Abstract
A kind of polyvingl butyral synthetic leather, being soaked with the polyvinyl butyral resin by non-woven fabrics of synthetic fiber is that the latex mixing of major ingredient forms.Its rigidity is good, and the intensity height is ventilative, water-fast, can replace natural leather and other substitute materials to do leather shoes master attendant of a stage actor head and shoe lining.Chance water is indeformable, keeps leather shoes attractive in appearance, wears comfortable.And make easily, technology is simple, and is pollution-free, and cost is low, and activity function is good, easily processing.Be desirable making footwear with main substitute material with, packet header and shoe lining.Can reduce the shoemaking cost, improve the performance that wears of footwear.
Description
A kind of wet polyvingl butyral synthetic leather.
The invention belongs to chemical industry technical field synthetic leather class, be mainly used in the master who makes leather shoes and follow packet header and shoe lining.
For the leather shoes shape that makes making is attractive in appearance, indeformable, comfortable and easy to wear, used master will have certain rigidity and intensity with, packet header material, and requires ventilatively, meets water and keeps the shape.The used master of leather shoe industry follows at present, and the packet header substitute material has two kinds, and the one, nonwoven fabric soaks the substitute material that the polyvinyl acetate latex mixing is made, the dry method operation, moderate cost, but the rigidity difference is met the water distortion, and airtight, the phenomenon that is clamminess can appear in the use in summer.Another kind of material is that nonwoven fabric soaks the substitute material that the polystyrene latex mixing is made, the dry method operation, and rigidity is good, the intensity height, but airtight, price height and raw material are in short supply.
The objective of the invention is to select a kind of material water-fast, ventilative, that rigidity is good to replace natural leather used in the shoe industry or other substitute materials to decide and follow toe cap (packet header).It is base material that the present invention has selected non-woven fabrics of synthetic fiber for use, and soaking with the polyvinyl butyral resin resin is the wet polyvingl butyral synthetic leather that the latex mixing of major ingredient is made.This synthetic leather is water-fast, ventilative, rigidity good, intensity is high, price is low and easy processing.Can replace in the shoe industry employed natural leather and other substitute materials to decide and follow packet header and shoe lining.Can reduce the shoemaking cost, improving leather shoes, to wear performance promptly comfortable and easy to wear, shape invariance.
Content of the present invention is to be base material with the non-woven fabrics of synthetic fiber, and soaking with the polyvinyl butyral resin is the synthetic leather that the latex mixing of major ingredient forms.Its technological process is:
(1) glue configuration
(3) washing → (5) drying → (using cement dipping machine) (40-50 ℃ of water) (80-95 ℃) solidified in impregnation → (4)
(2) base material treatment
(6) ironing → (7) arrangement → finished product
(90-100 ℃) (outward appearance arrangement)
(1) preparation of glue
Main Ingredients and Appearance and counterweight ratio are: (%)
Polyvinyl butyral resin resin 6-7
Phenolic resin 1-2
Precipitated calcium carbonate 15-17
Talcum powder 3-5
Silica flour 5-7
Ethanol 60-70
Butanone 2-4
Dispersant is an amount of
Age resistor is an amount of
Mould inhibitor is an amount of
The preparation of dipping solution: in the reactor of belt stirrer, polyvinyl butyral resin resin, phenolic resin are dissolved in ethanol, the butanone make resin glue earlier.Add other fillers and auxiliary agent more respectively, constantly stir.
(2) base material treatment: shrink in advance in the thermal contraction jar under 120-140 ℃ of condition.
(3) impregnation: use the cement dipping machine impregnation, note soaking into.
(4) solidify washing: the base material behind the impregnation is put in 40-50 ℃ water-borne glue liquid chance water after coagulation, and solvent is soluble in water to be used so that reclaim again.Safety non-pollution.
(5) drying: enter through type drying machine drying after the washing, between temperature keeps 80-95 ℃.
(6) ironing is shunk: carry out on dull and stereotyped ironing machine, the working plate temperature remains on 90-100 ℃.
(7) arrangement: outward appearance arrangement.
Technology of the present invention is simple, and cost is low.The whole production line speed of production is 1.4 meters/minute.
The present invention adjusts proportioning, when the ratio of filler is the 4-8% of latex gross weight, can be made into the synthetic leather of soft type.Its performance be water-fast, ventilative, soft, intensity is high.Can be used for making the shoe lining of sport footwear, playshoes and other footwear.
Embodiments of the invention are made main attendant of a stage actor's head synthetic leather sample in April, 1989, and Beijing's leather quality supervision measuring station is as follows to institute's feeding sample " main attendant of a stage actor's head " quality inspection result:
Tensile strength (N/mm
2) 22.5
Tearing strength (N/mm) 65.7
Vapor pervious (mg/cm
2) 90.68
Percentage elongation (%) 34
Water absorption rate (%) 26.6
Weight (g) 1.844
Thickness (mm) 1.15
Density (g/cm
3) 1.17
Therefore should invention water-fast, ventilative, rigidity is good, intensity is high, cost is low, easily process, be good material required in the shoe industry, and manufacturing technique is easy, pollution-free, conservation.
