Description

Composition of synthetic resin (or rubber) from which the lubricating substance is eluted, and a method for producing the same

The present invention relates to a composition of a synthetic resin (or rubber) and a method for preparing the same, in which a lubricant is eluted when reacted with water. The present invention relates to a polyethylene resin (polyethyene glycol), titanium dioxide (TiO ₂ ), and carbonic acid in a synthetic resin (or rubber). Calcium (CaCO ₃ ), sodium polyacrylate, thickener, acryl acid, far-infrared emitter ceramic powder, antimicrobial (organic and inorganic), fragrance, skin moisturizer, etc. For shaving by injection and extrusion for the purpose of disposable disposable shaving, it is for the purpose of shaving without shaving lotion or soap bubble.

In connection with the application of the utility model application on November 02, 1994, and registered as utility model registration No. 110996 on the structure and function on October 07, 1997, it is injected into the synthetic resin (or rubber) of FIG. The extruded cover holder 5 and the cover holder fixing part 6 are characterized in that a lubricating substance is eluted when they come in contact with water, and a synthetic resin (or rubber) in the composition and manufacturing method of the present patent application. Polyethylene glycol, calcium carbonate, titanium dioxide, polyacrylonitrile, thickener, acnilic acid, skin moisturizer, far-infrared radiator ceramic powder, antibacterial agent (organic, inorganic), fragrance, etc. The process of turning the chip into a chip and the first drawing of the cover holder 5 and the cover holder fixing part 6 overcome technical difficulties such as injection molding and extrusion molding. Existing lubrication bend shaver attached to the upper part of the cover holder (5) in Figure 1, the lubrication bend itself disappears when it reacts with water, and the amount of lubricating material is removed. And, there is a problem such as to apply a little lather, the present invention is a cover holder (5) and cover holder fixing part (6) of Figure 1, that is, a significant amount of lubricating material is eluted when contacted with water in the upper and lower itself No separate shaving lotion or soap bubbles are needed, and the cover holder and cover holder fixing parts are made of synthetic resin and rubber that are not dissolved. In addition, antimicrobial function, far-infrared radiation function, skin moisturizing function, fragrance-generating function, etc., due to the composition is added in combination.

In the present invention, the present invention is a synthetic resin HDPE, LDPE, PVC, ABS, PS, PP, EVA, GPPS, HIPS, and natural rubber, synthetic rubber, injection and extrusion resin alone or mixed two or more resins of the present invention Additives, such as polyethylene glycol, calcium carbonate, titanium dioxide, sodium polyacrylate, thickeners, acnylic acid, cecyl alcohol, far-infrared emitter ceramic powders, antibacterial agents, fragrances, skin moisturizers, etc. Or rubber) and additives are separated separately without bonding, problems that additives are oxidized due to heat of melting and lose their inherent function, and when they are compounded, they do not stretch and flow like water and adhere to the cutting blade and form into chips. If it is not drawn, it is stretched (extracting like a strand of noodles) during extrusion. It should be cooled by water cooling or air cooling. The technical problem of the present invention is to provide a composition and a method for manufacturing the composition by adjusting the proportion of the mixture by the experiment of the embodiment of the composition, and the problem of not being able to extrude the molten resin in the screw of the compressor, etc. The present invention has been completed.

Figure 1 for discharging the lubricating material when the razor provided in the present invention in contact with water Figure 1 Synthetic resin and additives predominant to obtain the cover holder 5 and the cover holder fixing part 6 comprises the following components Select the raw materials to be satisfied and satisfy the process conditions of the compounding extruder to make chips.

For example, the composition of the present invention and the manufacturing process will be described in detail as follows.

Example 1

1. Synthetic resin (or rubber) --- 79.70-63 wt%

2. Polyethyene glycol --- 5-10% by weight

3. Sodium polyacrylate-5-10 wt%

4. Far Infrared Radiator Ceramic Powder --- 2-5% by weight

5.Calcium Carbonate (CaCo ₃ ) --- 5-10% by weight

6.Titanium Dioxide (TiO ₂ ) --- 1-5% by weight

7. Skin moisturizer --- 1-5% by weight

8. Antibacterial (organic, inorganic) --- 0.5-3% by weight

9. Spices --- 1-5% by weight

Example 2

1. Synthetic resin (or rubber) --- 80% by weight

2. Polyethene glycol --- 5% by weight

3. Sodium polyacrylate-10 wt%

4.Calcium Carbonate (CaCo ₃ ) --- 5% by weight

Example 3

1. Synthetic resin (or rubber) --- 74 wt%

2. Polyethene glycol --- 5% by weight

3. Sodium polyacrylate-10 wt%

4.Calcium Carbonate (CaCo ₃ ) --- 5% by weight

5.Antibacterial (organic, inorganic) --- 3% by weight

6. Spices --- 3% by weight

Example 4

1. Synthetic resin (or rubber) --- 73 wt%

2. Polyethene glycol --- 5% by weight

3. Sodium polyacrylate--10 wt%

4.Calcium Carbonate (CaCo ₃ ) --- 5% by weight

5. Far infrared emitter ceramic --- 7 wt%

In the above Examples 1-4, GPPS and HIPS were mixed in a ratio of 1 to 1, and the compound was compounded in the composition ratio of Example 1, but the polyethylene was added as an additive because the melting temperature of the synthetic resin was about 250 ° C. Recall (polylethene glycol) was first dissolved at 40 ℃ Celsius was not able to push the water support from the screw, and at 200 ℃ Celsius, sodium polyacrylate (sodium polyacrylate), the main additive in the lubrication razor, lost the lubrication function. In addition, in order for the synthetic resin and the additives to be melt-mixed and removed, there was no choice but to select a resin suitable for the amount of the additive and the melting temperature.

In order to perform this experiment, FIG. 1 of the shaving razor cover holder 5 and the cover holder fixing part 6 to manufacture a metal mold was carried out 150 experiments for 6 months. As a result, the mixing amount of the synthetic resin (or rubber) should be 70-80 wt% or more and the additive amount should not exceed 20-30 wt%. In addition, in the conventional extrusion method of compound extruder, it is necessary to extrude by air cooling rather than water cooling because the lubricating substance is already eluted in water when drawn by water cooling. In addition, in order to naturally cool the stretched resin by installing a coma in the state extruded from the die of the extruder, the length of the coma should be installed to be used as a chip chip.

Example 2 was made by using the PP for synthetic resin injection to make the extrusion melt temperature of the compounder extrusion chip at a temperature of less than 180 ℃ Celsius and set the injection melt temperature at 150-180 ℃ Celsius at the time of injection.

Example 3 added the fragrance and antimicrobial agent, Example 4 added an additional infrared ray emitter ceramic powder.

The present invention relates to a composition of a synthetic resin (or rubber) in which a lubricating substance is eluted, and a method for manufacturing the same, which is used for the cover holder 5 and the cover holder fixing part of FIG. The shaving compound (compound) like the composition of 1-4 in the injection molding machine in the shape of (5) cover holder, (6) cover holder fixing parts by assembling the razor blade and handle to separate shaving when shaving Without using lotion or soap bubbles, the water is buried in the cover holder and the cover holder fixing part, and water and additives react during use, so that the lubricant is eluted and the shave can be smoothly shaved.

In addition, a composition of a synthetic resin (or rubber) in which a lubricating substance is eluted, which is characterized by an antibacterial effect by an antimicrobial agent and a moisturizing function, a directional function far infrared radiator ceramic, and a function of smoothing blood circulation.
