Problems solved by technology

The composite board produced by the above-mentioned patent does not have the antibacterial effect because the composite board produced by using waste plastics, various industrial waste residues, industrial gypsum and other raw materials does not have antibacterial effect. The growth of a large number of bacteria on the surface of the composite board will cause the board to become mildewed, and then produce germs that will endanger the health of the installers

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environmentally friendly building board and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy and the advancement of urban-rural integration, various major construction projects have come one after another. They have become a beautiful landscape of modern cities with their unique charm. The use of building panels is inseparable from these major construction projects, such as support formwork and wall formwork, interior wall decoration panels, and floors used in pouring concrete in construction projects. The performance of these building panels directly affects the quality of construction projects and the effect of decoration. Therefore, it is particularly important to develop building panels with excellent performance. [0003] At present, the commonly used building boards in constructio...
