Abstract

The invention discloses a baking-free brick with an air purifying function and a preparation method of the baking-free brick, and relates to the technical field of baking-free bricks. The baking-free brick with the air purifying function comprises the following components: a mixture A and a mixture B, wherein the mixture A comprises the following components in parts by weight: river sand 70-85 parts, slag 40-60 parts, quick lime 30-40 parts, cement 10-15 parts, silica powder 5-8 parts, nano aluminium oxide 5-8 parts, clay 5-8 parts, ethanolamine 1-2 parts, waterglass 1-2 parts, and an early strength agent 1-2 parts; the grain size distribution of the river sand is 2-3 mu m 30wt%; the grain size of the nano aluminium oxide is 30-60 nm; and the mixture B comprises the following components in parts by weight: water 40-60 parts, acetic acid 8-9 parts, urea 20-30 parts, an emulsifying agent 3-3.5 parts, propylene carbonate 7-8 parts, melamine 3-3.5 parts, dicyandiamide 2-2.5 parts, polyacrylamide 0.03-0.05 part, and ethylacetoacetate 0.05-0.07 part.

Description

technical field [0001] The invention relates to the technical field of non-burning bricks, in particular to a non-burning brick with air purification function. Background technique [0002] Unfired bricks, also known as non-sintered bricks, can avoid the serious waste of land resources of traditional sintered bricks and the need for a large amount of fuel for sintering during the preparation process, and the emission of SO2 during the preparation process pollutes the environment. At present, unburned bricks have been widely used in the construction field. [0003] During the decoration process, some paint brush layers will be applied on the outer layer of unburned bricks. These paint brush layers are often accompanied by excessive formaldehyde release, which is not conducive to the personal safety of the occupants. The commonly used improvement method is to ventilate the painted room for a period of time or place some plants that can absorb formaldehyde, such as pothos, to ...
