Problems solved by technology

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 prone to occur, and the veneer is easy to bubble and fall off, which affects the performance and construction quality. Bricks have poor anti-static performance and are not suitable for use in working environments that require no static electricity. Further development and improvement are needed

Embodiment Construction

[0014] An antistatic aerated brick containing flake graphite, which is made from the following raw materials in parts by weight:

[0015] Mica powder 20, flake graphite 10, cement 30, silicone resin YR3370 3, phenolic resin 2, silane coupling agent KH-570 0.3, dodecyltrimethylammonium chloride 0.3, hydroxyl silicone oil 0.3, ethylenediaminetetra Disodium acetate 0.5, aluminum powder 0.1, erucamide 0.5, 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 first add sodium lignosulfonate 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.

Abstract

The invention discloses an antistatic aerated brick comprising flake graphite, made from the following materials according to parts by weight: 20-30 parts of mica powder, 10-15 parts of flake graphite, 30-40 parts of cement, 3-5 parts of organosilicon resin YR3370, 2-4 parts of phenolic resin, 0.3-0.5 part of silane coupling agent KH-570, 0.3-0.5 part of dodecyl trimethyl ammonium chloride, 0.3-0.5 part of hydroxyl silicone oil, 0.5-1 part of ethylenediamine tetraacetic acid disodium salt, 0.1-0.2 part of aluminum powder, 0.5-1 part of erucamide, and 5-10 parts of modified silica sol. The aerated brick of the invention has good waterproof, anti-permeation and anti-cracking properties, good pressure resistance, high durability and good antistatic property, is suitable for work environments requiring zero static electricity and is highly practical.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flake-containing graphite antistatic 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 prone to occur, and the veneer is easy to bubble and fall off, which affects the performance and con...
