Description

A kind of bicomponent catalyst that can be used for the cyanate curing reaction and preparation method thereof
Technical field
The invention belongs to chemical field, relate to catalyzer, be particularly useful for the catalyzer of the curing reaction of cyanate ester resin.
Background technology
Cyanate ester resin is a kind of thermosetting resin, has good heat-resistant, mechanical property, dielectric properties and moisture-proof thermal stability etc.As the matrix resin of preparation performance resins based composites, cyanate and matrix material thereof can be used as structured material, electromagnetic wave transparent material, adhesives, dielectric function material etc. and are applied to fields such as aerospace field, electronic information.
Yet simple cyanate is difficult to the thermofixation moulding, is not both having under the situation of extra catalyst, and its thermofixation reaction is slow and difficult.Therefore, be easy to the thermofixation moulding, must in resin system, add catalyzer to promote its curing reaction in order to make cyanate ester resin.
At present known compound that can catalysis cyanate thermofixation reaction mainly contains following a few class: compound catalyst (as phenol, amine, imidazoles etc.), transition metal salt/nonyl phenol mixed catalyst, UV-light activated catalyst and the organo-tin compound catalyzer etc. that contain reactive hydrogen.Find that in actual applications catalyzer has bigger influence to cyanate cured resin and performance of composites thereof.
Though contain the thermofixation reaction that the compound of reactive hydrogen can the catalysis cyanate, its large usage quantity can also generate the imines class by product of poor heat resistance with the cyanate ester monomer reaction, has reduced the heat-resistant stability of cured resin, does not generally use separately.
At US 4,608, in 434, the hybrid catalyst system of having reported transition metal salt (octylate of zinc, tin, copper, cobalt etc., naphthenate, acetylacetonate etc.) and nonyl phenol has advantages of high catalytic activity to the curing reaction of cyanate.The hydrotropy effect of transition metal salt is played in the adding of nonyl phenol on the one hand, and it still is a promotor on the other hand.But the catalytic selectivity of this class catalyzer is poor, transition metal salt is in the curing reaction while of catalysis cyanate, pyrolysis and hydrolysis reaction that can catalysis paracyanogen acid esters under higher temperature can cause adverse influence to cyanate cured resin and performance of composites thereof.
At US 5,215, in 860, reported that a class has the active organic transition metal composition catalyst of UV-light.It mainly is cyclopentadiene metallic carbonyls title complex, it at first mixes the reaction that cyanate functional group substituted carbonyl takes place in the back under ultraviolet light irradiation with cyanate ester monomer, and generate the catalyst activity component, use the curing reaction of this catalyst activity catalytic cyanate again.This class catalyzer has catalytic activity and selectivity preferably, but the influence of its catalytic activity and preparation process is bigger, promptly is subjected to the intensity of ultraviolet light irradiation, the difference of time, and catalytic activity changes greatly, and level of response is difficult to control.Simultaneously, cyclopentadiene metallic carbonyls title complex costs an arm and a leg, and also is unfavorable for applying of it.
A kind of organo-tin compound catalyzer (H 9C 4) 2Sn (NCO-R-OCN) 2, it can by price suitably, the commercialization reagent that is easy to obtain is through the prepared in reaction of simple controllable, has advantages of high catalytic activity and selectivity, simultaneously, it and cyanate ester monomer have good compatibility, do not need to add solubility promoter or stablizer etc.Its feature structure can be expressed as:
Figure C200510112250D00041
(H 9C 4) 2Sn (NCO-R-OCN) 2(NCO-R-OCN is a cyanate ester monomer, and the R group depends on the structure of the cyanate ester monomer that is adopted)
This component can be by document (Wenfeng Li, Guozheng Liang, Wenli Xin, Trizane Reactionof Cyanate Ester Resin Systems Catalyzed by Organic Tin Compound:Kinetics andMechanism, Polymer International, 2004, the method preparation of 53:869-876) being introduced.The raw material that is adopted is dibutyl tin laurate (DBTDL) and cyanate ester monomer (as bisphenol A cyanate ester, bis-phenol L type cyanate etc.), the primary process of its preparation is: take by weighing DBTDL and cyanate ester monomer by 1:2 (mol), at 60～80 ℃ of reaction 20～30min, promptly make the organo-tin compound catalyzer.
Yet,, be about every 1g cyanate ester monomer and need add organotin catalysts [Sn] 50～500*10 because the consumption of this organotin catalysts is very little -6G, wayward its add-on makes to be restricted in actual use.
