Abstract
A disclosed preparation method of handball leather comprises: uniformly mixing 5-10 parts by weight of dimethyl formamide, 2-10 parts by weight of a hydrolysis-resistant color paste, 0.5-2 parts by weight of a surfactant, 80-100 parts by weight of high-hydrolysis-resistance polyurethane resin and 180-280 parts by weight of dimethyl formamide to obtain an immersing material; uniformly mixing 5-10 parts by weight of dimethyl formamide, 5-10 parts by weight of a hydrolysis-resistant color paste, 0.5-3 parts by weight of a wet-method hydrolysis-resistant auxiliary agent, 15-30 parts by weight of wood powder, 80-100 parts by weight of high-hydrolysis-resistance polyurethane resin and 50-80 parts by weight of dimethyl formamide to defoam, and standing to defoam and further to obtain a coating material; immersing non-woven fabrics in the immersing material, solidifying, squeezing, drying to half dryness, then coating with the coating material, solidifying with a dimethyl formamide aqueous solution, squeezing out water, washing with water, drying to obtain wet-method bass; performing scrape-resistant surface processing and embossing; and finally performing pucker-hand-feeling surface processing to obtain the handball leather. The obtained handball leather has the advantages of being high in hydrolysis resistance, clear in pattern, good in hand feeling and not easy to creep down.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of Preparation method of handball leather.
Background technology
Team handball is very general at present, and traditional handball makes with the pure chromium boots leather do not dyeed or cover with paint, lacquer, colour wash, etc., and raw material generally adopts cattle hide to process through kinds of processes, its cost is high, complex procedures, is difficult to processing, also has at present and adopts common PU leather embossed surface making handball to remove from office, its cost is low, make simple, but its poor flexibility, and feel is stiff, its skin-friction force is less, is easy to landing after being made into handball.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Preparation method of handball leather, this Preparation method of handball leather production technology product that is simple, that produce has that high hydrolysis resistance, flower pattern are clear, good hand feeling, the advantage of not easily landing during use.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of Preparation method of handball leather, and concrete steps are as follows:
Step one: impregnation material is prepared:
A, 5-10kg dimethyl formamide, 2-10kg hydrolysis mill base and 0.5-2kg surfactant high-speed stirred is even, filter stand-by;
B, 80-100kg high hydrolysis resistance polyurethane resin added 180-280kg dimethyl formamide stir, leaving standstill stirred with a material mixture after 20-45 minute 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, filter stand-by;
D, 80-100kg high hydrolysis resistance polyurethane resin and 50-80kg dimethyl formamide to be stirred, leave standstill 20-45 minute, then stir with the mixture of gained in step c, then deaeration, temperature controls 20 DEG C-40 DEG C, and then filter static, froth breaking is stand-by;
Step 3: select nonwoven fabric;
Step 4: wet method bass is produced:
By the nonwoven fabric chosen fully containing being immersed in the middle of the impregnation material that filtered, then putting into mass percent concentration is that the dimethylformamide in water of 15-30% solidifies, through extruding, dry half-dried after evenly apply the painting scraper of deaeration again, putting into mass percent concentration is that the dimethylformamide in water of 20-30% fully solidifies, obtained a kind of handball leather wet method bass after multiple tracks squezzing, washing, drying;
Step 5: embossing post processing:
First the above-mentioned handball leather wet method bass produced is carried out scratch resistance surface treatment; Then the handball handled well leather wet method bass flower rod is carried out embossing; Again the handball leather wet method bass after embossing is carried out puckery feel surface treatment.
As a further improvement on the present invention, spunlace non-woven cloth selected by described nonwoven fabric.
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 controls 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, its handball leather produced has that high hydrolysis resistance, flower pattern are clear, good hand feeling, the advantage of not easily landing during use.
