example 1

[0024] According to the mass ratio of 1:1, mix the sodium chloride solution with a mass fraction of 30% and ammonium bicarbonate and put it into a beaker, then put the beaker into a water bath, heat up to 40°C, stir for 30 minutes, and filter and separate to obtain Filter residue: put the above filter residue into a crucible, then move the crucible into a heating box, heat up to 80°C, and keep it warm for 1 hour. After the reaction, mix the reaction product and water in the crucible in an equal mass ratio to obtain a self-made modification solution; Weigh the aeolian sand and put it into the ball mill, and add zirconia ball milling beads into the ball mill tank according to the mass ratio of the ball to material at 20:1, ball mill and pulverize for 40 minutes, and pass through a 100-mesh sieve to collect the sifted powder, and sieve the sifted powder and The above-mentioned self-made modified liquid is mixed according to a mass ratio of 1:8, then put into an ultrasonic oscillat...

Abstract

The invention relates to the technical field of preparation of building materials, in particular to a preparation method of impervious and permeable sand. In the method, wind-piled sand is taken as araw material, sodium chloride is reacted with ammonium bicarbonate and water to obtain a modified solution, pretreated wind-piled sand is obtained by impregnation of the wind-piled sand with the modified solution, the pretreated wind-piled sand is reacted with hydrochloric acid, and finally, a filter cake is reacted with anhydrous methanol, red phosphorus and iodine at high temperature and pressure to obtain the impervious and permeable sand. Sodium chloride is reacted with ammonium bicarbonate to generate sodium bicarbonate low in solubility, the sodium chloride solution serves as the modified solution, the porous wind-piled sand is soaked, soaked wind-piling sand is reacted in heat, and pore structure inside the wind-piled sand is enlarged; the wind-piling sand is reacted with hydrochloric acid, so that the wind-piling sand is high in hydrophobicity, methyl iodide is reacted with active hydroxyl grouped on the surface of the wind-piling sand under high temperature and pressure to further improve hydrophobicity of the wind-piling sand, and broad application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a preparation method of anti-permeation air sand. Background technique [0002] China is a country seriously short of water. More than half of the land has an average annual rainfall of less than 600 millimeters, and the per capita water resources are less than a quarter of the global average. Especially in the central and western regions, the climate is dry and the rainfall is low. It is also plagued by water shortages, which seriously restricts the development of the local economy. [0003] Windbreak and sand fixation is a job handed down from generation to generation by the people living in the vast west of my country. When planting trees, a lot of trees are planted every year, but not many trees will survive in the coming year, and the only remaining saplings are only enough to survive and cannot grow luxuriantly. The reason is that most of the land in ...
