Abstract
提供一种泡沫发泡剂共混物,它包括5-50%(摩尔)HCFC-22和95-5%(摩尔)的正戊烷、异戊烷和/或环戊烷,以及含这样的共混物的多元醇预混物和聚氨酯泡沫组合物。
Description
本发明涉及(a)一氯二氟甲烷(“HCFC-22”或“22”)与(b)正戊烷(n-C5)、异戊烷(i-C5)和/或环戊烷(c-C5)的泡沫发泡剂共混物,还涉及含这样的共混物的多元醇预混物和聚氨酯泡沫组合物。
迄今,为满足市场对能量、可燃性和成本的要求,主要的聚氨酯泡沫发泡剂一直是1,1-二氯-1-氟乙烷(“141b”)。然而,同时141b的臭氧消耗潜能(“ODP”)较高,约为0.1。因此,许多泡沫材料生产商正在研究选择较低ODP的戊烷代替141b,如在“Hydrocarbon Blown Rigid Polyurethane Foam for the BoardstockIndustry-A NovelApproach”(发表在Polyureathanes Expo-98,September 17-20,1998)中,R.E.Berrier等指出的。然而,这种产品用于泡沫也有缺陷,例如高成本和高的泡沫中k-因素性能(因此,制成的泡沫材料的热绝缘性能差)。
如在美国专利4,636,529也曾揭示HCFC-22可用作泡沫发泡剂。当仅使用这一种发泡剂时,其有某些缺陷,如高约1700的地球变暖潜能(“GWP)和约0.055的ODP。
因此,期望提供生产另一种泡沫发泡剂,这种发泡剂克服了22或仅用戊烷在如ODP、GWP、成本和k-因素性能方面的缺陷。
本发明提供了泡沫发泡剂组合物,该组合物包括:(a)约5-50%(摩尔)一氯二氟甲烷和(b)约95-50%(摩尔)的戊烷,其选自正戊烷、异戊烷和环戊烷中的一种或多种,还提供了泡沫预混组合物,该预混组合物包括多元醇和上述的发泡剂共混物;以及聚氨酯泡沫组合物,该泡沫组合物包括含异氰酸酯的A部分和含多元醇的B部分,以及所有或部分上述发泡剂共混物。
已经发现,上述戊烷和HCFC-22的共混物克服了仅使用其中任一种时的缺陷。如下所述,最重要的是,发现相对于仅使用戊烷,加入相对少量的22可降低由这种共混物制成的泡沫材料的k-因素(因此可提高热绝缘性能),同时还可利用戊烷的低ODP(零)和低GWP(例如环戊烷的GWP为11,而仅有22的GWP为1700)。其它优点包括降低仅使用戊烷的成本(尤其是环戊烷),提高在原料如聚酯多元醇(polyesterpolyol)(尤其是对正戊烷和异戊烷)中的溶解度,并且由于HCFC-22不是挥发性有机化合物(VOC),挥发性有机化合物含量小于纯的烃。
下面实施例表明,低温(0℃)时k-因素性能的未曾预料到的改进对许多泡沫应用如冰箱、冷冻机和冷冻储存设施特别明显。
如下面实施例所示,共混物中22的量宜根据具体的戊烷或戊烷混合物改变,但是一般在10-35%(摩尔)。
预混组合物中,以多元醇的重量为基准,发泡剂共混物的浓度范围一般在约2-60%(重量)(较好为5-40%(重量))。
聚氨酯泡沫组合物中,以聚氨酯泡沫组合物总重量为基准,共混物的有效浓度一般约为0.1-25%(重量)(较好为0.5-15%(重量))。
共混物中的戊烷组分和/或22组分可加入到A部分或B部分,或各部分中分布的部分中。还可以第三物料(与A部分或B部分完全分开)形式向泡沫设备加入发泡剂组合物。
预混物和泡沫配方的其它组分可以是常规使用的那些,这些组分和其比例为本领域技术人员公知。例如,催化剂、阻燃剂和表面活性剂通常为B部分的组分。
在下面非限制性实施例中详细说明本发明的实施。使用的配方(Iso指数都达到300)各含有170.51份M-489(可聚合的甲烷二苯基二异氰酸酯,可从Bayer Corporation购得);100份T-2541(羟基值为240的聚酯多元醇,可从Kosa购得);0.19份PC-5和0.33份PC-46(它们分别是五甲基二亚乙基三胺和乙二醇中的乙酸钾,是从AirProducts购得的催化剂);2.98份K-15(二丙二醇中的辛酸钾,从Air Products购得的催化剂);2份B-8462(聚硅氧烷-聚醚共聚物表面活性剂,可从Goldschmidt ChemicalCorporation购得);10份AB-80(三(1-氯-2-丙基)磷酸酯阻燃剂,可从Albright & WilsonAmericas,Inc.购得);和约24-25份发泡剂(其精确量具体列于下面,所有的份均以重量为基准)。
混合含异氰酸酯和75%发泡剂的A部分预混组分,并冷却至10℃。含多元醇、表面活性剂、阻燃剂和25%发泡剂的B部分预混组分也混合并冷却至10℃。
