Problems solved by technology

At present, the ink still has the problem of volatile organic compound (VOC) emission, and the waste petroleum-based ink after printing is difficult to biodegrade and causes pollution.
These problems have had adverse effects on the environment during the production and use of inks, and do not meet the requirements of modern society for environmental protection.

example 1

[0013] A phenolic-free VOC-free ink, the ink color is ruby ​​red, the weight ratio of its components is: modified rosin ester resin 36%, linseed oil 34%, tung oil 3%, red pigment 16%, colloidal carbonic acid Calcium 4%, rapeseed oil methyl ester 4%, drier 0.5%, micronized wax 1%, antioxidant 1%, vanilla oil 0.5%.

example 2

[0015] A kind of phenol-formaldehyde-free VOC-free ink, its ink color is blue, and its weight ratio of each component is: modified rosin ester resin 32%, linseed oil 39%, tung oil 3%, blue pigment 14%, colloid Calcium carbonate 4%, rapeseed oil methyl ester 5%, drier 1%, micronized wax 1%, antioxidant 0.5%, vanilla oil 0.5%.

example 3

[0017] A kind of phenol-formaldehyde-free and VOC-free ink, the ink color is black, and the weight ratio of its components is: 30% modified rosin ester resin, 39% linoleum, 3% tung oil, 17% black pigment, colloidal calcium carbonate 4%, rapeseed oil methyl ester 4%, drier 0.5%, micronized wax 1.5%, antioxidant 0.5%, vanilla oil 0.5%.

[0018] The preparation methods of the above three embodiments are as follows: put the modified rosin ester resin into the stainless steel binder refining kettle or the stainless steel resin kettle, add the measured tung oil and linseed oil successively, after heating and melting, start stirring, and continue to heat up to 220 ~250℃ for a period of time, lower the temperature and add the measured rapeseed oil methyl ester to adjust the index to pass, then filter and transfer to the binder storage tank. Add pigment, colloidal calcium carbonate, micropowder wax, antioxidant, drier and vanilla oil to the modified rosin ester resin bonding material r...

Abstract

The invention relates to phenolic aldehyde and VOC free printing ink, which comprises the following components by weight: 30%-40% of modified rosin ester resin, 35%-44% of linoleic, 3%-5% of tung oil, 12%-18% of a pigment, 3%-4% of colloidal calcium carbonate, 3%-5% of rapeseed oil methyl ester, 0.5%-1% of a drier, 1%-2.5% of micronized wax, 0.5%-1% of an anti-oxidant, and 0.5%-1% of vanilla oil. The formula of the invention adopts modified rosin ester resin, linoleic and tung oil as main raw materials for producing printing ink, which can has the characteristics of bright and pure color, biodegradability, and excellent mechanical stability as well as good post-press finishing property, good deinking effects of printed matters, and low comprehensive printing cost, etc.

Description

technical field [0001] The invention relates to a coating, in particular to a hot-dip galvanized substrate anticorrosion coating with good chemical anticorrosion and excellent adhesion strength. Background technique [0002] At present, phenolic formaldehyde remains in the product during the manufacture and printing of inks. Phenolic formaldehyde contains a large amount of formaldehyde which is harmful to the human body. Due to its molecular structure, phenolic formaldehyde cannot be well linked with each other, and there are a large amount of powder. Just like chalk, a lot of dust comes off when everything is cut with a knife. So many manufacturers use a lot of glue to bond them together. At present, the ink still has the problem of volatile organic compound (VOC) emission, and the problem of pollution caused by the difficulty of biodegradation of waste petroleum-based ink after printing. These problems have had adverse effects on the environment during the production and...
