In order to technical scheme is explained further, below by specific embodiment, the present invention will be described in detail.
Refer to shown in Fig. 1 to Fig. 5, for the first embodiment of the forming method of thermoplastic composite material of the present invention, it is pointed out that the forming method of this thermoplastic composite material comprises the following steps:
A one thermoplastic film 10 and a cloth material 20 are cut into predetermined shape by (), and this thermoplastic film 10 is less than this cloth material 20.This thermoplastic film 10 is polymerized material with thermoplasticity, the batch that coloring agent is constituted, through being made up of extruder after mixing, it can be plastic polyurethane elastomer resin (TPU)+stilbene-butene rubber (SBR), or plastic polyurethane elastomer resin (TPU)+styrene (SEBS), or plastic polyurethane elastomer resin (TPU)+thermoplastic rubber (TPR), or plastic polyurethane elastomer resin (TPU)+lactoprene (EPDM), or plastic polyurethane elastomer resin (TPU)+TPU PUR, or the either of which of plastic polyurethane elastomer resin (TPU)+nylon elastomer.The color of this thermoplastic film 10 can be formed with the either of which of mode of printing, coating color film mode or surface sandwich like way.The thickness of this thermoplastic film 10 is about 0.05~2.5mm, and it is formed (as shown in Figure 2) by a surface layer 11 and a laminating layer 12, and the fusing point of this surface layer 11 relatively this laminating layer 1 is high, the temperature difference of both fusing points more than about 5 DEG C.This cloth material 20 can be flat fabric, looped fabric, adhesive-bonded fabric or Sandwich screen-cloth etc..
B this thermoplastic film 10 is arranged in the end face of the microscope carrier 30 of a forming machine and makes its laminating layer 12 upward by (), then make it cover this thermoplastic film 10(as shown in Figure 3 the upper side that this cloth material 20 stacking is arranged in this thermoplastic film 10).Having plural air flow channel 31 in this microscope carrier 30, the end face in this microscope carrier 30 is provided with plural number concave convex texture 32 and plural number minute aperture 33, and this plural number concave convex texture 32 can be same decorative pattern or can be several different decorative patterns.The aperture of this plural number minute aperture 33 is about 0.001mm, and it is laid in the end face of this microscope carrier 30 uniformly and penetrates into this plural number air flow channel 31 respectively.
C () utilizes a heating unit 40 to heat this thermoplastic film 10, make this laminating layer 12 form hot melt state and make this surface layer 11 slightly soften.Extract the air in this plural number air flow channel 31 by a vacuum unit 34 simultaneously and make a pressing part 50 be pressed on the end face of this cloth material 20.This pressing part 50 comprises gas barrier film 51 and a pressing mold 52, the fusing point of this gas barrier film 51 is higher than this surface layer 11, its material can be rubber or silicone etc., and this gas barrier film 51 covers the upper side of this microscope carrier 30 and this cloth material 20, and this pressing mold 52 can be pressed on the upper side of this gas barrier film 51.
So, when this vacuum unit 34 carries out evacuation, the negative pressure state of subatmospheric power will be formed between end face and this gas barrier film 51 of this microscope carrier 30, this negative pressure state is utilized to be adsorbed downwards by this gas barrier film 51, so that this gas barrier film 51 is by the applying pressure down over of this cloth material 20, add this pressing mold 52 simultaneously and be downwardly applied to gravity by the upside of this gas barrier film 51, the laminating layer 12 of this thermoplastic film 10 just can be made to penetrate in this cloth material 20 and form laminating closely.Especially, this thermoplastic film 10 can be adsorbed downwards with this cloth material 20 by this plural number minute aperture 33, the surface layer 11 of this thermoplastic film 10 so can be made should the three-dimensional pattern relatively sharp and obvious (as shown in Figure 5) that formed of the concave convex texture 32 of microscope carrier 30.And, utilize the thermoplastic composite material made by the forming method of the present embodiment, can be directly made up of with thermoplastic film 10 various difform cloth materials 20 especially, therefore it can have more structure change, and it can by difform design, and can be applicable to make shoes, suitcase, medicated cap etc. especially.
In this first embodiment, this pressing part 50, in addition to can comprising gas barrier film 51 and pressing mold 52, can also be only this gas barrier film 51 or the one of which of this pressing mold 52 simultaneously.Such as, gas barrier film 51 the most just can only be used when the cloth gap of cloth material 20 is big.And, this heating unit 40 can be located among this microscope carrier 30 or this pressing mold 52.
Refer to shown in Fig. 6, Fig. 7, for the second embodiment of the present invention, it is pointed out that the forming method of this thermoplastic composite material comprises the following steps:
A one thermoplastic film 10 and a cloth material 20 are cut into predetermined shape by (), the structure of this thermoplastic film 10 and cloth material 20 is same as first embodiment.
B this cloth material 20 is arranged in the end face of the microscope carrier 30 of a forming machine by (), then by the laminating layer 12 of this thermoplastic film 10 upper side being stacked and placed on this cloth material 20 down.Having plural air flow channel 31 in this microscope carrier 30, the end face in this microscope carrier 30 is uniformly laid with the plural minute aperture 33 penetrating into this air flow channel 31.
C () utilizes a heating unit 40 to be heated to this thermoplastic film 10 making this laminating layer 12 form hot melt state, extract the air in this plural number air flow channel 31 by a vacuum unit 34 simultaneously and make a pressing part 50 be pressed on the end face of this thermoplastic film 10.
So, when this vacuum unit 34 carries out evacuation, the negative pressure state of subatmospheric power will be formed between end face and this gas barrier film 51 of this microscope carrier 30, this negative pressure state is utilized to be adsorbed downwards by this gas barrier film 51, so that this gas barrier film 51 is by the applying pressure down over of this thermoplastic film 10, add this pressing mold 52 simultaneously and be downwardly applied to gravity by the upside of this gas barrier film 51, and utilize this plural number minute aperture 33 to pass through the effect that this thermoplastic film 10 is adsorbed downwards by this cloth material 20, just the laminating layer 12 that can make this thermoplastic film 10 penetrates into and forms laminating closely in this cloth material 20.And, utilize the thermoplastic composite material made by the forming method of the present embodiment, can be directly made up of with thermoplastic film 10 various difform cloth materials 20 especially, therefore it can have more structure change, and it can by difform design, and can be applicable to make shoes, suitcase, medicated cap etc. especially.
In this second embodiment, this pressing part 50, in addition to can comprising gas barrier film 51 and pressing mold 52, can also be only this gas barrier film 51 or the one of which of this pressing mold 52 simultaneously.Such as, gas barrier film 51 the most just can only be used when the cloth gap of cloth material 20 is big.And, this heating unit 40 can be located among this microscope carrier 30 or this pressing mold 52.
Above-described embodiment and the product form of the graphic and non-limiting present invention and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as the patent category without departing from the present invention.
