Abstract
The disclosed modified cyanate resin is fused and copolymerized by the dicyclopentadiene cyanate resin of 2-140 weight shares and 1-40 polyurethane elastomer, has high ductility and strength and super dielectric property, and thermostable and heat-wet proof for wide application. The fractional fusion and copolymerization method has no pollution and wide application.
Description
Technical field
The present invention relates to a kind of polyurethane elastomer and dicyclopentadiene cyanate ester resin modifier and preparation method.
Background technology
Cyanate ester resin has excellent dielectric properties, high heat resistance, good comprehensive mechanical properties and extremely low water-intake rate, is a kind of functional materials and the structured material that has had potentiality since the twentieth century in aviation field.Cyanate ester resin has multiple structure, and wherein dicyclopentadiene type ethylene rhodanate resin makes it have than more excellent mechanics, calorifics and the dielectric properties of bisphenol A cyanate ester resin commonly used because of its distinctive molecular structure.But the same with the cyanate ester resin of other types, the cured article of dicyclopentadiene type ethylene rhodanate resin is more crisp, just has important practical value after having only toughening modifying.At present the toughening modifying about cyanate concentrates on bisphenol A cyanate ester resin, and the method that is adopted mainly contains: with polymkeric substance copolymerization/blend, compound etc. with inorganic nano-particle.Toughening modifying about dicyclopentadiene type ethylene rhodanate resin is studied seldom, if adopt existing toughened system to dicyclopentadiene type ethylene rhodanate resin, may can reduce its original thermal characteristics, dielectric properties or processing characteristics in toughness reinforcing.Therefore, research and develop a kind of have high tenacity, strong intensity, the thermotolerance of excellence and the dicyclopentadiene type ethylene rhodanate modification body of good dielectric properties, and a kind of direct, simple, pollution-free, suitability is wide, the simple preparation method of operating procedure, has important science and application value.
Summary of the invention
Have high tenacity in order to overcome the problem that background technology exists, to the object of the present invention is to provide, strong intensity, excellent thermotolerance and ammonia ester elastomer and the dicyclopentadiene cyanate ester resin modifier and the preparation method of good dielectric properties.
For achieving the above object, the technical solution used in the present invention is:
One, polyurethane elastomer and dicyclopentadiene cyanate ester resin modifier by weight, are that 2～140 parts of dicyclopentadiene type ethylene rhodanate resins and 1～40 part of polyurethane elastomer are through the step melting copolymerization.
Two, the preparation method of polyurethane elastomer and dicyclopentadiene cyanate ester resin modifier, by weight, earlier with 1～40 part of dicyclopentadiene cyanate ester resin and 1～40 part of polyurethane elastomer at 50～180 ℃ of fusion copolymer-1-3h; And then add 1～100 part of dicyclopentadiene type ethylene rhodanate resin, and mix, promptly obtain polyurethane elastomer and dicyclopentadiene cyanate ester resin modifier.
Described polyurethane elastomer is liquid pfpe type or PAUR elastomerics, and molecular weight is 3000～5000.
The present invention compares the beneficial effect that has with background technology: prepared Resins, epoxy and thermosetting cyanate ester resin copolymer have high-ductility, high-strength, high temperature resistant, excellent dielectric properties and wet-hot aging performance.In addition, that the step melting copolymerization method that is adopted has is direct, simple, pollution-free, suitability is wide, the simple method of operating procedure.Can be used as the modification body of tackiness agent, composite resin matrix, coating or other polymkeric substance.
