Description
本发明属于材料技术领域，尤其涉及一种乳凝胶复合材料及其制备方法。
贴身衣物如女士内衣通常设置有模杯。目前，市场上用于贴身衣物的模杯材料一般为海绵或硅胶。海绵具有蜂巢式结构，其组织严密、不易透气，水分子容易储存于蜂巢内，因此，以海绵作为模杯材料的贴身衣物容易产生闷热感；同时，海绵的蜂巢式结构容易藏污纳垢，成为细菌生长的温床，不利于人体健康。此外，海绵文胸手感较为粗糙，舒适度不高。而以硅胶作为模杯材料的贴身衣物不仅质量重，而且不透气，长时间穿着会引起皮肤过敏、红肿、发白等不良现象。
炎炎夏日，室内外温度升高，人体感觉极为不适，尤其是穿戴采用海绵、硅胶作为模杯材料的贴身衣物时，更让人产生闷热感。因此，开发一种可以让人感觉清凉、抗菌、透气的新型模杯材质，显得尤为重要。
本发明实施例提供了一种乳凝胶复合材料及其制备方法，以解决现有用于的模杯材料不透气、闷热的问题。

将所述水凝胶粉末、所述复合乳胶中除发泡剂以外的组分进行混合处理后，得到混合物料；
在所述混合物料中加入发泡剂进行发泡处理，制备乳凝胶复合材料。
本发明实施例提供的乳凝胶复合材料，同时含有水凝胶粉末和复合乳胶，且所述水凝胶粉末的重量含量为所述复合乳胶重量的3%-15%。由此得到的乳凝胶复合材料，能快速均衡分散人体热量，有效保持恒温效果，且乳凝胶复合材料光滑不刺激皮肤，使穿戴者柔软舒适。相较于未添加水凝胶粉末的复合乳胶产品，本发明提供的乳凝胶复合材料，撕裂度提高5-15%，回弹性提高7-20%，变形率小4-12%。将本发明提供的乳凝胶复合材料经高温热压定型，应用于贴身衣物模杯上，具有清爽的优点，可以提高穿戴者的舒适度适，尤其适用于炎热的夏季使用。
本发明提供的乳凝胶复合材料，只需要在复合乳胶发泡前加入水凝胶粉末，然后经发泡处理即可制备。方法简单易于控制，具有较好的规模化生产空间。
