Abstract
The invention discloses a thermal insulation asphalt anticorrosion paint, which consists of isocyanate, polyether, an epoxy resin, phosphorous acid, coal tar pitch, methylbenzene, a thermal insulation material and a solvent, wherein the isocyanate is polymethylene polyphenyl isocyanate No.400, the solvent is dimethylbenzene, and the thermal insulation material consists of 50 to 80 portions of hollow glass fine powder and 80 to 100 portions of expanded perlite powder. The anticorrosion paint has the characteristics of thin coatings, low cost, time-saving and labor-saving coating, good thermal insulation performance, firm adhesion force, strong friction force resistance, resistance to chemical corrosion of acid, alkali and salt and so on.
Description
Technical field
The present invention relates to a kind of antifouling paste, particularly relate to a kind of heat insulation asphalt anticorrosion paint, belong to the macromolecular compound category.
Background technology
Be used for petroleum storage tanks, the used antifouling paste of pre-buried pipeline of industries such as petrochemical industry, metallurgy at present, kind is more, and great majority do not have a heat insulation function, and what have also exists defectives such as poor, not ageing-resistant, the easy foaming be full of cracks of weathering resistance and cycle be short.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art,, provide a kind of heat insulation asphalt anticorrosion paint by improving prescription, this antifouling paste is a macromolecular compound, has adiabatic function, firm adhesion, anti-wear power is strong and anti-impact force is big, chemical corrosions such as acid-and base-resisting, salt.
Technical solution of the present invention is: this heat insulation asphalt anticorrosion paint, be characterized in constituting by isocyanic ester, polyethers, Resins, epoxy, phosphoric acid, coal tar pitch, toluene, thermal insulation material and solvent, wherein isocyanic ester is polymethylene multi-phenenyl isocyanate 400#, solvent is a dimethylbenzene, thermal insulation material is made up of 50-80 parts the fine powder of hollow glass, 80-100 parts swelling perlite powder
The parts by weight of each constituent are:
Polymethylene multi-phenenyl isocyanate (PAPl) 400 # 20～40,
Phosphoric acid 0.01～0.03, polyethers 3～8, Resins, epoxy 4～6,
Coal tar pitch 50～60, toluene 10～15, thermal insulation material 50～150
Dimethylbenzene 60～70.
The preparation process of this heat insulation asphalt anticorrosion paint that the present invention provides is:
Earlier polymethylene multi-phenenyl isocyanate (PAPl) 400# is dropped in the reactor, add phosphoric acid and carry out emulsification, heat up while feeding intake, add polyethers again, solvent and Resins, epoxy, when carrying out reacting by heating to 80 ℃, drop in the reactor successively coal tar pitch, toluene, the fine powder of hollow glass, swelling perlite powder, solvent by weight again, the limit warming while stirring that feeds intake, when being warmed up to 110 ℃, be incubated draining after 2 hours, then material cooled, filter and test package with 200 order filtering nets to 40 ℃ of filtrations.
This heat insulation asphalt anticorrosion paint that the present invention provides at the scene after the mixing and stirring, precipitates 10 minutes during use, sprays, brushing, roller coating all can again.
Compared with prior art, the invention has the beneficial effects as follows: coating is thin, cost is low, save labor when being coated with, and has adiabatic function, firm adhesion, and anti-wear power is strong and anti-impact force is big, chemical corrosions such as acid-and base-resisting, salt.
Embodiment
Embodiment
Earlier 30 parts of polymethylene multi-phenenyl isocyanates (PAPl) 400# is dropped in the reactor with pump, add 0.02 part of phosphoric acid and carry out emulsification, heat up while feeding intake, add 5 parts of polyethers again, 30 parts of dimethylbenzene and 5 parts of Resins, epoxy E-44, insulation is 2.5 hours when carrying out reacting by heating to 80 ℃, again with 55 parts of coal tar pitches, 12 parts of toluene, by 65 parts in the fine powder of hollow glass, 120 parts of the thermal insulation materials of 90 parts of compositions of swelling perlite powder, dimethylbenzene drops in the reactor for 30 parts successively, the limit warming while stirring that feeds intake, when being warmed up to 110 ℃, be incubated draining after 2 hours, then material cooled, filter and test package with 200 order filtering nets to 40 ℃ of filtrations.After will stirring during on-the-spot the use, spray again, brushing, roller coating all can.
