Description

一种天然乳胶发泡床垫的制备方法
技术领域
本申请属于床垫材料领域,尤其涉及一种天然乳胶发泡床垫的制备方法。
背景技术
床垫是为了保证消费者获得健康而又舒适的睡眠而使用的一种介于人体和床之间的物品,床垫材质繁多,不同材料制作的床垫能给人带来不同的睡眠效果。
1881年,美国德克萨斯州休斯敦郊外一个小镇,一位名叫Daniel Haynes的扎棉机工匠开始了一种棉塞床垫的生产。
人生的三分之一是在睡眠中度过的,衡量人们是否拥有“健康睡眠”的四大标志是:睡眠充分,时间足,质量好,效率高;入睡容易;睡眠连续,不会中断;睡眠深适,醒来倦意全消等。睡眠质量的好坏与床垫息息相关,消费者在选择床垫时可从床垫的通透性、减压性、支撑度、服贴性、床面张力、睡眠温度和睡眠湿度等方面来选购类型合适、品质优良的床垫。由于每个人的具体情况不同,比如体重、身高、胖瘦以及个人生活习惯、喜好等,人们在选购床垫时应根据自身的具体情况和当地的气候和个人的经济收入条件综合考虑予以选择。其中最基本的要求是仰卧时能保持腰椎生理前凸,身体曲线正常;侧卧时以不使腰椎弯曲、侧弯为主。
1900年,美.西蒙斯,袋装弹簧床垫,二十世纪初,丹洛甫,橡胶发泡软垫,1932年,意大利,马里奥·贝里纪,以聚氨基甲酸泡沫用于垫子,第二次世界大战时,德国,路易斯·考拉尼,还设计了一种椭圆形床垫,并按人体躺在床垫上不同部位的体压,分成软、中、硬的三个部分,使人体骨骼保持最佳状态,国外还出现了一种“主动回应弹簧系统”,改变了以往惯用的弹簧构造形式,使人更加舒适,弹性持久不变;有些弹簧床垫还与聚酯发泡结合,软硬度可随人选择。
棕榈床垫由天然乳胶编制而成,一般质地较硬,或硬中稍带软。该床垫价格相对较低。使用时有天然棕榈气味,耐用程度差,易塌陷变形,承托性能差,保养不好易虫蛀或发霉等。
儿童床垫是指专门为青少年儿童生长发育特点而研发的床垫,与普通床垫的最大区别就是让床垫适应青少年儿童骨骼成长的需求,从而有效预防驼背等青少年儿童常见问题。
儿童床垫据2006年8月30日国际骨骼健康发展基金会历经10年对欧、美、亚三地各1000万人群的调查统计。欧洲、美洲、亚洲(主要指中国)成年人群的驼背比例1\1.223\3.1726;18岁前未成年人比例1\1.164\1.557,这两组比例倒不是说中国人驼背比例高都是由床垫所导致的,但可以说是息息相关的。
除了工作、生活、身体、心理等方面的原因外,拥有“卫生、舒适、美观、耐用”的健康寝具是获得高质量睡眠的关键所在。
随着物质文明和技术工艺的不断进步,现代人们使用的床垫种类逐渐趋向多元化,主要有:弹簧床垫、棕榈床垫、乳胶床垫、水床垫、气床垫、磁床垫等,在这些床垫中,弹簧床垫占较大的比重。
