Abstract
The invention concretely relates to the restoration technique of an old steel core belt used for a transmission tool. The process is completed by the following steps: 1) cleaning before the restoration: an upper old cover coat and a lower old cover coat of the steel core belt are firstly peeled off; 2) buffing: the cover coat of original belt after being peeled is buffed to increase the surface roughness; 3) cleaning: an adhesive surface is cleaned by a cleaning agent and air dried; 4) preparing glue: sulfur (S), accelerator D, accelerator TMTM, ZnO, MgO, stearic acid, polyethylene wax, moderate supersonic carbon black 220, conductive carbon black (HG-IB), white carbon black (175 model), aluminium hydroxide, ammonium polyphosphate, pentaerythritol, decabromodiphenyl oxide, MB202, triarylphoshate, ultra fine antimony trioxide are added into neoprene adhesive (PM-40) according to proportions and are stirred uniformly; 5) coating: two adhesive interfaces of an original belt and a new belt are coated three times after completing the glue preparation; 6) bonding: the original belt and the new belt are bonded ; 7) press curing.
Description
Technical field
The invention belongs to the recovery technique field of material means of transportation in the industrial production, be specifically related to a kind of renovation technique technology of old steel core band.
Background technology
In the industrial production, conveyer belt not only will bear wearing and tearing, burn into scuffing of institute's transported material etc. in running, also bear certain shear stress, under this working condition, easily cause conveyer belt concentrated wear, breakage to occur, seriously then cause situations such as longitudinal tear.
Goal of the invention:
The present invention is intended to the abrasion condition at steel wire inner core conveyer belt, and a kind of reliable and stable renovation technique is provided.
Summary of the invention
The present invention is achieved through the following technical solutions:
1) repair before cleaning: earlier the old rubber cover up and down of steel core band is peeled off, peel off stepmother's tape thickness tolerance to be controlled at ± the 0.5mm scope in.
2) polishing: the original tape rubber cover polishing after will peeling off increases surface roughness.
3) cleaning: clean bonding plane with cleaning agent, and make it dry.
4) join glue: in neoprene (PM-40), add in proportion sulphur (S), diphenylguanidine, TM monex TM, ZnO, MgO, stearic acid, Tissuemat E, in super carbon black 220, conductive carbon black (HG-IB) white carbon black (175#) aluminium hydroxide, APP, pentaerythrite, deca-BDE, MB202, triaryl phosphate, superfine antimony trioxide and stir.Required each component ratio is: neoprene (PM-40) 52.6-53%, sulphur (S) 0.43-0.45%, diphenylguanidine 0.52-0.54%, TM monex TM 0.46-0.5%, ZnO 2.1-2.3%, MgO 4.3-4.5%, stearic acid 0.89-0.9%, Tissuemat E 2.1-2.3%, in super carbon black 220 3.5-3.54%, conductive carbon black (HG-IB) 3.06-3.1%, white carbon black (175#) 7.44-7.5%, aluminium hydroxide 3.94-3.98%, APP 1.3-1.34%, pentaerythrite (carefully) 3.92-4.0%, deca-BDE 4.3-4.5%, MB2021.72-2.0%, triaryl phosphate 4.3-4.5%, superfine antimony trioxide 2.1-2.3%
5) gluing: join glue finish after in 1 hour to master tape with newly be with two bonding planes gluing three times respectively.Pressure a little during brushing ground floor glue, brushing second layer glue when treating the glued membrane solvent evaporates to leather hard, the gluing temperature is 40～50 ℃.
6) bonding: superimposed two bonding planes make it to combine closely.
7) press cure: the semi-finished product after bonding are put as vulcanizer hot plate center.The control vapour pressure is 0.32Mpa-0.35Mpa, sulfide stress 3Mpa-5Mpa.The sulfuration width should be greater than the semi-finished product width 10mm-12mm after bonding.Sulfidation finishes to close admission valve in preceding 5 minutes and opens exhaust valve, and the adhesive tape after treating will vulcanize after steam is all discharged in the hot plate is pulled out hot plate.
