Embodiment approach 1

[0020] According to the molar ratio of rosin: maleic anhydride: TDI: pentaerythritol = 18:9.5:2.9:3.3, first heat and melt the rosin, then heat the maleic anhydride at 175-180°C for 0.9 hours, add TDI (toluene diisocyanate) for 1 hour, Add pentaerythritol and raise the temperature to 230°C for 1.8 hours. Then water, ammoniacal liquor and the water-soluble resin of making are dissolved into 38% solid content resin liquid; Get the weight percent of component again and be water-based resin liquid 69%, pigment 8%, defoamer 1%, micropowder wax 1.6% % to 2.4%, plasticizer 1.2%, erucamide 1.2%, water 18% to prepare water-based woven bag ink.

Embodiment approach 2

[0022] According to the molar ratio of rosin: maleic anhydride: TDI: pentaerythritol = 20: 9.5: 3.1: 3.2, first heat and melt the rosin, then heat the maleic anhydride at 185-190°C for 1 hour, add TDI (toluene diisocyanate) for 1 hour, Add pentaerythritol and raise the temperature to 240°C for 2 hours. Then water, ammoniacal liquor and the water-soluble resin of making are dissolved into 39% solid content resin liquid; Get the percentage by weight of component again and be water-based resin liquid 70%, pigment 9%, defoamer 1.1%, micropowder wax 2 %, plasticizer 1.2%, erucamide 1.2%, water 15.5% to prepare water-based woven bag ink.

Embodiment approach 3

[0024] According to the molar ratio of rosin: maleic anhydride: TDI: pentaerythritol = 20:10:3:3, first heat and melt the rosin, then heat the maleic anhydride at 180-185°C for 1 hour, add TDI (toluene diisocyanate) for 1 hour, Add pentaerythritol and raise the temperature to 240°C for 2 hours. Then water, ammoniacal liquor and the water-soluble resin of making are dissolved into 35% solid content resin liquid; The percentage by weight of getting component is water-based resin liquid 75%, pigment 10%, defoamer 1%, micropowder wax 2 %, 1% plasticizer, 1% erucamide, and 10% water to prepare water-based woven bag ink.

Abstract

The invention discloses an aqueous braided bag ink which comprises the components with the weight percentage: 68-76% of water-dilutable resin liquid, 7-11% of pigment, 0.8-1.2% of defoaming agent, 1.6-2.4% of superfine powder wax, 0.8-1.2% of plasticizer, 0.8-1.2% of erucyl amide and 7-21% of water. The aqueous braided bag ink can reduce the emission of organic volatile matter towards atmosphere, thus preventing atmospheric pollution, improving the environment of print operation and greatly reducing the hidden trouble of fire hazard. By adopting the invention, some toxic substance in the ink can be removed and prevented from harming human body and polluting the packed merchandise, thus improving the overall environmental quality. Furthermore, the aqueous braided bag ink has good holding fastness and scratch resistant performance as well as high glossiness.

Description

【Technical field】 [0001] The invention relates to a printing ink, in particular to a water-based woven bag ink and a preparation method thereof. 【Background technique】 [0002] Existing woven bag printing ink is to be main raw material with polypropylene (PP), polyethylene (PE) resin, through extruding, being stretched into flat wire, then through manufacturing, bag-making and form. In today's diversified market, woven bags have been constantly innovating, especially in the packaging of rice and vegetables, all kinds of colorful, novel and unique, OPP color film packaging bags, aluminized film packaging bags, laser film packaging bags, pearlescent packaging bags, etc. Packaging bags such as film packaging bags are rushing to the market. Woven bags are also more widely used in the packaging of building materials, cement, and resin chemicals. Traditional woven bag inks are generally printed with oil-based inks and alcohol-soluble inks. Because the formula contains a large am...
