Abstract

The invention relates to a gradient layer calcium carbonate-calcium silicate total-reflection film and a preparation method thereof. The gradient layer calcium carbonate-calcium silicate total-reflection film comprises a substrate, a calcium carbonate layer, a calcium silicate layer and a silicon oxide layer which are sequentially arranged, and the calcium carbonate layer, the calcium silicate layer and the silicon oxide layer are sequentially attached to the substrate. Calcium carbonate and calcium silicate are adopted as layer materials, the raw materials are easy to obtain, low in price, environmentally friendly and non-toxic, the optical total-reflection film can be designed into a calcium carbonate/calcium silicate/silicon oxide multilayer structure, refraction and reflection controlover light rays with different wavelengths is achieved, total reflection of light rays with different wavelengths is achieved, and the reflection effect is good.

Description

technical field [0001] The invention relates to the technical field of all-reflective films, in particular to a gradient-layer calcium carbonate-calcium silicate full-reflection film and a preparation method thereof. Background technique [0002] Total reflection film is a material that can maximize the high reflection of light without loss, and is widely used in optical fiber, lens and other technical fields. In traditional technology, the most widely used material in the all-reflection film industry is calcium fluoride (CaF 2 ), but the cost of calcium fluoride material is high, and it is slightly soluble in water, and its lifespan is low, and the preparation process of fluorine-containing products will involve environmental protection issues. Contents of the invention [0003] Based on this, it is necessary to address the above problems and provide a gradient layer calcium carbonate-calcium silicate total reflection film, which can realize total reflection for differen...
