Low corresion fire retardant polyurethane composition material and its manufacturing method

Abstract

The low corrosion fire retardant heat insulating polyurethane composition material includes two components, component A and component B. The component A consists of polyether polyol, cyclohexane, silicone oil, potassium acetate, dimethylethanolamine, 2, 4, 6-tri(dimethylaminomethyl) phenol, water, monofluoro trichloroethanone, trichloroethyl phosphate and silicate hydrate; and the component B is isocyanate. When the composition material is used, the component A and the component B are mixed to form the foamed heat insulating polyurethane material with low corrosion, high fire retarding performance and simple production process. The foamed heat insulating polyurethane material is used for oil and gas pipeline.

Description

technical field [0001] The invention relates to a low-corrosion flame-retardant polyurethane composite material and a manufacturing method, which are used for thermal insulation of oil and gas gathering and transportation pipelines. Background technique [0002] The existing polyurethane foam heat preservation pipelines seep water due to cracks at the joints, and the polyurethane foam material will precipitate acidic medium when it encounters water, which will corrode the steel pipelines and reduce the service life of the pipelines. The flame retardancy of the existing polyurethane foam insulation material is not good and needs to be further improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-corrosion flame-retardant product with simple production process, reasonable price, excellent thermal insulation performance, reduced corrosion, and improved flame retardancy by avoiding the shortcomings of the a...
