Description
Technical Field
The invention belongs to the technical field of high-performance waterborne resin, and particularly relates to waterborne polyurethane resin; in particular to a method for preparing the waterborne polyurethane resin.
Background
A certain toxic solvent is used in the synthesis process of the high polymer material, but the cyclic utilization of the high polymer material can be ensured, and the residual rate of the high polymer material in a product can be reduced. The synthesis of aqueous polyurethane resins is a typical example in this respect. The water-based polyurethane resin is a uniform emulsion formed by dispersing polyurethane in water, has the advantages of non-inflammability, small smell, no environmental pollution, energy conservation, convenient operation and processing and the like, and is widely used as an adhesive and a coating. Compared with the solvent type polyurethane adhesive, the waterborne polyurethane has the following characteristics:
(1) most aqueous polyurethane resins do not contain reactive NCO groups, and thus the resins are cured mainly by the cohesion and adhesion of polar groups within the molecule. Carboxyl, hydroxyl and the like in the waterborne polyurethane can participate in reaction under proper conditions to cause the adhesive to generate crosslinking.
(2) Viscosity is an important parameter for the performance of the adhesive. The viscosity of the aqueous polyurethane resin is generally adjusted by a water-soluble thickener and water.
(3) Because the volatility of water is lower than that of an organic solvent, the water-based polyurethane adhesive is slower to dry, and the water resistance of the material is poorer.
(4) The aqueous polyurethane resin may be mixed with a variety of aqueous resins to improve performance or reduce cost.
(5) The waterborne polyurethane resin has small smell, convenient operation and easy cleaning of residual glue.
Due to the excellent physical and mechanical properties and biocompatibility, the material has wide application in the fields of leather, adhesives, coatings, medical instruments and the like. The development of a high-performance aqueous polyurethane resin material is receiving more and more attention from research and development personnel.
