Further with improvement, above-mentioned sole housing is TPU sole housings, and the thickness of sole housing is 1~5mm.
Further with improvement, it is provided with the side wall of above-mentioned sole housing and connects above-mentioned accommodating cavity and extraneous air-vent.
Further with improvement, above-mentioned isocyanic acid ester layer is located at the outside of above-mentioned polyether polyols alcohol layer；Between TPU expanded beads
Abutting edge polyether polyols alcohol layer and isocyanic acid ester layer mixed distribution.
Further with improvement, the thickness of above-mentioned polyether polyols alcohol layer is 10~200 microns, the thickness of above-mentioned isocyanic acid ester layer
For 3~60 microns.
The particle diameter of the TPU expanded beads after foaming is 1~6mm.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent
Point：Footwear material agent structure of the present utility model is more simple, by polyether polyols alcohol layer and isocyanic acid ester layer successively coated structure,
The usage amount of PPG and isocyanates can effectively be reduced so that TPU expanded beads are effective in the accounting of whole footwear material
Lifting, 90% or so limit proportion can be reached, the weight of footwear material is effectively reduced, and can embody ultralight, superelevation bullet
Performance characteristics, also cause footwear material the feature of environmental protection further lifted；The sole of the present utility model of the footwear material main body is configured, more
Light, gas permeability is strong, bradyseism performance is good, is also equipped with good massage effect.In addition, the TPU foaming of footwear material of the present utility model
Spherical Clearance structure between particle be present, footwear material possesses good ventilative, infiltration, perspiration discharging performance, and the bradyseism performance of footwear material obtains
Further lifting；In addition, the granular sensation on footwear material surface becomes apparent, in use, having to human foot contact site obvious
Massage effect and improve sanguimotor function.

Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Reference picture 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, light-weight environment-friendly puffed rice sole, including footwear material main body 1 and sole housing 2,
The fixing assembling of footwear material main body 1 is in the accommodating cavity 20 of the sole housing 2.The sole housing is preferably that TPU materials make, shoe sole shell
The thickness of body 2 is preferably 1~5mm；It is provided with the side wall of sole housing 2 and connects above-mentioned accommodating cavity 20 and extraneous air-vent
21.With continued reference to Fig. 2, Fig. 4, Fig. 5, footwear material main body 1 is made up of a plurality of TPU expanded beads 11 bonding, and TPU expanded beads 11 are in
Spherical or elliposoidal.Spherical Clearance 10 be present between adjacent above-mentioned TPU expanded beads 11.Above-mentioned TPU hairs after foaming
The particle diameter for steeping particle 11 is 1~6mm.The surface of the TPU expanded beads 11 is sequentially coated with polyether polyols alcohol layer 12 and isocyanic acid
Ester layer 13, isocyanic acid ester layer 13 are located at the outside of the polyether polyols alcohol layer 12；The thickness of above-mentioned polyether polyols alcohol layer 12 be 10~
200 microns, the thickness of above-mentioned isocyanic acid ester layer 13 is 3~60 microns.Abutting edge between TPU expanded beads 11 is molded in footwear material
During, polyether polyols alcohol layer 12 and isocyanic acid ester layer 13 are extruded and promote the mixing of the two and form adhesive layer 14, TPU
It is bonded as one between expanded beads 11 by the adhesive layer 14.Light-weight environment-friendly puffed rice footwear sole construction of the present utility model is more
Simply, by polyether polyols alcohol layer 12 and isocyanic acid ester layer 13 successively coated structure, PPG and different can effectively be reduced
The usage amount of cyanate so that TPU expanded beads 11 are effectively lifted in the accounting of whole footwear material, can reach 90% or so pole
Limit ratio, the weight of footwear material are effectively reduced, and can embody the performance characteristics of ultralight superelevation bullet, also cause footwear material
The feature of environmental protection is further lifted；In addition, Spherical Clearance structure, footwear be present between the TPU expanded beads 11 of footwear material of the present utility model
