Description
Technical field
The present invention relates to high-temperature resistant anti-corrosive field of heat insulating materials, be specifically related to a kind of pipelines and petrochemical pipelines normal temperature solidified high-temperature resistant anti-corrosive insulation material and preparation method thereof and application.
Background technology
At present in the oil refining industry of China, the safeguard procedures of equipment and pipeline are made up of typical " anticorrosive coat+heat insulation layer+overcoat ".Anticorrosive coat is general anti-corrosion primer；Heat insulation layer is traditional rock wool fibers or aluminium silicate volume felt etc., and this material water absorption rate is high, and many genotypes material, seam are many, generally have 10-20cm thick；Overcoat is diameter is galvanized iron sheet or the aluminum skin of 1-2m.Actual petrochemical equipment and pipeline often ratio comparatively dense, traditional syllogic safeguard procedures not only bring very big inconvenience to construction；And this heat insulation system is not easily coated with at the elbow of pipeline, interface, valve place so that it is exposed in atmosphere, be more subject to corrosion, heavy damage heat insulation effect.Corrosion not only causes huge economic loss, bring many hidden danger to safety in production simultaneously, especially petroleum cracking equipment, high-temperature reaction equipment and pipeline have the feature of the corrosive medium of high temperature, high pressure and complexity, and equipment corrosion Resolving probiems is bad will have a strong impact on normal production；Relevant information shows simultaneously, and the energy lost because of heat dissipation of pipeline every year accounts for 30% that petrochemical industry always consumes energy, and the corrosion-resistant thermal insulation work therefore carrying out pipelines and petrochemical pipelines especially high-temperature service and pipeline is most important.
Film formation resin is with Si-O-Si main chain for basic cell structure, and side chain is by Si atom and other various organic groups, as the polycondensation such as methyl, phenyl forms.This special structure, gives the performance of the many excellences of film formation resin, for instance good cementability, excellent solvent resistance and anti-corrosive properties, lasting weatherability, splendid heat-resisting quantity and normal temperature solidified property.Why high temperature resistant this material is, and the bond energy being because film formation resin backbone Si-O-Si is significantly larger than the bond energy of side base C-C key and C-O key, continuous rising along with temperature, side-chain radical in film formation resin such as methyl, phenyl are decomposed gradually, volatilization, when temperature is more than 400 DEG C, two-step film forming powder melts gradually and interacts with the Si-O-Si main chain of film formation resin, film forming again, form new high temperature resistant disilicide layer, i.e. high temperature " two-step film forming " mechanism.Therefore in film formation cold coating, add two-step film forming powder can apply to petrochemical equipment and the pipeline of 500 DEG C of high temperature above.
Air heat insulation filler microballon macroscopically white powder, belongs to soda lime borosilicate glass material.Being the nature of glass spheroid of many thin-walleds, closing, hollow on microcosmic, ball interior wraps up a certain amount of gas, and spheroid size differs.Due to its inner hollow, parcel gas, therefore there is light weight, the feature such as heat conductivity is low, anti-pressure ability is strong, excellent in stability；Spheroid size can not form mutually supplementing on particle diameter first so that cenosphere application has the feature rationally plugged the gap in the composite；Heat conductivity is low makes this applying filler in composite, it is possible to give the heat-insulating property that material is excellent.In sum, air heat insulation filler joins the heat-insulating property that can be greatly increased this material in film formation resin.
