Highly antibacterial sanitary keycap material and preparation method thereof

The invention relates to the field of high polymer materials, in particular to a highly antibacterial and sanitary keycap material and a preparation method thereof, and is used for solving the problem that an existing keycap material is poor in antibacterial and sanitary performance. According to the preparation method, PBT resin and PP resin serve as main raw materials, after active substances are added into the main raw materials, the antibacterial and bacteriostatic performance and the hydrophobic effect of the key cap material can be obviously improved, bacterium breeding can be inhibited, stain adhesion can be avoided, and therefore the situation that a user gets ill due to frequent bacteria is avoided; and the nano titanium dioxide can decompose bacteria under the photocatalysis effect to achieve the antibacterial effect, so that the antibacterial performance can be further improved. 本发明涉及高分子材料领域，具体涉及一种高抗菌卫生的键帽材料及其制备方法，用于解决现有的键帽材料抗菌卫生性能不佳的问题；该制备方法中以PBT树脂、PP树脂为主要原料，向其中加入活性物质后能够明显的提升其抗菌抑菌性能以及疏水效果，能够抑制细菌滋生
