Functional natural dyeing latex foam and its manufacturing method {FUNCTIONAL NATURAL DYED LATEX FOAM AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a functional natural dyeing latex foam and a method for manufacturing the same, and more specifically, to a functional natural material such as volcanic stone, loess, charcoal, jade, green tea, germanium, elvan, phytoncide, finely processed and mixed with water, and The functional natural material mixed with water is ball milled together with the vulcanizing agent and the accelerator to adsorb and liquefy the functional natural material on the surface of the vulcanizing agent and the accelerator. It is made to be uniformly dispersed throughout, so that the durability and color are excellent, and the cell and the surface are cleanly foamed.

Latex is made of rubber as a raw material, and has a number of excellent advantages over conventional cotton pillows and spring mattresses. In other words, the latex pillows support the cervical spine of the human body in sleep by its soft elasticity, and the latex mattress supports the human body in a balanced way along the curve of the human body to maintain the optimal C-shaped cervical spine and By eliminating the weight burden, you can maintain an optimal posture, which helps prevent neck discs, lumbar discs or turtle necks, snoring and sleep.

In addition, because of the excellent antibacterial properties, due to the characteristics of the manufacturing process, hundreds of millions of air cells are formed inside, so it is excellent in breathability and excellent in elasticity and elasticity, and has excellent circular restoration function. As a result, its use is spreading.

The latex can be classified into two types as follows.

-Natural Latex: Product manufactured using 100% natural rubber latex.

-Synthetic latex: It is manufactured by using synthetic rubber. It is synthesized by low temperature emulsion polymerization method using fatty acid soap as an emulsifier, and its properties change according to the percentage of mixing natural latex.

Natural latex of the two latex is superior in tensile strength or gel strength (gel strength) compared to the synthetic latex (excellent elasticity or lifespan and natural materials, there is a human-friendly advantage. However, since the raw material is expensive and mass production is difficult, there is a disadvantage that the price is expensive.

In addition, as interest in health has increased in recent years, sales of functional beddings equipped with charcoal, jade and various functional materials and far-infrared radiation materials have increased.

In the case of latex pillows or mattresses, a technique has been proposed, such as laminating a separate layer on top of the latex foam or forming a plurality of pinholes in the latex foam to form a functional material and a far-infrared radiation material to the pinholes. There was a problem such as impairing the elasticity inherent advantages of latex foam.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2004-0064467 in the 'latex mattress and functional latex mattress manufacturing method and apparatus for manufacturing the same' after aging latex stock solution for 12 to 36 hours, vulcanization accelerator, vulcanizing agent, curing agent Adding a curing accelerator, an oxidizing agent, an antioxidant, a filler and a functional additive; Foaming the aged latex stock solution for 30-40 minutes; Putting the foamed latex stock solution into a mold and then vulcanizing and molding at a temperature of 105 to 115 ° C; Washing the molded latex stock solution with water; By suggesting a method consisting of drying the washed latex at a temperature of 50 ~ 60 ℃, while adding the various functions for health while maintaining the original advantages of the natural latex mattress, the functional additive is added to the latex foam There was a problem in that it is not evenly distributed and hardened by agglomeration and is not produced evenly.

In addition, the Republic of Korea Patent Publication No. 10-2005-0105938 'The method for producing a health functional latex rubber foam resin blended with natural substances and flavors' also latex rubber solution, natural dyes and fragrances and nano silver catalyst particles, amethyst, jade, ganban stone, A method of preparing a latex rubber foam resin having antibacterial and antiseptic properties is proposed by blending germanium, tourmaline, zeolite, and sunstone in a constant ratio. However, the above-mentioned method also hardens evenly after the additives are not evenly distributed in the latex foam. There was a problem that the foaming, the Republic of Korea Registered Room No. 20-0315095 'porous latex pillow' also foamed latex stock solution by adding stone powder, there was a problem that evenly distributed and hardened evenly.

In addition, in the 'negative ion generating latex foam and its manufacturing method' of the Republic of Korea Patent No. 10-0883173, tourmaline prepared by mixing the tourmaline gemstone powder in water and mixing the mixed solution aged for a predetermined time in the natural rubber emulsion and then foam molding Anion-generating natural latex containing powder was proposed, but this method also only liquefied tourmaline ore powder with water, and when mixed with natural rubber emulsion, evenly dispersed parts of natural rubber emulsion did not form evenly dispersed and hardened evenly. There is a problem that is not distributed.

