1 METHOD OF MANUFACTURING MOLD PRODUCTS WITH UNUSABLE TIRES
FIELD OF THE INVENTION
1 2287710 The present invention relates to a reproduction process of unusable tires and, more particularly, to the manufacturing method of the various mold products with different properties from a mixture of pulverized tire, resins and chemicals. 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 mankind, 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 maintaining their everyday lives without the cars. But as the car production grows rapidly, the environmental pollution caused by the cars has raised serious problems to us.
4 Along with the environmental pollution caused by the cars, such as air pollution from the toxic gas or abandoned cars on streets, disposing of the used tires is also one of the serious environmental pollutions. There have been many efforts to recycle the tires preventing environmental pollution and utilizing the valuable energy resource. But unfortunately, the tires have 2, 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 incinerators. 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 environmental pollution and save energy. With the present invention, this can be possible with the mixture of the pulverized tires, resins and chemicals. 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 rowmaterial which can be applied in many different areas of our industries.
SUIfivLARY OF THE EWENTION 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 prevent 4 v 0 3 environmental pollution from the burning tires and the loss of energy.
It is further object of the present invention to provide methods of manufacturing the various kind of mold products which can satisfy many different requirements such as a smooth surface, a strong structure, an elegant appearance and so on.
A method of manufacturing mold products with unusable tires according to the present invention includes the steps of mixing pulverized tire, one or more resins selected from the group of polypropylene, low density polyethylene and high density polyethylene and one or more chemicals selected from the group of acetone, caustic soda, glass wool, ammonium phosphate, starch and pigments; melting the mixture at 2301C to 3501C and molding by the catapulting, extruding and pressing process.
DESCRIPTION OF THE PREFERRED EMBODWENTS
In the present invention, the size of the pulverized tire's particles is not specifically 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 ldnd can replace the above resins such as polypropylene resin, low density polyethylene resin and high density polyethylene resin and the contents of the t above resins are respectively desirably under 50 weight percent of the composition. Nylon, polyester or other synthetic resins can be added or applied to replace the above resins.
One or more chemicals 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 flexible 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 median 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 embankment to prevent the landsliding 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, 1 acetone, ammonium phosphate and pigments are needed.
It is difficult to limit the exact weight proportion of each chemicals in the mixture, but it is desirable to use approximately under the 0.5 weight of the acetone, 0.5 weight % of the caustic soda, 30 weight % of the glass wool, j 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 mixture 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-resistance of the product.
The present invention is illustrated by way of the following Examples, in which all percents are by weight unless otherwise specified.
