Abstract

The invention discloses an environment-friendly printing ink, which comprises the following raw materials by weight: 50-100 parts of natural pigment, 10-50 parts of linseed oil, 20-60 parts of water-soluble modified abietate resin, 30-80 parts of filler, 25-55 parts of an additive and 100-200 parts of water. The natural pigment is divided into red, yellow and blue colors, the red, yellow and blueraw materials are safflower, sophora flower and bluegrass respectively, and the preparation method comprises the following steps: raw material selection and cleaning, raw material cooking, raw material distillation, powder grinding, raw material mixing and ink packaging. The natural pigment is prepared through natural plant processing, compared with an existing pigment for ink, the pigment for inkis brighter in color, environmentally friendly and free of pollution, the problem that the existing pigment for printing ink is not bright in color or contains toxic substances is solved, and the printing ink has the anti-allergic characteristic and can be applied to printing of clothes.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an environmentally friendly printing ink. Background technique [0002] Existing inks are composed of pigments, binders, fillers and additional materials. Pigments play a role in color development in inks, and it has a direct impact on some characteristics of inks. Existing ink pigments are divided into organic pigments and inorganic pigments. pigment; [0003] Inorganic pigments are oxides of non-ferrous metals, or some metal insoluble metal salts. Inorganic pigments are divided into natural inorganic pigments and artificial inorganic pigments. Natural inorganic pigments are mineral pigments; [0004] Organic pigments are colored organic compounds, which are also divided into two categories: natural and synthetic. Now, synthetic organic pigments are commonly used. There are many varieties of organic pigments, relatively complete colors, and better performance than inorganic pigment...
