Description

一种冷库保温隔热涂料组合物及其制备方法
技术领域
本发明属于涂料组合物领域，具体涉及一种隔热涂料组合物及其制备和应用。
背景技术
建筑物的墙壁和屋顶棚需要有隔热功能，可以节约能源、提高舒适度，易于控制室内温度。可作隔热的材料很多，包括软木、稻壳、泡沫塑料、玻璃棉、矿渣棉及其制品、膨胀珍珠岩、炉渣、加气混凝土、泡沫玻璃等。其中软木、稻壳、泡沫塑料、玻璃棉、矿渣棉等可加工为板材，与墙体复合，或直接采用膨胀珍珠岩、炉渣、加气混凝土、泡沫玻璃材料构筑墙体。
隔热材料能隔热是因为材料内含有无数微小的气泡，这些气泡对热流的通过产生阻力，使能通过隔热材料的热量很少。当周围温度不同时，由于辐射和对流换热的作用会产生比较显著的热量传递，但气泡内的对流会随着气泡的变小而变得非常微弱。因此，隔热材料孔隙大小和形状对热导率有很大的影响。另一方面，孔隙尺寸大但开口串通时，则比孔隙尺寸小且封闭的热导率高。
食品冷库通常需要控制内部温度4℃，或者-20℃，其对隔热材料要求较严：1.热导率小，2.不散发有毒物质或异味，不易变质；3.块状材料要不容易变形，易于切割加工，并便于与基层粘结；4.地面、楼面采用的隔热材料，其抗压强度不应小于2.5kg/c㎡，5.难燃或非燃的材料。
目前采用的隔热材料，其耐热不燃性能不能达到A级标准，并存在施工复杂等不足之处。
发明内容
针对现有技术的不足，本发明的目的是提供一种冷库保温隔热涂料组合物。
本发明的另一目的是提出组合物的制备方法。
实现本发明上述目的的技术方案为：
一种冷库保温隔热涂料组合物，是由A组分和B组分组成，其中：
A组分：包括100重量份的三聚氰胺甲醛树脂；
B组分：包括重量份的20～40聚酯多元醇，10～20重量份的发泡剂，1～5重量份的稳泡剂，0～2重量份的催化剂，200～300重量份的异氰酸酯。
因为食品冷库还有对库存物保质的需求，因此隔热保温材料宜选用封闭、微孔、热导率较小的隔热材料。三聚氰胺甲醛树脂与芳基多元醇反应，可得到微孔泡沫材料，并通过选择适宜的稳泡剂、异氰酸酯，提高了泡孔的闭孔率和材料的强度。
本发明所述的质量份为本领域技术人员常用的质量单位，例如可以是克，千克，吨，或为了操作方便自定的质量单位。在同一个配方中，“份”表示的单位质量相同。
其中，所述聚酯多元醇为芳香族聚酯多元醇或聚醚多元醇。
其中，所述发泡剂为HCFC-141b(一氟二氯乙烷)、环戊烷、五氟丙烷、液体二氧化碳、二氯甲烷中的一种；所述稳泡剂为AK-8802、AK-8803、AK-8805、AK-338中的一种。所述稳泡剂可以为南京德美创世精细化工公司生产的稳泡剂。
其中，所述催化剂为N,N',N”-三(二甲氨基丙基)-六氢化三嗪(PC-41)、2,4,6-三(二甲氨基甲基)苯酚(DMP-30)、二月桂酸二丁基锡、辛酸亚锡、二乙酸二丁基锡中的一种或多种。
本发明所述的冷库保温隔热涂料组合物在制备保温隔热涂层中的应用。
所述的冷库保温隔热涂料组合物的应用方法，使在使用前将A组分和B组分混合，喷涂到基材表面，固化后即得保温隔热涂层。
本发明的有益效果在于：
本发明提出的保温恒温隔热胶的AB成分混合发泡后具有绝热效果，重量轻，强度大，耐化学品优良，具有不燃的性能。本发明提出的涂料组合物形成的涂层的保温隔热性强，比岩棉等保温材料性能更好，有望成为一类重要合成树脂胶绝热材料。
本发明保温恒温隔热胶根据不同需求，通过配比调整原料规格、密度、硬度、耐热性能等，泡沫塑料的密度可在很大范围内调整，
本涂料组合物可广泛应用于冰箱、冷柜、热水、蒸汽输送装置、冷库、冷藏车等行业。
