[0003] The Chinese invention patent with the publication number CN108373281A discloses a method for manufacturing anti-seepage air sand. The invention obtains air-permeable anti-seepage sand by drying the sand, mixing it with a treatment agent, and standing still. The process is short and the production cost is low. , suitable for large-scale and centralized production, but the anti-seepage performance of the anti-seepage air sand obtained by this scheme still does not meet the requirements when it is used, and it is easy to lose after being washed by rainwater
The Chinese invention patent with publication number CN103563600A discloses a production method of air-permeable and anti-seepage sand, which can reduce the water permeability of sandy soil, reserve enough water for plants, and significantly improve the survival rate of seedlings, but its technical scheme is complicated. The obtained anti-seepage sand has poor comprehensive mechanical properties and short service life, so it is necessary to improve
On the other hand, the existing ordinary air-permeable and anti-seepage sand has high fluidity. When it is laid and used on a construction surface with a slope, the air-permeable and anti-seepage sand will flow downward, which is not easy to construct and will easily lead to engineering quality problems. When it exceeds 30 degrees, it is basically impossible to construct

Abstract

The invention relates to the technical field of breathable and anti-seepage materials, in particular to a breathable and anti-seepage sand and a preparation method thereof. The breathable anti-seepage sand includes the following components by mass fraction: 90-95% of raw sand, 0.5-1% of modified glass fiber, 0.5-1% of fluorosilicon surfactant, 0.2-1% of sodium bentonite, diatomite Powder 0.3‑1%, attapulgite clay powder 0.2‑1%, white carbon black 0.3‑1%, paraffin wax 2‑6%. The air-permeable and anti-seepage sand of the invention can reduce the water permeability of the soil and improve the air-permeability of the soil, has good bonding performance, is not easily washed away by rainwater, has excellent corrosion resistance and acid resistance, and has a long service life. During the preparation process, the mixed and synergistic effect of various materials can further improve the anti-seepage effect of the breathable anti-seepage sand. The method of batch mixing can effectively prevent the agglomeration of the mixed materials. Adding paraffin wax in two successively can ensure that the paraffin wax and The materials are fully mixed to further improve the bonding performance of the breathable anti-seepage sand.

Description
