Description
技术领域
本发明属于氢能源存储行业，涉及储氢环节的主要材料，特别涉及一种冰凌架构的储氢材料的制造方法。
背景技术
氢能被称为人类21世纪的终极能源，氢能产业包括制氢、储氢和应用三个环节。制氢是储氢的基础，储氢是现在行业面临的瓶颈。因此，发明一种冰凌架构的储氢材料，可有效丰富储氢行业在用材与选材上的宽泛取向，它将促使该领域科研人员研发出新的科研成果。
目前市场上储氢产品很多，大体上有甲醇储氢、高压储氢、液化储氢、固态吸附储氢和金属氢化物储氢等，除了高压储氢目前已经商业化外，其他储氢产品目前还处于实验阶段。所以，如何研发出能够更好地促进储氢产品的行业需求，并在储氢行业得到广泛应用，成为科研人员亟待解决的问题。
有鉴于此，研发一种选用灵活、结构简单、安全性高、储氢容量大，且具有成本低、寿命长、操作简便、高效节能、绿色环保等特点的储氢产品成为该领域科研人员寻求的新目标。
发明内容
本发明的任务是提供一种冰凌架构的储氢材料制造方法，将聚乙烯、聚丙烯、尼龙等工程塑料和低温ADC（偶氮二甲酰胺）微粒子粉末发泡剂进行称量、配比与搅拌，搅拌好的料放入注塑机料筒，待材料加热后直接注入冰凌产品模具内，进而得到较佳的泡孔结构，形成冰凌框架备用；另一方面进行溶液配制，获得混合溶液即透气胶备用；再一方面配比复合材料备用；接着将备用的冰凌框架、混合溶液、复合材料各放置在各自的容器中进行复合融配，制成储氢成品，使冰凌框架沾满储氢复合材料并满布微孔，能可逆地大量吸收、储存和释放氢气，解决了按传统技术生产的储氢产品效果较为一般的问题。
本发明的技术解决方案如下：
一种冰凌架构的储氢材料制造方法，选用包括聚乙烯、聚丙烯、尼龙和热塑性塑料在内的工程塑料80份、低温ADC微粒子粉末发泡剂20份进行称量、配比与搅拌，将搅拌好的料放入注塑机料筒，待材料经加热熔融后直接注入冰凌产品模具内，模具需加热至材料的匹配温度，一次注入量为模具内容积的85%，且留有15%发泡空间，得到高的气泡核密度，进而得到佳好的泡孔结构，注塑结束，完成冰凌框架雏形；
接着开模取出成型产品进入第二道表面去膜工序，将注塑成型的冰凌框架进行浸泡，浸泡液由80%可乐与20%白醋组成，浸泡时间为48小时，浸泡时间届满即捞出，捞出沥干后放入去离子水中漂净晾干，晾干后的冰凌框架表面膜层被清除并成功打通框架内部通道，形成冰凌框架半成品备用；
另一方面进行溶液配制，取正硅酸乙酯55份、去离子水30份和甲醇15份及其他配料5份，按照该配制比例置于容器中进行混合搅拌，搅拌速度120rpm，搅拌时间45分钟，以此工艺获得混合溶液即透气胶备用；
再一方面开展复合材料配比，取石墨碳粉末和硼、碘、镁、钠粉末进行称量配比、搅拌，充分混匀后出筒备用；
然后将备用的冰凌框架、混合溶液、复合材料各放置在各自的容器中进行复合融配，复配时先将冰凌框架每10个穿成一串，再把成串的冰凌框架放进混合溶液容器中进行上下运动，运动10次后拎起抖动无液滴即可，接着直接放进复合材料工作箱内，放置时吊挂在箱体上方的吊钩上，吊钩成旋转状态，旋转的速度为60rpm，箱内由12个喷嘴从不同的角度喷出复合材料，使复合材料附和在冰凌框架内外表面，最后将这些经融配的冰凌框架通过85℃隧道窑烘干后制成储氢制成品。
所述注塑机采用超临界流体辅助的微孔注塑嘴。
