背景技术 Background technique
目前世界各国道路划线采用在油漆表面粘玻璃珠产生定向反光的方法, 中国专 利 97202912号和国际申请号为 PCT US95 U8686的专利申请公开了用有机粘结剂将 基体和玻璃珠粘结在一起的方法, 上述方法及其产品在使用中有一些问题: 油漆划 线的有机粘结剂易粘污物变黑, 自洁性能差, 粘结的玻璃珠易脱落, 失去反光和诱 导作用, 有机粘结剂也易脱落, 尤其是在水泥路面半年就脱落了。 因此需反复划线, 耗费人力、 物力, 浪费很大, 并影响交通安全, 反光膜颜色和粘结剂在七至十年左 右褪色脱落, 不能在建筑物上作持久装饰广告。 At present, the road marking of various countries around the world adopts a method of producing directional reflection by adhering glass beads on the surface of paint. The patent applications of Chinese Patent No. 97202912 and International Application No. PCT US95 U8686 disclose that the substrate and the glass beads are bonded together with an organic binder There are some problems in the use of the above method and its products: the organic binder of the paint scribing is easy to stick to the dirt, the self-cleaning performance is poor, the bonded glass beads are easy to fall off, and the reflection and induction are lost. Organic The adhesive is also easy to fall off, especially on the cement pavement in half a year. Therefore, it is necessary to repeatedly draw lines, which consumes manpower, material resources, a great waste, and affects traffic safety. The color of the reflective film and the adhesive fade and fall off in about seven to ten years, and it cannot be used as a durable decorative advertisement on the building.
