Abstract

The invention discloses an organic fiber PVC (Polyvinyl Chloride) multilayered composite flexible pipe and a preparation method thereof, aiming at solving the technical problems of a pipe for agricultural irrigation in the prior art that the corrosion resistance is poor, the toughness and the tensile strength are poor, the anti-cracking performance and the anti-freezing performance are poor, and the price is high. The organic fiber PVC multilayered composite flexible pipe comprises a pipe body, wherein a polyvinyl chloride plastic coating layer is arranged on the inner wall of the pipe body, and a composite plastic film layer is arranged on the plastic coating layer; the pipe body is made of the following raw materials in parts by weight: 28-33 parts of polyacrylonitrile fibers, 8-12 parts of liquid-state silica gel and 3-7 parts of liquid-state PVC stabilizing agent. The pipe has very remarkable advantages in the aspects of cracking strength, acid and alkali resistance, low-temperature resistance and cracking elongation and is a very ideal irrigation and water conveying pipe; mechanized construction is convenient to realize and the working efficiency is improved; the pipe is convenient to operate and maintain in a water conveying and irrigation process and is convenient to repair, and the reliable water supply is ensured.

Description

technical field [0001] The invention relates to the technical field of production of pipes for agricultural irrigation, in particular to an organic fiber PVC multilayer composite flexible pipe and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and agricultural irrigation water accounts for more than 70% of the total water consumption. It is a very urgent task for farmland irrigation to realize precise irrigation, save agricultural water resources, and increase agricultural output in irrigation areas. Pipeline irrigation is one of the important technologies to realize agricultural water-saving irrigation. Pipelines are the main components of low-pressure water delivery irrigation systems. Generally speaking, pipeline irrigation can save water by 15% to 30%. However, pipeline investment accounts for 60% to 70% of the total investment in irrigation projects. In addition, pipeline water delivery projects require high con...
