Problems solved by technology

People's awareness of travel health and family daily health protection is gradually increasing, and the market for related purification products such as masks and air purification continues to expand. The HEPA filter layer mentioned in patent CN201110236989.2 and another melt-blown non-woven fabric mentioned in patent CN94111475 , which are two common filter materials in the market at present, but these two materials use electret material as the filter layer, which will significantly reduce the filtration efficiency when it encounters water, and cannot be cleaned and reused
At the same time, during the use of these two filter materials, bacterial growth is common, resulting in secondary pollution.

Embodiment 1

[0045] The preparation method of multifunctional antibacterial anti-haze self-cleaning macromolecule nanocomposite material, the bamboo fiber non-woven fabric described in table 1 is as base material, the antibacterial agent of certain quality is weighed and cold catalyst and binding agent are mixed according to a certain ratio , using printing and dyeing technology to form an antibacterial self-cleaning polymer composite material, and then form a nanofibrous web through a spinning process on either side of the antibacterial self-cleaning polymer composite material surface to form an antibacterial and anti-haze self-cleaning polymer nanocomposite material. The material contains 0.1mg / m 2 Antimicrobial agent, 0.1 g / m 2 Cold catalyst and 0.1g / m 2 The nanofiber membrane can provide antibacterial effect, anti-smog effect and self-cleaning effect.

Embodiment 2

[0047] The preparation method of multifunctional antibacterial and haze-proof self-cleaning macromolecule nanocomposite material, the cotton fiber non-woven fabric described in Table 1 is used as base material, and the antibacterial agent of certain quality is weighed and mixed with cold catalyst and binder according to a certain ratio , using printing and dyeing technology to form an antibacterial self-cleaning polymer composite material, and then form a nanofibrous web through a spinning process on either side of the antibacterial self-cleaning polymer composite material surface to form an antibacterial and anti-haze self-cleaning polymer nanocomposite material. Material contains 5mg / m 2 Antimicrobial agent, 1 g / m 2 Cold catalyst and 1g / m 2 The nanofiber membrane can provide antibacterial effect, anti-smog effect and self-cleaning effect.

Embodiment 3

[0049] The preparation method of multifunctional antibacterial and haze-proof self-cleaning macromolecule nanocomposite material, the polyethylene terephthalate non-woven fabric described in table 1 is used as base material, takes certain quality antibacterial agent and cold catalyst and bonding The agent is mixed according to a certain ratio, and the printing and dyeing technology is used to form an antibacterial self-cleaning polymer composite material, and then the surface of the antibacterial self-cleaning polymer composite material is thermally fused with the nanofiber net to form an antibacterial and anti-haze self-cleaning polymer nanocomposite material. The composite contains 200mg / m 2 Antibacterial agent, 20g / m 2 Cold catalyst and 50g / m 2 The nanofiber membrane can provide antibacterial effect, anti-smog effect and self-cleaning effect.

Abstract

The invention provides a multifunctional antibacterial haze-prevention self-cleaning macromolecule nano composite material and application thereof. The multifunctional antibacterial haze-prevention self-cleaning macromolecule nano composite material comprises 1) a 0.1mg / m<2>-200mg / m<2> organic photocatalysis additive and a 0.1mg / m<2>-20g / m<2> cold catalyst metal oxide so as to provide a macromolecule material with the antibacterial and self-cleaning efficacies, and with the function of framework support; and 2) a 0.1g / m<2>-50g / m<2> nano fiber layer so as to provide the functions of filtering and self-cleaning. The multifunctional macromolecule nano composite material can effectively kill pathogenic bacteria, can filter PM2.5 particulate matter, can remove peculiar smell and has a self-cleaning function simultaneously, can be cleaned, and is applicable to domestic appliances with relevant need, air purification, water purification and industrial filtering application.

Description

technical field [0001] The invention relates to a new type of environment-friendly material for home use, office work, and public medical care, and in particular to a multifunctional antibacterial, haze-proof, and self-cleaning polymer nanocomposite material and its application. Background technique [0002] With the development of industrial economy, the environmental pollution caused by industrial production is becoming more and more serious, and people's living space is facing great challenges. People's awareness of travel health and family daily health protection is gradually increasing, and the market for related purification products such as masks and air purification continues to expand. The HEPA filter layer mentioned in patent CN201110236989.2 and another melt-blown non-woven fabric mentioned in patent CN94111475 , These are two common filter materials currently on the market, but these two materials use electret materials as the filter layer, which will significant...
