Abstract
An epoxy resin composition which comprises (a) an epoxy resin and (b) a polyamide resin containing phenolic hydroxy groups which has a structure represented by the formula (1); a method of curing the composition; a varnish, prepreg, or sheet comprising or obtained with the composition; and an epoxy resin hardener which contains as an active ingredient a polyamide resin represented by the formula (1). The epoxy resin composition gives a cured object which has sufficient flexibility even when it is in a thin film form. The cured object further has flame retardancy although it contains none of flame retardants such as halogenated flame retardants and antimony compounds, and is excellent in heat resistance and adhesiveness. The composition is hence extremely useful in a wide range of applications such as a molding material, casting material, laminating material, coating material, adhesive, and resist.
Description
Technical field
The present invention relates to epoxy curing agent, contain the composition epoxy resin and the cured article thereof of this epoxy curing agent.
Background technology
Resins, epoxy is solidified with all solidifying agent, and becomes the character of common mechanical, water tolerance, and resistance to chemical reagents, thermotolerance, electric superior cured articles such as character can be used in tackiness agent, coating, veneer sheet, shaped material, extensive fields such as injection molded material.In the past, the most widely used Resins, epoxy can be enumerated as bisphenol A type epoxy resin.As curing agent for epoxy resin, well-known have acid anhydrides and an amine compound, but in electric, electronic component field from aspect the reliability of thermotolerance etc., use linear phenolic resin (phenol novolac) more.In addition, fire retardant is to use for the purpose of giving the cured article flame retardant resistance.As fire retardant is well-known tetrabromo-bisphenol and epoxide thereof are arranged, or the compound of tetrabromo-bisphenol and bisphenol A type epoxy resin reaction etc. contains the compound of bromine.
But above-mentioned bromine-containing compound is though flame retardant resistance is superior, at material discarded, that may produce contaminate environment when burning.And worry its toxicity equally as the antimony compounds that the flame retardant resistance auxiliary agent uses.Along with the raising of environmental protection consciousness in recent years also improves requirement not halogen-containing in the composition epoxy resin and antimony.In addition, though good with linear phenolic resin as its reliability of cured article of the Resins, epoxy of solidifying agent, the firm shortage snappiness of its cured article.The form of electric in recent years, electronic component, not only have and use, also developed to use and have the laminal object (shaping thing) that polyimide film, PET (polyethylene terephthalate) film or tinsel etc. have flexible laminal substrate with in the past heavy packages or glass fibre plate object as the firm substrate of base material.This shaping thing normally is coated on composition epoxy resin on the laminal substrate with the state of varnish, remove to desolvate, and will solidify through the composition epoxy resin of coating then and makes.The cured article that obtains in this occasion is required to have abundant snappiness and base materials such as polyimide is had high adherence.In addition, with regard to the reliability of electric, electronic component, also require the thermotolerance of cured article.
In addition, as the composition epoxy resin of modified epoxy resin vulnerability in the past, the composition epoxy resin that TOHKEMY 2000-313787 communique discloses contains the aromatic polyamide resin three of Resins, epoxy, phenol resins and tool phenol hydroxyl, and puts down in writing it and have thermotolerance and obdurability.But not mentioned fully for snappiness and flame retardant resistance that can corresponding laminal substrate, think still to be not enough person at that point.
Summary of the invention
The inventor etc. are because above-mentioned practical situation, can obtain not when obtaining solidifying that fire retardant such as brominated system has flame retardant resistance, and thermotolerance, binding property is good, lamellarly also have abundant flexible cured article and further investigate even be configured as in addition, the result has finished the present invention.

Above-mentioned 4 kinds of varnish of the present invention are coated to make dried thickness on the PET film be 50 μ m, and heating makes curing in 1 hour under 180 ℃ temperature, obtain tabular sample after removing the PET film.Any one all can not break resulting sample through bending yet, has sufficient film and forms ability.Cured article carries out flame retardant test according to the UL94-VTM method.These samples are measured second-order transition temperature via DMA.In addition, the varnish that obtains is coated on the polyimide that thickness is 25 μ m (Upilex 25SGA Ube Industries, Ltd system) with spreader, and thickness is that making dried thickness is 10 μ m on the asperities of surface treatment copper foil of 18 μ.100 ℃ removed in dry 10 minutes down desolvate after, the overlapping more same polyimide film or the asperities of surface treatment copper foil on resin layer carry out 1 hour curing reaction under 180 ℃ with the hot plate pressing unit.Observe the degree that various samples are peeled off.The result is shown in table 4.
