Abstract

The invention discloses a preparation method of water-diverting coating fiber and belongs to the technical field of water retention material preparation. A binder adopted in the method is a tree-shaped water-soluble polymer, a large amount of free water can be absorbed for storage through the highly cross-linked three-dimensional network structure of the water-soluble polymer and a large number ofhydrophilic groups on its macromolecular chains, the spatial network structure of a coating material is effectively improved, and the moisture absorption and coating effect of the material is effectively improved through water permeability and film-forming property of a modified swelling material. The pore diameter of the material is effectively increased through a hollow palm fiber material witha molecular sieve structure, coated with coating film and having water permeability and homogeneous interlayer spacing, pore diameter distribution of the coating material is improved, the material isfully bonded with the binder with the three-dimensional network structure, and the water diversion performance of the material is improved.

Description

technical field [0001] The invention discloses a method for preparing a water-conducting coating fiber, which belongs to the technical field of water-retaining material preparation. Background technique [0002] Global desertification is becoming more and more serious, which has caused more than 1 billion people to be affected. Since the 1950s, the area of ​​desertification in my country has been expanding. From the mid-1980s to the mid-1990s, it reached 2460 km2 per year, which is equivalent to engulfing the land area of ​​a medium-sized county every year. In the late 1990s, the expansion rate continued unabated. According to statistics from remote sensing data, the area of ​​desertified land in my country is increasing at an average annual rate of 2100 km2, involving 470 counties (cities, banners) across the country. The fundamental way to control desertification is ecological restoration, and the key factor of ecological restoration is water condition. However, in desert...
