Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for manufacturing a vinyl glove,

The present invention relates to a method for producing a vinyl sanitary glove containing a natural component, and more specifically, by limiting the amount of a natural plant powder to a maximum of 5 parts by weight, the surface is roughened, transparency is not lowered, And even when a small amount of natural plant powder is added through the pretreatment process, the content of the active ingredient of the plant can be maximized, and by controlling the particle size and the amount of the natural plant powder, the natural plant powder is burned in the extruder To a method for producing a vinyl sanitary glove containing a natural component capable of preventing clogging of an extrusion nozzle and improving dispersibility and moldability.

In general, plastic hygiene products include hygienic bags (zipper bags, kimchi kimchi bags, clean wraps) to store food at home or restaurants, and sanitary gloves to protect hands.

Among them, hygienic gloves are made of low-density polyethylene resin, which is used as a disposable one, which is worn on the hand and is cheap and hygienic.

These hygiene gloves are not hygienic because they do not get food on their hands, and gloves are made of thin vinyl, so you can work without gloves when you work gloves.

However, due to the nature of sanitary gloves, airtightness and watertightness are maintained so that the air can not be circulated at the same time as wearing, and the sweat on the hands is inevitable, so that the sanitary gloves stick to the hands and have a very uncomfortable and moist feeling. And the antimicrobial properties are low. Therefore, it causes problems such as housewives eczema and gall bladder in the case of wearer for a long time.

In order to solve such a problem, Korea Patent No. 10-1439036 discloses a method of pulverizing green tea and an acidic sea powder, pulverizing the pulverized green tea to have a particle size of 140-74 mu m, 15 to 25% by weight of ground green tea powder was added to the low density polyethylene resin as a main component, and the mixture was stirred for 10 to 20 minutes. Then, 1-5 wt% of acidic foil powder and 2-4 wt% of hyaluronic acid A mixing step of mixing the mixture for 10 to 20 minutes to prepare a resin mixture; A pellet processing step of completing the kneading and pelletizing the resin mixture while extruding the resin mixture into an extruder; And a sheet film forming step of extruding the pellet again to form a sheet film. The method for producing a sheet film containing green tea is disclosed.

However, since the content of the powder (15-25% by weight of green tea powder and 1-5% by weight of powder of acidic silica powder) is excessive, a large amount of the powder is burnt in the extruder during molding to cause discoloration, There is a problem that the extrusion nozzle is easily clogged.

In addition, there is a problem that physical properties such as tensile strength are lowered due to excess powder, surface roughness is poor, and haziness is deteriorated due to turbidity.

In addition, since the pellets are first extruded and processed into a film by extruding the pellets in a second order, the production is complicated and excessive powder causes a rise in cost, which is suitable for manufacturing disposable sanitary articles It is not.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention of the user, the operator, or the precedent. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1 is a block diagram showing each step of the process for producing a vinyl sanitary ware containing a natural component according to the present invention. FIG. 2 is a view showing a state in which the synthetic resin and the natural plant powder of the present invention are fed into an extruder, FIG.

Referring to FIGS. 1 and 2, a method for manufacturing a vinyl sanitary article containing a natural component according to the present invention comprises steps S1 to S3.

Specifically, the method for producing a vinyl sanitary ware containing a natural component according to the present invention comprises the steps of: (1) preparing a natural plant powder by pulverizing the plant in a dry state; (2) 5 parts by weight of the natural plant powder, and step S3 of forming the synthetic resin mixed with the natural plant powder into a sheet form.

The vinyl sanitary article containing the natural component of the present invention can be exemplified by being processed into a sanitary glove, a sanitary bag, a wrap, a zipper bag or the like, but is not limited thereto.

The plant may be one selected from green tea leaves, bamboo leaves, rice bran, aloe and pine leaves, dandelion, and white leaves.

The green tea leaves contain caffeine, tannin, theanine, siccinol, vitamins, niacin, pentotenic acid, etc. Containing a large amount of ingredients that constantly work to prevent aging or roughness of the skin, And it is known that it can maintain moisture retention.

The bamboo leaves have a strong bactericidal and insecticidal effect due to the action of polyphenol peptide and silica, which are the main components, and are effective for skin beauty by anti-inflammatory and anti-inflammatory action, and have a radiation shielding effect, a toxicity of heavy metals and an environmental hormone It is known to have an effect.

It is known that the rice bran has the toxic effect of heavy metals and detoxification of environmental hormones, skin whitening and moisturizing effect and has a therapeutic effect on skin diseases due to the action of phytoinic acid and selenium which are main components.

