Abstract
An anticorrosion refractory resin used for the equipment and pipeline working at 120-180 deg.C is prepared from epoxy resin, unsaturated monocarboxylic acid, phenol, and cross-linking monomer through synthesizing at 85-115 deg.C under existance of catalyst which is the mixture of organic peroxide, alkali and organic amine.
Description
Technical field
The present invention relates to a kind of high temperature corrosion-resisting resin, particularly a kind of vinyl ester resin is used for anticorrosion under high-temperature corrosion environment of metal and non-metallic material, can substitute other class corrosion-resistant metal materials such as lass lining, graphite, fluoroplastics material.
Background technology
Vinyl ester resin all has manufacturer production both at home and abroad at present, but its use temperature is all not high, the Atlac590 of domestic W2-2, the Derakne470 of the U.S., Holland, and the life-time service temperature can reach 120 ℃.The Ripoxy of the Derakne-411 of domestic MFE-2, MFE-3, the U.S., Japan, the life-time service temperature has only 100 ℃.And vinyl ester resin organic solvent-resistant in the market and high dense acetic acid poor performance are lower than Resins, epoxy with the adhesive property of other materials.
The vinyl ester resin that U.S. Pat 4480077 is introduced, be by dihydroxyphenyl propane, bisphenol A epoxide resin, methacrylic acid, cis-butenedioic anhydride, under the katalysis of superoxide (as methylethyl ketone peroxide or tertbutyl peroxide etc.), carry out the synthetic product, heat-drawn wire has only 108 ℃.The vinyl ester resin that U.S. Pat 5614299 is introduced is by cis-butenedioic anhydride, phthalic anhydride, 2-methyl isophthalic acid, and 3 propylene glycol, 1,4 cyclohexanedimethanoester ester synthesize, though this product can be high temperature resistant more than 200 ℃, it is mainly used in the making substrate for printed circuit board.
Anticorrosion market is the main application fields of vinyl ester resin, and it has excellent acidproof, alkali corrosion resistance ability.When use temperature was lower than 100 ℃, used in the market vinyl ester resin can both satisfy, but was 120 ℃-180 ℃ scope in the life-time service temperature, and under the acid concentration condition with higher, example hydrochloric acid 32% when sulfuric acid 60% is above, just can't satisfy.
Summary of the invention
The object of the present invention is to provide a kind of high temperature corrosion-resisting resin, particularly a kind of high temperature corrosion-resisting resin that can be used for equipment, pipeline between 120 ℃～180 ℃ temperature.
High temperature corrosion-resisting resin of the present invention, its composition of raw materials consists of:
A.30％～50％
B.14.2％～18.5％
C.25％～40％
D.0.01％～0.05％
E.10％～15％
Wherein:
A. epoxy resin: can be selected from bisphenol A epoxide resin, novolac epoxy, polybutadiene epoxy resin, ester ring family epoxy etc., wherein bisphenol A epoxide resin, novolac epoxy are better.
B. unsaturated monocarboxylic acid: can be selected from methacrylic acid, vinylformic acid, butenoic acid etc.
C. crosslinkable monomers: can be selected from vinylbenzene, acrylate, methacrylic ester, chloro-styrene etc.
D. phenols: can be selected from Resorcinol, benzoquinones, p-ten.-butylcatechol, methyl hydroquinone etc.
E. catalyzer: be organo-peroxide, the mixture of alkali and organic amine.
This resin is by A, B, D, E are dropped into polymeric kettle, and under 100～125 ℃, polymerization isomery 1.5～2.5 hours adds C then, obtains at 80～100 ℃ times crosslinked 1.0～2.5 hours.
Organo-peroxide can be tertbutyl peroxide, benzoyl peroxide, methylethyl ketone peroxide etc. in the catalyzer of the present invention, and the organo-peroxide that the system vinyl ester resin catalyzer of being introduced among the similar US4480077 is commonly used all can; Alkali in the catalyzer is not limited, and alkaline matter gets final product, as NaOH, Na
2CO
3Or the like, the organic amine in the catalyzer can be trolamine, mphenylenediamine, benzyldimethylamine or the like; Catalyzer is formed proportioning and is formed and different according to the different material that adopts, and it is 85～90: 5～10 that the catalyzer that the present invention recommends is formed mass mixing ratio: 5～10; Preparation of catalysts can adopt simple blending, the powerful mode that stirs to prepare.
The catalyzer that the present invention is used not only can play katalysis, and have isomerization, and can decompose fully in resin is synthetic.The product that decomposes can participate in grafting, isomery and the addition reaction of resin fully, and can provide the resin formation high-temperature-resistant structure required partial monosomy, has therefore simplified preparation technology.Owing to once feed intake, series reaction such as open loop, grafting, isomery, decomposition, catalysis, addition, copolymerization are carried out in same device continuously, (for having now about half of production technique) with short production cycle, energy consumption and production cost are low, the earning rate height of resin the most important thing is to capture the difficult problem of recurrent in the production of resins " resin autohemagglutination ".
Cross-linking monomer of the present invention and consumption not only play a part to regulate the resin workability, and influence the corrosion resistance nature of resin, therefore can select the kind and the consumption of cross-linking monomer according to different needs.
High temperature corrosion-resisting resin of the present invention can be used instrument constructions such as spray gun, hairbrush, and saturable fiberglass products is made glass reinforced plastic lining and glass reinforced plastic equipment.
High temperature corrosion-resisting resin of the present invention can be widely used in petrochemical complex; chemical industry; metallurgical; electric power; light industry; pharmacy; electronics; aerospace; heating power; plumbing; municipal administration; the equipment of industries such as environment protection (comprising: reactor; tower; basin; storage tank; electrolyzer; shell and tube heat exchanger; plate-type heat exchanger; U type tubular heat exchanger; spiral-plate exchanger; fin-tube heat exchanger; tube exchanger); pipeline and pipeline accessory (comprising: pipeline; pipe fitting; pump; valve) protection against corrosion and high temperature corrosion-resisting sealing material and sealing article, and can be used to make glass fiber reinforced plastics product.It is anticorrosion that but life-time service carries out in equipment, the pipeline between 120 ℃～180 ℃ temperature, and result of use is good.
