Description

A kind of thermosetting alkyl polyols glycidyl ether resin composition and its application
Technical field
The invention belongs to composition epoxy resin, it is related to a kind of thermosetting alkyl polyols glycidyl ether resin Composition and its application.
Background technology
With the leap of the booming and high-frequency transmission technology for being wirelessly transferred product, to the dielectric properties of material The material of proposition requirement higher, existing epoxy resin and phenolic resin systems cannot meet advanced application, The requirement of high frequency printed circuit board cannot particularly be met.As the substrate of the printed circuit board (PCB) of low-dielectric loss Material has fluorine-type resin, but this kind of resin high cost, processing are difficult, and is led using military and space flight is confined to Domain.In addition, polyphenylene oxide resin has good mechanical property and superior dielectric performance, high frequency is increasingly becomed The first-selected resin material of printed circuit board base board, but, the polyphenylene oxide with double bond is high for manufacturing high frequency at present Fast sheet material is by radical reaction, it is necessary to special production equipment, and prepreg storage life is short, raw The regulation of production. art condition is difficult, high cost.
CN101684191B is proposed and is combined using benzoxazine, phenylethylene-maleic anhydride, phosphorus curing agent Cured epoxy resin can obtain a kind of solidfied material with compared with low-k and dielectric loss, but only The dielectric properties that material is reduced with phenylethylene-maleic anhydride inevitably occur a lot of other aspects Problem, influences especially pronounced, because non-pole in phenylethylene-maleic anhydride (SMA) molecular structure to caking property The styrol structural unit of property reduces the polarity of modified matrix resin, weakens the phase between resin and Copper Foil Interreaction force;Meanwhile, because substantial amounts of benzene ring structure increases the fragility of resin crosslinks network in SMA, Have a negative impact to the adhesive property under dynamic condition, so as to reduce between base material and base material and Copper Foil Adhesion strength.
CN100523081C proposes compound using benzoxazine, phenylethylene-maleic anhydride and other curing agent Solidifying phosphorous and non-halogen non-phosphate epoxy composite can obtain a kind of with compared with low-k and dielectric loss Solidfied material, but using phosphorous epoxy resin as matrix resin, although excellent anti-flammability, but phosphorus can be reached Excessive introducing, extreme influence necessarily is produced to the water imbibition of base material, this will certainly be many to other of sheet material Performance has negative effect.
Japanese Patent Laid-Open 2003-252958 discloses a kind of biphenyl type epoxy resin and active ester composition, There is excellent dielectric constant and dielectric loss angle tangent after said composition solidification, but due to using one kind Difunctional biphenyl epoxy resin, and active ester crosslink density is low, the glass transition temperature that there is solidfied material The relatively low shortcoming of low, heat resistance.
The A of CN 102689463 disclose a kind of Flexible copper-clad plate, and the Flexible copper-clad plate includes adhesive layer, gathers Acid imide base material and copper foil layer, according to the weight percentage of raw materials, the adhesive layer is composed of the following components: Solvent epoxy varnish 30-40 parts, 10-20 parts of solvent type epoxy toughener, 6~25 parts of halogen-free flame retardants, Antiradiation agent 1-3 parts, additive 1-3 parts, 20-40 parts of solvent I, the in the invention solvent type epoxy Toughener can be polypropylene glycol glycidol ether, but polypropylene glycol glycidol ether described in the invention is only Used as toughener, it applies content relatively low.
At present, for the performance of improvement thermosetting epoxy resin composition, major part research is concentrated on from solid Agent or toughener etc. improve resin combination physical performance, and for by the selection to matrix resin composition and Transformation is but rarely reported improving composition properties.
Therefore, it is desirable to prepare resin combination by the selection for matrix resin composition in this area, So that there is low-k and good hot property and caking property by sheet material prepared by the resin combination Energy.
