Description
The present invention relates to a resin composition containing green tea, and more particularly, to a resin composition containing green tea or a functional additive, which is a kind of raw material developed to be suitable for manufacturing a resin product which is beneficial for human body and is environmentally friendly.
In general, Resin is a material that is actively applied to the production of molded articles having various shapes by being meltable, combustible, and capable of solidification.
Examples of commercialization of such resins include various types and shapes of containers, sheets, films, PET, infant products, adult products, and the like. The raw materials for producing these resins are disclosed as strong functional compositions. Patent Publication No. 2001-0078131 discloses an example having excellent moldability, chemical resistance, deodorization, post-processability, and antimicrobial properties.
However, in the case of the above-mentioned patents, there is a disadvantage in that acidity changes during prolonged use due to commercialization of the product, shortening of service life due to a decrease in flexibility, and leaching of harmful components during boiling or heating.

Examples of such methods include Published Publications 2006-0124927, 2002-173563, 2005-88985, and 2013-0046842.
However, they are difficult to process various resin products due to a decrease in formability due to the addition of a large amount of composite materials, and in some cases, excessive amounts of alumina and ceramics are contained, Or it may cause problems that shave the skin and cause dermal damage.
In addition, when it is made of resin containers, food and beverage should be stored. There is a high risk that harmful substances may be harmed by the release of harmful substances.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the prior art, and it is an object of the present invention to provide a resin product which is produced as a resin product and is used for a long time without elution of harmful substances, excellent in workability, excellent in antibacterial property, And which is excellent in tensile strength and is not easily broken. The present invention provides a resin composition containing green tea which is environmentally friendly.
As a means for achieving the above object, the present invention provides a green tea composition comprising 40-60% by weight of a green tea mixture, 10-20% by weight of a rubber solution and 30-40% by weight of acetone as an organic solvent, wherein the green tea and silicone are mixed at a weight ratio of 2: ; 10 to 15 parts by weight of PVA fiber as a functional additive component with respect to 100 parts by weight of the main component; 2-4 parts by weight of Polysorbate 80; 5-10 parts by weight of powdery phase light of 200-300 mesh size; And 4-8 parts by weight of an antimicrobial agent composed of 2-4% by weight of polyalkyl nitrile, 12-16% by weight of polyoxyalkyl ether, 10-14% by weight of isopropyl alcohol and the balance of water, to provide a resin composition containing green tea .
Also, the main component may be composed of 50-70 wt% of a green tea mixture and 30-50 wt% of acetone, which are organic solvents, in a weight ratio of 2: 1 of green tea and silicone.
The main component may be 40-60 wt% of green tea, 10-20 wt% of rubber solution, and 30-40 wt% of acetone as an organic solvent.
In addition, the main component may be composed of 50-70 wt% of green tea and 30-50 wt% of acetone as an organic solvent.
According to the present invention, since the antimicrobial function by green tea is expressed, the hygienic property is improved, and the product has excellent moldability and processability as well as environment friendliness, so that it is easy to produce products in various forms.
In addition, the resin composition is not broken easily because of its excellent tensile strength, and it is safe that it does not cause irritation even when the skin comes in contact with the skin or damages the dermis.
Hereinafter, preferred embodiments according to the present invention will be described in detail.
Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.
In addition, embodiments according to the concept of the present invention can make various changes and have various forms, so that specific embodiments are described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
The present invention is based on the premise that a mixture containing green tea, silicone and rubber is the main component and that various functional additives are incorporated therein to improve workability and moldability of the resin product, The present invention provides a resin composition containing green tea which prevents irritation upon skin contact, maintains neutrality without change in acidity even after prolonged use, and is excellent in tensile strength and is not easily broken.
To this end, the resin composition containing green tea according to the present invention comprises 40-60% by weight of a green tea mixture, 10-20% by weight of a rubber solution and 30-40% by weight of acetone, which are organic solvents, in a weight ratio of 2: %; 10 to 15 parts by weight of PVA fiber as a functional additive component with respect to 100 parts by weight of the main component; 2-4 parts by weight of Polysorbate 80; 5-10 parts by weight of powdery phase light of 200-300 mesh size; 4-8 parts by weight of an antimicrobial agent consisting of 2-4% by weight of Polyalkyllo Nitrile, 12-16% by weight of Polyoxyalkyl Ether, 10-14% by weight of isopropyl alcohol and the balance of water.
At this time, when the resin composition according to the present invention is used particularly for the production of baby articles or food storage, 15-20 parts by weight of ion calcium may be added to 100 parts by weight of the main component.
In this case, ionic calcium provides a complementary effect to regulate and supplement calcium ion concentration upon absorption into the body as well as to block harmful substances. When added in excess, ionic calcium is adversely affected and should be limited to the above range.
In addition, 20-30 parts by weight of aloe vera gel may be added to 100 parts by weight of the main component so as to maintain the neutrality by inhibiting the acidity change during resin production.
The aloe vera gel is a component mainly used for health supplement foods or cosmetics. However, since the latex component is contained in the form of a gel in the present invention, the binding effect is improved without changing the acidity and the sterilizing power against bacteria and fungi It is added for toxin neutralization function.
However, at least 20 parts by weight should be added in order to exhibit the effect, and when it exceeds 30 parts by weight, viscosity tends to be high and moldability is deteriorated.
Hereinafter, functions and numerical limitation reasons of main components and functional additives of the resin composition of the present invention will be described.
Firstly, green tea, as well known, gives mental vitality when taken by car, refreshing the mood, inhibiting the growth of various bacteria, preventing poisoning and cold, and preventing postprandial tea from breeding mouth bacteria It is known that it reduces the cholesterol content of blue to inhibit the onset of hypertension and arteriosclerosis, as well as to prevent cancer, to inhibit the proliferation of cancer cells, and to decompose toxins of liver.
It is known to be due to the abundance of polyphenols, which are carcinogenic inhibitors contained in green tea. It is known that catechin in green tea binds with heavy metals or nicotine in the body and excretes it to the outside of the body. It digests glycogen, To reduce weight and to prevent the effect of obesity is reported.
However, such green tea has been used only for the purpose of taking it, but it is not applied to resin products. This emphasizes only the pharmacological effects of absorption through the body in the oriental medicine, and the application to other fields is also insignificant.
Therefore, in the present invention, such a green tea is positively utilized in a resin container or a baby article which is in contact with the skin, so that characteristics unique to green tea can be exhibited.
For this, in the present invention, green tea powder or liquid green tea extract can be utilized. In order to improve processing and moldability, green tea powder should maintain a particle size of 100-200 mesh, that is, 140-74 μm.
In addition, silicon is added in a liquid phase, not a complete liquid phase such as water, but a mucilage, or more precisely, a paste.
That is, the silicone may be characterized by having a crosslinked polymeric microparticle matrix (elastomer) component dispersed in a fluid component. The fluid component is sufficiently compatible with the elastomer, trapping in the matrix or causing expansion of the fine particles. These silicone compositions provide a smooth and smooth low-residue feel at dry-down to provide flexibility in resin production.
In particular, since the conducting cone is poor in hydrophilicity, the hydrophilic property may be increased by special treatment of the silicon surface for hydrophilizing. However, in this case, the cost is increased and the air is increased. Therefore, in the present invention, To lower the viscosity, and to make it hydrophilic by using an emulsifier such as polysorbate 80 as described below for low-cost and environmentally friendly methods for affinity with water.
Such liquid silicone is expanded during the heating process for molding, and is polymerized while collecting the green tea component. Therefore, the ratio with the green tea is very important.
That is, in order to maximize the efficacy of green tea, it is necessary to balance the amount of liquid silicon to be expanded. Therefore, it is most ideal when green tea: liquid silicone is mixed at a weight ratio of 2: 1.
Therefore, in the present invention, the green tea mixture constituting the main component of the resin composition should be added in an amount of 40-60 wt% with liquid silicone. This is because the resin has to be molded, When it is added in an amount of more than 60% by weight, the green tea is added as a powder, which deteriorates the formability and processability of the green tea. In addition to the inhibition of binding, And thus should be limited to the above range.
In addition, the rubber liquid is added to inhibit the overheating of the liquid silicone and to maintain the elasticity of the product and to inhibit the dissolution of harmful substances through anchor woven reaction with the crosslinked liquid silicone.
Such rubber liquid should be added in a range of 10-20% by weight. If it is less than 10% by weight, it is not effective. If it exceeds 20% by weight, hardening is inhibited, It should be limited to the above range.
Acetone is used as an organic solvent for the liquid silicone. To lower the viscosity, acetone should be added in a range of 30-40 wt.%. If it is added in an amount of less than 30 wt%, liquid silicone may be saturated, And when it exceeds 40% by weight, the viscosity is rapidly decreased, so it should be added at a lower rate.
The present invention also provides a functional additive other than the main component constituting the above-mentioned resin composition, which further comprises PVA fiber, polysorbate 80, powder phase ilite, and antimicrobial agent. In this case, the PVA fiber increases tensile strength And polysorbate 80 is added as an emulsifier, and powdery emitite is added for purifying function and inhibition of release of harmful substances and adsorption removal, and antimicrobial agent is added especially for increasing antimicrobial activity in containers and baby products .
For example, the PVA fiber is a hydrophilic material having an OH-group, and usually has good physical and chemical adhesion, and has a tensile strength of 900 to 1,600 MPa. Therefore, the PVA fiber is suitable for demanding tensile strength and alkali resistance.
In addition, since the combustion heat is the lowest in synthetic fibers and no harmful gas is present in the gas generated during combustion, it can be said to be environmentally friendly.
Particularly, since the PVA fiber is a binder but also a fiber, it forms voids therebetween and reduces cracks, which is one of the very important materials among the functional additives of the present invention.
If the PVA fiber is added in an amount exceeding 15 parts by weight, it is not suitable for a product such as a container because the pore becomes too large to increase water permeability. When the PVA fiber is added in an amount of less than 10 parts by weight, The water permeability is deteriorated.
The Polysorbate 80 also includes crosslinking function as a nonionic surfactant and an emulsifier derived from sorbitol.
In addition, since it has a preservative function, it can prevent deformation of containers and resin products, increase durability, and lead to achieve longevity.
When polysorbate 80 is added in an excessive amount, the surfactant function is increased to deteriorate the moldability, so a small amount of 2-4 parts by weight should be added in the above range.
In addition, the powdered ilite also functions as an air purification function through far infrared ray and anion, but it has an admiral function and is added for adsorption elimination and inhibition of dissolution of harmful substances.
As the particle size of such powdery phase light increases, the grinding processing ratio increases and the harmful component adsorption effect takes a short period of time. Therefore, when the particle size is 10 years or more, the adsorption and anion radiation function are drastically decreased. On the other hand, But it is preferable to provide the above-mentioned particle size and component content because it is long-term but weak, the homogeneity of the product is lowered, and the ventilation of the mortar is increased to deteriorate the blocking ability of harmful substances.
That is, if it is added in an amount of 5 parts by weight or less, the adsorption effect and the effect of blocking the harmful substances are drastically decreased and the bonding strength is lowered, and if added in an amount exceeding 10% by weight, the strength is lowered.
The antimicrobial agent is a well-known antimicrobial agent and is added because it has excellent adhesion and good deposition ability and does not deteriorate its antimicrobial activity even when used for a long time. Especially, it is effective for staphylococci including Escherichia coli and Pseudomonas aeruginosa. It should be added to the above range.
The resin composition having such a composition can be formed into various resin product groups according to the molding method, as described above.
In particular, it can be made into a resin product having various shapes and shapes through various molding methods such as injection molding, heating press, extrusion and the like.
The present invention is to provide a kind of raw material capable of producing such a resin product, particularly a composition combined so as to exhibit special characteristics, and since the product itself is not characterized by the product itself, It is omitted. However, in order to confirm the characteristics, the following embodiments will be described.
In addition, since the resin composition according to the present invention is a raw material, it can be combined in various forms depending on the kind of the molded article. In some cases, silicon or rubber can be excluded when the main component is constituted. The resin composition according to the present invention may have the following composition within a range that can be modified in addition to the above-mentioned composition.
That is, as another composition example, the main component is composed of 50-70% by weight of a green tea mixture and 30-50% by weight of acetone, which are organic solvents, mixed in a weight ratio of 2: 1 of green tea and silicone; 10 to 15 parts by weight of PVA fiber as a functional additive component with respect to 100 parts by weight of the main component; 2-4 parts by weight of Polysorbate 80; 5-10 parts by weight of powdery phase light of 200-300 mesh size; 4 to 8 parts by weight of an antibacterial agent composed of 2-4% by weight of Polyalkyllo Nitrile, 12-16% by weight of Polyoxyalkyl Ether, 10-14% by weight of isopropyl alcohol and the balance of water.
