Abstract

PURPOSE:To improve the anti-brittleness as product and assist deterioration by mixing the finely pulverized organic material into the finely pulverized inorganic material and mixing a hydrophilic adhesive and sufficiently kneading said material at the normal or high temperature and pressing said material in a tee-shaped metal mold and then demounting the mold by air pressure, etc., and drying the product. CONSTITUTION:60wt. parts of the minutely pulverized inorganic material and at most 60wt. parts of the minutely pulverized dry organic material are mixed and pulverized, and an aqueous solution containing a hydrophilic adhesive in 0.1-3.0% is mixed in at most the wt. parts of the raw material. The minutely pulverized raw material facilitates mixing in kneading and increases the viscosity of the inorganic material by the hydrophilic adhesive containing aqueous solution, and plasticization is facilitated. Further, product can be solidified by the hydrophilic adhesive, and the strength is increased at the same time, and further the tee as product is easily deteriorated even if thrown away in a golf course, and no trouble is generated.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a golf tee, and particularly to a golf tee that is plastic, easy to mold, inexpensively formed, brittle and weatherable. It is about a tee.

[Conventional technology]

It goes without saying that a golf tee is an indispensable item for modern golf. Therefore, there are a large number of applications related to this. However, many of these applications use plastic as a raw material, and many applications claim that form.

As the popularity of golf increases these days, the plastic golf tees that are used all the time are thrown away on golf courses and grounds, causing various problems. For example, we often hear of the danger of patiently picking up discarded tees, which can sometimes lead to damage such as being pierced by tees left underground. Therefore, it is desired to improve the material of golf tees as described above, and many applications have been filed in response to this demand.

Below, we will describe applications that attempt to meet such demands.

(a) Utility Model Application No. 59-102073 The gist of the present invention is that it is a tee made of a compression molded body of sawdust.

Although the shape of the tee can be seen from the drawings, the manufacturing method is not known in detail; however, although the inventor tried, it was difficult to compression mold only sawdust.

(B) Japanese Utility Model Application No. 60-73503 The gist of the present invention is that the ball mounting portion, the tip portion for the tear twig, and the support portion connecting the two are made of solid fertilizer.

The manufacturing method is not known in detail, but the technology to solidify the fertilizer in each part of the tee is thought to be quite difficult.

(c) Utility Application No. 62-186765 The gist of the present invention is as follows.

(i) It is characterized in that it is molded using an inorganic material powder as a raw material that is harmless or beneficial to soil and has a molding property of hardening when mixed with water.

(ii) The raw material is a powder of an organic substance consisting of fertilizer.

Although the composition of the raw materials used in the present application is not clear, it is questionable whether brittle-resistant products can be obtained using only raw materials consisting of soil or fertilizer organic substances.

(d) Utility Application No. 188870/1988 The gist of the present invention is as follows.

(1) Even if the receiver is strong enough to hold a ball during use, it will collect rainwater after use.

11 It is characterized by solid molding using a granular material such as soil so that it weathers quickly when exposed to light.

(ii) The tee is characterized in that a chemical such as an insecticide or an additive such as a fertilizer is mixed into the tee.

(iii) It is characterized in that the tee is formed using a chemical such as an insecticide or an additive such as a fertilizer.

It is presumed that even if the material obtained by kneading soil and water, which are the main raw materials of the present invention, hardens, only a material with weak brittle resistance will be obtained.

(e) Utility Application No. 1987-78955 The gist of the present invention is to mix and knead a synthetic resin adhesive with wood fibers, fine powder, etc., and then put the mixture into a mold and pressurize it to form the rear arm under heat. The golf tee is manufactured by molding and drying.

Since it is difficult to obtain plasticity using only the fiber or its powder used in the present invention even under considerable pressure even when an adhesive is added, it is possible to heat-form it in individual molds, but this method does not improve productivity. There may be a problem.

Based on the above-mentioned application examples, it is not considered that the selection of raw materials for manufacturing golf tees that are different from conventional plastic golf tees, the manufacturing method, the strength of the product, the degree of weathering when left in a tank after use, etc. are sufficient. .

[Problem to be solved by the invention]

Although various compositions and manufacturing methods have been proposed for golf tees as described in 1., the inventor believes that the raw materials for golf tees are inexpensive, and that the material especially kneaded during the manufacturing process has plasticity and metal. It is easy to mold with a mold, the resulting product has considerable hardness and brittleness resistance, and the surface of the product is smooth.Furthermore, even if it is abandoned at a golf course after use, it will be easily weathered on the golf course or ground and will not be damaged later. It is preferable to leave no residue behind.

[Means to solve the problem]

As a result of various studies for the above-mentioned reasons, the inventor mixed microscopically shaped organic material with microscopically shaped inorganic material as the raw material of the present invention, mixed a hydrophilic adhesive therein, and heated it at room temperature or heated. The product is obtained by thoroughly kneading the mixture, pressing it into a tee-shaped mold, removing the mold using air pressure, etc., and drying it.

[Effect]

In the present invention, the raw material pulverized as described above is easily mixed during kneading, and at the same time, the inorganic material increases in viscosity and is easily plasticized by the aqueous solution containing the hydrophilic adhesive. Moreover, this hydrophilic adhesive increases the strength (brittle resistance) of the product as it hardens, and even if the product tee is abandoned on a golf course, it will easily weather and leave no damage.

〔Example〕

The gist of the production of the present invention is as follows.

Finely powdered inorganic and organic materials are thoroughly mixed, an aqueous solution containing the required hydrophilic adhesive is added to this, the mixture is thoroughly kneaded at room temperature or heated, and the mixture is pressed and molded into a tee-shaped mold. This is a golf tee obtained by drying the demolded product.

