Problems solved by technology

[0002] EVA is one of the commonly used base materials for soles. It is cheap and feels very soft and elastic when wearing shoes at the beginning. However, due to the strong memory of EVA, it is easy to cause poor cushioning performance due to repeated trampling after a long time. Hardening, this is because the air in the EVA material is squeezed out due to repeated trampling, so the performance is also greatly reduced

Embodiment 1

[0040] A kind of modified biological calcium carbonate EVA environmental protection sole of the present embodiment is made up of following components by mass parts:

[0041]

[0042]

[0043] The modified biological calcium carbonate is biological calcium carbonate powder modified by mussel mucin extract, the particle size of the biological calcium carbonate powder is 100-300 μm, and mussel mucin extract is attached to the outside, and the preparation method is as follows:

[0044] ①Taking fresh mussels, kneading, cleaning, and extracting the shredded mussels to obtain the shredded mussels, and then separating the shell and meat to obtain the mussel meat and mussel shells;

[0045] ②Dry the foot glands of mussel foot silk and mussel meat and grind them into powder, add them to 5% glacial acetic acid solution containing phenylmethylsulfonate fluoride, make a homogenate with a homogenizer at 0°C, and pass through Iced ethanol is extracted 2-3 times, and the supernatant is ...

Embodiment 2

[0053] The difference between embodiment 2 and embodiment 1 is: further extraction on the basis of step 1) crude extract solution to prepare fine extract solution;

[0054] Add twice the volume of acetone (-85°C) dropwise to the crude extract solution, let it stand for half an hour and then centrifuge, take the precipitate and dissolve it in 5% glacial acetic acid, and centrifuge again to get the supernatant, which is the fine extract solution .

[0055]

Embodiment 3

[0057] The difference between embodiment 3 and embodiment 1 is:

Abstract

The invention discloses a modified biological calcium carbonate EVA environment-friendly sole and a preparation method thereof. The sole comprises the following components of: EVA, a regenerated EVA film, an SEBS elastomer, modified biological calcium carbonate, a nucleating agent, a foaming agent, a cross-linking agent, zinc oxide, stearic acid, zinc stearate, a flowable agent, a foaming aid and a cross-linking aid. The modified biological calcium carbonate is biological calcium carbonate powder modified by mussel mucoprotein extract. According to the modified biological calcium carbonate EVA environment-friendly sole andthe preparation method thereof of the invention, mussels are fully utilized, biological raw materials are extracted from byssus or foot gland tissues and shells, and processed, and the performance of a common sole base material is improved.

Description

technical field [0001] The invention belongs to the technical field of shoe sole materials, and in particular relates to a preparation method of a modified biological calcium carbonate EVA environment-friendly shoe sole. Background technique [0002] EVA is one of the commonly used base materials for shoe soles. It is cheap and feels very soft and elastic when wearing shoes at the beginning. However, due to the strong memory of EVA, it is easy to cause poor cushioning performance due to repeated trampling after a long time. Hardening, this is because the air in the EVA material is squeezed out due to repeated trampling, so the performance is also greatly reduced. [0003] The common silk mollusks in China are mainly Heterocylindae species, involving Mytilidae, Clamidae, Pearl Oysteridae, Jiangyaoidae, Scallopidae and Varanidae. Few kinds. Molluscs with pedicles often fix themselves on solid surfaces such as rocks, ship hulls, cables, drifting bottles, etc. under the sea th...
