品形状に加工される。In the granular composite material of the above (1), the bulk density is 0.
Since it is controlled to 3 g / cm 3 or less, the specific gravity is almost constant as a whole, regardless of the variety of materials used, and it can be easily used as a raw material for other materials such as soundproofing materials and U-shaped grooves. Can be done. Therefore, it has been buried and incinerated as unusable because it contains many kinds of materials in the past, but by managing it according to the bulk density standard, it can be used as a raw material for other things as if handling one kind of material. Will be available. The method for producing a granular composite material according to (2) above is a method for obtaining a granular composite material according to (1) above, in which metal is removed from shredder dust and then crushed into various sizes of about 10 to 20 mm or less. A granular composite material having a bulk density of 0.3 g / cm 3 or less is automatically obtained. In the method (3), the bulk density is 0.
By sieving a base material of 3 g / cm 3 or less with a sieve having a size larger than the size of the crusher by a predetermined amount (for example, +3 mm), and dividing it into one on the sieve and one on the sieve (passed through the sieve). , Can automatically be divided into lighter ones (urethane, fibers, etc.) and slightly heavier ones (plastic, rubber, etc.),
For example, a light material can be used as a soundproof material and a slightly heavy material can be used as a U-groove material, depending on the application. In the above (4), since the composite material is solidified with the resin material and is secondary processed (solidified), it is easy to handle,
If the shape to be solidified is the final product shape, it will be the final product as it is. In the above (5), since the resin material for hardening is fibrous, the strength of the solid body is high. When the final product is a plate-shaped soundproof material, it can be used as it is as a soundproof material when it is made into a solid body. In the above (6), since the resin material for hardening is composed of the granular composite material and the tie material (such as fluff, cotton, hemp, and synthetic fiber), the strength of the solid body becomes higher. In the above (7), since the resin material is the composite fiber, the strength of the solid body is high. In the above (8), since the automobile soundproofing material is the final product for use, when the scrapped vehicle shredder dust is used as the shredder dust, the material can be recycled from car to car. In (9) above, since the resin material is a urethane-based adhesive material, the solid body has high hardness and strength and can be used as a U-shaped groove. In the above (10), the solid material having a predetermined shape is solidified by mixing with the resin material and heating. In the above (11), it is further processed into a desired final product shape by hot pressing.

になる。The above-mentioned granular composite material 1 is manufactured by the method shown in FIG. First, in step 11, shredder dust is prepared. Next, in step 12, the shredder dust is passed through a rotary sieving machine (those having openings of 10 to 20 mm) to collect dust of a size of about 10 to 20 mm or more (those remaining on the sieve, step 13). . The small, powdery dust that has passed through the screen is discarded or regenerated for other uses. Then, in step 14, the shredder dust having a size of about 10 to 20 mm or more is subjected to a magnetic separator to remove the iron material. Then, in step 15, the shredder dust is passed through a non-ferrous metal sorter to remove non-ferrous metals such as aluminum and copper. The magnetic separator and non-ferrous metal separator described above may be conventionally known ones. Then, in step 16, the wire harness is removed. The wire harness is longer than granular plastics, rubber, urethane, fibers, etc., and can be removed by passing through a lattice comb. The wire harness removed is sorted and collected as a light granular mixture (Step 1
7). This light composite is then run at least one stage in a rotary crusher in step 18 to remove granular dust that was about 10-20 mm in size to various sizes below about 10-20 mm, for example 1, 2, 3, 6, 8, 12
Mill to mm or the like. The material obtained in this step is the base material (step 19), and the granular material of this base material does not contain a metal,
It is composed of mixed granules having various sizes of about 10 to 20 mm or less, which are mainly composed of plastic, fiber, urethane and rubber. As shown in FIG. 3, this base material has a bulk density between the upper limit and the lower limit of the base material and a particle size of 1 to 20.
In the range of mm (up to 12 mm is shown in the figure), regardless of the particle size, approximately 0.3 g / cm 3 or less (0.3 to 0.05
g / cm 3 ). Therefore, by subjecting the particle size to various sizes of 1 to 20 mm by crushing in step 18, the bulk density is automatically reduced to 0 regardless of including various materials, that is, plastic, rubber, urethane and fiber. It can be controlled to less than 0.3 g / cm 3 . This makes it easy to reuse as a raw material for other things,
It will be possible to recycle materials that have been landfilled or incinerated.

Then, the light granules (urethane, granules containing fibers as the main component, hereinafter referred to as material A) which were passed through a rotary sieving machine having a crushed particle size + about 3 mm and remained on the sieve and (in step 21) (Collection), a slightly heavy granular material under the sieve (a granular material mainly composed of plastic or rubber, hereinafter referred to as material B) and (step 22
(Collected in)). Plastic and rubber have a small particle size expansion due to expansion (spring back) of the material after crushing, and pass through a sieve with a diameter of about 3 mm larger than the crushed particle size of the crusher, but urethane and fiber are The expansion of the particle size due to expansion is large, and it cannot pass through the mesh of the sieve.
It is roughly classified into plastics and granular materials composed mainly of rubber. In the above, the crushed particles are crushed by different crushers,
By selecting each time with a crushed particle size + 3 mm sieve, the granular material is, for example, an A material having a particle size of about 12 mm, a B material having a particle size of about 12 mm, an A material having a particle size of about 8 mm, It can be classified into B material having a particle diameter of about 8 mm, ..., A material having a particle diameter of about 1 mm, and B material having a particle diameter of about 1 mm. Then, the respective bulk densities are measured and plotted, as shown in FIG. The material B exhibits a substantially uniform bulk density with various particle sizes (the bulk density hardly varies), while the material A varies between the upper limit value and the lower limit value (0.12 to 0.03). However, the variation is small, and the specific gravity of the material is about 0.06 for the A material and about 0.23 for the B material. And
This can be said regardless of changes in particle size and materials. Therefore, various materials, 1mm ~ 20m
It is shown that the base material containing various particle diameters of m can be further separated into industrial materials having a specific gravity that is almost constant and easy to handle, which makes the material recycling more appropriate and easy.
