The fabrics wide application is in each field in people's life, and the fabrics is when providing convenience for people's life, and various bacterium and virus also can propagate through the fabrics, can cause harm to the human body, consequently in order to create good house and operational environment, the fabrics that have antibiotic antiviral function more and more receives the favor in market. Graphene is used in textile materials in the market at present, and the patent CN201811602932.8 provides a preparation method of an antibacterial fabric based on graphene, but the antibacterial property of the fabric prepared by the method is not ideal. Because the textile can contact human skin, the softness and the wear resistance of the textile fabric influence the use experience.
Therefore, the development of the long-acting broad-spectrum antibacterial and antiviral composition which can be applied to textiles has important practical value and significance.
Disclosure of Invention
In order to solve the problems, the invention provides a long-acting broad-spectrum antibacterial antiviral composition, which comprises the following raw materials of 1-6% of nano material, 0.1-1% of alkyl benzene sulfonate, 1-2% of antiviral component, 0-2% of surfactant and the balance of alkane oil.
Preferably, the surfactant is a cationic surfactant.
Preferably, the cationic surfactant is at least one selected from the group consisting of amine salt compounds, quaternary ammonium salt compounds, and heterocyclic compounds.
Further preferably, the quaternary ammonium salt compound is at least one selected from dodecyl dimethyl betaine, octadecyl dimethyl benzyl ammonium chloride, octadecyl trimethyl ammonium bromide, hexadecyl trimethyl ammonium bromide and dodecyl trimethyl ammonium chloride.
Further preferably, the quaternary ammonium salt compound is dodecyl dimethyl betaine.
Preferably, the alkyl benzene sulphonate has an HLB value of from 9 to 12. Wherein, the HLB value is the hydrophilic-lipophilic balance value of the surfactant.
Further preferably, the weight ratio of the alkylbenzene sulfonate to the surfactant is (0.5-2): 1.
with the improvement of the quality of life, the fabric is not kept in shielding and heat preservation, and functional materials developed on the basis of textiles are gradually concerned. The textile fabric is composed of fibers, the porous structure and the characteristics of the high molecular polymer enable the textile fabric to become a hotbed to which microorganisms are attached, the textile fabric is easy to become a carrier for growth and reproduction of the microorganisms such as bacteria and fungi, and the textile fabric with antibacterial property can eliminate the adverse effect of the microorganisms and eliminate the harm of the textile fabric to human health. The invention discovers through practical researches that the antibacterial property of the fabric can be improved by adding the quaternary ammonium salt compound into the antibacterial and antiviral composition. The reason is that cations in the quaternary ammonium salt compound can be combined with the bacteria body through chemical bonds, and are gathered on the surface of the bacteria to generate a chamber barrier effect, so that the transfer process of cell membrane substances is hindered, the cell growth and metabolism balance is damaged, and the sterilization and bacteriostasis effects are achieved.
Although the quaternary ammonium salt compound can improve the antibacterial effect of the textile, the chemical property of the quaternary ammonium salt compound determines that the quaternary ammonium salt compound is easy to generate antagonistic action with an anionic surfactant, and the active ingredients lose effectiveness, so that the impregnated textile is rough and stiff. The invention discovers that when the quaternary ammonium salt compound is further selected to be dodecyl dimethyl amine ethyl lactone, the surfactant and the dodecyl dimethyl amine ethyl lactone are compatible, so that the friction resistance of relative movement of yarns is reduced, the bending rigidity of the textile is reduced, the softness of the textile is improved, and the antibacterial and antiviral composition improves the antibacterial effect of the textile and simultaneously improves the softness of the textile.
Preferably, the nano material comprises graphene and basic zinc carbonate.
More preferably, the weight ratio of the graphene to the basic zinc carbonate is (1-4.6): 1.
researches find that the nano material can be combined with textiles through unique surface effect, quantum effect and size effect, so that various functional requirements of the textiles are improved, graphene is a good choice for the nano material to be applied to textile finishing due to the unique two-dimensional conjugated structure, but the technical problem of realizing textile functionalization is that how to combine the graphene with organic macromolecules forming fibers as an inorganic material. According to the invention, through experimental researches, the compatibility of the graphene and the textile can be improved when the nano material is prepared by compounding basic zinc carbonate and the graphene, and the antibacterial property of the textile after the graphene is subjected to post-treatment is improved. It is further found that when graphene and basic zinc carbonate are compounded at 200-230 ℃, the obtained antibacterial and antiviral composition can still enable the textile to keep an antibacterial effect after being washed for many times, the supposition is that under the condition, inorganic metal carbonate can be further decomposed into metal oxide with antibacterial activity, the bonding capability of the active metal oxide and the graphene is poor when the active metal oxide and the graphene are directly mixed, and the basic metal oxide, specifically the basic carbonate, can be uniformly filled in a graphene gap structure to further inhibit the agglomeration of the graphene in textile fibers, so that the textile loaded with the graphene can damage a cell structure after contacting microorganisms in the air, and causes the metabolic disturbance of the microorganisms and then dies, thereby achieving the antibacterial effect.
