Description

Regeneration EVA sole with physique training function

Technical Field

The utility model relates to a correct waist support shoes, in particular to regeneration EVA sole with physique training function belongs to rubber and plastic engineering technical field.

Background

Ethylene-vinyl acetate copolymer, EVA for short, because of introducing vinyl acetate monomer in the molecular chain, thus has reduced the high degree of crystallinity, has improved toughness, impact resistance, filler intermiscibility and heat sealability, is used in fields such as foamed shoe material, functional shed membrane, packaging mould, hot melt adhesive, wire and cable, car sealing element, daily plastic products and toys, etc. The shoe material is the most main application field of the EVA resin in China. Because the EVA resin blended foaming product has the performances of softness, good elasticity, chemical corrosion resistance and the like, the EVA resin blended foaming product is widely applied to soles and interior materials of medium and high-grade travel shoes, climbing shoes, slippers and sandals. In addition, the material is also used in the fields of sound insulation boards, gymnastic mats and sealing materials, and the EVA resin is widely applied in the fields of printing ink, cases, wine bottle mat covers and the like. Ethylene-vinyl acetate copolymer, one of the members of the major family of plastics, inevitably produces waste in the mass production and practical processes after being widely used, and how to recycle the waste and use the same grade as the virgin resin in the field of plastic products is a social environmental problem and also a major subject of the plastic recycling industry.

The body training shoes are called orthopedic shoes or correcting shoes, the history is sourced from Europe hundreds of years ago, the orthopedic shoes belong to the field of foot departments, and the foot departments in Europe, America and other foreign countries are independent departments compared with orthopedics, endocrinology, joint surgery and the like. A shape training shoe (orthopedic shoe or corrective shoe) is a special shoe for correcting foot diseases, which is manufactured for the purpose of correcting foot deformation, dispersing foot pressure, relieving pain symptoms, and the like, and may also be called a shoe shape orthosis.

Disclosure of Invention

In order to solve the technical problem that the EVA regeneration link can make further extensive and furthest substitute the virgin resin of product, the utility model provides a regeneration EVA sole with physique training function.

The utility model adopts the technical proposal that: a regenerative EVA sole with body training function, it is made up of sole body, side, paste the edge, bonding surface and bottom surface, the sole body is the light structure of the high back low high foaming rate and left and right feet that bend into the symmetry along with the left and right foot curve of human body, the side is that the peripheral edge extending upwards and connecting the bright and clean external decorative edge outside the sole body by the sole body, the medial surface of the upper end of side is a bonding edge and the upper surface of the sole body is a bonding surface; the sole body, the side edges, the sticking edges and the sticking surfaces are formed into an integral structure by one-time injection molding of regenerated EVA materials according to a mold, the bottom surface is of a structure comprising rubber and beef tendon, the lower surface of the bottom surface is an anti-slip surface comprising transverse and longitudinal strips and grains, and the upper surface of the bottom surface is a smooth surface and is stuck to the lower surface of the sole body.

The utility model has the advantages that: through the sole major structure that the sole body that adopts high foaming light weight structure constitutes, when effectively lightening sole weight and reaching and let the person of just practicing effectively alleviate the tired effect of feeling of foot, because of adopting the wear-resisting bottom surface of antiskid including rubber matter or the ox muscle matter, let the anti-skidding function and the wear-resisting function of sole effectively strengthen, and the side, paste limit and bonding face then according to the high density smooth and clean face that the mould formed decorative effect and pasted the function, let the sole do not glue with being connected of vamp more firmly.

Drawings

The present invention will be further explained with reference to the accompanying drawings:

fig. 1 is a schematic side sectional structure of the present invention.

In the figure, the sole comprises a sole body 1, a side edge 2, a side edge 3, a sticking edge 4, a sticking surface 5 and a bottom surface.

Detailed Description

In the embodiment of fig. 1, a regenerative EVA shoe sole with a body training function is composed of a shoe sole body 1, side edges 2, an adhesive edge 3, an adhesive surface 4 and a bottom surface 5, wherein the shoe sole body 1 is a lightweight structure with high front and low back foaming rates and is composed of left and right feet which are bent symmetrically along curves of left and right feet of a human body, the side edges 2 are outer decorative edges of a smooth surface which extends upwards from the outer peripheral edge of the lower surface of the shoe sole body 1 and is connected to the outer edge of the shoe sole body 1, the inner side surfaces of the upper ends of the side edges 2 are the adhesive edge 3, and the upper surface of the shoe sole body 1 is the adhesive; the sole body 1, the side edge 2, the sticking edge 3 and the sticking surface 4 are formed into an integral structure by one-time injection molding of regenerated EVA materials according to a mold, the bottom surface 5 is a structure comprising rubber and beef tendon, and an anti-slip surface comprising transverse and longitudinal strips and textures is arranged below the bottom surface 5, and the upper surface of the bottom surface 5 is a smooth surface and is stuck below the sole body 1.

Example 1: the regenerated EVA material is composed of a mixture composed of a primary EVA material and a foamed EVA waste material containing dead materials, active oil and a promoter TMTD, the mixture is composed of a target structure according to the structural requirements of the high-foaming light product on the primary EVA material, the component with the highest content proportion in the effective components of the EVA waste material is used as a conversion base number, the corresponding component proportion in the target structure is calculated, and then the mixture of the primary material and the waste material is obtained after the shortage of the component with the corresponding target structure of the waste material is supplemented and added.

Example 2: the utility model discloses a regenerated EVA material is for including mixture 98.6%, active oil 1.1%, promoter TMTD 0.3%'s material structure according to weight percentage, and this material is refined after the closed micelle that smelts into of mill through the closed mill, refines after the mill mixes the micelle into 1 millimeter and following film thickness with the micelle again, and the back roller diameter of the purpose-made mill of refining usefulness is 610mm, and preceding roller diameter is 480mm, and the back roller is 1 with the rotational speed ratio of preceding roller: 1.82, the rotation speed of a front roller is 50 revolutions per minute, the refining temperature is 148-152 ℃, sheets are produced at the thickness of 30 silk meters or less, and then the injectable granules are prepared by a granulator.

Example 3: firstly, erecting a pre-designed and prepared mould on an injection molding machine, then injecting EVA granules prepared according to the physical index requirement of the high-foaming-rate light structure into the injection molding machine, and finally performing regenerative EVA injection molding on the sole for shape training.
