Embodiment
[0021] Embodiment: A degradable film with waterproof and moisture-permeable function, the degradable film is obtained by drying the slurry emulsion, and the slurry emulsion is composed of the following components by weight:
[0022]
[0023]
[0024] The slurry emulsion forms the degradable film through the following processes, including:
[0025] Step 1, the slurry emulsion is coated on the surface of silicone oil release paper by a scraper,
[0026] Step 2: Carry out the first-stage drying under the condition of 80-100°C and low-speed air flow,
[0027] Step 3: Carry out the second-stage drying under the condition of 110-130°C and low-speed air flow,
[0028] Step 4: Carry out the third-stage drying under the condition of 150-180°C and low-speed air flow,
[0029] Step 5, peeling off the silicone oil release paper after cooling to obtain the degradable film.
[0030] The gap of the scraper is 0.005-0.03mm.
[0031] The cooling temperature in the above step five is ...
