Processing process of large-diameter anti-static fiber glass epoxy plastic pipeline

Abstract

The invention provides a processing process of a large-diameter anti-static fiber glass epoxy plastic pipeline. The process is characterized in that a carbon fiber felt is uniformly wound on a pipeline die, so that the carbon fiber felt is flatly coated on the outer wall of the pipeline die; after the carbon fiber felt is immersed by epoxy resin, fiber glass high-strength yarns and carbon fiber yarns are spirally wound on the pipeline die, and an anti-static high-strength fiber glass epoxy plastic pipeline produced by high-temperature cure heating after the winding is completed; and in the processing process, the carbon fiber inner felt, the high-strength carbon fiber, the fiber glass and imported epoxy resin are used as raw materials, and wounding formation, steam heating by stages and high-temperature inner die curing formation are adopted. The process comprises the following specific steps: preparing materials; winding the carbon fiber felt; adding carbon fibers; heating with steam by stages; curing and forming; and processing and finishing, thus obtaining a finished product pipeline. The pipeline provided by the invention has the advantages that the anti-static performance, the physical strength index of the material and the anti-corrosion index are not reduced at an environmental temperature of minus 40-120 DEG C, and the anti-static, anti-aging and anti-fatigue service life is not lower than 30 years under the condition that the pipeline is exposed in the sea.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastics. Background technique [0002] This pipeline is mainly used in offshore oil production platforms and ships: ballast pipeline system, fire prevention water supply system, sprinkler system, brine water supply system, cargo oil loading and unloading system and other fields. Because of the characteristics of anti-static, corrosion resistance, high strength, light weight, easy installation and long service life, marine FRP pipes have replaced metal pipes in marine engineering and shipbuilding, and have a broad prospect of use. [0003] At present, there is no precedent for the production of large-diameter anti-static epoxy glass steel pipes (with a diameter of 1 meter and a working pressure of 1.8Mpa). The current processing technology is as follows: resin: curing agent: anti-static material (powder) according to the ratio of 1:0.9 : The ratio of 0.1 is made into a mixture, whi...
