Description
本開示はガス発生剤組成物に関する。 The present disclosure relates to gas generating agent compositions.
車両に搭載されるエアバッグ装置等の車両安全装置に使用される、ガス発生剤組成物を使用するインフレータにおいて、製品の信頼性を確保する試みがなされている。例えば、ガス発生剤組成物の燃焼温度を下げ、着火性を向上させるとともに、圧力指数を小さくする試みが行われている（特許文献１）。なお、ガス発生剤組成物の燃焼速度は、インフレータ内の圧力変動により、下式のように圧力指数ｎのべき乗の幅で変動することが知られている。
特許文献１に記載の発明は、メラミンシアヌレートとニトログアニジンの比率を特定範囲に設定することを解決手段として課題を解決している。
Attempts have been made to ensure product reliability in inflators that use gas generating agent compositions used in vehicle safety devices such as airbag devices mounted on vehicles. For example, attempts have been made to lower the combustion temperature of the gas generating agent composition, improve the ignitability, and reduce the pressure index (Patent Document 1). It is known that the combustion rate of the gas generating agent composition fluctuates in the range of the power of the pressure index n as shown in the following equation due to the pressure fluctuation in the inflator.
The invention described in
ガス発生剤組成物の特性の一つに燃焼速度がある。ガス発生剤組成物の燃焼速度が低い場合、その欠点を補うために、ガス発生剤組成物を成形する際に形状を小さくする必要がある。ガス発生剤組成物の成形時の形状を小さくする場合、製造工程が煩雑になることがある。また、燃焼速度が低いガス発生剤組成物を、早期展開が要求されるインフレータ用のガス発生剤として用いることはできない。それに加え、ガス発生剤組成物の着火性についても良好な特性を有することが求められている。
これらのことから、本開示は、高い燃焼速度を有し、着火性が良いガス発生剤組成物の提供を課題とする。
One of the characteristics of the gas generating agent composition is the combustion rate. When the combustion rate of the gas generating agent composition is low, it is necessary to reduce the shape when molding the gas generating agent composition in order to make up for the shortcomings. When the shape of the gas generating agent composition at the time of molding is reduced, the manufacturing process may be complicated. Further, a gas generating agent composition having a low combustion rate cannot be used as a gas generating agent for an inflator that requires early development. In addition, the gas generating agent composition is required to have good ignitability.
From these facts, it is an object of the present disclosure to provide a gas generating agent composition having a high combustion rate and good ignitability.
本発明者らは、上記課題を解決すべく鋭意研究を重ねた結果、ガス発生剤組成物の添加物として塩基性炭酸マグネシウムを用いるとともに、その平均粒子径が所定範囲のものを使用することで、高い燃焼速度と短い着火時間を有するガス発生剤組成物を得ることができることを見出した。
特に、燃料として硝酸グアニジンを含み、酸化剤として塩基性金属硝酸塩を含むガス発生剤組成物において、塩基性炭酸マグネシウムを添加した場合にはガス発生剤組成物の燃焼速度が高くなることが分かった。また、上記のガス発生剤組成物における塩基性炭酸マグネシウムの平均粒子径が所定の範囲である場合には、高い燃焼速度と良好な着火性を有することが分かった。なお、本明細書において、着火性が良好であることは着火時間が短いことと同義である。
As a result of diligent research to solve the above problems, the present inventors have decided to use basic magnesium carbonate as an additive for the gas generating agent composition and to use one having an average particle size within a predetermined range. , It has been found that a gas generating agent composition having a high burning rate and a short ignition time can be obtained.
In particular, in a gas generating agent composition containing guanidine nitrate as a fuel and a basic metal nitrate as an oxidizing agent, it was found that the combustion rate of the gas generating agent composition increases when basic magnesium carbonate is added. .. It was also found that when the average particle size of the basic magnesium carbonate in the above gas generating agent composition is within a predetermined range, it has a high combustion rate and good ignitability. In the present specification, good ignitability is synonymous with short ignition time.

本開示の実施形態によれば、高い燃焼速度を有し、着火性が良いガス発生剤組成物を提供できる。 According to the embodiment of the present disclosure, it is possible to provide a gas generating agent composition having a high combustion rate and good ignitability.
以下、本開示を具体的な実施形態に基づき説明する。 Hereinafter, the present disclosure will be described based on specific embodiments.
