Embodiment 1

[0029] As the basic embodiment of the present invention, the present invention includes a water purification granule for concrete, comprising granules with purification function and a starch film on the outer surface of the granule with purification function, and the starch film is 5% by mass fraction. The starch film solution is sprayed on the outer surface of the granule with purification function and then dried, and the starch film solution is obtained by dissolving modified starch in a solvent.

[0030] Among them, the particles with purification function are preferably molecular sieves. The modified starch is obtained through esterification and modification of corn starch, and the solvent is 1,4-dioxane.

[0031] The preparation method of the water purification particles is as follows:

[0032] a. Clean the molecular sieve and dry it at 105°C, then cool it to room temperature;

[0033] b. Dissolving the modified starch in 1,4-dioxane to obtain a starch film solution wit...

[0045] Among them, the particles with purification function are preferably fruit shell activated carbon. The modified starch is obtained through esterification and modification of potato starch, and the solvent is dichloromethane.

[0046] The preparation method of the water purification particles is as follows:

[0047] a. Clean the shell activated carbon and dry it at 105°C, then cool it to room temperature;

[0048] b. Dissolving modified starch in methylene chloride to obt...

Embodiment 3

[0059] As a preferred embodiment of the present invention, the present invention includes a water purification granule for concrete, comprising granules with purification function and a starch film on the outer surface of the granule with purification function, and the starch film has a mass fraction of 15 % starch film solution is sprayed on the outer surface of the granule with purification function and then dried, and the starch film solution is obtained by dissolving modified starch in a solvent.

[0060] Among them, the particles with purification function are preferably walnut shells. The modified starch is obtained through esterification and modification of tapioca starch, and the solvent is chloroform.

[0061] The preparation method of the water purification particles is as follows:

[0062] a. Clean the walnut shells and dry them at 105°C, then cool to room temperature;

[0063] b. Dissolving modified starch in chloroform to obtain a starch film solution with a mas...

Abstract

The invention relates to the technical field of building materials and in particular to a water purifying particle for concrete and a preparation method thereof. The water purifying particle comprisesa particle with a purifying function and a starch membrane positioned on the outer surface of the particle with the purifying function. The preparation method for the water purifying particle comprises the following steps: after washing the particle with the purifying function clean, drying, and cooling to room temperature; enabling modified starch to be dissolved in a solvent, to obtain starch membrane solution of which a mass fraction is 5%-15%; uniformly spraying the starch membrane solution on the outer surface of the particle with the purifying function, performing rapid drying treatment, forming the starch membrane, and preparing the water purifying particle. The water purifying particle is capable of, while applied to the concrete, effectively solving problems in the prior art thatthe concrete is easily blocked, service life is short and the like, improving a porosity of the concrete, and has lasting good water permeability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-purifying granule for concrete and a preparation method thereof. Background technique [0002] Sponge city construction follows the principle of ecological priority and combines natural approaches with artificial measures. On the premise of ensuring the safety of urban drainage and waterlogging, it maximizes the accumulation, infiltration and purification of rainwater in urban areas, and promotes the utilization of rainwater resources and ecological protection. environmental protection. Permeable concrete is an important part of sponge city construction. In order to better improve groundwater quality and improve drinking water quality, ecological concrete with water purification function came into being. However, the existing permeable concrete pavement has the defects of insufficient decontamination ability and low strength. [0003] In the prior art, a Chin...
