Abstract

The invention discloses a decorative board and a preparation method thereof. The decorative board comprises the following components in parts by weight: 10-20 parts of diatom mud, 7-15 parts of titanium dioxide, 5-10 parts of talcum powder, and 8 parts of tourmaline ~15 parts, 10~20 parts of perlite and 40~60 parts of building gypsum powder; it is prepared by the following steps: (1) According to the composition of the components, diatom mud, titanium dioxide, talcum powder, tourmaline, perlite, Building gypsum powder and water are evenly mixed to obtain a mixture; (2) The mixture is solidified and formed in a mechanical film-forming belt or a mold, and a block-shaped solid plate is obtained after demolding, and then dried. The decorative board of the present invention has the functions of removing formaldehyde, antibacterial and fresh air, can be used as decorative materials such as indoor ceiling boards and inner wall boards, and meets people's requirements for environmental protection and health of the living environment. The preparation method of the invention has simple process, has no adverse effect on operators during production, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a decorative board and a preparation method thereof. Background technique [0002] According to the Environmental Testing Center of the China Interior Decoration Association, the number of deaths caused by interior decoration pollution in the country has reached 111,000 every year, which is an astonishing figure. Among them, formaldehyde is one of the main sources of indoor environmental pollution. It usually comes from artificial boards, adhesives, wallpapers and other materials. It is a world-recognized potential carcinogen, and it can also cause fetal malformation. However, how to eliminate the formaldehyde pollutants caused by interior decoration, there is no good treatment method at present. Opening windows for ventilation can only temporarily reduce the concentration of formaldehyde pollutants, and in many cases the windows cannot be opened for a long time. More importantly, formaldehyde pollution sources are constantly ...
