Description

一体式折叠缠绕隔热垫的制备方法及隔热垫
技术领域
本发明涉及隔热垫制备领域技术，尤其是指一种一体式折叠缠绕隔热垫的制备方法及隔热垫。
背景技术
电池隔热垫呈方形片状，通常夹设于电池模组的电芯之间，电池隔热垫具有优良的隔热和缓冲功能，可防止电芯热失控；由于电池隔热垫的组成材料不同，其制备工艺也有所不同。
传统技术中，如图1所示，其隔热垫包括两片包封膜材、阻燃气凝胶和缓冲框，缓冲框在裁切时，缓冲框材料的利用率低，导致增加了电池隔热垫的制作成本；如图2所示，其隔热垫包括两片包封膜材和阻燃气凝胶，但其封边处为无隔热区域，影响整体的隔热效果；如图3所示，其通过两片形状不同的包封膜材对阻燃气凝胶进行包封，材料结构多增加物料管控和组合生产数量比例管控，及此种包封方式在隔热芯材的四个角落处无法形成密封而漏气，产品包封后的厚度易因漏气而产生厚度不良，且气凝胶颗粒从角落喷出，影响隔热垫的使用寿命；以及，因两片不同的包封膜材的结构限制，难以实现自动化包封，人工成本高。
因此，有必要设计一种新的技术方案来解决上述问题。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种一体式折叠缠绕隔热垫的制备方法及隔热垫，其采用一体式包封膜材对隔热芯材进行包封，确保了产品的密封性，包封膜材结构简单、易于生产制作；以及，隔热芯材具有定制的压缩率从而取代了缓冲材料，降低了材料成本。
为实现上述目的，本发明采用如下之技术方案：
一种一体式折叠缠绕隔热垫的制备方法，包括准备工作和制作步骤；
所述准备工作包括：
A，包封膜材涂覆胶层；
B，隔热芯材的检验测试；
选用具有组装所需压缩率的隔热芯材，对隔热芯材的厚度、密度、导热系数、憎水率、拉伸强度进行测试；
C，制备隔热芯材；对B中检测合格的隔热芯材制成所需的长度、宽度尺寸；
D，制备包封膜材；
D-1，依据隔热芯材的长度、宽度、厚度尺寸，设定A中包封膜材的长度、宽度尺寸；模切的包封膜材呈“十”字型结构，所述包封膜材包括主体部和自主体部的四边分别一体向外延伸并依次排布的第一延伸边、第二延伸边、第三延伸边、第四延伸边；所述主体部的长度、宽度尺寸等于隔热芯材的长度、宽度尺寸，所述第一延伸边和第三延伸边的长度尺寸比隔热芯材的长度尺寸小3-10mm，所述第一延伸边和第三延伸边的延伸长度比隔热芯材的厚度大且两者可相互折叠重合；所述第二延伸边和第四延伸边的延伸长度比隔热芯材的厚度大5-30mm，所述第二延伸边和第四延伸边的两端一体向外延伸有角封边，所述角封边连接第一延伸边和第三延伸边；
