Description

Technical Field

[0001] This utility model relates to the field of filter cotton technology, and in particular to a high-adsorption air filter cotton. Background Technology

[0002] Air filter cotton, also known as air cotton filter, is mainly used to filter dust particles in the air. Air filter cotton is categorized by material, including non-woven fabric, synthetic fiber filter cotton, glass fiber filter cotton, activated carbon filter cotton, and high-temperature synthetic fiber filter cotton. Air filter cotton is an environmentally friendly product used for filtering and purifying air. The term "filter cotton" generally refers to air filtration.

[0003] Air filter cotton is a filter material specifically designed to intercept and adsorb dust particles in the air. Its main function is to effectively remove particulate matter, pollutants, or harmful substances through physical interception and chemical adsorption, thereby purifying and improving the air. Air filter cotton is typically made of synthetic fibers (such as polyester), glass fiber, non-woven fabric, or activated carbon, and has high porosity, air and water permeability, and a certain degree of corrosion resistance. These characteristics make air filter cotton perform excellently in air purification systems, effectively removing particulate matter, pollutants, and harmful substances.

[0004] Existing air filter cotton has the following defects in actual use:

[0005] Traditional air filter cotton (such as meltblown, needle-punched, spunbond nonwoven fabrics, etc.) mainly relies on physical interception (such as sieving, inertial impaction, diffusion) to remove particulate matter (PM2.5, PM10, dust, etc.) from the air. However, their ability to remove gaseous pollutants (VOCs, formaldehyde, ozone, odor molecules, etc.) is very limited. Utility Model Content

[0006] In view of the technical problem that traditional air filter cottons (such as meltblown, needle-punched, spunbond nonwoven fabrics, etc.) mainly rely on physical interception (such as sieving, inertial impaction, diffusion) to remove particulate matter (PM2.5, PM10, dust, etc.) from the air, but their ability to remove gaseous pollutants (VOCs, formaldehyde, ozone, odor molecules, etc.) is very limited, this utility model provides an air filter cotton with high adsorption capacity.

[0007] The technical solution adopted by this utility model is: a high-strength adsorption air filter cotton, including a filter cotton body, the filter cotton body including a filter structure and a glass fiber mesh cloth, the glass fiber mesh cloth being disposed on one side of the filter structure, the filter structure including a first protection mechanism, a reinforcing mechanism, an adsorption mechanism and a second protection mechanism, the first protection mechanism, the reinforcing mechanism, the adsorption mechanism and the second protection mechanism being sequentially bonded together by an adhesive.

[0008] Furthermore, the adsorption mechanism includes an activated carbon adsorption layer, a nanoporous adsorption layer, and a functionalized fiber layer.

[0009] Furthermore, the nanoporous adsorption layer is disposed on one side of the activated carbon adsorption layer, and the functionalized fiber layer is disposed on one side of the nanoporous adsorption layer.

[0010] Furthermore, the first protective mechanism includes a first substrate layer and an antioxidant layer, wherein the antioxidant layer is disposed on one side of the first substrate layer.

[0011] Furthermore, the reinforcing mechanism includes an antistatic layer and a flame-retardant layer, with the flame-retardant layer disposed on one side of the antistatic layer and the antistatic layer disposed on one side of the antioxidant layer.

[0012] Furthermore, the second protective mechanism includes an antibacterial layer and a second substrate layer, wherein the antibacterial layer is disposed on one side of the functionalized fiber layer and the second substrate layer is disposed on one side of the antibacterial layer.

[0013] The beneficial effects of this utility model are:

[0014] This invention uses a porous fiber material as the matrix for its filter structure and incorporates an activated carbon adsorption layer, a nanoporous adsorption layer, and a functionalized fiber layer. This improves the adsorption capacity and rate for gaseous pollutants while ensuring good particulate matter interception efficiency, thus solving the problem of poor gaseous pollutant removal capacity of traditional filter cotton.

[0015] Secondly, by strengthening the mechanism and the fiberglass mesh, this utility model can prevent the filter cotton body from being disturbed by external static electricity, reduce the flammability of the filter cotton body in a dry environment, and provide reinforcement to the filter cotton body, thereby providing effective protection for the filter cotton body during use.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a high-strength adsorption air filter cotton.

[0024] The specific technical solution includes a filter cotton body 1, which includes a filter structure 2 and a fiberglass mesh 3. The fiberglass mesh 3 is disposed on one side of the filter structure 2. The filter structure 2 includes a first protective mechanism 4, a reinforcing mechanism 5, an adsorption mechanism 6, and a second protective mechanism 7. The first protective mechanism 4, the reinforcing mechanism 5, the adsorption mechanism 6, and the second protective mechanism 7 are sequentially bonded together with an adhesive. The fiberglass mesh 3 is bonded to the air outlet surface of the filter structure 2 to provide reinforcement for the filter cotton body 1. The first protective mechanism 4 is the air inlet surface, and the second protective mechanism 7 is the air outlet surface. The reinforcing mechanism 5 and the adsorption mechanism 6 are located in the first protective mechanism 4 and the second protective mechanism 7 as the core layer. The four layers are stacked and then hot-rolled together to form a whole.

[0025] Reference Figure 3 As shown, the adsorption mechanism 6 includes an activated carbon adsorption layer 601, a nanoporous adsorption layer 602, and a functionalized fiber layer 603. The nanoporous adsorption layer 602 is disposed on one side of the activated carbon adsorption layer 601, and the functionalized fiber layer 603 is disposed on one side of the nanoporous adsorption layer 602. The first protective mechanism 4 includes a first substrate layer 401 and an antioxidant layer 402. The antioxidant layer 402 is disposed on one side of the first substrate layer 401. The reinforcing mechanism 5 includes an antistatic layer 501 and a flame-retardant layer 502. The flame-retardant layer 502 is disposed on one side of the antistatic layer 501. Layer 501 is disposed on one side of the antioxidant layer 402. The second protective mechanism 7 includes an antibacterial layer 701 and a second substrate layer 702.

Both the first substrate layer 401 of the first protective mechanism 4 and the second substrate layer 702 of the second protective mechanism 7 are porous nonwoven fabric structures formed from cellulose fibers through processes such as meltblowing, spunbonding, needle punching, and hydroentangling, providing a basic filter framework and mechanical support. The antioxidant layer 402 is an anti-oxidation coating, applied by coating... The anti-oxidation layer 402 is firmly bonded to the surface of the first substrate layer 401, preventing oxidation inside the filter cotton body 1. The antibacterial layer 701 is a nano-silver antibacterial coating, firmly bonded to the surface of the second substrate layer 702 through coating, improving the purification effect of the filter cotton body 1 on harmful substances. The antistatic layer 501 and flame-retardant layer 502 are made of silver fiber with antistatic function and polytetrafluoroethylene fiber with flame-retardant function, preventing the filter cotton body 1 from being affected by external static electricity and reducing the static electricity of the filter cotton body 1. In cases where flammability occurs in a dry environment, the activated carbon adsorption layer 601 is made of activated carbon fibers that are anchored inside the fiber network by a deep impregnation process of a slurry made of modified coconut shell activated carbon powder combined with an adhesive. The activated carbon fibers are then made into a needle-punched nonwoven fabric, which is modified by oxidation or ammoniation. The nanoporous adsorption layer 602 is a porous nano-alumina coating that is firmly bonded to one side of the activated carbon adsorption layer 601 by coating. The functionalized fiber layer 603 is a needle-punched nonwoven fabric made of PP fibers containing 30% activated carbon masterbatch.
