Description
Technical Field
The invention belongs to the field of materials, and particularly relates to a diionic composite antibacterial and dust-deposition-preventing material, and an application and a preparation method thereof.
Background
For products such as air conditioning fans, consumers are more concerned about the cleanliness and health of indoor air during the use of air conditioners. Meanwhile, with the rise of living standard, young people gradually become the dominant force of air conditioner consumption, and higher requirements are provided for air quality and air health in the using process of the air conditioner.
Indoor unit cross-flow fan is AS the air conditioner indoor air conditioning air supply source, mainly adds glass reinforcing for the AS material at present and makes, produces the dust easily and piles up in long-term use, and then the phenomenon that breed and go mildy of bacterium appear at the fan blade, leads to the air conditioner to blow out the wind to have the peculiar smell, seriously influences the cleanness and the health of indoor air, uses probably to cause respiratory disease to take place for a long time. And the cross-flow fan is positioned in the air conditioner, so that a user is not easy to disassemble and clean, and the traditional self-cleaning method only can be carried out on the heat exchanger and cannot clean the fan. Therefore, the application of the anti-bacterial technology to the cross-flow fan reduces the bacterial growth and the mildew of the fan and improves the air health in the use of the air conditioner.
The Ag + antibacterial agent mainly used in the current antibacterial product can be directly Ag + release type, and can be Ag + loaded to carriers such as molecular sieve, phosphate and the like, slow release type, AgO type, nano silver and the like. However, silver ions are aged under the conditions of illumination and the like, so that the color of the product becomes dark, the antibacterial performance is reduced, and the antibacterial weather resistance and the antibacterial long-acting performance are limited to a certain extent. In addition, the existing antibacterial fan is mainly added in a coating form, and has the following problems: 1. because the limited color of the coating agent is relatively single, the individual selection cannot be carried out; 2. special equipment and tooling are required for supporting, so that the cost is relatively high; 3. the antibacterial coating only stays on the surface of the fan material, the antibacterial effect of the uncovered area of the coating is poor, and the antibacterial durability is limited.
Therefore, the antibacterial materials used for products such as cross-flow fans of indoor units of air conditioners are required to be further improved.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, one purpose of the invention is to provide a dual-ion composite antibacterial and anti-dust material, and an application and a preparation method thereof, wherein the dual-ion composite antibacterial and anti-dust material has good mechanical properties, ideal antibacterial and mildew-proof properties and an anti-dust advantage, can be directly used for preparing blades of a cross-flow fan of an indoor unit of an air conditioner, further eliminates the use defects of the existing antibacterial coating, remarkably improves the production efficiency of the blades, reduces the production cost and improves the antibacterial durability.
According to one aspect of the invention, the invention provides a dual-ion composite antibacterial and anti-dust-deposition material for a cross-flow fan of an indoor unit of an air conditioner, which comprises the following components in part by weight: 60-90 parts by weight of a plastic base material; 0.1-3 parts by weight of a silver-zinc composite antibacterial agent; 0.4-0.8 weight parts of organic antibacterial agent; 1-35 parts by weight of a long-acting antistatic agent; 1-6 parts by weight of a dispersant; 10 to 35 parts by weight of an inorganic filler and 0.1 to 1 part by weight of an antioxidant.
Therefore, the double-ion composite antibacterial and anti-dust-deposition material adopts the silver-zinc double ions as effective antibacterial active ingredients, so that the aim of better synergistic antibacterial effect is achieved on one hand, and on the other hand, the stability of the antibacterial effect of the silver ions can be effectively improved by adding the zinc ions, and the problems of darkening of the color of a product and reduction of the antibacterial effect caused by reduction and oxidation of the silver ions in the using process are solved. In addition, the long-acting antistatic agent can effectively reduce the dust accumulation on the surface of the fan blade caused by static electricity, so that the cleanliness of the fan blade is improved, and the bacterial breeding can be avoided.

Detailed Description
The following detailed description of embodiments of the invention is intended to be illustrative, and is not to be construed as limiting the invention.
