Abstract

PROBLEM TO BE SOLVED: To produce a lightweight, elastic, shock-resistant and vibration-proof gravel-like base material which is produced by grinding waste plastics, mixing the ground waste plastics with sand and forming the mixture into a gravel-like material, or forming the ground waste plastics into such a gravel-like material with crushed stone or small stone pieces as nuclei, and mixing the resulting gravel-like material into concrete to prevent floatation of any waste plastic having low specific gravity when used, in order to prevent harmful gases from being generated in the incineration treatment of waste such as waste plastics or waste tires. SOLUTION: The production process of this base material comprises the steps of: grinding waste plastics or waste tires into fine particles; adding sand to the fine particles to obtain a mixture; forming the mixture into a gravel-like material with an injection molding machine; and mixing the gravel-like material into concrete. Optionally, this gravel-like material may be formed by receiving crushed stone in a heat-resistant vessel, or the like, blowing the above fine particles of waste plastics, or the like together with hot air into the heat-resistant vessel, or the like, rotating the crushed stone with the hot air, depositing the fused waste plastics, or the like on the crushed stone and cooling the resulting material by switching the blowing air from the hot air to ordinary air.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a gravel using crushed stones, small gravel, etc. as a core, grinding waste plastics, waste tires, etc., to reduce the specific gravity, and to prevent the floating of plastics. Is mixed with the specific gravity to add the same specific gravity, and when poured into the formwork, sand, waste plastic,
Pulverize and mix waste tires, etc., depending on injection molding machines, or
Put hot air and crushed granules of waste plastic in a heat-resistant container, form a gravel, mix an impact-resistant base material when forming concrete, and use it for concrete base material. The present invention relates to a base material for preventing generation of harmful gas due to the base material.

[0002]

2. Description of the Related Art In order to form concrete having light elasticity and impact resistance, there are foamed concrete and the like, which are mixed with a foaming agent and solidified.

[0003]

The purpose of the present invention is to prevent the release of harmful gas into the atmosphere and to make effective use of resources by incinerating waste plastics, and to crush waste plastics and waste tires. Mix fine granules and sand to form a gravel, form with an injection molding machine and solidify, or blow small gravel crushed stones, etc., together with hot air into a heat-resistant container, etc. to form a gravel shape Or by other methods, formed to fit the cement well, sealed in concrete to increase strength, and added sand to the cement for the purpose of adding elasticity and impact resistance Same as specific gravity, low specific gravity,
In order to prevent the floating of waste plastic, mix the gravel-shaped base material into concrete and use it to prevent the generation of harmful gas when incinerating waste plastic etc. Things.

[0004]

According to the present invention, the base material of the gravel, in which the waste plastic and the waste tire are mixed with the concrete, is obtained by crushing the waste plastic and mixing the sand, and using an injection molding machine. Or crushed stones, pebbles, etc. are blown together with hot air into a heat-resistant container, and the crushed stones are welded by hot air while rotating, and the hot air is switched to blast to form gravel. When welded, cooled and molded, or formed by other methods and added sand to the cement, formed to the same specific gravity as the specific gravity, when casting into a concrete form, when using vibration, The fine particles of waste plastic, which are crushed and prevented from floating, are formed into a gravel shape, which increases elasticity and impact resistance, increases seismic resistance, reduces the use of gravel, and reduces the use of waste plastic when incinerated. Harmful moth It is possible to prevent the occurrence, gravel-like substrate to be mixed into the concrete still, the waste plastics to coal tar, can also be used mixed.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The base material for mixing waste plastic, waste tire, etc. into concrete according to the present invention is shown in FIG.
As shown in the enlarged sectional view, sand (1) and waste plastic fine particles (2) are mixed and formed into a gravel shape by an injection molding machine, or crushed stones and small gravel in a heat-resistant container or the like. Injecting the crushed granules of waste plastic, waste tires, etc. together with hot air, the crushed stone is rotated by the hot air, the waste plastic etc. is welded, the hot air is switched to blast and cooled, forming a gravel shape The base material (3) molded so that the specific gravity is about the same as that of a mixture of sand and cement is mixed into concrete and used for vibration when casting it into a formwork. By forming a base material that does not rise even if it rises, concrete is given elasticity and impact resistance, and it is configured to be formed on a quake-resistant, gravel-shaped base material (4). thing.

[0006]

As shown in the description based on the above embodiment, as described in the present invention, the base material made of gravel, which is used in the form of gravel, which is used by mixing with concrete, is made by mixing sand. Pulverized, waste plastic is formed into a gravel shape by an injection molding machine, or into a heat-resistant container, etc., crushed stones, small gravel, etc., and fine particles of waste plastic are blown together with hot air. The crushed stones are rotated by the hot air, the waste plastics are welded, the waste plastics are welded, formed in the form of gravel, and the hot air is switched to the blast for cooling. When formed into concrete, the specific gravity is light, to prevent the plastic from floating. In addition, a specific gravity equal to that of sand added to cement forms a base material of the same specific gravity, and concrete is poured into the formwork.At the time of construction, even if vibration is used, it does not float, so it is shock resistant, earthquake resistant There is a nature, It has the effect of reducing the generation of harmful gas when incinerating garbage such as waste plastic and waste tires, and it can be used even if the types of raw plastic are mixed, There is no need to wash the water, and the hot air blown into the heat-resistant container can be supplied from the incineration of combustible garbage incineration of combustible garbage and waste heat. it can.

Claims (1)

[Claims] 1. A mold is formed and arranged to grind waste plastic, waste rubber, tires, etc. to form a gravel in order to prevent the floating of the plastic having a low specific gravity and a small specific gravity. Injection-molding the sand-mixed material into a fine grain, and the waste plastic adheres to the melted sand to form a gravel-like shape, or crushed stone in a heating vessel with small gravel crushed stones as the core The waste plastic is blown together with hot air and the crushed stones are rotated by the hot wind, so that the waste plastic is welded and formed into a gravel form and used as a concrete substrate, or according to other methods. A gravel-like base material with elasticity and impact resistance is made by adding sand to cement to the same specific gravity as the specific gravity.The base material is placed in a concrete formwork and does not float even when using vibration. Mix wood and use gravel A concrete base material formed into a gravel-like form that reduces the use, prevents the generation of harmful gases when incinerating waste plastics, waste tires, etc., reduces garbage, generates elasticity, and increases earthquake resistance. It is also possible to reduce the amount of waste plastic waste by directly mixing the waste granules of waste plastic with coal tar or the like.
