Abstract

The invention discloses a filter material surrounded corrugated pipe for saline-alkali soil, which is prepared from the following components in parts by weight: 65-70 parts of polyvinyl chloride resin, 0.1-0.5 part of acrylate, 0.5-1.2 parts of silane coupling agent KH-550, 1-2 parts of nano zinc oxide, 0.5-1.5 parts of barium stearate, 1-2 parts of calcium aluminum borosilicate, 0.8-1.5 parts ofsodium acetate, 2-3 parts of glycerol triacetate, 0.2-0.6 part of butylene glycol laurate, 1-3 parts of neopentyl glycol diheptanoate, and 0.5-1.5 parts of ethyl hexyl triazinone. The filter materialsurrounded corrugated pipe for saline-alkali soil provided in the invention is high in compression strength, good in low-temperature toughness, not prone to aging, and also high in saline-alkali tolerance.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land treatment, in particular to a filter wave tube for saline-alkali land and a preparation method thereof. Background technique [0002] Land salinization is one of the main problems of land degradation in the world today. In my country, it is mainly distributed in the North China Plain, Northeast Plain, northwest inland areas and coastal areas. The generation of saline-alkali land makes it difficult to use large areas of soil resources, and the comprehensive agricultural production capacity decreases. Saline-alkali soil refers to the general term of soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. It is alkaline, the content of organic matter in saline-alkali soil is low, the soil fertility is low, the physical and chemical properties are poor, there are many anions ...