According to one aspect of the invention, the invention provides a dual-ion composite antibacterial and anti-dust-deposition material for a cross-flow fan of an indoor unit of an air conditioner, which comprises the following components in part by weight: 60-90 parts by weight of a plastic base material; 0.1-3 parts by weight of a silver-zinc composite antibacterial agent; 0.4-0.8 weight parts of organic antibacterial agent; 1-6 parts by weight of a dispersant; 10-35 parts by weight of an inorganic filler; 0.1 to 1 part by weight of an antioxidant; and 1-35 parts by weight of a long-acting antistatic agent.
Therefore, the double-ion composite antibacterial and anti-dust-deposition material adopts the silver-zinc double ions as effective antibacterial active ingredients, so that the aim of better synergistic antibacterial effect is achieved on one hand, and on the other hand, the stability of the antibacterial effect of the silver ions can be effectively improved by adding the zinc ions, and the problems of darkening of the color of a product and reduction of the antibacterial effect caused by reduction and oxidation of the silver ions in the using process are solved. In addition, the long-acting antistatic agent can effectively reduce the dust accumulation on the surface of the fan blade caused by static electricity, so that the cleanliness of the fan blade is improved, and the bacterial breeding can be avoided.
More importantly, the final material has good mechanical property and antibacterial, antiseptic and antistatic properties by optimizing the proportion of the components. The dual-ion composite antibacterial and dust-deposition-preventing material can be directly used for preparing the fan blades of the cross-flow fan of the indoor unit of the air conditioner, so that an antibacterial coating is completely replaced, the use defect of the antibacterial coating is thoroughly eliminated, the production efficiency of the fan blades is obviously improved, and the production cost is reduced; and the integral fan blade is made of antibacterial and antistatic materials, so that the antibacterial durability can be obviously improved, and the service life can be prolonged.
The following describes the dual-ion composite antibacterial anti-dust material according to the embodiment of the present invention.
According to the above-mentioned embodiments of the present invention, the plastic substrate can be an AS (acrylonitrile-styrene resin). And the plastic base material is used as the base material, and the dosage of the plastic base material can be 60-90 parts by weight, so that the basic mechanical properties of the material, such as rigidity, hardness, toughness and the like, can be ensured. According to the specific embodiment of the invention, the usage amount of the plastic base material is preferably 60-80 parts by weight, so that the material can better meet the mechanical performance requirements of the cross-flow fan blade of the indoor unit of the air conditioner by matching with other components.
According to a specific embodiment of the present invention, the silver-zinc composite antibacterial agent is an antibacterial agent formed by loading silver ions and zinc ions on zeolite, water-soluble glass or calcium phosphate. Therefore, the antibacterial effect can be further improved by using the silver ions and the zinc ions together, the stability of the antibacterial effect of the silver ions can be effectively improved by using the zinc ions, and the situations that the color of a product is darkened and the antibacterial effect is reduced due to reduction and oxidation in the use process of the silver ions are reduced.
According to a specific embodiment of the present invention, the silver-zinc composite antibacterial agent is an antibacterial agent formed by loading silver ions and zinc ions on water-soluble glass. The silver-zinc composite antibacterial agent prepared by using the water-soluble glass as the carrier has high transparency and stable and long-acting ion release rate, so that the stability of the antibacterial effect can be further improved. Meanwhile, the method has the characteristic of low addition ratio, and is favorable for reducing the reduction of mechanical property of the fan material caused by the addition of the antibacterial agent.
According to the specific embodiment of the invention, the mass ratio of the silver ions to the zinc ions in the silver-zinc composite antibacterial agent is 1: (0.1-100). The inventor finds that the mechanical and thermal properties of the fan material can be better maintained while the better antibacterial effect is ensured by adopting the preferable proportion. The inventors have also found that if the amount of zinc ions is too large relative to the amount of silver ions, the antibacterial effect of the fan material is greatly reduced. On the contrary, if the amount of zinc ions is too small relative to silver ions, the synergistic effect of zinc ions and silver ions is reduced, silver ions are easily reduced and re-oxidized, the fan product is easily darkened, and the discoloration resistance and durability are somewhat reduced. Therefore, according to a specific example of the present invention, the mass ratio of silver ions to zinc ions is preferably 1: (2 to 30) may be, for example, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:16, 1:17, 1:18, 1:19, 1:20, 1:21, 1:22, 1:23, 1:24, 1:25, 1:26, 1:27, 1:28, 1:29, or 1: 30.
