Description

一种铝塑膜用低结晶度聚丙烯
技术领域
本发明涉及铝塑膜领域技术，尤其是指一种铝塑膜用低结晶度聚丙烯。
背景技术
铝塑膜应用在软包电池外表面，对电池起到保护作用，电池在充放电过程中出现的发热、电池膨胀、电解液腐蚀等现象都会铝塑膜造成影响，这就需要对铝塑膜各方面的性能提出较高的要求。但是目前铝塑膜存在冲深成型性能差、封装温度高、耐电解液性能不够强、耐湿性较差等问题，以及，铝塑膜内层与电解液接触的热封层一般为流延聚丙烯，在冲深成型时，韧性和强度不佳的流延聚丙烯薄膜易发生应力发白，甚至冲破的现象。
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铝塑膜用低结晶度聚丙烯，其能解决铝塑膜存在冲深成型性能差、封装温度高、耐电解液性能不够强、耐湿性较差等问题。
为实现上述目的，本发明采用如下之技术方案：
一种铝塑膜用低结晶度聚丙烯，包括依次叠合的等离子体处理层、支撑层以及热封层，其中，
该等离子体处理层包含的各组分的质量百分数为：
氯化改性马来酸酐接枝聚丙烯 55-65％
改性添加剂 25-55％。
作为一种优选方案，所述改性添加剂为乙烯-辛烯共聚物、乙烯-丙烯-辛烯烃三元共聚物的一种或几种的混合物。
作为一种优选方案，所述支撑层包含的各组分的质量百分数为：
氯化改性马来酸酐接枝聚丙烯 60-75％
改性添加剂 25-40％。
作为一种优选方案，所述热封层包含的各组分的质量百分数为：
Figure BDA0002917107230000021
本发明与现有技术相比具有明显的优点和有益效果，具体而言，由上述技术方案可知，其主要是通过采用结晶度较低的氯化改性马来酸酐接枝聚丙烯，从而制得具有低结晶度的聚丙烯薄膜，聚丙烯结晶度的改变，会让聚丙烯的熔点改变，使得用该聚丙烯制备的铝塑膜可实现低温封装，并且，本发明还能提升铝塑膜的冲深成型性能、耐电解液性能、耐湿性等。
为更清楚地阐述本发明的结构特征和功效，下面结合附图与具体实施例来对本发明进行详细说明。
附图说明
图1是本发明之实施例的结构示意图。
附图标识说明：
10、等离子体处理层；20、支撑层；30、热封层；
具体实施方式
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述发明和简化描述，而不是指示或暗示所指的位置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以视具体情况理解上述术语在本发明中的具体含义。
请参照图1所示，其显示出了本发明之实施例的具体结构，包括依次叠合的等离子体处理层10、支撑层20以及热封层30，其中，
该等离子体处理层10包含的各组分的质量百分数为：
氯化改性马来酸酐接枝聚丙烯 55-65％
改性添加剂 25-55％。
在本实施例中，该改性添加剂为乙烯-辛烯共聚物、乙烯-丙烯-辛烯烃三元共聚物的一种或几种的混合物，改性添加剂可有效地破坏聚丙烯的结构规整性和对称性，使结晶能力下降，降低聚丙烯的结晶速度和结晶度，同时提高低温韧性。
具体而言，该支撑层20包含的各组分的质量百分数为：
氯化改性马来酸酐接枝聚丙烯 60-75％
改性添加剂 25-40％。
该热封层30包含的各组分的质量百分数为：
Figure BDA0002917107230000031
Figure BDA0002917107230000041
综上所述，本发明通过采用结晶度较低的氯化改性马来酸酐接枝聚丙烯，从而制得具有低结晶度的聚丙烯薄膜，聚丙烯结晶度的改变，会让聚丙烯的熔点改变，使得用该聚丙烯制备的铝塑膜可实现低温封装，并且，本发明还能提升铝塑膜的冲深成型性能、耐电解液性能、耐湿性等。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
