Description
Technical field
The present invention relates to coating research and preparation technical field, relate to petrochemical industry and steel construction is had again under the condition that can be incubated to the protective cover of preservative activity, specifically, is corrosion resistant epoxy novolac coating under a kind of thermal insulation layer.
Background technology
Global energy dilemma facilitates the research and development of power-saving technology, and power-saving technology advances the generally application of heat preservation technology in petrochemical industry, heating pipeline etc.The effect of heating pipeline thermal insulation layer blocks scattering and disappearing of hot-fluid, and its lagging material adopted is through that calcination of minerals is sticky again to be processed mostly.Owing to containing a large amount of inorganic salt in mineral, the lagging material made with mineral is still containing a large amount of corrosive deposits such as muriate, sulfide; On the other hand, described lagging material is generally vesicular structure, there are larger surface-area and abundant kapillary, thus, they have stronger adsorptive power and water absorbing properties, when rain leakage or condensation of moisture, the alkaline soluble materials such as the chlorion in thermal insulation layer form ionogen can contact steel pipeline with oxygen surface with water, cause the corrosion of heating pipeline metallic surface.Because this corrosion occurs under thermal insulation layer, be difficult to find and on-call maintenance at the initial stage of corrosion, leak until realize that heating pipeline has often to have there occurs during corrosion or cause accident.Therefore, the bore a hole massive losses that causes of the corrosion (CUI, corrosionunderinsulation) under thermal insulation layer becomes the significant problem that petrochemical industry and heating pipeline Application Areas face.In the past, for the corrosion under thermal insulation layer pay close attention to and few, but along with petrochemical industry is every year because the corrosion under thermal insulation layer causes up to tens million of massive losses, people more and more pay close attention to this problem.
At present, the anticorrosion of heating pipeline and insulation are made up of two portions system usually: first, at heating pipeline metallic surface coating corrosion protection coating; Then, corrosion protection coating adopt again lagging material carry out adiabatic heat-insulation to pipeline and equipment.Because the common working temperature of heating pipeline is higher, the limited use of common coating under thermal insulation layer, this should be: (1) common coating non-refractory, and it at high temperature easily occurs that coatingsurface bubbles and carbonization, causes coating premature failure; Some high-temperature resistant coatings due to construction coating thinner, though resistant against high temperatures, preservative effect is undesirable, just easily corrodes after short-period used.Therefore, present people have two requirements for the protective system under thermal insulation layer: one, and the resistance to elevated temperatures of coating should meet the requirement of environment; Two, coating has longer antiseptic property; Need the high temperature resistant coating combined with anti-corrosion function.