（ａ）燃料
本開示の実施形態にかかる（ａ）成分の燃料は、硝酸グアニジンを含む。硝酸グアニジンは、分子中に酸素を含有するため、酸化剤成分の配合量を低減でき、また良好な熱安定性を有し、更には低コスト、燃焼時の高いガス化率が期待できる等のメリットがある。
本開示において、硝酸グアニジンは、取り扱いが容易であることから粉末状若しくは顆粒状であることが好ましく、その５０％粒径の下限としては、通常５μｍ以上、好ましい一態様では１０μｍ以上であり、上限としては、通常８０μｍ以下、好ましい一態様は５０μｍ以下である。なお、硝酸グアニジンの５０％粒径は、大き過ぎるとガス発生剤組成物成形体の強度が低下する一方で、小さ過ぎると粉砕に多大なコストを必要とする。なお、本開示において５０％粒径とは、測定粒子数基準の５０％粒径を意味し、例えばレーザー回折・散乱法等で測定できる。
(A) Fuel The fuel of the component (a) according to the embodiment of the present disclosure contains guanidine nitrate. Since guanidine nitrate contains oxygen in its molecule, the amount of oxidant component can be reduced, it has good thermal stability, and it can be expected to have low cost and high gasification rate during combustion. There are merits.
In the present disclosure, guanidine nitrate is preferably in the form of powder or granules because it is easy to handle, and the lower limit of the 50% particle size is usually 5 μm or more, and in one preferred embodiment, 10 μm or more, and the upper limit thereof. Usually, it is 80 μm or less, and one preferred embodiment is 50 μm or less. If the 50% particle size of guanidine nitrate is too large, the strength of the gas generating agent composition molded body is lowered, but if it is too small, a large cost is required for pulverization. In the present disclosure, the 50% particle size means a 50% particle size based on the number of measured particles, and can be measured by, for example, a laser diffraction / scattering method.
本開示の実施形態にかかるガス発生剤組成物中に占める硝酸グアニジンの含有率（配合割合）の下限としては、通常２０質量％以上であり、好ましい一態様では３０質量％以上であり、上限としては、通常６０質量％以下、好ましい一態様では５５質量％以下である。硝酸グアニジンの含有率（配合割合）が２０質量％未満では、ガス発生剤組成物１００ｇ当たりの発生ガスモル数が減少し、酸素過剰で窒素酸化物の発生が増加する傾向にある。一方、硝酸グアニジンの含有率（配合割合）が６０質量％を超えると酸化剤成分が不足
するために有害な一酸化炭素が多く発生する傾向にある。
さらに本発明の課題を解決できる範囲で公知の他の燃料を含有することもできる。
公知の他の燃料としては、５－アミノテトラゾール、ビテトラゾールアンモニウム塩を含むテトラゾール類化合物；グアニジン硝酸塩、ジシアンジアミドを含むグアニジン類化合物（ニトログアニジンは除く）；メラミン、トリメチロールメラミン、アルキル化メチロールメラミン、アンメリン、アンメランド、メラミンの硝酸塩、メラミンの過塩素酸塩、トリヒドラジノトリアジン、メラミンのニトロ化化合物を含むトリアジン類化合物から選ばれる１種以上を挙げることができる。
The lower limit of the content (blending ratio) of guanidine nitrate in the gas generating agent composition according to the embodiment of the present disclosure is usually 20% by mass or more, and in a preferred embodiment, it is 30% by mass or more, as an upper limit. Is usually 60% by mass or less, and in a preferred embodiment, 55% by mass or less. When the content (blending ratio) of guanidine nitrate is less than 20% by mass, the number of generated gas moles per 100 g of the gas generating agent composition tends to decrease, and the generation of nitrogen oxides tends to increase due to excess oxygen. On the other hand, when the content (blending ratio) of guanidine nitrate exceeds 60% by mass, a large amount of harmful carbon monoxide tends to be generated due to the shortage of the oxidant component.
Further, other known fuels can be contained as long as the problems of the present invention can be solved.
Other known fuels include tetrazole compounds containing 5-aminotetrazole and bitetrazole ammonium salts; guanidine compounds containing guanidine nitrate and dicyandiamide (excluding nitroguanidine); melamine, trimethylol melamine, alkylated methylol melamine, One or more selected from triazine compounds including ammeline, ammeline, melamine nitrate, melamine perchlorate, trihydrazinotriazine, and melamine nitrate compounds can be mentioned.
