Description
Technical field
The present invention relates to a kind of curable resin composition, its film and by solidifying the curable resin composition that described curable resin composition obtains with halogen of flame retardant resistance.In addition, the present invention relates to comprise the curable composites of described curable resin composition and strongthener, by solidifying the cured composite material that described curable composites obtains, comprise the laminate of described cured composite material and tinsel and the tinsel of resin-coating.
Curable resin composition of the present invention has excellent chemical resistant properties after solidifying, dielectric properties, and thermotolerance and flame retardant resistance, and can be in electrician's industry, space and aircraft industry wait and are used as dielectric materials in the field, insulating material, and heat-stable material, structured material, etc.It is particularly useful for the single or double multilayer printed circuit board, flexible print circuit board, and the sequential build circuit card, etc.
Background technology
In recent years, be used for telecommunication, be used for the human consumer and be used for obvious trend miniaturization of industrial field of electronic devices and high density interconnect packing, and so further thermotolerance, dimensional stability and electrical property that improves material therefor of requirement.For example,, used the copper-clad laminate, wherein used thermosetting resin such as phenolic resin and Resins, epoxy as material as printed-wiring board (PWB).Although have good balance quality, the shortcoming of these laminates is to have bad electrical property, especially the dielectric properties in high-frequency region.Have been noted that the polyphenylene oxide as new raw material that can overcome the above problems recently, and attempt they are applied to the copper-clad laminate.
For example, JP-A-61-287739 discloses and has a kind ofly comprised the laminate that the resin combination of polyphenylene oxide and triallyl isocyanurate and/or triallyl cyanurate obtains by curing; JP-B-7-37567 discloses a kind of curable resin composition and laminate by using said composition to obtain that comprises by the polyphenylene oxide of modification with unsaturated carboxylic acid or acid anhydrides and triallyl isocyanurate and/or triallyl cyanurate reaction; And JP-A-64-69628, JP-A-64-69629, JP-A-113425 and JP-A-1-113426 disclose and have comprised three or the polyphenylene oxide of two keys and the curable resin composition of cyanacrylate and/or triallyl cyanurate a kind of comprising.
As the material of the combination that comprises polyphenylene oxide and Resins, epoxy, for example JP-B-64-3223 discloses the curable resin composition that comprises polyphenylene oxide and various Resins, epoxy such as bisphenol A epoxide resin and linear phenolic resin varnish and various solidifying agent such as phenol and amine.In addition, JP-A-2-135216 discloses a kind of comprising by with unsaturated carboxylic acid or anhydride reaction and the polyphenylene oxide of modification, the curable resin composition of polyepoxides and epoxy-curing catalysts, a kind of polyphenylene oxide that comprises melt treatment, the curable resin composition of polyepoxides and epoxy-curing catalysts are disclosed with JP-A-2-166115.
These compositions are used for various electronic materials, common copper-clad laminate, and also in these occasions, the flame retardant resistance of resin is an important performance on the safety point of view of product.So far, as the method that is used to make flame retardant resin, organohalogen compound such as aromatics bromide or epoxy bromide have been used.But organohalogen compound might produce strong toxicity dioxin when they burn, and therefore recently applies stricter regulations at its purposes.
Therefore, in order to deal with these situations, attempted providing flame retardant resistance to the curable resin of described polyphenylene oxide by the compound that uses halogen.As the compound of these halogen, for example metal hydroxides has been proposed, phosphoric acid ester, ammonium polyphosphate.For example, if use metal hydroxides,, be difficult to produce enough flame retardant resistances although this resin keeps the high heat resistance characteristic.In addition, if use phosphoric acid ester, be difficult to when enough flame retardant resistances are provided, keep thermotolerance.In addition, if use ammonium polyphosphate, although provide enough flame retardant resistances when keeping enough flame retardant resistances, weight loss takes place and becomes and can not actually use in impregnated in water the time in solidify material.Therefore, so far, if use the compound of halogen, being difficult to provides enough flame retardant resistances to polyphenylene oxide resin, keeps the thermotolerance characteristic of this resin simultaneously.
The present invention overcomes the above problems, therefore an object of the present invention is to provide a kind of curable resin composition, although not halogen-containing, that is, halogen, it is keeping stable on heating enough flame retardant resistances that has simultaneously.
