The present invention relates to a kind of footwear material, more particularly, relate to the heel of footwear or the footwear material that head is used.
Prior art
People will appreciate that surely, obtain for the purpose of good appearance and the profile in order to guarantee footwear, heel and head are set up stiffener gear to actual circumstances.Generally speaking, the stiffener of heel is meant heel (counter), and the stiffener of head then can be called capouch (boxed toe) or toe cap top (toe puff).Obviously, in some protectiveness footwear, toe cap top is available very has an inflexible steel toe-cap (toe cap) and substitutes, so that protection to be provided.What should emphasize is, no matter is heel, or the toe cap top is for the protection pin designs, but in general produce and market process for guaranteeing that footwear have good profile.
Before, some footwear reinforcement material had been made with the thermoplastics of extruding always, scribbled binding agent on it, was beneficial to location in footwear nation parts (footwear upper component).As everybody knows, reinforcement material has thermoplasticity, so can be shaped in each operation of footwear manufacturing.Generally reinforcement material is wrapped on the model and heat, form required heel shape, cooled off subsequently, make reinforcement material and last footwear nation keep formed shape.
Aforesaid reinforcement material is made generally in sheet, becomes desired shape by this sheet material crush-cutting again.Therefore, after sheet material is cut out out toe-cap spare or heel, will be left the big area sheet material.This scrap stock can be up to 20% of sheet material area.Obviously, utilize this sheet material as far as possible more, perhaps reclaim and reuse the corner sheet material, will be more economically.Regrettably, if the sheet material that will give up is pulverized and is extruded into pellet again, in being processed into the process of sheet material, handling the binding agent that is coated with on the reinforcement material and can run into trouble.
The purpose of this invention is to provide a kind of energy and reclaim the reinforcement material composition of the shoemaking of reusing.
Technological improvement
A kind of reinforcement material of shoemaking, this material comprise by weight a kind of softening temperature of 60～80% within 80～90 ℃ of scopes and 230 ℃ the time viscosity be about the main adhesive components of 1000 pools, a kind of softening temperature between 0 and 15% within 90～120 ℃ of scopes and 150 ℃ the time viscosity be about the copolyester tackiness agents of 50～10000 pools, a kind of mineral filler in 15～30% (weight) scope, and a kind of pigment that accounts for this material weight 3% at the most, this reinforcement material is squeezed into sheet material, have enough bond propertiess that can be bonded on the upper component, and can be lower than thermoforming under 90 ℃ the temperature, form the reinforcing element of footwear.
Preferably, main adhesive component is a line style saturated polyester binder/adhesive (binder/-adhesive), for example tired this spy's (city, prefecture) of Britain Bostik HM5584AE that company limited produces or Esterpons1112AF.Described mineral filler can be 60 order micas (Mica60mesh).The copolyester tackiness agent can be Bostik " T " tackiness agent or the Griltex8 tackiness agent that EMS-Chemi company is produced.Described pigment can be titanium dioxide.
The thickness of extruded material is at most 1.5mm, decides on the situation of the required necessary stiffener of footwear.
Only illustrate the present invention below.
Invention embodiment and operation embodiment
What it will be understood that is, stiffener from the sheet material under the cutting after, with regard to recyclable heel material of reusing, waste material should be pulverized, the co-extrusion granulation.Therefore, reinforcement material is homogeneous preferably, so just needn't be coated with bonding coat reinforcement material is adhered on the footwear parts.Thereby, having only temperature is brought up to more than the temperature of fusion, particle that makes recovery etc. strikes up partnership, and could reclaim and reuse useless reinforcement material.
Among the present invention, utilize the combination of primary binder component or line style saturated polyester binder/adhesive and copolyester tackiness agent, form the thermoformable material, as the reinforcement material core.For making reinforcement material possess necessary stiffness, wherein add mineral filler, it is measured to can make reinforcement material obtain the necessary group component of required stiffness.In addition, also add a kind of filler such as titanium dioxide, so that solid colour.
