摘要
以g-C_3N_4/TiO_2复合材料、硅藻土、六偏磷酸钠、硅丙乳液为原料,制备了具有可见光催化性能的涂料。当催化剂(g)、硅藻土(g)、硅丙乳液(ml)的比例为7:3:10,分散剂六偏磷酸钠含量为催化剂和硅藻土含量的0.56%,30min内对NO_x气体降解率达到50.72%。用XRD、FTIR、UV-vis、DSC差热分析对涂膜进行了表征,结果表明,制备的光催化涂料的活性成分为g-C_3N_4和TiO_2,表现出较强的紫外、可见光吸收能力。
The photocatalysis coating was prepared with g-C3N4/TiO2 composite material, diatomite, six sodium hexametaphosphate and silicone acrylic emulsion as.the raw materials.When the catalyst （g）, diatomite （g）, Silicone acrylic emulsion （ML） ratio of 7：3：10, dispersant six sodium metapbosphate content as catalyst and Diatomite Content of 0.56%, which is coated on the metal plate, It was found that the degradation rate of NOx -was 50.72% in 30 minutes. The photocatalysis coating were characterized by XRD, FT-IR, UV-vis and DSC. The results showed that the active components of the coatings were g-C3N4 and Tie2 , and It showed strong absorption ability to both UV and visible light.
