Description

本発明は付加反応硬化型のオルガノポリシロキサン組成物に関する。   The present invention relates to an addition reaction curable organopolysiloxane composition.

従来、付加反応硬化型のオルガノポリシロキサン組成物に用いられる反応抑制剤として各種のものが提案されているが、中でもアセチレンアルコール系は保存安定性が最も優れている抑制剤として知られ、また反応抑制効果も優れているため、広く使用されている。しかし、この種の抑制剤を含むオルガノポリシロキサン組成物は表面から硬化が進むため、厚手の硬化物を得ようとすると、硬化物表面に細かいしわや凹凸を生じるという欠点がある。このため、上記組成物は例えば半導体デバイスのコーティング剤のようにコーティングした組成物に内部歪がなく、且つ硬化物の表面平滑性を必要とする用途(特にイメージセンサー、LED、レーザーダイオード、フォトダイオード等の光学デバイス用)には適さない場合がある。   Conventionally, various types of reaction inhibitors used in addition reaction curable organopolysiloxane compositions have been proposed. Among them, acetylene alcohols are known as inhibitors having the best storage stability, and are also reactive. Widely used because of its excellent suppression effect. However, since the organopolysiloxane composition containing this type of inhibitor is cured from the surface, there is a drawback that fine wrinkles and irregularities are generated on the surface of the cured product when a thick cured product is obtained. For this reason, the composition described above is used in applications in which the coating composition such as a coating agent for semiconductor devices has no internal distortion and requires the surface smoothness of a cured product (particularly image sensors, LEDs, laser diodes, photodiodes). Etc. for optical devices).

その対策として、酸素原子を介してケイ素原子に結合した−C≡C−結合を有するアルキニルオキシ基を含有するオルガノポリシロキサンを用いた組成物が提案されている(特許文献1)。この組成物は硬化物の表面平滑性に優れるが、前記アセチレンアルコール系反応抑制剤を用いた組成物に比べて保存安定性に劣り、長期保存に問題があった。   As a countermeasure, a composition using an organopolysiloxane containing an alkynyloxy group having a —C≡C— bond bonded to a silicon atom via an oxygen atom has been proposed (Patent Document 1). Although this composition is excellent in the surface smoothness of the cured product, it is inferior in storage stability and has a problem in long-term storage as compared with the composition using the acetylene alcohol-based reaction inhibitor.

特公昭54−3774号公報Japanese Patent Publication No.54-3774

従って、本発明の課題は反応抑制効果に優れるアセチレンアルコール系反応抑制剤に硬化物の表面平滑性に優れるアルキニルオキシ基含有オルガノポリシロキサンを組合せることにより、組成物の保存安定性及び硬化物の表面平滑性に優れた付加反応硬化型のオルガノポリシロキサン組成物を提供することである。   Therefore, the object of the present invention is to combine the acetylene alcohol-based reaction inhibitor having an excellent reaction suppressing effect with the alkynyloxy group-containing organopolysiloxane having an excellent surface smoothness of the cured product, thereby to preserve the storage stability of the composition and the cured product. An addition reaction curable organopolysiloxane composition having excellent surface smoothness is provided.

(E) Alkynyloxy group-containing organopolysiloxane The alkynyloxy group-containing organopolysiloxane used in the present invention is a monovalent hydrocarbon group having a —C≡C— bond bonded to a silicon atom via an oxygen atom (ie, , An alkynyloxy group bonded to a silicon atom) in one molecule and a vapor pressure of 2 mmHg or less at 120 ° C. The monovalent hydrocarbon group (alkynyloxy group) having a —C≡C— bond may be bonded to any silicon atom in the molecular chain terminal or in the molecular chain. It is preferably bonded to a silicon atom. In the alkynyloxy group, the —C≡C— bond is preferably located at the terminal (that is, has a —C≡CH structure). In addition, as the monovalent substituent bonded to the silicon atom other than the alkynyloxy group in the organopolysiloxane of component (E), the same unsubstituted or substituted monovalent hydrocarbon group as R 1 described above can be exemplified. . Further, this organopolysiloxane may contain one or more SiH groups in the molecule. Furthermore, the organopolysiloxane of component (E) may be structurally linear, branched, cyclic, or three-dimensional network, and the number of silicon atoms in the molecule is usually 4 to 4. It may be about 200, preferably about 8 to 120.