In addition, a number of techniques for applying charcoal or ocher powder on the latex pillows together with these techniques have been proposed, but the techniques may be harmful to the human body as the powder does not adhere to the latex.

By adding the functional powder to the latex stock solution or adding water to the powder by all the above manufacturing methods, the functional additives are never evenly distributed, aggregated and partially cured, and production and production of commercially available products are difficult.

Accordingly, an object of the present invention is to solve the problems of the conventional latex foam described above, the surface of the vulcanizing agent and the accelerator to functional natural materials such as volcanic stone, loess, charcoal, jade, green tea, germanium, ganban stone, phytoncide By adsorbing on and adding it to the foaming of the natural latex, the functional natural material is uniformly distributed throughout the latex foam, thereby providing a functional natural dyed latex foam having excellent durability and a method of manufacturing the same.

Another object of the present invention, by distributing the functional natural material evenly in the latex foam, to have a natural color even without a separate dyeing process to produce a latex foam that is excellent in color as well as clean cells and surfaces. In addition to this, while maintaining the advantages of the latex foam as it is to add various functionalities (far-infrared radiation, antimicrobial power, water vein wave prevention, electromagnetic wave prevention, metabolism promotion, etc.) for health.

Method for producing a functional natural dye latex foam of the present invention for achieving the above object, the step of finely processing the functional natural material to 1,000 ~ 10,000mesh mixed with water, and vulcanization of the functional natural material mixed with the water Ball milling by mixing with the agent and the accelerator, thereby adsorbing and liquefying the functional natural material on the surface of the vulcanizing agent and accelerator, injecting and mixing the liquefied additive in the latex stock solution, foaming the mixed mixture And forming, wherein the functional natural material is one or two or more selected from the group consisting of volcanic stone, loess, charcoal, jade, green tea, germanium, elvan, phytoncide, and side, and the functional natural material is 0.5 to 5 parts by weight based on 100 parts by weight of the latex stock solution is characterized in that it is used.

In addition, by adding various functionalities to the latex foam, as well as antibacterial, sterilization, deodorization, deodorizing effect, far infrared rays and anions are radiated from the functional material due to the body temperature generated in the human body to have a beneficial effect on the human body.

1 is a manufacturing process of the functional natural dye latex foam according to the present invention

Hereinafter, the present invention will be described in detail.

The method for producing a functional natural dye latex foam according to the present invention comprises the step of finely processing the functional natural material to 1,000 ~ 10,000mesh and mixing with water (S1), and mixing the functional natural material mixed with the water and the vulcanizing agent and accelerator By ball milling, adsorbing the liquefied natural substance on the surface of the vulcanizing agent and the accelerator to liquefy (S2), and adding the liquefied additive to the latex stock solution (S3), and mixing the mixed mixture It includes foaming and molding step (S4).

First, the functional natural material is finely processed into 1,000 ~ 10,000mesh and mixed with water (S1).

Here, the functional natural material is used one or two or more selected from the group consisting of volcanic stone, loess, charcoal, jade, green tea, germanium, elvan, phytoncide and the side. Hereinafter, the function of the functional natural material will be described again below.

If the functional natural material is larger than 1,000 mesh, since the adsorption is not made smoothly during ball milling with the vulcanizing agent and the accelerator, which is a post-process, it may be difficult to distribute the functional natural material evenly inside the latex foam, so that the processing is performed at 1000 mesh or more. And although the functional natural material may be processed more finely than 10,000mesh, which is not economical to process to less than 10000mesh, this is not necessarily limited.

In addition, the mixing ratio of the functional natural material and water is not limited, and the functional natural material may be mixed with a vulcanizing agent and an accelerator so that ball milling is possible. For example, the mixing ratio of the functional natural material and water is 1 by volume. : It can be about 0.5 ~ 3.

Here, when the functional natural material is in a liquid state, it is obvious that the powdering process may be omitted, mixed with water, or used as it is.

