Abstract
The invention discloses a manufacture method of half microfiber sports shoe leather. According to the method, firstly, paint mixed material proportioning of wet process mixing material proportioning is carried out, and then, the impregnation mixing material proportioning of the wet process mixing material proportioning is carried out; next, paint and impregnation mixtures are coated and scrapped onto mesh non-woven fabrics by an impregnation coating and scraping integral method to be cured into films, and wet process bass is obtained through water washing and drying forming; and after dry process material proportioning, the dry process mixtures are coated and scrapped onto parting paper, then, the obtained material is pasted with the front side of the produced wet process bass through bonding agents, and finished products are obtained. The product is more similar to the top layer leather of the real leather, the back side of the synthetic leather has the velvet effect of ultrafine fiber similar to the real leather, the front side of the synthetic leather is provided with polyether resin with high acid and base resistance, the defects of relatively poor elasticity of the ultrafine fiber and serious crease of the leather surface after the flat pattern pasting can be overcome, the ultrafine fiber is more similar to the real leather in the visual and hand feeling aspects, and the product has the advantages that the hand feeling is soft and tough, no bone figure exists, and the physical and mechanical performance is excellent.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of half super fine sports shoe leather preparation method.
Background technology
Leather poor flexibility for current shoemaking, and its inner surface do not have the velvet of corium, needs subsequent handling side laminating therein patterned surface, and after laminating, patterned surface is easily wrinkling.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of half super fine sports shoe leather preparation method, half super fine sports shoe leather preparation method technique is simple for this, the product good springiness of producing, feel is pliable and tough, without bone line, physical and mechanical properties is outstanding, close to the first layer lether of corium.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of half super fine sports shoe leather preparation method, and concrete steps are as follows:
Step 1: wet-mixing batching:
Coating mix:
A. by 5～10kg dimethyl formamide and 3～7kg wet method hydrolysis mill base high-speed stirred 15～20 minutes, then filter static stand-by;
B. by 20～55kg dimethyl formamide, 0.5～3kg hydrolysis auxiliary agent and 0.5～2kg surfactant mix and blend 15～20 minutes;
C. the mixture in step a is stirred again after 5～15 minutes, add 100kg wet method high hydrolysis resistance regenerating polyurethane resin to stir at the temperature of 20 DEG C-40 DEG C within 2 hours, to make it fully mix after negative pressure vacuumize and filter static, froth breaking is stand-by;
Impregnation mix:
D. by 10～15kg dimethyl formamide and 5～15kg wet method hydrolysis mill base high-speed stirred 15～20 minutes, then filter stand-by;
E. after 20～30 minutes, add 0.5～2kg surfactant and steps d neutralise mixt to stir 30～50 minutes 100kg wet method high hydrolysis resistance regenerating polyurethane resin and 180～385kg dimethyl formamide high-speed stirred, static stand-by;
Step 2: wet method bass is produced:
Half super fine nonwoven cloth clamp screen cloth whole boiling hot processing at the temperature of 100 DEG C-150 DEG C, the method of then mixture forming in step 1 being scraped to one by containing dip-coating is coated with to scrape on folder net nonwoven fabric and (first will after coating impregnation, will directly be coated with and scrapes), then by the displacement after coagulation film forming of organic solvent and water, through washing, drying and shaping (thickness can according to product requirement control), described bake out temperature is controlled at 100～150 DEG C again;
Step 3: wet method bass processing: the wet method bass back side the having produced napping of polishing, then carry out the processing of oily cured sense of touch by the method for anilox roll material loading, the wet method bass back side just has the velvet that oil is puckery like this, and its thickness can be adjusted according to product requirement;
Step 4: dry mixed batching:
90kg high hydrolysis resistance dry method polyurethane resin, 5～15kg dimethyl formamide, 10～20kg toluene, 10～20kg butanone, 15～30kg dry method hydrolysis mill base and 0.1～1kg surfactant are mixed and put into homogenizer it is stirred, and mixing time is 50～70 minutes;
Step 5: dry method veneer is produced:
Mixture in step 4 is coated with and is scraped in release liners, then by the positive laminating of adhesive and the wet method bass of producing, so just the wet method bass of production is become to the finished product of the sports shoe leather of artificial leather decorative pattern through the method for dry method release liners transfer veneer;
Step 6: inspection, packaging:
Gained finished product in step 5 is checked according to test stone and packed in packing case.
As a further improvement on the present invention, the mixture that in described step 1, the dimethyl formamide of the step b of coating mix, hydrolysis auxiliary agent and surfactant form is uniformly mixed in the reactor that can take out negative pressure.
As a further improvement on the present invention, the step c of the coating mix in described step 1 is carrying out in the reactor that can take out negative pressure.
As a further improvement on the present invention, described in step 2, half the density of super fine nonwoven fabric is 300-320g/m
2.
As a further improvement on the present invention, described release liners is dapple release liners.
The invention has the beneficial effects as follows: the product that the present invention produces is closer to the first layer lether of corium, the back side of synthetic leather has the velvet of the superfine fibre of similar corium, there is the polyether resin of high acid-fast alkali-proof in front, its alternative super fine elasticity is relatively not so good and develop decorative pattern and the wrinkling serious shortcoming of leather surface, from vision and feel closer to corium, this product feel is pliable and tough, and without bone line, physical and mechanical properties is outstanding.
