Novel offshore platform thermal insulation pipeline outer protection material, preparation method thereof and thermal insulation pipeline outer protection layer

Abstract

The invention provides a novel offshore platform thermal insulation pipeline outer protection material. The novel offshore platform thermal insulation pipeline outer protection material is prepared from the following raw materials in parts by weight: 20 to 40 parts of modified epoxy resin, 0.08 to 0.35 part of photoinitiator UVI16992, 0.1 to 0.5 part of a wetting agent, 0.2 to 0.5 part of a magnesium oxide paste, 10 to 26 parts of glass fibers, 10 to 50 parts of aluminum hydroxide, 10 to 20 parts of quartz powder, 1 to 10 parts of inorganic salt whisker and 1 to 2 parts of KH550. A thermal insulation pipeline outer protection layer prepared from the protection material can effectively slow down the phenomenon of CUI, is particularly suitable for offshore platform thermal insulation pipeline outer protection layers, and has the characteristics of resistance to treading deformation, impact resistance, good sealing property and the like.

Description

technical field [0001] The invention belongs to the field of outer protective layers of thermal insulation pipelines on offshore platforms, and in particular relates to a novel outer protective material for thermal insulation pipelines on offshore platforms, a preparation method thereof, and an outer protective layer of thermal insulation pipelines. Background technique [0002] Corrosion under the insulation layer of pipelines or equipment is often caused by the damage of the outer protective layer due to installation, operation, performance or external factors during the use of the insulation material and the outer protective layer (usually aluminum foil or stainless steel). The local area between the material and the base metal forms a corrosive environment, leading to the occurrence of corrosion under insulation (CUI). Corrosion under insulation is more severe on pipe or equipment surfaces that are not coated or that are exposed to corrosive industrial atmospheres. For ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, it is very necessary to propose a better-performing insulation pipeline outer defense layer, which can not only slow down the CUI phenomenon, but also effectively prevent the existing protection layer from being easily trampled, deformed, impacted and not tightly sealed.