In addition, the functional natural material is preferably used by 0.5 to 5 parts by weight based on 100 parts by weight of the latex stock solution, which will be described later, when the functional natural material is less than 0.5 parts by weight, its functionality becomes insignificant, exceeding 5 parts by weight If the foam is not made smoothly, rather than the inherent function of the latex foam may be lowered, it should be used within the range of 0.5 to 5 parts by weight.

When the micro-processing of the functional natural material and mixing with water (S1) is completed, the functional natural material mixed with the water is ball milled with a vulcanizing agent and an accelerator in a ball mill for at least 12 hours to the surface of the vulcanizing agent and the accelerator. The functional material is adsorbed to liquefy (S2).

When latex foaming through the adsorption and liquefaction of the functional material (S2), the functional natural material is uniformly distributed in the latex together with the adsorbent vulcanizing agent and accelerator, the functional natural material is adsorbed on the surface of the vulcanizing agent and accelerator If not, that is, if the liquefaction (S2) process is omitted, it is difficult to evenly distribute even when partially cured during foaming.

Here, as the vulcanizing agent and the accelerator, all materials commonly available in the art belonging to the art may be used, for example, sulfur as the vulcanizing agent, zinc 2-mercaptobenzothiazole (MZ) and zinc diethyl dithiocarbamate (EZ) as the accelerator. Can be mixed.

In addition, the amount of the vulcanizing agent and the accelerator is preferably used at about 0.5 to 2 parts by weight based on 100 parts by weight of the latex stock solution, and in the case of using sulfur, MZ and EZ as described above, 1 part by weight of sulfur and 1 part by weight of MZ. Parts and EZ 1 part by weight may be used respectively.

In the ball milling process, the functional additive is uniformly adsorbed on the surface of the vulcanizing agent and the promoter when mixed processing is performed for 12 hours or more, but the processing time is not necessarily limited.

Next, the ball milled to the latex stock solution is added to the liquefied additive, mixed (S3). The mixing method is not limited at the time of mixing, and the mixing ratio is 0.5 to 5 parts by weight of the functional natural material, 0.5 to 2 parts by weight of vulcanizing agent and 0.5 to 2 parts by weight of accelerator based on 100 parts by weight of the latex stock solution as described above. . In addition to the liquefied additives, a curing agent, an oxidizing agent, an antioxidant, a filler, and the like, which may be conventionally mixed when the latex is foamed, may be additionally mixed. It is preferable to use about 0.5-1 weight part each.

Then, the mixed mixture is foamed and molded (S4).

The foaming and molding process, using a foaming machine as a step to create a suitable amount of foam in the latex stock solution, when the foaming is completed, it is injected into a mold and vulcanized at a temperature of 95 ~ 110 ℃, the vulcanized latex After demolding, the foam is washed with water and dried at a temperature in the range of 50 to 60 ° C. Latex foam is a liquid latex stock is cured by reacting the latex stock solution and the vulcanizing agent through the vulcanization.

The reason for vulcanization at 95-110 ° C. for 30 minutes to 40 minutes during the vulcanization process is that vulcanization is not sufficiently achieved at less than 95 ° C., and when the mold is in excess of 110 ° C., the part where the mold and the latex stock solution come into contact is hardened. This is because elasticity is impaired, and sufficient elasticity is not achieved when vulcanized for 30 minutes or less, and elasticity is impaired when vulcanized for 40 minutes or more. The reason why the drying temperature is 50 to 60 ° C. is that the drying becomes slower than 50 ° C. and the productivity is lowered. When the temperature exceeds 60 ° C., the oxidation of latex is promoted due to the high temperature, and the characteristics deteriorate.

In addition, when manufacturing the latex foam, the higher the thickness, the higher the defective rate, the thickness is preferably within 15cm, but is not necessarily limited thereto.

Functional natural dyeing latex foam prepared according to the manufacturing process as described above is finely processed functional natural material into 1,000 ~ 10,000mesh mixed with water, and ball mill processing the functional natural material mixed with water with a vulcanizing agent and accelerator After adsorbing and liquefying the functional material on the surface of the vulcanizing agent and the accelerator, it is prepared by mixing, foaming and molding the latex stock solution together with a curing agent, an oxidizing agent, an anti-aging agent and a filler, according to the production method of the present invention. In addition to being able to mass-produce foams, it is possible to produce latex foams with a uniform distribution of functional natural materials, excellent color, and clean foaming cells and surfaces.