（ｂ）酸化剤
本開示の実施形態にかかる（ｂ）成分の酸化剤は、塩基性金属硝酸塩及び必要に応じて他の酸化剤を含むものである。（ｂ）成分として塩基性金属硝酸塩を使用することで、燃焼温度を低下させることができる。
塩基性金属硝酸塩は、塩基性硝酸銅、塩基性硝酸コバルト、塩基性硝酸亜鉛及び塩基性硝酸マンガンから選ばれる１種以上を挙げることができ、これらの中でも塩基性硝酸銅が好ましい。他の酸化剤としては、金属硝酸塩、硝酸アンモニウム、金属過塩素酸塩、過塩素酸アンモニウム、金属亜硝酸塩、金属塩素酸塩等を挙げることができる。
酸化剤の含有量は、通常は当該ガス発生剤組成物に対して、好ましい一態様では３５質量％以上、７５質量％以下の範囲であり、特に発生ガス中の一酸化炭素と窒素酸化物濃度を低減させるために、別の好ましい一態様では４０質量％以上、７５質量％以下の範囲に設定することがより好ましい。
(B) Oxidizing Agent The oxidizing agent of the component (b) according to the embodiment of the present disclosure contains a basic metal nitrate and, if necessary, another oxidizing agent. By using the basic metal nitrate as the component (b), the combustion temperature can be lowered.
Examples of the basic metal nitrate include one or more selected from basic copper nitrate, basic cobalt nitrate, basic zinc nitrate and basic manganese nitrate, and among these, basic copper nitrate is preferable. Examples of other oxidizing agents include metal nitrate, ammonium nitrate, metal perchlorate, ammonium perchlorate, metal nitrite, metal chlorate and the like.
The content of the oxidant is usually in the range of 35% by mass or more and 75% by mass or less in a preferable embodiment with respect to the gas generating agent composition, and particularly the carbon monoxide and nitrogen oxide concentrations in the generated gas. In another preferred embodiment, it is more preferable to set it in the range of 40% by mass or more and 75% by mass or less.
（ｃ）バインダー
本開示の実施形態にかかる（ｃ）成分のバインダーとしては、カルボキシメチルセルロース（ＣＭＣ）、カルボキシメチルセルロースナトリウム塩（ＣＭＣＮａ）、カルボキシメチルセルロースカリウム塩、カルボキシメチルセルロースアンモニウム塩、酢酸セルロース、セルロースアセテートブチレート（ＣＡＢ）、エチルセルロース（ＥＣ）、ヒドロキシエチルセルロース（ＨＥＣ）、微結晶性セルロース、ポリアクリルヒドラジド、アクリルアミド・アクリル酸金属塩共重合体、ポリアクリルアミド・ポリアクリル酸エステル化合物の共重合体、アクリルゴム及びシリコーンから選ばれる１種以上を挙げることができる。これらの中でもＣＭＣＮａが好ましい。
本開示の実施形態にかかるガス発生剤組成物中における（ｃ）成分のバインダーの含有量の下限としては、通常０．１質量％以上、好ましい一態様では１質量％以上であり、上限としては、通常１０質量％以下、好ましい一態様では８質量％以下である。
(C) Binder The binder of the component (c) according to the embodiment of the present disclosure includes carboxymethyl cellulose (CMC), carboxymethyl cellulose sodium salt (CMCNa), carboxymethyl cellulose potassium salt, carboxymethyl cellulose ammonium salt, cellulose acetate, cellulose acetate buty. Rate (CAB), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), microcrystalline cellulose, polyacrylic hydrazide, acrylamide / acrylic acid metal salt copolymer, polyacrylamide / polyacrylic acid ester compound copolymer, acrylic rubber And one or more selected from silicone. Among these, CMCNa is preferable.
The lower limit of the content of the binder of the component (c) in the gas generating agent composition according to the embodiment of the present disclosure is usually 0.1% by mass or more, preferably 1% by mass or more in one preferred embodiment, and the upper limit is. , Usually 10% by mass or less, preferably 8% by mass or less in one embodiment.
