Background technology
At present, the diluting agent for silk-screen printing ink for plastic product great majority that use on market contain benzene kind solvent or methyl alcohol, these contain the printing ink reducer of benzene kind solvent or methyl alcohol, and not only smell is large, seriously polluted, and the serious harm operator's is healthy, this class printing ink reducer of Long Term Contact can damage the blood system of human body, cause leukopenia, the situations such as thrombopenia and visual deterioration.The Typical Representative of this class printing ink reducer is as " aromatic printing ink diluting agent ", and the patent No. is: 03114183.8, and this printing ink reducer contains benzene kind solvent and methyl alcohol.On market in addition a kind of " diluent of benzeneless plastic printing ink " patent No. be: 200410060757.6, contain turps in this printing ink reducer, 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 again production cost.In addition, these printing ink reducers also have a shortcoming, are exactly the not wear-resisting wiping of product and the scouring of alcoholic intolerance essence after 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 is fast, can wear-resisting wiping and the production formula of the diluting agent for silk-screen printing ink for plastic product of alcohol resistance scrubbing and preparation method thereof.
in order to achieve the above object, a kind of diluting agent for silk-screen printing ink for plastic product of the present invention is by methylene dichloride, ethylene dichloride, ethyl acetate, butylacetate, methylethylketone, acetone, pimelinketone, ethylene glycol ethyl ether, butyl glycol ether and butanols form, the weight percent that its formula forms is: methylene dichloride 3%~10%, ethylene dichloride 3%~10%, ethyl 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%, in formula, each component concentration sum is 100%.Because the alkanes solvent in formula has stronger solvency action to the general-purpose plastics goods, when after thinner and printing ink mediation, doubling prints on plastics, alkanes solvent in printing ink dissolves surface of plastic products slightly, ink penetration so just can wear-resisting wiping and alcohol resistance scrubbing after ink setting to the inside of plastics.
The specific embodiment of the present invention is:
Methylene dichloride, ethylene dichloride, ethyl acetate, butylacetate, methylethylketone, acetone, pimelinketone, ethylene glycol ethyl ether, butyl glycol ether and butanols are added in the stainless steel agitator successively, the stirring rake of turn on agitator (motor used is 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 reactor is emitted and poured in vinyon bottle or galvanized sheet iron bucket, so namely make plastic prod ink for screen printing thinner.
The invention has the beneficial effects as follows, this diluting agent for silk-screen printing ink for plastic product not containing benezene and methyl alcohol kind solvent, do not contain turps, ink setting speed is fast, the goods after silk-screen can wear-resisting wiping and alcohol resistance scrubbing.
Embodiment 1
Methylene dichloride 5%, ethylene dichloride 5%, ethyl acetate 10%, butylacetate 5%, methylethylketone 10%, acetone 4%, pimelinketone 40%, ethylene glycol ethyl ether 10%, butyl glycol ether 10%, butanols 1% are added in the stainless steel agitator successively, the stirring rake of turn on agitator (motor used is fire proof motor), the control stirring velocity is 80 γ/min, churning time is 10min, after stirring end, the mixed solvent in agitator is emitted and poured in the vinyon bottle, so namely make diluting agent for silk-screen printing ink for plastic product.
Embodiment 2
Methylene dichloride 10%, ethylene dichloride 5%, ethyl acetate 10%, butylacetate 8%, methylethylketone 8%, acetone 5%, pimelinketone 35%, ethylene glycol ethyl ether 10%, butyl glycol ether 7%, butanols 2% are added in the stainless steel agitator successively, the stirring rake of turn on agitator (motor used is fire proof motor), the control stirring velocity is 60 γ/min, churning time is 15min, after stirring end, the mixed solvent in agitator is emitted and poured in the galvanized sheet iron bucket, so namely make diluting agent for silk-screen printing ink for plastic product.
