具体实施方式detailed description

为使本发明实施例的目的、技术方案和优点更加清楚，下面将对本发明实施例中的技术方案进行清楚、完整地描述。实施例中未注明具体条件者，按照常规条件或制造商建议的条件进行。所用试剂或仪器未注明生产厂商者，均为可以通过市售购买获得的常规产品。The technical solutions in the embodiments of the present invention will be clearly and completely described below in order to clarify the objects, the technical solutions and the advantages of the embodiments of the present invention. Those who do not specify the specific conditions in the examples are carried out according to the conventional conditions or the conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are conventional products that can be obtained by commercially available purchase.

下面对本发明实施例的颗粒物阻隔材料及其在防雾霾中的应用进行具体说明。The particulate barrier material of the embodiment of the present invention and its application in anti-fog are specifically described below.

颗粒物阻隔材料是由阳离子聚合物作为溶质溶解于溶剂中形成的。其中，阳离子聚合物占颗粒物阻隔材料的质量百分比为0.1～10％。阳离子聚合物是指长链上有阳离子基团的聚合物，一般都指水溶性聚合物。阳离子聚合物可以是通过化学合成制备的，也可以是天然的高分子化合物如：多糖、淀粉、纤维素、壳聚糖经化学合成制备而得到的。本实施例中，溶剂为水，水选自去离子水、蒸馏水、超纯水中的一种或多种，优选去离子水。 The particulate barrier material is formed by dissolving a cationic polymer as a solute in a solvent. Wherein, the cationic polymer accounts for 0.1% to 10% by mass of the particulate barrier material. A cationic polymer refers to a polymer having a cationic group on a long chain, and generally refers to a water-soluble polymer. The cationic polymer may be prepared by chemical synthesis, or may be obtained by chemical synthesis of a natural polymer compound such as polysaccharide, starch, cellulose or chitosan. In this embodiment, the solvent is water, and the water is selected from one or more of deionized water, distilled water, and ultrapure water, preferably deionized water.

阳离子聚合物的质量百分比为0.1～10％，能够保证阳离子聚合物充分溶解于溶剂中，并且分布均匀，阳离子聚合物的质量百分比代表了100g颗粒物阻隔材料中含有阳离子聚合物的量，当阳离子聚合物的量越大时，阳离子聚合物对空气中的悬浮颗粒物的吸附能力逐渐增强，最终趋于稳定数值，但吸附力过强，易造成空气流通不顺，本实施例中选择阳离子聚合物的质量百分比为0.1～10％，不仅能够达到较佳的吸附过滤效果，同时还能保持空气流通顺畅。The cationic polymer has a mass percentage of 0.1 to 10%, which ensures that the cationic polymer is sufficiently dissolved in the solvent and has a uniform distribution. The mass percentage of the cationic polymer represents the amount of the cationic polymer contained in the 100 g of the particulate barrier material when cationic polymerization When the amount of the substance is larger, the adsorption capacity of the cationic polymer to the suspended particles in the air is gradually enhanced, and finally tends to be stable, but the adsorption force is too strong, and the air circulation is liable to be unsatisfactory. In this embodiment, the cationic polymer is selected. The mass percentage is 0.1 to 10%, which not only achieves better adsorption and filtration effects, but also maintains smooth air circulation.

阳离子聚合物由于其具有多种活泼的基团，可与许多物质亲和、吸附形成氢键。主要是絮凝带负电荷的胶体，阳离子聚合物具有除浊、脱色、吸附、粘合等功能。现有技术中，阳离子聚合物主要用于：沐浴液、洗面奶、洗发水、洗发香波，滋润沐浴露，护发素，焗油膏，洗手液等个人护理产品；用作水剂农药的增效剂；用作矿物浮选剂；用作高效阳离子乳化剂；与硅油、酯基季铵盐等复配用于织物柔软剂；用于造纸过程中的助流、助滤剂，树脂障碍控制剂；用于污水处理的絮凝助剂等领域。Due to its many reactive groups, cationic polymers can affinity with many substances and adsorb to form hydrogen bonds.

In the prior art, cationic polymers are mainly used for: personal care products such as body wash, facial cleanser, shampoo, shampoo, moisturizing shower gel, hair conditioner, ointment, hand soap, etc.; Used as a mineral flotation agent; as a high-efficiency cationic emulsifier; as a fabric softener in combination with silicone oil, ester quaternary ammonium salt, etc.; flow aid, filter aid, resin barrier control in papermaking process Agent; in the field of flocculation aids for sewage treatment.

本实施例将阳离子聚合物作为溶质溶解于溶剂中形成颗粒物阻隔材料，由于该颗粒物阻隔材料内带有阳离子，带电荷的颗粒物阻隔材料能够形成微电保护层，空气中的带有正电荷的悬浮颗粒物质与阳离子聚合物相互排斥，从而起到阻止悬浮颗粒物通过的作用，同时空气中带有负电荷的悬浮颗粒物质与阳离子聚合物相互吸引，从而凝聚为较大的颗粒而沉降，不再被人体吸入。 In this embodiment, a cationic polymer is dissolved as a solute in a solvent to form a particulate barrier material. Since the particulate barrier material has a cation therein, the charged particulate barrier material can form a micro-electric protective layer and a positively charged suspension in the air. The particulate matter and the cationic polymer repel each other to prevent the passage of suspended particles, and the suspended particulate matter with negative charge in the air attracts the cationic polymer, thereby agglomerating into larger particles and sinking, no longer being Inhalation by the human body.

本实施例中阳离子聚合物占颗粒物阻隔材料的质量百分比为0.1～10％。其中，阳离子聚合物的种类有多种，本实施例中，优选阳离子聚合物包括聚季铵盐、阳离子烷基多糖苷、高分子阳离子烷基多糖苷、阳离子聚丙烯酰胺、阳离子瓜尔胶、阳离子淀粉、阳离子玉米淀粉、阳离子蛋白肽中的至少一种。更优选地，阳离子聚合物包括聚季铵盐、高分子阳离子烷基多糖苷、阳离子聚丙烯酰胺中的至少一种。In the present embodiment, the cationic polymer accounts for 0.1 to 10% by mass of the particulate barrier material.

The polymer cation alkyl polyglycoside has a molecular weight of 8000 to 12000, and the polymer cationic alkyl polyglycoside is used as a particulate blocking material made of a cationic polymer, and has a high cationic charge density, and has a better effect of blocking particles. At the same time, its foaming power is strong, and the particulate matter barrier material is sprayed on the face or cloth for easy cleaning.

Of course, in other embodiments, the substituent may further include a hydroxyalkyl group. For example: hydroxyethyl, hydroxymethyl, and the like.

阳离子聚丙烯酰胺(CPAM)是线型高分子化合物，由于它具有多种活泼的基团，可与许多物质亲和、吸附形成氢键，从而使空气中的悬浮颗粒物质被吸附，有效的阻隔颗粒物被吸入。Cationic polyacrylamide (CPAM) is a linear polymer compound. Because it has a variety of active groups, it can affinity with many substances and adsorb to form hydrogen bonds, so that suspended particulate matter in the air is adsorbed and effectively blocked.
