Abstract

The invention discloses anti-rust printing ink. The anti-rust printing ink comprises 25-30 parts of waterborne polyurethane resin, 20-30 parts of waterborne acrylic resin, 4-6 parts of pigment, 3-4 parts of a thickening agent, 0.1-0.3 part of a dispersing agent, 5-6 parts of alcohol amine modified amorphous silica anti-rust filler, 30-40 parts of ethanol and 10-15 parts of deionized water. Alcoholamine modified amorphous silica is dispersed in the printing ink, and a compact passivation protective film can be formed on the surface of a metal product, so that the metal product is not easy to rust, and the packaging and printing effect of the metal product is guaranteed. In addition, the added alcohol amine modified amorphous silica anti-rust filler can be well fused with other components,and a synergistic effect is achieved, so that the stability, compactness and viscosity of the protective film are enhanced; and the anti-rust performance of the printing ink is enhanced, and the metalproduct is effectively prevented from rusting.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an antirust ink. Background technique [0002] Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink mainly includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. When the ink is printed on the metal product, in a humid environment, the metal product is prone to rust due to moisture, thereby causing the ink to fall off, thereby affecting the packaging of the metal product. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide an antirust ink, which has good antirust performance and can effectively prevent metal products from rusting, thereby ensuring the packaging and printing effect of metal products . [0004] Th...
