Description

Resin composition, prepreg, insulating film, metal-clad laminate, and printed wiring board provided with same
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a resin composition with high heat resistance, high modulus, low dielectric constant, low dielectric loss and low warpage, a prepreg, an insulating film, a metal foil-clad laminated board and a printed circuit board with the resin composition.
Background
With the upgrading of technologies, new requirements are put on PCBs in the consumer electronics markets such as automobile markets and smart phones, and after the 5G commercial market appears in 2018, the requirements on the dielectric property of PCB base materials are further stepped, and the high-frequency high-speed copper-clad plate is one of indispensable electronic base materials in the 5G era. In short, the PCB substrate material needs to have a low dielectric constant and dielectric loss tangent to reduce the delay, distortion and loss of signals during high-speed transmission and the interference between signals. Accordingly, it is desirable to provide a thermosetting resin composition which can exhibit a sufficiently low dielectric constant and a sufficiently low dielectric loss tangent in a signal transmission process of high speed and high frequency, in a printed circuit board material produced using the thermosetting resin composition.
In the prior art, materials prepared from thermosetting resin compositions taking epoxy resin and curing agent thereof as essential components have the advantages of good heat resistance, insulativity, processability, low cost and the like, so the thermosetting resin compositions are widely applied to electronic materials such as semiconductors, printed circuit boards and the like. The curing agent commonly used for epoxy resins includes polyamine, acid anhydride, phenolic resin, etc. Curing agents containing active hydrogen in their molecular structure, such as amines and phenolic resins, have a large number of hydroxyl groups in the cured epoxy resin, which results in an increase in the water absorption of the cured product and a decrease in the wet heat resistance and dielectric properties. To solve the above problems occurring when the conventional curing agents cure epoxy resins, active esters have been found to be a promising curing agent for epoxy resins. The active ester can react with the epoxy resin under a mild condition; meanwhile, the epoxy resin cured by the active ester does not contain hydroxyl and replaces ester group, and an epoxy resin cured product with excellent moisture and heat resistance and dielectric property can be obtained. Japanese patent laid-open Nos. JP2002012650A, JP2003082063A, JP2004155990A, JP2009235165A and JP2012246367A disclose active ester resins which are used as curing agents for epoxy resins to suitably reduce the dielectric constant and dielectric loss of cured epoxy resins, and generally the dielectric constant is 2.8 to 3.3 and the dielectric loss is 0.002 to 0.005. However, in the case of producing a high-performance substrate for high frequency and high speed, in order to improve heat resistance, thermal expansion coefficient or flame retardancy, other components such as bismaleimide resin, benzoxazine resin or phosphorus-containing flame retardant are added to the resin composition, and thus the dielectric constant of the finally obtained substrate material still fails to satisfy the requirements of the high-frequency and high-speed substrate.
On the other hand, among the existing resin materials for manufacturing printed circuit boards, bismaleimide is one of the excellent resins, and is a thermosetting resin containing an imide structure, and the high crosslinking density after curing makes the resin have high glass transition temperature, excellent thermal stability and higher rigidity, and is one of the first materials for manufacturing thin substrates at present. However, the cured bismaleimide resin has a great brittleness, and the improvement of the warpage of the sheet material is insufficient, so that the application of the bismaleimide resin to high-performance sheet materials such as thin package substrates is limited.
In view of the above, it is desirable to provide a novel resin composition, and a prepreg, an insulating film, a metal-clad laminate, and a printed wiring board having the same to solve the above problems.
