Non-yellowing key and manufacturing method thereof

The invention relates to the technical field of keys, and concretely relates to a non-yellowing key and a manufacturing method thereof. The non-yellowing key comprises, by weight, 50-90 parts of ABS resin, 20-40 parts of AS resin, 10-20 parts of a halogen-free flame retardant, 1-5 parts of a compatibilizer, 1-3 parts of an anti-yellowing agent and 0.5-1.5 parts of an anti-ultraviolet agent. The non-yellowing key adopting the AS resin, the anti-yellowing agent and the anti-ultraviolet agent has good yellowing resistance, can maintain the original white effect for a long time, and also has goodmechanical and physical properties. 本发明涉及琴键技术领域，具体涉及种不发黄琴键及其制造方法，所述不发黄琴键包括如下重量份的原料：ABS树脂50-90份、AS树脂20-40份、无卤阻燃剂10-20份、相容剂1-5份、耐黄变剂1-3份、抗紫外线剂0.5-1.5份。本发明的不发黄琴键通过采用AS树脂、耐黄变剂和抗紫外线剂，耐黄变效果好，可以长期保持原有白色效果；还具有良好的机械物理性能。
