Low-cost waterproof anti-aging construction brick

Abstract

The invention discloses a low-cost waterproof anti-aging construction brick which comprises the following raw materials by weight part: 0.5-1.5 parts of ethylene-vinyl acetate copolymer, 1.5-2.5 parts of cellulose hydroxypropyl methyl, 0.4-0.8 part of polysiloxane powder, 8-16 parts of modified montmorillonite, 10-20 parts of coal ash, 8-16 parts of calcium hydroxide, 20-30 parts of clay, 8-16 parts of stone wastes, 3-7 parts of silicon nitride, 3-9 parts of kieselguhr, 3-7 parts of magnesium oxide, 25-35 parts of cement and 10-20 parts of argil. A preparation method for the modified montmorillonite comprises the following steps: stirring montmorillonite powder, oxalic acid and sodium dihydrogen phosphate; standing by; extracting upper-layer turbid liquid; adding sodium hydroxide into the turbid liquid and stirring; adding oxalic acid and stirring; adding monopotassium phosphate and stirring; adding ethylene diamine tetraacetic acid disodium and stirring; centrifuging, drying and crushing; adding silane coupling agent and water; adjusting pH value, stirring and filtering; washing; adding glutaraldehyde aqueous solution and stirring; filtering, washing and drying, thereby acquiring the modified montmorillonite.

Description

technical field [0001] The invention relates to the technical field of building bricks, in particular to a low-cost waterproof and aging-resistant building brick. Background technique [0002] With the rapid development of science and technology and industry, the corrosion of building bricks is becoming more and more serious under harsh environments. Usually, building bricks are more sensitive to corrosion environments. Through the study of existing data, the corrosion environment affects building bricks to a certain extent. In recent years, with the rapid development of my country's building ceramics industry, people have higher and higher requirements for the performance of building bricks. At present, the functions of building bricks in the market are relatively single. How to improve the corrosion resistance, aging resistance and fire resistance of building bricks has become a technical problem to be solved at present. Contents of the invention [0003] Based on the tec...
