Description
技术领域
本发明实施例涉及自发热材料加工技术领域,具体涉及一种多功能复合结构发热体及其制造方法。
背景技术
目前市场上的暖贴内料主要成分为铁粉、活性炭、蛭石、水、吸水树脂、氯化钠等,该内料结构为原电池的反应原理,遇空气中的氧气迅速反应放热,主要用于人们日常生活的保暖及热敷方面。
但该内料结构由于在混料制造过程中已经将原电池反应阳极结构、阴极结构及闭环电路环境(电解质溶液)的所有要素简单的一次性组合在一起,从而导致唯一的原电池反应的“开关”仅剩下阻隔氧气这一个因素,因此在生产、储运过程中必须严格将空气与该类型的暖贴阻隔开。
比如,在生产混料过程中需要密闭、真空或充氮混料,以阻止混合过程中物料剧烈反应放热的现象,导致生产损耗过高、制造工艺控制难度大、产出成品质量性能大幅度下降或不稳定等问题。又比如,在成品储运过程中,为阻止产品缓慢反应失效,需要使用高阻隔性的铝塑膜或特殊复合膜,从而使得包装材料成本比常规日化产品提升了30%-50%,直接增加了包材生产厂家的制造难度,也提高了暖贴生产企业制造成本,同时间接提高了消费者的消费成本。再比如,由于该内料中活性炭需要极高的比表面积才能带来相应的原电池催化效果,但高比表面积也带来了高吸附率的负面影响,导致了该类产品附加功能设计制造过程中添加的香精、精油、各类提取物及功效物质等均在生产混料及长期储运过程中被活性炭缓慢吸附锁定失效,导致产品在使用过程中无法达到预期的设计效果。
因此,在暖贴系列产品的生产中,亟须设计一种多功能复合结构发热体制造方法来解决此类问题。
发明内容
为此,本发明实施例提供一种多功能复合结构发热体及其制造方法,以解决现有技术中存在的相关技术问题。
为了实现上述目的,本发明实施例提供如下技术方案:
根据本发明实施例的第一方面,提供了一种多功能复合结构发热体,包括:
发热内膜袋,其为边缘封合的双层结构;
基础发热体,其封合在所述发热内膜袋内,且平铺设置;
液体复合装置,其封合在所述发热内膜袋内中心,所述液体复合装置和基础发热体分隔设置。
进一步地,还包括多个导流延伸端,多个所述导流延伸端均匀设于所述液体复合装置外边缘,所述导流延伸端伸入所述基础发热体内。
进一步地,所述液体复合装置通过包埋、嵌套、叠压、粘接或热封定位方式设于所述基础发热体中心。
进一步地,所述液体复合装置包括液体阻隔膜和液体模块,所述液体模块包覆在所述液体阻隔膜内,并当所述液体阻隔膜被挤压破裂时,所述液体模块顺所述导流延伸端渗透进入所述基础发热体。
进一步地,所述液体阻隔膜为聚乙烯、聚氯乙烯、聚苯乙烯、聚丙烯、聚乙二醇、聚乙烯醇中的一种或几种。
进一步地,所述液体模块含有纯水、无机盐、功效添加物、增溶剂和填充结构物中的一种或几种。
进一步地,所述发热内膜袋为微透气膜、打孔透气膜、透气纸、无纺布或不透气膜。当发热内膜袋对液体复合装置和基础发热体进行包覆时,至少保证其中一层为透气结构,而另一层可为不透气膜或透气膜。
进一步地,所述基础发热体包括各成分比例范围如下:
根据本发明实施例的第二方面,提供了一种多功能复合结构发热体制造方法,用于对如上的多功能复合结构发热体进行制造,包括如下步骤:
1)设置双层的发热内膜袋,其边缘封合后内部形成容纳空间;
2)将基础发热体填充在所述发热内膜袋内,且平铺设置在所述容纳空间中;
3)将液体复合装置封合在所述发热内膜袋内中心,所述液体复合装置和基础发热体分隔设置。
进一步地,其中在步骤3)中,还包括:
将液体模块包覆在液体阻隔膜内,以使所述液体阻隔膜被挤压破裂时,所述液体模块顺所述导流延伸端渗透进入所述基础发热体。
本申请将基础发热体、液体复合装置结构独立分离并封合在发热内膜袋内,为生产制造及消费者使用带来多重有益效果:
