Embodiment Construction

[0019] The mixed waste slag is formed by mixing and grinding coal gangue and blast furnace slag at a mass ratio of 3-5:2-6.

[0020] The surfactant is any one of sodium lauryl sulfate and lauryl dimethyl ammonium bromide.

[0021] The animal bone meal is pig bone and chicken bone, which are put into a pulverizer according to the mass ratio of 4-7:2-5 for crushing, passed through a 200-mesh sieve, and the sieved particles are collected to obtain the bone meal.

[0022] The dispersant is any one of magnesium stearate and sodium stearate.

[0023] The auxiliary agent is calcium hydroxyphosphate, bamboo chips and tetrabutyl titanate mixed in a mass ratio of 3-6:1:3.

[0024] The additive is any one of tetrabutylammonium bisulfate and cyclodextrin.

[0025] A preparation method of a composite permeable brick, the preparation method comprising the steps of:

[0026] (1) Take the mixed waste residue and 0.6mol / L hydrochloric acid solution according to the mass ratio of 1:4~6, stir...

Abstract

The invention relates to a preparation method of composite permeable bricks, belonging to the technical field of building materials. Coal gangue and blast furnace slag are used as basic materials; particles are activated by using hydrochloric acid to removing impurities, carrying out expanded void treatment and using a surfactant and a physical grinding-aid method; the activated particles with improved activity are then mixed with sea mud, animal bone powder and the like; a dispersing agent is used for improving the sufficient dispersing and mixing of the raw materials; in a calcination process, the sea mud is firstly enabled to form ceramic-like particles, and the gas generated by the decomposition of bamboo chips and additives in auxiliary agents is used for pore formation so as to formpores; secondly, bone char is formed by the animal bone powder, so that the biological activity and the water permeability are improved; finally, hydroxyl calcium phosphate is combined with calcium carbonate in the raw materials so as to form synthetic bone char, so that the activity is further improved; furthermore, tetrabutyl titanate is decomposed to generate dioxide silicon, so that the self-cleaning effect of the permeable bricks is improved; part of iron elements are loaded, so that the pore cleaning ability and the water permeability are improved.

Description

technical field [0001] The invention relates to a preparation method of a composite permeable brick, belonging to the technical field of building materials. Background technique [0002] At present, the floors of city squares, commercial streets, sidewalks, community activities, parking lots, etc. are mainly paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The impermeable floors are very harmful to the urban environment. When it rains, the impermeable ground completely prevents the rainwater from infiltrating directly into the ground, and the accumulated water makes it very inconvenient for people to travel; the precious water resources eventually flow away with the drainage pipes, which increases the burden on urban drainage facilities; The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetation, makes it difficult for the surface plants in the city to grow...
