检测玻璃微珠逆反射性能的方法
摘要：
本发明公开了检测玻璃微珠逆反射性能的方法，检测步骤为：在透明薄膜基材上涂布胶粘剂，放入烘箱中干燥，干燥温度为50～160℃，干燥时间为1～5分钟；将取出的薄膜涂胶面朝上平放于平整的台面上，在涂胶面上撒上玻璃微珠，形成植珠膜；将植珠膜放入烘箱中干燥，干燥温度为80～160℃，干燥时间为3～10分钟，玻璃微珠埋入于胶粘剂的深度为玻璃微珠直径的30～90%；在植珠膜上涂布聚焦胶水形成聚焦膜；将聚焦膜放入烘箱，干燥温度为70～160℃，干燥时间为5～15分钟；将聚焦膜进行镀铝，形成镀铝薄膜；使用逆反射系数测试仪测试玻璃微珠的逆反射系数。该方法简便、可操作性强，提高了产品合格率和生产效率。
摘要（英）：

The invention discloses a method used for detecting retroreflection performance of a glass microbeads. The method comprises the following detecting steps of: coating an adhesive on a transparent film base material, placing a baking oven, and drying at the drying temperature of 50-160 DEG C for 1-5 minutes; placing the film on a smooth table top with the surface coated with the adhesive upward, casting the glass microbeads on the surface coated with the adhesive to form a bead-planted film; placing the bead-planted film in the baking oven, and drying at the drying temperature of 80-160 DEG C for 3-10 minutes, wherein the depth of the glass microbeads buried in the adhesive is 30-90% of the diameter of the glass microbeads; coating focusing gluewater on the bead-planted film to form a focusing film, placing the focusing film in a baking oven, and drying at the drying temperature of 70-160 DEG C for 5-15 minutes; and aluminizing the focusing film to form an aluminized film, and testing the retroreflection factor of the glass microbeads by utilizing a retroreflection factor test instrument. The method disclosed by the invention has the advantages that the method is simple and convenient, the operability is strong, and the qualification rate and production efficiency of products are improved.
