Description
METHOD OF MANUFACTURING MOLD
PRODUCTS WITH UNUSABLE TIRES
FIELD OF THE INVENTION
The present invention relates to a reproduction process of lmlls:~hle tires and, more particularly, to the m~nnf~rt~lring method of the various mold products with different properties from a mixture of pulverized tire, resins and rhemi~l.s. This compounded row-material can be turned into a desired product after the catapulting, extruding, and pressing process.
BACKGROUND OF THE INVENTION
Car industry is globaly recognized as the most productive and fastest growing industry in this modern society. The cars, the most useful and essential aid to m~nkind, can offer convenient transportation, and are closely related to people's everyday lives. Especially in the society, which requires frequent traveling, people can not even think about m~i~";l;"i~ their everyday lives without the cars. But as the car production grows rapidly, the ~llv~u-l~llent~l pollution caused by the cars has raised serious problems to us.
Along with the ~llvirorll-l~nt~l pollution caused by the cars, such as air pollution from the toxic gas or ~h~n(loned cars on streets, disposing of the used tires is also one of the serious ~nvilolllllent~l pollutions. There have been many efforts to recycle the tires preventing ~ vi~ Pnt~l pollllt;on and lltili~ing the valuable energy resource. But unfortunately, the tires have 2130~76 been made into only few types of products, and the portion of the recycled tires is so small compared to the mass-produced tires; The tires are cut into narrow pieces and made into ropes or rubber baskets. Except for the recycling process above, most of the tires are burned up to ashes in incine dlols.
But also burning the tires not only causes air pollution from toxic gas, but wastes valuable resources which we can recycle into a row-material to make various products instead.
Furthermore, buring tires is now prohibited by law and, as a result, we are facing the new problem of recycling the enormous amount of the mass-produced tires. If we can transfer the tires into valuable resources, it can prevent environment~l pollution and save energy. With the present invention, this can be possible with the mixture of the pulveriæd tires, resins and chPmic~l.s. The present invention is surely a break-through to reduce the pollution, conserve the precious energy, and finally contribute to the development of the nation's industry.
Trying to find the - solution of the- problems above, the inventor invested large amount of finance in the research of the recycling techique of the tires, and finally has come to develop the reformable row-material which can be applied in many different areas of our industries.
SUMMARY OF THE INVENTION
It is an object of the present invention to recycle the used tires into useful resources.
It is another object of the present invention to pl~:ve 2130~7G
~llvilo~ ent~l pollution from the burning tires and the loss of energy.
It is further object of the present invention to provide methods of manllf~rtl1ring the various kind of mold products which can satisfy many different requir~ments such as a smooth surface, a strong structure, an elegant appearance and so on.
A method of manllf~ctllring mold products with lml1.s~hle tires according to the present illv~lllion includes the steps of mixing pulverized tire, one or more resins selected from the group of polyl.rol~ylene, low density polyethylene and high density polyethylene and one or more ~h~mic~ks select~l from the group of acetone, caustic soda, glass wool, ammonium phosphate, starch and pigments; melting the mixture at 230C to 350C; and molding by the catapulting, extruding and pressing process.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the present invention, the size of the pulverized tire' s particles is not sperific~lly stated. Therefore, the tires can be crushed into suitable sized particles according to the purpose of the targeted products. The proportion of the pulverized tires in the mixture is not specified, but it is desirable to use 15 to 90 weight percent of the mixture. To crush the tires into fine particles, the frozen crush technique with the liquid nitrogen can be more effectively used.
Used or scrapped resins of each kind can replace the above resins such as polypl ~pylene resin, low density polyethylene resin and high density polyethylene resin and the cont.~ of the 21~3~7~
above resins are respectively desirably under 50 weight percent of the composition. Nylon, polyester or other synthPtic resins can be added or applied to replace the above resins.
One or more chemic~ls among acetone, caustic soda, glass wool, ammonium phosphate, starch and pigments are used according to the purpose of the targeted products. For example, to make the smooth surfaced and strong products such as construction board, street bricks and boxes, the acetone, caustic soda, glass wool, ammonium phosphate, starch, and pigmentS are employed. To make water-purifier-tanks, irrigation pipes and sewer pipes, acetone, glass wool, ammonium phosphate and starch are employed. For the application of the flPxihle panels, buckets and washbasins, caustic soda, glass wool, ammonium phosphate and starch are applied. In case of the products with elasticity and high strength such as merli~n strip in highways, acetone, caustic soda, glass wool, starch, and some pigments are mixed with the pulverized tire. For the breakwater in seashores, acetone is used. For the product requiring high hardness and tensile strength such as a embankmPnt to prevent the l~nrl~lirling and palettes, glass wool, ammonium phosphate, starch and pigments are used. For the interior finish work such as bricks and set building frame which requires good hardness, class wool, acetone, ammonium phosphate and pi~mentS are needed.
It is difficult to limit the exact weight l.r()~ol Lion of each ~hPmi~ls in the mixture, but it is desirable to use a~ xi~ t~ly under the 0.5 weight % of the acetone, 0.5 weight % of the c~lstic soda, 30 weight % of the glass wooL
213087fi 5 weight % of the ammonium phosphate, and 15 weight % of the starch.
The acetone is used as the solvent, and if more than 5 weight % of the weight content is supplied, this can lower the quality of the product caused by the oversuppling of the solvent.
The caustic soda makes many fine bubbles in the ~ixture to increase the shock absorbing capability and elasticity of the product. Oversuppling of the caustic soda (more than 0.5%) can cause too many bubbles in the product and lower the quality of the product too. The glass wool increases the thermal resistance of the product, but over-suppling causes inferior quality of the product, and it results in difficult, molding process of the product. The ammonium phosphate increases the fire-re.sist~nce of the product.

