Benefits of technology

This patented technology provides an improved way for making plastic that breaks down naturally over time without harming their environment or causing damage during disposal. It uses special materials made from natural sources like silica sand particles instead of synthetic ones such as polymers (plants). These new products will break up quickly into small pieces which become less dangerous than traditional plasties due to better properties they don't contain chemicals used inside them.

Problems solved by technology

This patented technical solution describes how to create strong yet easily decomposible or recyclizable plastic products made entirely out of renewables like natural rubber. These new plastisolymers have excellent properties for various applications including medical devices, electronics, automobiles, shoe manufacturing, bag making, waste management, and other industries where they replace conventional plastsynzies due to their low prices and potential negative impact on our planet over time. Plaste disposals currently pose challenges because there may still exist some small amounts of organically filled resin residue left behind during landfill operations. To address these issues, an improved method called nanoplasmonium coating was developed based on biocide filling technology.

Abstract

The invention relates to an inorganic-filling material full-biodegradation composite material with high compatibility and a preparation method thereof, belonging to the technical field of high polymer materials. The inorganic-filling material full-biodegradation composite material is prepared from the following components by weight: 5 to 70 parts of an inorganic-filling material full-biodegradation master batch and 30 to 95 parts of biodegradable polyester. The inorganic-filling material full-biodegradation composite material provided by the invention is fully biodegradable, has good processing performance, presents a good dispersion effect in a biodegradable polyester matrix identical to a master batch carrier and shows good compatibility between the master batch and a polyester matrix when the master batch carrier and the biodegradable polyester matrix are not same polyester. Addition of the master batch into the biodegradable polyester enables preparation cost for a biodegradable polyester product to be substantially reduced.
