Description

Not halogen-containing resin combination

Technical field

The invention relates to a kind of not halogen-containing resin combination.Need not add halogenic ingredient in the said composition and can reach the difficulty combustion standard of UL94V-0, and have excellent thermotolerance and dielectric characteristics.

Background technology

Resins, epoxy has been widely used in as fields such as application, electric insulation, building building materials, solid and lamination product with the security of its easy processibility, height, excellent mechanical properties and chemical property.Wherein, laminated plates with the Resins, epoxy manufacturing, because Resins, epoxy is strong to the adhesion of supporting materials such as glasscloth, fugitive constituent does not take place during sclerosis, mould shrinkage is little, therefore resulting laminated plates has advantages such as use range is wide, physical strength is excellent, electric insulating quality is good, chemical proofing is good, has improved the reliability of lamination sheet material greatly, makes the Resins, epoxy laminated plates be used in large quantities among electric and the electronic product.

In some Application Areas, for example be used for the vehicles such as aircraft, automobile and public transportation, because of directly threatening for the person and life security.Therefore, the difficulty of printed circuit board (PCB) combustion characteristic is absolute necessary.For improving the difficulty combustion characteristic of laminated plates material, must use some to have and isolate the material that flame reduces ignition quality.For the laminated plates that Resins, epoxy/glass fibers is maintained (or organic fibre system), use halogen contained compound, particularly bromated Resins, epoxy and stiffening agent, and cooperation can make the required requirement (as the UL94V-0 grade) of difficulty combustion characteristic conforms of this laminated plates as the difficulty combustion auxiliary agent of the class of antimonous oxide.Usually, Resins, epoxy must contain the bromine content up to 17% to 21%, and is used antimonous oxide or other incombustible agent, just can reach the level of UL94V-0.For example United States Patent (USP) the 5th, 262, No. 491 a kind of compositions that comprise polyphenylene oxide, Resins, epoxy, metal-salt and solidifying agent of announcement, and said composition meets flame retardancy and stable on heating standard, and at high temperature has excellent dielectric characteristics; But the composition that this patent discloses is by the bromine that contains 10% to 30%, and reaches required difficulty combustion and heat-resistant standard, yet, use the incombustible agent or the antimonous oxide of halogen-containing composition, will bring serious harm to the mankind far and away.

On the other hand, in order to satisfy fine rule road and the highdensity requirement that progresses greatly day by day in the printed circuit board (PCB), laminated plates also needs to have more excellent electrical properties, mechanical properties and heat-resisting processibility.With present common FR4 laminated plates, glass tansition temperature after the sclerosis is greatly about about 130 ℃, for the cutting and the boring processing that surpass 200 ℃ in the processing procedure of printed circuit board (PCB), even welding sequence more than 270 ℃, this kind laminated plates material might break or plate bursting in the manufacturing and the course of processing; And, about 12 to 17ppm/ ℃ of this FR4 laminated plates dilation dimension in the plane, for the printed circuit board (PCB) of the existing development trend less than 100 μ m of live width/line-spacing, this laminated plates will be not suitable for using the field at HDI.Therefore, develop energetically at the various laminated plates materials of high heat-resistant quality, high glass tansition temperature of emphasizing.

Therefore, in the not halogen-containing resin combination of the present invention, be to use a kind of phosphorous epoxy resin (particularly side chain type phosphorous epoxy resin), and a kind of stiffening agent with benzoxazine ring-type structure, can be under the condition that need not use the compound that contains halogen or resin, make this resin combination reach the difficulty combustion standard of UL94V-0, and make this resin combination use the resin combination of solidifying agent commonly used to have preferable thermotolerance compared to other; On the other hand, in the not halogen-containing resin combination of the present invention, also comprise polyphenylene oxide resin, make said composition, also have splendid dielectric characteristics except that taking into account simultaneously flame retardancy and the thermotolerance.

Generally speaking, the compound with benzoxazine ring-type structure is to react and make via phenolic compound, amine compound and aldehyde compound.But, the patent of the method for making of multinomial compound with benzoxazine ring-type structure all is to utilize aniline and phenolic compound to react, as United States Patent (USP) the 6th, 005, promptly utilize for No. 064 resol, formaldehyde and aniline to form thermosetting resin with benzoxazine ring-type structure; And the flat 11-50123 patent of Japanese Patent Application also is a kind of method of utilizing bis-phenol, aniline, formalin and making the thermosetting resin of dihydrobenzo oxazines with methyl ethyl ketone as solvent.Yet employed aniline has toxicity and is the chemical substance of decree forbidding in this method for making, so this method for making does not meet the mass-produced demand of industrial community.

The inventor is through extensively and after the further investigation finding, use varsol to react with phenolic compound, aromatic diamine compound and aldehyde compound, can make this reactive system have advantages of higher stability, have toxic aniline reacts except that avoiding using, it is improper also can to reduce Yin Wendu control, make the compound Yin Gaowen that forms benzoxazine ring-type structure and open loop and carry out polymerization once more, gel of avoiding using high polar solvent or protonic solvent to react simultaneously and being produced or caking situation are suitable for industrial mass production.
