Highly wear-resistant biodegradable material for mobile phone shell and preparation method thereof

Abstract

The invention discloses a highly wear-resistant biodegradable material for a mobile phone shell. The highly wear-resistant biodegradablematerial comprises the following raw materials in parts by weight: 10-20 parts of straw, 50-70 parts of polylactic acid, 0.5-3 parts of a titanate coupling agent, 3-10 parts of a wear-resistant additive, 3-10 parts of a flame retardant, 3-10 parts of an antibacterial agent, and 1-4 parts of graphene. A preparation method comprises the following steps: washing, oven-drying and crushing the straw; adding the wear-resistant additive, the flame retardant, and theantibacterial agent to the treated straw short fibers for stirring and mixing treatment; then adding the titanate coupling agent for coupling treatment; and adding polylactic acid and graphene to thecoupling treated material, sending the mixture into a mixing stirrer for blending and kneading, and directly producing the highly wear-resistant biodegradable material after the kneading treatment iscompleted. The product can be automatically degraded under natural conditions, the product is environmentallyfriendly, safe, and non-toxic, and has good wear resistance, softness, antistatic ability and antibacterial ability, and all performance indicators reach national standards.

Problems solved by technology

[0004] However, the mobile phone case may contain toxic and harmful substances. Once these substances enter the human body, they cannot be excreted through normal metabolism and will cause great harm to the body.

Moreover, most of the mobile phone shells are made of non-degradable plastics. Due to the large demand and frequent replacement speed, there is a huge amount of waste plastic products in the environment, which has caused serious pollution to the environment; at the same time, the current mobile phones The anti-static ability and wear resistance of the shell are poor, and it does not have antibacterial function, which has a certain negative impact on the daily use of mobile phones