按本发明的一种冰凌架构的储氢材料制造方法，将聚乙烯、聚丙烯、尼龙等工程塑料和低温ADC（偶氮二甲酰胺）微粒子粉末发泡剂进行称量、配比与搅拌，搅拌好的料放入注塑机料筒，待材料加热后直接注入冰凌产品模具内，进而得到较佳的泡孔结构，形成冰凌框架备用；另一方面进行溶液配制，获得混合溶液即透气胶备用；再一方面配比复合材料备用；接着将备用的冰凌框架、混合溶液、复合材料各放置在各自的容器中进行复合融配，制成储氢成品，使冰凌框架沾满储氢复合材料并满布微孔。经过这样的技术工艺处理，能够充分改善复合材料的力学性能，保持整个冰凌框架沾满储氢复合材料并满布微孔，让复合材料的晶体结构强度加强，使其成为在常温和氢气压力下，能可逆地大量吸收、储存和释放氢气的冰凌框架组合体化合物。
采用本发明的制造方法制成的储氢复合材料用于罐内安装时，只需将冰凌框架直接倒入罐体内，倒满为止，如果将来更换时，用勺子将其掏出就能轻松地完成作业。因此，按本发明方法生产的产品在应用时具有个体重量轻、安装简便、更换灵活、安全性高的特点，同时具备成本低、寿命长、高效节能、静音简洁、绿色环保、材料储氢量大的特点，在常温状态下能可逆地大量吸收、储存和释放氢气，促进氢能在发电、燃烧环节的安全使用，提高绿色能源的使用效率。
采用本发明的冰凌架构的储氢材料制造方法，为日常氢能源应用过程中对储能产品的选用提供了新的选项，具有广泛的应用价值。
附图说明

图2是本发明中的一种沾满储氢复合材料的冰凌框架的斜向俯视图。
具体实施方式
下面结合附图和实施例对本发明作详细说明。
本发明提供一种冰凌架构的储氢材料制造方法，选用聚乙烯、聚丙烯、尼龙和热塑性塑料等材料的工程塑料80份、低温ADC（偶氮二甲酰胺）微粒子粉末发泡剂20份进行称量、配比与搅拌，将搅拌好的料放入注塑机料筒，注塑机采用超临界流体辅助的微孔注塑嘴。待材料经加热熔融后直接注入冰凌产品模具内，模具需加热至材料的匹配温度，一次注入量为模具内容积的85%，且留有15%发泡空间，这样能提高注射速度，更有利于得到更高的气泡核密度，进而得到较佳的泡孔结构，注塑结束，表明冰凌框架雏形完成。
参看图1和图2，图中显示了一种沾满储氢复合材料的冰凌框架，冰凌框架内壁布设数排朝向中心的凸片，凸片的向中心端部设有数个凹口，每排凸片的底端和顶端分别与冰凌框架的底面和顶面齐平。如图中所示，凹片的凹口呈直角形状，也可以呈圆弧形状，还可以呈锯齿形状，有利于在更多的比表面积上沾满储氢复合材料。
在制造过程中，接下来开模取出成型产品进入第二道表面去膜工序，将注塑成型的冰凌框架进行浸泡，浸泡液由80%可乐与20%白醋组成，浸泡时间为48小时，浸泡时间届满即捞出，捞出沥干后放入去离子水中漂净晾干，晾干后的冰凌框架表面膜层被清除并成功打通框架内部通道，形成冰凌框架半成品备用。
另一方面进行溶液配制，取正硅酸乙酯55份、去离子水30份和甲醇15份及其他配料5份，按照该配制比例置于容器中进行混合搅拌，搅拌速度120rpm，搅拌时间45分钟，以此工艺获得混合溶液（透气胶）备用。
再一方面开展复合材料配比，取石墨碳粉末和硼、碘、镁、钠等粉末进行称量配比、搅拌，充分混匀后出筒备用。
