(1) ocher

The loess is a natural material deposited by convection and weathering, and is called a living energy that breathes to absorb and store solar energy for a long time. The loess is uniform in particle and provides good water permeability as porous. The surface of the particles of ocher has a wide honeycomb structure, and consists of a multilayer structure having numerous spaces. In these sponge-like holes, far-infrared rays are absorbed and stored in a large amount, releasing when heated to stimulate molecular activity of other objects. In addition, loess has excellent detergency, has excellent deodorization, antibacterial, insect repellent, mold growth and dehumidification effect, and has about 2 times the amount of oxygen compared to the amount of oxygen in general air. Can provide. Lastly, the loess contains natural enzymes such as catalase, piphenol oxidase, cyclase protease, and the like, and is known to provide detoxification, degradability, and purification.

The loess is 40 to 90 parts by weight based on 100 parts by weight of the ocher composition, preferably 50 to 70 parts by weight. When the content of the loess is less than 40 parts by weight, it is not possible to obtain a purification, sterilization function and a protective effect, which are inherent functions of the loess, and when it exceeds 90 parts by weight, powdering due to the drying of the ocher composition may be increased, which may lower the stability of the coating film. Not.

(2) electrodeposition

The electrodeposition agent may provide the spreadability and binding strength of the ocher composition. The electrodeposition agent is at least one selected from the group consisting of polyoxy ethylene alkyl acrylic arylether, sodium ligno sulfonate, wheat flour, rice grass and starch powder, preferably polyoxy ethylene Alkyl arylether and sodium lignosulfonate. The electrodeposition agent is included in an amount of 0.01 to 10 parts by weight, preferably 0.01 to 5 parts by weight, based on 100 parts by weight of the ocher composition. When the electrodeposition agent is included in the range, the addition of the ocher composition to the core of the golf ball provides proper spreading to induce uniform mixing and increase the bonding force between the core and the ocher composition to prevent bond breakage due to the blow. .

(3) Solvent

The solvent may induce uniform mixing of ocher and components, and may be added in an appropriate amount to adjust the viscosity, coagulation, etc. of the composition. The solvent may be at least one of distilled water, purified water, rock water, hot spring water and vegetable water, and preferably distilled water. The solvent may be included in an amount of 2 to 50 parts by weight, preferably 25 to 50 parts by weight, based on 100 parts by weight of the ocher composition. When the solvent is included in the above range can provide a suitable viscosity, coagulation, etc. to the composition to induce a stable bond.

(4) fungicides and insect repellents

The ocher composition may further include a fungicide and an insect repellent. When the fungicides and insect repellents are added to the ocher composition, it maximizes the insect repellent and bactericidal effect which is inherent to the ocher, thereby providing more improved insect repellent and bactericidal power and preventing mold growth. The fungicides and insect repellents can be used without limitation as long as it is a component applicable to plants, preferably one of the herbaceous acid, magma cue, herbal oil (lavender, rosemary, lemon rice, lemongrass), citronella extract, naphthalene It may be more than, preferably naphthalene and wood vinegar.

The wood vinegar is a liquid extracted through the cooling device of the smoke generated in the carbonization process of the tree, it is known to be effective in the prevention of pests and the suppression of development. The wood vinegar is one or more selected from the group consisting of conifers, deciduous trees, arbors, shrubs, evergreens, deciduous vegetation leaves, stems, roots, fruits, and flowers, and captures the steam or smoke generated during the pyrolysis process It can be prepared through a process such as cooling, liquefaction, condensation, separation, aging, filtration. The manufacturing process may be applied by appropriately selecting the conditions known in the art, and steam or smoke produced by carbonization by pyrolysis at 150 to 500 ℃ cooled and condensed through a cooling device through the separation and filtration process through wood vinegar solution Can be obtained. The prepared wood vinegar is aged at room temperature for 6 months or more, and may be added to the ocher composition after removing the toxic and harmful substances in the wood vinegar.

The magma cue is an ingredient that can be collected from natural rocks having antibacterial and bactericidal effects, and artificially synthesized and commercially available ones are used. The magmaque is SiO260 ~ 80 wt%, Al2O3 5-15 wt%, Fe2O3 1-5 wt%, CaO 1-5 wt%, Na2O 1-5 wt%, K2O 1-5 wt%, MgO 0.1-1 wt% % And Ag 2 O 0.5 ~ 10% by weight in a glass melting furnace of 1200 ~ 1550 ℃ melted for 19-30 hours, and has a particle size of 20nm to 1000㎛. In addition, it may be used by mixing in an amount of 0.01 to 10% by weight in one or more solvents selected from the group consisting of purified water, rock water, hot spring water and vegetable water to provide antibacterial and bactericidal effects.

