Further, described turning axle shape rubber seal is made by the raw material of following weight part: 100 parts of butadiene-acrylonitrile rubbers; 10 parts in zinc oxide; 5 parts of stearic acid; 3 parts of antioxidant 4010s; 5 parts in paraffin; 50 parts of carbon black N660; 4 parts of dibutylesters; 0.5 part in sulphur; 1.2 parts of TM monex TD.
A kind of production technique of turning axle shape rubber seal may further comprise the steps:
1) 95～100 parts butyronitrile rubber is dropped into plasticate in the Banbury mixer after, park 24 hours stand-by;
2) will mould the butyronitrile rubber perfected and drop into Banbury mixer, add 8～10 parts in zinc oxide, 3～5 parts of stearic acid, 45～50 parts of carbon black N660,3～5 parts in paraffin, 2～4 parts of dibutylesters, 1～3 part of antioxidant 4010 respectively, after the banburying, park 24 hours stand-by;
3) sizing material that banburying is good is put into opening rubber mixing machine and is opened refining, adds 1～1.2 part of TM monex TD, 0.3～0.5 part in sulphur, and check is opened and entered filter after the refining and filter, park 24 hours stand-by;
4) with qualified sizing material, open refining with opening rubber mixing machine after, enter forcing machine and be extruded into adhesive tape, neatly be placed on the pallet stand-byly then, extrusion temperature is controlled at 65～80 ℃;
5) Steel Skeleton is cleaned with 30% hydrochloric acid earlier, clean up with clear water, and then dry, in case influence bondingly, the gluing airing is stand-by;
6) Steel Skeleton and sizing material are bonding by mold pressing, and the adhesive tape of extruding is gone into the mould sulfuration at vulcanizer;
7) after the sealing-ring cooling that vulcanizates, put into and use lathe, carry out the deburring arrangement with mill yarn rod;
8) put in storage after the assay was approved.
Further, described step 6) curing temperature control is 150～180, and the time was controlled at 5～10 minutes, and pressure-controlling is at 8～12MPa.
Compared with prior art, beneficial effect of the present invention is:
1, by improving the raw materials for production of traditional rubber seal products, adopt reasonable raw material prescription and advanced Technology, solved the oil resistant of sealing article to a great extent, anti-liquid and old chemical difference performance are low, the performance deficiency of aspects such as production efficiency is low, improved quality product service requirements, further improved the stability of product.
2, these turning axle shape rubber seal products performance index are higher than other like products far away, make tensile strength improve 2MPa, and elongation has also improved 70%-150%, and every technical indicators such as the anti-liquid of oil resistant had surpassed national standard.
3, technology of the present invention is reasonable, and various starting material close evenly, and product is mixing evenly, prepared turning axle shape rubber seal tool will have advantages such as ageing-resistant, anti-liquid, tensile strength and elongation, thereby has reduced wearing and tearing, phenomenons such as leakage of oil, constant product quality, longer service life.
