Description

一种制冷设备环保节能结构层及其应用 技术领域
本发明属于制冷设备制造技术领域，具体地，本发明涉及一种制冷设备环保节能结构层。
背景技术
制冷设备外壳和内衬之间一般使用硬质聚氨酯泡沫作为隔热层，而硬质聚氨酯泡沫目前一般采用环戊烷(CP)、氢氟烷烃(HCFC、HFC)和氢氟烯烃(HFO)作为发泡剂，其中第四代发泡剂氢氟烯烃HFO由于具有较低的温室效应潜值(GWP)以及零消耗臭氧潜值(ODP)，同时使用HFO发泡剂的隔热层能提高制冷设备保温性能，有效降低制冷设备能耗等级，因此节能环保的HFO将逐步会取代之前的氢氟氯烃等发泡剂(CFC、HCFC、HFC)。
但是HFO作为发泡剂时，HFO对制冷设备内衬有严重腐蚀性，特别是HFO对丙烯腈-丁二烯-苯乙烯(ABS)内衬产生严重的环境应力，其中HFO腐蚀性比之前的CFC、HCFC和HFC更为严重。目前行业内普遍认为HFO发泡剂难以应用在ABS内衬的制冷设备。另外，ABS内衬具有较好的成型性能和较高的光泽度，这使得制冷设备的结构设计更为多样化和品味更加高端化。因此，必须寻找解决ABS内衬与HFO发泡隔热层相互兼容的制备应用方法。
由于HFO发泡剂属于含氟化合物，容易侵蚀树脂，其沸点较低，常温下容易气化，活动性能更大。当HFO发泡剂进入ABS树脂内，由于HFO发泡剂具有较强的溶剂化作用，高分子在HFO发泡剂影响下会发生增塑。其中ABS中丁二烯橡胶更容易吸收发泡剂，丁二烯橡胶与丙烯腈-苯乙烯界面相互作用变弱，在应力集中区特别是制冷设备内衬边角部位以及低温接触区域更容易遭受破坏，常常表现为多重银纹和开裂。
专利CN102173159公开了ABS层状复合板材作为制冷设备内胆，但层状复合结构制备过程较为复杂，而且ABS层状复合板材仍难以抵抗HFO发泡剂腐蚀。层状复合板材需要采用多层共挤方法制备，成型设备投入较大，成型工艺复杂。
发明内容
本发明旨在克服上述现有技术的缺陷，提供一种由改性的ABS树脂制成的内衬板材，所述内衬板材克服了ABS内衬板材与HFO发泡隔热层难以兼容的难题，有效耐HFO发泡剂腐蚀，在受到应力和高低温循环变化下，不会发生开裂。
本发明的另一目的在于提供一种包含由所述改性的ABS树脂制成的内衬板材的制冷设备环保节能结构层。
本发明的另一目的在于提供所述制冷设备环保节能结构层在制备冰箱、冰柜和酒柜中的应用。
本发明的上述发明目的通过以下方案予以实现。
乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物在制备制冷设备内衬板材中的应用，所述乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物与ABS共混制备成改性芳香族乙烯基树脂再制备成制冷设备内衬板材；所述改性芳香族乙烯基树脂中，相对于乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物与ABS的总量，乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的重量含量为20～95％。
发明人发现，采用乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物替代部分ABS树脂，可极大的提升材料的耐高低温、抗老化与耐化学腐蚀性能。当所述改性芳香族乙烯基树脂中，乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的重量含量为20～95％时，内衬板材不会产生开裂现象。
优选地，所述乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的重量含量为30～95％。发明人发现，当乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的用量在此范围内时，可进一步使内衬板材平整光滑。
乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的含量过高时，会给改性芳香族乙烯基树脂的成型性能带来负面影响，板材难以加工吸塑成型。考虑成型加工性能，本发明乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的含量可进一步优选为30～60％。乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的含量过高时，成本也会显著上升。综合性能和成本的优势，本发明乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的用量进一步优选为30～40％。
优选地，所述改性芳香族乙烯基树脂中，ABS的重量含量至少为5％。
所述改性芳香族乙烯基树脂中，还可以含有适量的助剂，所述助剂可以是润滑剂、抗氧剂等本领域常用的助剂。
所述乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物中，所述乙烯基氰为丙烯腈或甲基丙烯腈，所述芳香族乙烯为苯乙烯、α-甲基苯乙烯或乙烯基甲苯，所述不饱和烯酸酯为丙烯酸甲 酯、丙烯酸乙酯、丙烯酸丙酯、丙烯酸丁酯、丙烯酸异丁酯、甲基丙烯酸甲酯、甲基丙烯酸乙酯、甲基丙烯酸丙酯、甲基丙烯酸丁酯或甲基丙烯酸异丁酯。
一种制冷设备环保节能结构层，包括由HFO发泡硬质聚氨酯泡沫层与由所述改性芳香族乙烯基树脂制成的内衬板材。
所述HFO发泡硬质聚氨酯泡沫层可以沿用已知技术的HFO发泡硬质聚氨酯泡沫层。通常地，这种HFO发泡硬质聚氨酯泡沫层由多元醇、含HFO的发泡剂、催化剂和异氰酸酯反应制成。
优选地，所述含HFO的发泡剂为HFO类发泡剂构成的单一发泡剂或由HFO类发泡剂与其他非HFO类发泡剂组成的混合发泡剂。
作为一种可选方案，所述HFO类发泡剂为反式1-氯-3,3,3-三氟丙烯(HFO-1233zd)、六氟丁烯(HFO-1336mmz)的至少一种。
作为一种可选方案，所述混合发泡剂为HFO类发泡剂与烷烃和/或HFC类发泡剂组成的混合物。
更优选地，所述烷烃为戊烷，所述戊烷为选自环戊烷、异戊烷和正戊烷的至少一种。
更优选地，所述HFC类发泡剂为HFC-245、HFC-365mfc、HFC-134a的至少一种。
本发明所述的内衬板材的成型工艺可以依照现有的ABS内衬板材的成型工艺进行。
所述制冷设备环保节能结构层在制备冰箱、冰柜和酒柜中的应用。
与现有技术相比，本发明具有如下有益效果：
本发明采用改性芳香族乙烯基树脂替代部分ABS树脂，显著提高了内衬板材的耐化学腐蚀性，解决了现今制冷设备ABS内衬板材不能使用HFO发泡剂的问题；使用改性芳香族乙烯基树脂提高了制冷设备环保节能性能；本发明内衬板材的成型工艺与目前常用ABS内衬板材一致，保留了良好的成型性，可使制冷设备的结构设计更为多样化和品味更加高端化。

将上述硬质聚氨酯泡沫层与上述改性芳香族乙烯基树脂内衬板材复合成制冷设备环保节能结构层。
对上述实施例1～7和对比例1、对比例2组装制冷设备环保节能结构层进行高低温交替5个循环测试(-40℃～70℃，12h)，观察结构层内衬板材表面是否出现裂纹(目测)及是否光滑平整(指触及目测)，其检测结果见表1。
表1实施例和对比例内衬板材检测结果
  检测结果
实施例1 无明显开裂，光滑平整
实施例2 无明显开裂，光滑平整
实施例3 无明显开裂，光滑平整
实施例4 无明显开裂，光滑平整
实施例5 无明显开裂，光滑平整
实施例6 无明显开裂，光滑平整
实施例7 无明显开裂，表面略微粗糙
对比例1 开裂
对比例2 开裂
根据实施例和对比例的内衬板材检测结果可知，当所述改性芳香族乙烯基树脂中，乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的重量含量为20～95％时，所制备的内衬板材耐高低温性好，不容易出现裂纹；当乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的重量含量为30～95％时，内衬板材的表面光滑平整；不使用乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物或使用的乙烯基氰-芳香族乙烯-不饱和烯酸酯聚合物的量不够时，均达不到对制冷设备内衬板材的要求。
