-86. It is used in the preparation of fruit-based flavors. It is also used in chemical, pharmaceutical, biological, etc. Industrial raw materials and excellent organic solvents. The present invention uses butyl acetate, on the one hand, it is used to dissolve resin, and on the other hand, it also makes the diluent have a strong fragrance.
Compared with the prior art, the biggest difference between the benzene-free plastic ink diluent composition of the present invention is that it uses lower-priced hydrocarbon solvents, especially 90# gasoline or 93# gasoline or 97 #Gasoline, turpentine, and ethyl acetate are the main raw materials, replacing benzene or benzene derivatives, solving the technical problem of benzene poisoning caused by benzene and its derivatives, and achieving good dilution effect, high volatility and solubility effect.
The production method of the present invention is to measure each part of the diluent composition according to the amount and put it into a stainless steel or ceramic container, mix it evenly under normal temperature and pressure, and place it in a sealed seal. Add it directly to the ink and mix well before use.
The diluent composition of the present invention can be applied to printing plastics, and can also be used as a diluent for printing inks for books and newspapers.
