Embodiment 1
[0039] 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 5 % 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.
[0040] 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.
[0041] The preparation method of the water purification particles is as follows:
[0042] a. Clean the molecular sieve and dry it at 105°C, then cool it to room temperature;
[0043] b. Dissolving the modified starch in 1,4-dioxane to obtain a starch film solution wi...
