Description

一种无薄膜包覆透气型硅胶胸垫及其制作方法
技术领域
本发明涉及一种硅胶胸垫及其制作方法,尤其涉及一种无薄膜包覆透气型硅胶胸垫及其制作方法。
背景技术
目前的内衣胸垫(一般作为文胸附件使用),从材质上区分可分为:海绵(含表面贴布)定型胸垫、无纺纤维绵(含表面贴布)定型胸垫、薄膜袋(含表面贴布)内置填充物胸垫以及薄膜包覆普通有机硅凝胶胸垫四大类。而这些类型的胸垫产品又各自存在明显缺陷:海绵(含表面贴布)定型胸垫易黄变、易变形(特别是水洗过程)、耐用性差;无纺纤维绵(含表面贴布)定型胸垫虽基本解决了海绵材料的黄变问题,但弹性手感不足,特别是水洗后变形度更高,耐用性更差;薄膜袋(含表面贴布)内置填充物胸垫虽在洗涤、弹性方面无明显缺陷,但由于其薄膜材料存在不透气的问题,易引起人体闷热感,在柔软舒适度方面也不如其他类产品,且无法有效形成贴合人体的曲面造型;而薄膜包覆普通有机硅凝胶胸垫虽然基本解决了手感、使用变形和耐用性问题,但也仍存在着重量过大、以及薄膜透气性差的问题,另外,外覆薄膜一般采用TPU材质,还存在材料水解问题,不宜进行遇水清洁。
发明内容
为了克服上述现有技术的缺陷,本发明的目的是提供一种重量较轻、具有透气功能的,易于清洗且具有极高柔软度的无薄膜包覆的硅胶胸垫及其制作方法。
为达到上述目的,本发明采用以下技术方案:
一种无薄膜包覆透气型硅胶胸垫,包括硅胶胸垫本体,其特征在于:所述硅胶胸垫本体至少包括沿厚度方向由下至上层叠并相结合在一起的有机硅凝胶底层和有机硅凝胶表层,所述有机硅凝胶底层的硬度大于所述有机硅凝胶表层,所述有机硅凝胶底层内含有轻质高分子微珠填充料;所述硅胶胸垫本体沿自身厚度方向贯穿有透气孔。
其中,所述有机硅凝胶底层中与所述有机硅凝胶表层相结合的表面具有凸起或下凹的花纹结构。
进一步地,所述有机硅凝胶表层为透明或半透明结构。采用透明或半透明结构的有机硅凝胶表层后,透过表层可看到有机硅凝胶底层的立体花纹结构的图案造型,外观更加美观。
较佳地,所述硅胶胸垫本体的外表面涂覆有手感硅油。手感硅油可增加硅胶胸垫本体的表面爽滑度。
其中,所述有机硅凝胶表层由密度为0.9~1.0g/ml,粘度为8000~10000mpa•s的双组份液态硅胶混合物加热硫化得到,硫化后硅胶体的硬度为Shore 00 7±1度,抗撕裂强度≥3.0N/mm,弹性伸长率≥350%。
所述有机硅凝胶底层由添加轻质高分子微珠填充料后密度为0.5~0.7g/ml,粘度为7000~10000mpa•s的双组份液态硅胶混合物加热硫化得到,硫化后硅胶体的硬度为Shore 00 8~10度,抗撕裂强度≥3.0N/mm,弹性伸长率≥500%。
本发明还提供了上述无薄膜包覆透气型硅胶胸垫的制作方法,其特征在于:首先通过具有同一凹模和两个不同凸模的成型模具两次注射成型,依次成型所述的有机硅凝胶底层和有机硅凝胶表层,得到硅胶胸垫本体;然后再通过冲孔模具在所述硅胶胸垫本体上冲出透气孔。
其中,所述两个不同凸模包括成型所述有机硅凝胶底层的第一凸模和成型所述有机硅凝胶表层的第二凸模,所述第一凸模上具有用于在所述有机硅凝胶底层上表面成型花纹结构的凹槽或者凸起结构。
具体地,所述制作方法依次包括以下步骤:
①材料制备:采用无色透明的双组份液态有机硅橡胶,可选择地添加色浆调色后,混合得到密度为0.9~1.0g/ml,粘度为8000~10000mpa•s的硅胶混合物作为有机硅凝胶表层原料;采用双组份液态有机硅橡胶,添加轻质高分子微珠填充料后,混合得到密度为0.5~0.7g/ml,粘度为7000~10000mpa•s的硅胶混合物作为有机硅凝胶底层原料;
②成型:通过注射成型设备将步骤①得到的有机硅凝胶底层原料注入成型模具中进行加温硫化成型,得到有机硅凝胶底层;然后更换凸模,将步骤①得到的有机硅凝胶表层原料注入成型模具中,在所述有机硅凝胶底层上加温硫化成型所述有机硅凝胶表层,得到由有机硅凝胶底层和有机硅凝胶表层相结合的硅胶胸垫本体;
③修边:将步骤②得到的硅胶胸垫本体从模具中取出,进行整体修边处理,去除注射浇口处残留胶料;
④冲孔:采用冲床和冲孔模具对修边处理后的硅胶胸垫本体进行孔位穿刺,制作透气孔;
⑤表面处理:在冲孔后的硅胶胸垫本体的外表面涂覆手感硅油。
由于采用上述技术方案,本发明的无薄膜包覆硅胶胸垫具有重量更轻、更加透气,易于清洗且表层具有极高柔软度的优点,解决了现有技术中已有胸垫产品的典型缺陷,而且底层表面具有立体花纹结构的图案造型,外观更加美观新颖。本发明提供的制作方法工艺简单,成本较低,造型变化方便,易于形成系列化,适于大规模生产,应用前景广泛。

