B: polyurethane middle level resin 80～100kg, antimildew and antibacterial agent 0.2～0.8kg, dimethyl formamide 20～40kg, butanone 40～60kg, auxiliary agent 0.5～2kg and toner 5～8kg high-speed stirred is even, mixing time 15～20 minutes, make middle material, the filtration sealing is stand-by;
C: high-speed stirred after polyurethane binder resin 80～100kg, dimethyl formamide 20～40kg, butanone 30～60kg, crosslinking agent 8～15kg and the toner 5～8kg mixing is even, mixing time 10～15 minutes, make the adhesive with good degree of cross linking, the filtration sealing is stand-by;
Step 2: choose release liners and base fabric;
Step 3: dry method veneer:
The dry method fabric for preparing evenly is coated on the release liners of choosing dries, baking temperature is 100～140 ℃, make the surface layer dry film with antimildew and antibacterial effect, on the surface layer dry film, evenly apply again middle material, then oven dry, bake out temperature is 120～140 ℃, make the middle level dry film, then on the dry film of middle level, evenly apply the adhesive with good degree of cross linking, stick the base fabric of choosing at adhesive surface again, dry under 120～145 ℃ of conditions through baking oven, then cooling forming finally separates namely getting leather for medical bed with release liners;
Step 4: check, packing:
Gained finished product in the step 3 checked according to test stone and the packing case of packing in.
As a further improvement on the present invention, speed of production is in the described step 3: 8～12 m/mins.
As a further improvement on the present invention, in the described step 2 release liners with the flower type.
As a further improvement on the present invention, base fabric is that height is torn base fabric in the described step 2.
As a further improvement on the present invention, mixture all mixes in the reactor that can take out negative pressure in the described step 1.
The invention has the beneficial effects as follows: technique of the present invention is simple, is convenient to production operation, and the synthetic leather that uses process of the present invention to produce has advantages of that antimildew and antibacterial, high abrasion, high scratch resistance, height are torn, height is peeled off.
