Description

Technical Field

[0001] This invention relates to the field of transparent decorative materials technology, and in particular to a transparent decorative sheet or strip made by adjusting the refractive index of the material and a method for making it. Background Technology

[0002] Existing transparent decorative materials mainly include translucent imitation jade and marble products made with unsaturated resin as a binder and agate-grade aluminum oxide, glass powder, and transparent powder as fillers. The unsaturated resin used in these products has a refractive index of 1.56, similar to that of agate-grade aluminum oxide and glass powder, thus contributing to the product's transparency. However, these products suffer from several drawbacks: unsaturated resin is solvent-based, posing significant environmental concerns; they are also expensive; and they have poor weather resistance and a limited range of material choices. The inventor's inventions, including "A Jade-like Soft Porcelain and its Manufacturing Method (Patent No. 2022105478207)," "A Multi-Layer Flexible Transparent or Semi-Transparent Building Decorative Sheet and its Manufacturing Method (Patent No. 2021116801851)," "A Flexible Semi-Transparent Building Wall and Floor Decorative Sheet (Patent No. 2021116801847)," and "A Jade-like Sheet, Plate, or Strip with Large-Diameter Transparent Filler and its Manufacturing Method (Patent No. 2022110155130), all achieve product transparency by utilizing the inherent transparency of the binder (emulsion, adhesive powder, resin) and filler. The method of improving transparency relies entirely on increasing the amount of binder used. Therefore, material selection is severely restricted, leading to high material costs, hindering large-scale production, and resulting in unsatisfactory product transparency. Summary of the Invention

[0003] The purpose of this invention is to provide a method for manufacturing transparent decorative sheets or strips by adjusting the refractive index of materials. This method involves adjusting the refractive index of the materials, especially the binder, through a refractive index modifier or radiation irradiation. This makes the refractive index of the binder similar to or the same as that of different fillers, thereby greatly expanding the range of material choices, providing a prerequisite for selecting low-cost materials, and ultimately reducing material costs, facilitating large-scale production. While increasing the transparency of the product, it also facilitates the presentation of rich transparency gradients, resulting in a more exquisite decorative effect.
