Description

一种负离子PVC地板及其制备方法
技术领域
本发明涉及一种PVC地板及制备,尤其是涉及一种负离子PVC地板及其制备方法。
背景技术
随着时代发展日新月异,曝露的环境问题日益严重,因此生产对环境及人们健康有益的建材产品迎合大众需求顺应了时代的趋势,具有广阔的市场前景。
PVC地板也称为“轻体地材”,又称塑料地板,是一种新型轻体地面装饰材料。是一种在欧美及亚洲的日韩广受欢迎的产品,并已逐步引入中国市场,使用非常广泛,比如家庭、医院、学校、办公楼、工厂、公共场所、超市、商业等各种场所。PVC地板指采用聚氯乙烯材料生产的地板,具体就是以聚氯乙烯及其共聚树脂为主要原料,加入填料、增塑剂、稳定剂、着色剂等辅料,在片状连续基材上,经涂敷工艺或经压延、挤出或挤压工艺生产而成。
负离子粉,是人类利用自然界产生负离子的原理,人工合成或者配比的一种复合矿物,其中稀土就占到了60%以上,电气石粉占约20%,以及复合其他矿物。负离子对人体有益,已为国内外医学界专家通过临床实践所验证,不仅能促使成人体合成和储存维生素,能强化和激活人体的生理活动,被称为“空气维生素”。
将负离子粉与PVC地板的生产结合在一起,将会对地板建材的应用上起到一个质的提升,目前有一些专利也对负离子地板进行了一定的研究,但是或多或少还存在一些问题。
如中国专利CN104629209负离子地板,该专利通过添加负离子添加剂到地板中去实现释放负离子的效果,但该地板的不具备良好的防静电性能;
再如中国专利CN106088525一种负离子实木复合地板,该专利将负离子粉混入胶黏剂中用于实木复合地板的制备,并非是应用于PVC地板,且实木地板价格昂贵,尺寸稳定性差,而且该工艺流程较复杂。
因此,一种能有效解决上述问题的负离子PVC地板的研究及其制备值得探讨。
发明内容
发明目的:为了解决现有技术中所存在的问题,本发明提出了一种与PVC地板兼容性佳,有效释放负离子,有益人类居住环境的净化的负离子PVC地板及其制备方法。

(2)压机:将作为最上层的耐磨层的透明片、作为装饰层的彩膜、分别根据面层和底层配方制备的底片按顺序进行叠料,按照工艺参数进入热压与冷压,热压时间控制在28-34min;压力保持3.5-7mpa,冷压时间控制在26-33min,形成半成品;
(3)UV热处理:半成品静置24h后进入UV热处理,收料温度控制在20-33℃;
(4)冲切开槽:将半成品按照要求冲切成规定尺寸及扣型;
(5)包装:成品打包。
有益效果:本发明提供的一种负离子PVC地板及其制备方法,针对现有负离子PVC地板存在的缺陷,以5%-10%的质量比用负离子粉替代传统配方中的石粉,并辅以环氧大豆油、增塑剂,钙稳定剂,锌稳定剂几种助剂最佳配比的协同作用,通过底片生产、压机、UV热处理、静置冲切开槽包装的工艺流程制备出一种能够有效释放出负离子的PVC地板,有效降低甲醛的释放量,同时地板具有较佳的耐磨耐污以及防滑性能,质感佳,可广泛应用于家庭、医院、学校、办公楼、工厂、公共场所、超市、商业等各种场所,给空气净化产业带来了很大的推动作用,有益人类健康和环境发展。
