Anti-sun printing ink and preparation method thereof

Abstract

The invention discloses anti-sun printing ink. The anti-sun printing ink consists of the following raw materials in parts by weight: 2 to 3 parts of epoxypropane, 30 to 40 parts of tetrabutyl titanate, 14 to 20 parts of epoxy resin E51, 10 to 20 parts of chlorine vinegar resin, 50 to 60 parts of methyl methacrylate, 10 to 30 parts of butyl acrylate, 2 to 3 parts of an initiator, 1 to 2 parts of fatty acid diethanolamide, 1 to 2 parts of benzotriazole, 0.3 to 1 part of a catalyst and 3 to 4 parts of a silane coupling agent kh550. The dispersing compatibility of titanium sol in the chlorine vinegar resin and polyester is improved and the uniform stability strength of the finished product printing ink is improved; and the titanium sol has good photocatalytic effect, so the anti-sun property of the finished product can be effectively improved.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to an anti-sun ink and a preparation method thereof. Background technique [0002] Water-based ink is an ink with water as a solvent. The advantages of water as a solvent are: non-toxic, odorless, non-flammable, and greatly reduces VOC emissions, reducing environmental pollution, so it has developed rapidly; [0003] At present, most of the water-based inks are polyurethane inks, which not only have the characteristics of safety and environmental protection of water-based inks, but also have the unique advantages of polyurethane with excellent wear resistance, water resistance, chemical resistance and adjustable hardness. The application field of polyurethane in ink is more and more extensive; however, water-based polyurethane has the weakness of congenitally insufficient water resistance due to the hydrophilic group in its molecular structure, and the performance of water-based polyu...

Problems solved by technology

[0003] At present, most of the water-based inks are polyurethane inks, which not only have the characteristics of safety and environmental protection of water-based inks, but also have the unique advantages of polyurethane with excellent wear resistance, water resistance, chemical resistance and adjustable hardness. The application field of polyurethane in ink is more and more extensive; however, water-based polyurethane has the weakness of congenitally insufficient water resistance due to the hydrophilic group in its molecular structure, and the performance of water-based polyurethane cannot be compared with traditional solvent-based polyurethane. Therefore, , the purpose of the present invention is to provide a new polyester ink, to improve the bonding performance of the ink, etc.
