Both at home and abroad researcher mainly concentrates on Research on Toughening to cyanate to the modification of cyanate, and it is toughness reinforcing to adopt Resins, epoxy, bimaleimide resin or thermoplastic resin that cyanate ester resin is carried out, and has obtained certain achievement.Yet because the existence of ehter bond in the cyanate structure, the resistance toheat of material is caused adverse influence.Studies show that when the cyanate short burst to be exposed in the pyritous air (when carrying out spot welding), show satisfactory stability as circuit card.Yet when being in more than 200 ℃ for a long time, the weightless obviously aggravation of cyanate ester resin, this has just greatly limited its application in fields such as aerospace, and the research of this respect is also rarely had report both at home and abroad.
Phenylacetylene base silane is the novel hybrid inorganic-organic materials of a class, and this class material not only has inorganics and organic characteristic concurrently, also has the incomparable special performance of single inorganics and organism.C ≡ C key links to each other by the form of Si-C key with covalent linkage, on molecular level organic constituent and inorganic component is combined.Phenylacetylene base silane has excellent heat resisting and dielectric properties as a kind of novel silicone resin, can be used as high temperature resistant, the matrix resin of wave-penetrating composite material and the carbon matrix (ZL02151140.3 of high-performance carbon-carbon composite; ZL200510110133.5; ZL200510110132.0).
The present invention adopts the phenylacetylene base silane resin that cyanate ester resin is carried out modification, on the dielectric properties that keep the cyanate ester resin excellence, good mechanical performance basis, improve the heat-resisting and thermal oxidation of cyanate ester resin, to satisfy the requirement of high-performance transparent structure material of new generation and aerospace with high performance structures composite resin matrix.At present, yet there are no the report of relevant cyanate resin modified by phenylacetylene base silane resin both at home and abroad.
Summary of the invention
The technical problem that solves
Adopt Resins, epoxy, bimaleimide resin or high-performance thermoplastic resin modified cyanate ester resin to make the resistance toheat of material descend to some extent.For fear of the deficiencies in the prior art part, compare with the method for modifying of former cyanate ester resin, the present invention proposes a kind of cyanate resin modified by phenylacetylene base silane resin and preparation method thereof, with the heat-resisting and thermal oxidation of expectation raising cyanate ester resin, keep the dielectric properties and the good mechanical performance of cyanate ester resin excellence; Satisfy various advanced composite material moulding processs, thereby further widen the application of cyanate ester resin at high-technology fields such as Aeronautics and Astronautics.
