B, add 180-280kg dimethyl formamide to stir 80-100kg high hydrolysis resistance polyurethane resin, after standing 20-45 minute with a material mixture stir filter stand-by;
Step 2: be coated with scraper preparation;
C, 5-10kg dimethyl formamide, 5-10kg hydrolysis mill base, 0.5-3kg wet method hydrolysis auxiliary agent and 15-30kg wood powder high-speed stirred is even, filters stand-by;
D, 80-100kg high hydrolysis resistance polyurethane resin and 50-80kg dimethyl formamide are stirred, standing 20-45 minute, then with step c in the mixture of gained stir, then deaeration, temperature is controlled 20 ℃-40 ℃, then filters staticly, froth breaking is stand-by;
Step 3: select nonwoven fabric;
Step 4: wet method bass is produced:
By the nonwoven fabric of choosing fully containing being immersed in the middle of the impregnation material having filtered, then the dimethyl formamide aqueous solution of putting into mass percent concentration and be 15-30% solidifies, through extruding, dry the painting scraper that evenly applies again deaeration after half-dried, the dimethyl formamide aqueous solution of putting into mass percent concentration and be 20-30% fully solidifies, and through multiple tracks squezzing, washing, after dry, makes a kind of handball leather wet method bass;
Step 5: embossing post processing:
First the above-mentioned handball leather wet method bass of producing is carried out to scratch resistance surface treatment; Then the handball leather wet method bass of handling well is carried out to embossing with flower rod; Again the handball leather wet method bass after embossing is carried out to puckery feel surface treatment.
As a further improvement on the present invention, described nonwoven fabric is selected spunlace non-woven cloth.
As a further improvement on the present invention, the mixture high-speed stirred 60-90 minute of step a in described impregnation material preparation process.
As a further improvement on the present invention, the mixture high-speed stirred 30 minutes of step b in described impregnation material preparation process.
As a further improvement on the present invention, the mixture high-speed stirred 60-90 minute of step c in described painting scraper preparation process.
As a further improvement on the present invention, mixture mix and blend and deaeration in the reactor of negative pressure vacuum-pumping in the steps d of described painting scraper preparation process, mixing time is 2 hours.
As a further improvement on the present invention, the speed of a motor vehicle that described step 4 wet method bass is produced is controlled at 6-12m/min.
The invention has the beneficial effects as follows: the present invention mainly adopts high hydrolysis resistance polyurethane resin to prepare wet method bass, its surface is through scratch resistance, embossing and puckery feel surface treatment, the handball leather of its production has that high hydrolysis resistance, flower type are clear, good hand feeling, is difficult for the advantage of landing during use.
