| titleOfInvention | Sericin-modified water-based polyurethane waterproof and moisture-permeable coating and preparation method thereof |
| abstract | The invention discloses a sericin-modified water-based polyurethane waterproof and moisture-permeable coating and a preparation method thereof, and relates to the technical field of textile waterproof and moisture-permeable coatings. In the method provided by the invention, sericin with a certain cross-linked structure is selected as a component of the water-based waterproof and moisture-permeable polyurethane, and in the preparation process, according to the structural characteristics of sericin, sericin is hydrolyzed with aminopropyl Triethoxysilane reacts to connect the amino group to the sericin structure, making it an effective chain extender for water-based polyurethane, so that sericin can be introduced into the water-based polyurethane structure, which greatly improves the moisture permeability and water resistance of the polyurethane fabric coating. Therefore, the technical problems of poor water resistance, poor mechanical strength and poor moisture permeability of the existing water-based polyurethane waterproof and moisture-permeable coatings are solved, and the technical effect of improving the water resistance, mechanical strength and moisture permeability of the water-based polyurethane waterproof and moisture-permeable coatings is achieved. |
