Stone plastic wallboard capable of removing formaldehyde and resisting bacteria as well as preparation method and application of stone plastic wallboard
The invention relates to the technical field of plates and plate preparation, in particular to a stone-plastic wallboard, a preparation method and application thereof.The stone-plastic wallboard comprises a base plate and a face plate, the base plate is a polyvinyl chloride plate, the face plate is a stone-plastic face plate, and the polyvinyl chloride plate is fixedly connected with the stone-plastic face plate; a photocatalyst-quantum dot composite material is fixed on the surface of the stone-plastic panel, the photocatalyst-quantum dot composite material comprises the following components in percentage by mass: 40-60% of nano titanium dioxide, 30-50% of carbon quantum dots, 5-15% of a dispersing agent and 1-5% of silver salt, and in the material, the nano titanium dioxide is combined with the carbon quantum dots to form the photocatalyst-quantum dot composite material. And with the assistance of the dispersing agent and the silver ions, the transmission of photo-induced electrons is enhanced, the compounding of the photo-induced electrons and holes is inhibited, and the photocatalytic effect of the nano titanium dioxide is enhanced, so that the composite material can accelerate the decomposition of volatile organic compounds under independent natural light, and the stone-plastic wallboard has the function of removing formaldehyde.
本发明涉及板材及板材制备技术领域，特别涉及一种石塑墙板、制备方法及其应用，该石塑墙板包括基板和面板，所述基板为聚氯乙烯板，所述面板为石塑面板，所述聚氯乙烯板与石塑面板固定连接，所述石塑面板表面固定有光触媒‑量子点复合材料，所述光触媒‑量子点复合材料各组分按质量百分比计包括：纳米二氧化钛40‑60％，碳量子点30‑50％，分散剂5‑15％，银盐1‑5％，该材料中纳米二氧化钛与碳量子点结合，再加上分散剂和银离子的辅助，增强光生电子的传输，抑制光生电子与空穴的复合，增强纳米二氧化钛的光催化效应，使得该复合材料能够在单独的自然光下加快分解挥发性有机物，从而使得本发明石塑墙板自身具有除甲醛的功能。
