【請求項３】
ポリイソシアネ−トがポリメチレンポリフェニレンポリイソシアネ−ト、４，４’−ジフェニルメタンジイソシアネ−ト、粗製ポリメチレンポリフェニレンポリイソシアネ−ト、あるいはポリメチレンポリフェニレンポリイソシアネ−トの変性ポリイソシアネ−トである特許請求項１記載の植物固定支持用連続気泡ポリイソシアヌレ−トフォ−ム。

The polyisocyanate is polymethylene polyphenylene polyisocyanate, 4,4'-diphenylmethane diisocyanate, crude polymethylene polyphenylene polyisocyanate, or a modified polyisocyanate of polymethylene polyphenylene polyisocyanate. The open-celled polyisocyanurate foam for supporting plant fixation according to claim 1.
【００１３】
【発明が解決しようとする課題】
以上の様に従来の植物固定支持用ポリウレタンフォ−ムは連泡化率が低く、柔軟性を有していることから親水性は満足するが水吸収量が低く、しかもさし込み時にフォ−ムが伸びてしまい、いわゆる均一圧力に対する均一挫屈ではなく従って柔らかい草花をさすことが困難であった。またイソシアネ−ト インデックスを上げて挿し込み性を向上させると独立気泡が増し、更に吸水性が低下するという解決困難なものであった。
[0013]
[Problems to be solved by the invention]
As described above, the conventional polyurethane foam for fixing and supporting plants has a low open cell ratio and is flexible, and therefore satisfies hydrophilicity, but has a low water absorption, and has a low foaming property when inserted. And it was not a uniform buckling to a so-called uniform pressure, and it was therefore difficult to point to a soft flower. In addition, when the isocyanate index is increased to improve the insertability, the number of closed cells increases, and the water absorption decreases, which is difficult to solve.
本発明に使用するシリコン系整泡剤としてはポリシロキサン−ポリオキシアルキレン共重合体であり、そのポリオキシアルキレン末端ＯＨ基が他の活性水素を有さない化合物でキャップされている構造をなす必要がある。好ましい具体的例としては１〜４のアルコキシ基、アセトキシ基、あるいは脂肪族アシロキシ基で単独あるいは併用でキャップされた構造であり、更に好ましくは１〜４のアルコキシ基、並びにアセトキシ基である。またオキシエチレン鎖は全オキシアルキレン鎖の３０重量％以上含有するのが良い。本ポリシロキサン−ポリオキシアルキレン共重合体の代表的化学構造の例としては下記の通りである。 The silicone-based foam stabilizer used in the present invention is a polysiloxane-polyoxyalkylene copolymer, which has a structure in which the polyoxyalkylene terminal OH group is capped with another compound having no active hydrogen. There is. Preferred specific examples have a structure capped with one to four alkoxy groups, acetoxy groups, or aliphatic acyloxy groups alone or in combination, and more preferably, one to four alkoxy groups and acetoxy groups. The oxyethylene chain preferably contains 30% by weight or more of the entire oxyalkylene chain. Examples of typical chemical structures of the present polysiloxane-polyoxyalkylene copolymer are as follows.
比較例１
グリセリンにエチレンオキサイドとプロピレンオキサイドを７８／２２の割合でランダムに付加させた分子量約３４００のポリエーテルポリオ−ル（Ｐｏｌｙｏｌ−１）を使用し実施例２と同様にポリイソシアヌレ−トフォ−ムを製造した。但し、シリコン系整泡剤については、ポリオキシアルキレン末端がＯＨ基でキヤップしたシリコン系整泡剤（シリコン系整泡剤−５）を使用した。本フォ−ムは実施例２同様に活性水素を有さないポリオキシアルキレン誘導体並びにアニオン系界面活性剤を使用しているが吸水時間テストでは４８６０秒となり、水を全く吸収しなかった。浸水時間テストでも全く沈まなかった。物性を表２に示す。
Comparative Example 1
Using a polyether polyol (Polyol-1) having a molecular weight of about 3400 obtained by randomly adding ethylene oxide and propylene oxide at a ratio of 78/22 to glycerin, a polyisocyanurate form was prepared in the same manner as in Example 2. Manufactured. However, as the silicon-based foam stabilizer, a silicone-based foam stabilizer (silicon-based foam stabilizer-5) in which the polyoxyalkylene terminal was capped with an OH group was used. This form used a polyoxyalkylene derivative having no active hydrogen and an anionic surfactant similarly to Example 2, but the water absorption time test was 4860 seconds, and no water was absorbed. It did not sink at all in the soaking time test. Table 2 shows the physical properties.
比較例２
グリセリンにエチレンオキサイドとプロピレンオキサイドとを７８／２２の割合でランダムに付加させた分子量約３４００のポリエ−テルポリオ−ル（Ｐｏｌｙｏｌ−１）並びにグリセリンにプロピレンオキサイドを付加させた分子量３０００のポリエ−テルポリオ−ル（Ｐｏｌｙｏｌ−２）、粗製ポリメチレンポリフェニレンポリイソシアネ−ト（ｐａｐｉ−１３５）、活性水素を有さないポリオキシアルキレン末端をメトキシ基でキヤップしたシリコン系整泡剤−１を用い、活性水素を有さないポリオキシアルキレン誘導体を用いずポリイソシアヌレ−トを発泡したが消泡して正常のフォ−ムとはならなかったので物性の測定はできなかった。
Comparative Example 2
Polyetherpolyol (Polyol-1) having a molecular weight of about 3400 obtained by randomly adding ethylene oxide and propylene oxide to glycerin at a ratio of 78/22 and polyetherpolyol having a molecular weight of 3000 obtained by adding propylene oxide to glycerin. (Polyol-2) , crude polymethylene polyphenylene polyisocyanate (papi-135), and a silicon-based foam stabilizer-1 having no active hydrogen and having a polyoxyalkylene terminal capped with a methoxy group. The polyisocyanurate was foamed without using the polyoxyalkylene derivative having no but the foam was defoamed and did not become a normal foam, so that physical properties could not be measured.
