A natural rubber toothpaste rubber having a crepe-like unevenness on its surface is known (for example, Utility Model Registration No. 30).
No. 14117).

[0003]

However, in the case of conventional toothpaste rubber, the moldability and workability are not sufficient, and it has been difficult to produce a dog pacifier toy having a freely designed shape.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has an excellent moldability and workability, and can easily produce a natural rubber dog pacifier toy having a free design shape. An object of the present invention is to provide a method for manufacturing a pacifier toy.

[0005]

In order to achieve the above-mentioned object, a method for producing a pacifier toy for dogs according to the present invention comprises:
A low-moisture natural rubber latex of 0% is poured into a mold container having a desired shape, and is vulcanized with hot air to obtain a water 1
0% or less of natural rubber latex for processing of desired shape,
The natural rubber latex for processing is formed into a desired design shape and then hot air vulcanized at 100 to 110 ° C. to produce a dog pacifier toy of a desired shape made of 100% natural rubber. .

It is preferable that a colorant of a desired color and a odorant of a desired odor are added to the liquid low-ammore natural rubber latex.

[0007]

In the method of the present invention, first, a natural rubber latex for processing having a moisture content of 10% is prepared from a raw material of a low rubber natural rubber latex having a dry rubber content of 60% and a moisture content of 40% obtained by concentrating a natural rubber fresh latex. Since the pacifier toy for dogs is molded and vulcanized using the natural rubber latex for processing which is rich in processability and moldability, the pacifier toy for dogs having any shape can be easily produced.

The pacifier toy for dogs obtained by the method of the present invention is made of 100% natural rubber, so it has excellent rebound resilience and elongation, and does not easily become ragged even when the dog bites, and can withstand long-term use. Further, since the elastic shrinkage is large, when the dog's teeth bite, it is immediately closed so as to surround the teeth, so that the action of removing dirt and plaque from the teeth can be enhanced. In addition, it can be made to look beautiful with a coloring agent, and by adding a favorite odor of dogs, for example, beef odor with an odorant,
A pacifier toy that strongly attracts the interest of dogs can be obtained.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a process chart of the method of the present invention. As shown in the figure, the method of the present invention comprises the following steps: (1) a step of producing a liquid low-ammore natural rubber latex composed of 60% of dry rubber and 40% of moisture; (2) a step of producing a natural rubber latex for processing; 3) a forming process of a pacifier toy for a dog. Hereinafter, each of these steps will be described.

(1) Step of Producing Liquid Low Ammore Natural Rubber Latex The starting material in this step is a natural rubber (NR) fresh latex collected from a rubber tree. Table 1 shows the components of the natural rubber fresh latex as this starting material.

[0011]

[Table 1]

The above-mentioned natural rubber fresh latex is a typical colloidal emulsion color liquid similar to milk, and is a so-called hydrophobic colloid sol having a serum as a dispersion medium and a rubber hydrocarbon as a dispersion phase. Fresh latex immediately after being collected from a rubber tree is not simply a colloid sol in which rubber hydrocarbons are dispersed in serum, but a substance called lutoid, which is larger than rubber particles, is dispersed as a dispersed phase. Lutoid is a yellow gelatinous unstable substance that dissolves and stabilizes upon addition of ammonia.

Further, natural rubber fresh latex has too strong a liquidity, and is inconvenient for product processing as it is. Therefore, this is concentrated to obtain a liquid low-ammore natural rubber latex having a dry rubber content of 60% and a water content of 40%.

That is, first, a vulcanizing agent, a vulcanization accelerator, a vulcanization accelerator, an antioxidant, a filler, and the like are added to the above-mentioned natural rubber fresh latex as in the case of general solid rubber. Since latex is a colloidal solution of rubber particles using water as a medium, a dispersant and an emulsifier are added.
In addition, a stabilizer is added to keep the colloidal stability of the latex, and a thickener and a wetting agent are added to make the viscosity easy to process and to adjust the surface tension. Agent, gelling agent and creaming agent for concentration. Further, a colorant and an odorant, for example, a red pigment as a colorant, and a dog's favorite beef odorant as a odorant are added and mixed.

Further, ammonia is added to improve the storage stability of the latex. Usually, about 0.7% of ammonia is usually added. However, this addition amount has a strong irritating odor, hinders the processing work, and is not suitable as a toy for dogs with a developed sense of smell. Therefore, in the case of the present invention, the addition amount of ammonia is set to a low amount of 0.2%, and instead, pentachlorocarbonate or boric acid is added. Such latex is
It is called low ammonia latex (LA latex).

