Abstract

The invention discloses a glass fiber impregnating agent for a glass fiber reinforced plastic pipeline and a preparation method and device, and belongs to the technical field of glass fiber impregnating agents. The impregnating agent comprises 5-13% of a coupling agent, 15-30% of a lubricant A, 0.5-3.0% of a lubricant B, 49-72% of a film-forming agent, 1-8% of an antistatic agent, 1-5% of a pH regulator, and the balance being water, wherein the solid mass of the impregnating agent accounts for 3.5-7.5% of the total mass of the impregnating agent, and the coupling agent is an enhanced silane coupling agent. The lubricant is a mixture of a lubricant A and a lubricant B, the lubricant A is a polyoxyethylene ether lubricant, the lubricant B is a quaternary ammonium salt lubricant, the film-forming agent is a mixture of two different types of epoxy emulsions, namely a film-forming agent A and a film-forming agent B, the antistatic agent is an ammonium salt antistatic agent, and the pH regulator is an organic acid; the prepared impregnating agent is excellent in performance, the quality of a glass fiber product can be improved, a processed glass fiber reinforced plastic pipeline has thecomprehensive performance of excellent mechanical strength and high pressure resistance, the short-time failure pressure of the glass fiber reinforced plastic pipeline is improved, and the market requirements are met.

Description

technical field [0001] The invention belongs to the technical field of glass fiber sizing agent, and in particular relates to a glass fiber sizing agent for FRP pipelines, a preparation method and a device. Background technique [0002] High-pressure oil pipes are pressure-resistant pipes required in the process of oil collection and transportation, and are generally made of steel and glass fiber reinforced plastics. At present, major domestic oil fields have successively experienced secondary oil recovery and tertiary oil recovery, and oil production has entered a period of high water content or ultra-high water content development. The water contains a large amount of corrosive substances, and high water content leads to higher and higher corrosiveness of the transported liquid. This puts higher and higher requirements on the corrosion resistance of the pipeline; in accordance with the requirements of 6.3.2 and 6.3.3 of "High Pressure FRP Oil Pipes for the Oil and Gas Indu...
