Fiber reinforced thermoplastic compound pipeline and manufacturing technology thereof

Abstract

The invention discloses a fiber reinforced thermoplastic compound pipeline and a manufacturing technology of the pipeline. The compound pipeline comprises an inner lining layer, a fiber reinforced layer and an outer surface layer. The inner lining layer and the outer surface layer are made of the same material comprising, by weight, 170-180 parts of polypropylene, 20-28 parts of polytetrafluoroethylene, 10-12 parts of linoleic acid, 3-4 parts of dibutyltin maleate, 4-6 parts of barium stearate, 2-3 parts of wollastonite, 5-7 parts of white carbon black, 1-3 parts of barium sulfate, 7-9 parts of alkyl phosphoric acid, 3-5 parts of ethylene propylene rubber, 5-7 parts of glyceryl monostearate, 6-8 parts of silane coupling agents, 4-5 parts of dioctyl adipate, 2-3 parts of phosphite antioxidants, 4-6 parts of titanium oxide fine powder and 10-12 parts of assistant master batches. The pipeline has high tensile strength, bending strength, modulus and impact resistance. The manufacturing method of the pipeline is simple and easy to operate, and pipes of different specifications and with different function can be manufactured to meet social requirements through different pipe moulds.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a fiber-reinforced thermoplastic composite pipe and a preparation process thereof. Background technique [0002] With the continuous expansion of cities and the continuous extraction of oil and natural gas, the demand for transportation pipelines is also increasing. Traditional steel pipelines have poor corrosion resistance and are not easy to handle, so they can no longer meet the current needs; especially in the oil transportation industry, due to the high viscosity of oil, it is necessary to build heating tanks every few kilometers to heat the pipeline during transportation. Raising the temperature of oil can improve the fluidity of oil and ensure the smooth transportation of oil, but this will undoubtedly lead to high transportation costs. At the same time, my country's main oil and natural gas are mostly distributed in deserts, swamps or mountainous a...

Problems solved by technology

Traditional steel pipelines have poor corrosion resistance and are not easy to handle, so they can no longer meet the current needs; especially in the oil transportation industry, due to the high viscosity of oil, it is necessary to build heating tanks every few kilometers to heat the pipeline during transportation. Raising the temperature of oil can improve the fluidity of oil and ensure the smooth transportation of oil, but this will undoubtedly lead to high transportation costs

At the same time, my country's main oil and natural gas are mostly distributed in deserts, swamps or mountainous areas, and the natural environment is relatively harsh. When laying steel pipelines, it is seriously affected by the natural environment, and due to ground subsidence, landslides and other reasons, the pipelines are extremely prone to damage. Phenomenon
