Abstract

The invention discloses a cationic self-matting resin, and a preparation method and application thereof. The cationic self-matting resin comprises isocyanate, a diamine cationic hydrophilic chain extender, macropolyol, monohydric alcohol and/or dihydric alcohol with the main chain and/or the side chain containing a polyoxyethylene chain, a small molecular diamine chain extender, a catalyst, a solvent and a neutralizing agent. The preparation method has the advantages of simple process, convenience in operation, safety and non-toxicity, and the obtained cationic self-matting resin has the advantages of small particle size fluctuation, good emulsion stability and resistance, good adhesion to anionic leather, glass and other substrates, and bringing of soft and smooth hand feeling and naturalrich appearance for leather, and can be widely applied to the fields of leather finishing, wood plastics, paper printing, printing and dying inks, printing coatings, packaging coatings and matt nailpolish.

Description

technical field [0001] The invention belongs to the technical field of cationic self-extinction resin preparation, and relates to a cationic self-extinction resin and its preparation method and application. Background technique [0002] Water-based polyurethane has the characteristics of non-toxicity, flexibility, environmental protection, and easy modification due to its use of water as the medium. Under the premise of today's increasingly high environmental protection requirements, water-based polyurethane is widely used in textile coatings, wood, architectural coatings, metals, adhesives and leather. With the development of society and the continuous improvement of aesthetics, the pursuit of self-extinction or matte is becoming more and more vigorous. At present, there are mainly two methods to achieve the effect of extinction: external addition method and self-extinction. Among them, the external addition method mainly achieves the matting effect by adding matting powd...
