Abstract
The invention discloses a high-temperature acid-resistant corrosion-resistant finish paint used for an inner wall of a chimney. The finish paint comprises the following components in mass ratios: 30 to 40 percent of organic silicon-phenolic aldehyde-epoxy resin polymers, 8 to 14 percent of alicyclic amine-aromatic amine epoxy hardeners, 22 to 25 percent of flaky graphite powder, 23.5 to 6.2 percent of barium sulfate, 0.5 to 0.8 percent of defoamers, 11 to 12 percent of dimethylbenzene, 3 to 1 percent of cyclohexanone, and 2 to 1 percent of butanol. Because the organic silicon resin, the phenolic resin, and the epoxy rein polymers are adopted in a product, a coating has excellent high-temperature resistance, corrosion resistance, sulfur dioxide and sulfuric acid penetration resistance. Compared with the prior art, the finish paint disclosed by the invention can be used for obviously improving corrosion resistance of concrete and a refractory brick, is convenient for construction operation, has broad and readily-available material sources, and can be applied to top facing of corrosion-resistant coating on the inner walls of various steel and concrete chimneys, so that the wear-resistant and penetration-resistant properties of the entire corrosion-resistant coating can be obviously improved.
Description
Technical field
The present invention relates to a kind of coating, specifically is the high temperature acid-resistant anti-corrosion finish paint that a kind of inner wall of stack uses, and this finish paint is applicable to concrete, refractory brick, the steel construction chimney internal surface of wet method, dry desulfurization, has the kinds of anti-sulfur corrosion function.
Background technology
Present " the chimney concrete acid-resistant anti-corrosion erosion coating " that uses at desulfuration field concrete, refractory brick and steel construction chimney internal surface, though its thermotolerance reaches 250 ℃ * 1h, but its coating and concrete cohesive strength have only the cohesive strength of 1MPa and steel construction to have only 2MPa.In the practice of construction process, just must construct when often still there is steam in concrete surface,, in actual use, produce the phenomenon that comes off and happen occasionally because the perviousness of existing " chimney concrete acid-resistant anti-corrosion erosion coating " is not fine.The reason that this coating comes off mainly is because polymkeric substance (film forming matter) thermotolerance that adopts is not high, in use coating be heated post polymerization thing (film forming matter) decompose aging due to.And existing " chimney concrete acid-resistant anti-corrosion erosion coating " surface hardness is relatively poor, and wear resistance is bad, and through 1000 tests of the reciprocal wiping of ballast 450g, the wearing and tearing of flue dust can not be effectively born in discovery.
Summary of the invention
Technical problem to be solved by this invention provides a kind of novel acid-resistant anticorrosion paint finish paint that is used for concrete, refractory brick and the steel construction chimney internal surface of desulfuration field, this finish paint has also strengthened the wear resisting property of Bulk coat and anti-permeability performance, the anti-laying dust performance of staiing at 250 ℃ of pyritous of tolerance simultaneously.
The high temperature acid-resistant anti-corrosion finish paint that a kind of inner wall of stack of the present invention uses, the component and the weight proportion of this finish paint are respectively: organosilicon-phenolic aldehyde-epoxide resin polymer 30%-40%, aliphatic cyclic amine-aromatic amine epoxy stiffening agent 8%-14%, flaky graphite powder 22%-25%, barium sulfate 23.5%-6.2%, defoamer 0.5%-0.8%, dimethylbenzene 11%-12%, pimelinketone 3%-1%, butanols 2%-1%.
Product of the present invention is owing to adopted silicone resin, resol, epoxide resin polymer, this resin belongs to the resin of high crosslink density, has high temperature resistant, the corrosion resistance nature that resol is excellent of silicone resin excellence and hypertonicity, the high bond strength of Resins, epoxy concurrently.The coating of making has high resistance toheat and heat aging property, superior corrosion resistance, anti-solvent and scale resistance.
Product of the present invention is compared with present domestic like product; cohesive strength to concrete, refractory brick and steel construction obviously improves; perviousness to concrete and refractory brick is better; its resistance to elevated temperatures and acid resistance remain unchanged simultaneously; be convenient to constructing operation; material source extensively, be easy to get; can be in the anticorrosion use of inner wall of stack of materials such as the concrete of various wet methods or dry desulfurization device, refractory brick, steel construction; possess wide application space, obviously promote economy and the social usefulness of desulfurizer aspect environment protection.
The specific performance parameter is:
1, resistance to elevated temperatures: 250 ℃ * 3h paint film does not ftracture, does not come off;
2, wear resistance: abrasion 0.091g (500g/1000r);
3, anti-40% sulfuric acid liquid, paint film did not have any variation in 30 days.
