阅读说明：本技术 曲面镜用热塑性树脂基板及其制备方法 (Thermoplastic resin substrate for curved mirror and preparation method thereof ) 是由 任天孝 杨佳 施岳林 于 2020-05-08 设计创作，主要内容包括：本发明涉及一种曲面镜用热塑性树脂基板及其制备方法与包含其的曲面镜及抬头显示器。所述制备方法包括以下步骤：A)将注塑机的模具升温至130-190～(o)C范围内的温度并闭合模具,B)将熔融热塑性树脂注入模具腔体中,C)向所述腔体施加300-700bar的压力并保持5秒以上的时间段,D)停止施加压力并在10-50秒内将所述模具的温度降低至60-100～(o)C范围内的温度,和E)打开所述模具并取出成型的热塑性树脂基板,其中在向所述腔体施加压力之前,在模具腔体的分型面处保留0.3-1mm的间隙。根据本发明的热塑性树脂基板具有大尺寸、高的尺寸稳定性及低的表面粗糙度,可以应用在未来增强型抬头显示器上,实现大面积、远距离投影和高精度成像,从而满足未来汽车对驾驶安全性和舒适性上的要求。(The invention relates to a thermoplastic resin substrate for a curved mirror, a preparation method thereof, the curved mirror comprising the thermoplastic resin substrate and a head-up display comprising the curved mirror. The preparation method comprises the following steps: A) the temperature of the mold of the injection molding machine is raised to 130- o C and closing the mold, B) injecting a molten thermoplastic resin into the mold cavity, C) applying a pressure of 300-700bar to said cavityAnd maintaining for a period of time of more than 5 seconds, D) stopping the application of pressure and reducing the temperature of the mould to 60-100 seconds within 10-50 seconds o C, and E) opening the mold and removing the molded thermoplastic resin substrate, wherein a gap of 0.3-1mm remains at the parting plane of the mold cavity before applying pressure to the cavity. The thermoplastic resin substrate has large size, high size stability and low surface roughness, can be applied to a future enhanced head-up display, and realizes large-area and long-distance projection and high-precision imaging, thereby meeting the requirements of future automobiles on driving safety and comfort.)