1、工艺简化,避免了该类产品包装生产过程中的密闭、真空或充氮的工艺要求,大大降低了生产制造难度,且将混合物料在制造过程中的热损失降至零损失;
2、产品包装过程中可使用常规的塑料包装膜即可,大大降低了产品外包装成本;
3、降低香精、精油、植物提取物等多种物质添加难度,避免活性炭缓慢吸附带来的功效物质失效问题;
4、一般暖贴实际保质期仅为18个月,18个月后产品发热时长即衰减到低于产品标识发热时长,使用该制造方法生产的暖贴类产品保质期可以提高至36-72个月,可将产品保质期提高2-4倍,发热时长仍能够符合产品标识发热时长;
5、扩展暖贴发热片半成品与各类日化品开发技术结合,形成新型产品的应用可能性。
与现有技术相比,本发明改进了传统暖贴内料的内部结构,具有混料工艺简单,包装材料要求低,生产成品保质期长,多种功效成分任意添加的效果。

具体实施方式
以下由特定的具体实施例说明本发明的实施方式,熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本发明的其他优点及功效,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
为了解决现有技术中存在的相关技术问题,根据本发明实施例的第一方面,提供了一种多功能复合结构发热体,其改进了传统的传统暖贴内料的内部结构,具有混料工艺简单,包装材料要求低,生产成品保质期长,多种功效成分任意添加的效果。如图1-2,具体包括:
发热内膜袋100,其为边缘封合的双层结构,如图1所示的,两层发热内膜袋100之间形成容纳空间,其边缘通过热封等方式进行封合,从而可在加工时,将基础发热体200封合在其内。其中,为了降低包装成本,所述发热内膜袋100为微透气膜、打孔透气膜、透气纸、无纺布或不透气膜等。
基础发热体200,其封合在所述发热内膜袋100内,其主要成分为铁粉、活性炭、分散剂、保水剂、导水剂、粘合剂、无机盐混合物制作的粉状、颗粒状、片状、球状、块状等类型的基础发热模块,该内料结构为原电池的反应原理,遇空气中的氧气迅速反应放热,且平铺设置,以使其在使用时能够提供更多的接触面积,提高产热效率。在此实施例中,基础发热体200包括各成分比例范围如下:
基础发热体200中各成分种类可采用如下:
铁粉:50-300目的铸铁铁粉、还原铁粉中的一种或几种;
活性炭:50-300目的木质、煤质活性炭粉中的一种或几种;
分散剂:10-200目的蛭石、硅藻土、高岭土、滑石粉、碳酸钙粉末、石英粉中的一种或几种;
保水剂:聚丙烯酸类、聚乙二醇类、聚乙烯醇类、淀粉接枝类高分子吸水树脂中的一种或几种;
导水剂:植物纤维、化学纤维、矿物纤维、中空玻璃纤维中的一种或几种;
粘合剂:瓜尔豆胶、阿拉伯胶、黄原胶中的一种或几种;
无机盐:氯化钠、碳酸钠、氯化钾、氯化镁、硫酸镁、氯化钙中的一种或几种。
当然为了更好的实现技术效果,也可对基础发热体200的配方进行改进。
最为重要的是,还包括液体复合装置300,其封合在所述发热内膜袋100内中心,所述液体复合装置300和基础发热体200分隔设置。因此,在加工制造过程中,可分别单独的对液体复合装置300和基础发热体200进行加工,工艺更加简化,避免了该类产品包装生产过程中的密闭、真空或充氮的工艺要求,大大降低了生产制造难度,且将混合物料在制造过程中的热损失降至零损失。同时,由于液体复合装置300为单独生产,可降低香精、精油、植物提取物等多种物质添加难度,保存时避免活性炭吸附带来的功效物质失效问题。
