The resin comprises the following components in percentage by mass: 12% to 15% of poly adipic acid-1, 4-butanediol ester glycol, 7% to 9% of diphenyl-methane-diisocyanate MDI, 1% to 2% of a mixing chain extendor, 0.5% to 0.6% of a terminating agent, 0.3% to 0.5% of a high-speed penetrating agent OT, 0.02% to 0.04% of a catalyst, 0.3% to 0.5% of filling material, 0.1% to 0.2% of a stabilizer UV-329, and the balance of an organic solvent. As the polyurethane resin and the preparation method thereof adopt the mixing chain extendor, and measures such as adding an organic solvent DMF and the filling material CMC twice, the prepared polyurethane resin has excellent waterproof moisture permeable properties ( water-fast pressure larger than and equal to 3000 mm H2O, and moisture permeable property larger than and equal to 5000 g / m 2.24 Hr), and is good in rebound resilience and peel strength, high in water-fast pressure, and soft, plump, and fine and smooth in handfeel.

The invention discloses a high-performance variable flannelette. The high-performance variable flannelette comprises a flannelette body, the flannelette body comprises a bacteriostatic layer, the surface of the bacteriostatic layer is fixedly connected with a thermal insulation layer, the surface of the thermal insulation layer is fixedly connected with a waterproof and breathable layer, the surface of the waterproof and breathable layer is fixedly connected with a first flame-retardant layer, and the surface of the first flame-retardant layer is fixedly connected with an electrostatic elimination layer. Through arrangement of the bacteriostatic layer, the thermal insulation layer, the waterproof and breathable layer, the first flame-retardant layer, the electrostatic elimination layer, araised flannelette layer, the second flame-retardant layer and a surface layer for cooperative use, the flame retardancy and electrostatic elimination property of the flannelette body can be improved,fire caused by sparks due to large static electricity generated by the flannelette body can be avoided, the phenomenon that conventional flannelettes burn in fire due to poor flame retardancy can also be effectively avoided, and the problem of poor flame retardancy of existing variable flannelettes is solved. The high-performance variable flannelette has the advantages of being high in flame retardancy and worthy of popularization.
