Abstract
The invention discloses acid-resistant corrosion-resistant finish paint for a high-temperature-resistant glass flake used by a desulfurizer. The finish paint comprises the following components in percentage by weight: 50 to 60 percent of phenolic aldehyde epoxy acrylate resin polymer, 2 to 4 percent of methyl ethyl ketone peroxide hardening agent, 15 to 5 percent of barite powder, 20 to 10 percent of flaky mica powder, 2 to 4 percent of accelerating agent, 0.4 to 1 percent of leveling agent, 0.6 to 1 percent of defoaming agent and 10 to 15 percent of styrene. The phenolic aldehyde epoxy acrylate resin polymer is adopted, so the coating has excellent high temperature resistance, corrosion resistance, high hardness, solvent resistance and oxidant resistance. Compared with the like products in China at present, the finish paint obviously improves properties of resisting sulfur dioxide, sulfuric acid and the like, has higher corrosion medium impermeability, is convenient to construct and operate, has wide and readily available material sources, can be applied to performing corrosion-resistant coating covering treatment on the inner walls of steel structure desulfurizing towers of various wet desulfuration devices, and obviously improves wear resistance and impermeability of the whole corrosion-resistant coating.
Description
Technical field
The present invention relates to a kind of coating, specifically is the pyroceram scale acid-resistant anti-corrosion finish paint that desulfurizer uses, and this finish paint is applicable to the kinds of anti-sulfur corrosion coat finishing of steel construction thionizer internal surface, steel construction and the concrete chimney internal surface of wet method, dry desulfurization.
Background technology
At present, " the glass flake lining coating (clay) " that uses at desulfuration field steel construction thionizer internal surface, steel construction and concrete chimney internal surface is though reach 25MPa with the cohesive strength of steel construction, but its coating heat resistance has only 140 ℃, in actual use, cause the phenomenon of coating shedding to happen occasionally because of TRANSIENT HIGH TEMPERATURE greater than 180 ℃.
Summary of the invention
Technical problem to be solved by this invention provides the novel fire resistant glass flake acid-resistant anti-corrosion finish paint that a kind of desulfurizer uses, 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 anti-180 ℃ of-200 ℃ of pyritous simultaneously.
The pyroceram scale acid-resistant anti-corrosion finish paint that a kind of desulfurizer of the present invention uses, the component and the weight proportion of this finish paint are respectively: phenolic aldehyde epoxy acrylic resin polymkeric substance 50%-60%, methylethyl ketone peroxide stiffening agent 2%-4%, ground barium sulfate 15%-5%, scale mica powder 20%-10%, promotor 2%-4%, flow agent 0.4%-1%, defoamer 0.6%-1%, vinylbenzene 10%-15%.
The present invention is owing to adopted phenolic aldehyde epoxy acrylic resin polymkeric substance, and this resin belongs to the resin of high crosslink density, has high temperature resistant, the corrosion resistance nature of resol excellence and hypertonicity, the high bond strength of Resins, epoxy concurrently.The coating of making has high resistance toheat (155 ℃ heat-drawn wires) and heat aging property, and superior corrosion resistance, anti-solvent, scale resistance dielectric behavior.
Product of the present invention is compared with present domestic like product; steel construction and concrete cohesive strength are obviously improved; perviousness is better; its resistance to elevated temperatures reaches 180 ℃ simultaneously; be convenient to constructing operation, material source extensively, be easy to get, can use at the kinds of anti-sulfur corrosion of steel construction thionizer internal surface, steel construction and the concrete chimney internal surface of various wet methods, dry desulfurization; 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: 180 ℃ * 2h, 200 ℃ * 2h paint film do not ftracture, do not come off.
2, wear resistance: abrasion 0.054g (1000g/1000r).
3, the cohesive strength with steel construction reaches 25MPa.
4, reach 1MPa with the refractory brick cohesive strength behind the heat-resisting 200 ℃ * 2h; Reach 3MPa with concrete binding intensity.
5, anti-90 ℃ * 40% sulfuric acid liquid, paint film did not have any variation in 7 days.
