Shoe with composite insole board and composite insole board manufacturing method

Abstract

The invention relates to a shoe with a composite insole board and a composite insole board manufacturing method; the composite insole board is arranged on a sole, and the composite insole board is molded by a dilute styrene-acrylic resin contained non-woven fabric and a reticulated styrene-acrylic resin membrane layer pasted on the upper surface of the non-woven fabric and a plane styrene-acrylic resin membrane layer pasted on the lower surface of the non-woven fabric; the composite insole board manufacturing method is that: clear water and dilute styrene-acrylic resin with only 12-25 percent of concentration are prepared in a material immersion barrel, and multiple groups of 50-200 DEG C of polished-surface rolling wheels are adopted for extrusion, so as to form the dilute styrene-acrylic resin contained non-woven fabric, and then 100 percent of the styrene-acrylic resin is coated on the upper and lower surfaces of the dilute styrene-acrylic resin contained non-woven fabric, drying is carried out by a drying oven, so as to form the plane styrene-acrylic resin membrane; a conical lattice shaped metal rolling wheel is used to lead the upper surface to form the reticulated styrene-acrylic resin membrane; as the adhesive performance is strong, the insole board is hard to deform, and the air permeability is greatly improved by the reticulate structure.

Description

technical field [0001] The invention relates to a shoe with a composite midsole and a method for manufacturing the composite midsole, especially for shoes such as leather shoes, sandals, sports shoes and travel shoes, and a method for manufacturing the composite midsole. Background technique [0002] At present, most of the midsole boards on the soles are made of glued pulp boards. Although they have a certain degree of air permeability, they still cannot meet the requirements of people's feet in shoes for ventilation, especially because the glued pulp boards themselves are sticky. The bonding strength is poor, and it is easy to deform when it is damp. Therefore, the adhesive pulp board is affected by the moisture of the human foot in the shoe, and often deforms and does not conform to the size of the sole of the foot, making the human foot feel uncomfortable. At the same time, the pulp board is easily corroded after being damp. However, it is broken and has a poor service l...

[0002] At present, most of the midsole boards on the soles are made of glued pulp boards. Although they have a certain degree of air permeability, they still cannot meet the requirements of people's feet in shoes for ventilation, especially because the glued pulp boards themselves are sticky. The bonding strength is poor, and it is easy to deform when it is damp. Therefore, the adhesive pulp board is affected by the moisture of the human foot in the shoe, and often deforms and does not conform to the size of the sole of the foot, making the human foot feel uncomfortable. At the same time, the pulp board is easily corroded after being damp. However, it is broken and has a poor service life; in recent years, there have been midsole panels that use non-woven fabrics containing glue. Because the non-woven fabrics are soaked in a large amount of styrene-acrylic resin glue, the bonding strength is greatly improved, and it is not easy to deform when exposed to moisture. It is also not easy to corrode, but still has poor air permeability, and the whole non-woven fabric is evenly soaked with a large amount of styrene-acrylic resin, which not only consumes a lot of styrene-acrylic resin glue, but also is not easy to shape on the sole
