Building decorative plate and manufacturing method thereof
The invention discloses a building decorative plate and a manufacturing method thereof. A decorative plate main body comprises: a material A comprising, by weight, 2-3% of modified pseudo-boehmite, 0.1-0.3% of graphene, 0.5-1.7% of tourmaline powder and 5-8% of a nano-TiO2 dispersion; a material B comprising, by weight, 5-10% of a magnesium hercynite refractory material; a material C comprising, by weight, 18-20% of Portland cement, 15-20% of quartz sands, 8-10% of expanded and vitrified micro-bubbles, 3-5% of bamboo charcoal powder and 1.4-2% of a foaming agent; a material D comprising, by weight, 5-10% of waterborne polyurethane resin emulsion; and the balance of water. The preparation method of the modified pseudo-boehmite comprises the following steps: grinding pseudo-boehmite, addingthe pseudo-boehmite into a dilute HNO3 solution, stirring for 2 hours, filtering, washing, adding into a mixed solution containing Fe(NO3)3, Cu(NO3)2 and AgNO3, dipping for 3 hours, dropwise adding anammonia water solution, reacting for 1-3 hours, filtering, and roasting at 400-550 DEG C for 4 hours. The prepared building decorative plate is excellent in performance, the soaking expansion rate issmaller than or equal to 0.10 mm/m, the formaldehyde purification rate is larger than or equal to 92.1%, the formaldehyde purification lasting rate is larger than or equal to 89.6%, the escherichia coli antibacterial rate is larger than or equal to 99.9%, and the fire resistance grade reaches the A grade.
本发明公开一种建筑装饰板及其制作方法，装饰板主体包括以下重量百分比原料：A料：改性拟薄水铝石2～3％、石墨烯0.1～0.3％、电气石粉0.5～1.7％、纳米TiO分散液5～8％；B料：镁铁铝尖晶石耐火材料5～10％；C料：硅酸盐水泥18～20％、石英砂15～20％、膨胀玻化微珠8～10％、竹炭粉3～5％、发泡剂1.4～2％；D料：水性聚氨酯树脂乳液5～10％、水补足余量；改性拟薄水铝石制备方法如下：研磨拟薄水铝石后，加入稀HNO溶液中搅拌2h，过滤、洗涤后，再加入含Fe(NO)、Cu(NO)、AgNO的混合溶液中浸渍3h，滴加氨水溶液反应1～3h，过滤后，400～550℃焙烧4h。本发明制备出的建筑装饰板性能优异，浸水膨胀率≤0.10mm/m，甲醛净化率≥92.1％，甲醛净化持久率≥89.6％，大肠杆菌抗菌率≥99.9％，抗火等级达到A级。
