Embodiment 1

[0082] figure 1 An example of the shoe midsole of the present invention is shown.

[0083] A shoe midsole made of CRB ceramics was fabricated as follows.

[0084] (Production of CRB ceramic front skeleton)

[0085] 75 kg of defatted rice bran obtained from rice bran and 25 kg of liquid phenolic resin (resol resin) were mixed and kneaded while being heated to 50 to 60°C. A homogeneous mixture with plasticity can be obtained.

[0086] The mixture was once fired at 900° C. for 60 minutes in a nitrogen atmosphere using a rotary furnace. Next, the obtained carbonized fired product was sieved through a 100-mesh sieve to obtain carbonized powder with a particle diameter of 50 to 250 μm.

[0087] 75 kg of the obtained carbonized powder and 25 kg of solid phenolic resin (resole resin) were mixed and kneaded while being heated to 100 to 150°C. Plastics of CRB ceramic pre-skeletons can be obtained as homogeneous mixtures with plasticity.

Embodiment 2

[0098] (Production of CRB ceramic front skeleton)

[0099] 75 kg of defatted rice bran obtained from rice bran and 25 kg of liquid phenolic resin (resol resin) were mixed and kneaded while being heated to 50 to 60°C. A homogeneous mixture with plasticity can be obtained.

[0100] The mixture was once fired at 900° C. for 60 minutes in a nitrogen atmosphere using a rotary furnace. Next, the obtained carbonized fired product was sieved through a 100-mesh sieve to obtain carbonized powder with a particle diameter of 50 to 250 μm.

[0101] 75 kg of the obtained carbonized powder and 25 kg of solid phenolic resin (resole resin) were mixed and kneaded while being heated to 100 to 150°C. The CRB ceramic pre-skeleton can be obtained as a homogeneous mixture with plasticity.

[0102] (Forming of shoe midsole)

[0103] Next, put Figure 4 The skeleton 1 ' of the foot-shaped plate-like body that shows hole 2 is made of aluminum is put into metal mould, and the plastic thing of skele...

Embodiment 3

[0108] (Manufacturing of the front skeleton of RB ceramics)

[0109] 75 kg of defatted rice bran obtained from rice bran and 25 kg of liquid phenolic resin (resol resin) were mixed and kneaded while being heated to 50 to 60°C. Plastics can be obtained as a homogeneous mixture of RB-ceramic pre-skeletons with plasticity.

[0110] (Forming of shoe midsole)

[0111] Next, put Figure 4 The skeleton 1 of the foot-shaped plate-shaped body with holes 2 made of the shown anodized aluminum is put into a metal mold, and the plastic of the front skeleton of the RB ceramic is pressurized with a pressure of 30Mpa. The temperature of the metal mold is 150°C.

[0112] Take out the molded body from the metal mold, raise the temperature to 500°C at a rate of 1°C / min in a nitrogen atmosphere, then heat at a rate of 2°C / min, and heat treat at 700°C for about 120 minutes. Next, it is naturally cooled to obtain a molded body.

Abstract

The invention provides a lightweight midsole with long service life, excellent wear resistance, air permeability and easy manufacture and shoes using the midsole. The shoe midsole is a skeleton of a foot-shaped plate-shaped body made of light metal, and a foot-shaped plate-shaped body formed of RB ceramics or CRB ceramics formed around the skeleton.

Description

technical field [0001] The present invention relates to a shoe midsole made of hi-tech eco-material (a cutting-edge technical material with excellent environmental adaptability) using biological resources different from conventional industrial materials, and a shoe using the shoe midsole. Background technique [0002] Most of the shoe midsoles in the past are made of animal leather or soft or hard rubber, polymer resin materials, but there are some problems in these materials. [0003] The conditions required for the midsole of the shoe are strong but light, wear-resistant, not affected by temperature, easy to manufacture and low in cost. [0004] None of the aforementioned various conventional materials can fully satisfy the above-mentioned required characteristics. [0005] For example, animal leather feels high-grade and is easy to adapt to the shape of the foot. It is a material with excellent softness, but it is easily affected by temperature and has poor wear resistan...
