通过在传统清洁产品中引入硅藻土,优化表面活性剂、辅料种类和配比,制备了新型硅藻土基清洁剂,主要应用在织物和玻璃瓶方面,并探究清洁效果、互染性、标签和霉斑去除率等性能。硅藻土基织物清洁剂较优配方为硅藻土用量5%,AEO-9 15%,6501 5%,AEO-7 5%,硅酸钠0.3%、棕榈酸2%、柠檬酸钠3%;玻璃瓶清洁剂的较优配方为硅藻土用量5%,AEO-9 15%,6501 5%,AEO-7 5%,硅酸钠3.6%,硫酸钠1.5%,葡萄糖酸钠1.8%,氢氧化钠7.5%。所制备的清洁剂对炭黑、蛋白和皮脂污布的清洁白度差较优于市售普通清洁产品。在织物清洁方面,产品可实现被清洁织物的零互染;在玻璃清洁方面,温度在70 ℃时脱标率为100%;清洁剂用量为2%时,霉斑去除率达100%。硅藻土能用于配制不同清洁剂。
With the process of global economic integration and the development of people’s high-quality life, high-efficiency, energy-saving and multi-functional washing products are attracting more and more attention. Diatomite is a kind of biogenic siliceous sedimentary rock, mainly composed of the remains of ancient diatoms. It is loose, light, porous, water-absorbent, and strong in permeability, as well as has large specific surface area and chemically stable properties. In addition, the porous properties of diatomaceous earth can achieve functions such as humidity adjustment, dye adsorption and heavy metal ion removal. The paper introduced diatomite into traditional cleaning products, and through optimizing the types and proportions of surfactants and auxiliary materials, a new type of diatomaceous earth-based cleaning agent was prepared. Its cleaning effect and prevention of mutual dyeing, label and mildew removal and other multi-functional performance were explored. It shows that the auxiliary materials of diatomite-based cleaner need to be fine-tuned according to its different uses. Diatomite-based fabric cleaner consists of 5% diatomite, 15% AEO-9, 5% 6501, 5% AEO-7, 0.3% sodium silicate, 2% palmitic acid and 3% sodium citrate. Glass bottle cleaner comprises 5% diatomite, 15% AEO-9, 5% 6501, 5% AEO-7, 3.6% sodium silicate, 1.5% sodium sulfate, 1.8% sodium gluconate, and 7.5% sodium hydroxide. The prepared product has a good cleaning effect. In terms of fabric cleaning, the clean whiteness difference of the prepared cleaning agent on carbon black, protein and sebum stained cloth is 12.3, 3, 10.2, respectively, which are better than common cleaning products on the market, and the product can realize zero inter-dyeing of the cleaned fabric. In terms of glass cleaning, the clean whiteness difference of the prepared cleaning agent to carbon black, protein cloth is 11.26 and 4.19, respectively, which are better than common cleaning products on the market. When the temperature reaches 70 ℃, the adhesive layer on the back of the label can be effectively dissociated, and the effect is uniform. So that the label can be detached as a whole, thereby reducing secondary pollution. When the amount of cleaners is 2%, the mildew removal rate on the glass reaches 100%. The addition of diatomite improves the washing effect, dye removal and mildew removal. Diatomite can be used to formulate different cleaning agents.
