Problems solved by technology
[0006] However, when the raw material is unconditionally cut and pulverized as in the above-mentioned conventional method, there is a problem that the quality of the rubber solution is deteriorated due to the destruction of the molecular structure of the rubber constituting the raw material.
In addition, in the method of crushing the raw material and dissolving the crushed rubber with different devices, various operations such as storage and movement of the crushed raw material and feeding the raw material to the stirring device are required, so there is a high productivity. insufficient such problems

Embodiment Construction
[0034] Preferred embodiments of the present invention will be described below with reference to the drawings.
[0035] Manufacturing method of rubber solution
[0036] Such as figure 1 As shown, in the rubber solution production method of this embodiment, the raw material 6 is separated into lumps 61 by a method of mixing the solvent 7 with the raw material 6 and stirring while applying a shearing force to the raw material 6 . After the solid is dissolved in the solvent 7 to form a rubber solution, the solvent input process, the raw material input process, the separation process, the dissolution process, and the preparation process can be continuously performed in one container 2 . In addition, "mixing solvent 7 to raw material 6" does not limit the order of raw material 6 and solvent, both raw material 6 and solvent can be put in at the same time, and either one (raw material 6 or raw material 6) can be put in before the other (solvent 7 or raw material 6). or solvent 7)....

In order to both produce a high quality rubber solution that preserves the molecular structure of the rubber and improve productivity, the rubber solution is created by mixing a solvent (7) into a source material (6), stirring while applying a shear force to the source material (6), and separating the source material (6) into block (61) units that are subsequently dissolved in the solvent (7), thereby continuously performing a solvent addition process, a source material addition process, a separation process, a dissolving process, and a mixing process in a single container (2).
Description
technical field [0001] The present invention relates to a rubber solution production method and a rubber solution production device for dissolving rubber in a solvent to obtain a rubber solution Background technique [0002] Generally, in the case of producing a rubber solution from a large rubber mass, a production method is adopted in which, after the raw material is fragmented, the rubber is dissolved by mixing and stirring the fragmented rubber flakes with a solvent. in the solvent. For the fragmentation of raw materials in this manufacturing method, it is possible to use a guillotine-type cutting device that cuts raw materials into plates by raising and lowering the cutter, or to use a horizontally arranged cutter with a gap between the cutter and the mounting table. In addition to using a cutting device or the like that performs a slicing process by moving the raw material forward and backward on a mounting table, it can be implemented using the devices described in P...
