Description
技术领域technical field
本发明涉及一种新材料，具体涉及一种空气净化剂。The invention relates to a new material, in particular to an air purifier.
背景技术Background technique
随着人们对室内环境空气质量的越来越重视，各类空气净化剂也应运而生。目前市面上出现的空气净化剂很多，总体可分为以下3种类型：吸附性空气净化剂、遮盖型除味产品、分解型除味产品。吸附性空气净化剂主要利用类似于活性炭等物质的物理吸附、化学吸附、氧化、催化氧化和还原等性能去除空气中污染物。遮盖型空气净化剂是利用具有香味的挥发性物质将有异味的物质进行遮盖。分解型空气净化剂一般光照条件下能够产生具有较强氧化还原能力的羟基自由基或超氧自由基，从而将空气中有害物质进行氧化分解。As people pay more and more attention to the air quality of indoor environment, various air purifiers have emerged as the times require. At present, there are many air purifiers on the market, which can be generally divided into the following three types: adsorptive air purifiers, masking deodorizing products, and decomposing deodorizing products. Adsorptive air purifiers mainly use physical adsorption, chemical adsorption, oxidation, catalytic oxidation and reduction properties similar to activated carbon to remove pollutants in the air. Covering-type air purifiers use volatile substances with fragrance to cover odorous substances. Decomposing air purifiers can generate hydroxyl radicals or superoxide radicals with strong redox ability under general light conditions, so as to oxidize and decompose harmful substances in the air.
这些产品的出现从某种程度上迎合了人们的需求，各生产商、经销商也趁机对其效果大肆宣扬，正面效果的鼓吹远远超过了实际效能，使得一些劣质产品也登上了空气净化治理的舞台，部分产品对空气中的杂志和水进行过滤后，空气中仍残留较多的杂志和水，同时还加入芳香族或者单萜类化合物，其具有一定的毒副作用。鉴于此，需要研制出净化效果更好的、综合性能更好的空气净化剂解决目前空气污染等问题。The emergence of these products caters to people’s needs to a certain extent, and various manufacturers and distributors also took the opportunity to publicize their effects. The advocacy of positive effects far exceeds the actual performance, making some inferior products also boarded the air purification industry. In the stage of treatment, after some products filter the magazines and water in the air, there are still more magazines and water in the air, and at the same time, aromatic or monoterpene compounds are added, which have certain toxic and side effects. In view of this, it is necessary to develop an air purifier with better purification effect and better comprehensive performance to solve the current problems such as air pollution.

复合型空气净化剂性能评价实验Composite air purifier performance evaluation experiment
评价方法：在1m³的密闭空间内，注入一定体积的某工厂排出废气，静置24h后测试密闭空间内气体浓度为初始浓度。将实施例1~9与对比例1~8制备的复合型空气净化剂放入该密闭空间，72h后测试密闭空间内气体浓度，计算清除率。清除率=（初始浓度-试样浓度）/初始浓度×100%。测试结果见下表。Evaluation method: Inject a certain volume of exhaust gas from a certain factory into a confined space of 1m³, and after standing for 24 hours, test the gas concentration in the confined space as the initial concentration. Put the composite air purifiers prepared in Examples 1-9 and Comparative Examples 1-8 into the confined space, test the gas concentration in the confined space after 72 hours, and calculate the clearance rate. Clearance rate = (initial concentration - sample concentration) / initial concentration × 100%. The test results are shown in the table below.
复合型空气净化剂性能评价结果Composite air purifier performance evaluation results
由上表可知，采用实施例1的重量份数制备的高效复合型空气净化剂甲醛清除率达到98.4%，氨清除率达99.2%，TVOC清除率98.9%，其能去除室内空气中的污染物和各种有害杂质，有效改善空气质量。实施例1制备的高效复合型空气净化剂甲醛清除率、氨清除率和TVOC清除率均比对比例1、对比例2要高，可能的原因是本发明中特制的硫化锌-SBA-15纳米体不仅具有物理吸附和化学吸附双重特性，且其表面官能团的含量和表面活性位点大幅增加，对有毒气体的吸附效率较高，同时加入的纳米银、二氧化钛均具有良好的抗菌、杀菌及分解有害气体的功能，三种材料相互协同可大幅提高复合型空气净化剂净化空气的综合性能。另外对比例3~8说明该制备硫化锌-SBA-15纳米体时原料、原料比例选择，纳米银、二氧化钛、硫化锌-SBA-15纳米体的配比对其净化性能影响较大。As can be seen from the above table, the high-efficiency composite air purifier prepared by the parts by weight of Example 1 has a formaldehyde removal rate of 98.4%, an ammonia removal rate of 99.2%, and a TVOC removal rate of 98.9%, which can remove pollutants in the indoor air and various harmful impurities, effectively improving air quality. The high-efficiency composite air purifier prepared in Example 1 has higher formaldehyde scavenging rate, ammonia scavenging rate and TVOC scavenging rate than Comparative Example 1 and Comparative Example 2. The possible reason is that the special zinc sulfide-SBA-15 nanometer The body not only has the dual characteristics of physical adsorption and chemical adsorption, but also has a substantial increase in the content of surface functional groups and surface active sites, and has a high adsorption efficiency for toxic gases. At the same time, the added nano silver and titanium dioxide have good antibacterial, bactericidal and decomposition The function of harmful gases, the synergy of the three materials can greatly improve the comprehensive performance of the composite air purifier for air purification. In addition, comparative examples 3 to 8 illustrate that the selection of raw materials and raw material ratios for the preparation of zinc sulfide-SBA-15 nano-body, and the ratio of nano-silver, titanium dioxide, and zinc sulfide-SBA-15 nano-body have a great influence on its purification performance.
