Step one: wet-mixing is prepared burden:
A. by 5 ~ 10kg dimethyl formamide and 0.5 ~ 2kg mill base high-speed stirred 80 ~ 100 minutes, then filter stand-by;
B. by 100 ~ 120kg dimethyl formamide and 20 ~ 30kg wood powder mix and blend 20 ~ 30 minutes, then fully swelling 30 ~ 40 minutes, then add the mixture filtered in step a and stir stand-by;
C. 100kg polyurethane wet resin is joined in the mixture that step b formed, stir 30 ~ 40 minutes, deaeration 40 ~ 50 minutes;
Step 2: wet method bass is produced:
Being coated with by the slurry that in step one, deaeration has been formed scrapes on the light face through compiling suede nap (another side of this suede nap is hair side), immersing mass percentage concentration is again solidify in the dimethylformamide in water of 18 ~ 22%, then through at least one squezzing operation, more a kind of wet method bass after carrying out washing and drying, is obtained;
Step 3: dry mixed is prepared burden:
By high-speed stirred after the mixing of 100kg polyurethane dry method resin, 15 ~ 20kg dimethyl formamide, 15 ~ 20kg butanone, 15 ~ 20kg toluene, 0.5 ~ 1.0kg auxiliary agent and 3 ~ 5kg toner, mixing time 10 ~ 15 minutes is to stirring;
Step 4: dry method veneer:
The dry method slurry prepared in step 3 is coated with and scrapes form dry method veneer in release liners, 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: adhesive formulations:
By high-speed stirred after 100kg adhesive glue, 20 ~ 30kg butanone, 10 ~ 14kg bridging agent, the mixing of 3 ~ 5kg promoter, mixing time 10-15 minute, filters stand-by;
Step 6: transfer:
The hair side of step 4 is coated with the adhesive glue scraped step 5 and prepare, and then adhesive transfer film, after stripping, can obtain a kind of two-sided leather.
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 resin is joined in the mixture that step b formed, stir 40 minutes, deaeration 45 minutes.
As a further improvement on the present invention, the speed of a motor vehicle of described step 2 is at 12-15 rice/min, and the speed of a motor vehicle of step 4 is at 20-25 rice/min.
As a further improvement on the present invention, use the release liners with flower pattern in described step 4, in step 6, use the transfer membrane with flower pattern, material is thus formed existing release liners flower pattern, have again the two-sided leather of transfer membrane flower pattern.
The invention has the beneficial effects as follows: the present invention adopts and is made into wet method bass through compiling suede nap as base cloth, dry method veneer is pasted in the side in its light face, transfer membrane is pasted in the side of its hair side, form two front side structure, dry method veneer has the release liners of flower pattern by use and has flower pattern, its transfer membrane also has flower pattern, so just forms existing release liners flower pattern, has again the two-sided leather of transfer membrane flower pattern, it is applied widely, is mainly applicable to two-sided processing of wearing clothes.
