Embodiment 1
[0069] Such as figure 1 As shown, the high water pressure and high moisture permeability coating fabric of the present invention includes a load-bearing layer 4, a waterproof layer 3 coated on the load-bearing layer 4, and a microporous layer 2 coated on the waterproof layer 3, which is characterized in that : the coated fabric also includes a protective layer 1 coated on the microporous layer 2, and the protective layer 1 is a wear-resistant coating with a microporous structure.
[0070] The slurry of the waterproof layer 3 is: 83.3% of two-component polyether polyurethane, 12.5% of solvent, 2.5% of curing agent, and 1.7% of accelerator. The coating amount of the waterproof layer 3 is 4g / m in terms of solid content 2 .
[0071] Microporous layer 2 slurry contains 52.3% of aromatic polyether type polyurethane, butanone / toluene (12 / 24) 18.7%, trimer type polyisocyanate curing agent / polyfunctional group aziridine curing agent (5 parts by weight) / 1) 1.6%, defoamer / leveling...
Embodiment 2
[0075] as attached image 3 As shown, the high water pressure and high moisture permeability coating fabric of the present invention is prepared by the following process:
[0076] 1. Use a water-repellent agent to treat pongee with water-repellent treatment;
[0077] 2. Carry out calendering treatment on the base fabric after water-repellent treatment;
[0078] 3. Prepare the waterproof layer 3 slurry, and apply the waterproof layer 3 slurry on the base fabric to form the waterproof layer 3;
[0079] 4. Drying of waterproof layer 3;
[0080] The drying of the waterproof layer 3 is carried out in three temperature zones, the temperature ranges of each temperature zone are 90°C, 120°C, and 150°C respectively, and the drying time of each temperature zone is 0.8 minutes.
[0081] 5. Coating the microporous waterproof and moisture-permeable slurry on the waterproof layer 3 to form the microporous layer 2;
[0082] a. The preparation of the microporous layer 2 slurry: the batchi...
Embodiment 3
[0092] Compared with Example 1, the differences are:
[0093] The base fabric is nylon spinning;
[0094] The content of the two-component polyether polyurethane in the slurry of the waterproof layer 3 is 80%; the coating amount of the waterproof layer 3 is 3g / m in terms of solid content 2 .
[0095] The microporous layer 2 slurry contains 45% of aromatic polyether polyurethane and 12% of acetone / toluene (12 / 24) by weight, and the coating amount of microporous layer 2 is calculated by solid content: 20g / m 2 .
[0096] The slurry of the protective layer 1 is: polyurethane 70%, MCC microporous agent 2%, and the coating amount of the protective layer 1 is 3g / m in terms of solid content 2 .
