Embodiment 1

[0036] A modified bio-calcium carbonate rubber outsole in this embodiment consists of the following components in parts by mass:

[0037]

[0038] Wherein said solution polystyrene-butadiene rubber has Mooney viscosity ML (1+4) 60 (100 ℃); Comprise epoxy soybean oil 17%, styrene 33%; Vinyl 34%% (vinyl accounts for butadiene total The mass ratio of the amount); Nitrile rubber has a Mooney viscosity ML (1+4) 60 (100 ° C), and the combined acrylonitrile 42.5%; Eucommia rubber has a Mooney viscosity ML (1+4) of 40-75 at 100 ° C 4).

[0039] 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 is attached to the outside, and the preparation method is as follows:

[0040] ①Taking fresh mussels, kneading, cleaning, and extracting the shredded mussels to obtain the shredded mussels, and then separating the shell and meat to obta...

Embodiment 2

[0046] 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;

[0047]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 .

Embodiment 3

[0049] The difference between embodiment 3 and embodiment 1 is:

[0050] A modified bio-calcium carbonate rubber outsole in this embodiment consists of the following components in parts by mass:

[0051] 40 parts of nitrile rubber DN3350, 20 parts of solution-polymerized styrene-butadiene rubber, 25 parts of Eucommia rubber, 22 parts of bio-modified calcium carbonate, 2 parts of anti-aging agent BHT, 1.2 parts of stearic acid, 0.8 parts of polyethylene wax, 1.2 parts of carbon nine resin parts, 2.3 parts of insoluble sulfur, 0.9 parts of vulcanization accelerator NS, and 0.9 parts of vulcanization accelerator TBZTD-75.

[0052] Described solution polystyrene-butadiene rubber has Mooney viscosity ML (1+4) 55 (100 ℃); Comprise epoxy soybean oil 30%, styrene 25%%; Vinyl 38% (vinyl accounts for butadiene total amount mass ratio).

Abstract

The invention discloses a modified biological calcium carbonate rubber outsole and a preparation method thereof. The outsole comprises nitrile rubber, solution polymerized styrene-butadiene rubber, eucommia ulmoides rubber, modified biological calcium carbonate, an anti-aging agent, a lubricant, tackifying resin, insoluble sulfur and a vulcanization accelerator; and the modified biological calcium carbonate is biological calcium carbonate powder modified by mussel mucoprotein extract. According to the invention, mussels are fully utilized, biological raw materials are respectively 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 rubber outsole. Background technique [0002] Existing sole base materials include cowhide, rubber, PU, ​​EVA, TPU, PVC, ABS, PE, PP or SBR and the like. Among them, rubber is usually used for the outsole, because rubber is low in cost, elastic, and has good waterproof performance. However, the disadvantages of rubber are also obvious, that is, it is heavy, and its wear resistance and anti-skid performance cannot meet high requirements. [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 through the mussel mucin secreted by their pedic...