このような成分(E)としては、具体的には下記式で示されるものが挙げられる。   Specific examples of such component (E) include those represented by the following formula.

この成分(E)は上記成分(A)及び(B)との相溶性に優れているものが好ましい。成分(E)が相溶性に劣っていると、その硬化に長時間を要する上、均一に硬化せず、また硬化物に濁りを生じて透明性を阻害したり、部分的に硬化不良を起こすという不利がある。   This component (E) is preferably excellent in compatibility with the components (A) and (B). If the component (E) is poorly compatible, it will take a long time to cure, and it will not cure uniformly, and the cured product will become turbid, hindering transparency or causing partial curing failure. There is a disadvantage.

成分(E)のアルキニルオキシ基含有オルガノポリシロキサンは、例えば次のような方法で容易に製造することができる。即ち、(CH3)(H)Si0単位、(CH32(H)Si01/2単位、及びHSiO3/2単位の少なくとも1種を含有するオルガノハイドロジェンポリシロキサンにアセチレン結合を有するアルコール類をアルカリアルコキシド又はアミン類の存在下に適当な溶剤中で脱水素反応によって付加させた後、これを適当な酸類又はハロシラン類で中和し、次いで溶剤及び低沸点化合物を留去する。この場合のオルガノハイドロジェンポリシロキサンとアセチレン結合を有するアルコール類との配合割合は、アルコール類中の水酸基がオルガノハイドロジェンポリシロキサン中のケイ素原子に結合した水素原子1個当たり1個以上となるような割合である。また、上記溶剤及び低沸点化合物(特に沸点250℃以下の化合物)を留去する際は、できるだけ十分に留去することが望ましく、もしこの留去が不十分である場合には得られる化合物にしわができ易いという不利が生じる。
ここで使用できるアセチレン結合を有するアルコール類としては、下記のような化合物が例示される。
The alkynyloxy group-containing organopolysiloxane of component (E) can be easily produced, for example, by the following method. That is, an alcohol having an acetylene bond in an organohydrogenpolysiloxane containing at least one of (CH 3 ) (H) Si 0 unit, (CH 3 ) 2 (H) Si 0 1/2 unit, and HSiO 3/2 unit Are added by dehydrogenation in a suitable solvent in the presence of alkali alkoxides or amines, then neutralized with suitable acids or halosilanes, and then the solvent and low-boiling compounds are distilled off. In this case, the blending ratio of the organohydrogenpolysiloxane and the alcohol having an acetylene bond is such that the hydroxyl group in the alcohol is one or more per one hydrogen atom bonded to the silicon atom in the organohydrogenpolysiloxane. The ratio is Further, when distilling off the solvent and low boiling point compounds (especially compounds having a boiling point of 250 ° C. or less), it is desirable to distill off as much as possible. If this distilling is insufficient, the resulting compound is obtained. There is a disadvantage that it is easy to do.
Examples of alcohols having an acetylene bond that can be used here include the following compounds.

Figure 2005146288
以上のような方法で得られるアルキニルオキシ基含有オルガノポリシロキサンは、1種単独で又は2種以上組み合わせて使用することができる。
Figure 2005146288
The alkynyloxy group-containing organopolysiloxane obtained by the above method can be used alone or in combination of two or more.

成分(E)のアルキニルオキシ基含有オルガノポリシロキサンの使用量は、重量で成分(D)の0.5〜100倍、好ましくは1〜50倍程度でよい。   The amount of the component (E) alkynyloxy group-containing organopolysiloxane used may be about 0.5 to 100 times, preferably about 1 to 50 times that of the component (D) by weight.

その他の添加物

However, when such a vinyl group-containing organopolysiloxane resin is added, as defined in Component (B), the amount used is silicon relative to one vinyl group bonded to silicon atoms in the entire composition. The amount needs to be 0.5 to 4 hydrogen atoms bonded to the atoms.
