Description
Technical field
The present invention relates to a kind of preparation method of PVC mildew-resistant fragrance luggage leather.Belong to the artificial leather technical field.
Background technology
The present invention in the past, luggage leather in the past also gives out a kind of distinctive process hides strange taste, and for a long time like this, both had been difficult to maintain case and bag no matter be that PVC leather, PU leather or corium leather are processed neither mildew-resistant behind all kinds of case and bag.Feel that again process hides smells foul, some popular high-grade leisure leather bags particularly go mouldy in the south that plum rain season is moist easily, even and mouldy afterwards shampoo totally also can shading and diminish outward appearance.Always also have no matter be that what leather processes that to have one process hides flavor that the people has been heard behind the bag uncomfortable, sway the emotion, even influence be physically and mentally healthy.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency; A kind of the same artificial PVC luggage leather of corium that both had is provided; And this artificial PVC leather had both had antimicrobial properties after processing all kinds of case and bag; Do not play mould and the tool antimildew function, can have the preparation method of the PVC mildew-resistant fragrance luggage leather of fragranced again for a long time.
The objective of the invention is to realize like this: a kind of PVC mildew-resistant fragrance luggage leather, said method comprises following processing step:
Knitted cloth is opened cloth through the planting-opener gluing handle, glue amount 3 ~ 4 grams/square metre, 65 ~ 80 meters/minute of machine speeds,
100 parts of weight portions of polyvinyl chloride resin, 25 parts of weight portions of dibutyl ester and antimicrobial polymerizable agent 0.8 weight portion are added mixer together; Be heated to 115 ~ 130 ℃, stir, the entering banbury is heated to 170 ~ 180 ℃ and tentatively plastifies; Get into two roller mills maintain the temperature at 170 ~ 180 ℃ proceed the plasticizing; Get into 160 ~ 170 ℃ of further plasticizings of extruder, and carry out getting into four-roll calender behind the contaminant filter, keep temperature to roll into the printing facial mask for 180 ~ 190 ℃; Subsequent use through five rollers cooling rolling again, 60 ~ 75 meters/minute of calender machine speeds.
Step 3, prepare colored facial mask
The printing facial mask of step 2 preparation is subsequent use through the rolling of printing machine intaglio plate chromaticity printing rolling after cooling machine by product regulation requirement color and luster, pattern, and the winder machine speed is at 75 ~ 90 meters/minute.
Polyvinyl chloride resin 100 weight portions, dibutyl ester 25 weight portions, aromatic additive 0.15 weight portion and precipitated calcium carbonate 35 weight portions are added mixer together; Be heated to 105 ~ 120 ℃; Stir, get into banbury and be heated to 160 ~ 180 ℃, tentatively plastify; Get into two roller mills and keep 160 ~ 180 ℃ of temperature; Continue to plastify, get into extruder again and keep 160 ~ 170 ℃ of further extruding plasticizings of temperature, and the entering four-roll calender keeps 170 ~ 180 ℃ of temperature to roll into PVC leather aroma type basement membrane after carrying out contaminant filter.
Base cloth, basement membrane and colored facial mask are in the same place through last roller heat seal of four roller machines.Temperature is 170 ~ 180 ℃, 60 meters/minute of speed, and heat seal is after five rollers cooling rolling.
Step 6, acupuncture
The colored facial mask and the basement membrane that fit together are pierced through perforation, let the fragranced in the basement membrane come out well through countless pin holes.
Step 7, post processing
Semi-finished product after through post-processor acupuncture being handled carry out the embossing shrinkage cavity to be handled; Be heated to 155 ~ 170 ℃; Make the pin hole on the PVC leather surface shorten the invisible micropore of naked eyes into and have corium lines etc. through the high temperature plasticizing, cooling is wound into finished product, 70 ~ 80 meters/minute of speed.
The invention has the beneficial effects as follows:
(1) has antimildew function.
(2) has the long-acting aromatic function that distributes.
