Description
Technical field
The present invention relates to water color ink technical field, particularly relate to a kind of water-resistant type water-based polyurethane ink containing modified alta-mud and preparation method thereof.
Background technology
Water color ink is to be made up of water-soluble resin, organic pigment, solvent and related auxiliaries, and it has the excellent feature of environmental protection, can alleviate current packaging and there is pollution problem with printing industry, become current and ink industry from now on prior development direction.
Water-based polyurethane ink has the advantages such as color representation power good, adhesive force is good, oil resistant, and various stock materials are had wide applicability.Owing to aqueous polyurethane existing hydrophilic group, its water-resistant coating formed, thermostability and viscoelasticity be not good enough, especially the difference of resistance to water, directly affects the experience of print product, it is therefore desirable to the performance of aqueous polyurethane is made further improvements, to improve its performance." preparation of nano silicon dioxide modifying water polyurethane dispersing liquid and sign " literary composition utilizes silane coupler to hydrolyze dispersion in polyoxypropyleneglycol solution and prepares nano silicon polyoxypropyleneglycol dispersion, participate in aqueous polyurethane building-up process, obtain nano-silicon dioxide modified aqueous polyurethane emulsion, its hydrophobicity of the polyurethane coating that this method obtains and case hardness have obtained certain improvement, but its hot strength and elongation at break decrease, comprehensive mechanical property is not good enough, as can be seen here, possess the emulsion of excellent mechanical property and be only improving hydrophobic acquisition of aqueous polyurethane simultaneously there is the research emphasis of actual application value, also it is purpose of the present invention place.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of water-resistant type water-based polyurethane ink containing modified alta-mud and preparation method thereof.
The present invention is achieved by the following technical solutions:
