活性炭に使用されている程度であった。2. Description of the Related Art At present, if waste tires and the like are taken to a stable treatment plant, the average fare per ton is about 10,000 yen, and a processing cost of 5,000 yen is collected. . In addition, there is a treatment plant that will not receive if it is not crushed. If it is crushed even if it is rough, it costs about 10,000 yen. These are the causes of illegal dumping due to open storage. On average about 1 even in decent case
Since it costs 5,000 to 20,000 yen / ton, the value on this side must be a standard of the tire grinding cost of the present invention. Conventionally, the size of a tire rubber portion has been gradually reduced from a rough crack and finely divided through several steps. Naturally, the power cost is high and the crushing cost is high. As a result, while the demand decreased, it was only used for high-grade activated carbon that cost only a few hundred thousand yen.

い価格で持ち込む事が出来る利点を持っている。[0003] The low production volume causes high costs, and the biggest drawback of the pulverization method in a factory is that the fare of the product varies depending on the distance from the factory to the place of demand. As mentioned above, crushing on a ship has the advantage that it can be brought anywhere in Japan at a price that does not change much by transporting it to the port nearest the place of demand.

あれば、多くの需要がある。故に、本発明においては、
第一に価格を下げる具体的破砕法、第二に需要の増大の
具体的工法、等を解決しようとするのである。As described in claim 2, there is a great demand for the rubber of the pulverized tire if the price is low. Therefore, in the present invention,
First, it seeks to solve concrete crushing methods that lower prices, and second, concrete construction methods that increase demand.
【０００５】ゴムの定義は明確では無いが、一般には、

ガラス転移以下の状態を、ガラス状態と称している程、
破砕が容易となるのである。[0005] The definition of rubber is not clear, but in general,
It refers to all materials having a small elastic modulus and a large elongation at break. However, this is what makes rubber crushing difficult. However, it is known that the elastic modulus of an amorphous polymer rapidly decreases near the glass transition temperature. The state below this glass transition is called the glass state,
Crushing becomes easier.
【０００６】無定型個体（ゴム質）から過冷却液体状態

４４℃を得る。故に、−５０℃付近を目標に、冷却すれ
ぱ、ゴム質は個体状態になり、容易に破砕する事が出来
る事となる。[0006] The temperature at which a phase transition from an amorphous solid (rubber) to a supercooled liquid state (glassy bear) often occurs at a temperature close to 2/3 of the melting point expressed in absolute temperature (Nikkan Kogyo) (See page 294 of the Science and Engineering Dictionary published by a newspaper company.) As described in claim 1, assuming that the melting point of rubber is 70 ° C.,
(70 + 273) 2/3 ≒ 229,229-273 =-
44 ° C. are obtained. Therefore, when the temperature is reduced to around -50 ° C., the rubber material is in a solid state and can be easily crushed.
【０００７】冷却法には、通常の冷凍機による方法があ

−２０℃程度であって、本発明の目標とする−５０℃を

粉砕費が高くなる原因である。[0007] As a cooling method, there is a method using a normal refrigerator. In a general refrigerator, the obtained temperature is at most,
It is about −20 ° C., and the target of the present invention of −50 ° C. can only be obtained by using liquid nitrogen or the like. This is the cause of high grinding costs.

There are no high places such as the top of the Himalayas, or near the North and South Pole. The present inventor has reported that coal from Australia, which is 8,000 km away, to a Japanese thermal power plant is 3,700 per ton.
Knowing that they brought them around the circle, the transportation cost occupied by them was probably around 1,000 to 2,000 yen per ton, and the South Pole, which was 12,000 to 13,000 km away, Since it is about 1.6 times that of Australia, if the fare is proportional to the distance, it is about 3,0 per ton.
The value of ¥ 00 is the basis of the idea of the present invention.