The aloe has a strong and direct sterilization effect due to the action of the main ingredient, aloe tine, and has a wound and skin soothing effect, wart, corn, hard flesh removal effect, allergy prevention effect, skin moisturizing effect, .

The pine leaves contain phenol compounds and terpenes, which are known to detoxify, activate metabolism, and prevent bacterial growth because of their bactericidal action.

 The dandelion is known to contain anti-inflammatory and antioxidative activities, including fatty acids such as choline, silymarin, behenic acid, and inulin, and contains taraxerol, betasitosterol and caffeic acid have.

The leucorrhoeae contain an effective ingredient such as elemol, and are known to have effects such as dermatitis, atopy, and soothing of the skin.

The natural plant powder is preferably pulverized using a ball mill or the like so as to have a particle size of at least 300 mesh, specifically 300 to 700 mesh.

According to the sheet film containing green tea of Korean Patent No. 10-1439036 and the method for producing the same, the green tea leaf powder is composed of 100 to 200 meshes. When the powder is ground to have a particle size of less than 300 mesh This is because the surface roughness is increased and the feel is deteriorated, the transparency and color of the product become hazy, and the nozzle of the extruder is easily clogged during molding.

The natural plant powder preferably has a water content of 10%, more preferably less than 5%.

For example, when the moisture content of the natural plant powder is more than 5 to 10%, the water contained therein may not be mixed or mixed well with the synthetic resin and the dispersibility may be lowered.

On the other hand, the natural plant powder of the present invention can be prepared by immersing the plant in a concentrate and pretreating the plant, and then drying and pulverizing the pretreated plant.

The concentrate may be obtained by hydrothermally extracting a plant, in which the natural plant powder can sufficiently exert the inherent efficacy of the plant even in a small amount.

Specifically, 10 to 30 parts by weight of one plant selected from green tea leaves, bamboo leaves, rice bran, aloe and pine leaves, dandelion and whitish leaves are added to 100 parts by weight of water, subjected to hot water extraction for 12 hours to 2 days, Can be exemplified.

However, if the concentrate is to extract the active ingredient of each plant, it can be obtained by extraction using hot water extraction as well as alcohol solvent.

It is preferable that the plant of the natural plant powder and the plant of the concentrate are the same. For example, green tea leaves are extracted with hot water to prepare a concentrate, the green tea leaves are immersed in the concentrate for 1 day and then taken out, dried and pulverized to a moisture content of less than 5 to 10% It is preferable to maximize the content of the effective component of the plant. Similarly, the bamboo leaf concentrate is made into bamboo leaf powder by immersing the bamboo leaf.

Thus, the pretreatment process can maximize the content of the active ingredient without increasing the weight of the natural plant powder, prevent deterioration of physical properties such as tensile strength generated when the natural plant powder is added in an excessive amount, And transparency is improved, thereby contributing to overall quality improvement.

In the step S2 and S3 of the present invention, the natural plant powder is mixed with the synthetic resin, and the synthetic resin mixed with the natural plant powder is formed into a sheet. The synthetic resin may be low density polyethylene, It is not.

Meanwhile, in the above-mentioned patent, the green tea powder and the low-density polyethylene resin are mixed to form a resin mixture, the resin mixture is first extruded and processed into pellets, and then the pellets are extruded to form a sheet film. On the other hand, in the present invention, the pellet-shaped low-density polyethylene resin and the natural plant powder are extruded in a state where they are simultaneously put into an extruder and mixed and heated.

Specifically, the pellet-shaped low-density polyethylene resin is stored in the first tank, and the natural plant powder is stored in the second tank and supplied to the extruder using an air pump or the like, respectively. By controlling the supply of the raw material at the preset weight ratio by using the metering pump, the manufacturing process can be simplified.

The synthetic resin and the natural plant powder are preferably 100 parts by weight, 1 to 5 parts by weight, and more preferably 1 to 3 parts by weight, respectively.

When the natural plant powder is less than 1 part by weight, it is difficult to sufficiently exert the effects of the plant or natural plant powder.

When the natural plant powder is more than 5 parts by weight, it is heated in the extruder and mixed with the synthetic resin, so that the carbonaceous materials are clogged with each other, which causes the extrusion nozzle to be clogged.

In addition, when the natural plant powder is excessive, the amount of the synthetic resin is relatively small, so that the dispersibility is lowered, the physical properties such as tensile strength are lowered, and the surface is roughened, so that the touch feeling may be deteriorated.

Hereinafter, preferred embodiments of the present invention will be described in detail.
