Problems solved by technology

[0006] Distributed silicon solar photovoltaic cells are mainly installed on the roofs and glass curtain walls of residential buildings, factories, and commercial buildings, and are mainly distributed in urban areas and suburbs. At present, the appearance of this dark blue or black silicon solar photovoltaic cells is extremely inconsistent with the surrounding environment , which only has the power generation function, cannot meet people’s aesthetic needs for the environment, and even causes urban light pollution, which limits the market promotion of distributed silicon solar roofs and curtain walls

Embodiment 1

[0039] A color-changing ink with the scene, comprising 7 parts by weight of a photosensitive polymer, 8 parts by weight of a photoactive monomer, 1 part by weight of a photosensitizer, 30 parts by weight of a weather-resistant resin, 1 part by weight of a curing agent, and 1 part by weight of a pearlescent pigment.

[0040] Wherein the photosensitive polymer is a hydrophobic polyester urethane acrylate with a functionality of 2 to 6, specifically RUA-064S-8 from Japan Asia Corporation; the photoactive monomer is isobornyl acrylate (IBOA); the photosensitizer is 1-hydroxy Cyclohexyl benzophenone (184); the weather resistance resin is a fluorocarbon resin, specifically the fluorocarbon resin of Sanai Fu Zhonghao Chemical New Material Co., Ltd. such as: chlorotrifluoroethylene and vinyl ester alternating copolymer JF-3X ( Fluorine content 25±0.5%, hydroxyl value mgKOH / g / solid 50±5, solid content> 50%), can be cross-linked at room temperature, can also use amino or blocked isocyanate...

Embodiment 1-1

[0042] The photosensitive polymer is EB4680 polyurethane acrylate of Allnex Resin (Shanghai) Co., Ltd., which can achieve the same effect as in Example 1.

Embodiment 1-2

[0044] The photosensitive polymer is acrylated acrylate ACAZ-251, which can achieve the same effect as in Example 1.

Abstract

The invention discloses an ink capable of changing the color with scene. The ink comprises, by weight, 7-30 parts of a photosensitive polymer, 8-20 parts of a photoactive monomer, 1-5 parts of a photosensitizer, 30-55 parts of a weather-resistant resin, 1-10 parts of a curing agent and 1-15 parts of a pearlescent pigment. The pearlescent pigment is at least one of interference-type pearlescent pigments having weather resistance, the interference-type pearlescent pigments have no color, and every sheet of the pearlescent pigments can be regarded as a mini-sized prism, and can decompose white composite light into varicolored monochrome lights in order to a printing ink coating present beautiful pearl luster and metal luster. The color of a pattern, seen by human eyes, is the result of the mutual superposing and mutual interference of multiple reflections and refractions of the transparent pearlescent pigment sheet to incident light.

Description

technical field [0001] The invention relates to the technical field of solar panel surface decoration, in particular to a color-changing ink with the scene. Background technique [0002] Solar photovoltaic cells are a new type of power generation system that uses the photovoltaic effect of materials to directly convert solar radiation energy into electrical energy, including silicon solar photovoltaic cells, thin-film solar photovoltaic cells, and perovskite solar photovoltaic cells. [0003] Silicon solar photovoltaic cells occupy the mainstream of the market, while thin-film solar photovoltaic cells and perovskite solar photovoltaic cells have just entered the commercialization stage. [0004] The traditional structure of silicon solar photovoltaic cells is composed of tempered glass, EVA film, high conversion efficiency monocrystalline silicon or polycrystalline silicon solar cells, EVA film and back plate from the outside to the inside, and is fixed with an aluminum allo...
