It is good, and fracture resistance is poor, is easily broken off when by bending external force effect.
The content of the invention：
The technical problem to be solved in the present invention is to provide a kind of preparation method of high anti-folding SBS composite sole materials, prepares
The material for sole of shoe gone out has good fracture resistance and heat resistance.
In order to solve the above technical problems, the technical scheme is that：
A kind of preparation method of high anti-folding SBS composite sole materials, its step are as follows：
(1) mesh polypropylene-fibre is dissolved in toluene, is placed in vibration in ultrasonator and removes mesh polypropylene-fibre table
The oil stain and impurity in face, take out and be washed with deionized water only after 2 hours, be placed in baking oven and dry 2 hours, move to plasma processing chamber
In, argon gas is passed through after vacuumizing and opens radio-frequency power supply progress plasma treatment, is taken out after 3 minutes, obtains modified polypropene net
Shape fiber is standby；
(2) SBS, MAH are dissolved in MEK, stirring is moved in constant temperature water bath to after being completely dissolved, and is led under nitrogen protection
BPO is added dropwise, reaction is evaporated under reduced pressure after 1 hour and removes MEK, and SBS, the MAH for not participating in reaction are removed with ketone extracting, is put
In vacuum drying chamber drying to constant weight, it is standby to obtain SBS-g-MAH；
(3) SBS-g-MAH for obtaining SBS, PTFE, step (2) adds high-speed mixer and mixing 10 minutes, is blended
Material, is stirred by ultrasonic to being uniformly dispersed after blend composition is mixed with acetone, obtains prepreg, the modification poly- third that step (1) is obtained
Alkene reticular fibre is soaked in prepreg, is taken out and is dried after 20 hours, is laid in mould after cutting, is molded with platen-press,
High anti-folding SBS composite sole materials are obtained after cooling and demolding.
Preferably, in step (1) of the present invention, the temperature of drying is 70 DEG C.
Preferably, in step (1) of the present invention, the discharge power of radio-frequency power supply is 80W.
Preferably, in step (2) of the present invention, SBS, MAH, BPO weight ratio are 100:40:3.
Preferably, in step (2) of the present invention, the temperature of constant temperature water bath is 82 DEG C.
Preferably, in step (2) of the present invention, dry temperature is 90 DEG C.
Preferably, in the step (3), by weight, SBS 52-63 parts, PTFE 10-14 parts, SBS-g-MAH 5-
6 parts, modified polypropene reticular fibre 25-30 parts.
Preferably, in step (3) of the present invention, the temperature of high mixer mixing is 120 DEG C.
Preferably, in step (3) of the present invention, the temperature of molding is 140 DEG C, and the pressure of molding is 1.2MPa.
Compared with prior art, the invention has the advantages that：
(1) mesh polypropylene-fibre be using modified polypropene as raw material, extruded, stretching, networking, surface treatment, be chopped
The netted organic fiber being process etc. process, it has very high tensile strength, by plasma treatment post plasma at it
Surface generates etching action, greatly increases the roughness on its surface, and generates many grooves and crackle, can significantly increase
Mechanical riveted effect between mesh polypropylene-fibre and SBS matrixes, improves adhesion strength therebetween, formed consistency compared with
High network structure, when composite sole material is by bending external force, mesh polypropylene-fibre can produce larger drawing-resistant function
Power, bending external force can consume substantial amounts of energy when fractureing or extracting mesh polypropylene-fibre so that SBS matrixes are subject to broken
It is bad to be reduced to minimum level, so as to substantially increase the fracture resistance of composite sole material.
(2) PTFE is that the English of polytetrafluoroethylene (PTFE) is write a Chinese character in simplified form, and the bond energy of its intramolecule C-F keys is very high, therefore with fine
Resistance to elevated temperatures, but its compatibility between SBS matrixes is bad, therefore the present invention has been made compatible by graft reaction
Compatibility between agent SBS-g-MAH, MAH maleic anhydride and PTFE is preferable, thus SBS-g-MAH can be effectively improved PTFE with
Compatibility between SBS matrixes simultaneously forms good interface cohesion, and then greatly improves the heat resistance of composite sole material；This
Outside, PTFE also has good corrosion resistance, weatherability and very low wearing coefficient, therefore can also effectively improve composite sole
Corrosion resistance, weatherability and the wearability of material.
