Definitions
- the present invention comprises (A) a polyether-polysiloxane block copolymer having a specific structure, and (B) a specific monool organic compound that is liquid at 5 ° C.
- the present invention relates to a novel polyether-polysiloxane block copolymer composition which does not contain more than mass and a method for producing the same.
- the present invention also relates to a surfactant, a foam stabilizer (including functions as a bubble control agent and a bubble stabilizer, the same applies hereinafter), a cosmetic raw material and a cosmetic containing the composition.
- this invention relates to the polyurethane foam formation composition containing the said composition, and the polyurethane foam obtained from it.
- Patent Document 1 The linear organopolysiloxane-polyether block copolymer obtained by hydrosilylation reaction between (1) both-end SiH group-containing organopolysiloxane and (2) both-end methallyl group-containing polyether is (AB) n-type polyether It is known as a modified silicone (Patent Document 1). Furthermore, Patent Document 2 reports a method for producing a polyurethane foam using a non-hydrolyzable linear organopolysiloxane-polyether block copolymer having a high degree of polymerization as a foam stabilizer.
- composition containing the block copolymer was a toluene solution obtained as a result of carrying out the hydrosilylation reaction in a toluene solvent.
- Toluene is removed from the product system by stripping treatment under heating or reduced pressure conditions because of its high hazard risk such as its toxicity and flammability.
- a xylene solution containing the block copolymer is known and commercialized, but there is also a problem that it contains a flammable and harmful organic solvent.
- Patent Documents 3 to 8 Some reports have been made on the application of the (AB) n-type polyether-modified silicone (Patent Documents 3 to 8).
- Patent Documents 3 and 4 relate to cosmetics containing the (AB) n-type polyether-modified silicone. After the synthesis of the modified silicone in toluene as in Patent Documents 1 and 2, the toluene was removed. Examples are disclosed which are incorporated into several cosmetic formulations. In the text, it is stated that the copolymer is used alone or dissolved in water or various organic solvents. Similarly, in Patent Document 5 and Patent Document 6, the (AB) n-type polyether-modified silicone synthesized in an organic solvent such as toluene is used as a foam stabilizer (bubble stabilizer) for urethane foam.
- an organic solvent such as toluene
- Patent Document 6 discloses an example in which after the synthesis of the copolymer in toluene, polypropylene glycol as a diluent was added, and toluene was further removed by a stripping operation. It is mentioned that polyols used in urethane foam formulations can also be used as the agent. Furthermore, as a comparative example, a commercial foam stabilizer using a long-chain alkylbenzene as a reaction solvent is taken up.
- Patent Document 6 after hydrosilylation in toluene, after addition of polypropylene glycol or its derivative as a diluent and solvent exchange in which toluene is removed by vacuum stripping, the above (AB) Since the n-type polyether-modified silicone is excellent in bubble stability, the bubbles involved by stirring are fine and very stable, and bubble breakage is suppressed. The upper space of the reactor is immediately filled with bubbles, The decompression operation has to proceed very slowly. That is, this manufacturing method is disadvantageous in industrial mass production.
- Patent Document 6 discloses that a foam stabilizer is synthesized in a long-chain alkylbenzene and used as it is, but such a non-reactive solvent remains in the urethane foam and is finally used. There is a problem of migration from the product.
- references 1 to 6 not only describe or suggest the use of a specific monool organic compound as a solvent for the (AB) n-type polyether-modified silicone, and the benefits thereof.
- a specific monool organic compound as a solvent for the (AB) n-type polyether-modified silicone, and the benefits thereof.
- Patent Document 7 particularly relates to a hair cosmetic containing a specific structure having a high molecular weight among the (AB) n-type polyether-modified silicone.
- Patent Document 8 discloses a fiber thread-like material comprising a specific structure having a high molecular weight among the (AB) n-type polyether-modified silicone and a base oil composed of at least one selected from diorganopolysiloxane and mineral oil. It relates to a straight oil for processing.
- Patent Document 9 discloses that (AB) n-type polyether-modified silicone or a similar structure, particularly a high molecular weight copolymer can be produced stably without causing thickening or gelation.
- the technique for doing is disclosed.
- the copolymer is synthesized in fluid isoparaffin (hydrogenated polyisobutene), and then low-boiling substances such as unreacted substances are distilled off by stripping (under heating and decompression conditions).
