Technical Field
The present invention relates to a halogen-free resin composition, and more particularly to a halogen-free resin composition with low dielectric constant.
Background
Due to the rising awareness of global environmental protection and the RoHS environmental regulations implemented by European Union, the copper clad laminate gradually replaces the conventional FR-4 laminate by using lead-free process and halogen-free environment-friendly laminate. In addition to the japanese manufacturers, the continuous introduction of the environmental protection substrate into mobile phones, consumer electronics and notebook computers in the international factories such as samsung electronics, apple, dell, and lotgin will drive the permeability of the environmental protection substrate to grow greatly in recent years.
Moreover, with the rapid development of wireless transmission products and the leap forward of high frequency transmission technology, the materials of the existing epoxy resin and phenolic resin systems have not been able to meet the advanced applications, especially the requirements of high frequency printed circuit boards.
In the prior art of manufacturing a circuit board with a copper clad laminate (or called copper clad laminate), an epoxy resin and a curing agent are used as raw materials of a thermosetting resin composition, a reinforcing material (such as glass fiber cloth) and the thermosetting resin are combined by heating to form a prepreg, and the prepreg and an upper copper foil and a lower copper foil are laminated at high temperature and high pressure. In the prior art, epoxy resin and phenolic (phenolic novolac) resin hardener with hydroxyl (-OH) are generally used as thermosetting resin composition raw materials, the phenolic resin and the epoxy resin are combined to open the ring of the epoxy group to form another hydroxyl group, and the hydroxyl group can improve the dielectric constant and the dielectric loss value, is easy to combine with moisture and increases the hygroscopicity.
There is disclosed a thermosetting resin composition using cyanate ester resin, dicyclopentadienyl epoxy resin, silica and thermoplastic resin, which has low dielectric constant and low dielectric loss. However, this manufacturing method must use flame retardants containing halogen (such as bromine) such as tetrabromocyclohexane, hexabromocyclodecane and 2,4, 6-tris (tribromophenoxy) -1,3, 5-triazabenzene, and these flame retardants containing bromine are likely to cause environmental pollution during product manufacturing, use, and even recycling or discarding. In order to improve the heat resistance, flame retardancy, low dielectric loss, low moisture absorption, high crosslinking density, high glass transition temperature, high adhesion and proper thermal expansion of the copper foil substrate, the materials of the epoxy resin, the hardener and the reinforcing material are selected as main influencing factors.
Therefore, how to develop a material with excellent dielectric properties and meeting the requirements of other characteristics of printed circuit boards, such as high Tg, low thermal expansion coefficient and low water absorption, and apply it to the manufacture of high frequency printed circuit boards is a problem that printed circuit board material suppliers are demanding to solve at present.

The resin compositions of examples 1 to 4 and comparative examples 1 to 5 were mixed in a stirring tank in batches and then placed in an impregnation tank, and then glass fiber cloth was passed through the impregnation tank to adhere the resin compositions to the glass fiber cloth, and then the mixture was heated and baked to be in a semi-cured state to obtain a prepreg.
And (3) taking four semi-cured films and two 18-micron copper foils of the same batch of semi-cured films, overlapping the semi-cured films and the copper foils in sequence, and pressing the semi-cured films and the copper foils at 220 ℃ for 2 hours under a vacuum condition to form a copper foil substrate, wherein the four semi-cured films are cured to form an insulating layer between the two copper foils.
The physical properties of the copper-containing substrate and the copper-free substrate after copper foil etching were measured, and the physical properties were measured by glass transition temperature (Tg), heat resistance of the copper-containing substrate (T288), solder dip test of the copper-containing substrate (solder dip 288 ℃,10 seconds, heat resistance times, S/D), PCT wet dip test of the copper-free substrate (pressing painting at 121 ℃, after 1 hour, solder dip 288 ℃, PCT after 20 seconds, with or without popping up), tension between copper foil and substrate (peelsingstrength, half outer wrapper foil, P/S), dielectric constant (the lower the Dk is, the better the dielectric loss (the lower the Df is), and flame resistance (flame test, UL94, in which the order of superiority and inferiority is V-0> V-1> V-2).
Wherein the results of measuring the physical properties of the substrates prepared from the resin compositions of examples 1 to 4 are shown in table two, and the results of measuring the physical properties of the substrates prepared from the resin compositions of comparative examples 1 to 5 are shown in table four. From the second and fourth tables, it can be seen that, when the resin compositions disclosed in the present invention are added in the proportions of the respective components, substrates having good physical properties can be obtained, and the substrates of comparative examples 1 to 5 have poor physical properties. The results of examples 1 to 3 using different maleic anhydride modified curing agents respectively show that the modified maleic anhydride copolymers of formula 1 and formula 2 in combination with benzoxazine resin can provide better substrate heat resistance (Tg, T288, S/D) and copper foil tensile force (P/S), and the maleic anhydride modified polyimide resin of formula 3 in combination with benzoxazine resin can provide better dielectric constant (Dk) and dielectric loss (Df).
The results of comparative example 1 show that the substrates containing no benzoxazine resin and containing styrene maleic anhydride (EF60) all had poor heat resistance (Tg, T288, S/D, PCT). The results of comparative example 2 show that the substrate containing the benzoxazine resin but not containing the maleic anhydride-modified curing agent was inferior in heat resistance (T288, S/D), copper foil tension (P/S), and dielectric constant (Dk). The results of comparative example 3 show that the substrates containing the modified maleic anhydride copolymers of formulae 1 and 2 but no benzoxazine resin had poor heat resistance (Tg, T288, S/D, PCT), poor copper foil tension (P/S), and poor dielectric constant (Dk) and dielectric loss (Df). The results of comparative example 4 show that the substrates with the maleic anhydride modified polyimide resin of formula 3 and the benzoxazine resin are poor in electrical properties, and the bromine-containing compound used in comparative example 4 as the flame retardant component can achieve the flame resistance rating of UL94V-0, but the halogen-free resin composition disclosed by the invention is environmentally friendly because the halogen (bromine) -containing compound is not used. The results of comparative example 5 show that the resin composition disclosed in the present invention uses the substrate of the maleic anhydride modified polyimide resin of formula 3 in combination with benzoxazine resin, but no flame retardant is added, and the flame resistance rating is inferior to UL94V-2 rating, and does not reach the better V-0 rating.
