Embodiment Construction

[0032]In terms of parts by weight, weigh 40 to 50 parts of concentrated sulfuric acid with a mass fraction of 80 to 90%, 1 to 3 parts of sodium nitrate powder and 2 to 4 parts of graphite powder into a three-necked flask, and place the three-necked flask at a water bath temperature In a water bath at 0-5°C and stir with a stirrer at a speed of 300-350r / min for 10-15min, after stirring and mixing, add 5-8 parts of potassium permanganate powder and continue stirring for 10-15min, then raise the temperature of the water bath to 35 ~40°C, constant temperature reaction for 30-40min, to obtain a dark brown liquid; add deionized water with a mass of 200-240% of the above dark brown liquid into the three-necked flask, raise the temperature of the water bath to 88-92°C, and constant temperature reaction for 15-18min, To obtain the mixed solution, add 20-30% of the mixed solution to the mixed solution and add hydrogen peroxide with a mass fraction of 20-25%, keep the temperature of the w...

Abstract

The invention relates to the technical field of preparation of building materials, in particular to a preparation method of a high-strength permeation-resistant aerated brick. The preparation method includes the following steps of introducing metal ions into graphene oxide to obtain a metal composite, preparing a nano-silica hybridization modified polysiloxane composite, mixing the metal compositewith raw materials of the aerated brick to prepare the aerated brick, soaking an aerated brick green body in the nano-silica hybridized polysiloxane composite, and finally obtaining the high-strengthpermeation-resistant aerated brick through maintenance. The preparation method has the advantages that the prepared graphene oxide metal composite is added into the aerated brick, and accordingly, the aerated brick has ultrahigh strength and tenacity; through addition of silver, the aerated brick has antibacterial capability at the same time; modified polysiloxane and modified nano-silica are subjected to sol reaction to compound nanoscale hybridized polysiloxane, a super-hydrophobic film is formed on the surface of the aerated brick after the aerated brick is soaked in the nanoscale hybridized polysiloxane, the water contact angle is increased, permeation resistance of the aerated brick is improved, and accordingly, the aerated brick has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a method for preparing a high-strength anti-permeation aerated brick. Background technique [0002] Aerated bricks are also called aerated concrete blocks, which are aerated concrete blocks produced by high-temperature autoclaved equipment. Using siliceous materials (sand, fly ash and silicon-containing tailings, etc.) Lightweight porous silicate products made by autoclaving, curing and other processes. It can be made into blocks, plates and insulation products of different specifications, and is widely used in load-bearing or enclosure filling structures of industrial and civil buildings. building materials. [0003] Aerated brick is a lightweight and porous new building material, which has the advantages of light capacity, high thermal insulation performance, good sound absorption, strong shock resistance, strong adaptability, good processing performanc...