The softness of the textile is obviously improved by adopting the combined action of the alkylbenzene sulfonate and the surfactant, but the defects of loose fabric fiber tissue and changeability after multiple times of washing are easily caused. The invention unexpectedly discovers that when the weight ratio of the graphene to the basic zinc carbonate is (1-4.6): 1, the anti-denaturation capability of the textile can be effectively improved, and the inorganic metal oxide, the alkylbenzene sulfonate and the surfactant are filled and intercalated in the graphene structure together under the condition, so that the inorganic metal oxide, the alkylbenzene sulfonate and the surfactant are uniformly dispersed and filled in the fiber structure, the shear hysteresis quantity in the fabric is inhibited, the textile keeps softness and simultaneously keeps a proper fiber-to-fiber interaction force, the anti-deformation capability of the fabric after infiltration is improved, and the fabric keeps good softness and simultaneously has good mechanical elasticity.
Further preferably, the alkylbenzene sulfonate is at least one selected from sodium dodecylbenzene sulfonate, potassium dodecylbenzene sulfonate, sodium tridecylbenzene sulfonate and sodium 4-tetradecylbenzene sulfonate.
Further preferably, the alkylbenzene sulfonate is sodium dodecylbenzene sulfonate.
Preferably, the alkane oil is mineral oil.
Further preferably, the alkane oil is white oil.
Further preferably, the white oil is at least one selected from the group consisting of No. 3 white oil, no. 5 white oil, no. 7 white oil, and No. 10 white oil.
Preferably, the weight ratio of the nano material to the alkylbenzene sulfonate is (7-15): 1.
it is further preferred that the mineral oil has a kinematic viscosity of 4 to 28mm 2 The test temperature was 40 ℃ per second.
The graphene acts on the textile to endow the textile with better antibacterial property and mechanical property, but the high surface activity of the graphene enables the graphene to be easily agglomerated, so that the antibacterial and antiviral composition cannot be stably stored for a long time. The invention is researched and found through a large number of experiments, when the solvent is mineral oil, the specific kinematic viscosity is 4-28mm 2 When the mineral oil is used for the preparation of the composite, the compatibility of organic and inorganic components in the composite can be greatly improved, the metal oxide and the organic straight-chain compound form effective steric hindrance in a graphite layer structure, the composite is endowed with proper flow resistance, and the agglomeration and sedimentation of nano materials in a system are inhibited, so that the improvement of the aggregation and sedimentation of the nano materials in the system is realizedStability of the antibacterial and antiviral composition. Further, the weight ratio of the nano material to the alkylbenzene sulfonate is (7-15): 1, the antibacterial and antiviral effects of the antibacterial and antiviral composition are improved, and the antibacterial and antiviral effects are speculated to be that the abundant saturated alkane and cycloalkane in the mineral oil promote the interaction of the inorganic nano material and the organic dispersing component, so that the sterilization component can fully permeate and be loaded in the textile, harmful components such as bacteria, fungi and viruses in the air can be effectively adsorbed, the normal physiological metabolic activity of the textile is interfered, and the antibacterial and antiviral effects are preserved for a long time and durably.
Preferably, the antiviral component includes at least one of zinc pyrithione, a tea extract, a phthalo blue derivative, a silver-doped oxide, and chitosan.
Preferably, the antiviral component is a tea extract.
Preferably, the tea extract is at least one selected from the group consisting of black tea extract, green tea extract, white tea extract, and black tea extract.
The antibacterial ability of existing textiles is more explored, but the antiviral ability is often overlooked. The invention discovers that the antibacterial and antiviral functions of the textile can be achieved by adding the tea extract into the composition. The reason is that the components such as tea polyphenol, theaflavin and the like in the tea extract can inhibit the fusion of viruses and targeted cells, and the synthesis path of substances necessary for the vital activities of bacteria and viruses is blocked, so that the growth, activity and propagation process of microorganisms is stopped, and the effect of protecting the health of human bodies in a broad spectrum manner is achieved. The invention further discovers that when the tea extract is at least one of black tea extract, green tea extract and white tea extract, the textile can be endowed with long-acting antibacterial and antiviral capabilities, and possibly a specific tea extract is rich in active ingredients, so that the binding capability of components such as graphene and the like and textile fibers can be improved, active groups are wrapped on the fibers inside the textile, and the textile fibers are denatured and inactivated after being contacted with pathogens, and can still maintain stable antibacterial and antiviral effects even after being washed for multiple times. Meanwhile, the binding force between the nano material and the textile in the composition is enhanced, the mechanical property of the textile after infiltration is durably optimized, more excellent flexibility and size stability can be kept, and the requirements of the textile in different occasions are met.
The second aspect of the invention provides a preparation method of the long-acting broad-spectrum antibacterial and antiviral composition, wherein graphene and basic zinc carbonate are mixed at the temperature of more than 200 ℃, and then are mixed with alkyl benzene sulfonate, an antiviral component, a surfactant and alkane oil to obtain the long-acting broad-spectrum antibacterial and antiviral composition.
