The invention relates to a biodegradable fly-attracting sphere, which consists of the following components in weight percentage: 67% of a composite biodegradable material, 3% of a degradable color masterbatch, and 30% of a filler.
The composite biodegradable material is polylactic acid or polybutylene adipate terephthalate.
A preparation process of the biodegradable fly-attracting sphere includes the following steps: mixing the components measured by weight percentage uniformly and performing twin-screw granulation to obtain a composite biodegradable material; then placing the obtained composite biodegradable material in an injection molding machine for injection molding or in an extrusion blow molding machine for melt plasticization, and performing extrusion and inflation to form spheres; finally, riveting the injection-molded spheres or deflashing the blow-molded spheres to obtain the fly-attracting spheres.
The biodegradable fly-attracting sphere of the invention not only has fly-attracting performance, but also is biodegradable in the natural environment after being discarded, eliminating the environmental pollution caused by disposable non-degradable materials.
