A kind of benzene-free environmental protection woven bag drool composite special ink and preparation method thereof

Abstract

The invention discloses a special printing ink for casting and compounding a benzene-free environment-friendly woven bag. White ink is prepared from the following raw materials in parts by weight: 12 to 18 parts of ethyl acetate, 25 to 32 parts of 25-percent ester soluble chlorinated EVA (Ethylene Vinyl Acetate) solution, 4 to 8 parts of 50-percent ester soluble DM solution, 18 to 23 parts of rutile titanium dioxide, 12 to 15 parts of fillers, 15 to 20 parts of 20-percent ester soluble modified chlorinated polypropylene solution and 1 to 2 parts of environment-friendly modified PP (Polypropylene) extruded composite enhancing agent. Colored ink is prepared from the following raw materials in parts by weight: 25 to 32 parts of ethyl acetate, 23 to 30 parts of 25-percent ester soluble chlorinated EVA solution, 3 to 8 parts of 50-percent ester soluble DM solution, 2 to 6 parts of 50-percent ester soluble rosin solution, 5 to 7 parts of organic pigment, 5 to 15 parts of fillers and 17 to 22 parts of 20-percent ester soluble modified chlorinated polypropylene solution. The special printing ink is the white or colored printing ink prepared by taking ethyl acetate as a main solvent and taking ester soluble modified chlorinated polypropylene and the like as main connection materials through pre-dispersion, sand milling and adjustment, and has the characteristics of good flowing performance, excellent printing shallow screen transferring effect, high printing adaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection inks, and in particular relates to a benzene-free environmental protection woven bag salivation compound special ink and a preparation method thereof. Background technique [0002] Judging from the current market survey on the use of inks in the color printing industry, in the flexible packaging fields such as food, pharmaceuticals, daily chemicals, cigarette packs, and cosmetics, the use of inks is gradually transitioning from benzene and ketone-containing to benzene-free and ketone-free environmentally friendly inks. The quality of flexible packaging ink is also continuously improved, which can completely replace the performance of traditional ink. However, in the printing of composite plastic woven bags used for packaging of chemical fertilizers and rice, most of them still use traditional inks containing benzoketones, which have the following defects: [0003] (1) The product...

AI Technical Summary

Problems solved by technology

[0003] (1) The production and use of inks are mainly based on benzene and ketone solvents, which have a great impact on the human body and the environment, especially for the treatment of VOCS.

[0004] (2) The production and use of ink are mainly based on benzene and ketone solvents, and the overall cost is relatively high

[0005] (3) Due to the traditional ink material selection and formula factors, the salivation compound peeling force of the printing film and the woven bag is often low, which cannot meet the requirements of the GB / T8947-1998 "Composite Plastic Woven Bag". High lamination temperature, the tensile load of the woven bag will not meet the standard, which will eventually cause quality problems such as bag breakage or lamination of the lamination film after the contents are installed
