Abstract
This invention discloses a PP material for plastic cups, belonging to the technical field of PP materials. It comprises the following raw materials in parts by weight: 70-80 parts copolymer polypropylene resin, 6-12 parts nano zinc oxide, 5-10 parts bamboo fiber, 3-6 parts antibacterial agent, 0.2-0.5 parts nucleating agent, and 0.6-1.8 parts auxiliary additives. This invention significantly enhances the antibacterial ability of the PP material by introducing a self-made antibacterial agent containing chloramine and chitosan antibacterial groups. The benzene ring in the antibacterial agent's molecular structure acts as a rigid group, helping to improve the overall heat resistance of the material, making it less prone to heat aging, softening, or deformation when containing high-temperature liquids. The use of natural and renewable materials such as bamboo fiber and chitosan enhances the product's environmental friendliness and safety. In summary, this invention provides a PP material that combines high-efficiency antibacterial properties, good heat resistance, and environmental friendliness, making it particularly suitable for manufacturing plastic cups.
