Problems solved by technology

The seepage irrigation pipe is mostly made of rubber foaming process. In this process, if the foaming rate is low, the seepage holes formed are small and cannot meet the requirements of seepage irrigation. If the foaming rate is high, the mechanical strength of the pipe body is low, and it is even difficult to Forming, and it is easy for soil particles to enter the seepage hole to cause blockage, resulting in a short service life, frequent replacement, and increased agricultural production costs

Abstract

The invention discloses a water seepage pipe for agricultural irrigation and a preparing method thereof. The water seepage pipe comprises a water seepage pipe body and filter cloth wrapping the water seepage pipe body. The water seepage pipe body comprises, by mass, 85-90% of atactic polypropylene, 3-8% of polyvinyl chloride and 3-8% of polyethylene; the filter cloth comprises, by mass, 65-75% of polybutylene terephthalate glycol and 25-35% of isotatic polypropylene. The preparing method of the water seepage pipe is simple, in comparison with some current preparing methods for the water seepage pipe, raw materials are easy to obtain, operation is easy, the service life of the prepared water seepage pipe is longer compared with that of an existing water seepage pipe, and the effect is better.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a seepage pipe for agricultural irrigation and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and the annual irrigation water needs to consume a lot of water resources. However, my country is also a country with serious shortage of water resources. The per capita water resources are only equivalent to a quarter of the world's per capita. Water irrigation methods are of great significance to agricultural production in our country. Among many irrigation methods, seepage irrigation is considered to be the best water-saving irrigation method and the most beneficial irrigation method for crop growth. The seepage irrigation pipe is mostly made of rubber foaming process. In this process, if the foaming rate is low, the seepage holes formed are small and cannot meet the requirements of seepage irrigation. If the foaming rate ...