PRODUCTS WITH UNUSABLE TIRES
FIELD OF THE INVENTION
The present invention relates to a reproduction process of lmlls:~hle tires and, more particularly, to the m~nnf~rt~lring method of the various mold products with different properties from a mixture of pulverized tire, resins and rhemi~l.s. This compounded row-material can be turned into a desired product after the catapulting, extruding, and pressing process.
BACKGROUND OF THE INVENTION
Car industry is globaly recognized as the most productive and fastest growing industry in this modern society. The cars, the most useful and essential aid to m~nkind, can offer convenient transportation, and are closely related to people's everyday lives. Especially in the society, which requires frequent traveling, people can not even think about m~i~";l;"i~ their everyday lives without the cars. But as the car production grows rapidly, the ~llv~u-l~llent~l pollution caused by the cars has raised serious problems to us.
Along with the ~llvirorll-l~nt~l pollution caused by the cars, such as air pollution from the toxic gas or ~h~n(loned cars on streets, disposing of the used tires is also one of the serious ~nvilolllllent~l pollutions. There have been many efforts to recycle the tires preventing ~ vi~ Pnt~l pollllt;on and lltili~ing the valuable energy resource. But unfortunately, the tires have 2130~76 been made into only few types of products, and the portion of the recycled tires is so small compared to the mass-produced tires; The tires are cut into narrow pieces and made into ropes or rubber baskets. Except for the recycling process above, most of the tires are burned up to ashes in incine dlols.
But also burning the tires not only causes air pollution from toxic gas, but wastes valuable resources which we can recycle into a row-material to make various products instead.
Furthermore, buring tires is now prohibited by law and, as a result, we are facing the new problem of recycling the enormous amount of the mass-produced tires. If we can transfer the tires into valuable resources, it can prevent environment~l pollution and save energy. With the present invention, this can be possible with the mixture of the pulveriæd tires, resins and chPmic~l.s. The present invention is surely a break-through to reduce the pollution, conserve the precious energy, and finally contribute to the development of the nation's industry.
Trying to find the - solution of the- problems above, the inventor invested large amount of finance in the research of the recycling techique of the tires, and finally has come to develop the reformable row-material which can be applied in many different areas of our industries.
SUMMARY OF THE INVENTION
It is an object of the present invention to recycle the used tires into useful resources.
It is another object of the present invention to pl~:ve 2130~7G
~llvilo~ ent~l pollution from the burning tires and the loss of energy.
It is further object of the present invention to provide methods of manllf~rtl1ring the various kind of mold products which can satisfy many different requir~ments such as a smooth surface, a strong structure, an elegant appearance and so on.
A method of manllf~ctllring mold products with lml1.s~hle tires according to the present illv~lllion includes the steps of mixing pulverized tire, one or more resins selected from the group of polyl.rol~ylene, low density polyethylene and high density polyethylene and one or more ~h~mic~ks select~l from the group of acetone, caustic soda, glass wool, ammonium phosphate, starch and pigments; melting the mixture at 230C to 350C; and molding by the catapulting, extruding and pressing process.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the present invention, the size of the pulverized tire' s particles is not sperific~lly stated. Therefore, the tires can be crushed into suitable sized particles according to the purpose of the targeted products. The proportion of the pulverized tires in the mixture is not specified, but it is desirable to use 15 to 90 weight percent of the mixture. To crush the tires into fine particles, the frozen crush technique with the liquid nitrogen can be more effectively used.
Used or scrapped resins of each kind can replace the above resins such as polypl ~pylene resin, low density polyethylene resin and high density polyethylene resin and the cont.~ of the 21~3~7~
above resins are respectively desirably under 50 weight percent of the composition. Nylon, polyester or other synthPtic resins can be added or applied to replace the above resins.
One or more chemic~ls among acetone, caustic soda, glass wool, ammonium phosphate, starch and pigments are used according to the purpose of the targeted products. For example, to make the smooth surfaced and strong products such as construction board, street bricks and boxes, the acetone, caustic soda, glass wool, ammonium phosphate, starch, and pigmentS are employed. To make water-purifier-tanks, irrigation pipes and sewer pipes, acetone, glass wool, ammonium phosphate and starch are employed. For the application of the flPxihle panels, buckets and washbasins, caustic soda, glass wool, ammonium phosphate and starch are applied. In case of the products with elasticity and high strength such as merli~n strip in highways, acetone, caustic soda, glass wool, starch, and some pigments are mixed with the pulverized tire. For the breakwater in seashores, acetone is used. For the product requiring high hardness and tensile strength such as a embankmPnt to prevent the l~nrl~lirling and palettes, glass wool, ammonium phosphate, starch and pigments are used. For the interior finish work such as bricks and set building frame which requires good hardness, class wool, acetone, ammonium phosphate and pi~mentS are needed.
It is difficult to limit the exact weight l.r()~ol Lion of each ~hPmi~ls in the mixture, but it is desirable to use a~ xi~ t~ly under the 0.5 weight % of the acetone, 0.5 weight % of the c~lstic soda, 30 weight % of the glass wooL
213087fi 5 weight % of the ammonium phosphate, and 15 weight % of the starch.
The acetone is used as the solvent, and if more than 5 weight % of the weight content is supplied, this can lower the quality of the product caused by the oversuppling of the solvent.
The caustic soda makes many fine bubbles in the ~ixture to increase the shock absorbing capability and elasticity of the product. Oversuppling of the caustic soda (more than 0.5%) can cause too many bubbles in the product and lower the quality of the product too. The glass wool increases the thermal resistance of the product, but over-suppling causes inferior quality of the product, and it results in difficult, molding process of the product. The ammonium phosphate increases the fire-re.sist~nce of the product.