为了在使用时能够使被挤破的液体复合装置300中的液体更加均匀进入到基础发热体200中,具体地,还设置了多个导流延伸端400,多个所述导流延伸端400均匀设于所述液体复合装置300外边缘,所述导流延伸端400伸入所述基础发热体200内。进一步地,所述液体复合装置300通过包埋、嵌套或叠压方式设于所述基础发热体200中心。
进一步地,所述液体复合装置300包括液体阻隔膜301和液体模块302,所述液体模块302包覆在所述液体阻隔膜301内。所述液体阻隔膜301为聚乙烯、聚氯乙烯、聚苯乙烯、聚丙烯、聚乙二醇、聚乙烯醇中的一种或几种。所述液体模块302含有纯水、无机盐、功效添加物、增溶剂和填充结构物中的一种或几种。在具体使用时,通过外力对液体阻隔膜301进行挤压而破裂,液体模块302顺所述导流延伸端400渗透进入所述基础发热体200。
液体复合装置300内部组成种类可如下:
无机盐:氯化钠、碳酸钠、氯化钾、氯化镁、硫酸镁、氯化钙中的一种或几种;
功效添加物:植物精油、香精、植物提取物中的一种或几种;
增溶剂:TWEEN-20、TWEEN-80、AEO-3、AEO-7、AEO-9、CO-40中的一种或几种;
填充结构物:聚丙烯酸树脂、聚乙烯醇树脂、卡波姆、琼脂中的一种或几种。
产品使用时,通过外力按压破坏液体复合装置300,使得其内部混合物中的水溶液与基础发热体200渗透结合,并与外部空气接触启动原电池反应放热;与此同时液体复合装置300中的功效物质伴随液体扩散及发热体发热快速散发,同步达到产品预设功效。如,芳香精油释放:镇静、舒缓、助眠、提神等功效;香料香精释放:赋香、加香等功效;植物提取物释放:快速蒸汽散发、熏蒸、经皮给药等功效。
根据本发明实施例的第二方面,提供了一种多功能复合结构发热体制造方法,用于对如上的多功能复合结构发热体进行制造,包括如下步骤:
1)设置双层的发热内膜袋100,其边缘封合后内部形成容纳空间;
2)将基础发热体200填充在所述发热内膜袋100内,且平铺设置在所述容纳空间中;
3)将液体复合装置300封合在所述发热内膜袋100内中心,所述液体复合装置300和基础发热体200分隔设置。
进一步地,其中在步骤3)中,还包括:
将液体模块302包覆在液体阻隔膜301内,以使所述液体阻隔膜301被挤压破裂时,所述液体模块302顺所述导流延伸端400渗透进入所述基础发热体200。
本申请将基础发热体200、液体复合装置300结构独立分离并封合在发热内膜袋100内,为生产制造及消费者使用带来多重有益效果。
同时,现有技术中的一般暖贴实际保质期仅为18个月,18个月后产品发热时长即衰减到低于产品标识发热时长,而使用本申请的制造方法,由于基础发热体200和液体复合装置300为单独包装,生产的暖贴类产品保质期可以提高至36-72个月,产品保质期提高2-4倍,发热时长仍能够符合产品标识发热时长。
当然,为了提高其适用性,还可扩展暖贴发热片半成品与各类日化品开发技术结合,形成新型产品的应用可能性。
与现有技术相比,本发明改进了传统暖贴内料的内部结构,具有混料工艺简单,包装材料要求低,生产成品保质期长,多种功效成分任意添加的效果。
当然,现有技术中爆珠为水溶膜,仅能包裹油性物质,解决了油性物质的添加问题,而本申请的结构和制造方法扩展了可直接添加各类物质的方式方法(将物质添加到液体复合装置300中),并且爆珠形式在解决油性物质添加的时候,采用简单的外壳包裹方式;本技术在添加油性物质时,采用的是乳化液化水溶的方式进行添加的,采用的技术路径要优于现有技术的方案。
虽然,上文中已经用一般性说明及具体实施例对本发明作了详尽的描述,但在本发明基础上,可以对之作一些修改或改进,这对本领域技术人员而言是显而易见的。因此,在不偏离本发明精神的基础上所做的这些修改或改进,均属于本发明要求保护的范围。