- several organic solvents and dimethylpolysiloxane are exemplified as solvents that can be used in the hydrosilylation reaction step for synthesizing the copolymer.
- compositions disclosed in Patent Documents 1 to 9 are compositions that cannot be used as surfactants or foam stabilizers for urethane foam, or are obtained by synthesis in a highly toxic organic solvent such as toluene.
- a highly toxic organic solvent such as toluene.
- propylene glycol or the like there is inevitably disadvantageous in industrial production, or there is a problem in the performance as a foam stabilizer, leaving room for improvement in performance and production cost. It was. Therefore, these compositions are not fully satisfactory in terms of their usefulness as surfactants and foam stabilizers, and have a problem that their widespread use is hindered due to performance and cost problems. It was.
- the n-type polyether-modified silicone can be designed with an average molecular weight of the copolymer, and the interface can be increased by introducing EO% and size of the polyether part, and introducing a hydroxyl group or a hydrophobic group into the terminal part of the copolymer.
- the ability to control activity and affinity for urethane foam systems can be controlled, so all foam foam formulations other than high resilience foam (High Resilience ⁇ Foam) that require low molecular weight foam stabilizers are used for cell control or cell stability. It is considered that an excellent effect can be exerted as a surfactant for use. In particular, it is extremely useful in controlling the open cell rate required in recent years.
- the present invention has been made to solve the above-mentioned problems, and in the fields of high-density microcellular foam by mechanical foaming, other hard foams and flexible foams, control of the open cell rate is not limited to simple bubble stabilizers.

- compositions other than Comparative Examples 1-7 and 1-8 that could not be synthesized at all contained the following linear organopolysiloxane-polyether block copolymer as component (A).
- polyglycols conventionally used as a diluent for (AB) n-type polyether-polysiloxane block copolymer cannot be used as a synthetic solvent for the copolymer. This is because the hydrosilylation reaction does not proceed at all. This is because polyglycols have a large molecular weight, so that both ends SiH group-containing organopolysiloxane and both ends methallyl group-containing polyether are compatibilized, and the viscosity of the reaction system is lowered to allow both to contact. The point which lacks the effect which increases the opportunity to mix is mentioned.
- glycol ethers having a low molecular weight and a small number of repeating units are generally sold by distillation and purification, there is no problem in inhibiting hydrosilylation due to impurities, and the molecular structure also includes terminal SiH groups. It is thought that it was useful as a reaction solvent and diluent for the (AB) n-type polyether-polysiloxane block copolymer because of its high ability to compatibilize the organopolysiloxane containing both ends and methallyl group-containing polyether. .
- the glycol ether which is the component (B) of the present invention and has a low molecular weight and a small number of repeating units Cases where the class is said to be useful have not been reported to the extent investigated by the inventors.
- glycol ethers having a low molecular weight and a small number of repeating units are often treated collectively as so-called “glycol ethers” because of their relatively similar structures and properties.
- glycol ethers As a result of a detailed investigation as a reaction solvent and residual diluent for the (AB) n-type polyether-polysiloxane block copolymer, it was found that the EO derivative glycol ether and the PO derivative glycol ether were useful. It turns out that there is a big difference.
- Example 2-5 A liquid higher alcohol compound having a branched alkyl group having 12 to 24 carbon atoms and benzyl alcohol were taken up and tested. As a result, it was surprisingly found that only the former case (Example 2-5) has an effect of achieving the object.
- Table 4 below shows the results of GPC measurement of the polyether-polysiloxane block copolymer composition according to the present invention (Example 2-5) thus obtained under the same conditions as described above.
- Example 1-1 was used as the polyether-polysiloxane block copolymer composition of the present invention, and (AB) n-type polyether according to the prior art (Patent Document 6: JP-A-08-156143).
- Comparative Example 2-1 was taken up as a polysiloxane block copolymer, and a miscibility test with water of both was performed. The test method is shown below.
