preparation example Construction

[0022] The preparation method of the described environment-friendly stain-resistant sponge brick comprises the following steps:

[0023] S1: Mix cement, aggregate, and medium sand with water (water-material ratio 0.6) to obtain the base material;

[0024] S2: Add Additive A and Additive B to the base material prepared in step S1 for mixing. After mixing and stirring evenly, the material is vibrated and pressurized at 20MP to form, demolded, painted with paint, and naturally cured for 27 days to obtain a brick body ;

[0025] S3: The brick body prepared in step S2 is coated with a stain-resistant paint, and left to stand at room temperature for 24 hours to obtain an environmentally friendly stain-resistant sponge brick.

[0026] The additive A includes the following raw materials in parts by weight: 5-8 parts of ferrous sulfate, 4-5 parts of magnesium fluorosilicate, 8-12 parts of sodium silicate, and 8-15 parts of porous calcium phosphate.

Abstract

The invention discloses a preparation method of an environment-friendly stain-resistant sponge brick. The preparation method comprises the following steps: adding water into a mixture of cement, a aggregate and middle sand, and carrying out mixing by stirring to obtain a base material; then adding an additive A and an additive B into the prepared base material for mixing, carrying out vibration compression molding on the material subjected to uniform mixing and stirring, carrying out demolding, carrying out coating with pigment, and naturally carrying out curing for 27 days to prepare a brickbody; and then coating the prepared brick body with a stain-resistant coating, and carrying out standing for 24 hours at normal temperature to obtain a finished product of the environment-friendly stain-resistant sponge brick. The additive A comprises the following raw materials: ferrous sulfate, magnesium fluosilicate, sodium silicate and porous calcium phosphate, and the additive B comprises thefollowing raw materials: polypropylene (PE) fibers, polybutenoic acid, 1-boc-3-(amino)azetidine, 2,2-di-(tert-butyl peroxy)propane and disodium laureth sulfosuccinate. The environment-friendly stain-resistant sponge brick provided by the invention can be used for constructing sponge cities, is environmentally friendly, and is resistant to stain, and meanwhile, soil humidity can be kept.

Description

【Technical field】 [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a preparation method of an environment-friendly and stain-resistant sponge brick. 【Background technique】 [0002] With the rapid development of urbanization and urban construction, my country is facing a series of serious ecological problems such as urban rain and flood, urban waterlogging, smog pollution, water system pollution, water resource shortage, groundwater depletion, and loss of aquatic habitats. In order to solve outstanding problems such as urban waterlogging and the decline of urban groundwater levels, the state has proposed important measures such as the construction of sponge cities, and the construction of sponge cities requires a large number of permeable and water storage materials. At the same time, the construction of sponge cities also requires products with a certain beautifying effect on the appearance of bricks. Among th...
