Description
Technical field
The present invention relates to a kind of preparation technical fields of polyimides compound resin, and in particular to it is a kind of by polyimides with
The polyimides compound resin that copolymerization obtains is blended in poly methylene imine, the characteristic with low-k, in high-frequency high-speed route, electricity
Sub- Material Field has good application.Polyimides compound resin and corresponding flexibility coat copper plate of the invention is suitable for high frequency
Transmission flexible print wiring board, the insulating substrate of high-frequency electron device, high fidelity signals transmission, all kinds of electric equipment products
In.
Background technique
Polyimide resin is a kind of high performance engineering plastics, because of its intrinsic heat resistance, heatproof oxidation performance energy, is changed
Learn stability and excellent mechanical property, cold-resistant thermal shock, long-term use temperature range is from -50 DEG C to 250 DEG C, in industrial products
In be widely used.Polyimides has excellent insulation performance, and mechanical performance is high, and processability is strong, in electronic product, especially
In consumer high-end electronic product, such as mobile phone, tablet computer, camera product, have a wide range of applications.
Current electronic product constantly high-endization, mobile phone will also release the type of 5G signal transmission, the base station of 5G signal
To start to build, this proposes requirements at the higher level to the wiring board inside electronic product: on the one hand, insulating materials needs to have on wiring board
There are lower dielectric constant and dielectric loss, guarantee that 5G signal is undistorted in transmission process, guarantees wiring board under 5G mode
Work is not generated heat；On the other hand, the copper conductor on 5G semaphore request internal circuit board has better efficiency of transmission, due to electric current
Skin effect cause electric current conduction to be carried out on copper conductor and insulating basement membrane layer contact surface, therefore copper conductor and insulating substrate
Between roughness it is as low as possible, reduce signal transmission rate reduce and energy loss.Current board substrate, with epoxy
Based on resin, acrylic resin and polyimide resin, the dielectric constant of polyimide resin is 3.3-3.4, and dielectric loss is about
It is 0.007, is the material of the requirement of the closest 5G signal transmission of performance in these materials.Even so, polyimide resin
Dielectric constant or higher, transmission loss, distortion and route when 5G signal being caused to transmit are generated heat.
In general, the method for reducing the dielectric constant of polyimide resin, Ke Yiyou: pore-creating in film, fluororesin are mixed
Miscellaneous modification, modified, the fluorochemical monomer modification of aliphatic monomer etc..Pore-creating will cause the reduction of film mechanical performance in film, can also make
It is reduced at insulation performance, increasing electrical breakdown may；The hole made requires aperture submicron order or 100nm hereinafter, being difficult to control
Obtain the film of such small-bore, even aperture distribution.The doping vario-property of fluororesin, the dielectric that film is reduced by being blended are normal
Number；But the compatibility of fluororesin and polyimide resin is very poor, is easy to appear and mutually separates, mechanical performance is caused to significantly reduce.
Aliphatic monomer is modified, cuts off the charge transfer effect of polyimide molecule chain, can reduce dielectric constant；But aliphatic chain
It introduces, unavoidably heat resistance is caused to reduce；Although heat labile molecule segment can be dispelled by preparatory high-temperature process to mention
High subsequent heat resistance, but the mechanical performance that will cause final Kapton in this way reduces, it is also possible to it causes empty in film
Hole reduces the breakdown voltage of film.The dielectric constant of polyimides can be significantly reduced in the modification of fluorochemical monomer, passes through fluorine
The strong electron-withdrawing ability of atom reduces the dipole moment of molecule segment, passes through the repulsive interaction of fluoro-containing group and other molecule segments
Increase the gap of molecule interchain, above two ability makes fluorinated polyimide have lower dielectric constant.Even if but
In this way, the dielectric constant of polyimide resin be not yet it is very low, there is the space that further decreases；More it is essential that containing
Fluorine monomer generally is flexible unit, and the reduction of molecule chain rigidity is caused after introducing, and heat resistance can be reduced with dimensional stability, simultaneously
It causes molecule segment degree of orientation in the face of film to reduce, causes the increase of thermal expansion coefficient, application difficult in assist side.
Poly methylene imine is the height-oriented high molecular material of molecule chain, while having very strong rigid structure.It is tied
The major defect of structure is because molecule chain rigidity is too strong, caused by the longitudinal mechanical performance with transverse direction of film mismatch completely.One
As for, the poly methylene imine film being prepared using coating/melting extrusion method, strand is height-oriented in longitudinal direction,
It is longitudinal that there is excellent mechanical performance, and laterally there is film embrittlement, form threadiness division.But poly methylene imine molecular
On chain, it is made of imine group, rather than imide ring；There is no carbonyls, therefore have lower dipole moment, dielectric constant phase
To reduction.If the polyimides of itself and flexible structure is copolymerized, the mechanical performance after forming a film can be improved, can also reduce
The dielectric constant of polyimides.
The branched structure of polyimide resin brings steric hindrance when can accumulate/wind to strand, increase strand
Between spacing, cause the appearance in strand gap indirectly.Not only size is small in these gaps, but also is evenly distributed in the structure,
While not influencing the mechanical performance of polyimide resin, the same function in hole/gap being artificially introduced is played, to dielectric
The reduction of constant provides contribution.After branched structure forms two-dimensional reticular structure, improve poly methylene imine molecular chain in one direction
On it is height-oriented so that lateral mechanical performance is improved, avoid the occurrence of the division of transverse fiber shape.
For these reasons, the invention proposes the polyimides that a kind of polyimides and poly methylene imine homogeneous interpolymer obtain
Compound resin, by the introducing of poly methylene imine unit, to reduce the dielectric constant of polyimides compound resin；It is chained with branch
Structure not only increases molecule interchain voids, further decreases dielectric constant, can also improve the mechanicalness of the poly methylene imine resin of introducing
Can, guarantee that the mechanical performance of polyimides compound resin in all directions reaches the requirement of industrialization product.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to a kind of compound tree of the polyimides for providing low-k
Rouge and preparation method and application.By introducing poly methylene imine unit in polyimide resin, reduce the average dipole of strand
Square reduces the dielectric constant of resin；By introducing branched structure, not only increases strand gap, further decreases dielectric constant,
Also it can improve strand arranging situation of the poly methylene imine unit on laterally and longitudinally two different directions, guarantee all directions all
With certain mechanical performance.The introducing of fluoro-containing group not only brings the effect for reducing dielectric constant, but also makes polyimides point
Sub- chain flexibility increases；Polyimide flex molecule chain element interlinks with poly methylene imine high rigidity molecule chain element, makes point
The flexibility/stiffness of subchain has taken into account processing performance and mechanical performance, thermal linear expansion coefficient in a suitable range
Energy.Such polyimides compound resin with low-k property, will be widely used in electronic information field.
