A kind of amorphous nano-titanium dioxide sandwich pavement brick and preparation method thereof

Abstract

An amorphous nano-titanium dioxide sandwich pavement brick belongs to the technical field of building materials. The sandwich pavement brick includes a bottom layer, a middle layer and a surface layer. The bottom layer is prepared from the following raw materials in parts by weight, 30-35 parts of slag ash, 35-40 parts of cement, 30-35 parts of stone powder, 5-10 parts of epoxy resin and 0.05-0.1 part of epoxy resin curing agent; the middle layer is prepared from the following raw materials in parts by weight, 15-20 parts of slag ash, 35-40 parts of waste plastic powder, 25-30 parts of cement, 15-20 parts of stone powder, 10-15 parts of epoxy resin and 0.1-0.15 parts of epoxy resin curing agent; the surface layer is prepared from the following raw materials in parts by weight, Amorphous Nano TiO 2 20-25 parts, 15-20 parts of slag ash, 5-10 parts of waste plastic powder, 30-35 parts of cement, 15-20 parts of stone powder, 15-20 parts of epoxy resin and 0.15-0.2 parts of epoxy resin curing agent. The sidewalk brick of the present invention contains amorphous nano-TiO 2 The sandwich structure with Venturi effect is light, breathable, and environmentally friendly. Under visible light, it can efficiently degrade air pollution gases.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to an amorphous nano-titanium dioxide sandwich pavement brick and a preparation method thereof, in particular to a sandwich pavement brick which can efficiently utilize visible light to catalyze and degrade air pollutants. Background technique [0002] In recent years, smog weather has occurred frequently all over the country, and the main constituents of smog are nitrogen oxides (NO x ), sulfur oxides (SO x ), carbon oxides (CO), hydrocarbons (HC) and other organic gaseous compounds (VOC) and other gas pollutants, due to their concentration exceeding the standard, lead to the deterioration of haze weather and seriously affect people's quality of life. As the largest project in human life, research on photocatalytic materials that can photocatalytically degrade the main components of smog and construction of environmentally friendly road surfaces is of great significance f...