然后将备用的冰凌框架、混合溶液、复合材料各放置在各自的容器中进行复合融配，复配时先将冰凌框架每10个穿成一串，再把成串的冰凌框架放进混合溶液容器中进行上下运动，运动10次后拎起抖动无液滴即可，接着直接放进复合材料工作箱内，放置时吊挂在箱体上方的吊钩上，吊钩成旋转状态，旋转的速度为60rpm，箱内由12个喷嘴从不同的角度喷出复合材料，使复合材料附和在冰凌框架内外表面，最后将这些经融配的冰凌框架通过85℃隧道窑烘干后制成储氢制成品。
经过这样的技术工艺处理，能够充分改善复合材料的力学性能，保持整个冰凌框架沾满储氢复合材料并满布微孔，让复合材料的晶体结构强度加强，使其成为在常温和氢气压力下，能可逆地大量吸收、储存和释放氢气的冰凌框架组合体化合物。
综上所述，按本发明的冰凌架构的储氢材料制造方法制成储氢成品，使冰凌框架沾满储氢复合材料并满布微孔，能可逆地大量吸收、储存和释放氢气。采用本发明的制造方法生产的储氢产品可用于罐内安装，具有个体重量轻、安装简便、更换灵活、安全性高的特点，同时具备成本低、寿命长、高效节能、静音简洁、绿色环保、材料储氢量大的特点，在常温状态下能可逆地大量吸收、储存和释放氢气，促进氢能在发电、燃烧环节的安全使用，提高绿色能源的使用效率。
当然，本技术领域内的一般技术人员应当认识到，上述实施例仅是用来说明本发明，而并非用作对本发明的限定，只要在本发明的实质精神范围内，对上述实施例的变化、变型等都将落在本发明权利要求的范围内。

1.一种冰凌架构的储氢材料制造方法，其特征在于：选用包括聚乙烯、聚丙烯、尼龙和热塑性塑料在内的工程塑料80份、低温ADC微粒子粉末发泡剂20份进行称量、配比与搅拌，将搅拌好的料放入注塑机料筒，待材料经加热熔融后直接注入冰凌产品模具内，模具需加热至材料的匹配温度，一次注入量为模具内容积的85％，且留有15％发泡空间，得到高的气泡核密度，进而得到佳好的泡孔结构，注塑结束，完成冰凌框架雏形；
接着开模取出成型产品进入第二道表面去膜工序，将注塑成型的冰凌框架进行浸泡，浸泡液由80％可乐与20％白醋组成，浸泡时间为48小时，浸泡时间届满即捞出，捞出沥干后放入去离子水中漂净晾干，晾干后的冰凌框架表面膜层被清除并成功打通框架内部通道，形成冰凌框架半成品备用；
另一方面进行溶液配制，取正硅酸乙酯55份、去离子水30份和甲醇15份及其他配料5份，按照该配制比例置于容器中进行混合搅拌，搅拌速度120rpm，搅拌时间45分钟，以此工艺获得混合溶液即透气胶备用；
再一方面开展复合材料配比，取石墨碳粉末和硼、碘、镁、钠粉末进行称量配比、搅拌，充分混匀后出筒备用；
然后将备用的冰凌框架、混合溶液、复合材料各放置在各自的容器中进行复合融配，复配时先将冰凌框架每10个穿成一串，再把成串的冰凌框架放进混合溶液容器中进行上下运动，运动10次后拎起抖动无液滴即可，接着直接放进复合材料工作箱内，放置时吊挂在箱体上方的吊钩上，吊钩成旋转状态，旋转的速度为60rpm，箱内由12个喷嘴从不同的角度喷出复合材料，使复合材料附和在冰凌框架内外表面，最后将这些经融配的冰凌框架通过85℃隧道窑烘干后制成储氢制成品；
所述冰凌框架内壁布设数排朝向中心的凸片，凸片的向中心端部设有数个凹口，每排凸片的底端和顶端分别与冰凌框架的底面和顶面齐平；冰凌框架沾满储氢复合材料并满布微孔，能可逆地大量吸收、储存和释放氢气。
2.按权利要求1所述的冰凌架构的储氢材料制造方法，其特征在于：所述注塑机采用超临界流体辅助的微孔注塑嘴。
