Embodiment 1

[0028] Follow the steps below to prepare ceramsite bricks:

[0029] S1. Add deionized water, maleic acid and 1 / 3 weight of ammonium persulfate into the reaction flask, adjust the pH value to 3.5, vacuumize, and start stirring after nitrogen gas is introduced. After the temperature is raised to 45°C, 2-pyrrolidone, Tetradecyl dimethyl benzyl ammonium chloride, chitosan, absolute ethanol and 2 / 3 weight of ammonium persulfate were added to the reaction flask, heated to 85°C and stirred for 4.5 hours to obtain a reaction solution. The solid was obtained after suction filtration under reduced pressure. The solid was washed 3 times with absolute ethanol and dried at 90°C for 5 hours to obtain additive A, deionized water, maleic acid, ammonium persulfate, 2-pyrrolidone, tetradecane The ratio of dimethyl benzyl ammonium chloride, chitosan and dehydrated alcohol is 90mL:3.6g:1.5g:4g:5g:2g:50mL;

Abstract

The invention provides a kind of preparation method of ceramsite brick, comprises the following steps: S1. deionized water, maleic acid, 2-pyrrolidone, tetradecyl dimethyl benzyl ammonium chloride, chitosan, free Water ethanol and ammonium persulfate react to obtain auxiliary agent A; S2. Mix, stir, dehydrate and dry the sludge and auxiliary agent A to obtain dried sludge; S3. Dry distill the dried sludge, remove iron, remove After sieving to obtain sludge pellets; S4. High-temperature treatment and screening of sludge pellets to obtain sludge powder; S5. Reaction of absolute ethanol, oleic acid, and n-propylamine to obtain additive B; S6. Mix mud powder, additive B, coal gangue, and water, stir evenly to obtain slurry, press the slurry to obtain ceramsite bricks, dry the ceramsite bricks, transfer them to an autoclave and autoclave them to obtain ceramsite bricks . The ceramsite brick prepared by the invention has good mechanical properties and water permeability.

Description

technical field [0001] The invention relates to a preparation method of ceramsite bricks. Background technique [0002] At present, the treatment methods for sludge produced by factories such as sewage treatment and river cleaning are generally discarded, incinerated, or landfilled. These treatment methods not only occupy land, but also pollute the environment. After the relocation of many factories, the land occupied by the original factory buildings is polluted and needs to be treated. [0003] Ceramsite brick is a concrete hollow block made of lightweight clay ceramsite, which has the advantages of fire prevention, light weight, high strength, heat insulation and moisture resistance. At present, the country prohibits building kilns and burning bricks, which leads to the reduction of raw materials for ceramsite bricks. Therefore, relevant manufacturers have developed a method of using waste such as sludge as raw materials for ceramsite bricks. [0004] The Chinese invent...
