Abstract
The invention discloses a high-temperature-resistant glass flake acidproof anticorrosion primer for a desulfurizing unit, which is prepared from the following components in parts by weight: 55-60% of phenolic epoxy acrylic resin polymer, 2-4% of methylethyl ketone peroxide curing agent, 20-9% of flake mica powder, 4.8-6% of titanium white, 5-2% of barite powder, 2-4% of accelerator, 0.6-1% of leveling agent, 0.6-1% of defoaming agent and 10-13% of styrene. By using the phenolic epoxy acrylic resin polymer, the coating has the advantages of favorable high-temperature resistance, corrosion resistance, high permeability, high binding strength, solvent resistance and oxidative medium resistance. Compared with like products in China at present, the high-temperature-resistant glass flake acidproof anticorrosion primer obviously enhances the binding strength of a steel structure, has better permeability, is convenient for construction and operation, can be used for treating closed bottoms of inner walls of steel-structure desulfurizing towers of various wet-process desulfurizing units, and obviously enhances the binding strength of the integral anticorrosion coating.
Description
Technical field
The present invention relates to a kind of coating; Specifically be the pyroceram scale acid-resistant anti-corrosion priming paint that desulfurizer uses, this priming paint is applicable to the kinds of anti-sulfur corrosion sealing bottom reason of steelwork thionizer internal surface, steelwork 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 steelwork thionizer internal surface, steelwork and concrete chimney internal surface is though reach 25MPa with the cohesive strength of steelwork; 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 priming paint that a kind of desulfurizer uses, and this priming paint has also increased the cohesive strength to concrete and steelwork at anti-180 ℃ of-200 ℃ of pyritous simultaneously.
The pyroceram scale acid-resistant anti-corrosion priming paint that a kind of desulfurizer of the present invention uses, the component and the weight proportion of this priming paint are respectively: phenolic aldehyde epoxy acrylic resin polymkeric substance 55%-60%, methylethyl ketone peroxide stiffening agent 2%-4%, scale mica powder 20%-9%, white titanium pigment 4.8%-6%, ground barium sulfate 5%-2%, promotor 2%-4%, flow agent 0.6%-1%, skimmer 0.6%-1%, vinylbenzene 10%-13%.
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 hypertonicity, the high bond strength of excellent high temperature resistant, corrosion resistance nature of resol and epoxy resin concurrently.The coating of processing 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, and steelwork and concrete cohesive strength are obviously improved, and 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 steelwork thionizer internal surface, steelwork and the concrete chimney internal surface of various wet methods, dry desulfurization; Possess wide application space, obviously promote the cohesive strength of the whole corrosion protection coating of desulfurizer.
Concrete performance perameter is:
1, resistance to elevated temperatures: 180 ℃ * 2h, 200 ℃ * 2h paint film do not ftracture, do not come off.
2, the cohesive strength with steelwork reaches 25MPa.
3, reach 1MPa with the refractory brick cohesive strength behind the heat-resisting 200 ℃ * 2h; Reach 3MPa with concrete binding intensity.
