Abstract

The invention discloses a salt-tolerant water-retaining agent containing minerals. The water-retaining agent is prepared from the following components in parts by weight: 2 to 4 parts of polyacrylamide; 3 to 8 parts of sodium polyacrylate; 4 to 7 parts of potassium polyacrylate; 3.5 to 6 parts of ammonium polyacrylate; 3-8 parts of volcanic ash; 3-10 parts of clay, 2-6 parts of limestone, 1.5-6 parts of rare earth, 4-8 parts of plant straws, 6-12 parts of sawdust, 1.2-1.5 parts of lignin, 1-4 parts of resin adhesive, 1.2-4.3 parts of urea, 0.8-1.8 parts of manganese sulfate, 0.6-1.5 parts of mono-potassium phosphate, 1.7-3 parts of ferric sulfate and 1.1-3 parts of zinc sulfate. The water-retaining agent is rich in minerals, can be prepared into different concentrations to neutralize different alkali-salt lands, can fully retain water in the alkali-salt lands, and is simple in overall processing method and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a mineral-containing salt-tolerant water retention agent and a preparation method thereof. Background technique [0002] The water-retaining agent uses superabsorbent resin, which is a functional polymer material with particularly strong water absorption capacity. Non-toxic and harmless, it releases and absorbs water repeatedly, so people in agriculture compare it to a "miniature reservoir". At the same time, it can also absorb fertilizers and pesticides and release them slowly to increase fertilizer and drug effects. Superabsorbent resins are widely used in agriculture, forestry, horticulture, and building materials; in industry, they can be widely used in petrochemicals, cables, papermaking, sensors, fire extinguishers, fiber products, cosmetics, food preservation, inflatable toys, etc. [0003] At present, the water-retaining agent used in the original soil ...
