Chemical cross-linking such as peroxide or radiation cross-linking (by radiation) allows molecules to bond with each other, and changes the properties of the molecules to strengthen heat resistance and hardness that do not soften or melt even when heated. Possess properties. In this way, various proposals have been made for the recycling of scraps that are no longer needed for cross-linked plastic products made of covalently bonded polymers with a neat network structure. There is IRE A, which is difficult to process because it does not easily gel, and in the case of compounds containing a crosslinking agent, uncrosslinked residual crosslinking agent often remains, and there is a limit to reuse.

つでいる。Therefore, most of it is disposed of as industrial waste by incineration, but it also poses a pollution problem as it generates harmful gases during incineration and damages incinerators due to the vortex generated by combustion.

ちる。This invention solves the above-mentioned problems and is a method for regenerating plastic scrangs that are no longer needed.Resource saving and pollution11)
The purpose of this project was to solve this problem from the standpoint of preventing j, and as mentioned above, cross-linked plastics are made of covalent bonds with a network (q!) and have a q!f property that makes them less likely to gel compared to conventional plastics. I thought of the things I had and used them for exclusive use) (I was captivated by the studies and tests that led to this invention.

レット化する再生法に1泊るものである。The gist of the present invention is to crush plastic scraps without cross-linking. It is used for one night in a recycling method in which it is mixed with old plastic nuts and pelletized at an extrusion temperature of 180° to 200°C.

することが可能となるもので4)る。In the case of this 1tJ, as mentioned above, pelletization is reduced by 4% by mixing with the same value plastic that does not have a 4rili ratio.
This pellet is extremely effective as a cleaning material for cylinders in injection molding machines or extrusion machines where gelation is required in a gel state of J shielding degree. It can also be used as other molding materials (4).

浪費を生ずるという幻甲とコストの白で媚点があった。In other words, as mentioned above, in the case of cylindrical, cedar, or extruded molds, it is often necessary to change the color of the resin and the composition of the resin. It is used as a cleaning material with the same value as that of 1, but it is expensive and does not gel easily, so the cleaning effect is reduced and the cleaning effect is reduced. There was a point.

Due to its gelatinized state, it has an excellent adhesive wiping effect on molding residue in the molding pot, and compared to conventional iC, it was able to achieve a cleaning effect of 5-5 with Shoshya's resin and a shorter working time. In addition, since the discarded rack (made from crushed granules of plastic scraps7)6 is used, it is expected that a large reduction in cost will be achieved.