- the polyether-polysiloxane block copolymer composition of the present invention has a hydrogel formation problem due to contact with water which the conventional (AB) n-type polyether-polysiloxane block copolymer has. It was proved that it completely solved the problem. Also, it became clear that the formation of the composition by the combined use of the polyether-polysiloxane block copolymer (A) and the component (B) according to the present invention was the key to solving this problem. It was. Therefore, the polyether-polysiloxane block copolymer composition of the present invention can be widely used for urethane foam formulations (for example, flexible foams) whose open cell rate is desired to be adjusted or made open cell.
- urethane foam formulations for example, flexible foams
- the present inventors carried out a foaming test by blending several picked-up samples into a rigid urethane foam formulation based on the knowledge of the type of polyurethane foam and the tendency of the molecular weight of the polyether-modified silicone compatible therewith.
- the polyether-polysiloxane block copolymer composition (sample) according to the present invention one having a relatively small molecular weight is selected, and the conventional technology (Patent Document 6: Japanese Patent Laid-Open No. 08-156143) (AB) Comparison was made with Comparative Example 2-1 which is an n-type polyether-polysiloxane block copolymer composition.
- the tested rigid foam formulations are shown below.
- Polyol, water, catalyst and surfactant were accurately weighed in a 200 ml polycup and stirred at 3500 rpm for 15 seconds with a disc blade type disper mixer.
- the isocyanate was then added to the premixed premix solution described above and mixed for 7 seconds at 3500 rpm using the same blade.
- the uniformly mixed urethane foam-forming composition was poured into a 1 L paper cup over 8 seconds to allow free foaming. It was allowed to stand for 40 to 60 minutes in a constant temperature room. After 2 hours, each foam was cut in half from the top, and the foam height and the cell structure of the cut surface were observed and recorded.
- the polyether-polysiloxane block copolymer composition according to the present invention has an excellent effect as a cell stabilizer or a surfactant for rigid polyurethane foam.
