Abstract

The invention relates to a lignin sand-fixing agent suitable for the prevention and control of collapsing hillock erosion, which is made of the following components in parts by weight: 55-65 parts of composite binder, 18-20 parts of reinforcing agent, 15-17 parts of water-retaining agent and 5-7 parts of dispersant; the composite binder is formulated by weight parts of 15-27 parts of modified acidic lignin, 15-27 parts of modified alkaline lignin and 25-30 parts of polyacrylamide, The modified lignin sand-fixing agent is suitable for collapsing erosion areas, using sulfonated and modified lignin as the main raw material, and the lignin sand-fixing agent made not only has the sand-fixing, anti-erosion and anti-disintegration properties of general sand-fixing agents In addition, it can also maintain the original ecological environment of the soil.

Description

technical field

[0001] The invention belongs to the technical field of soil and water conservation engineering materials, and in particular relates to a lignin sand-fixing agent suitable for erosion prevention and control of collapsed hillocks. Background technique

[0002] Collapsing hillside is a phenomenon of water and soil erosion caused by soil and rocks on hillsides and erosion. It is widely distributed in southern my country, causing serious damage to cultivated land and reducing farmland production. Serious erosion of hillside collapse can also easily lead to geological disasters. The difficulty in the control of collapsed hillock erosion lies in the high content of coarse particles and the poor water retention of the soil, which leads to the fact that the soil in the collapsed hillock erosion area is easily disintegrated and the vegetation is not easy to grow and develop, so that the collapsed hillock erosion is difficult to recover naturally. In addition, there are...
