Hereinafter, the present invention will be described in more detail.

Latex

According to the invention,

The main component, latex, includes acrylic polymers, acrylic copolymers, styrene-acrylic copolymers or blends thereof. Acrylic polymers contain only one type of acrylate monomer, while acrylic copolymers comprise two or more different types of acrylate monomers. The styrene-acrylic copolymer comprises at least one type of styrene monomer and at least one type of acrylate monomer. Representative examples of acrylate monomers are, for example, acrylic acid, butyl acrylate, ethyl acrylate, methyl acrylate, 2-ethyl hexyl acrylate, acrylonitrile, acrylamide, methacrylic acid, methyl methacrylate, ethyl meta Methacrylate, butyl methacrylate, methacrylamide and the like. Examples of styrene monomers include styrene, alpha-methyl styrene and the like.

Examples of suitable acrylic latexes include, for example, DURAPLUS 2 or DuraPlus 2, modified acrylic floor polish or ROSHIELD 3275 acrylic emulsion, available from Rohm and Haas, Philadelphia, Pennsylvania, USA. This includes.

Examples of other commercially available acrylic polymers or copolymers include MEGATRAN 240, MegaTran 228 or SYNTRAN 1921 from Interpolymer, Canton, Mass., In particular elongation and tensile strength. The good SYSTRAN 1921 is useful.

blowing agent

The blowing agent having a KB value of 11 to 15 is preferably 3 to 7 parts by weight, more preferably 4 to 6 parts by weight based on 100 parts by weight of the latex. If it is less than 3 parts by weight with respect to 100 parts by weight of the latex, the foam may not be sufficiently foamed and the shock absorbing force and the restoring force may be lowered. If the content is greater than 7 parts by weight, the foam may be over-foamed to lower the physical properties such as tensile strength and elongation. It is not desirable.

The blowing agent preferably uses a blowing agent having a KB value in the range of 11 to 15, as measured by ASTM D-1133. The blowing agent can be selected from known blowing agents and is used alone or as a mixture to reduce the time required for penetration and also to make substantially spherical foam particles.

Blowing agents that can be used in the present invention include aliphatic hydrocarbons such as propane, propylene, butane, butene, pentane, pentene, hexane, hexene, heptane and the like; Alicyclic hydrocarbons such as cyclobutane, cyclopentane, cyclohexane and the like; Halogenated hydrocarbons such as trichlorofluoromethane, dichlorothifluoromethane, trichlorotrifluoroethane, dichlorotetrafluoroethane, monochlorothifluoromethane, metalchloride, methylene chloride, ethyl chloride, ethylene chloride and the like . The blowing agent may be used alone or as a mixture of two or more so as to have a KB value within the above-mentioned range.

Typical blowing agents used advantageously in the present invention are dichlorotetrafluoroethane (KB value 12).

Vulcanizing agent

The vulcanizing agent is preferably 0.1 to 1 parts by weight, more preferably 0.4 to 0.6 parts by weight based on 100 parts by weight of the latex. If it is less than 0.1 part by weight based on 100 parts by weight of latex, the main raw materials may not be sufficiently crosslinked, and thus the tensile strength and abrasion resistance may not be improved. If the content is greater than 1 part by weight, the impact absorbing force and the restoring force may be lowered. There is a concern, which is not preferable.

Although the vulcanizing agent is not particularly limited, sulfur vulcanizing agents, quinoid vulcanizing agents, methylphenol resin vulcanizing agents and alkylphenol disulfide vulcanizing agents are useful, and triazine thiol vulcanizing agents and thiourea vulcanizing agents are useful. And amine-based vulcanizing agents. These vulcanizing agents may typically be added to the latex during kneading or premixed to the latex which is dynamically vulcanized.

Petroleum resin

The petroleum resin may be included in an amount of 0.5 to 1.5 parts by weight based on 100 parts by weight of the latex as necessary to improve processability.

The petroleum resin may be used alone or as a mixture of two or more of the C5 oil petroleum resin, the C9 oil petroleum resin and the DCPD petroleum resin.

Typical petroleum resins advantageously used in the present invention are C5 oil-based petroleum resins.

incense

The fragrance may be further included in an amount of 0.001 to 0.01 parts by weight based on 100 parts by weight of the latex.

The aroma is not particularly limited, but preferably lavender, jasmine, freesia, peppermint, lemon, acacia, orange, rose, melon, apple, grape, lilac, pine, strawberry, chanel, quince, coffee, lime, chocolate, cocoa, Sunflower, vanilla, pineapple, rosemary flavor may be used alone or in combination of two or more.

Charcoal and Jade Powder

Charcoal powder and jade powder may be further included in an amount of 1 to 5 parts by weight and 0.5 to 1.5 parts by weight based on 100 parts by weight of the latex, respectively.

When charcoal powder is embedded in the pad, since the efficacy of the charcoal may be transmitted to the user's body while the user wears the pad-based product to protect the health, 1 to 5 parts by weight of the latex may be used, if necessary. Charcoal flour may be included.

Charcoal flour may be used alone or as a mixture of two or more among bamboo charcoal, oak charcoal, and wood charcoal.

Typical charcoal flour that is advantageously used in the present invention is oak charcoal flour.

When the jade powder is embedded in the pad, when the product using the pad is worn, the fine particles of the jade-containing bio ceramics create an air vent so that sweat is discharged smoothly to prevent rashes and dermatitis, and the radiation from the bio ceramics. The far-infrared rays are activated by metabolism, and thus may contribute to health promotion. If necessary, 1 to 5 parts by weight of jade powder may be included with respect to 100 parts by weight of latex.

Magnetic powder

When the magnetic powder is embedded in the pad, it can help vitality and healing power (immune and various hormone secretion) to the acupuncture points existing in the human body, thereby contributing to the maintenance of health. May be included.

The present invention having the above configuration is light and easy to process unlike rubber or polyurethane materials, and by limiting the composition ratio of each component, the physical properties such as elasticity, breathability, elastic modulus and tensile strength are good, and excellent moldability and mechanical properties, It is an advantage that the workability is good because it is possible to continuously form the pad by press working on a sheet in a flat state.

In addition, a mixing step of mixing the composition for the pad, an injection step of injecting the pad composition into the mold mold, after the injection step, a molding step of molding the composition for the pad, a demoulding step of removing the mold mold from the molded pad, molded It is a pad manufacturing method that can reduce the working time, cost, etc. by simplifying the slice step to cut the pad into the desired shape.

Hereinafter, the structure of this invention is demonstrated concretely by an Example.
