Embodiment 1

[0010] Embodiment 1: the present invention adopts following proportioning: benzidine yellow G 15%, calcium carbonate 9%, soybean oil 22%, bleached linseed oil 8%, high boiling point kerosene 11.3%, solvent naphtha 6%, rosin modified phenolic resin 19% %, petroleum resin 9%, antioxidant 0.5%, liquid aluminum AO-3 0.2%. The use of calcium carbonate in this formula can reduce the cost, but requires good transparency of calcium carbonate.

Embodiment 2

[0011] Embodiment 2: the present invention adopts following proportioning: benzidine yellow G 15%, organic bentonite 0.5%, calcium carbonate 7%, soybean oil 22%, bleached linseed oil 8%, high boiling point kerosene 12.8%, solvent naphtha 6%, rosin Modified phenolic resin 19%, petroleum resin 9%, antioxidant 0.5%, liquid aluminum AO-3 0.2%. Reducing calcium carbonate and increasing organic bentonite in the formula can reduce the solid content in the ink and make the ink leveling better, which is suitable for high-speed printing.

Embodiment 3

[0012] Embodiment 3: the present invention adopts following proportioning: Lisol carmine 18%, calcium carbonate 7%, soybean oil 22%, bleached sesame oil 8%, high boiling point kerosene 11.3, solvent naphtha 5%, rosin modified phenolic resin 19% , petroleum resin 9%, antioxidant 0.5%, liquid aluminum AO-3 0.2%. The content of rosin-modified phenolic resin in this formula is slightly lower, which can reduce the cost, and is suitable for printing that does not require high gloss.

Abstract

The invention relates to a soybean oil type offset printing color ink which aims at realizing safety, environmental protection and good coloring property. The oil ink comprises the following components by weight percent: 10-25% of organic pigment, 5-10% of extender pigment, 20-30% of soybean oil, 5-15% of bleaching sesame oil, 10-20% of mineral oil, 25-35% of resin, 0.5-1% of antioxidant and 0.1-0.5% of gelatinizing agent; the sum of weights of all the components is 100%, wherein the mineral oil is any one of high-boiling point kerosene and solvent oil or the mixture of the two by any proportion; the resin is the mixture of rosin modified phenolic resin and petroleum resin, wherein the rosin modified phenolic resin accounts for 16-30% of the total weight percent of the oil ink, and the petroleum resin accounts for 5-15% of the total weight percent of the oil ink; the antioxidant is 2,6-di-tert-butyl-4-methylphenol; and the gelatinizing agent is liquid aluminum AO-3. The oil ink adoptsthe production technology of the ordinary offset printing oil ink for production.

Description

technical field [0001] The invention relates to a soybean oil type offset printing color ink used for lithographic printing. Background technique [0002] For the inks currently used in the lithographic printing industry, most of them are made of resin and petroleum-based solvents as binders, and then mixed with organic pigments, extender pigments, additives, etc., and petroleum-based mineral oils contain more polycyclic aromatic hydrocarbons Such substances, which contain carcinogenic ingredients, such as 3,4-benzopyrene, 3-nitrobenzophenone, etc., have a large amount of residues on printed materials such as books, newspapers, and albums, and last for a long time. Hazardous to both children and adults. Can not meet the requirements of human safety and environmental protection. Human body safety has two meanings: one is to protect the health and safety of operators who produce and use ink. On the other hand, it is the protection of the health and safety of people who use ...