- Table 8 shows foam formulation examples of the microcellular polyurethane foam-forming composition, and the production process is briefly shown.
- Example of manufacturing process 1) The premix solution and isocyanate (the amount that gives an isocyanate index of 107) are stirred and mixed by a dynamic mixer for 1 minute while feeding nitrogen gas, and poured into a mold as it is. 2) After primary curing at 160 ° C. for 30 minutes, secondary curing is performed at 110 ° C. for 4 hours. 3) Thereafter, a metal shaft is press-fitted and bonded to this, and the end is cut and the surface is polished to obtain a microcellular polyurethane foam.
- the polyurethane foam according to the present invention does not contain a residual substance such as non-reactive dodecylbenzene in the foam stabilizer (cell stabilizer), the obtained microcellular foam has a problem of migration (exudation). It is hard to wake up. Since the diluent (B) component contained in the foam stabilizer of the present invention has appropriate volatility and reactivity in the urethane foam formulation, for example, in the formulation examples 1 and 2, an increase in cell opening action associated with the volatilization effect (Formation of a highly breathable and flexible foam) is expected.

さらに、本発明のポリエーテル-ポリシロキサンブロック共重合体の用途に応じ、粗製品の精製や低臭化が求められる場合には、水素添加、酸性物質との接触および生成するアルデヒド類を除去する等の公知の精製方法を用いてもよい。これらの方法は、例えば、特開2007-186557号公報の段落0031等で提案された精製方法1および精製方法2や、特開2000-327785号公報等で提案された匂いの低減方法、本件出願人が特開2011-116902号公報で提案した酸性無機塩を用いた処理方法等から特に制限なく選択することができる。特に、これらの精製方法を行うことで、ポリウレタン発泡体に配合された場合であっても経時で発生する有害なアルデヒド類の量が極めて少なくなり、建築用材料、自動車工業(例えば、自動車内装材料)、ベッド、ソファー等の家具類、寝具、衣類等に適用されるポリウレタン発泡体の整泡剤として有用であるほか、化粧料原料としての有用性がさらに改善される利点がある。
本発明のポリエーテル-ポリシロキサンブロック共重合体組成物は、前記一般式(2)で表される両末端SiH基含有オルガノポリシロキサンと前記一般式(3)で表される分子鎖両末端にメタリル基(RVi)を有するポリエーテルとのヒドロシリル化を実質的に無溶媒下で開始する工程、および、反応終了後あるいは反応中に前記成分(B)であるモノオール有機化合物を加えて希釈ないし反応促進させる工程を少なくとも含む製造法により、好適に製造することができる。無溶媒下で反応を完了させた後に成分(B)を加えて希釈する事もできるし、無溶媒下の反応が途中の段階から成分(B)を加えて反応を完了させる事もできる。本製造方法は、原則として、ストリピング工程を必要としない。また、本発明のポリエーテル-ポリシロキサンブロック共重合体は、整泡剤としての性能に優れるので泡の安定化が起き易い。このため、トルエンのような溶媒存在下で反応を行うと、トルエン等の除去のために減圧除去(ストリピング)を行うと、発生した泡が破泡せず、反応釜上部まで覆い尽くしてしまうために工業的生産上のサイクルタイムが増大し、不利になる場合があるが、無溶媒下で反応を開始することで、かかる工業生産上の問題を解消できる場合がある。なお、無溶媒下で反応を開始し、ある程度反応が進んでから前記成分(B)であるモノオール有機化合物を添加することで、共重合に伴う粘度上昇を抑制し、攪拌効率および反応性を改善することもできる。なお、無溶媒下におけるポリエーテル-ポリシロキサンブロック共重合体の合成方法として、特開平01-101333号公報に記載の方法等を用いてもよい。
