Embodiment 1

[0029] A kind of preparation method of the cyanate ester modified resin of low Dk / Df value, comprises the following steps:

[0030] 1) 42% novolac epoxy resin by weight ratio; 42% P-containing phenolic resin; 10% cyanate resin is made into a solution, and mixed to obtain a mixed solution;

[0031] 2) Add 6% by weight diluent acetone to the mixed liquid in step 1) to adjust to a suitable solid content of 70%. (Add propylene glycol methyl ether to make glue; glass fiber cloth is dipped in glue and dried; pressed with copper foil to make copper clad laminate) At this time, the Dk / Df value of the solidified product of the cyanate modified resin is 4.1 / 0.011.

[0032] In addition, it is also possible to add 15% PTFE resin micropowder in the weight percentage to the cyanate ester modified resin solid obtained in step 2), stir evenly, (adding propylene glycol methyl ether is adjusted into a glue solution; glass fiber cloth is dipped in glue, baked Dry; pressed with copper foil to ...

Embodiment 2

[0034] A kind of preparation method of the cyanate ester modified resin of low Dk / Df value, comprises the following steps:

[0035] 1) 42% novolac epoxy resin by weight ratio; 42% P-containing phenolic resin; 10% cyanate resin is formulated into a solution, and mixed to obtain a mixed solution;

Abstract

The invention discloses cyanate ester modified resin with low Dk / Df value as well as a preparation method thereof. The cyanate ester modified resin with low Dk / Df value as comprises the following rawmaterial components in percentage by weight: 30 to 50 percent of novolac epoxy resin, 30 to 50 percent of P-containing phenolic resin and 8 to 12 percent of cyanate ester resin. The cyanate ester modified resin with low Dk / Df value is prepared by the following steps: preparing a solution type mixture from the raw material components, adjusting the mixture to proper solid content by 4 to 8 percentof diluent acetone, adding 15 to 20 percent of PTFE resin micropowder and stirring uniformly to prepare the cyanate ester modified resin with low Dk / Df value.

Description

technical field [0001] The invention relates to a cyanate-modified resin, which belongs to the technical field of polymer materials, in particular to a cyanate-modified resin with a low Dk / Df value and a preparation method thereof. Background technique [0002] The development of human society is closely related to the progress of material science. As one of the four high-performance resin matrix materials, cyanate resin has excellent dielectric properties, mechanical properties, heat resistance, bonding properties, and low moisture absorption. Can be widely used in various fields. Cyanate ester modified epoxy resin can improve the dielectric properties of epoxy resin, but the Dk / Df is still high. [0003] Therefore, how to provide a cyanate ester-modified resin with a low Dk / Df value is a technical problem that those skilled in the art continue to solve. Contents of the invention [0004] In order to solve the problems in the prior art, the purpose of the present invent...
