Abstract
The invention discloses a plastic cup and a processing method thereof, belonging to the technical field of a plastic product. The plastic cup consists of the following raw materials in parts by weight: 50-65 parts of polylactic acid, 10-18 parts of polycarbonate butanediol, 8-14 parts of polypropylene, 5-12 parts of chitosan fiber, 7-15 parts of sweet potato starch, 5-10 parts of light calcium carbonate, 3-9 parts of wollastonite, 2-5 parts of zinc oxide, 2-5 parts of aluminum hydroxide, 1-4 parts of stearic acid and 0-3 parts of a foaming agent. Polylactic acid and polycarbonate butanediol are taken as the main raw materials of the plastic cup disclosed by the invention; the plastic cup is characterized by easiness in degradation; the light calcium carbonate, wollastonite, zinc oxide and aluminum hydroxide are added for improving the strength and toughness of the plastic cup; the raw materials of the plastic cup are easily available, pure natural, safe and environmentally friendly; the preparation method is simple, the raw material cost is low and the requirement for mechanical equipment is low; the plastic cup is easy for large-scale popularization and application and has excellent economic benefits.
Description
Technical field [0001] The invention belongs to the field of plastic product processing, and specifically relates to a plastic cup and a processing method thereof. Background technique [0002] Plastic cup is a kind of container that is used in large quantities, especially for making milk tea, space cup, etc. At present, most of the plastic cups on the market are made of polyethylene, polypropylene and other polymer materials, which have poor heat resistance. Preheating will leach harmful substances, which are harmful to the body, and cannot be degraded, causing damage to the ecological environment and causing white pollution. Main source. [0003] With the enhancement of people's awareness of environmental protection and health preservation, consumers are increasingly demanding the quality of plastic cups. In order to implement the scientific development concept and build a resource-saving and environment-friendly society, people have begun to take effective measures from the so...
