振膜材料及其制备方法和应用

本发明公开了一种振膜材料及其只备份方法和应用，振膜材料包括如下重量份的原料：LCP溶液100～140份、玻璃纤维粉15～30份、填充剂10～20份、增强剂5～10份和增韧剂5～10份。通过玻璃纤维对LCP溶液进行改性，且振膜材料采用三层结构，避免了掺杂玻璃纤维粉所导致的表面粗糙和断裂伸长率降低的问题，并且使得振膜材料具备更强的刚性，使其在高频段振动时能有效抑制分割振动。 The invention discloses a vibrating diaphragm material, and a preparation method and application thereof. The vibrating diaphragm material comprises, by weight, 100-140 parts of an LCP solution, 15-30parts of glass fiber powder, 10-20 parts of a filling agent, 5-10 parts of a reinforcing agent and 5-10 parts of a toughening agent. The LCP solution is modified through the glass fibers, and the vibrating diaphragm material adopts a three-layer structure, so that the problems of surface roughness and elongation at break reduction caused by doping of glass fiber powder are avoided, the vibratingdiaphragm material has higher rigidity, and segmentation vibration can be effectively inhibited when the vibrating diaphragm material vibrates at a high frequency band.