The fungicides and insect repellents are included in an amount of 0.01 to 40 parts by weight, preferably 0.1 to 35 parts by weight, based on 100 parts by weight of the ocher composition. If the content of the fungicide and the insect repellent is less than 0.01 parts by weight, it is not possible to obtain the improvement of the sterilization and insect repellent effect, and if it exceeds 40 parts by weight, solubility and coagulation of the ocher composition may be lowered, which is not preferable.

The ocher composition may further include suitable additives according to the desired formulation, and may be, for example, inorganic pigments, natural surfactants (cocobetaines), diatomaceous earth, vegetable oils, and the like. The additive may be included in an amount of 0.01 to 20 parts by weight based on the composition.

In addition, in the present invention, the core of the two-piece golf ball may use a metal salt of α, β-unsaturated carboxylic acid as the co-crosslinking agent, and may further include an organic peroxide as the co-crosslinking initiator.

In the present invention, the metal salt of α, β-unsaturated carboxylic acid used as a co-crosslinking agent in the core of a two-piece golf ball is a monovalent metal salt of α, β-carboxylic acid having 3 to 8 carbon atoms or α, β having 3 to 8 carbon atoms Divalent metal salts of carboxylic acids can be used. Any one or more selected from zinc acrylate, sodium acrylate, zinc methacrylate, and sodium methacrylate may be used as an example of the monovalent or divalent metal salt of α, β-carboxylic acid having 3 to 8 carbon atoms.

The metal salt of α, β-unsaturated carboxylic acid used as the co-crosslinking agent in the present invention can be used 15 to 45 parts by weight, preferably 25 to 35 parts by weight based on 100 parts by weight of the base rubber. If the metal salt of α, β-unsaturated carboxylic acid is less than 15 parts by weight based on 100 parts by weight of the base rubber, the amount of organic peroxide, which is a co-crosslinking initiator, must be increased to obtain a suitable hardness for the golf ball. The distance of the golf ball is reduced. And, when used in excess of 45 parts by weight, the core is too hard, there is a problem that the blow feeling when hitting the golf ball is reduced. Therefore, the core used in the two-piece golf ball of the present invention is preferably added 15 to 45 parts by weight of a metal salt of α, β-unsaturated carboxylic acid, which is a co-crosslinking agent, based on 100 parts by weight of the base rubber.

In the present invention, the co-crosslinking initiator may use an organic peroxide. Examples of such organic peroxides in the present invention include dicumyl peroxide, t-butylcumylperoxide, dibenzoylperoxide, di- (2,4-dichlorobenzoyl) per One or more selected from oxide (Di- (2,4-dichlorobenzoyl) -peroxide) and di-t-butylperoxide may be used.

The core in the present invention may be used 0.2 to 5 parts by weight of the co-crosslinking initiator, preferably 0.5 to 4 parts by weight based on 100 parts by weight of the base rubber. When less than 0.2 part by weight of the co-crosslinking initiator is used with respect to 100 parts by weight of the base rubber in the core of the present invention, the repulsion property of the core of the golf ball decreases and the flying distance is lowered. In order to obtain the content of the co-crosslinking agent must be reduced in this case, the repulsion property is reduced and the flying distance is lowered.

On the other hand, the core in the present invention may contain a predetermined amount of crosslinking aids such as active agents, anti-aging agents, vulcanizing agents, vulcanization accelerators in addition to the base rubber, ocher composition, co-crosslinking agent, co-crosslinking initiator.

As an example of such a crosslinking aid in the present invention, an active agent such as zinc oxide may be added in an amount of 1 to 30 parts by weight, preferably 10 to 25 parts by weight, based on 100 parts by weight of the base rubber. If the zinc oxide is used in an amount exceeding 30 parts by weight, the content of the cross-linking agent must be reduced in order to obtain the proper hardness of the golf ball. If zinc oxide is used in less than 1 part by weight, there is also a problem that the resilience characteristics are reduced.

Crosslinking aids such as anti-aging agents, vulcanizing agents, and vulcanization accelerators mentioned above may be appropriately selected by those skilled in the art and used in predetermined amounts, and detailed descriptions thereof will be omitted since they are not essential components in the present invention. .
