The method consists of the control to raw materials, appearance and physical and mechanical properties, wherein, the raw materials comprise standard natural ruuber, carbon soot with high wear resistance, zinc oxide, stearic acid, accelerant DM, accelerant M, sulfur, space-variant terylene filament canvas and terylene filament flat hair plush; the appearance comprises the appearance of an upper semifinished product and the appearance of a finished shoe; the physical and mechanical properties comprise the bond strength of the upper with a foxing, the wear-resisting performance of external bottom, the strength and elongation performance of the external bottom, the hardness of a glue component, aging performance of glue stuff and the air permeability and the moisture permeability of the upper. The invention establishes a novel quality controlling method for a pair of cloth cover moulded shoes, improves the quality control standard of moulded shoes and ensures the performances of the moulded shoes better, such as the comfortableness for wearing, the wearing resistance, etc.
Description
Technical field
The present invention relates to the molded shoes with cloth cover technical field, particularly relate to the method for quality control of molded shoes with cloth cover.
Background technology
Molded shoes with cloth cover is the molded vulcanization structure, comprises single footwear of cloth cover mold pressing and cloth cover mold pressing cotton-padded shoes, because its practicality comfortable and easy to wear, light, and the outward appearance leisure is generous, and be subjected to consumer's favor deeply.
The preparation method of cemented shoe is:
1, make semi-finished product: the textile material that will meet specification requirement is made upper of a shoe, is used for the moulding manufacturing through after the assay was approved; Simultaneously, the chemical raw material and the rubber that are up to the standards are made cemented shoe glue component elastomeric compound on rubber mixing machine, make semi-finished product film and bonding rubber cement with elastomeric compound afterwards.
2, the moulding manufacturing of cemented shoe: earlier the end in qualified upper of a shoe and the nonwoven is sewed up, then the upper of a shoe of sewing up is enclosed within on the shoe tree through processing such as typing, swabbings.Again the swabbing upper of a shoe is enclosed within on the sulfuration shoe tree, stick the semi-finished product glue component after, under uniform temperature and pressure, the sulfuration of glue component and upper of a shoe is fixed together, form moulded footwear.At last moulded footwear is modified the making that cemented shoe is promptly finished in processing.
The shaping characteristic of cemented shoe is a sulfidization molding, saves space, simplifies working process, and has energy-conservation, characteristics of high efficiency, and the processing technical parameter is 6～7 minutes molding sulfuration time, and sulfide stress 12～17MPa, curing temperature are 140～155 ℃.
At present, what the quality control of molded shoes with cloth cover was adopted is the national standard of ordinary movement footwear, because ordinary movement footwear national standard is a kind of extensive adaptive standard, specific aim is not strong, performance requirement to footwear is not high, have only two to three months by the cemented shoe life-span of this standard production, and the life requirements of cemented shoe is more than 6 months.Do not meet the client to the cemented shoe outward appearance and wear the demand in life-span according to the cemented shoe of the standard production of ordinary movement footwear, can not form the market competitiveness, value of the product is low, and the various performances of molded shoes with cloth cover comprise that degree comfortable and easy to wear and anti-wear performance etc. all have much room for improvement.Also there is not authoritative method for controlling quality of molded shoes with cloth cover at present.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that the various performances that do not have special method for controlling quality of molded shoes with cloth cover, molded shoes with cloth cover in the prior art have much room for improvement, a kind of special method of quality control at molded shoes with cloth cover is provided, this method has improved the quality of cemented shoe in all its bearings, better guarantee the performances such as degree comfortable and easy to wear, wearability of cemented shoe, can be used as the standard of producing that instructs.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Method for controlling quality of molded shoes with cloth cover is by the outward appearance of raw material, footwear and the quality control of its physical and mechanical properties are formed, wherein, to raw-material quality control be the quality of control criterion natural rubber, high wear-resistant carbon black, zinc oxide, stearic acid, altax, captax, sulphur, space-variant polyester filament canvas and polyester filament straight snips suede; The control of footwear outward appearance comprises the check control to upper of a shoe semi-finished product outward appearance and product shoes outward appearance; Control to the physical and mechanical properties of footwear is the control of bonding strength, outer bottom anti-wear performance, outer bottom strength and extension property, glue component hardness, sizing material ageing properties, upper of a shoe permeability and water vapour permeability to upper of a shoe and foxing.
The control of the physical and mechanical properties described in the above-mentioned method for controlling quality of molded shoes with cloth cover is formed by following:
The bonding strength of upper of a shoe and foxing is not less than 5.0KN/m; (GB/T 532)
The outer bottom anti-wear performance: the Akron wear volume is not more than 0.8cm
3/ 1.61km; (GB/T 1689)
Outer bottom strength and extension property: hot strength 〉=13.0MPa, elongation at break 〉=450%; (GB/T 528)
Glue component hardness: 57 ± 5 degree (Shao Er A type hardness tester); (GB/T 531)
Sizing material ageing properties: i.e. percentage rate of change after the 100 ℃ * 12h hot air aging, hot strength 〉=-20%, elongation at break 〉=-35%; (GB/T 3512)
Upper of a shoe air penetrability 〉=45mm/s; (GB/T 5453)
Upper of a shoe or insole sock vapor transfer rate 〉=4500g/m
2D.(GB/T12701)
More than the control of various performances all be to adopt state's calibration method, the method code name is seen in the bracket.
