Abstract
The present invention discloses a method for manufacturing netted sandwich cloth synthetic leather, including: stirring uniformly and filtering dimethylformamide and wet hydrolysis resistance paste; then continuously stirring for 5-15 minutes, adding the wet high hydrolysis resistance recycled polyurethane resin, mixing and defoaming; stirring dimethylformamide, a hydrolysis resistance additive and a surfactant uniformly; stirring and filtering the dimethylformamide and the wet hydrolysis resistance paste for standing by; stirring the wet high hydrolysis resistance recycled polyurethane resin and dimethylformamide uniformly, adding the surfactant and the former mixture to stir uniformly, scraping the mixture on the netted sandwich cloth by a method integrating dipping, coating and scraping in one, solidifying to form film, washing and drying to fix the shape to get wet base, stirring high hydrolysis resistance dry polyurethane resin, dimethylformamide, toluene, butanone, dry hydrolysis resistance paste and the surfactant, scraping and coating the mixture on release paper, and then adhering the wet base. 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 a kind of folder screen cloth synthetic leather preparation method.
Background technology
The base cloth of the high density leather that the sport footwear of present specific function is used all only is that nonwoven fabric and wet method mixed with resin form, and the percentage elongation of this kind structure base cloth is large, and sport footwear is yielding through the external force extruding, in use easily appearance fracture line.
Summary of the invention
In order to overcome defects, 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 of producing is little, and is not yielding by its sport footwear of making, is not prone to the fracture line, elasticity is good, and sense of fullness is strong.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of folder screen cloth synthetic leather preparation method, and concrete steps are as follows:
Step 1: wet-mixing batching:
The coating mix:
A. with 5～10kg dimethyl formamide and 3～7kg wet method hydrolysis mill base high-speed stirred 15～20 minutes, then filter stand-by;
B. with 20～55kg dimethyl formamide, 0.5～3kg hydrolysis auxiliary agent and 0.5～2kg surfactant mix and blend 15～20 minutes;
C. the mixture among the step a is stirred again after 5～15 minutes add 100kg wet method high hydrolysis resistance regenerating polyurethane resin stir under 20 ℃-40 ℃ the temperature it was fully mixed in 2 hours after negative pressure vacuumize and filter static, froth breaking is stand-by;
The impregnation mix:
D. with 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 and stirred 30～50 minutes, static stand-by;
Step 2: the wet method bass is produced:
With the whole boiling hot processing under 130 ℃～180 ℃ temperature of folder screen cloth, the method of then mixture that forms in the step 1 being scraped one by containing dip-coating is coated with and scrapes on the folder net nonwoven fabric (directly be coated with after the first impregnation and scrape), then the displacement after coagulation film forming by organic solvent and water, through washing, drying and shaping (thickness can be controlled according to product requirement), described bake out temperature is controlled at 100～150 ℃ again;
Step 3: 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 mixed put into homogenizer it is stirred, mixing time is 50～70 minutes;
Step 4: the dry method veneer is produced:
Mixture in the step 3 is coated with scrapes on release liners, the wet method bass of then fitting and having produced by adhesive makes it become the finished product of the sports shoe leather that the artificial leather decorative pattern is arranged through the method that the dry method release liners shifts veneer the wet method bass of producing like this;
Step 5: check, packing:
Gained finished product in the step 4 checked according to test stone and the packing case of packing in.
As a further improvement on the present invention, the mixture that the dimethyl formamide of the step b of coating mix, hydrolysis auxiliary agent and surfactant form in the described step 1 mixes 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 the described step 1 is carrying out in the reactor that can take out negative pressure.
As a further improvement on the present invention, described folder screen cloth enters in the nonwoven fabric in 10%～20% woven fabric acupuncture and forms for will be clipped in percentage elongation in the middle of the two-layer nonwoven with the method for acupuncture.
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 has overcome 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 of producing is similar to high density product, the percentage elongation of this base material can accomplish through, the level that the 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, behind the veneer of dry method, can be directly used in sports shoe leather, this product has solved the problem of the fracture line that high density product in the past brings because of nonwoven fabric, its elasticity is good, and sense of fullness is strong.
