Problems solved by technology

Conventional air filter materials can only remove particulate matter in the air, but cannot remove bioaerosols such as bacteria, viruses, molds and pollen in the air, and cannot remove VOC
Conventional air filter materials cannot meet people's requirements for indoor air quality. It has become a current research hotspot to develop a functional air filter material that can kill bacteria, viruses and VOC in the air while removing particulate matter.

preparation example 1

[0112] Take the following weight materials to prepare functional emulsion:

[0113] Microcapsule phase change material (PCM): 200g,

[0114] Nano ZnO: 10% by weight of PCM,

[0115] Water: add up to 1000ml.

[0116] The microcapsule phase change material was purchased from Hong Kong Nano Sports Tech. Company, the model is TRC-05-01, and the phase change temperature of the phase change material is 28°C. Wherein the microcapsule phase change material is the weight of solid matter. Add PCM to an appropriate amount of water, add ZnO (MN6Z, Zhejiang Hongsheng Material Technology Co., Ltd.) under slow stirring, and stir at room temperature for 2.5 hours to obtain the functional emulsion of the present invention.

[0119] Microcapsule phase change material (PCM): 400g,

[0120] Nano ZnO: 0.5% by weight of PCM,

[0121] Adhesive LT 200g

[0122] Water: add up to 1000ml.

[0123] The microcapsule phase change material was purchased from Hong Kong Nano Sports Tech. Company, the model is TRC-05-01, and the phase change temperature of the phase change material is 28°C. Wherein the microcapsule phase change material is the weight of solid matter. Add PCM to an appropriate amount of water, add ZnO under slow stirring, and stir at room temperature for 2.5 hours to obtain the functional emulsion of the present invention.

preparation example 3

[0125] Take the following weight materials to prepare functional emulsion:

[0126] Microencapsulated phase change material (PCM): 5g,

[0127] Nano-TiO 2: 30% of PCM weight,

[0128] KC softener (produced by Shanghai Auxiliary Factory) 25g,

[0129] Synthetic styrene-butadiene emulsion 180g,

[0130] Water: add up to 1000ml.

[0131] Among them, the microcapsule phase change material was purchased from Hong Kong Nano Sports Tech. Company, the model is TRC-05-01A. Wherein the microcapsule phase change material is the weight of solid matter. Add PCM to an appropriate amount of water, and add nano-TiO while stirring slowly 2 (SCI-nanometer titanium dioxide, Shanghai Zhuerna High-tech Powder Material Co., Ltd.), stirred at room temperature for 2.5 hours to obtain the functional emulsion of the present invention.

Abstract

The invention provides a kin of function latex for adjusting temperature and purifying air, comprising microcapsule phase-change material, nm photocatalysis material and liquid medium. The invention also provides a preparation method of the function latex and composite air filtering material using the function latex and preparation method of the composite air filtering material. The composite air filtering material has good effects such as adjusting temperature, purifying air, antibiosis, and removing volatile and harmful gas.

Description

technical field [0001] The present invention relates to a functional emulsion capable of regulating temperature and purifying air, especially a functional emulsion containing nano photocatalytic material and microcapsule phase change material. The present invention also relates to the preparation method of said functional emulsion and the Composite air filter material. Background technique [0002] In the mid-1970s, the outbreak of the energy crisis forced countries all over the world to seriously pay attention to the research of energy-saving technologies. In developed countries, building energy consumption accounts for more than 30% to 40% of total energy consumption, so countries attach great importance to the research of building energy-saving technologies. In order to meet the requirements of energy saving, the airtightness of the building has been greatly strengthened, and the fresh air volume has also been reduced, which greatly increases the concentration of indoor ...