（ｄ）塩基性炭酸マグネシウム
本開示の実施形態にかかる（ｄ）成分の塩基性炭酸マグネシウムは、ガス発生剤組成物の高い燃焼速度を確保するために添加するものである。
本開示の実施形態にかかるガス発生剤組成物中における（ｄ）塩基性炭酸マグネシウムの含有量は、好ましい一態様では１１質量％以下であり、別の好ましい態様では１０質量％以下であり、別の好ましい一態様では６質量％以下であり、別の好ましい一態様では５質量％未満、さらに別の好ましい一態様では２質量％未満である。
ガス発生剤の燃焼時に塩基性炭酸マグネシウムの塩基により、燃焼反応の律速過程を促進させることで着火性を向上させることができる。特に塩基性炭酸マグネシウムは比較的少量でもガス発生剤組成物全体のｐＨをコントロールできるため、例えば６質量％以下の含有量であっても、十分効果が得られる。
一方、塩基性炭酸マグネシウムの含有量が１１質量％を超えると、ガス発生剤組成物の燃焼速度と着火性が低下することがある。
一方、ガス発生剤組成物の着火性を良好に保つ観点から、塩基性炭酸マグネシウムの含有量は、好ましい一態様では０．１質量％以上である。
本開示の実施形態にかかる塩基性炭酸マグネシウムは市販されているものを用いることができる。
本開示の実施形態にかかる塩基性炭酸マグネシウムの平均粒子径は、１２μｍ以下である。さらに好ましい一態様では１１μｍ以下である。スケールアップ時に塩基性炭酸マグネシウムの量が少量でも着火性向上の効果を安定的に得るためには、燃料及び酸化剤と塩基性炭酸マグネシウムの接触を上げる必要がある。そのため、燃料及び酸化剤と同等以下の平均粒子径である、１２μｍ以下の平均粒子径を有することで、ガス発生剤組成物の着火性、特に低温環境での着火性が向上する。一方、該塩基性炭酸マグネシウムの平均粒子径は、通常、５μｍ以上であり、好ましい一態様では８μｍ以上である。
ガス発生剤組成物の燃焼は外部環境の影響を受けやすく、一般的に低温環境では常温・高温と比較すると着火や燃焼継続が不利になる。温度による性能差を小さくするためにも、低温環境での着火性の向上は重要である。
塩基性炭酸マグネシウムの平均粒子径は、レーザー回折・散乱法を利用する粒度分布測定装置により測定することができる。具体的には、精密粒度分布測定装置（マイクロトラック・ベル株式会社製のマイクロトラックＨＲＡ、３０００IIなど）を用いて測定することができる
塩基性炭酸マグネシウムの平均粒子径は、その製造時、例えば、炭酸化法による反応晶析により塩基性炭酸マグネシウムを得る場合は、原料として用いる水酸化マグネシウムの初濃度と反応温度を制御することにより調整することができる。
(D) Basic Magnesium Carbonate The basic magnesium carbonate component (d) according to the embodiment of the present disclosure is added in order to ensure a high combustion rate of the gas generating agent composition.
The content of (d) basic magnesium carbonate in the gas generating agent composition according to the embodiment of the present disclosure is 11% by mass or less in a preferred embodiment and 10% by mass or less in another preferred embodiment. In one preferred embodiment of the above, it is 6% by mass or less, in another preferred embodiment it is less than 5% by mass, and in yet another preferred embodiment it is less than 2% by mass.
The ignitability can be improved by accelerating the rate-determining process of the combustion reaction by the base of basic magnesium carbonate at the time of combustion of the gas generating agent. In particular, since the pH of the entire gas generating agent composition can be controlled even with a relatively small amount of basic magnesium carbonate, a sufficient effect can be obtained even if the content is, for example, 6% by mass or less.
On the other hand, if the content of basic magnesium carbonate exceeds 11% by mass, the combustion rate and ignitability of the gas generating agent composition may decrease.
On the other hand, from the viewpoint of maintaining good ignitability of the gas generating agent composition, the content of basic magnesium carbonate is 0.1% by mass or more in a preferred embodiment.
As the basic magnesium carbonate according to the embodiment of the present disclosure, commercially available ones can be used.
The average particle size of basic magnesium carbonate according to the embodiment of the present disclosure is 12 μm or less. In a more preferable aspect, it is 11 μm or less. In order to stably obtain the effect of improving ignitability even if the amount of basic magnesium carbonate is small at the time of scale-up, it is necessary to increase the contact between the fuel and the oxidizing agent and the basic magnesium carbonate. Therefore, having an average particle size of 12 μm or less, which is an average particle size equal to or less than that of the fuel and the oxidant, improves the ignitability of the gas generating agent composition, particularly in a low temperature environment. On the other hand, the average particle size of the basic magnesium carbonate is usually 5 μm or more, and in one preferred embodiment, it is 8 μm or more.
Combustion of the gas generating agent composition is easily affected by the external environment, and in general, ignition and continuous combustion are disadvantageous in a low temperature environment as compared with normal temperature and high temperature. It is important to improve the ignitability in a low temperature environment in order to reduce the difference in performance due to temperature.
The average particle size of basic magnesium carbonate can be measured by a particle size distribution measuring device using a laser diffraction / scattering method. Specifically, the average particle size of basic magnesium carbonate that can be measured using a precision particle size distribution measuring device (Microtrac HRA, 3000II manufactured by Microtrac Bell Co., Ltd.) can be measured at the time of its manufacture, for example. When basic magnesium carbonate is obtained by reaction crystallization by the carbonation method, it can be adjusted by controlling the initial concentration of magnesium hydroxide used as a raw material and the reaction temperature.
