Description
The present invention relates to an antibacterial plastic which improves moldability while securing an antimicrobial activity above a predetermined value when a certain amount of antibacterial copper powder having a certain level of antibacterial activity is mixed with plastic and molded into a certain form.
In general, when using a plastic material, non-ferrous metal materials such as silver, copper, and gerolite, which have antibacterial properties to sterilize specific microorganisms harmful to human body or prevent reproduction of specific microorganisms through plastic, A molding technique is known.
More specifically, many plastic products, including general household goods, are made of materials such as polystyrene resin, polyethylene resin, melamine resin, urea resin, ABS resin, urethane resin, and silicone resin.
These plastic materials are continuously increasing in use due to their ease of use, economic efficiency, excellent processability and functionality, and the products manufactured using plastic materials include Salmonella, Pneumococcus, Methicillin Resistant Staphylococcus Aureus (MRSA) , Staphylococcus aureus, and Pseudomonas aeruginosa are often exposed to environments where they can reproduce.
For example, algae are generated in household humidifiers, Salmonella bacteria live in filter parts of air conditioners, and Escherichia coli is grown in drinking water storage containers or refrigerators. In addition to plastic materials, They are inhabited and transferred to the human body, causing disease.
One of the common techniques for preventing the habit of these household goods is to form zeolite in the plastic of the food storage container. This is done by using the ion exchange property of zeolite to replace part of the cation with anion and have antimicrobial properties. Thereby maintaining the quality of the food or maintaining the quality of the food.
However, because the zeolite is contained in plastics due to its water-solubility, the zeolite emits moisture of 15 wt% of the total weight during the high-temperature processing, resulting in deterioration of the physical properties of the resin, Visible problems are occurring.
In order to solve the problem associated with the use of the zeolite, Korean Patent Registration No. 0502315 discloses a method for producing an antimicrobial resin, which comprises one of silver, copper, tin and arsenic ions and contains zirconium and sodium as main components Based inorganic metal-containing carrier is added to the plastic.
More specifically, the antimicrobial material of the prior art has a ratio of zirconium and sodium of 8: 2, and the silver or copper or tin or arsenic ions, which are inorganic materials, are carried thereon in an amount of 80 to 120 ppm based on the weight of the powder, .
In order to minimize the influence on dispersibility and transparency when applied to plastics, the powder particle size of the inorganic material is formed in the range of 0.5 to 1.0 탆, and the antibacterial material composed of the zirconium and sodium and the inorganic material ion powder is added to the plastic in the range of 0.1 By weight to 1.0% by weight.
The kind of the plastic to which the antibacterial material is added is not particularly limited, but polyester, polycarbonate, polyamide, polypropylene, acrylonitrile-butadiene-styrene copolymer is used.
However, the above-mentioned prior art is formed by mixing antimicrobial materials added to plastics with zirconium, sodium and inorganic materials, and there are many kinds of constituent elements for forming antimicrobial materials. Especially, zirconium is a component material of nuclear power generation and aircraft and spacecraft The world is considering zircon, which is a raw material of zirconium, as a strategic material, which makes it difficult to purchase easily and the supply is not smooth, which is a problem in that the cost of antibacterial material is high.
As an example of conventional antibacterial plastics, there is an antimicrobial plastic of Patent Application No. 10-2014-0061871, which was invented by the inventor of the present invention. The antimicrobial plastic is composed of 99 wt% to 99.1 wt% of plastic material and 0.1 wt% And the antimicrobial copper powder is formed into a powder having a particle size of 40 to 60 占 퐉 by mixing the antimicrobial copper powder with a powder of Salmonella, And the rate of post-bacterium reduction is 99.9% or more.
The antimicrobial plastic of the prior art filed by the present inventor is to mix spherical antimicrobial copper powder having a size of 40 to 60 占 퐉 in the plastic, Although the injection property is good during processing, the amount of the powder is increased in order to improve the antibacterial power, and if the speed of the antibacterial action is shortened, the injection molding property is inferior.
In other words, when the antibacterial copper spherical powder is mixed with plastic and injected, phenomena such as cracking, wrinkling, thinning, skid mark occur in the molded product, There arises a problem that a spring back phenomenon occurs in which the shape is twisted or deformed.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide an antimicrobial material which can reduce manufacturing cost by simplifying the composition of an antimicrobial material mixed with a single material of non- It is an object of the present invention to provide an antibacterial plastic which is capable of improving moldability upon injection while maintaining an antimicrobial activity above a certain level.
