Description

Structural thermal insulation materials for marine engineering and preparation method thereof
Technical Field
The invention relates to a kind of structural thermal insulation material, in particular to structural thermal insulation materials for marine engineering and preparation method thereof
Background technology
At present, hose usage in ocean engineering is increasing. Ocean hoses are mainly composed of a skeleton layer, an insulation layer, an inner lining layer, a compression armor layer, a tensile armor layer and an outer sheath layer. Normally submarine pipelines transport crude oil (gas) bearing a static pressure at a certain water depth in cold ocean water environment. For some relatively high-consistency crude oils (such as waxy, colloidal and other high freezing point crude oils), if special measures are not taken during transportation, when oil temperature drops to a certain value, wax component of high molecular weight and low molecular weight will successively precipitate, viscosity of crude oil increases and its fluidity deteriorates, or in conditions of high pressure and long distance transportation of natural gas, natural gas hydrates will precipitate in a solid shape like loose ice, which may cause pipeline blockage in severe cases, causing production accidents. Therefore, it is necessary to carry out effective thermal insulation treatment to submarine pipelines to ensure regular operation of the pipelines.
Composite polyurethane and multi-layer composite polypropylene are the most important thermal insulation materials in thermal insulation work of wet pipelines in a deep seawater; solid polymer synthetic materials, foamed polymer synthetic materials, aerogels and phase change energy storage materials also have a small number of applications in tube-in-tube insulation structures. However, Technical level of domestic submarine pipeline insulation material development is relatively low, and marine insulation materials rely on importing from abroad, which is expensive, and takes long transportation time, making it urgent to develop new material for ocean oil and gas pipeline insulation, to satisfy demand of domestic deep ocean water oil and gas development.
