Background technology
[0002] present; The plastics ink for screen printing that uses on the market contains benzene kind solvent or methyl alcohol with the thinner great majority; These contain the printing ink reducer of benzene kind solvent or methyl alcohol, and not only smell is big, seriously polluted, and the serious harm operator's is healthy, and contacting this type printing ink reducer for a long time can damage the blood system of human body; Cause leukopenia, situation such as thrombopenia and visual deterioration.Typical case's representative as " the perfumed ink thinner " of this type printing ink reducer, the patent No. is: 03114183.8, this printing ink reducer contains benzene kind solvent and methyl alcohol.A kind of in addition on the market " benzene-free plastic printing ink reducer " patent No. is: 200410060757.6, contain turps in this printing ink reducer, and ink setting speed is slow, can not adapt to industrialized mass production.For this reason, some factories have increased baking operation, have so both increased energy consumption, have increased production cost again.In addition, these printing ink reducers also have a shortcoming, are exactly not wear-resisting wiping of product and the smart scouring of alcoholic intolerance behind the silk-screen.
Summary of the invention
The purpose of this invention is to provide a kind of not containing benezene and methyl alcohol kind solvent, do not contain turps, rate of drying fast and can rub and the plastics ink for screen printing of alcohol resistance scrubbing with production formula of thinner and preparation method thereof.
In order to achieve the above object; A kind of plastics ink for screen printing of the present invention is made up of methylene dichloride, ethylene dichloride, ETHYLE ACETATE, butylacetate, methylethylketone, acetone, pimelinketone, ethylene glycol ethyl ether, butyl glycol ether and butanols with thinner; The weight percent that its prescription is formed is: methylene dichloride 3%~10%, ethylene dichloride 3%~10%, ETHYLE ACETATE 5%~10%, butylacetate 5%~15%, methylethylketone 5%~10%, acetone 3%~6%, pimelinketone 20%~40%, ethylene glycol ethyl ether 5%~10%, butyl glycol ether 5%~15%, butanols 1%~3%, each component concentration sum is 100% in the prescription.Because the alkanes solvent in the prescription has stronger solvency action to the general-purpose plastics goods; When doubling prints on the plastics after thinner and the printing ink mediation; Alkanes solvent in the printing ink dissolves surface of plastic products slightly; Ink penetration so just can wear-resisting wiping and alcohol resistance scrubbing behind the ink setting to the inside of plastics.
Embodiment of the present invention is:
Methylene dichloride, ethylene dichloride, ETHYLE ACETATE, butylacetate, methylethylketone, acetone, pimelinketone, ethylene glycol ethyl ether, butyl glycol ether and butanols are added in the stainless steel whisking appliance successively; The stirring arm of turn on agitator (used motor is a fire proof motor); The control stirring velocity is 60 γ/min~80 γ/min; Churning time is 5~15min; After stirring end the mixed solvent in the reaction kettle is emitted and poured in vinyon bottle or the galvanized sheet iron bucket, so promptly make the plastics ink for screen printing and use thinner.
The invention has the beneficial effects as follows, this plastics ink for screen printing with thinner not containing benezene and methyl alcohol kind solvent, do not contain turps, ink setting speed is fast, the goods behind the silk-screen can rub resistance and alcohol resistance scrubbing.
Embodiment 1
Methylene dichloride 5%, ethylene dichloride 5%, ETHYLE ACETATE 10%, butylacetate 5%, methylethylketone 10%, acetone 4%, pimelinketone 40%, ethylene glycol ethyl ether 10%, butyl glycol ether 10%, butanols 1% are added (used motor is a fire proof motor) in the stainless steel whisking appliance successively; The stirring arm of turn on agitator; The control stirring velocity is 80 γ/min; Churning time is 10min; After stirring end the mixed solvent in the whisking appliance is emitted and poured in the vinyon bottle, so promptly make the plastics ink for screen printing and use thinner.
Embodiment 2
Methylene dichloride 10%, ethylene dichloride 5%, ETHYLE ACETATE 10%, butylacetate 8%, methylethylketone 8%, acetone 5%, pimelinketone 35%, ethylene glycol ethyl ether 10%, butyl glycol ether 7%, butanols 2% are added (used motor is a fire proof motor) in the stainless steel whisking appliance successively; The stirring arm of turn on agitator; The control stirring velocity is 60 γ/min; Churning time is 15min; After stirring end the mixed solvent in the whisking appliance is emitted and poured in the galvanized sheet iron bucket, so promptly make the plastics ink for screen printing and use thinner.
