Abstract
The invention discloses a high temperature acidproof anticorrosion primer used for coating on chimney inner walls. The primer comprises, by weight, 50%-60% of organic silicon-phenolic-epoxy resin polymer, 20%-22% of fat ring amine aromatic amine epoxy curing agents, 5%-2% of flaky graphite powders, 6.6%- 2% of flake mica powders, 0.4%-0.8% of antifoaming agents, 8%-6.2% of dimethylbenzene, 3% of cyclohexanone and 2%-4% of butyl alcohol. By using the organic silicon resin, phenolic resin and ethoxyline resin polymer, coatings possess characteristics of thermostability, corrosion resistance, sulfur dioxide and sulfuric acid penetration resistance. Compared to the prior art, the primer has better penetrability and cohesiveness to concretes and refractory blocks and operation is easy. Material sources are wide and easy to get. The primer can be used for anticorrosion treatments for various kinds of steel structures and concrete chimney inner walls. Cohesive strength of overall anti-corrosion coatings can be improved.
Description
Technical field
The present invention relates to a kind of coating, specifically is the high temperature acid-resistant anti-corrosion priming paint that a kind of inner wall of stack uses, and this priming paint is applicable to concrete, refractory brick, the steel construction chimney inner surfaces enclose bottom reason of wet method, dry desulfurization, has excellent cohesive strength.
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 high temperature acid-resistant anti-corrosion priming paint that is used for concrete, refractory brick and the steel construction chimney internal surface of desulfuration field, this priming paint has strengthened the cohesive strength to concrete and steel construction at 250 ℃ of pyritous of tolerance simultaneously.
The high temperature acid-resistant anti-corrosion priming paint that a kind of inner wall of stack of the present invention uses, the component and the weight proportion of this coating are respectively: organosilicon-phenolic aldehyde-epoxide resin polymer 55%-60%, aliphatic cyclic amine-aromatic amine epoxy stiffening agent 20%-22%, flaky graphite powder 5%-2%, scale mica powder 6.6%-2%, defoamer 0.4%-0.8%, dimethylbenzene 8%-6.2 %, pimelinketone 3%, butanols 2%-4%.
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, reach 18MPa with the steel construction cohesive strength;
3, reach 3MPa with concrete binding intensity.
