Embodiment Construction

[0014] An aerated brick for purifying air, which is made from the following raw materials in parts by weight:

[0015] Diatomaceous earth 30, coffee charcoal 5, titanium dioxide 3, cement 20, silicone resin YR33703, phenolic resin 2, silane coupling agent KH-5700.3, sodium alginate 0.3, aluminum powder 0.1, konjac gum 1, sodium tripolyphosphate 1. Modified silica sol 5;

[0016] Wherein the modified silica sol is made of the following raw materials in parts by weight: 0.3 of alkenyl succinic anhydride, 0.3 of guar gum, 10 of silica sol with a solid content of 30%, 0.3 of sodium lignosulfonate, and 10 of water; The preparation method is to add sodium lignin sulfonate and alkenyl succinic anhydride into water and stir evenly, then add guar gum and stir at 60°C for 0.5h, after cooling, add silica sol and stir evenly to obtain the product.

[0017] A preparation method of an air-purifying aerated brick, comprising the following steps:

[0018] (1) Weigh raw materials by weight, ...

Abstract

The invention discloses an air-purifying aerated brick, which is prepared from the following materials in parts by weight: 30 to 40 parts of diatomite, 5 to 10 parts of coffee carbon, 3 to 5 parts of titanium dioxide, 20 to 30 parts of cement, 3 to 5 parts of organic silicon resin YR3370, 2 to 4 parts of phenolic resin, 0.3 to 0.5 parts of silane coupling agent KH-570, 0.3 to 0.5 parts of sodium alginate, 0.1 to 0.2 parts of aluminium powder, 1 to 2 parts of konjac glucomannan, 1 to 2 parts of sodium tripolyphosphate and 5 to 10 parts of modified silica sol. The aerated brick disclosed by the invention not only has good waterproofness, seepage resistance, cracking resistance and pressure resistance and high durability, but also can efficiently adsorb and remove harmful substances in the air, and the aerated brick has the effects of purifying the air and improving the environment, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an air-purifying aerated brick and a preparation method thereof. Background technique [0002] Aerated bricks are made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) , pre-curing, cutting, autoclaving, curing and other processes made of a lightweight, porous new building material, with light weight, strong fire resistance, good heat preservation effect, good processability, low price and other excellent characteristics, is A relatively ideal wall material has gradually replaced traditional wall materials such as red bricks and has been widely used. However, the water absorption rate of aerated bricks is high, and there are problems of poor impermeability and crack resistance. During the application process, cracks are easy to occur, and its facing is easy to bubble and fall off, which affects the performance and construction quality. Furt...
