技术领域
本发明涉及一种点焊胶，特别是涉及一种发泡型点焊胶。
背景技术
该发明与现有技术相比，发泡率达60％以上，可以应用于焊缝间隙比较大的部位，而传统不发泡点焊胶只能适用于焊缝间隙比较小的部位。相比较适用范围更广泛。
发明内容
为解决上述问题，本发明的目的在于提供一种发泡型点焊胶；所述点焊胶相比传统不发泡点焊胶可以在焊缝间隙大的部位适用。
本发明的目的是通过以下措施来实现的：
本发明的一种发泡型点焊胶，所述发泡型点焊胶按质量百分比计，其组成为：橡胶5～10％；环氧树脂3～8％；填料35～45％；除湿剂1～5％；导电剂3～8％；共聚树脂3～10％；固化剂0.2～0.8％；增塑剂32～42％；发泡剂0.2～0.8％。替代传统不发泡点焊胶，通过胶自身的发泡来填充更大的焊缝间隙，从而适用范围更广泛。
所述填料为高岭土或者硅藻土或者滑石粉中的一种或者两种。
所述增塑剂为邻苯二甲酸二(2-乙基己)酯。
所述导电剂为纳米银。
所述共聚树脂为氯乙烯共聚树脂。
所述固化剂为环氧树脂。
所述除湿剂为氧化铝。
所述发泡剂为聚氨酯发泡剂。
所述的一种发泡型点焊胶的制备方法为：
(1)将配方量的：橡胶加热、搅拌，温度达到70-85℃时，加入配方量的填料、增塑剂、
环氧树脂、导电剂，搅拌混匀；
(2)再加入配方量的吸湿剂，继续搅拌至完全吸收混匀；
(3)加入配方量的共聚树脂、固化剂，继续搅拌，至混匀，出料降温至常温；
(4)按照配方比将步骤(3)中得到的产品与发泡剂混合，常温下搅拌10小时以后，得
到所述发泡型点焊胶。
本发明的有益效果：
本发明所述的一种发泡型点焊胶，替代传统不发泡点焊胶，通过胶自身的发泡来填充更大的焊缝间隙，从而适用范围更广泛。
具体实施方式
实施例1
一种发泡型点焊胶，所述发泡型点焊胶按质量百分比计，其组成为：橡胶6％；环氧树脂3％；填料35％；除湿剂5％；导电剂3％；共聚树脂5％；固化剂0.2％；增塑剂42％；发泡剂0.8％。替代传统不发泡点焊胶，通过胶自身的发泡来填充更大的焊缝间隙，从而适用范围更广泛。
所述填料为高岭土或者硅藻土或者滑石粉中的一种或者两种。
所述增塑剂为邻苯二甲酸二(2-乙基己)酯。
所述导电剂为纳米银。
所述共聚树脂为氯乙烯共聚树脂。
所述固化剂为环氧树脂。
所述除湿剂为氧化铝。
所述发泡剂为聚氨酯发泡剂。
所述的一种发泡型点焊胶的制备方法为：
(1)将配方量的：橡胶加热、搅拌，温度达到70-85℃时，加入配方量的填料、增塑剂、环氧树脂、导电剂，搅拌混匀；
(2)再加入配方量的吸湿剂，继续搅拌至完全吸收混匀；
(3)加入配方量的共聚树脂、固化剂，继续搅拌，至混匀，出料降温至常温；
(4)按照配方比将步骤(3)中得到的产品与发泡剂混合，常温下搅拌10小时以后，得到所述发泡型点焊胶。
表1实施例1中制备的发泡型点焊胶与传统点焊胶性能对比
表一是以某焊缝间隙为2mm，点焊胶涂胶厚度为1.5mm为例的比较。通过表一可以看出在焊缝间隙为2mm，点焊胶涂胶厚度为1.5mm前提条件下，传统不发泡点焊胶未充满焊缝间隙，而发泡型点焊胶已充满焊缝间隙。
