Description

Antibacterial, purifying and humidifying diatom cloth
Technical Field
The invention relates to the field of non-woven fabrics, in particular to antibacterial, purifying and humidifying diatom cloth.
Background
The diatom material is used as a relatively environment-friendly coating and is widely used in recent years, and graphene, activated carbon, diatom shale or kieselguhr on the market generally have the defects of small specific surface area, insufficient adsorption force and the like, so that the prepared non-woven fabric is poor in antibacterial property and hygroscopicity.
Disclosure of Invention
The invention aims to provide an antibacterial, purifying and humidifying diatom cloth, which solves the problems in the background technology.
In order to achieve the above purpose, in one aspect, the invention provides an antibacterial, purifying and humidifying diatom cloth, which comprises the following raw materials: 30-50 parts of graphene, 10-30 parts of activated carbon, 80-110 parts of a diatom material, 5-10 parts of a catalyst, a pore-forming agent and cloth.
As a further improvement of the technical scheme, the diatom material is selected from one or two of kieselguhr and kieselguhr shale, and is used as a raw material of the kieselguhr cloth.
As a further improvement of the technical scheme, the catalyst is selected from one or a mixture of two of a photocatalyst and a dark catalyst, the photocatalyst can generate substances with strong oxidizing property under the irradiation of light and can be used for decomposing organic compounds, partial inorganic compounds, bacteria, viruses and the like, in daily life, the photocatalyst can effectively degrade toxic and harmful gases in the air such as formaldehyde and the like, efficiently purify the air, effectively kill various bacteria and decompose and harmlessly treat toxins released by the bacteria or fungi, the dark catalyst is made of a discharge material loaded catalytic material, and the dark catalyst can decompose harmful substances under the condition without the irradiation of light by utilizing the characteristic that the discharge material releases electrons.
As a further improvement of the technical scheme, the hole forming agent is selected from one or more of polyethylene glycol, polyurethane, polyvinylpyrrolidone and strong cellulose, and is used for forming holes in the diatom cloth, so that the specific surface area and the number of the holes are increased, the hole structure is improved, the adsorption capacity of the diatom cloth is stronger, and the air permeability of the diatom cloth is ensured.
As a further improvement of the technical solution, the fabric is selected from one of a non-woven fabric, a melt-blown fabric and a polyethylene film.
On the other hand, the invention provides a preparation process of the antibacterial purification and humidity-conditioning diatomite, which comprises any one of the antibacterial evolution and humidity-conditioning diatomite, and comprises the following operation steps:
s1, adding the graphene, the activated carbon and the diatom material into a reaction kettle, and stirring and mixing to obtain a mixture A;
s2, adding the pore-forming agent into the mixture A, heating, stirring and mixing to obtain a mixture B;

Comparative example 1 a diatomaceous cloth comprising:
preparation of granule A
Adding 40 parts of graphene, 20 parts of activated carbon and 95 parts of diatom material into a reaction kettle, and stirring and mixing to obtain a mixture A; adding the pore-forming agent into the mixture A, adding 12.5 parts of catalyst into the mixture A, stirring for 0.5-1h at the temperature of 60-80 ℃, and mixing to obtain a mixture B; and adding the mixture B into a dryer for drying at the drying temperature of 70-120 ℃ for 10-30min, and crushing to obtain particles A for later use.
Preparation of diatom cloth
Coating glue silk on one surface of the cloth, then uniformly laying the prepared particles A, and waiting for the glue silk to solidify; and bonding the other surface of the laid cloth with glue silk, and then cutting to obtain a finished product.
The antibacterial purifying and humidifying diatom cloth prepared by the invention has better antibacterial property and has a larger relation with a catalyst added into the diatom cloth, and in order to verify the related technical scheme, the applicant performs the following tests:
in comparative example 1, the prepared diatom cloth was tested for relevant indices using the method of example 3 with the catalyst removed, as shown in table 2:
TABLE 2
Figure BDA0003010613140000061
Figure BDA0003010613140000071
As shown in table 2, it can be seen from comparative example 1 and comparative example 3 that when the catalyst is removed, the bacteriostatic rate of the diatom cloth against each pathogen is reduced to below 85%, and the bacteriostatic rate is much lower than that of the diatom cloth prepared by the invention, so that it can be seen that the important factor for changing the antibacterial property of the diatom cloth is changed when the catalyst is added into the raw materials for preparing the diatom cloth.
The antibacterial, purifying and humidifying diatom cloth prepared by the invention has good moisture absorption performance and has a large relationship with a pore-making agent added into the diatom cloth, and in order to verify the related technical scheme, the applicant performs the following tests:
in comparative example 2, the method of example 3 is used to determine the indexes after the values of the specific surface area of the materials before and after the hole making of the diatom cloth are detected, which are specifically shown in table 3:
TABLE 3
Figure BDA0003010613140000072
It can be seen that the specific surface area of the material prepared by the pore-forming agent and the proportion of 20nm pores are greatly improved, but the pore volume is reduced because the pore-forming agent fills the occupied space in the original pores to cause the reduction of the pore volume.
Comparing the pore diagrams measured before and after the pore making of the diatomite shale, as shown in fig. 6 and 7, it can be seen from the graphs that a huge peak value of the pore diameter of the diatomite shale after the pore making is 6.65 times of the peak value before the pore making is not performed within the range of 3-5nm, and the research shows that the optimal pore diameter range of the porous material for humidifying and adsorbing ions and air materials is within the range of 1-7 nm, so that the adsorption performance and the humidifying performance of the material A after the pore making are greatly improved.
The prepared diatom is arranged in a humidity measuring instrument for detecting the moisture absorption and release performance of the diatom for 72 hours, and the prefix GZT of the modified diatom is shown in table 4:
TABLE 4
Figure BDA0003010613140000081
Therefore, the moisture absorbing and releasing capacity of the material (GZT) after hole forming is improved by 30-60%, and good effects are kept after 72-hour moisture absorbing and releasing experiments, so that the humidity adjusting capacity after hole forming is greatly improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