Then, the natural rubber fresh latex to which the above-mentioned chemicals and a coloring agent and an odorant are added and mixed is subjected to hot air vulcanization, and the water contained in the latex is evaporated and vulcanized to obtain a dry rubber content of 60%. A liquid low-ammore natural rubber latex concentrated to a water content of 40% is produced. This concentrated low-ammore natural rubber latex has the following advantages over synthetic rubber latex.

Good storage stability. In particular, it is more stable at low temperatures than synthetic rubber latex. Good film-forming ability. High wet gel strength. High film strength. Large growth. High elasticity.

(2) Process of producing natural rubber latex for processing Next, the above-mentioned liquid low-ammore natural rubber latex concentrated to 60% of dry rubber content and 40% of water is put into a mold container having a desired shape, for example, Inject into a round bar mold,
Hot air vulcanization is carried out for 30 minutes. In this way, moisture is evaporated simultaneously with vulcanization, and a natural rubber latex for processing composed of a square bar 1a or a round bar 1b having a water content of less than 10% as shown in FIGS. 2 (A) and 2 (B) is obtained.

The raw materials in the step (2) are the dry rubber content 60% and the water content 40% obtained in the step (1).
Liquid latex natural rubber latex, which is easily concentrated into a mold or the like. On the other hand, when the vulcanization of the raw material and the evaporation of the water are started and the water content becomes less than 10%, the raw material starts to harden, and the liquid low-ammore natural rubber latex becomes a solid (natural rubber latex for processing) and becomes a mold. Can be easily removed from In addition, since the taken out natural rubber latex for processing is not completely cured and is in a half-life state, it can be molded and processed into a desired shape.

(3) Forming process of dog pacifier toy The natural rubber latex for processing in the semi-limmed state is formed into a desired shape, for example, as shown in FIG. 3B with a jig (not shown) and twisting, or as shown in FIG. 3B, knotting both ends of the round bar of FIG. Processed,
In this molding state, 40 to 5 at 100 to 110 ° C.
Hot air vulcanization is performed again for 0 minutes, and water is completely evaporated at the same time as vulcanization. When this vulcanization is completed, the semi-processed natural rubber latex for processing becomes 100% natural rubber and cures, maintains the molded processing shape as it is, and exhibits strong rebound resilience. 2
Completed as b.

The pacifier toys 2a and 2b for dogs obtained in this manner thereafter maintain the shapes of FIGS. 3A and 3B and again have the original square bar 1a of FIGS. 2A and 2B. It does not return to the round bar 1b. Therefore, a pacifier toy for dogs of various designs can be made using this property.

The specific gravity of the pacifier toy for dog obtained in this manner is about 0.98, so that it floats on the water.
Therefore, it can be safely used for training dogs in water such as rivers, seas and lakes. In addition, natural rubber 10
Since it is 0%, the rebound resilience is extremely large and the rebound is large.
For this reason, when thrown on land or the like, in combination with the design shape and the like, it jumps in an unspecified direction like a rugby ball, which is useful for dog exercise and health maintenance.

[0023]

As described above, according to the method of the present invention, a natural low-moisture natural rubber latex having a dry rubber content of 60% and a water content of 40% obtained by concentrating natural rubber fresh latex is poured into a mold container having a desired shape. Then, by hot air vulcanization, a natural rubber latex for processing of a desired shape having a water content of 10% or less is formed. The natural rubber latex for processing is formed into a desired design shape, and then hot air vulcanized at 100 to 110 ° C. By doing so, a dog pacifier toy made of 100% natural rubber and having a desired shape can be made, so that a dog pacifier toy made of 100% natural rubber and having any shape can be easily made.

Further, by adding and mixing a coloring agent,
Since the desired color can be freely added, the appearance can be beautiful, and by adding and mixing an odorant, it is possible to add a beef odor or the like that the dog likes. Pacifier toys for dogs can be obtained. The pacifier toy for dog obtained by the method of the present invention is composed of 100% of natural rubber.
It has excellent rebound resilience and elongation, does not easily become ragged even if a dog bites it, and withstands long-term use. In addition, since the elastic shrinkage is large, when the dog's teeth bite, the dog is immediately closed so as to surround the teeth, so that the action of removing dirt and plaque from the teeth can be enhanced.
