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.
