Embodiment A
[0047] Prepare the water-based foam layer, by 2.0mol% hardener hexamethylene diisocyanate and 0.2mol% polyethylene glycol PEG2000 (polyethylene glycol, PEG, M n2000) and 0.8mol% polypropylene glycol PPG2000 (polypropylene glycol, PPG, M n 2000) mixed with 0.4mol% 2,2-dimethylol propionic acid and 0.1mol% ethylenediamine (ethylenediamine) and 0.3mol% 1,4-butanediol to form the main agent, and without adding functional additives, the preparation into a prepolymer; then use a mechanical foaming machine to make a mechanical foam, and coat it on centrifugal paper to form a water-based foam layer; a polyurethane film is formed on the water-based foam layer, and the bottom of the water-based foam layer is used for Attached to wounds of the skin; several dots of glue are coated on the polyurethane membrane.
Embodiment B
[0049] Prepare the water-based foam layer, by 2.0mol% hardener hexamethylene diisocyanate and 0.3mol% polyethylene glycol PEG2000 (polyethylene glycol, PEG, M n 2000) and 0.7mol% polypropylene glycol PPG2000 (polypropylene glycol, PPG, M n 2000) with 0.4mol% of 2,2-dimethylol propionic acid and 0.1mol% of ethylenediamine and 0.3mol% of 1,4-butanediol to form the main agent, and without adding functional additives, made Prepolymer; then use mechanical foaming machine to make mechanical foam, and spread it on centrifugal paper to make water-based foam layer; polyurethane film is formed on the water-based foam layer, and the bottom of water-based foam layer is used for pasting Attaches to wounds in the skin; the polyurethane membrane is coated with dots of glue.
Embodiment C
[0051] Prepare the water-based foam layer, first by 2.0mol% hardener hexamethylene diisocyanate and 0.4mol% polyethylene glycol PEG2000 and 0.6mol% polypropylene glycol PPG2000 and 0.4mol% 2,2-dimethylol propane The acid is mixed with 0.1mol% ethylenediamine and 0.3mol% 1,4-butanediol to form the main agent, and no functional additives are added to make a prepolymer; then mechanical foaming machine is used to make mechanical foam Foam body, coated on centrifugal paper to form a water-based foam layer; a polyurethane film is formed on the water-based foam layer, and the bottom of the water-based foam layer is used to attach to the wound of the skin; the polyurethane film is coated with a number of dots glue.
