Problems solved by technology

Due to the presence of hydrophilic groups in waterborne polyurethane, the coating formed by it has poor water resistance, heat resistance and viscoelasticity, especially the difference in water resistance, which directly affects the experience of printing products. Performance is further improved to perfect its performance
"Preparation and Characterization of Nano-Silica Modified Waterborne Polyurethane Dispersion" In the article, a silane coupling agent was used to hydrolyze and disperse in a polyoxypropylene glycol solution to prepare a nano-silica polyoxypropylene glycol dispersion, which participated in the synthesis of water-based polyurethane process, obtained nano-silica modified water-based polyurethane emulsion, the hydrophobicity and surface hardness of the polyurethane coating obtained by this method have been improved to a certain extent, but its tensile strength and elongation at break have decreased accordingly. The mechanical properties are poor, so it can be seen that obtaining an emulsion with excellent mechanical properties while improving the hydrophobicity of water-based polyurethane is the research focus with practical application value, and it is also the purpose of the present invention

Abstract

The invention discloses a flame-retardant fireproof modified waterborne polyurethane printing ink. The printing ink has the advantages that waterborne polyurethane is modified by hexafluorobutyl methacrylate and glycidyl methacrylate, and accordingly, obtained polyurethane emulsion has better water resistance; through addition of raw materials such as ammonium polyphosphate and porous calcium silicate, the printing ink has good flame retardance and fire resistance effect, and performance of conventional waterborne polyurethane printing ink is improved greatly; the printing ink has low viscosity and high strength and is safe and environment friendly, function persistence and stability are achieved, and application range is widened.

Description

technical field [0001] The invention relates to the technical field of water-based inks, in particular to a flame-retardant and refractory modified water-based polyurethane ink and a preparation method thereof. Background technique [0002] Water-based ink is composed of water-soluble resins, organic pigments, solvents and related additives. It has excellent environmental protection and can alleviate the current pollution problems in the packaging and printing industry. It has become the key development direction of the ink industry at present and in the future. [0003] Water-based polyurethane ink has the advantages of good color expression, good adhesion, oil resistance, etc., and has wide applicability to various substrate materials. Due to the presence of hydrophilic groups in waterborne polyurethane, the coating formed by it has poor water resistance, heat resistance and viscoelasticity, especially the difference in water resistance, which directly affects the experien...
