[ detailed description ] of the invention
In order to better understand the technical scheme of the present invention, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 4, the method for producing an environment-friendly shoe material of the present invention comprises:
s1, recycling TPEE leftover materials generated in the processing process; because the TPEE formed sheet material can generate TPEE leftover materials when specifically processed into products such as soles, the TPEE leftover materials generated in the processing process need to be recycled in order to recycle the TPEE leftover materials and avoid pollution caused by the TPEE leftover materials.
S2, cutting the recycled TPEE leftover materials into blocky particles, wherein the length of the blocky particles is 2cm-3cm, the width of the blocky particles is 1cm-2cm, and the height of the blocky particles is 1cm-2cm.
Because the invention cuts the TPEE leftover into the block-shaped particles, and then uses the steam forming die 100 to directly and thermally press the block-shaped particles into the shoe material 200, the specification of the block-shaped particles has high requirements, because if the size of the block-shaped particles is too large, the block-shaped particles expand when forming in the steam forming die 100, the formed shoe material 200 is not easy to cool, the whole production time can be prolonged, and the formed shoe material can have holes; if the size of the block particles is too small, the supporting effect of the block particles in the steam forming mold 100 is not good, and the relative density of the formed shoe material 200 is too high, thereby resulting in a hard formed shoe material. Therefore, in the step S2 of the invention, the length of the block particles is 2cm-3cm, the width is 1cm-2cm, and the height is 1cm-2cm, and by adopting the block particles with the specification, the formed shoe material is easy to cool, the production time is reduced, the production efficiency is improved, holes can not appear in the formed shoe material, the relative density of the shoe material is moderate, the hard condition of the shoe material can not appear, and the quality of the formed shoe material can be ensured.
And S3, heating and forming the cut blocky particles by using a steam forming die, so as to obtain the shoe material. The step S3 specifically comprises the following steps:
filling the cut blocky particles into the shoe material cavity 103 of the steam forming die 100, controlling the steam forming die 100 to be matched, directly introducing steam into the shoe material cavity 103 of the steam forming die 100 for heating, and bonding the blocky particles in the shoe material cavity 103 to form a shoe material, wherein the shoe material 200 is a sole, an insole or a sheet. In the embodiment of the invention, before filling the cut block particles into the shoe material cavity 103 of the steam forming mold 100, the invention further comprises weighing the cut block particles according to the required weight of the shoe material, and filling the weighed block particles into the shoe material cavity 103 of the steam forming mold, so as to ensure that the formed shoe material is not lighter or heavier.
In order to realize the direct recycling of the TPEE leftover materials, the invention firstly proposes to fill the recycled TPEE leftover materials into the shoe material cavity 103 of the steam forming die 100 and directly utilize steam for heating forming; in order to realize direct steam heating forming of TPEE leftover materials, the invention has strict requirements on steam forming pressure, steam temperature and steam heating time; if the steam forming pressure is larger, the blocky particles are melted, and if the steam forming pressure is smaller, the bonding effect among the blocky particles is poorer; if the temperature of the steam is larger, the blocky particles are melted, and if the temperature of the steam is smaller, the bonding effect among the blocky particles is poorer; if the heating time of the steam is too long, the steam is wasted and the production efficiency is not advantageously improved, whereas if the heating time of the steam is too short, the adhesion effect between the lump particles is poor. Therefore, in the present invention, when the steam forming mold 100 heats and forms the block-shaped particles, the steam forming pressure is 1.97MPA-2.03MPA, the steam temperature is 195-255 ℃, and the steam heating time is 430S-530S, by adopting the above steam parameters, the block-shaped particles can be ensured not to be melted, and the block-shaped particles can be reliably bonded together, so that the formed shoe material 200 can not be broken in the use process, and the performance of the produced shoe material can be close to the level of the original TPEE; preferably, when the steam forming die 100 performs the heat forming of the block-shaped particles, the pressure of the steam forming is 2.00MPA, the heating time of the steam is 480S, and the temperature of the steam is 225 ℃.
The steam forming mold 100 comprises an upper mold 101 and a lower mold 102, and a shoe material cavity 103 is formed between the upper mold 101 and the lower mold 102 when the molds are closed; air holes (not shown) are uniformly distributed on the cavity wall of the shoe material cavity 103, and each air hole is communicated with a steam generating device (not shown) through an air pipe, so that when the shoe material cavity 103 is in operation, the steam generating device can directly introduce steam into the shoe material cavity 103, and therefore the block-shaped particles filled in the shoe material cavity 103 are heated and molded; in the specific implementation of the invention, the cavity wall of the shoe material cavity is fully distributed with air holes, and each air hole is uniformly distributed on the cavity wall of the shoe material cavity, so that each position of the shoe material cavity 103 can be uniformly heated, thereby uniformly heating the block particles in the shoe material cavity 103 and ensuring that adjacent block particles can be reliably bonded together.
In the implementation of the present invention, the method further includes step S4, after the shoe material 200 is formed, the steam is turned off, and the formed shoe material 200 is cooled for 240S-320S. When the cooling is specifically carried out, if the cooling time is short, massive particles can expand, and the shaping effect is poor; if the cooling time is too long, the production time is prolonged, which is not beneficial to improving the production efficiency; according to the invention, the cooling time is 240S-320S, so that the formed massive particles can be ensured not to have poor shaping effect due to expansion, and the production efficiency is improved. In addition, when cooling the molded shoe material 200, cooling water may be introduced into the shoe material cavity 103 of the steam molding die 100 after the steam is turned off to cool and shape the shoe material.
By adopting the technical scheme provided by the invention, the method has at least the following beneficial effects:
1. the recycled TPEE leftover materials are cut into the massive particles with specific specifications, the massive particles are filled into the shoe material cavity of the steam forming die, and steam is introduced into the shoe material cavity of the steam forming die to directly heat and form the TPEE leftover materials, so that the TPEE leftover materials generated in the actual production process are not required to be discarded, the waste of resources is avoided, the pollution to the environment can be reduced, and the environmental protection performance is good.
2. The length of the block particles is 2cm-3cm, the width is 1cm-2cm, and the height is 1cm-2cm, so that the formed shoe material is easy to cool, the production time is reduced, the production efficiency is improved, holes cannot be formed in the formed shoe material, the relative density of the shoe material is moderate, the hard condition of the shoe material cannot occur, and the quality of the formed shoe material can be ensured.
3. The method has the advantages that 100% of TPEE leftover materials can be directly used for producing shoe materials, the performance of the produced shoe materials can be close to the level of the original TPEE, the quality of the formed shoe materials can be ensured, and the adjacent TPEE leftover materials are reliably bonded together in the forming process mainly by controlling the parameters of steam without using adhesives such as AB glue materials, so that the waste of the adhesives can be reduced, and the shoe materials are more environment-friendly.
