Description

一种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。
由于受到压迫而造成血液循环阻塞,会促使人体苍老,而床垫太软会使人体重量得不到平衡的支持而留下弯腰驼背等后遗症。因此,一张好的床垫是人们保护脊椎最迫切的需要。
在购买床垫时不要光看花色或者价格,要选择信誉卓著的品牌,这样可以确保售后的相关服务;其实最重要的就是床垫本身的质量还有使用床垫的人群。这样才能使你所选购的床垫质量和舒适度得到保证。
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。
乳胶床垫又分合成乳胶和天然乳胶,合成乳胶来源于石油,弹性和透气不足,天然乳胶来源于橡胶树。天然乳胶散发淡淡的乳香味,更加亲近自然,柔软舒适,透气良好,且乳胶中的橡树蛋白能抑制病菌及过敏原潜伏,但成本很高。
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。