According to the specific embodiment of the invention, a certain content of organic antibacterial agent is added into the dual-ion composite antibacterial and dust-deposition-preventing material, so that the dual-ion composite antibacterial and dust-deposition-preventing material can achieve a synergistic antibacterial and mildew-preventing effect with the silver-zinc composite antibacterial agent, further the antibacterial effect is more durable, and the limitation of poor antibacterial durability of the existing antibacterial coating is effectively overcome. Specifically, the organic antibacterial agent may be at least one selected from SLM-04, quaternary ammonium salt antibacterial mildewcide, and biguanide antibacterial mildewcide. Thus, the mildew-proof performance can be further improved, and the inventor finds that the mechanical performance influence of the organic antibacterial agent on the material can be minimized. According to the specific embodiment of the invention, the amount of the organic antibacterial agent is 0.4-0.8 part by weight, so that the diionic composite antibacterial and dust-deposition-preventing material has a certain antibacterial effect and a certain mildew-proof effect by adding a proper amount of the organic antibacterial agent, and the antibacterial durability of the diionic composite antibacterial and dust-deposition-preventing material can be further remarkably improved. According to specific embodiments of the present invention, the organic antimicrobial agent may be preferably used in an amount of 0.5 to 0.7 parts by weight, for example, 0.5 parts by weight, 0.6 parts by weight, or 0.7 parts by weight.
According to some embodiments of the present invention, a certain amount of a long-acting antistatic agent is added to the above-mentioned dual-ion composite antibacterial and anti-dust-deposition material. And further, the dust accumulation on the surface of the fan blade caused by static electricity can be effectively reduced, so that the bacterial breeding is avoided. According to a specific embodiment of the present invention, the long-acting antistatic agent may specifically be at least one selected from the group consisting of antistatic agents TM, octadecyl diethanolamine, PEG, methyl acrylate, polyethylene oxide, and polyether ester amide. According to an embodiment of the present invention, the long-acting antistatic agent may be added in an amount of 1 to 35 parts by weight. The preferable addition amount can be 10-20 parts by weight, and by adopting the preferable addition amount, both the antistatic performance and the mechanical property of the modified material can be achieved. For example, the inventors have found that when the addition amount of the long-acting antistatic agent is too low, the material has poor anti-dust performance, whereas when the addition amount of the long-acting antistatic agent is too high, the mechanical properties of the material are easily reduced, and the material is easily subjected to fracture deformation. Therefore, the amount of the long-acting antistatic agent used is very important as an important component for modification and additional functions.
According to an embodiment of the present invention, the dispersant in the above formulation may be at least one selected from the group consisting of CH-10S, ST-278, polyethylene wax and stearic acid. This can further improve the dispersibility of the respective components, so that the respective components can be sufficiently mixed in the preparation process. Specifically, the dispersant may be used in an amount of 1 to 6 parts by weight. The amount of the dispersing agent is not too small or too much, if the amount is too small, the dispersing effect is not good, the antibacterial powder is in an aggregation state, and if the amount is too large, the aggregation phenomenon occurs again. The concentration of the dispersant used should comply with a dynamic equilibrium according to the actual situation. When the external conditions are changed, the equilibrium is broken and the nanoparticles agglomerate. When H in the dispersant and SiO in the antibacterial agent carrier2When the-OH of (A) is re-reacted to form a new surface chemical film, a new balance is reached so as to realize good dispersion. According to an embodiment of the present invention, the dispersant may be preferably used in an amount of 1 to 2%, for example, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, or 2.0%.
