Diluting agent for silk-screen printing ink for plastic product

Abstract

The invention discloses a production formula of a diluting agent for silk-screen printing ink for a plastic product and a preparation method thereof. The diluting agent consists of methylene dichloride, dichloroethane, ethyl acetate, butyl acetate, ethyl methyl ketone, acetone, cyclohexanone, glycol ethylene ether, ethylene glycol monobutyl ether and butanol, wherein the total content of the components in the formula is 100 percent. An alkane solvent in the formula has strong dissolving action on a general plastic product. When the diluting agent is blended with ink and the blend is applied to the plastic product by silk-screening printing, the surface of the plastic product is slightly dissolved by the alkane solvent in the ink, and the ink permeates into the plastic product, so that dryink can be resistant to friction and alcohol wiping. The diluting agent for the silk-screen printing ink for the plastic product does not contain benzene or methanol organic solvent or turpentine oil, the ink is dried quickly, the product can be resistant to friction and alcohol wiping after silk screen printing. The diluting agent is widely used for diluting ink for silk-screen printing and transfer printing of plastic products.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a production formula and a production method of a diluent for screen printing ink of plastic products. Background technique [0002] At present, most of the thinners used in screen printing inks for plastic products on the market contain benzene solvents or methanol. These ink thinners containing benzene solvents or methanol not only have a strong smell and serious pollution, but also seriously endanger the health of operators. Long-term Exposure to such ink thinners can cause damage to the blood system of the human body, causing a decrease in white blood cells, thrombocytopenia, and vision loss. A typical representative of this kind of ink thinner is "aromatic ink thinner", the patent number is: 03114183.8, and the ink thinner contains benzene solvent and methanol. There is also a "benzene-free plastic ink thinner" patent number: 200410060757.6 on the market. This ink...

Problems solved by technology

There is also a "benzene-free plastic ink thinner" patent number: 200410060757.6 on the market. This ink thinner contains turpentine, and the drying speed of the ink is slow, so it cannot be adapted to industrialized mass production.

For this reason, some factories have increased the drying process, which not only increases energy consumption, but also increases production costs.

In addition, these ink thinners also have a disadvantage, that is, the products after silk screen printing are not resistant to rubbing and alcohol scrubbing
