Step 4: dry method veneer:
Being coated with by the dry method slurry prepared in step 3 scrapes in forming dry method veneer with in the release liners of flower pattern, then by adhesive be adhered on dry method veneer under the condition of 90 ~ 110 DEG C in temperature by the wet method bass in step 2, be separated through super-dry heel release liners;
Step 5: rub line:
Product after being separated by 20-50m, puts into water boarding machine and carries out washing 10 ~ 30 minutes, and take out and dewater and dry, bake out temperature controls at 90 ~ 120 DEG C.
As a further improvement on the present invention, dimethyl formamide and mill base high-speed stirred 90 minutes in described step a.
As a further improvement on the present invention, the mixed liquor of 240 order nylon wires to dimethyl formamide and mill base is used to filter in described step a;
B. by 100 ~ 120kg dimethyl formamide and 20 ~ 30kg wood powder mix and blend 30 minutes, then fully swelling 35 minutes, then add the mixture filtered in step a and stir stand-by;
C. 100kg polyurethane wet hydrolysis resin is joined in the mixture that step b formed, stir 40 minutes, deaeration 45 minutes.
As a further improvement on the present invention, step 3: dry mixed is prepared burden:
By high-speed stirred 15 minutes after the mixing of 100kg polyurethane dry method hydrolysis resin, 10 ~ 15kg dimethyl formamide, 10 ~ 15kg butanone, 15 ~ 20kg toluene, 0.5 ~ 1.0kg auxiliary agent and 3 ~ 5kg toner to stirring.
The invention has the beneficial effects as follows: the present invention, by use polyurethane wet hydrolysis resin and polyurethane dry method hydrolysis resin to reach effect that artificial leather itself has hydrolysis, cold-resistant, folding, effectively extends its service life.
