Description
Technical field
The present invention relates to technical field of material, the degradable PLA biomaterial of specially a kind of suction pipe manufacture and
Preparation method.
Background technique
Polylactic acid (PLA) is a kind of biodegradable polyester material.The material acid of synthesizing polylactic acid is from jade
The natural crops such as rice, product can be degraded into water and carbon dioxide in the natural environment after discarded, therefore polylactic acid has life
Object degradability, recyclability, furthermore its good biocompatibility, good mechanical performance.But also having property is crisp for polylactic acid, impact strength
Low disadvantage.The toughness for improving polylactic acid can widen the application field of polylactic acid.Polylactic acid PLA be it is a kind of it is nontoxic can biology completely
The novel high polymer material of degradation, with the improvement of synthesis technology in recent years, it is production-scale expand, the decline of cost and
The rise of oil price, polylactic acid are going into more general plastics market extensively, partially instead of polyethylene, polyester and poly-
The plastics such as styrene alleviate conventional plastic pollution on the environment, it is therefore contemplated that it leads in high molecular material Related product
The application in domain will be fast-developing.
Polyethylene (polyethylene, abbreviation PE) is a kind of aggregated thermoplastic resin obtained of ethylene.Industrially,
It also include the copolymer of ethylene and a small amount of alpha-olefin.Polyethylene is odorless, nontoxic, feel ceraceous, has excellent resistance to low temperature,
Chemical stability is good, is resistant to the erosion of most of soda acids (intolerant to the acid with oxidizing property).Common solvent is not dissolved under room temperature,
Water imbibition is small, and electrical insulating property is excellent.
At present since not only property is crisp for polylactic acid (PLA), but also shock resistance is also low, therefore existing using polylactic acid
(PLA) its performance of suction pipe made of is all poor, significantly limits its popularization and application.For this purpose, the invention proposes a kind of suctions
Degradable PLA biomaterial of pipe manufacture and preparation method thereof.
