Blue light test paper and preparation method thereof

The invention relates to blue light detection test paper and a preparation method thereof. The preparation method comprises the following steps: 1) providing a base material; 2) silver bromide powder is dissolved in a saturated salt solution to form an impregnation liquid, and the ratio of the silver bromide powder to the saturated salt solution is 1-4 g/1000 ml; (3) the base material is soaked in the steeping liquor and soaked for 2-5 seconds; (4) the base material is fished out of the steeping liquor and dried; and 5) after drying, coating the substrate with a transparent sealing layer to prepare the blue light detection test paper. The blue light intensity in related lamps on the market can be conveniently and quickly detected, and people can quickly distinguish the blue light intensity in light. 本发明涉及一种蓝光检测试纸及其制备方法，所述制备方法包括以下步骤：1)、提供一基材；2)、将溴化银粉末溶于饱和盐溶液中形成浸渍液，其中，所述溴化银粉末与所述饱和盐溶液的比例为1-4g/1000ml；3)、将所述基材浸泡到所述浸渍液中并浸泡2-5秒；4)、将所述基材从所述浸渍液中捞出并干燥；5)、干燥后在所述基材上包覆透明密封层，制得所述蓝光检测试纸。其可以方便快捷地检测出市场上相关灯具中的蓝光强度，有利于人们快速分辨出灯光
