Below to the detailed description of the invention.
Multi-hydroxy resin of the present invention is by shown in the above-mentioned general formula (1).Wherein, A represents naphthalene nucleus or phenyl ring, has the structure of naphthalene nucleus (N) and phenyl ring (B) coexistence, and naphthalene nucleus (N) shared ratio (mol ratio) in A is represented with N/ (N+B), is 0.2~0.7 scope.If littler than it, based on the thermotolerance of naphthalene structure, wet fastness etc. to improve effect little, if more than it, softening temperature, viscosity raise, formability reduces.Wherein, above-mentioned mol ratio is the molar average ratio of naphthalene nucleus and phenyl ring in the multi-hydroxy resin.
Above-mentioned naphthalene nucleus and phenyl ring can be replaced by the alkyl of carbon number 1~6, do not replace or by methyl substituted but be preferably.N represents average repeat number (number is average), is 1~15, is preferably 1.1~5.N is littler than it, and is not preferred aspect thermotolerance.In addition, bigger than it, then softening temperature, viscosity raise, and formability reduces.The softening temperature of multi-hydroxy resin of the present invention is 75~125 ℃ a scope, is preferably 80~120 ℃ scope.In addition, the melt viscosity under 150 ℃ is the scope of 2~10Pas, is preferably the scope of 3~8Pas.
Such multi-hydroxy resin can obtain by making the condensing agent reaction shown in phenol and aphthols and the general formula (2).
Wherein, so-called phenol, the alkyl (alkyl) that is carbon number 1~6 replaces or unsubstituted phenol, particularly, can illustration phenol, ortho-cresol, meta-cresol, p-cresol, ethylbenzene phenols, isopropyl benzene phenols, tert-butyl phenol, orthoxenol, p-phenyl phenol, 2,2,6-diethyl phenol etc., viewpoint from the low viscosity of the resin that obtains and hyperergy etc. is preferably unsubstituted phenol.In addition, so-called aphthols, alkyl replacement or unsubstituted naphthols for carbon number 1~6 are preferably unsubstituted naphthols, are in particular 1-naphthols, beta naphthal.Above-mentioned phenol or aphthols can use separately, also can will also use more than 2 kinds.
Phenol during reaction and the usage ratio of aphthols with respect to both 1 mole of total amounts, in theoretical amount, can be used 0.2~0.7 mole aphthols, if but consider reactive difference etc., can use 0.10~0.40 mole aphthols.
In addition, the naphthalene of general formula (2) is in the condensing agent, and X is the alkoxyl group of hydroxyl, halogen atom or carbon number 1~6.From with reactive viewpoint of phenoloid, preferred hydroxyl or halogen atom.As halogen atom, preferred chlorine atom, as alkoxyl group, preferred methoxyl group.2 CH with respect to naphthalene nucleus
2The position of substitution of X base can be on the identical phenyl ring, also can be on each phenyl ring, and preferred the position of substitution is 1,4-position, 1,5-position, 1,6-position, 2,6-position, 2,7-position.From the viewpoint of rerum naturas such as thermotolerance, physical strength and toughness, more preferably 1,4-position and 1,5-position.Naphthalene is that condensing agent can be these mixture, but preferred naphthalene be in the condensing agent, 1,4-two replaces bodies and 1, the total containing ratio that 5-two replaces bodies is more than the 90 weight %.
Naphthalene shown in the general formula (2) is a condensing agent, is not particularly limited, usually can be via the chlorination reaction of the methyl of the chloromethylation of naphthalene or dimethylnaphthalene class and make.In the condensing agent, can contain and have only 1 CH on the naphthalene nucleus
2Single naphthalene class that replaces that the X base replaces, but single content that replaces body is below the 10wt%, is preferably below the 5wt%, more preferably below the 3wt%.If the content of single replacement body is more than it, the cross-linking density when making resin solidification sometimes reduces, and brings stable on heating reduction.
Phenoloid and naphthalene are in the reaction of condensing agent, are condensing agent with respect to naphthalene, use excessive phenol and aphthols.Naphthalene is the usage quantity of condensing agent, with respect to 1 mole of the total amount of phenol and aphthols, is 0.05~0.35 mole scope, is preferably 0.1~0.3 mole scope.If more than it, the softening temperature of resin raises, and brings obstacle for operations for forming.In addition, if lack than it, after reaction finished, the phenol of excessive use and the removal amount of aphthols increased, industrial not preferred.Naphthalene is a condensing agent, owing to compare use slightly with theoretical amount, can be the moment that condensing agent reacts to finish to react at the naphthalenes of all measuring basically.
This reaction can be carried out in the presence of acid catalyst, as this acid catalyst, can suitably select from known mineral acid, organic acid.As such acid catalyst, can enumerate for example mineral acids such as hydrochloric acid, sulfuric acid, phosphoric acid, organic acids such as formic acid, oxalic acid, trifluoroacetic acid, tosic acid, diethyl sulfuric acid, solid acid such as Lewis acid such as zinc chloride, aluminum chloride, iron(ic) chloride, boron trifluoride or atlapulgite, silica-alumina, zeolite etc.In addition,, use under the situation of dichloride methyl naphthalene, can under catalyst-free, react as the condensing agent shown in the general formula (2).
Usually, this is reflected at and carried out under 10~250 ℃ 1~20 hour.In addition, as reaction solvent, can use alcohols such as methyl alcohol, ethanol, propyl alcohol, butanols, ethylene glycol, methylcyclohexane, ethyl cellosolve, benzene, toluene, chlorobenzene, dichlorobenzene etc.
After reaction finishes, adopt methods such as neutralization, washing sometimes, catalyzer is removed, adopt method such as underpressure distillation that remaining solvent and unreacted phenoloid are removed to outside the system as required, obtain the multi-hydroxy resin.The unreacted phenoloid is generally below 3%, is preferably below 1%.If more than it, the thermotolerance when forming cured article reduces.But, use under the situation of the phenoloid more than 2 yuan in the reaction, can remaining phenoloid not removed after the reaction.
Among the present invention, can contain the multi-hydroxy resin of naphthyl methyl bonding in the multi-hydroxy resin shown in the above-mentioned general formula (1).For example, at the naphthalene with the phenoloid reaction is in the condensing agent, contain under the situation of monochloro methylnaphthalene, monohydroxy naphthalene or monoalkoxy methylnaphthalene the mixture of the multi-hydroxy resin that becomes general formula (1) and the compound of the naphthyl methyl addition more than 1 or 1 on the aromatic ring of the multi-hydroxy resin of general formula (1).Even their mixtures can not produce obstacle to bringing into play effect of the present invention yet, they can be used as epoxy curing agent, and can use as the raw material of Resins, epoxy of the present invention.
Resins, epoxy of the present invention is represented by above-mentioned general formula (3).Wherein, A is identical with the explanation of the multi-hydroxy resin of general formula (1) with n.The softening temperature of Resins, epoxy of the present invention is 60~100 ℃ a scope, more preferably 75~95 ℃ scope.In addition, the melt viscosity under 150 ℃ is the scope of 0.1~1.0Pas, more preferably the scope of 0.2~0.8Pas.
