Described acrylate rubber is auspicious father-in-law AR72HF.Described filler is StruktolWS280.Described plasticizer is ROHM AND HAAS TP-759.Described vulcanizing agent is TCY.
The preparation method of described acrylate rubber, step is as follows by weight:
(1) mixing: putting into acrylate rubber 90-110 part in mill, adjustment roll spacing is 5-6mm, at the 35-45 DEG C of 8-12min that plasticates；Filler 2-4 part, stearic acid 0.5-2 part and age resistor Naugard4452-4 part is put into after having plasticated, mix homogeneously, continue to put into white carbon black N33040-50 part and plasticizer 5-10 part, mixing uniformly, continue to put into vulcanizing agent 0.6-1 part and accelerant B Z1-2 part, roll spacing is adjusted to 1-2mm after feeding intake by 4-6min, plays four triangle bags, and roll spacing is finally adjusted to 7-8mm bottom sheet；
(2) once sulfuration: the elastomeric compound taking the bottom sheet that step (1) obtains puts into preheated mold cure, and curing temperature is 170-180 DEG C, and cure time is 450-510s, and sulfide stress is 150kg, the rubber once vulcanized；
(3) post-cure: taking in the rubber feeding baking oven that step (2) gained once vulcanizes and carry out post-cure, oven temperature is 165-175 DEG C, and cure time is 2-6h, namely obtains product acrylate rubber after sulfuration.
Beneficial effects of the present invention: present invention improves the defect of existing acrylate rubber compression set, its intensity is made to meet popular TL52293 standard, reduce the cost of this material simultaneously and improve its processing performance so that it is there is low price high technology, many-sided advantage such as high suitability.
