Process for producing plastic cups

Abstract

The invention relates to a process for producing plastic cups, and belongs to the field of technologies for manufacturing plastics. High-density polypropylene granules are used as base materials for the plastic cups, anti-aging agents, transparent agents, curing agents, ramie fibers and nanometer calcium carbonate are used as auxiliary materials for the plastic cups, and the high-density polypropylene granules which are used as the base materials are prepared from polypropylene, isopropyl alcohol, titanium carbide, nanometer silica gel, thermoplastic polyester elastomers, modified phenolic resin, calcium stearate, deionized water and antioxidants. The process for manufacturing the plastic cups includes steps of weighing raw materials; drying the raw materials; carrying out antibacterial treatment on fibers; mixing the raw materials with one another; carrying out injection molding; carrying out post-treatment. The process for producing the plastic cups has the advantages that procedures are simple and controllable, the process is low in cost and pollution, conforms to concepts of sustainable development and is worthy of being popularized, and the plastic cups produced by the aid of the process are high in mechanical strength and transparency, exquisite in texture and long in service life.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of plastic production and manufacturing, in particular to a production process of a plastic cup. [0003] 【Background technique】 [0004] Plastic cups are commonly used utensils for drinking water in people's lives. Based on their light texture, beautiful appearance, low cost and strong plasticity, they are deeply loved by people. [0005] Not only that, plastic cups also have the advantages of saving time and effort in processing and changing shapes, and have developed rapidly in recent years. However, the plastic cup products currently on the market have general transparency, poor toughness, short service life, complicated manufacturing process, and serious environmental pollution, which increases the cost. [0006] 【Content of invention】 [0007] Aiming at the defects existing in the prior art, the object of the present invention is to provide a production process of plastic cups. The plastic cu...
