Description

本発明は、電子機器に用いられる樹脂組成物及びそれを用いたプリプレグ、積層板、配線板に関する。   The present invention relates to a resin composition used for an electronic device, and a prepreg, a laminate, and a wiring board using the same.

通常の積層板は、エポキシ樹脂を主剤とした樹脂組成物とガラス織布とを硬化・一体成形したものが一般的である。エポキシ樹脂は絶縁性や耐熱性、コストなどのバランスが優れるが、燃焼し易いという欠点を有する。このため、積層板の難燃化は必須であり、従来ブロム系難燃剤が用いられていた(特許文献1参照)。しかし、環境意識の高まりから燃焼時に環境に好ましくない物質を発生する可能性がある材料は電子部品も含めて規制する動きが活発になっている。このため、水酸化アルミニウムや水酸化マグネシウム等の水酸化物(特許文献2参照)、リン酸エステル等のリン化合物(特許文献3参照)、メラミン等の窒素化合物が難燃剤(特許文献4参照)として使用されている。しかしながら、水酸化物は多量に配合しないと難燃機能が発現しない、リン化合物は腐食性を有する、窒素化合物は難燃効果が低いなどの問題も知られている。また、ケイ酸塩、炭酸塩、金属酸化物等も難燃効果を発現することが知られている(特許文献5参照)。   A typical laminate is generally obtained by curing and integrally molding a resin composition mainly composed of an epoxy resin and a glass woven fabric. Epoxy resins have an excellent balance of insulation, heat resistance, cost, etc., but have the disadvantage of being easy to burn. For this reason, the flame retarding of a laminated board is indispensable, and the brominated flame retardant was conventionally used (refer patent document 1). However, due to increasing environmental awareness, there is an active movement to regulate materials including electronic components that may generate undesirable substances for the environment during combustion. For this reason, hydroxides such as aluminum hydroxide and magnesium hydroxide (see Patent Document 2), phosphorus compounds such as phosphate esters (see Patent Document 3), and nitrogen compounds such as melamine are flame retardants (see Patent Document 4). It is used as However, there are also known problems that the flame retardant function does not appear unless a large amount of hydroxide is blended, the phosphorus compound is corrosive, and the nitrogen compound has a low flame retardant effect. Silicates, carbonates, metal oxides, and the like are also known to exhibit a flame retardant effect (see Patent Document 5).

本発明で用いる発泡剤は、加熱分解して発生するガスで多環式構造を有する樹脂から発生する燃焼ガスを希釈して難燃効果を発現すると考えられる。したがって、多環式構造を有する樹脂から発生する燃焼ガスより燃焼性の低いガスを発生すればどのような発泡剤を用いても良いが、不燃性ガスであるとより好ましく、窒素、二酸化炭素、水蒸気のいずれか1つ以上を含有するガスを発生する発泡剤が特に好ましい。また、発泡剤の形状はどのような形状でもよいが、樹脂の流動性に対する影響を低減するために、球状であることが好ましく、溶剤に溶解できる発泡剤がさらに好ましい。また、アミノ基を有する発泡剤は、アンモニウム化することで熱分解温度を高くすることができる、樹脂と反応しても熱分解温度を高くできるために好ましい。なお、アミノ基を有する発泡剤としては、例えば、化合物(材料)として、ヒドラゾカルボンアミド、アゾジカルボンアミドなどが挙げられる。   The foaming agent used in the present invention is considered to exhibit a flame retardant effect by diluting a combustion gas generated from a resin having a polycyclic structure with a gas generated by thermal decomposition. Therefore, any blowing agent may be used as long as it generates a gas that is less flammable than a combustion gas generated from a resin having a polycyclic structure, but it is more preferably an incombustible gas, such as nitrogen, carbon dioxide, A blowing agent that generates a gas containing any one or more of water vapor is particularly preferable. The foaming agent may have any shape, but in order to reduce the influence on the fluidity of the resin, the foaming agent is preferably spherical, and more preferably a foaming agent that can be dissolved in a solvent. Moreover, the foaming agent which has an amino group is preferable because it can raise a thermal decomposition temperature by ammonium-izing, and can raise a thermal decomposition temperature even if it reacts with resin. Examples of the foaming agent having an amino group include hydrazocarbonamide and azodicarbonamide as compounds (materials).

