Abstract
The utility model discloses formaldehyde-removing framework non-woven fabric which comprises a pet framework layer, an active carbon filter layer and a pp filter layer; a formaldehyde purification adsorbent is arranged in the pet framework layer; the pp filter layer is arranged on the pet framework layer; the activated carbon filter layer is disposed between the pp filter layer and the pet skeleton layer; the pp filter layer has a surface coated with an amino resin layer. The formaldehyde adsorption composite material not only provides strength and support for the composite material, but also has a formaldehyde adsorption function, and greatly improves the pollutant carrying capacity of the formaldehyde adsorption efficiency under the condition of not interfering the gas adsorption capacity of the carbon-sandwiched layer.
Description
Technical Field
The utility model belongs to the technical field of non-woven fabric filter materials, and particularly relates to a formaldehyde-removing framework non-woven fabric.
Background
The traditional non-woven fabric is removed and adsorbed with formaldehyde by carbon cloth, but the framework layer only provides the function of supporting and shaping to provide strength, and the traditional short fiber framework has a considerable technical blank in the aspects of participating in the filtration efficiency and additional adding function.
SUMMERY OF THE UTILITY MODEL
The utility model provides the formaldehyde-removing framework non-woven fabric for solving the technical problems.
The solution adopted by the utility model for realizing the technical effect is as follows:
the formaldehyde removing framework non-woven fabric comprises a pet framework layer, an active carbon filter layer and a pp filter layer; a formaldehyde purification adsorbent is arranged in the pet framework layer; the pp filtration layer is disposed on the pet scaffold layer; the activated carbon filter layer is disposed between the pp filter layer and the pet skeleton layer; the pp filter layer has a surface coated with an amino resin layer.
Preferably, the formaldehyde purification adsorbent is an active silicon bag.
Preferably, terylene spunbonded non-woven fabric layers are arranged between the activated carbon filter layer and the pet framework as well as between the activated carbon filter layer and the pp filter layer.
The utility model has the beneficial effects that: aiming at the defect that the traditional short fiber framework non-woven fabric only provides strength and support for the composite material but has no other functions, the formaldehyde adsorption function is transferred to the framework short fiber framework layer, so that the pollutant carrying capacity of the formaldehyde adsorption efficiency is greatly improved, and meanwhile, the gas adsorption capacity of the carbon-sandwiched layer is not interfered.
Drawings
FIG. 1 is a schematic cross-sectional view of a formaldehyde-removing skeleton nonwoven fabric disclosed in the embodiment of the present invention.
And (3) identification and explanation: 1-pet skeleton layer, 2-activated carbon filter layer, 3-pp filter layer, 4-formaldehyde purification adsorbent, 5-amino resin layer, and 6-terylene spunbonded non-woven fabric layer.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model. It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When one element is referred to as being "fixedly attached" to another element, it can be fixedly attached by welding, bolting, gluing, or the like.
Referring to fig. 1, in the preferred embodiment of the present invention, a formaldehyde removing skeleton nonwoven fabric is disclosed, which comprises a pet skeleton layer 1, an activated carbon filter layer 2 and a pp filter layer 3; a formaldehyde purification adsorbent 4 is arranged in the pet framework layer 1; the pp filter layer 3 is disposed on the pet skeleton layer 1; the activated carbon filter layer 2 is disposed between the pp filter layer 3 and the pet skeleton layer 1; the pp filter layer 3 is coated on its surface with an amino resin layer 5.
Specifically, the formaldehyde purification adsorbent 4 is an active silicon bag.
Specifically, terylene spunbonded non-woven fabric layers 6 are arranged between the activated carbon filter layer 2 and the pet skeleton 1 and between the activated carbon filter layer 2 and the pp filter layer 3. Furthermore, the terylene spunbonded nonwoven fabric layer 6 is provided with a plurality of filtering holes which mainly play a role in supporting and strengthening the strength without affecting the filtering.
From the above description, the present invention not only provides strength and support for the composite material, but also has formaldehyde adsorption function, and greatly improves the pollutant carrying capacity of formaldehyde adsorption efficiency without interfering with the gas adsorption capacity of the carbon-sandwiched layer.
While the preferred embodiments of the present invention have been illustrated in detail in the accompanying drawings, it should be understood that the scope of the utility model includes, but is not limited to, the embodiments described above; while the utility model has been described with reference to specific embodiments, it will be appreciated by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