According to a specific embodiment of the present invention, the inorganic filler contained in the above formulation may be long glass fibers, which have been previously treated with a silane coupling agent. Thereby further improving the impact toughness, strength and hardness of the material. According to the specific embodiment of the invention, the usage amount of the long glass fiber can be 10-35 parts by weight, and since the antibacterial agent contained in the dual-ion composite antibacterial and dust-deposition-preventing material disclosed by the invention has influence on the mechanical property of the material, the influence can be effectively avoided by optimizing the usage amount of the long glass fiber, so that the dual-ion composite antibacterial and dust-deposition-preventing material has good mechanical property and also has better antibacterial and mildew-proof properties and dust-deposition-preventing properties. According to a specific example of the present invention, the long glass fiber may be preferably used in an amount of 15 to 30 parts by weight, for example, 15 parts by weight, 16 parts by weight, 174 parts by weight, 18 parts by weight, 19 parts by weight, 20 parts by weight, 21 parts by weight, 22 parts by weight, 23 parts by weight, 24 parts by weight, 25 parts by weight, 26 parts by weight, 27 parts by weight, 28 parts by weight, 29 parts by weight, or 30 parts by weight.
According to a specific embodiment of the invention, the dual-ion composite antibacterial and dust-deposition-preventing material further comprises 0.1-1 part by weight of an antioxidant, and the antioxidant is added to mainly prevent the material from being oxidized and degraded due to high temperature in the preparation process. Specifically, the antioxidant may be at least one selected from the group consisting of antioxidant 1010, antioxidant 168, and antioxidant 618. Thereby preventing the improvement of the antioxidant effect of the material during the preparation process.
According to the specific embodiment of the invention, the diionic composite antibacterial and dust-deposition-preventing material with the components and the proportion of the embodiment of the invention not only has good mechanical property, but also has better antibacterial and mildew-proof properties and dust-deposition-preventing properties. The dual-ion composite antibacterial dust-deposition-preventing material is tested under the conditions of a 2.75J pendulum and an A-type milling notch according to the requirements of GB/T1843, and the impact strength of the notch of the cantilever beam is measured to be more than 5.5kJ/m2(ii) a According to GB/T1040The test is carried out under the test condition of 50mm/min, the tensile strength is more than 105Mpa, and the elongation at break is more than 4.0%; the method is carried out according to the requirement of GB/T1634, and the heat distortion temperature is more than 95 ℃ when the test pressure is 1.80 MPa. In addition, the mildew-proof grade of the dual-ion composite antibacterial dust-deposition-preventing material can reach 0-1 grade, and the sterilization rate is not lower than 99 percent; the dust deposition prevention effect is reduced by more than 30 percent compared with the dust deposition amount of the common fan. Therefore, the composite antibacterial material can meet the requirement on the mechanical strength of the fan blade, and can be used for preparing the fan blade of the cross-flow fan of the indoor unit of the air conditioner, so that the fan blade has the advantages of antibiosis, mildew resistance and dust accumulation resistance. Therefore, the antibacterial coating is more convenient to use than the antibacterial coating, special equipment for the coating is not required for supporting, and the cost can be obviously saved compared with the antibacterial coating. In addition, the fan blade integrally has antibacterial mildew resistance and dust deposition resistance, the defect of incomplete coverage of an antibacterial coating can be overcome, the integral antibacterial mildew resistance is more durable, and the service life of the fan blade can be obviously prolonged.
According to another aspect of the invention, the invention further provides a fan, and according to an embodiment of the invention, fan blades of the fan are prepared from the dual-ion composite antibacterial and dust-deposition-preventing material described in the previous embodiment. From this, the fan flabellum that adopts the compound antibiotic deposition prevention material of dual ion to directly prepare not only has good mechanical properties, still has good antibiotic mould proof nature and deposition prevention advantage, and then can avoid piling up the phenomenon that breeds and go mildy of appearance bacterium because of the dust, and then effectively improve the clean health of air in the fan use, effectively avoid the fan to blow off the peculiar smell wind, seriously influence the indoor air quality, but also can avoid long-term use to arouse respiratory disease's possibility.

The fan prepared in comparative example 2 mainly has the defect of poor mechanical performance, and analysis is mainly that the mechanical performance of the fan product is poor due to the fact that the proportion of the material is too small because the plastic base material is used too little and the antibacterial, mildewproof and oxidation-resistant materials are used too much.