In order to solve the above problems, the present invention provides an antibacterial plastic in which a plastic and an antibacterial copper powder are mixed, wherein the antibacterial plastic is a master batch or compounding compounding method Based on a dispersant based on an ester compound so that the antibacterial plastic is uniformly dispersed in the inside of the plastic, and a calcium oxide-based dispersant for absorbing moisture due to the micro condensation of the antibacterial copper powder generated due to the difference in the outside air temperature The antimicrobial copper powder is processed into a powder having an average diameter of 15 to 75 탆 and a powder having a length of 10 to 75 탆, a width of 10 to 75 탆 and a thickness of 3 to 10 탆. Shaped powder, and 70 wt% of spherical powder and 1 wt% of flake-like powder And 30% by weight of horse powder are mixed to form a mixed antibacterial copper powder to improve moldability.
When the antimicrobial plastic is injection molded by the master batch compounding method, 95 to 97% by weight of the plastic and 3 to 5% by weight of the master batch are blended with 100% by weight of the antibacterial plastic.
When 3 to 5% by weight of the masterbatch is compounded and molded, 3 to 5% by weight of the masterbatch is used as 100% by weight and 85% by weight of the plastic, 10% by weight of the mixed antibacterial copper powder, 4% 1 wt% of the moisture absorbent is blended.
When the antibacterial plastic is injection molded by the above compounding method, 96.5 to 98.5% by weight of plastic is mixed with 0.5 to 2% by weight of mixed antibacterial copper powder, 0.5 to 1.5% by weight of dispersant and 0.05 to 0.1% by weight of hygroscopic agent, .
The antimicrobial plastic is characterized in that all of the bacterial reduction rates after Salmonella, Pneumococcus, MRSA, Escherichia coli, Pseudomonas aeruginosa, and Streptococcus pneumoniae are 85% or more after 3 hours, It should be applied to part of product.
The effect of mixing the antibacterial copper powder made of a single material having a large antibacterial activity on plastics to simplify the construction of the antibacterial material and mixing the antibacterial copper powder with the generally used low cost plastic, .
Also, by limiting the amount of the antibacterial copper powder added to the plastic to a predetermined value or less, the antimicrobial power of the antimicrobial plastic is generated within a short time within a short time, and the antimicrobial copper powder contained in the plastic is increased, There is an effect that an antimicrobial plastic product can be produced.
Further, the antimicrobial plastic according to the present invention can be formed into an antibacterial plastic, such as a household article, a household appliance, a food container, a toy, etc., An effect of preventing bacterial contamination is generated.
1 is a view showing an embodiment of an antibacterial plastic according to the present invention.
2 is a view showing a spherical powder.
3 is a view showing a flake type powder.
The present invention is described in detail below. It should be understood that the claims of the present invention are not limited to these embodiments, but include all objects belonging to the same category.
The antimicrobial plastic having improved antibacterial activity and having a certain degree of antibacterial activity according to the present invention is injection molded by a master batch or compounding compounding method generally known in the plastic injection molding field.
When the above-described antibacterial plastic is injection-molded through masterbatching or compounding blending, all of the mixing methods are carried out by mixing the antibacterial copper powder in a plastic and dispersing the antibacterial copper powder in the plastic as uniformly as possible, A dispersant and a moisture absorbent based on calcium oxide are mixed so as to absorb the moisture due to the micro condensation of the antibacterial copper powder generated due to the temperature difference of the outside air temperature.
The base material of the antibacterial plastic and the plastic used for forming the masterbatch are materials such as a polyvinyl chloride resin, a polyethylene resin, a polystyrene resin, a polypropylene resin, an ABS resin, a phenol resin, a urea resin, a melamine resin, a urethane resin, , It is preferable to select a plastic material of a kind which mainly makes contact with the human body or manufactures daily necessities that people use on a daily basis.
As shown in FIG. 2, the antimicrobial copper powder is prepared by mixing spherical powders obtained by processing antimicrobial copper into powders having an average diameter of 15 to 75 탆 and a spherical powder having a length of 10 to 75 탆 and a width of 10 to 75 탆, The antibacterial copper powder to be mixed with the plastic is mixed with a mixed antibacterial copper powder which is a mixture of 70% by weight of spherical powder and 30% by weight of flake powder based on the total weight of the antibacterial copper powder .
