Problems solved by technology

Although this kind of material has an excellent effect on the lightweight of shoes, but because it is the result of foaming and then hardening molding, it has the disadvantage of insufficient softness, so that it is not comfortable enough to wear.

Embodiment Construction

[0019] The invention provides a method for manufacturing a combined midsole of shoes, especially using PU glue as an interface adhesive in a rough structure, so that EVA material and PU material are aggregated together, thereby producing an elastic, soft and light midsole. The method of the midsole of the shoe with unique characteristics, and can strengthen the elastic characteristic or lightness characteristic of the midsole of the shoe according to different manufacturing methods.

[0020] In order to enable a more in-depth and specific understanding of the manufacturing method of the present invention, the technical means, structural implementation and effects of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] First, as shown in Fig. 1, Fig. 3 and Fig. 4, the manufacturing method of the combined midsole of the present invention mainly includes: placing a prefabricated EVA material 11 in a...

Abstract

The invention discloses a making method of bottom of EVA and PU material in the built-up formula, which comprises the following steps: placing a preset EVA material in the mould; setting several course flutes on the material; coating PU glue in the flute; heating to 50-60 deg.c; pouring liquid PU material; heating to solidifying PU; stripping; obtaining the product.

Description

technical field [0001] The invention relates to a method for combining EVA (polyolefin plastic) and PU (polyurethane resin) to manufacture a combined midsole for shoes. Background technique [0002] In general shoes, the composition of the sole structure is directly related to whether the shoes are comfortable to wear. In order to meet the user's requirements for wearing comfort, most of the industry uses elastic PU materials to make midsoles. This method can indeed provide better touch and elasticity for the foot, but in terms of the adaptability of the human body structure, this kind of full elasticity does not necessarily meet the requirements of the foot. When the human foot is walking, only the heel and forefoot are subjected to a large stepping vibration force and striding movement, which requires better softness to provide better support protection, so it is completely made of PU material As for the design structure of the midsole, it causes the uncomfortable feelin...
