Description
Technical field
The present invention relates to Resins, epoxy that contains in a kind of molecular skeleton naphthalene structure unit and alicyclic hydrocarbon structural unit and preparation method thereof.
Premium properties such as specifically, relate to have low viscosity, high glass transition temperature, easily dissolving, color and luster are more shallow, can be used as Resins, epoxy that high high temperature insulation matrix resin uses in the electric field and their preparation method.
Technical background
Resins, epoxy has good insulation performance, thermotolerance, chemical resistance, mechanical property and to the over-all propertieies such as cementability of various base materials; and after thermofixation; its shrinking percentage is significantly less than other thermosetting resin usually; thereby as composite matrix resin, packaged material, fiber reinforced material, insulation protection material etc.; by method machine-shapings such as casting, dipping, transfer mould, winding, laminations, be widely used in electric industrial circle.
As everyone knows, the equipment that uses in the electric field develops rapidly towards miniaturization, lightweight, thin typeization, densification direction.For the macromolecular material that uses in various device, performance must improve constantly, and to adapt to the demand for development of microelectronics, guarantees that electronics can steady running in various environment.
The high performance of Resins, epoxy is the problem that numerous researchists pay special attention in the recent period.As matrix resin, its high performance comprises the raising of every main heat, mechanical index, and the improvement of processing technology.Processing technology is meant the solubility property of resin in solvent, to changing conditions of inorganic substrate wettability of the surface, flowability (suitable viscosity or melt viscosity), solidification process medium viscosity etc.In short, obtain a kind of have both high heat resistance (high glass-transition temperature, Tg) and good solubility and low-viscosity epoxy resin be that the inventor wishes the target that reaches.
Yet, with regard to Resins, epoxy, the raising of thermal property usually and workabilities such as its resolvability, melt viscosity be inverse relationship.That is, if improve its Tg with the method for introducing big rigid radical on molecular skeleton, may cause its solvability variation in common solvent such as acetone and ethylene glycol monomethyl ether, melt viscosity significantly increases, and is unfavorable for complete processing.Conversely, if introduce some flexible structural unit, the viscosity (melt viscosity) of Resins, epoxy is reduced greatly as to dimethylene biphenyl, the mobile improvement, and favorable solubility in general solvent, but unfavorable to the thermotolerance that improves resin like this, its Tg is less than 150 ℃.The work of these aspects existing many researchists reported, U.S.Pat.5 for example, 780,571 (1998), U.S.Pat.5,827,908 (1998), all related to Resins, epoxy among Chinese invention patent CN1106194A and the CN1160724A with above-mentioned similar structures.Also there is the problem that costs an arm and a leg simultaneously in resin like this.
Same well knownly be, the common viscosity of cycloaliphatic epoxy resin is very low, and dielectric properties are good and stable.In the recent period a lot of research work utilize these fundamental characteristics exactly, by introducing the method for other group, further improve its thermal characteristics and other application performance.
Adducible example comprises: propose to make alicyclic olefin glycol and halo cycloolefin carry out etherification reaction among the Chinese invention patent CN1340504A and obtain alicyclic alkatrienes ether compound, use the peroxy acid oxidation then, obtain the epoxide of that include cycloaliphatic hydrocarbons structure, use anhydride type curing agent can make the Tg of cured article reach 180 ℃; Similarly, Chinese invention patent CN1340506A is by generating the coupling of halo cycloolefin alicyclic diolefine, alicyclic monoolefine pure and mild halo cycloolefin etherification reaction or with alicyclic monoolefine dehydration of alcohols synthesis of alicyclic diolefine etherate, reoxidize afterwards, can obtain a kind of viscosity and only be the liquid-state epoxy resin of 40-88mPa.s 25 ℃ of following viscosity, it solidifies back Tg is 150-166 ℃; U.S.Pat.5,312,878 (1994) disclose with containing the unitary resol of dicyclopentadiene structure and have cooperated with the Resins, epoxy that contains naphthalene as solidifying agent, and to improve liquidity, the Tg of cured article is 158-167 ℃; U.S.Pat.4,390,680 disclosed by phenol or derivatives thereof and dicyclopentadiene and other diolefine prepared in reaction phenol-hydrocarbon resin and and then prepare the method for Resins, epoxy, it is higher to obtain resin toughness, heat-drawn wire (HDT) reaches 150-160 ℃.
Can find that from above description by suitable molecular designing, synthetic Resins, epoxy with ad hoc structure truly has and may improve its performance, solves the contradictory relation of thermal property and processibility, realizes the balance of various characteristics.
Inventor of the present invention gains enlightenment from the research work that these reference have been finished just, expectation overcomes the single structure modification that prior art relates to and causes shortcoming on the Resins, epoxy performance, proposition utilizes some to be easy to get, inexpensive, contain the alicyclic olefin of two or more non-conjugated carbon-to-carbon double bonds and the compound that contains naphthyl that is easy to get equally in the molecular structure, by easier method, prepare in a kind of molecular skeleton and not only contain the inflexible naphthylene group but also the bigger alicyclic hydrocarbon structural unit of volume is arranged, the Resins, epoxy of the more shallow excellent property of color and luster, thus the present invention finished.
