Description

长效型甲醛清除剂
技术领域
本发明涉及一种空气净化剂，具体涉及一种长效型甲醛清除剂。
背景技术
中国室内环境的主要污染源来自建筑、装饰和家具，甲醛、苯、氨气污染超标已经严重影响了人们的身体健康。主要可以分为装修污染以及家具污染两个方面。
在装修过程中使用的油漆及各种装修用的涂料、皮革、地毯等，这些材料造成的主要污染物是苯、甲苯、TVOC等，比如木工板，木材来自天然本身无毒，而是其加工时使用尿醛胶粘接，而形成甲醛的污染源，而装修中使用胶水的主要成分为甲醛，油漆还有大量刺鼻的苯。
家具所用的材料以及家具制作过程中所用的涂料、胶黏剂等产生的甲醛也成为了室内空气污染的主要污染物之一，而甲醛具有强烈的致癌和促癌作用。大量文献记载，甲醛对人体健康的影响主要表现在嗅觉异常、刺激、过敏、肺功能异常、肝功能异常和免疫功能异常等方面。因此，家具的选择以及过后的家具污染消除不容忽视。
时下清除室内空气残留污染物质的首先应该是活性炭。它具有物理吸附和化学吸附的双重特性，可以有选择地吸附空气中的各种有害物质，以达到消毒除臭的目的。但活性炭取自煤炭，限于国家对能源的保护以及其制备成本较高，不能大规模普及，因而得不到广泛使用。
发明内容
针对现有技术存在的上述不足，本发明所要解决的技术问题是提供一种长效型甲醛清除剂。
本发明的技术问题，是通过下述技术方案得以实现的：
一种长效型甲醛清除剂，由下述重量份的原料组成：椰油酰胺丙基甜菜碱0.1-0.5份、甲酰胺10-20份、氯化钠3-7份、过氧化脲素0.5-1.5份、茶多酚1-3份、分散剂0.1-0.5份、有机酸1-5份、水65-75份。
优选地，所述的分散剂为六偏磷酸钠、焦磷酸钠、三聚磷酸钠中一种或多种的混合物。
更优选地，所述的分散剂由六偏磷酸钠、焦磷酸钠、三聚磷酸钠混合而成，所述六偏磷酸钠、焦磷酸钠、三聚磷酸钠的质量比为(1-3)：(1-3)：(1-3)。
优选地，所述的有机酸为富马酸、酒石酸、柠檬酸中一种或多种的混合物。
更优选地，所述的有机酸由富马酸、酒石酸、柠檬酸混合而成，所述富马酸、酒石酸、柠檬酸的质量比为(1-3)：(1-3)：(1-3)。
本发明还提供了上述长效型甲醛清除剂的制备方法，将各原料加入水中搅拌混合均匀即得。
本发明的长效型甲醛清除剂，能够有效杀菌、迅速分解室内的甲醛等有害气体、吸附微小粉尘、除异味，大大提高了室内的空气质量，清除剂作用时间较长，减小用户的经济负担，有效地减少因忘记更换甲醛清除剂而导致室内甲醛含量超标对人体健康的危害。
