Problems solved by technology

However, the charge storage performance of the existing electret air filter materials is average. During the use and storage of the electret filter materials, due to the direct contact between the moisture and particles in the air and the electret materials, the surface of the electret materials The charge dissipation is accelerated, so that the electret effect decays faster, which eventually leads to unstable filtration efficiency of the filter material

preparation example Construction

[0027] The preparation method of a kind of antibacterial, mildew-proof and anti-virus melt-blown filter material provided by the present invention comprises the following steps:

[0028] S1. Prepare a melt-blown polypropylene masterbatch containing copper, silver and zinc ion antibacterial agents; the content of the melt-blown polypropylene masterbatch is 90 to 98 parts, and the content of copper, silver and zinc ion antibacterial agents is 1 to 8 parts.

[0029] S2. Melt-blown polypropylene masterbatch described in step S1 is melt-blown and spun to obtain a melt-blown polypropylene non-woven fabric;

[0030] S3. The melt-blown polypropylene nonwoven fabric described in step S2 is subjected to water electret treatment to obtain an antibacterial, mildew-proof, and anti-virus melt-blown filter material.

[0031] Metal antibacterial agents are divided into silver ion antibacterial agents, zinc ion antibacterial agents, copper ion antibacterial agents, iron ion antibacterial agent...

Embodiment 1

[0043] A preparation method of an antibacterial, mildew-proof and anti-virus melt-blown filter material, comprising the following steps:

[0044] S1. Mix and granulate 95 parts of melt-blown polypropylene resin and 5 parts of copper-silver-zinc ion antibacterial agent to prepare a melt-blown polypropylene masterbatch containing copper-silver-zinc ion antibacterial agent; in copper-silver-zinc ion antibacterial agent, zinc ion The mass content is 0.5%, the copper ion content is 0.5%, and the silver ion content is 0.6%;

[0045] S2. Meltblown polypropylene masterbatch described in step S1 is meltblown and spun, and the temperature of the meltblown air flow is 220° C. to obtain a meltblown polypropylene nonwoven fabric;

[0046] S3. Carry out water electret treatment to the melt-blown polypropylene nonwoven fabric described in step S2 (transport the prepared high-purity water to the fan-shaped nozzle by a high-pressure pump, and carry out spunlace injection to the melt-blown poly...

Embodiment 2

[0048] A kind of preparation method of antibacterial, mildew-proof and anti-virus melt-blown filter material, compared with embodiment 1, the difference is that step S1 comprises: 95 parts of melt-blown polypropylene resin and 5 parts of copper-silver-zinc ion antibacterial agent and 1 Parts of stearic acid are mixed and granulated to prepare melt-blown polypropylene masterbatches containing copper, silver and zinc ion antibacterial agents. Others are substantially the same as in Embodiment 4, and will not be repeated here.

Abstract

The invention provides an antibacterial, anti-mildew and anti-virus melt-blown filter material and a preparation method thereof, comprising: preparing a melt-blown polypropylene masterbatch containing copper, silver and zinc ion antibacterial agents, and then performing melt-blown spinning to obtain a melt-blown Polypropylene non-woven fabric; water electret treatment is carried out on the melt-blown polypropylene non-woven fabric to obtain antibacterial, mildew-proof and anti-virus melt-blown filter material. In the present invention, stearic acid is added to the melt-blown polypropylene masterbatch or stearic acid and zinc oxide are sprayed onto the surface of the melt-blown polypropylene non-woven fabric through the melt-blown air flow, and the high temperature of the melt-blown air flow is used to make stearic acid and zinc oxide Ion or zinc oxide reacts to obtain organic electret stearate, which improves the stability of electret charges; stearic acid also plays a role in melting and bonding to improve its strength, and finally obtains high-efficiency, low-resistance, antibacterial, mildew-resistant, and anti-fungal materials. Virus meltblown filter material.

Description

technical field [0001] The invention relates to the technical field of air filter materials, in particular to an antibacterial, anti-mildew, anti-virus melt-blown filter material and a preparation method thereof. Background technique [0002] With the progress of the times, people's requirements for environmental quality are getting higher and higher. However, the rapid economic development has aggravated the pollution of the environment, and the dust, chemicals, and harmful microorganisms in the air have had adverse effects on people's health. Therefore, effective control of harmful substances in the air is a major problem to be solved. [0003] Melt-blown nonwoven fabric is a randomly arranged fiber layer with a fiber diameter of 1-5 microns produced by melt-blown technology. The high specific surface area of ​​these fibers and the tiny pore size between fibers can effectively absorb and intercept tiny solid particles. Therefore, it is widely used in the fields of air fi...
