Abstract

The invention discloses degradable offset printing ink, and relates to the technical field of degradable ink. The offset printing ink provided by the invention is prepared from the following raw materials in parts by weight: 40 to 60 parts of PU (Polyurethane)-6011 waterborne polyurethane, 15 to 30 parts of polylactic acid, 10 to 20 parts of colorant, 8 to 15 parts of linseed oil, 6 to 12 parts ofrosin, 3 to 6 parts of PPC, 1 to 4 parts of 4010 wetting dispersant, 2 to 6 parts of RQT-P-1 plasticizer, 8 to 16 parts of additive and 25 to 38 parts of organic solvent. The degradable offset printing ink provided by the invention is reasonable in componential proportion, has the advantages of being quick in drying rate, good in impact strength and high in degradation rate, and can be used for the printing of a book, a bag, a newspaper, a sheet material and the like.

Description

Technical field: [0001] The invention relates to the technical field of degradable inks, in particular to a degradable offset printing ink. Background technique: [0002] With the progress of the printing industry, offset printing is favored by domestic and foreign printing manufacturers for its unique advantages, such as fast and convenient plate making, low cost, high printing quality, wide range of paper use, and large printing quantity shrinkability. extensive development. [0003] In the prior art, offset printing ink is mainly composed of colored pigments (dyes, etc.), binders, fillers and additives. When preparing, it is mixed and stirred according to the requirements of printing according to a certain proportion, and is rolled and rolled. production. However, additives such as organic solvents and auxiliaries contained in offset printing inks have certain environmental hazards, and their degradability is poor after being buried in soil. At present, the development...
