Embodiment 1

[0031] A chemical sand-fixing material, which is composed of starch series binders, inorganic binders, auxiliary agents and water raw materials, and the proportion of each raw material to the total weight is:

[0032] Starch series binder (PVA grafted oxidized starch) 0.5%,

[0033] Inorganic binder (sodium silicate) 0.1%,

[0034] Auxiliary (sodium benzoate preservative) 1%,

[0035] Water 98.4%.

[0036] The preparation method of the above-mentioned chemical sand-fixing material, firstly prepare starch series binder, make starch series binder solution with weight concentration of 1.5-20% with water, and make inorganic binder with water to make weight concentration 0.2-10% inorganic binder solution; then mix the inorganic binder solution, additives and starch series binder solution, and finally add the remaining water to dilute and stir evenly to obtain the product. Spray the prepared chemical sand-fixing material on the sand surface for consolidation.

Abstract

The present invention relates to a kind of chemical sand fixing material and its preparation process. The chemical sand fixing material consists of starch adhesive 0.5-10 wt%, inorganic adhesive 0.1-5 wt%, active stuffing 0-2 wt%, chemical fertilizer 0-0.5 wt%, assistant 0.01-1 wt% and water 89-99 wt%. The starch adhesive may be raw starch adhesive, denatured starch adhesive, high molecular grafted starch adhesive or their arbitrary mixture; the inorganic adhesive is sodium silicate and / or potassium silicate; and the assistant is preservative, wetting dispersant or defoaming agent. The present invention has good sand fixing effect, can provide plant with micro growth environment, and has the features of low cost and environment friendship.

Description

technical field [0001] The invention relates to a chemical sand-fixing material and a preparation method thereof, in particular to a chemical sand-fixing material used for desertification land, including but not limited to roadbeds of transportation facilities such as desert roads and railways, and surrounding deserts, ecological restoration, and creation of an environment suitable for plant growth. Composite materials and methods for their preparation. Background technique [0002] The current technologies and materials for chemical control of land desertification mainly use the following technologies and materials: [0003] 1. Petroleum asphalt sand control technology: use crude oil, residual oil, asphalt and emulsified asphalt to spray on the surface of desertified land to form a continuous consolidation layer, which gradually hardens after evaporation, which can protect the land from wind erosion. The weather resistance of the material is poor, it is easy to age and dec...