This will be explained in detail below.

The inorganic raw materials are kaolin, acid clay, diatom] and commercially available clay. Among these inorganic materials, kaolin is the whitest product, while diatomaceous earth and clay are yellowish brown in color. However, when an aqueous solution such as that of the present invention is added to these, there is little difference in viscosity, but there is almost no difference in plasticity.

That is, extrusion is possible.

Regarding organic materials, there are also powdered starch, grain flour (1-wheat, 1-maize, wheat), and 2 types of cortical parts (bran).

This includes bran, tofu lees) and wood flour (sawdust).

Needless to say, it is desirable to use low-cost organic materials or materials that are similar to waste materials. As shown below, starch has a white finish and the kneaded product has good plasticity.

These starches, corn flour, and wheat flour are 1f
Among these, adlay flour was inexpensive and had good Ill plasticity as well. Although bran and bran are completely treated as waste, products with good plasticity were obtained.

The plasticity of the kneaded product is poor, perhaps because the tofu lees and wood flour are powdered and charred, but if the mixture is slightly warmed and kneaded during mixing, the plasticity gradually improves. The most anticipated feature is the low cost and wide variety of products.

The organic material is an inorganic binder and contributes to the strength of the product. In addition, it is desired that if the tea is weathered after use, it will contribute to the soil effect. However, if an excessive amount of organic material is used, the plasticity deteriorates even after kneading. For example, if more than 40% of wood flour is mixed in, the kneaded product will lose its plasticity, and it will be necessary to press it strongly for molding or to gradually increase the amount of adhesive.

This is the main reason why the present invention sets the content of organic materials to 50'% at maximum.

Next, as hydrophilic adhesives, gelatin, modified starch, C
MC, methyl cellulose, polyvinyl acetate emulsion, polymethacrylate emulsion or rubber latex are used. An aqueous solution containing 0.1 to 3% of these is used in an amount equal to or greater than the weight of the above raw materials.

As the above-mentioned adhesive, gelatin and modified starch have weak adhesive properties unless they are used in larger amounts than other adhesives, so varnish 1-
Becomes high.

CMC and methylcellulose (slightly resistant to water) are considered to have the same adhesive properties, but the latter is more expensive than CMC and is therefore considered unsuitable for industrial use.

Both polyvinyl acetate emulsion and polyacrylic ester emulsion have good adhesive strength, but the latter is more expensive than the former. Furthermore, although natural rubber latex was used as the rubber latex, very good results were not obtained. However, since various synthetic rubber latexes will be commercially available in the future, there is still room for consideration. The adhesive described above provides mutual adhesion between raw materials and plasticity during kneading, and also contributes to the strength (brittle resistance) of the resulting product, and promotes disintegration when exposed to rainwater after use.

Further, the strength of the product can be strengthened by increasing the amount of adhesive, but considering the cost and strength of the product, the amount of 1f added to the raw material was set at 0.1 to 3.0%.

Next, the manufacturing process according to the present invention is as follows: 1. Thoroughly mix the two pulverized raw materials, add the aqueous solution containing the above-mentioned hydrophilic adhesive in an amount equal to or more than the amount of both raw materials, and then Alternatively, after heating and kneading well to obtain extrudable plasticity, the product is compressed into a tee-shaped mold, removed from the mold with pressurized air, etc., and dried at room temperature or low temperature to form a product.

Next, an experimental example will be shown.

(i) 10 parts by weight of an aqueous solution containing 13% polyvinyl acetate ester emulsion was added to a mixture of 6 parts by weight of acid clay and 5 parts by weight of starch (commercially available), and the mixture was further thoroughly mixed and kneaded. The product was molded by pressing it into a tee-shaped mold using an extruder, then removed from the mold with compressed air, and dried at low temperatures.The product was pure white and strong enough to be easily pushed into the ground. Furthermore, when this product was soaked in water, it disintegrated in less than 10 minutes.

(ii) 6 parts by weight of kaolin and 5 parts by weight of adlay flour (commercially available)
9 parts by weight of an aqueous solution containing 0.2% CMC were added to a mixture of 9 parts by weight and sufficiently kneaded, and the mixture was pressed into a T-shaped mold using an extruder as in the above example, and the mold was removed and dried at room temperature. Although the product was a little pale and dark in color, it had sufficient hardness and strength.

(ni) 6 parts by weight of acidic clay and 5 parts of bran (commercially available product); 1 [
9 of an aqueous solution containing 0.2% CMC.
After adding part by weight and sufficiently kneading, the product was extruded as described above, molded, demolded, and dried at low temperature. Although the product was pale dark in color, it had sufficient hardness and strength. Also, when soaked in water, it disintegrated within 10 to 15 minutes.

(iv > 10 parts by weight of an aqueous solution containing 52% CMC was added to a mixture of 6 parts by weight of acid clay, 4 parts of wood flour (commercially available) and 4 electric resistance stitches thoroughly mixed in a mortar, and thoroughly kneaded while heating. The product was extruded, molded, and removed from the mold and dried.The product was pale dark in color and seemed to be sufficiently hard, but its strength was slightly reduced (but so far, it had been obtained with sufficient strength).

〔Effect of the invention〕

The golf tee manufactured according to the present invention has considerable hardness and strength (brittle resistance), and can be driven into rough terrain. Furthermore, as mentioned above, it is possible to mass produce it, and the raw materials are plentiful and inexpensive, and even if it is abandoned at a golf course after use, it will be easily weathered by rainwater and will not leave any damage. I look forward to using crystal in the future.
