Abstract
The steps of the method are as follows: the fixed quantity of decomposition agent and auxiliary decomposition agent are taken in accordance with specific proportion, then mixed and dissolved, then the mixed solution is put in the container of fixed quantity of waste rubber powder, then it is finished through mixing uniformly, heating, pugging mullering, repeatedly refining and becoming into level thin sheet of regenerated rubber. Said invention features simple process and no waste produced in the course of production.
Description
The invention belongs to the regeneration technology of waste vulcanized rubber, is a kind of method that adopts the distintegrant legal system to be equipped with reclaimed rubber.
For making full use of regenerated resources and protection environment; people more and more pay attention to the regeneration and the comprehensive utilization of waste vulcanized rubber; the manufacture method of reclaimed rubber has multiple at present; usually all be under the heating pressurized conditions; waste vulcanized rubber is carried out machinery or chemical treatment; make the degraded of vulcanized rubber cross-linked network and give plasticity; vulcanize the reclaimed rubber of processing again and become; all there is the production cost height in these methods; energy consumption is big; complex process; and produce a large amount of waste water again simultaneously; waste gas and nuisance, serious environment pollution, especially the damaged tire tread-rubber is by natural rubber; butadiene-styrene rubber and butadiene rubber add the mixing sulfuration of various auxiliary agents and make; its regeneration is general oil process; water/oil method; this technology can be regenerated waste vulcanized rubber, but its resolution ratio only reaches 30%, have greatly limited the range of application of this kind reclaimed rubber.
The objective of the invention is to, overcome the deficiency that prior art exists, propose the method for preparing regenerated rubber by decomposition method that a kind of no waste produces.
Following mode can realize the present invention:
Get waste Crumb rubber (3-5) part by weight, distintegrant (0.3-0.7) part, help distintegrant (0.01-0.04) part, waste Crumb rubber places container, distintegrant with help distintegrant to mix, stir, make and help distintegrant to be dissolved in the distintegrant fully, again with distintegrant and help the distintegrant mixed solution in stirring, slowly to add in the waste Crumb rubber container, it is fully mixed, in (100-120) ℃ temperature kneading 50-60 minute then, leave standstill 3-4 hour again after, take out and be placed on the conche, smooth thin slice reclaimed rubber is made in refining repeatedly.
Distintegrant is the monocyclic monoterpene ene compound that contains two two keys, as compounds such as polyprene, limonenes.
Helping distintegrant is naphthenate, as cobalt naphthenate, manganese naphthenate etc.
The waste Crumb rubber granularity is below 30 orders.
Preparation technology of the present invention is simple, through distintegrant and the product that helps after distintegrant regeneration is handled, need not remove distintegrant and help distintegrant, needn't cool off, can carry out kneading, refining, cost is low, do not produce discarded object in process of production, non-environmental-pollution is after adjusting in recipe ingredient and process conditions scope, can prepare the reclaimed rubber of different decomposition rate, satisfy different purposes needs.
Embodiment 1
Get waste Crumb rubber 300 grams of granularity below 30 orders, put into stainless steel, aluminium alloy or enamel ware, help distintegrant cobalt naphthenate 1 gram, concentration is 60%, joins in distintegrant polyprene 30 grams, after mixing is stirred to and helps distintegrant and distintegrant to dissolve fully, slowly join in the waste Crumb rubber container while stirring, under 100 ℃ of temperature, kneading 60 minutes, leave standstill 3 hours after, taking-up is refining repeatedly on conche, make smooth thin slice, coiling and molding promptly is the finished product reclaimed rubber.
Embodiment 2
Get waste Crumb rubber 500 grams of granularity below 30 orders, put into stainless steel ware, get and help distintegrant manganese naphthenate 4 grams, join in Fen Xie Ji limonene 70 gram, mix, be stirred to help distintegrant and distintegrant to dissolve fully after, in stirring, slowly join this solution in the waste Crumb rubber container, after mixing, under 120 ℃ of temperature, kneading 50 minutes, leave standstill 4 hours after, taking-up is refining repeatedly on conche, make smooth thin slice, coiling and molding promptly is the finished product reclaimed rubber.
In recipe ingredient and process conditions scope, adjust prescription and corresponding technological conditions, can produce the reclaimed rubber of different decomposition rate.
Claims (4)
1, a kind of method for preparing regenerated rubber by decomposition method, get waste Crumb rubber (3-5) part by weight, distintegrant (0.3-0.7) part, help distintegrant (0.01-0.04) part, waste Crumb rubber places container, distintegrant with help distintegrant to mix, stir, make and help distintegrant to be dissolved in the distintegrant fully, with distintegrant and help the distintegrant mixed solution in stirring, slowly to add in the waste Crumb rubber container, it is fully mixed again, in (100-120) ℃ temperature kneading 50-60 minute then, after leaving standstill 3-4 hour again, taking-up is placed on the conche, and smooth thin slice reclaimed rubber is made in refining repeatedly.
2, preparation reclaimed rubber method according to claim 1, it is characterized in that: the waste Crumb rubber granularity is below 30 orders.
