Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the air-conditioning system air flow line containing the silver-zeolite-based and silver nano-based antimicrobial agent according to the present invention will be described in detail.

Figure 2 is a perspective view showing the air conditioning system of the present invention is applied to the air flow line of the vehicle, the characteristics of the present invention is a low-density polyethylene (LDPE) base resin (silver-zeolite) and (silver-zeolite) and The silver nano-based antimicrobial agents are each blended in a predetermined ratio, mixed through a super mixer to prepare a master batch, and then blow molded or injected into the master batch to produce an air conditioning system air flow line. have.

By prescribing antimicrobial products to air flow lines such as air conditioners in the manufacturing stage, not only the vehicle is running but also the eradication and reduction of bacteria in the air flow line can be achieved. The role of the antimicrobial agent in the present invention can promote a continuous antimicrobial effect over the life of the vehicle.

Silver (Ag), a precious metal, has been used as a material that possesses antibacterial and bactericidal properties for about 5,000 years.The product has been chemically bonded with zeolite or nanoparticles to increase the specific surface area. Antimicrobial activity persists in spite of the small amount of the product using the improved product. In case of bacteria, silver component penetrates into the bacteria, destroys them with cell membrane binding, and shows antibacterial activity through the mechanism of killing bacteria.

Zeolite is a kind of feldspar mineral, filled with water molecules in the nano-sized pores inside, and when the ore is heated, the contained water molecules evaporate to generate water.

The zeolite is a fine porous material generated by the action of volcanic ash of the three tertiary layers, and has excellent physical adsorption to nitrogen, phosphoric acid, cyanide, etc., and has excellent chemical cation substitution effect, so as to absorb up to 20 times of gas other than water, Excellent ability to adsorb.

The present invention, by using the characteristics of the silver and zeolite as described above applied to the air flow line manufacturing of the air conditioning system, in particular to increase the number of possession to promote the health of the vehicle occupants gradually recognized as a necessity, It is designed to suppress the occurrence.

According to one embodiment of the present invention, a low density polyethylene (LDPE) base resin is first blended with a powdery silver-zeolite based antimicrobial agent in an amount of 18 to 20% by weight, and an organometallic fatty acid ester and an oxidative stabilizer compared to the base resin. 0.5-2.0 wt% and 0.2-1.0 wt% are added respectively.

At this time, limiting the blending ratio of the powdered antimicrobial agent to 18 to 20% by weight is inefficient for the use of the base resin when added to less than 18% by weight, the dispersion of the base resin is less than 20% by weight.

In addition, the content of the organometallic fatty acid ester is limited to 0.5 to 2.0% by weight, the dispersibility of the antimicrobial agent is not expressed when added less than 0.5% by weight, the dispersibility of the low molecular weight in the base resin is good To reduce the mechanical properties.

In addition, the content of the oxidative stabilizer is limited to 0.2 to 1.0% by weight when the addition of less than 0.2% by weight does not develop oxidative stability when raised above the heat-resistant limit temperature due to the antimicrobial agent, resulting in yellowing of the base resin, 1.0 This is because the addition of excessive powder form by weight leads to low cost and mechanical properties.

Thereafter, the inputs are mixed using a super mixer, and the mixed raw materials are manufactured using a extruder to produce a master batch chip, and the master batch chips are made of high density polyethylene (HDPE), which is a raw material for manufacturing an air flow line. ) And 0.5 to 0.7% by weight of polypropylene (PP).

At this time, limiting the content of the master batch chip to 0.5 to 0.7% by weight is less than 0.5% by weight of the antimicrobial expression effect is lowered, when exceeding 0.7% by weight of the use of excessive antimicrobial agent causes a decrease in cost and mechanical properties Done.

Thereafter, the air flow line is manufactured by a conventional blow molding or injection process.

Meanwhile, according to another embodiment of the present invention, 180 to 220 ppm of a liquid silver nano antimicrobial agent is added to a low density polyethylene (LDPE) base resin, but the limit of the antimicrobial agent to 180 to 220 ppm is limited to less than 180 ppm. When added, the base resin becomes inefficient due to the use of the base resin, and when added in excess of 220 ppm or more, the addition of an optimum content to the final target resin becomes difficult.

Thereafter, the base resin and the antimicrobial agent are mixed by using a super mixer, and the mixed raw material is manufactured by using a extruder to prepare a master batch chip, and the master batch chip is a raw material for manufacturing an air flow line, high density polyethylene (HDPE) and It contains 15-20 ppm in polypropylene (PP).

At this time, limiting the content of the master batch chip to 15-20 ppm is difficult to express antimicrobial activity as a required component when less than 15 ppm is added. The phenomenon becomes noticeable.

Thereafter, the airflow line is manufactured by blow molding or injection process.

Hereinafter, the present invention will be described in more detail with reference to Examples.

Subsequently, these blended raw materials were prepared using an extruder to produce a master batch chip, and the prepared master batch chip was contained 0.6 wt% of high density polyethylene (HDPE) and polypropylene (PP), which are plastics for air flow line manufacturing, Air flow lines were prepared via blow molding or injection processes.

(Example 2)

The low density polyethylene (LDPE) was used as a base resin, and 200 ppm of silver nano solution of the alcohol base was mix | blended with this low density polyethylene, and it mixed using the super mixer.

Subsequently, these blended raw materials are manufactured through an extruder to produce a master batch chip, and the master batch chip is contained in high density polyethylene (HDPE) and polypropylene (PP), which are plastics for air flow line manufacturing, and then the final product is an air flow line.

During the summer or winter, when the air conditioner or the heater is operated, cool or hot wind is introduced through the side vents 12, the center vents 14, the driver's seat vents 18, and the passenger seat vents 19 of the air flow line 10, In the case of luxury vehicles, the heater and the air conditioner come out to the rear seat through the rear vent (15).

At this time, since the air flow line 10 itself is made of an antibacterial material, it is possible to prevent the growth of bacteria or bacteria, as well as to prevent bacterial diseases caused by these bacteria or bacteria.

As a result of the antimicrobial test, the bacterium showed a 100% bacterial reduction rate against Staphylococcus aureus (ATCC 25923 and ATCC 6538P), Escherichia coli and Escherichia coli O-157, and the air flow line 10 according to the present invention performed a process such as rainwater inflow or washing. Even if it goes through, there is no possibility of losing antimicrobial agent, so it maintains antibacterial ability for a long time.

In addition, despite the inclusion of these antimicrobial agents, the mechanical properties of the raw material HDPE and PP are maintained at 95% or more, which makes it possible to use them without affecting the mechanical strength required in the material.