硅胶胸垫本体10的外表面涂覆有手感硅油。手感硅油可增加硅胶胸垫本体的表面爽滑度。
其中,所述有机硅凝胶表层由密度为0.9~1.0g/ml,粘度为8000~10000mpa•s的双组份液态硅胶混合物加热硫化得到,硫化后硅胶体的硬度为Shore 00 7±1度(根据美国材料与试验协会标准《ASTM D2240-05(2010)用硬度计测定橡胶硬度的标准测定方法》测定),抗撕裂强度≥3.0N/mm,弹性伸长率≥350%。该双组份液态硅胶混合物采用双组份液态无色透明有机硅橡胶,根据设计需要在两个组分中分别添加色浆进行调色搅拌后充分混合得到。
所述有机硅凝胶底层由添加轻质高分子微珠填充料后密度为0.5~0.7g/ml,粘度为7000~10000mpa•s的双组份液态硅胶混合物加热硫化得到,硫化后硅胶体的硬度为Shore 00 8~10度(根据美国材料与试验协会标准《ASTM D2240-05(2010)用硬度计测定橡胶硬度的标准测定方法》测定),抗撕裂强度≥3.0N/mm,弹性伸长率≥500%。其中,该双组份液态硅胶混合物的密度大小通过在两个组分中分别添加适量的轻质高分子微珠填充料进行调整。
本发明还提供了上述无薄膜包覆透气型硅胶胸垫的制作方法,首先通过具有同一凹模和两个不同凸模的成型模具两次注射成型,依次成型有机硅凝胶底层11和有机硅凝胶表层12,得到硅胶胸垫本体10;然后再通过冲孔模具在所述硅胶胸垫本体上冲出透气孔13。两个不同凸模包括成型所述有机硅凝胶底层的第一凸模和成型所述有机硅凝胶表层的第二凸模,所述第一凸模上具有用于在所述有机硅凝胶底层上表面成型花纹结构的凹槽或者凸起结构。

(二)成型:
通过注射成型设备将有机硅凝胶底层原料注入成型模具中进行加温硫化成型,得到有机硅凝胶底层11。其中,注射成型设备中需携带料桶内刮壁搅拌功能,以放置轻质高分子微珠填充料上浮,导致材料密度不均。通过凹模和第一凸模成型后,有机硅凝胶底层11的上表面具有凸起或者凹下的花纹结构。成型后的有机硅凝胶底层的性能指标需达到:硬度为Shore 00 8~10度,抗撕裂强度≥3.0N/mm,弹性伸长率≥500%。
然后,采用凹模负压吸附和顶杆顶出凸模的方式,保持凹模及其内的有机硅凝胶底层11不动,将第一凸模更换为第二凸模,再将有机硅凝胶表层原料注入成型模具中,在所述有机硅凝胶底层11上加温硫化成型所述有机硅凝胶表层12,得到由有机硅凝胶底层和有机硅凝胶表层相结合的硅胶胸垫本体10。成型后的有机硅凝胶表层的性能指标需达到:硬度为Shore 00 7±1度,抗撕裂强度≥3.0N/mm,弹性伸长率≥350%。
(三)修边:
将以上步骤得到的硅胶胸垫本体10从模具中取出,进行整体修边处理,去除注射浇口处残留胶料。
(四)冲孔:
采用冲床和冲孔模具对修边处理后的硅胶胸垫本体10进行孔位穿刺,在硅胶胸垫本体10的厚度方向上贯穿制作多个透气孔13,使硅胶胸垫本体10的大面积范围上都具有透气孔13。
(五)表面处理:
在冲孔后的硅胶胸垫本体10的外表面进行两次手感硅油喷涂处理,增加爽滑度。
采用本发明的制作方法制作得到的无薄膜包覆透气型硅胶胸垫,具有以下优点:
1、采用医用级无薄膜包覆弹性有机硅凝胶,由于摒弃了表层薄膜的影响,整体手感更柔然、舒适且具模拟人体乳房组织的优良质感。
2、由于采用了硅胶轻质化和硅胶胸垫本体大范围冲孔技术手段,产品整体重量较同等造型普通硅胶胸垫产品相比,重量下降350%以上;同时,产品整体透气性能有极大的提高。
3、由于本发明所采用的硅胶材料具有良好的理化性能,产品具有极佳的耐用性,且易于保存,并真正实现了随时清洗(日常洗涤),随时使用的功能要求,从根本上解决了以往胸垫产品由于不宜洗涤而存在的卫生安全隐患。
4、产品通过表面处理后解决一般硅胶表面发涩的现象,手感更为爽滑,容易插入文胸垫兜,便于日常使用。
5、由于双层结合过程中在底层的表面预设置了立体结构的图案造型,产品更美观。
6、本发明产品造型变化方便,便于形成系列化。
