Description

凝胶垫及其紫外固化生产方法
技术领域
本发明涉及一种凝胶垫及其紫外固化生产方法。
背景技术 说
近年来， 市场上出现了一些凝胶垫等相应的凉垫产品， 如申请号：
200810063081. 4, 但是却存在凉爽时间不够长， 凉爽感觉不是非常明显的问题， 此外， 在生产该产品时， 存在产品表面产生较长 "凹痕"； 容易将内容物溅到外 包材料上面而引起产品表面脏污； 如果封口时袋中的空气没有排挤完全， 产品表 面会产生许多大小不一的 "凹坑"， 从而影响外观； 生产过程需要热压从而耗能 较多； 产品生产出来后需要降温后才能包装从而产生工艺繁琐、工厂占地面积大 等缺陷。 '
书
此外， 这些方法在生产过程中， 要么加热固化需要时间长， 能源损耗大， 效率也不高， 如申请号： 200810063081. 4， 有的方法能源损耗会小一些， 但固化 时间需要 5小时以上， 严重影响效率和厂地运作； 此外， 一些使用高分子交联成 形的凝胶垫会出现强度不够， 胶体使用寿命不长， 易变形， 固含量不够等特别严 重的影响产品使用的缺陷。
