Abstract
The invention discloses a method for manufacturing regenerated rubber. The method comprises the following steps: desulphurizing rubber powder, refining the rubber powder, drying and cooling the rubber powder after desulphurization to decrease the temperature of the rubber powder to be below 50 DEG C, and refining the rubber powder again. According to the invention, a drying and cooling procedure is added between the conventional desulphurization and refining procedures, that is, after being desulphurized, the rubber powder enters a drier immediately to be dried and cooled, and then is refined. After the drying and cooling procedure is added, the rubber powder can stop desulfurization reaction immediately after being dried and cooled by the drier, so that the main chain of rubber is protected from being damaged, and the strength of regenerated rubber can be ensured; and meanwhile, after the rubber powder is dried, water in the rubber powder is adsorbed, so that the refining can be carried out conveniently.
Description
Technical field
The invention belongs to the Rubber processing manufacture technology field, relate in particular to a kind of method of processing and fabricating regenerated rubber.
Background technology
At present, in regenerated rubber fabrication and processing field, usually waste rubber goods for example junked tire be processed into rubber powder; Again rubber powder is carried out desulfurization and handle, directly carry out refining treatment to the rubber powder after the desulfurization then, the shortcoming of this method is to be piled into a pile through the rubber powder that desulfurization is handled can not in time dispel the heat; The middle part still has higher temperature, and rubber powder is still carrying out desulphurization reaction, and rubber backbone is damaged; The intensity that can't keep shoddy causes the shoddy quality to descend.
Summary of the invention
For solving the problems of the technologies described above, the present invention provides a kind of method of making regenerated rubber, comprises the step with the rubber powder desulfurization; With said rubber powder purified step; Said rubber powder carries out the drying cooling behind desulfurized step, said rubber powder temperature is reduced to below 50 ℃, gets into refinement step again.
The present invention is through increasing dry together refrigerating work procedure between existing desulfurization and refining procedure, promptly rubber powder gets into the moisture eliminator drying immediately and cools after desulfurization is accomplished, and then the entering refining procedure.Rubber powder cools through moisture eliminator after increasing dry refrigerating work procedure, can stop desulphurization reaction immediately, and the protection rubber backbone is not damaged, and has kept the intensity of shoddy; After drying, the moisture in the rubber powder is adsorbed, and is convenient to refining simultaneously.
Embodiment
Below in conjunction with specific embodiment the present invention is made and to further specify.
Blob of viscose by junked tire is cut into is sent into crusher through transfer roller; Be broken into rubber powder; Rubber powder is fallen the enterprising row filter of vibratory screening apparatus again, and the rubber powder that sieves is sent into the magnetic separator magnetic separation by transfer roller, is absorbed by the broken steel wire that the strong magnetic roller on the magnetic separator will mix in rubber powder.
Rubber powder, acvator and the tenderizer that will pass through magnetic separation drop in the digester, carry out the HTHP desulfurization process; After desulfurization is accomplished; Immediately rubber powder is sent into moisture eliminator through worm conveyor and carry out drying and cool, treat that the temperature of rubber powder is reduced to below 50 ℃, also can prolong dry cooling time; Make the temperature of rubber powder reduce to room temperature; Can stop the desulphurization reaction of rubber powder so fully, the protection rubber backbone is not damaged, and again rubber powder is sent into refining procedure.
Because desulfurization rubber powder water ratio after the moisture eliminator drying reduces, and in refining procedure, only can reach the refining effect of original four refiners with three refiners, the employing novel method compare with aging method artificial the contrast of energy consumption see table 1.
The new old technology of table 1 is artificial, the energy consumption contrast
The description of above embodiment is comparatively concrete, detailed; But can not therefore be interpreted as restriction to scope; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the present invention's design; Can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (2)
1. method of making regenerated rubber; Comprise the step with the rubber powder desulfurization, with said rubber powder purified step, it is characterized in that: said rubber powder carries out the drying cooling behind desulfurized step; Said rubber powder temperature is reduced to below 50 ℃, get into refinement step again.
2. according to the method for the said making regenerated rubber of claim 1, it is characterized in that: temperature was reduced to room temperature when said rubber powder carried out the drying cooling.
