Abstract
本发明一种用于内墙涂料的负离子净味水性罩光面漆建筑材料装饰领域，具体涉及内墙涂料罩光面漆。其质量配比为：水24‑65份，防腐杀菌剂7‑15份，负氧离子30‑50份，成膜助剂20‑40份，乙二醇10‑20份，消泡剂3‑5份，罩光乳液300‑600份，缓蚀剂1‑2份，增稠剂3‑7份。本发明负离子净味水性罩光面漆能够有效地达到降低室内空气中的甲醛、VOC和粉尘含量，并杀灭细菌和祛除异味的效果，同时还能够获取有效的防护，进而提升内墙涂料涂层的耐磨性避免负离子涂层遭受磨损而降低净化空气的情况从而有效地弥补了现有技术中的不足。相关助剂的加入能促进高分子化合物塑性流动和弹性变形，改善聚结性和展色性，帮助形成良好的连续涂膜。对提高涂料涂膜的流平性、光泽度、丰满度功效显著，还可以改善面漆中颜料的均匀性及稳定性，促进漆膜的耐擦洗性能、冻融稳定性及机械强度。
Description
技术领域
本发明涉及建筑材料装饰领域，具体涉及到内墙涂料罩光面漆。
背景技术
室内甲醛污染主要来自于建筑和装饰材料，目前市面上80％以上的人造板材是由胶黏剂脲醛树脂或酚醛树脂胶粘合而成的，脲醛树脂会在水分、热、光、金属离子的作用下缓慢分解，持续不断的释放甲醛。用脲醛泡沫树脂做隔热材料的预制板、贴墙布、贴墙纸、化纤地毯、泡沫塑料、油漆和涂料等也向外界散发甲醛。释放量一般为3.35mg/m3。有时可高达13.4mg/m3。因此在室内装修后，板材中残留的以及胶黏剂中未参与反应的游离状甲醛会逐渐向周围环境释放，是造成甲醛长期污染的重要来源。甲醛对眼、鼻、喉的黏膜有强烈的刺激作用，最普遍的症状就是眼睛受刺激和头痛，严重的可引起过敏性皮炎和哮喘。由于甲醛可与蛋白质反应生成氮次甲基化合物而使细胞中的蛋白质凝固变性，因而可抑制细胞机能。此外，甲醛还能和空气中的离子性氯化物反应生成二氯甲基醚，而后者是一种致癌物质。甲醛可被室内表面材料吸附富集，当室内温度升高时又重新释放出来，加剧污染效应。
负氧离子具有极强的氧化和吸附作用，可以主动捕捉空气中的有害物质，除能够清除空气中的降尘、飘尘等有害物质外，还能够与空气中的甲醛、苯、 TVOC 等装修污染物质发生反应，将其分解为二氧化碳和水。此外，生态级空气负离子由于粒径小、活性高、迁移距离远，可以到达室内的各个角落，清除甲醛等化学挥发物无死角、无残留，是目前治理甲醛污染的最好方法。
现有的罩光面漆大部分是不能释放出负氧离子的，少部分使用了相关技术，其负氧离子释放量也较少，通常只有0-50个/cm3，无法满足人们的需求。
通过在内墙涂料表层涂抹本发明负离子净味罩光面漆，能够有效地达到降低室内空气中的甲醛、VOC和粉尘含量，并杀灭细菌和祛除异味的效果，同时还能够获取有效的防护，进而提升内墙涂料涂层的耐磨性避免负离子涂层遭受磨损而降低净化空气的情况从而有效地弥补了现有技术中的不足。相关助剂的加入能促进高分子化合物塑性流动和弹性变形，改善聚结性和展色性，帮助形成良好的连续涂膜。对提高涂料涂膜的流平性、光泽度、丰满度功效显著，还可以改善面漆中颜料的均匀性及稳定性，促进漆膜的耐擦洗性能、冻融稳定性及机械强度。
