Preparation method of anti-corrosion and anti-impact PE composite pipe

Abstract

The invention discloses a preparation method of an anti-corrosion and anti-impact PE composite pipe. The anti-corrosion and anti-impact PE composite pipe comprises polyethylene, color master batches, ceramic particles, a compatibilizer, rare earth porcelain sand, a polyolefin fiber fabric and a filler, the content of the polyethylene is 70%-90%, the content of the color masterbatch is 1%-2%, the content of the ceramic particles is 3%-7%, the content of the compatibilizer is 0.5%-0.8%, the content of the rare earth porcelain sand is 1%-3%, the content of the polyolefin fiber fabric is 10%-20%, the content of the lubricant is 1%-10%, the content of the filler is 10.5%-15%, and the content of the filler is 5%-20%. According to the preparation method of the anti-corrosion and anti-impact PE composite pipe, the wall thickness of the pipe body is adjusted for production, in a severe environment, the thickness of the pipe wall is about large, the anti-corrosion degree is higher, meanwhile, the anti-impact degree is also increased, and due to the use of the polyolefin fiber fabric and the ceramic particles of different components, the anti-corrosion and anti-impact PE composite pipe can be better manufactured. The corrosion resistance and the impact resistance of the pipe body are more effective.

Description

technical field [0001] The invention relates to the technical field of PE composite pipes, in particular to a preparation method for anti-corrosion and impact-resistant PE composite pipes. Background technique [0002] PE composite pipe refers to the composite of multi-layer materials, of which PE material accounts for the main component, including steel mesh skeleton PE pipe, double hot-melt steel-plastic composite pressure pipe, perforated steel strip PE pipe, plastic-coated steel-plastic pipe inside and outside, etc. Therefore, PE composite pipe is the general name of the pipe body containing PE material in the composite material. [0003] In existing applications, PE composite pipes are used in a wide range of applications in every corner of life. As a frequently used PE pipe, some defects are gradually exposed. For example, the actual application environment is more complicated. Under long-term use, the pipe body is susceptible to corrosion by the liquid in the pipe an...

Some also believe that the anti-corrosion performance of the three-layer PE anti-corrosion layer can mainly depend on the FBE layer, while the PE layer mainly plays the role of mechanical protection; the reason is that when the PE layer is used, the mechanical properties of the anti-impact surface of the anti-corrosion layer are enhanced, which is convenient. Anti-corrosion pipes are backfilled during transportation, construction and burial, but under the action of temperature changes or environmental stress, once the PE layer cracks, the corrosive medium will directly corrode the steel pipe body, which is still inconvenient to use