Preferred line style saturated polyester is produced Bostik HM5584AE by the Bostik company limited of Britain Leicester among the present invention.Principal constituent is this hot-melt adhesive/tackiness agent of polyester, with the pulverulence supply, and can use under quite low temperature, forms not only to have rigidity but also a tool flexible material.The softening temperature of this HM5584AE binder/adhesive is within 80 ℃～90 ℃ scopes, and the viscosity in the time of 230 ℃ is about 1000 pools.Original granularity is within 100～600 μ m distribution ranges in the powder.
Preferred copolyester tackiness agent is produced Bostik " T " tackiness agent by tired this spy's (city, prefecture Leicester) of Britain Bostik company limited among the present invention.The viscosity of this copolyester in the time of 150 ℃ is at most 10000 pools, and temperature of fusion is within 90～120 ℃ of scopes.It is reported that this copolyester tackiness agent has the trend of higher melting temperature than saturated line style polyester binder, thereby under the heat-activated condition, consistent with usual phenomenon, softening degree is less.
For making reinforcement material have stiffness, must add a kind of filler, this filler is generally the mineral-type filler, and is cheap because of it.Preferred mineral filler is Mica60 among the present invention, but also available talcum or clay.
This area the professional all know, the actual weight of above-mentioned each component is formed and can be changed within the scope of the present invention.Yet, importantly,, reinforcement material reuses if must reclaiming fully, during shoemaking, must between itself and upper of a shoe under the permissive temperature, should have enough cohesive forces, make it after thermoforming, to obtain suitable stiffness.Have now found that, use following weight to form and just can obtain acceptable performance: line style saturated polyester 60～70%, copolyester tackiness agent 5～15%, mineral filler 15～30%, and the pigment of the packing type that additionally can be at the most 3%.Preferably consist of line style saturated polyester component 65%, copolyester component 10%, mineral filler 22.5% and pigment (titanium dioxide) 2.5%.
Know also that as people stiffness and the necessary temperature of mold pressing that reinforcement material thickness obviously influences this material and reached are so the thickness after this material extruding is at the most in the 1.5mm scope.But because the uniformity of reinforcement material of the present invention, this outer surface all has tackiness agent/adhesive properties to any upper component on the other side.In addition, these upper components generally are used in the heel element that is cut into or the reinforcement material of toe element and fit in the reinforcing down of heating.
People know that line style saturated polyester component can substitute with polycaprolactone, as the primary binder component.
With regard to recovery is reused, behind the cutting parts the useless reinforcement material of gained pulverized, granulation or directly place the extrusion machine loading hopper, and give remelting.Then, the reinforcement material that reclaims is squeezed into the state of original unworn extruded sheet.
Obviously, available 100% salvage material forms sheet material again.Yet, though this salvage material through granulation, always has pollutent, for example oil.This pollutent is harmful to the performance of stiffening material in footwear rear portion or the toe cap top, uses with new reinforcement material and extrudes thereby generally will reclaim particle etc.A shoe pattern product that arch upward of footwear material of the present invention contain Bostik HM5584AE65%, Bostik " T " tackiness agent 10%, mica 60 order 27.5% and TiO by weight
22.5%, its thickness is 1.3mm, bears a heavy burden to be 1990g/m
2, record its initial deformation intensity, also promptly subside and locate to be 13.6kg at first vault, after subsiding, 10 vaults are 5.9kg.
Also can understand, but as a kind of system of selection of cutting footwear strengthening part from sheet material, but deposited powder forms parts.This powder that contains each component of reinforcement material can directly be deposited on the parts of footwear or use on the product of transfer method.The loss prevention sheet of powder deposition or haftplatte not above can comprising, this transfer device are arranged.
The general using stencil of powder deposits; The thickness of template has determined the thickness of powder and the thickness of gained reinforcement material.In case after the deposition, powder strikes up partnership through heat-activated, thereby form reinforcement material.In case after the cooling, reinforcement material can heat reactivate, is molded into footwear inside.When adopting transfer method, the reinforcement material that is shaped with template all can be transferred on the footwear after cooling or when still hot.
