The product produced by the present invention is high in density, low in elongation, difficult to produce fracture lines, good in flexibility, and high in fullness sense.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly one folder screen cloth synthetic leather preparation method.
Background technology
The Ji Bu of the high density leather that the sport footwear of current specific function is used is only that nonwoven fabric and wet method mixed with resin are formed, and the percentage elongation of this kind of structure base cloth is large, and sport footwear is yielding through external force extruding, in use easily occurs fracture line.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of folder screen cloth synthetic leather preparation method, this folder screen cloth synthetic leather preparation method technique is simple, the product percentage elongation produced is little, and the sport footwear be made up of it is not yielding, not easily occurs fracture line, elasticity is good, and sense of fullness is strong.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of folder screen cloth synthetic leather preparation method, and concrete steps are as follows:
Step one: wet-mixing is prepared burden:
Coating mix:
A. by 5 ~ 10kg dimethyl formamide and 3 ~ 7kg wet method hydrolysis mill base high-speed stirred 15 ~ 20 minutes, then filter 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. add after the mixture in step a being stirred 5 ~ 15 minutes again 100kg wet method high hydrolysis resistance regenerating polyurethane resin stir at the temperature of 20 DEG C-40 DEG C within 2 hours, 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. 100kg wet method high hydrolysis resistance regenerating polyurethane resin and 180 ~ 385kg dimethyl formamide high-speed stirred are added 0.5 ~ 2kg surfactant and steps d neutralise mixt after 20 ~ 30 minutes to stir 30 ~ 50 minutes, static stand-by;
Step 2: wet method bass is produced:
By the whole boiling hot process at the temperature of 130 DEG C ~ 180 DEG C of folder screen cloth, then the mixture formed in step one is coated with to scrape on folder net nonwoven fabric by the method for scraping one containing dip-coating and (is directly coated with after first impregnation and scrapes), then by the displacement after coagulation film forming of organic solvent and water, again through washing, drying and shaping (thickness can control according to product requirement), described bake out temperature controls at 100 ~ 150 DEG C;
Step 3: dry mixed is prepared burden:
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 and make it stir, mixing time is 50 ~ 70 minutes;
Step 4: dry method veneer is produced:
Being coated with by mixture in step 3 scrapes in release liners, then to be fitted the wet method bass produced by adhesive, like this wet method bass of production is become the finished product of the sports shoe leather of artificial leather decorative pattern through the method for dry method release liners transfer veneer;
Step 5: inspection, packaging:
Gained finished product in step 4 is carried out checking and loading in packing case according to test stone.
As a further improvement on the present invention, the mixture that in described step one, the dimethyl formamide of the step b of coating mix, hydrolysis auxiliary agent and surfactant are formed is uniformly mixed in the reactor can taking out negative pressure.
As a further improvement on the present invention, the step c of the coating mix in described step one is carrying out in the reactor can taking out negative pressure.
As a further improvement on the present invention, described folder screen cloth is enter in nonwoven fabric with the method for acupuncture formed being clipped in the woven fabric acupuncture of the percentage elongation in the middle of two-layer nonwoven 10% ~ 20%.
As a further improvement on the present invention, described release liners is dapple release liners.
The invention has the beneficial effects as follows: the sports shoe leather that the product that the present invention produces overcomes specific function makes the sport footwear of making through the excessive shortcoming of external force crimp because percentage elongation is excessive, process through wet method, the high hydrolysis resistance base material produced is similar to high density product, the percentage elongation of this base material can accomplish through, the level that weft direction stretch rate is basically identical, and other physical property are analogous to the physical property of the high density product on our conventional meaning substantially, sports shoe leather can be directly used in after the veneer of dry method, this product solves the problem of the fracture line that high density product is in the past brought because of nonwoven fabric, its elasticity is good, sense of fullness is strong.