本発明のポリエーテル-ポリシロキサンブロック共重合体組成物は、前記一般式(2)で表される両末端SiH基含有オルガノポリシロキサンと前記一般式(3)で表される分子鎖両末端にメタリル基を有するポリエーテルとのヒドロシリル化を前記成分(B)であるモノオール有機化合物の存在下で開始ないし進行させる工程を少なくとも含む製造法により、好適に製造することができる。本製造方法では、成分(B)以外の溶媒又は希釈剤が同時に存在している事もできるが、そうでない場合にはストリピング工程を必要としない。一方成分(B)以外の溶媒又は希釈剤を同時に存在させた場合は、反応終了後にそれらを除く必要がある場合に限りストリピング工程が必要となる。当該方法は、上記の製造工程における発泡と工業的生産効率の悪化の問題が殆どなく、成分(B)以外の溶媒を用いない場合には、溶媒交換等の追加の工程を行う必要がなく、反応開始~得られる組成物の粘度が抑制されるために攪拌効率および反応効率に優れ、得られるポリエーテル-ポリシロキサンブロック共重合体組成物の界面活性剤または整泡剤としての品質及び機能を著しく改善しうるものである。
本発明のポリエーテル-ポリシロキサンブロック共重合体組成物は、前記一般式(2)で表される両末端SiH基含有オルガノポリシロキサンと前記一般式(3)で表される分子鎖両末端にメタリル基を有するポリエーテルとのヒドロシリル化を前記成分(B)と異なる揮発性有機溶媒(B´)の存在下において開始ないし進行させる工程;および当該成分(B)と異なる揮発性有機溶媒(B´)を、前記成分(B)であるモノオール有機化合物と溶媒交換を行う工程を少なくとも含む製造法により、好適に製造することができる。

本発明のポリエーテル-ポリシロキサンブロック共重合体組成物は、発泡性樹脂、特に、ポリウレタン発泡体の製造時に、気泡コントロール或いは気泡安定用の界面活性剤、特に、整泡剤として好適に使用できる。特に本発明にかかる組成物は、単なる気泡安定剤に留まらずオープンセル率のコントロールが可能であり、プレミックス液の均質性や安定性に優れ、またフォーム形成用エマルション組成物中での各種成分との相溶性にも優れ、しかもマイクロセルラー用途での気泡保持性にも優れるという利点を有する。

前述の実施例2-4で得られたポリエーテル-ポリシロキサンブロック共重合体組成物40gと、HO(C3H6O)7-Hで表されるポリプロピレングリコール(PPG-7)40gとを200mlガラス瓶に仕込み、室温下にホモディスパーミキサーにて1600rpm×5分間の混合を行なった。これにより、共重合体:BDPG:{PPG-7}=1:3:4の存在比である液状のポリエーテル-ポリシロキサンブロック共重合体組成物を得た。
前述の実施例3-2で得られたポリエーテル-ポリシロキサンブロック共重合体組成物40gと、ドデシルベンゼン(DB)35gとを200mlガラス瓶に仕込み、室温下にホモディスパーミキサーにて1600rpm×5分間の混合を行なった。これにより、共重合体:BPG:DB=3:1:3.5の存在比である液状のポリエーテル-ポリシロキサンブロック共重合体組成物を得た。
1L反応器に、平均組成式 MHD20MH で表されるメチルハイドロジェンポリシロキサン75.25g、平均組成式CH2=C(CH3)CH2-O(C2H4O)33(C3H6O)25-CH2-C(CH3)=CH2 で表されるビスメタリルポリエーテル174.75g、ヘキシレングリコール(HG,別名2-メチルペンタン-2,4-ジオール)250g、天然ビタミンEを0.25g仕込み、窒素流通下で攪拌しながら80~90℃まで加温した。白金-2,4,6,8-テトラメチル-2,4,6,8-テトラビニルテトラシロキサン錯体のIPA溶液(Pt濃度0.45wt%)を0.56g添加し、1.5~2時間反応を行なった。次いで反応液を1g採取し、アルカリ分解ガス発生法(残存したSi-H基をKOHのエタノール/水溶液によって分解し、発生した水素ガスの体積から反応率を計算する)により反応率を確認したところ、反応が遅く完結していないことが分かった。そこで、反応液を115~120℃まで加熱して2~3時間反応を継続した結果、反応が完結した。これにより、平均組成式
で表される構成単位を少なくとも含有する、直鎖状オルガノポリシロキサン-ポリエーテルブロックコポリマーとHGとを50:50の比率で含む、液状のポリエーテル-ポリシロキサンブロック共重合体組成物を得た。なお、平均組成式を簡易に表記したが、原料のC=C基とSi-H基のモル比はおよそ7:6であるため、共重合体の両末端はポリエーテルで封鎖された形となっている。また、反応中に一部のSi-H基はIPA或いはHGの水酸基と脱水素縮合反応を起こし得るので、共重合体末端の一部はSiO-iPr或いはSiO-R1(R1はHGの残基)の構造を含むと考えられる。なお、ここでポリエーテル部分は、エチレンオキサイドとプロピレンオキサイドのランダム付加体である。
