【摘要】：室内环境质量直接影响着人体健康,因此室内空气污染已被美国环保局(EPA)列为第四大环境健康危害。世界环卫组织研究结果显示:人类由于环境恶化所导致的疾病越来越多,室内空气污染也受到世界卫生组织的密切关注,被列为人类健康的十大威胁之一。随着人们对居住环境要求越来越高,室内装饰材料所含的大量污染物质也越来越受到人们的关注。论文系统研究了除醛丙烯酸酯乳液的分子设计、制备与涂膜性能。以此乳液为涂料基体,通过配方设计,采用TiO2光催化改性硅藻土、沸石及硅胶、海藻泥长效吸收并降解甲醛、甲苯及氨的耐污渍内墙乳胶漆,采用多种方法有效协同吸附环境中存在的甲醛、甲苯及氨,并与之发生不可逆反应。另外在兼顾除甲醛特性的同时,选取了性能更为优异的耐沾污型乳液和填料,使得涂膜具有优异的耐沾污性能。针对祛甲醛、甲苯、氨和耐污渍的关键技术问题,将TiO2改性硅藻土、沸石及硅胶、海藻泥,耐沾污技术复合使用,以上述乳液为涂料基体,对颜填料和助剂等进行筛选,进行了配方优化,制备了功能型内墙乳胶漆,结果表明:以此材料制备的海藻泥功能型内墙乳胶漆对于室内甲醛的48小时内的甲醛净化效率高达90.1%,甲醛净化效果持久性达80.2%;室内甲苯的48小时内的甲苯净化效率高达51.1%,甲苯净化效果持久性达42.2%;室内氨的48小时内的净化效率高达46.9%,氨净化效果持久性达42.7%,耐沾污分数达到8.8分。经过系统的研究开发,以本工作为基础由嘉宝莉公司推动上市的“海藻泥”内墙乳胶漆,漆膜可以长效吸收并分解甲醛、甲苯及氨。目前市场上同类产品极少,与其它空气污染治理技术相比,此产品具有显著优点。自从本项目产品上市以后,在全国各地获得了一致好评,也在涂料行业掀起了一次环保净化的新高潮。
[Abstract]:Indoor environmental quality has a direct impact on human health, so indoor air pollution has been ranked as the fourth largest environmental health hazard by EPA (EPA). The results of the World Sanitation Organization show that more and more diseases are caused by the deterioration of the environment, and the indoor air pollution has been paid close attention to by the World Health Organization, and it has been listed as one of the ten threats to human health. With the increasing demands on the living environment, people pay more and more attention to a large number of pollutants contained in interior decoration materials. The molecular design, preparation and film properties of aldehyde-removing acrylate emulsion were systematically studied in this paper. The emulsion was used as the coating matrix, and the TiO2 photocatalytic modification of diatomite, zeolite and silica gel was used to absorb and degrade formaldehyde, toluene and ammonia for a long time. Formaldehyde, toluene and ammonia in the environment were effectively adsorbed by various methods and irreversibly reacted with them. In addition, the anti-fouling emulsion and fillers with better performance were selected while taking into account the characteristics of formaldehyde removal, which made the coating have excellent contamination resistance. In view of the key technical problems of removing formaldehyde, toluene, ammonia and stain resistance, the TiO2 modified diatomite, zeolite and silica gel, seaweed mud and stain resistant technology were combined, and the above emulsion was used as the coating matrix to screen the pigments, fillers and auxiliaries, etc. The formula was optimized and the functional inner wall latex paint was prepared. The results showed that the efficiency of formaldehyde purification was 90.1% and 80.2% in 48 hours of indoor formaldehyde, and the purification efficiency of toluene was 80.2% in 48 hours of indoor toluene. The purification efficiency of indoor ammonia is up to 46.9% in 48 hours, the persistence of ammonia purification effect is 42.7%, and the contamination resistance fraction is 8.8%. The efficiency of purification of toluene is up to 42.2%, the purification efficiency of indoor ammonia is up to 46.9% within 48 hours of ammonia purification, and the efficiency of ammonia purification is 42.7%. Through systematic research and development, based on this work, the "seaweed mud" inner wall latex paint, which is promoted by Jiapoli Company, can be absorbed and decomposed into formaldehyde, toluene and ammonia for a long time. At present, there are few similar products in the market. Compared with other air pollution control technology, this product has remarkable advantages. Since the products of the project went on the market, it has been well received all over the country, and has also set off a new high tide of environmental protection purification in the paint industry.
