Abstract

The invention discloses an environment-friendly permanent bordeaux composite pigment for nitro ink and a preparation method thereof. The environment-friendly permanent bordeaux composite pigment for nitro ink is prepared from, by weight parts, 2-4 parts of permanent bordeaux 2BL, 15-25 parts of poly(oxy-1,2-ethanediyl), 11-20 parts of acetone, 5-11 parts of zinc oxide, 5-9 parts of paraffin oil, 3-6 parts of nano silica, 2-3 parts of butyl acetate, 1-3 parts of ammonium persulfate, 0.5-1 part of isophorone diamine and 0.5-1 part of benzoyl peroxide. The invention further provides a method for preparing the environment-friendly permanent bordeaux composite pigment for the nitro ink.

Description

technical field [0001] The invention belongs to the field of pigments, in particular to an environment-friendly permanent red composite pigment for nitro ink and a preparation method thereof. Background technique [0002] Ink is an important material for printing, by printing patterns and characters on substrates. The ink includes the main coloring components and auxiliary components, mainly composed of linking materials, pigments, fillers, additives and solvents. Inks are widely used in various printings such as books, periodicals, packaging, decoration, architectural decoration and electronic circuit boards. [0003] With the continuous development of the economy, the call for environmental protection is getting higher and higher. The printing industry has put forward new requirements for non-toxic and non-polluting offset printing inks. Environmentally friendly offset printing inks have attracted widespread attention from users and have begun to be used in packaging, new...
