Abstract

The invention provides a graphene diatom ooze paint capable of killing bacterial and removing aldehyde and its preparation method to overcome the problem that conventional paints are incapable of absorbing pollutants like aldehyde. The graphene diatom ooze paint capable of killing bacterial and removing aldehyde comprises the following raw materials by weight: 1 to 10 parts of graphene oxide, 30 to 50 parts of natural diatom ooze, 10 to 30 parts of white cement, 20 to 50 parts of an adsorbent, 5 to 10 parts of dispersible adhesive powder, 1 to 5 parts of cellulose, 5 to 20 parts of light calcium carbonate, 0.5 to 1 part of polypropylene fibers, 1 to 2 parts of wood fibers, 1 to 5 parts of nanometer silica, 1 to 10 parts of titanium dioxide, 1 to 5 parts of iron oxide pigment and 1 to 3 parts of sodium hexametaphosphate. The paint prepared in the invention is capable of decomposing formaldehyde; in an enclosed environment, formaldehyde efficiency of the paint is as high as 95% and benzene removal efficiency is 93%; and the paint can effectively remove harmful gas in a room and increase indoor negative ion concentration, and is beneficial for human health.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a graphene diatom mud sterilizing and dealdehyde coating and a preparation method thereof. Background technique [0002] In the process of interior decoration, a large amount of wood, paint, glue and paint are used. Since wood, paint, glue and paint contain a lot of pollutants: formaldehyde, benzene and total volatile organic compounds, the head of the household usually uses ventilation and placement before moving in. Activated carbon and green plants reduce the content of pollutants. [0003] Because the pollutants are sealed in the wood clips and glue, it is difficult to volatilize completely in a short time. After the householder moves in, in order to prevent external noise and dust pollution, he usually closes the doors and windows and lives in a poorly ventilated environment. , the residual pollutants will directly volatilize into the living environment, endangeri...