The above-mentioned antibacterial copper powder may be generally used, and it is preferable to use an antibacterial copper material which is recognized as an antibacterial effect internationally.
In the case of an embodiment in which 100% by weight of the antimicrobial plastic is injection molded by the master batch compounding method, 95 to 97% by weight of the plastic and 3 to 5% by weight of the master batch are mixed and molded.
In the case of mixing 3 to 5% by weight of the master batch with the master batch, the master batch is prepared by mixing 3 to 5% by weight of the master batch with 100% by weight of the master batch, 10% 4% by weight of the dispersant and 1% by weight of the moisture absorber are mixed.
That is, when 100 kg of the antibacterial plastic is injection molded by the master batch compounding method, 95 to 97 kg of the above plastic and 3 to 5 kg of the master batch are mixed and molded. When 3 kg of the master batch is mixed, 2.55 kg of the above- 0.3 kg of the above dispersant, and 0.03 kg of the above-mentioned moisture absorber were mixed. When 5 kg of the master batch was mixed, 4.25 kg of the plastic and 0.5 kg of the mixed antibacterial copper powder, 0.2 kg of the dispersant and 0.05 kg of the hygroscopic agent were mixed .
An example of injection molding of an antibacterial plastic by the above compounding method is as follows. In the case of injection molding of 100% by weight of an antibacterial plastic, 96.5 to 98.5% by weight of plastic, 0.5 to 2 wt% of a powder, 0.5 to 1.5 wt% of a dispersant, and 0.05 to 0.1 wt% of a hygroscopic agent are mixed and molded.
That is, when 100 kg of the antibacterial plastic is injection-molded by the compounding compounding method, 96.5 to 98.5 kg of plastic, 0.5 to 2 kg of the antibacterial copper mixed powder, 0.5 to 1.5 kg of the dispersant, and 0.05 to 0.1 kg of the hygroscopic agent are mixed. Although the antimicrobial plastics may be produced by compounding, the present invention will be described with reference to the case where the antimicrobial plastics are produced by the master batch compounding method.
In forming the mixed antibacterial copper powder, when the average diameter of the spherical powder is less than 15 탆, the formability of the antibacterial plastic is excellent because the particle size of the powder is small. However, since the powder is not uniformly dispersed in the mixed plastic, The antimicrobial activity of the antimicrobial plastics is not uniformly generated in the whole area.
If the average diameter of the spherical powder is more than 75 탆, the moldability of the antibacterial plastic is lowered due to the large particle size of the spherical powder, and the flow is limited due to the collision between the particles having a large particle size and the plastic particles. There is a problem that the antibacterial power of the injection-molded antibacterial plastic is not uniformly generated in the whole area.
When a flake-shaped powder having a length of 10 to 75 mu m, a width of 10 to 75 mu m, and a thickness of 3 to 10 mu m and having a length and width of 10 mu m and a thickness of less than 3 mu m is formed, When the antibacterial copper powder contained inside the antibacterial plastic has a small contact area with the outside and the antibacterial power is decreased and the length and width are 75 μm and the thickness exceeds 10 μm, the area occupied by the antibacterial copper powder within the antibacterial plastic The antimicrobial activity is increased, but the antimicrobial copper powder is exposed to the surface of the antimicrobial plastic, and the surface becomes rough.
As described above, the mixed antibacterial copper powder mixed with the plastic is formed by mixing 70 wt% of the flake type powder and 30 wt% of the spherical type powder with respect to the total weight of the mixed antibacterial copper powder.
When the mixed antibacterial copper powder is mixed with less than 70% by weight of the flake-type powder with respect to the total weight of the mixed antibacterial copper powder, the spherical powder is mixed with the flake-type powder as much as that, The antimicrobial plastics produced by the injection molding have a problem that the antibacterial activity is not constant and uniform.
On the other hand, when the flake-type powder is mixed in an amount of more than 70% by weight, the spherical powder is relatively less mixed and the antibacterial power is increased because the contact area of the antibacterial copper powder and the harmful bacteria increases. However, There is a problem that the powder is exposed and the surface becomes rough.
In order to demonstrate the antimicrobial effect according to the present invention, the following antibacterial test was carried out by the film adhesion method (KCL-FIR-1003, Korea Construction & Testing Environment Institute).
