[0082] Table 1 Performance indicators of the biodegradable buttons of Examples 1 to 3 and Comparative Examples 1 to 2

[0083]

[0084]

[0085] Table 1 shows that the compressive strength of the biodegradable buttons obtained in Examples 1 to 3 is higher than that of the buttons in Comparative Examples 1 to 2.

[0086] Experimental Example 2

[0087] The biodegradable buttons of Examples 1 to 3 were buried in soil with a depth of 10 cm, and the degradation of the biodegradable buttons was observed under natural conditions after burial. The burial time was April 11th. When dug up on August 11th of the same year, the buttons in the soil had rotted, and there were still some buttons remaining that were not completely corroded. When the soil where the buttons were buried was dug up again on October 11th of the same year, the biodegradable buttons in it had completely rotted, and no residues were found. This shows that the biodegradable buttons of the present invention can be completely degraded within 6 months.

The button of the present invention uses corn straw and rice husk as raw materials, realizing the recycling of resources. Using glutinous rice flour, potato starch, walnut powder, and soy protein powder as fillers and adding them to the preparation of the buttons of the present application can make the buttons fuller and more shiny. The present invention uses butyl epoxy fatty acid ester and agar as binders, which can increase the mechanical properties of the buttons. The biodegradable buttons prepared according to the formula of the present invention can be completely degraded within 6 months.

[0089] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
