Abstract
The invention discloses a high-temperature acid-resistant interface agent for an inner wall of a chimney. The interface agent comprises the following raw materials by weight percent: 45%-55% of a phenolic epoxy resin polymer, 20%-22% of an aromatic amine epoxy hardening agent, 7%-5% of flake graphite powder, 0.6%-0.4% of a defoaming agent, 21.4%-13.6% of dimethylbenzene, 3%-2% of cyclohexanone and 3%-2% of butanol. Compared with the prior art, the interface agent has the characteristics that the permeability and adhesiveness to concrete and fire-resistant bricks or acid-resistant bricks are better, the construction operation is convenient, the materials are wide in source and easily available, the surfaces of various steel structures, concrete chimneys and concrete chimney lining bricks can be subjected to corrosion protection, the acid protection performance of a lining of the inner wall of the integral chimney is remarkably improved, and the integral service life of the chimney is remarkably prolonged.
Description
Technical field
The present invention relates to chemical field, specifically the acidproof interfacial agents of a kind of high temperature for inner wall of stack.
Background technology
" the chimney concrete acid-proof anticorrosive coating " using at desulfuration field concrete, refractory brick, acid resisting brick, clay brick, steel structure surface at present, although its thermotolerance reaches 250 DEG C, but its coating and concrete cohesive strength only have 1MPa, even slightly more, and the cohesive strength of steel construction only has trivial 2-3MPa.In practice of construction process, when often substrate surface still exists steam, just must construct, in actual use, produce the phenomenon coming off and happen occasionally.The reason of this Paint Falling is mainly because polymkeric substance (film forming matter) perviousness adopting is bad, cohesive strength is not enough, thermotolerance is unstable, in use coating be heated post polymerization thing (film forming matter) decompose aging due to, can not meet the technical requirements of chimney lining long-effective corrosion.
Summary of the invention
For the problems referred to above, provide a kind of high temperature for inner wall of stack acidproof interfacial agents, this interfacial agents viscosity is low, good penetrability, solidify after cohesive strength high, hard, wear-resisting, especially there is certain cohesive strength bearing benevolence after 250 DEG C of high temperature actions, come off, ftracture, bubble and be unlikely to produce, the present invention is achieved in that
For the acidproof interfacial agents of high temperature of inner wall of stack, component and the weight proportion of the acidproof interfacial agents of this high temperature are respectively: novolac epoxy polymkeric substance 45%-55%, aromatic amine epoxy stiffening agent 20%-22%, crystalline graphite powder 7%-5%, defoamer 0.6%-0.4%, dimethylbenzene 21.4%-13.6%, pimelinketone 3%-2%, butanols 3%-2%.
In the present invention, described novolac epoxy polymkeric substance is novolac epoxy polymkeric substance F44, and described defoamer is defoamer BYK066N.
Product of the present invention is film forming matter owing to having adopted novolac epoxy polymkeric substance and aromatic amine curing agent, after this resin and curative systems solidify, crosslinked fine and close, has the corrosion resistance nature of resol excellence and the hypertonicity of epoxy resin, high bond strength concurrently.Coating has high resistance toheat and heat aging property.
Product of the present invention is compared with current domestic like product; perviousness to concrete, refractory brick, acid resisting brick, clay brick, steel construction is better; cohesive strength significantly improves; its resistance to elevated temperatures and acid resistance remain unchanged simultaneously; constructability operation; material source extensively, be easy to get; can use at the concrete of various wet methods or dry desulfurization device, refractory brick, acid resisting brick, clay brick, steel construction inner wall anti-corrosive; possess wide application space, obviously promote economy and the social usefulness of desulfurizer aspect environment protection.