発泡剤のガス発生量は50ml/g以上であれば好ましく、70ml/g以上であればより好ましく、90ml/g以上であれば特に好ましい。発泡剤のガス発生量が50ml/g未満の場合、難燃効果が不十分なため、好ましくない。また、発泡剤のガス発生量は400ml/g以下であれば好ましく、350ml/g以下であればより好ましく、300ml/g以下であれば特に好ましい。発泡剤のガス発生量が400ml/gを超える場合、耐熱性等が低下するため、好ましくない。   The gas generation amount of the blowing agent is preferably 50 ml / g or more, more preferably 70 ml / g or more, and particularly preferably 90 ml / g or more. When the amount of gas generated by the foaming agent is less than 50 ml / g, the flame retardant effect is insufficient, which is not preferable. Further, the gas generation amount of the foaming agent is preferably 400 ml / g or less, more preferably 350 ml / g or less, and particularly preferably 300 ml / g or less. When the gas generation amount of the foaming agent exceeds 400 ml / g, heat resistance and the like are lowered, which is not preferable.

使用できる発泡剤の市販品としては、例えば、セルマイク142(ガス発生量90ml/g)、セルマイクC−2(ガス発生量270ml/g)、セルマイク266(ガス発生量120ml/g)、セルマイク306(ガス発生量100ml/g)、セルマイク417(ガス発生量90ml/g)、セルマイク494(ガス発生量120ml/g)、セルマイク496(ガス発生量110ml/g)(すべて三協化成株式会社製、商品名)などが挙げられる。   Examples of commercially available foaming agents that can be used include cell microphone 142 (gas generation amount 90 ml / g), cell microphone C-2 (gas generation amount 270 ml / g), cell microphone 266 (gas generation amount 120 ml / g), cell microphone 306 ( Gas generation amount 100 ml / g), cell microphone 417 (gas generation amount 90 ml / g), cell microphone 494 (gas generation amount 120 ml / g), cell microphone 496 (gas generation amount 110 ml / g) (all manufactured by Sankyo Kasei Co., Ltd., products) Name).

The range of parts is preferable, 0.7 to 5 parts by mass is more preferable, and 1 to 4 parts by mass is particularly preferable. When the foaming agent is less than 0.50 parts by mass with respect to 100 parts by mass of the resin having a polycyclic structure, the flame retardant effect is poor, and when it exceeds 10 parts by mass, the resin characteristics of the polycyclic structure may be deteriorated. . In order to uniformly disperse the foaming agent, it is effective to use a dispersing device such as a raking machine, a homogenizer, a bead mill, or a nanomizer, or a pulverizing device.

本発明の多環式構造を有する樹脂と発泡剤を混合(分散)、溶解するため、溶剤を加えることが好ましい。溶剤は、多環式構造を有する樹脂と発泡剤を分散、溶解できればどのようなものでもよいが、特にアセトン、メチルエチルケトン、メチルイソブチルケトン、トルエン、キシレン、酢酸エチル、N、N−ジメチルホルムアミド、N、N−ジメチルアセトアミド、エタノール、エチレングリコールモノメチルエーテル、プロピレングリコールモノメチルエーテルアセテート等が溶解性に優れ、好ましい。これらの溶剤の配合量は、多環式構造を有する樹脂と発泡剤の溶解、分散ができればどのような量でもよいが、多環式構造を有する樹脂と発泡剤の総量100質量部に対して、30〜300質量部の範囲が好ましく、50〜200質量部の範囲がさらに好ましい。また、上記の溶剤は、組み合わせて用いても構わない。   In order to mix (disperse) and dissolve the resin having a polycyclic structure of the present invention and the foaming agent, it is preferable to add a solvent. The solvent may be any solvent as long as it can disperse and dissolve the resin having a polycyclic structure and the foaming agent. In particular, acetone, methyl ethyl ketone, methyl isobutyl ketone, toluene, xylene, ethyl acetate, N, N-dimethylformamide, N N-dimethylacetamide, ethanol, ethylene glycol monomethyl ether, propylene glycol monomethyl ether acetate and the like are preferable because of excellent solubility. The amount of these solvents may be any amount as long as the resin having a polycyclic structure and the foaming agent can be dissolved and dispersed, but the total amount of the resin having the polycyclic structure and the foaming agent is 100 parts by mass. The range of 30-300 mass parts is preferable, and the range of 50-200 mass parts is more preferable. Moreover, you may use said solvent in combination.

