Embodiment 1

[0017] Taking the manufacture of anti-static epoxy FRP pipes with a diameter of 1000mm, a pressure of 1.8Mpa and a length of 3000mm as an example, carbon fiber lining felt, high-strength carbon fiber, glass fiber and imported epoxy resin are used as raw materials, winding molding, computer control operation, steam Heating in stages, high temperature internal mold curing. The specific process is as follows:

[0018] 1. Material preparation: Prepare 28 rolls of high-strength glass fiber, about 16 kg per roll; 50 kg of epoxy resin; 45 kg of curing agent; 5 kg of accelerator; one roll of carbon fiber felt, 8 kg per roll (width is not limited); 2 high-strength carbon fibers, weighing 6kg; after the raw materials are prepared, pour epoxy resin, curing agent, and accelerator into the mixing tank for stirring. The stirring time is 10 minutes, and the speed is 200 rpm to obtain a well-stirred ring. Oxygen resin mixture 110kg, pour the stirred mixture into the bucket for subsequent use...

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...