HGを別の以下の低分子量ジオール化合物に変更したほかは、比較例1-1と同様にして、実験を行った。
比較例1-2:プロピレングリコール(PG)
比較例1-3:ジプロピレングリコール(DPG)
比較例1-4:トリプロピレングリコール(TPG)
比較例1-5:1,2-ブチレングリコール(1,2-BG)
比較例1-6:1,3-ブチレングリコール(1,3-BG)
上記の実験において、直鎖状オルガノポリシロキサン-ポリエーテルブロックコポリマーの合成反応における反応性などの挙動は、比較例1-1と同様であった。
1L反応器に、平均組成式 MHD20MH で表されるメチルハイドロジェンポリシロキサン75.25g、平均組成式CH2=C(CH3)CH2-O(C2H4O)33(C3H6O)25-CH2-C(CH3)=CH2 で表されるビスメタリルポリエーテル174.75g、HO(C3H6O)7-Hで表されるポリプロピレングリコール(PPG-7)250g、天然ビタミンEを0.25g仕込み、窒素流通下で攪拌しながら80~90℃まで加温した。白金-2,4,6,8-テトラメチル-2,4,6,8-テトラビニルテトラシロキサン錯体のIPA溶液(Pt濃度0.45wt%)を0.56g添加し、1.5~2時間反応を行なった。次いで反応液を1g採取し、アルカリ分解ガス発生法により反応率を確認したところ、全く反応が進行していないことが分かった。そこで、更に2倍量の触媒を追加して反応液を115~120℃まで加熱して2~3時間反応を継続し、同様に反応率を確認したが、全く反応が進行していなかった。加熱攪拌を停止して一夜間静置したのちフラスコ内容物を確認すると、シロキサン層とポリエーテル層の二層に分離しており、この条件下では共重合体の合成が不可能である事が分かった。
前述の比較例1-7に倣って、但しPPG-7をn-BuO(C3H6O)13-Hで表されるポリプロピレングリコールモノブチルエーテルに変更して実験を行った。しかし、同様に全くヒドロシリル化反応が進行せず、シロキサン層とポリエーテル層の二層分離が確認され、共重合体の合成が不可能であることが分かった。
1L反応器に、平均組成式 MHD20MH で表されるメチルハイドロジェンポリシロキサン75.25g、平均組成式CH2=C(CH3)CH2-O(C2H4O)33(C3H6O)25-CH2-C(CH3)=CH2 で表されるビスメタリルポリエーテル174.75g、ジエチレンングリコールモノブチルエーテル(BDEG)250g、天然ビタミンEを0.25g仕込み、窒素流通下で攪拌しながら80~90℃まで加温した。白金-2,4,6,8-テトラメチル-2,4,6,8-テトラビニルテトラシロキサン錯体のIPA溶液(Pt濃度0.45wt%)を0.56g添加し、3時間反応を行なった。次いで反応液を1g採取しアルカリ分解ガス発生法により確認したところ、反応は完結していた。これにより、比較例1と同様に、直鎖状オルガノポリシロキサン-ポリエーテルブロックコポリマーとBDEGとを50:50の比率で含む、液状のポリエーテル-ポリシロキサンブロック共重合体組成物を得ることができた。
1L反応器に、平均組成式 MHD20MH で表されるメチルハイドロジェンポリシロキサン75.25g、平均組成式CH2=C(CH3)CH2-O(C2H4O)33(C3H6O)25-CH2-C(CH3)=CH2 で表されるビスメタリルポリエーテル174.75g、トルエン375g、天然ビタミンEを0.25g仕込み、窒素流通下で攪拌しながら70~80℃まで加温した。塩化白金酸の10%IPA溶液(Pt濃度3.8wt%)を0.05g添加し、2時間反応を行なった。次いで反応液を1g採取し、アルカリ分解ガス発生法により確認したところ反応は完結していた。反応系を徐々に減圧しながら更に125℃まで加熱して、泡立ちによる突沸に注意しつつトルエンを少しずつ留去した。約3/4のトルエンが除かれた段階で復圧し、125gのn-BuO(C3H6O)13-Hで表されるポリプロピレングリコールモノブチルエーテル{BPPG-13}を反応系に加えたのち、再度減圧して残存するトルエンを注意深く留去した。復圧して125gのBPPG-13を添加し、混合均質化した。これにより、平均組成式
で表される構成単位を少なくとも含有する直鎖状オルガノポリシロキサン-ポリエーテルブロックコポリマーとBPPG-13とを50:50の比率で含む、液状のポリエーテル-ポリシロキサンブロック共重合体組成物を得た。なお、平均組成式を簡易に表記したが、原料のC=C基とSi-H基のモル比はおよそ7:6であるため、共重合体の両末端はポリエーテルで封鎖された形となっている。また、反応中に一部のSi-H基はIPAの水酸基と脱水素縮合反応を起こし得るので、共重合体末端の一部はSiO-iPrの構造を含むと考えられる。なお、ここでポリエーテル部分は、エチレンオキサイドとプロピレンオキサイドのランダム付加体である。
