Definitions
- Halogen-free resin composition and use thereof
- the present invention relates to the field of copper-clad laminate production technology, and relates to a halogen-free resin composition and use thereof, and particularly to a halogen-free resin composition, a resin glue prepared by using the halogen-free resin composition, and a pre-treatment Dip, laminate and copper clad laminate.
- a conventional copper-clad laminate for printed circuit is mainly made of brominated epoxy resin and realized by bromine.
- epoxy resin circuit boards generally have a high dielectric constant and dielectric loss tangent (dielectric constant is greater than 4, medium).
- the loss tangent is about 0.02), the high frequency characteristics are not sufficient, and it cannot meet the requirements of high frequency signal. Therefore, it is necessary to develop a resin excellent in dielectric properties, that is, a resin having a low dielectric constant and a dielectric loss tangent.
- Thermophilic polybutadiene or copolymer resins of polybutadiene and styrene having good dielectric properties have been studied by those skilled in the art for a long time.
- W097/38564 uses a non-polar styrene and a tetramer of butadiene and divinylbenzene to add a magnesium aluminosilicate filler, a circuit board made of glass fiber cloth as a reinforcing material, although excellent in dielectric properties,
- the heat resistance of the substrate is very poor, the glass transition temperature is only about 100 ° C, and the thermal expansion coefficient is large, which is difficult to meet the high temperature (above 240 ° C) requirements of the lead-free process in the PCB manufacturing process.
- US5571609 uses a low molecular weight 1,2-polybutadiene resin or polyisobutadiene having a molecular weight of less than 5,000 and a copolymer of high molecular weight butadiene and styrene, and adds a large amount of silicon micropowder as a filler to the glass.
- the circuit board made of the fiber cloth as a reinforcing material has excellent dielectric properties, but the high molecular weight component is used in the patent to improve the tackiness of the prepreg, so that the process performance of the process for producing the prepreg is deteriorated; and because the entire resin
- the ratio of the rigid structure benzene ring in the resin molecule of the system is small, and the segment after crosslinking is mostly composed of a methylene group having a very low rigidity, so that the produced sheet has poor rigidity and low bending strength.
- US6569943 uses a liquid-modified polybutadiene resin with a vinyl group at the end of the molecule, a large amount of low molecular weight monomer (dibromostyrene) as a curing agent and diluent, and a circuit made of glass fiber cloth impregnated
- the substrate has good dielectric properties, but since the resin system is liquid at normal temperature and cannot be made into a non-stick prepreg, it is difficult to use a common prepreg process when the sheet is pressed and formed, and the process operation is difficult.
- CN101544841B uses a hydrocarbon resin having a molecular weight of 11,000 or less and a vinyl content of 60% or more.
- allyl modified phenolic resin is used to improve the tackiness of the prepreg, and the peel strength is improved.
- the heat resistance after curing of the system is low, and the copper clad laminate has delamination failure during PCB processing. The risk is higher.
- the system based on hydrocarbon resin has low adhesion to metal and low heat resistance of the system, which brings a high probability of failure in the PCB processing process downstream of the copper clad laminate.
- halogen-free resin composition which has a lower dielectric constant and dielectric properties using prepregs and laminates made of the halogen-free resin composition. Loss tangent, high peel strength, high glass transition temperature, excellent heat resistance and excellent flame retardant effect.
- a halogen-free resin composition based on parts by weight of an organic solid, comprising:
- the content of the component (A) allyl-modified benzoxazine resin is, for example, 42 parts by weight, 44 parts by weight, 46 parts by weight, 48 parts by weight, 50 parts by weight, 52 parts by weight, 54 parts by weight, 56 Parts by weight, 58 parts by weight, 60 parts by weight, 62 parts by weight, 64 parts by weight, 66 parts by weight, 68 parts by weight, 70 parts by weight, 72 parts by weight, 74 parts by weight, 76 parts by weight or 78 parts by weight.
- the content of the component (B) hydrocarbon resin is, for example, 11 parts by weight, 12 parts by weight, 13 parts by weight, 14 parts by weight, 15 parts by weight, 16 parts by weight, 17 parts by weight, 18 parts by weight or 19 parts by weight.
- the content of the component (C) allyl-modified polyphenylene ether resin is, for example, 12 parts by weight, 14 parts by weight, 16 parts by weight, 18 parts by weight, 20 parts by weight, 22 parts by weight, 26 parts by weight, 28 parts by weight, 30 parts by weight, 32 parts by weight, 34 parts by weight, 36 parts by weight or 38 parts by weight.
- the content of the component (D) initiator is, for example, 0.03 parts by weight, 0.05 parts by weight, 0.08 parts by weight, 0.1 parts by weight, 0.4 parts by weight, 0.7 parts by weight, 1 part by weight, 1.3 parts by weight, 1.5 parts by weight, 1.7. Parts by weight, 1.9 parts by weight, 2.1 parts by weight, 2.3 parts by weight, 2.5 parts by weight, 2.7 parts by weight or 2.9 parts by weight.
- the invention mainly comprises an allyl modified benzoxazine resin, and provides excellent heat resistance and excellent electrical properties for the system, and is combined with an allyl modified polyphenylene ether resin and a hydrocarbon resin having excellent electrical properties. Improve the electrical properties of the curing system.
- Each component in the resin composition contains a carbon-carbon double bond. Under the action of heat during the curing reaction, the initiator decomposes the active radical, and under the action of the active radical, the double bond of each component is free radical.
- the mechanism of polymerization produces crosslinked macromolecular polymers. No polar groups such as hydroxyl groups are formed throughout the polymerization process, and the polymerization product retains the excellent dielectric properties and dielectric loss values of the raw materials to the utmost.
- the adhesive sheet prepared by using the halogen-free high-frequency resin composition of the present invention has a low dielectric constant and dielectric loss tangent, a high peel strength, a high glass transition temperature, and excellent heat resistance. Good flame retardant effect; copper clad laminate made of the adhesive sheet has low dielectric constant and dielectric loss tangent, high peel strength, high glass transition temperature, and excellent Heat resistance, better flame retardant effect.
- the component (A) allyl modified benzoxazine resin is selected from the group consisting of allyl modified bisphenol A type benzoxazine resin, olefin Modified bisphenol F type benzoxazine resin, allyl modified dicyclopentadiene phenol type benzoxazine resin, allyl modified bisphenol S type benzoxazine resin or diamine type benzo Any one or a mixture of at least two of the oxazine resins.
- the mixture is, for example, a mixture of allyl modified bisphenol A type benzoxazine resin and allyl modified bisphenol F type benzoxazine resin, allyl modified dicyclopentadiene phenol type benzoxazole Pyridine resin and allyl modified bisphenol Mixture of S-type benzoxazine resin, mixture of diamine benzoxazine resin, allyl modified bisphenol A benzoxazine resin and allyl modified bisphenol F benzoxazine resin , a mixture of allyl modified dicyclopentadiene phenol type benzoxazine resin, allyl modified bisphenol S type benzoxazine resin and diamine type benzoxazine resin.
- the hydrocarbon resin is a hydrocarbon resin having a number average molecular weight of 11,000 or less and a vinyl content of more than 60%, which is a liquid at room temperature.
- the allyl-modified polyphenylene ether resin is an allyl-modified polyphenylene ether resin having a number average molecular weight of 5,000 or less, which ensures free radicals with other resins.
- the polymerization reaction finally produces a uniform modified resin system, which reduces the probability of phase separation in the system and avoids a negative impact on the electrical properties of the system.
