Preparation method of ecological sustainable degradable material sand barrier

Abstract

The invention discloses a preparation method of an ecological sustainable degradable material sand barrier. The preparation method comprises the following steps of (1) preparing the degradable material sand barrier; (2) preparing a functional finishing liquid of the degradable material sand barrier; (3) carrying out functional finishing treatment on the degradable material sand barrier; and (4) laying the degradable material sand barrier. The degradable material sand barrier is manufactured from leftover materials in the spinning process, the raw material cost is reduced, and meanwhile, environment friendliness and degradability are achieved, the near-ground wind speed can be effectively reduced, wind erosion can be relieved, and a relatively stable and suitable environment is created for plant growth. Melamine resin is adopted as a stiffening finishing agent and ammonium dihydrogen phosphate is adopted as a catalyst, the reticular sand barrier is endowed with excellent stiffness, no stand column is needed, and manpower and material resources are reduced; and meanwhile, after the effective service life is achieved, the melamine resin and ammonium dihydrogen phosphate are converted into N and P fertilizers along with degradation of the sand barrier, and the soil fertility can be improved.

Description

technical field [0001] The invention belongs to the technical field of sand control and environmental protection, and in particular relates to a preparation method of an ecologically sustainable degradable material sand barrier. Background technique [0002] my country is the country with the largest desertification and sandification area in the world. Desertification has led to the ecological fragility of the region and restricted the economic development of the sandy region. Therefore, in desertification prevention and control, it is very important to explore the path of ecological protection and coordinated economic and social development. [0003] In recent years, my country's desertification control has achieved initial results, and the green area has gradually expanded. At the same time, with the development of science and technology, the measures for desertification control have been continuously updated and iterated, including clay sand barriers, grass grid sand barr...

Problems solved by technology

However, during the application of fiber material sand barriers, due to the need to manually shape the columns, it is time-consuming and laborious

At the same time, more chemical fiber materials are used for sand barriers, which are difficult to degrade. After the effective period, they need to be dismantled, otherwise it is not conducive to the growth and reproduction of plants.
