Abstract
The invention provides a formula for migration-free odorless natural reclaimed rubber, which belongs to the field of rubber. The manufacturing method comprises the following steps: on the basis of 100 parts of natural rubber powder, weighing and mixing the natural rubber powder, an activator 480, YNT800, naphthalene and sodium bicarbonate; adding the mixed substances into a desulphurization tank, heating the desulphurization tank to 200 DEG C, maintaining the temperature for about 120 min, releasing gas every half an hour, and maintaining a pressure of 2.5 MPa for 30 min under the condition of a temperature of 200 DEG C; after completion of desulphurization, carrying out batching off; and then carrying out performance detection. The invention has the following advantages: naphthalene exerts activation effect in the preparation of the reclaimed rubber, can improve the physical properties of the reclaimed rubber and enables the phenomenon of migration not to occur; sodium bicarbonate is used for neutralizing acidic gas produced in the process of desulphurization; and with the formula containing naphthalene and YNT800, all the performance indexes of the reclaimed rubber meet standard requirements, and the reclaimed rubber is free of migration on its surface and free of odor.