本発明の樹脂組成物は、さらに無機充填剤を配合しても構わないし、添加剤を添加してもかまわない。無機充填剤としては、シリカ、アルミナ、水酸化アルミニウム、炭酸カルシウム、クレイ、タルク、窒化珪素、窒化ホウ素、酸化チタン、チタン酸バリウム、チタン酸鉛、チタン酸ストロンチウム等を使用することができ、特に水酸化アルミニウムが好ましい。無機充填剤の配合量としては、多環式構造を有する樹脂と発泡剤の総量100質量部に対して、300質量部以下とすることが、好ましく、200質量部以下にすることが本発明の樹脂組成物(多層配線板用材料)が均一でかつ良好な取扱性を得るためにより好ましい。また、0.5質量部以上とすることが好ましく、1質量部以上とすることがより好ましい。無機充填剤を均一に分散させるため、らいかい機、ホモジナイザー、ビーズミル、ナノマイザー等を用いることが有効である。   The resin composition of the present invention may further contain an inorganic filler or an additive. As the inorganic filler, silica, alumina, aluminum hydroxide, calcium carbonate, clay, talc, silicon nitride, boron nitride, titanium oxide, barium titanate, lead titanate, strontium titanate, etc. can be used. Aluminum hydroxide is preferred. The blending amount of the inorganic filler is preferably 300 parts by mass or less, preferably 200 parts by mass or less, with respect to 100 parts by mass of the total amount of the resin having a polycyclic structure and the foaming agent. The resin composition (multilayer wiring board material) is more preferable in order to obtain uniform and good handling properties.

(表1、表2中の空欄は、配合無しを示す。)
Figure 2010222569
(The blanks in Table 1 and Table 2 indicate no blending.)

表1の実施例1、2の比較から、発泡剤配合量が増えるに従って、平均燃焼時間が短くなっていくことがわかる。また、表1の実施例1,3の比較から、ガス発生量が多い発泡剤を使用した場合ほど燃焼時間が短くなっていくことがわかる。実施例の平均燃焼時間が6.1〜6.8s(秒)であるのに対し、表2の比較例1、2の平均燃焼時間が8.3〜8.5s(秒)であり実施例に比較して長かった(悪かった)。すなわち、比較例2に示したように、多環式構造を有する樹脂(エポキシ樹脂及び硬化剤)100質量部に対し、発泡剤配合量(セルマイク142)が0.3質量部程度である場合は、発泡剤配合による難燃効果が乏しいことが判る。したがって、多環式化合物(多環式構造を有する樹脂)の難燃性向上には一定量以上の発泡剤の配合が有効であることがわかる。
本発明によれば、多環式構造を有する樹脂に一定量以上の発泡剤を配合することで、難燃性の高い樹脂組成物を得ることができる。
From the comparison of Examples 1 and 2 in Table 1, it can be seen that the average combustion time decreases as the blending amount of the blowing agent increases. Moreover, it can be seen from the comparison between Examples 1 and 3 in Table 1 that the combustion time becomes shorter as the foaming agent having a larger gas generation amount is used. While the average burning time of the example is 6.1 to 6.8 s (seconds), the average burning time of Comparative Examples 1 and 2 in Table 2 is 8.3 to 8.5 s (second). It was longer (bad) than That is, as shown in Comparative Example 2, when 100 parts by mass of the resin having a polycyclic structure (epoxy resin and curing agent), the amount of foaming agent (cell microphone 142) is about 0.3 parts by mass It can be seen that the flame retardant effect by blending the foaming agent is poor. Therefore, it can be seen that blending of a certain amount or more of the foaming agent is effective for improving the flame retardancy of the polycyclic compound (resin having a polycyclic structure).
According to the present invention, a resin composition having high flame retardancy can be obtained by blending a certain amount or more of a foaming agent with a resin having a polycyclic structure.