なる事になり、往復運賃も同様３，０００円であったの
で、８，４００円となる。[0009] It takes about 14 days to operate 12,000 km at a speed of 35 km / h. About 30 round trips
As described above, the date for the 30th day is 3.000 yen. A coal carrier was partially remodeled, a crusher was installed, and 1,000 m
If the magnitude of the tire 2 of the hold came equipped approximately 6,000, as to crush about 200 tires per day, to crush the whole amount, it is necessary approximately 30 days. 30 days is approximately the number of round trip days. If the weight per tire rubber material is 60 kg, 6,000 rubber materials = 360 tons of rubber material will be crushed in about 30 days. Since the sailing seafarer and the crushing worker are the same person, the crushing cost can be considered to be proportional to the number of days as well as the fare. However, when 1,000 tons of coal are tires, the shape is a donut type, so there is a lot of space and the load becomes 360 tons.
3,000 x (1,000 / 360) = 8,400 yen, and the round-trip fare is also 3,000 yen, so it is 8,400 yen.

来る計算となる。A total of 16,800 yen of the above both costs departure from a Japanese port, crushing rubber in Antarctica, and returning to the Japanese port again per ton of rubbery part of the tire. It is the price you have imposed. Earlier, I brought it to the final treatment plant and stated that it was 15,000 to 20,000 yen per ton, but if the rubber crushed by port is available at a slightly equal value, It can be said that this is a very welcome construction method. In order to further reduce the cost, if 125 to 130% of tires are loaded on the outbound route of the transport ship, the return can be safely returned to the port because crushing reduces the bulk. Thanks to this increase in payload,
6,800 yen is a calculation that can be reduced to about 13,000 yen.

Reference numeral 1 in FIG. 2 is a crusher for household waste, and the crushed waste is stored in two bins. Reference numeral 3 denotes a bottle of the crushed rubber (including shredded fibers), and reference numeral 4 denotes a bottle of a flameproofing agent. These are quantified, collected in 11, stirred and sent to 12 kneader cylinders. The cylinder has a heating device inside, and heats it to the required temperature while kneading. The crushed rubber softens, covers the dust and flame retardant particles with rubber, and is extruded from a kneader onto a 13 belt conveyor as a cut plate of appropriate dimensions. This is a resin-based fire-resistant board. The only difference of the cement-based refractory board is that, when mixing with the above-mentioned eleventh mixer, appropriate water is mixed, and there is no need for heating when kneading with the twelve. During the curing period, the resin system is until the temperature drops, and the cement system needs about one month to reach its true strength.

