Natural drying type offset lithographic paper bottom ink and preparation method thereof

Abstract

The invention proposes a natural drying type offset lithographic paper bottom ink and a preparation method thereof. The ink consists of the following components in percentage by weight: 92.5 to 95.5 percent of modified rosin resin oil, 1.0 to 1.5 percent of flaxseed oil, 0.1 to 2.0 percent of nano-calcium carbonate, 2.5 to 5.0 percent of cerate and 0.5 to 1.0 percent of drying agent. According tothe invention, since the ink is produced with modified rosin resin and vegetable oil as main materials, not only is the development policy of the national resource industries met, but also the application range of vegetable oil can be promoted and broadened, the consumption of petroleum resin (petroleum derivative) can be reduced, the ecological environment of import can also be correspondingly improved, and more importantly, under the premise that printing houses choose inferior paper for printing, the natural drying type offset lithographic paper bottom ink provided by the invention can still obtain a high printing effect.

Description

technical field [0001] The invention relates to a naturally drying lithographic offset paper base ink and a preparation method thereof. Background technique [0002] Energy saving and environmental protection is an element that has attracted much attention and advocated in China and even the world today. Therefore, high-efficiency, energy-saving and environment-friendly products are accepted by all walks of life. [0003] At present, the printing industry is limited by the price increase of raw materials, labor costs and other factors, and uses poor quality paper for printing. Due to paper powder falling off, seat color and other reasons, the printing waste rate remains high, and the number of shutdowns for cleaning machines increases. , forming more waste water. In view of this, the paper base oil was developed under these factors. [0004] At present, the printing industry's solution to the poor paper quality is to use a diluted ink to pre-coat the paper. However, due to ...
