Description

A kind of upper of a shoe sheet compound structure of footwear boots

Technical field

The utility model provides a kind of more convenient manufacturing, and the upper of a shoe sheet that can effectively reduce the thermocompression forming temperature, and it can apply on riding boots, snow boots, sweet footwear and sandals or the like footwear boots widely.

Background technology

Please with reference to Fig. 1, it discloses a kind of common sweet footwear, a vamp 20, a sewing mainly is installed in 30 of vamp 20 inner surfaces on sole 10 inside, makes it to constitute one and can supply the space of foot's dress, and said vamp 20 mainly is made up of upper of a shoe sheet thermocompression forming.

Please cooperate Fig. 2, Fig. 3 and shown in Figure 4, this upper of a shoe sheet is compound and constitute by plastic 203 of substrate layer 201, interfacial agents 202, heat; This substrate layer 201 has the shoe head part 2011 that can thermocompression forming goes out the footwear boots, and the structural system of substrate layer 201 behind thermocompression forming vamp 20 appearance and modelings that concern, yet; Substrate layer 201 mostly is to adopt structural not good leatheret; For improving this substrate layer 201 easily in shoe head part 2011 collapse-deformations, it must be coated with last layer interface agent 202 at shoe head part 2011 inner surfaces, so that plastic 203 of deadlocked heat; Behind thermocompression forming, plastic 203 inner support framework that can form shoe head part 2011 of this heat.

Generally speaking; Plastic 203 of this heat must cut out reservation shape earlier; With chipping edger plastic 203 periphery of this heat formed fillet surface 2031 then, make plastic 203 of this heat behind applying substrate layer 201, this fillet surface 2031 can not be formed with lofty bad sense of touch at the handing-over periphery.

Learn that by above-mentioned explanation it is to be overcome that this upper of a shoe sheet truly has following problem to have in the reality use:

The first, heat plastic 203 mostly adopt PA class material, its thermocompression forming temperature up to 120 ℃ about; So under the high temperature; The out-of-flatness flaw phenomenon that causes substrate layer 201 outer surfaces very easily to produce can't expecting, so that obviously problem on the high side of fraction defective can occur processing, not only reduce production efficiency; And it is for the very big loss of dealer that material cost, time cost detract meaninglessly, makes the dealer extremely perplex.

Second; Plastic 203 thickness T 1 ≧ substrate layer thickness t 1 of its heat, otherwise the operator can't carry out the chamfered edge operation with what palm gripped, thus; Plastic 203 thickness T 1 of heat can't significantly be reduced; Cause the thermocompression forming time to reduce, and under high-temperature molding reciprocal effect, will make substrate layer 201 outer surface out-of-flatness flaw phenomenons even more serious.

The 3rd; Its substrate layer 201 must be coated interfacial agents 202 in advance; Plastic 203 of heat then need through cut, the chamfered edge operation could see through interface agent 202 and fit on the substrate layer 201, its processing procedure is quite complicated, the operating efficiency of integral body completion also can't promote; The more difficult growth of putting forward economic benefit, this is that present process technology can't break through part.

Further, hot plastic layer thickness ≦ 1/2 substrate layer thickness.

Further, substrate layer further has the shoe head part that the ability thermocompression forming goes out the footwear boots, the supporting framework of the moldable formation shoe head part of said heat.

Further, hot plastic layer periphery form can with the smooth-going fillet surface that joins of substrate layer inner surface.

Further, hot plastic layer select for use can softening flow at 70 ℃-90 ℃, the hot melt viscosity is between 4000-8000PS/150 ℃ TPU resinoid.

Further, to have hardness be that 97A, melt index are that 15-20g/10 ㎝ (2.16 ㎏/150 ℃), hardening time are the 30-90 rerum natura of second to hot plastic layer.

After adopting such scheme; The utility model makes it after being incorporated into the substrate layer inner surface by hot plastic layer material of control and thickness, and the hot-forming temperature of this substrate layer and hot plastic layer can be filled part and is reduced to 70 ℃; The hot-forming time then can be shorter; It is minimum that the out-of-flatness flaw phenomenon of substrate layer outer surface is reduced to, so have the yields height, structural good essence effect is promoted, and this hot plastic layer after hot-forming still has good hardness and elasticity.

On the other hand; The utility model is further to simplify the setting of commonly using the interface agent; And make the resinoid hot plastic layer of TPU directly hot melt coat the substrate layer inner surface, this kind improvement can simplify commonly use cut, chamfered edge and bonding process, and mode is for it automatically; Naturally it is more convenient fast to commonly use multiple operation, and production efficiency is improved.