1L反応器に、平均組成式 MHD20MH で表されるメチルハイドロジェンポリシロキサン84.25g、平均組成式CH2=C(CH3)CH2-O(C2H4O)33(C3H6O)25-CH2-C(CH3)=CH2 で表されるビスメタリルポリエーテル165.75g、ベンジルアルコール(BZL)250g、天然ビタミンEを0.25g仕込み、窒素流通下で攪拌しながら80~90℃まで加温した。白金-2,4,6,8-テトラメチル-2,4,6,8-テトラビニルテトラシロキサン錯体のIPA溶液(Pt濃度0.45wt%)を0.56g添加して1.5時間反応を行なったが、外観は強く白濁し反応が進行している様子は認められなかった。そこで、反応温度を100℃として更に2時間熟成を行ったが、反応率にも外観にも変化は無かった。触媒を同量追加して、反応温度120-125℃までアップして更に7時間の熟成を行なったにもかかわらず反応が完結しなかったため、実験を中止した。
1L反応器に、平均組成式 MHD20MH で表されるメチルハイドロジェンポリシロキサン76.75g、平均組成式CH2=C(CH3)CH2-O(C2H4O)52(C3H6O)10-CH2-C(CH3)=CH2 で表されるビスメタリルポリエーテル173.25g、ヘキシレングリコール(HG,別名2-メチルペンタン-2,4-ジオール)250g、天然ビタミンEを0.25g仕込み、窒素流通下で攪拌しながら85~110℃まで加温した。白金-2,4,6,8-テトラメチル-2,4,6,8-テトラビニルテトラシロキサン錯体のIPA溶液(Pt濃度0.45wt%)を0.56g添加し、2時間反応を行なった。次いで反応液を1g採取し、アルカリ分解ガス発生法により反応率を確認したところ、反応が遅く完結していないことが分かった。そこで、反応液を120℃まで加熱して7時間反応を継続した結果、反応が完結した。これにより、平均組成式
で表される構成単位を少なくとも含有する直鎖状オルガノポリシロキサン-ポリエーテルブロックコポリマーとHGとを50:50の比率で含む、液状のポリエーテル-ポリシロキサンブロック共重合体組成物を得た。なお、平均組成式を簡易に表記したが、原料のC=C基とSi-H基のモル比はおよそ7:6であるため、共重合体の両末端はポリエーテルで封鎖された形となっている。また、反応中に一部のSi-H基はIPA或いはHGの水酸基と脱水素縮合反応を起こし得るので、共重合体末端の一部はSiO-iPr或いはSiO-R1(R1はHGの残基)の構造を含むと考えられる。なお、ここでポリエーテル部分は、エチレンオキサイドとプロピレンオキサイドのランダム付加体である。
HGをジエチレングリコールモノブチルエーテル(BDEG)に置き換えた他は、比較例3-1と同様にして実験を行った。しかしながら、合成実験時の反応性は悪く、比較例3-1と同様であった。
上記実施例1-1~1-2、実施例2-1~2-5、実施例3-1~3-2、実施例4-1~4-2、実施例5-1~5-3、比較例1-1~1-9、比較例2-1~2-2、比較例3-1~3-2について、得られた各組成物の設計構造、内容、外観、25℃における動粘度(mm2/s)等を下表1および表2に示す。
「GPC測定条件」
溶離液: クロロホルム(試薬特級)
測定温度: 40℃
検出器: 屈折率計(プラス側にピーク検出)
流速: 1.0mL/min
校正: 標準ポリスチレンにより実施
サンプル溶液の注入量: 100μL (試料濃度1重量%)
合計量が、表6の16.7%であるようなスケールで、本発明のポリウレタンフォーム形成組成物の調製およびポリウレタンフォーム発泡体の形成を行った。なお、作業はおよそ25℃の恒温室内で行ない、原料も全て恒温に達している状態から使用した。
その後、イソシアナートを前述の予め混合されたプレミックス液へと添加し、同じブレードを用いて7秒間、3500rpmで混合した。
均一に混合されたウレタンフォーム形成組成物を、8秒間かけて1Lペーパーカップへと注ぎ、フリー発泡させた。
そのまま、恒温室内で40~60分間静置した。
2時間後、それぞれの発泡体を上部より半分に切断し、フォーム高さ及び切断面のセル構造を観察し、記録した。
1)プレミックス液と、イソシアナート(イソシアネートインデックスが107となる量)を、窒素ガスを送りながらダイナミックミキサーによって1分間攪拌混合し、そのまま型に注入する。
2)160℃で30分間一次硬化させた後、110℃で4時間二次硬化させる。
3)その後、このものに金属製のシャフトを圧入接着し、端部のカット、表面の研磨等を行ってマイクロセルラーポリウレタン発泡体を得る。
本発明に係るポリウレタンフォームは、整泡剤(気泡安定剤)中に、非反応性のドデシルベンゼンのような残留性物質を含まないため、得られたマイクロセルラーフォームはマイグレーション(滲み出し)の問題を起こし難い。本発明の気泡安定剤中に含まれる希釈剤:(B)成分は、ウレタンフォーム処方において適度な揮発性と反応性を有するため、例えば処方例1,2では揮発効果に伴うセルオープニング作用の増大(高通気性で柔軟な発泡体の形成)が期待される。また、(B)成分の使用量を減らして不揮発性のPPG-7を配合した気泡安定剤を用いた処方例4では、フォームの架橋密度アップに貢献するため低通気性で強度に優れた発泡体の形成が期待される。処方例3では、先の2つの中間的なバランスの取れた物性の発泡体の形成が期待される。
