Description

[根据细则37.2由ISA制定的发明名称]　制冷设备环保节能结构层及其应用[Name of invention made by ISA according to Rule 37.2] Environmental protection and energy-saving structural layer of refrigeration equipment and its application 技术领域Technical field
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。The invention belongs to the technical field of refrigeration equipment manufacturing, and in particular, the invention relates to an environmental protection and energy-saving structural layer of a refrigeration equipment.
背景技术Background technique
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)。Rigid polyurethane foam is generally used as a heat insulation layer between the outer casing and the inner lining of the refrigeration equipment, and rigid polyurethane foam is generally used as cyclopentane (CP), hydrofluoroalkane (HCFC, HFC) and hydrofluoroolefin (HFO). A blowing agent, in which the fourth-generation blowing agent hydrofluoroolefin HFO has a lower greenhouse effect potential (GWP) and zero ozone depletion potential (ODP), while the insulation layer using HFO foaming agent can improve refrigeration. The insulation performance of the equipment effectively reduces the energy consumption level of the refrigeration equipment, so the energy-saving and environmentally-friendly HFO will gradually replace the previous foaming agents such as hydrochlorofluorocarbons (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。However, when HFO is used as a foaming agent, HFO is highly corrosive to the lining of refrigeration equipment. In particular, HFO produces severe environmental stress on the acrylonitrile-butadiene-styrene (ABS) lining, in which HFO is more corrosive than before. CFC, HCFC and HFC are more serious. It is generally accepted in the industry that HFO foaming agents are difficult to apply to ABS-lined refrigeration equipment. In addition, the ABS lining has better forming properties and higher gloss, which makes the structural design of the refrigeration equipment more diversified and the taste is more high-end. Therefore, it is necessary to find a preparation application method for solving the compatibility between the ABS liner and the HFO foam insulation layer.
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。Since the HFO foaming agent is a fluorine-containing compound, it easily erodes the resin, has a low boiling point, is easily vaporized at normal temperature, and has a higher activity property. When the HFO foaming agent enters the ABS resin, the polymer will undergo plasticization under the influence of the HFO foaming agent due to the strong solvation effect of the HFO foaming agent. Among them, the butadiene rubber in ABS absorbs the foaming agent more easily, and the interface interaction between butadiene rubber and acrylonitrile-styrene becomes weaker, and it is more susceptible to stress in the stress concentration zone, especially the lining corner of the refrigeration equipment and the low temperature contact zone. Destruction, often manifested as multiple silver streaks and cracks.
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。Patent CN102173159 discloses ABS layered composite sheet as the inner tank of the refrigeration equipment, but the preparation process of the layered composite structure is complicated, and the ABS layered composite sheet is still difficult to resist the corrosion of the HFO foaming agent. The layered composite sheet needs to be prepared by a multi-layer coextrusion method, and the molding equipment has a large investment and a complicated molding process.

The problem is that it is effective against HFO foaming agent corrosion, and cracking does not occur under high and low temperature cycle changes.

When the content of the vinyl cyanide-aromatic vinyl polymer toughened by the EPDM rubber is too high, the cost is also remarkably increased.
