Problems solved by technology

However, there is still a large amount of irrigation water leaking during use, and it can only retain water, but not save water. This is limited in large-scale application in arid areas with severe water shortages.
At the same time, due to raw materials, cost, technology and other issues, super absorbent resin has not yet been mass-produced, so the application range cannot be effectively expanded.
[0004] At present, the superabsorbent resin used for desert planting in my country mainly adopts imported materials, so the high cost is not suitable for large-scale promotion and application, especially in most desertified areas in my country, it is impossible to popularize and use it in poor counties, and the production of domestic superabsorbent resin is still under development stage, large-scale production cannot be formed in the short term, and it also involves production cost issues

Abstract

The water-preserving agent for desert zone is made of inorganic powder material and coupling agent according to the weight ratio of 100:0.5-2.5, the described inorganic powder body material is any one of calcium carbonate, magnesium carbonate, talcum powder, pottery clay, wollastonite, coal gangue, flyash, diatomaceous earth or desulfurized gypsum or their any combination, and the described coupling agent is any one of coupling agent of organic titanate, RCA modifying agent, aluminate coupling agent, phosphate coupling agent or silane coupling agent.

Description

1. Technical field [0001] The invention relates to anti-seepage materials used in deserts and soil erosion, in particular to production and use methods of desert water-retaining agents. 2. Background technology [0002] In the prior art, CN1161316 "Water-absorbing and water-retaining agent and its production method" discloses moisturizing products and production methods mixed with acrylic acid, ammonia water, sodium oxychloride, etc.; The water retaining agent composed of acrylic acid, alkali, crosslinking agent and initiator and its preparation method are disclosed. These methods all have defects such as high cost of raw materials. [0003] At present, to solve the problem of survival rate of afforestation plants in desertification areas at home and abroad, super absorbent resins are mainly used. The resin has two characteristics: 1. High water absorption rate, which can absorb water thousands of times its own weight in a short time; 2. Slowly release the absorbed water. ...