This is because the balance between the demand for products manufactured according to the invention and the amount of waste generated does not match. In extreme cases, the effect of the invention is equal to nothing. In order to prevent the deformation of the tire while the vehicle is running or stopped, the tires were initially made of a cotton weave, but recently nylon, polyethylene and steel wires have been used. In order to pulverize a tire, it is necessary to separate the rubber material from the rubber material. The inventor has designated these as
For separation, a temperature at which a phase transition from an amorphous solid to a supercooled liquid state occurs (a melting point expressed in absolute temperature or a temperature close to (2/3) of the liquidus temperature), that is, a temperature below the glass transition temperature is obtained. I knew that if it was crushed, it could be easily crushed and separated. The melting point of the rubber of the tire is not constant depending on the type and the manufacturer, but if it is 70 ° C on average, its glass transition temperature is about -44 ° C. Therefore-
If the tire is cooled to the target of 50 ° C, it can be easily crushed and separated, and if it is sieved, metals such as nylon fibers and steel wires will remain on the sieve, and the crushed tire rubber Falls under the sieve. Nylon fibers can be chopped, mixed with crushed rubber, and mixed as a material for building materials described later. (Refer to Fig. 1.) In many cases, the cooling method is cooling with a refrigerator. However, the volume of a freezer for crushing a large amount of tires becomes large, and a general refrigerator is usually up to -20 ° C. If it is less than that, equipment funds will be increased, such as using liquid nitrogen. At present, there is no crusher that directly and efficiently crushes rubber at room temperature, so it is necessary to divide the rubber into several stages and apply it to the crusher patiently, and the required power becomes enormous. As a result, the operation cost for crushing becomes expensive, and in terms of the use of the expensive rubber, it is limited to expensive products, and the range of demand is limited. The inventor of the present invention uses a temperature in an extremely cold region as a method of crushing tires at low cost, and lists price values as a method of explanation.However, if price fluctuations and the like are considered, these are a kind of method. It should be considered as an index. 1) Crush in an atmosphere where the temperature of the natural environment is −50 ° C. or less. 2) The current price of coal imported from Australia, which is about 8,000 km or more from Japan, is about 3,700 tons of coal (as of 1999) carried on a 1,000 ton coal ship. Yen / ton. From this, it can be considered that the fare included in this is about 1,000 to 2,000 yen / ton. 3) For example, the distance from Japan to Antarctica is 12,000-
It is about 13,000km, so 8,000 to Australia
It is about 1.6 times km. Therefore, the fare to Antarctica can be calculated at about 3,000 yen. This amount corresponds to the freezer construction cost, freezing cost and crushing cost. 4) 12,000 km requires about 2 weeks at an average speed of about 35 km. 5) The carrier uses a coal carrier, and in one corner of the hold,
If a crushing machine is installed and placed, the berth will be anchored on a suitable sea below -50 ° C and the tires carried by itself will be crushed in this atmosphere. 6) It is a day about 200 pieces of capable of disrupting the tire equipment, if the hold of 1,000m 8 large and small tire is about 6,000 housing can, of about 4 weeks crushing operation It will take days. Since this is about twice as long as a one-way voyage of two weeks, the crushing cost is roughly
It is considered to be about 3,000 yen, the same as the transportation cost. (The crushing work shall be performed by seafarers.) 7) The average weight of rubbery material per tire is approximately 60k.
Assuming g, 6,000 bottles would be 360 tons and 1,000 tons of coal divided by 360 = 2.8. 8) Since a ship carrying 1,000 tons of coal carries 360 tons, the fare per ton of tire rubber is 3,000 ×
2.8 = 8,400 yen, which is equivalent to the processing cost per ton of tire rubber. 9) Eventually, the cost of transporting to Antarctica and grinding the tires is
From a port in Japan until returning to the port, the cost of coal was about 3,700 × 1.6-6.000 yen / ton. The cost is 8 times, the cost of going to Antarctica, crushing and returning to the Japanese port again is about (3,000 + 3,000) × 2.
8 = 16,800 yen. What is claimed in claim 1 is that an article is transported to, for example, a frigid South Pole, frozen using the temperature of the frigid area, and the frozen article is processed in the frigid area. And a freezing method that can be processed at low cost.

Recycling methods include the following. 1) Manufacture of high-grade activated carbon (it has existed conventionally, but if the production cost of fine-grained rubber is reduced, its use will be expanded) 2) Use as fuel (injected into a kiln as tires and burned There was a factory, but if it could be pulverized at low cost, the demand for fuel would likely increase.) 3) The trade name “Thomas fireproof board” developed by the present inventors
(Cement-based artificial wood composition-Patent No. 26
No. 11500, composition for flame-retardant board-Patent No. 265
9521, and a composition for flame-retardant artificial wood using waste paper as a raw material-used for a part or all of aggregates such as Patent No. 2647632). It can be broadly classified into a board made of a cement-based solidifying agent and a board made of a resin-based binder. The pulverized rubber can be used as an aggregate of a building material and also as a binder when the price becomes low. Rubber is lighter than other general aggregates and has poor thermal conductivity and poor sound transmission, so it is possible to manufacture special boards such as sound-absorbing boards, shock-absorbing materials, and heat-insulating boards. Many applications await, such as partitioning of houses, sound insulation boards on highways, and the like. 4) Utilization of the present inventor's patent “Cementitious composition for pavement surface layer” Patent No. 2531897 as a surface pavement material for roads, or “Method and apparatus for sterilizing medical waste”
This is a construction method in which a rubber material is dissolved by applying a heat source such as Japanese Patent No. 2659462 and used for abrasion-resistant surface pavement. Of the above, 1) and 2) do not require special mention because they are existing technologies, but 3) and 4) add the crushed rubber as an aggregate to the patents already submitted. Alternatively, a method as a heat source for softening and kneading a new binder agent and a binder is defined as claim 2.
