Abstract
The present invention discloses a centrifuge drum sealing ring, which is composed of the following raw materials: active chlorine acrylic rubber AR100 (Jinxin Chemical), butadiene-acrylonitrile rubber LG6250, modified PTFE, antiager TPPD, antiager NBC, polyethylene micropowder wax, No. 3 white oil, tribasic lead sulfate, antioxidant BHT, super wear-resistant carbon black N234, sepiolite, triallyl cyanurate, accelerator TETD, and dioctyl phthalate. The sealing ring is high in air tightness, abrasive resistance, heat resistance and aging resistance, helps to improve bonding strength of polytetrafluoroethylene by addition of modified PTFE, and enhances the stability of the sealing ring, so that the seal ring can be used for a long time in different work environments, the service life of the seal ring is extend, and the resources are saved.
Description
Technical field
The present invention relates to the rubber composite manufacture field, be specifically related to a kind of centrifuge drum wear ring.
Background technology
Along with the production of whizzer miscellaneous and widely use, the performance quality of centrifuge drum wear ring has also received great concern, and therefore producing the wear ring better, that performance is more perfect just seems of crucial importance.
Summary of the invention
The invention provides a kind of centrifuge drum wear ring.
The present invention adopts following technical scheme to achieve these goals:
The prosperous chemical industry of acrylic rubber containing active chlorine AR100(gold) 60-65, butadiene-acrylonitrile rubber LG6250 55-60, modified ptfe 4-5, anti-aging agent TPPD 1-2, antioxidant NBC 0.8-1.2, polyethylene micropowder wax 3-4, No. 3 white oils 3-4, lead sulfate tribasic 2-4, antioxidant BHT 1-2, super abrasion resistant carbon black N234 90-100, sepiolite 15-20, iso-cyanuric acid triallyl ester 1-1.5, acceterator TE TD 1-2, dioctyl ester 2-3 a kind of centrifuge drum wear ring is characterized in that it is comprised of the raw material of following weight parts:.
The preparation method of described centrifuge drum wear ring may further comprise the steps:
(1) prepares raw material according to the material component of described each weight part, each raw material is put into Banbury mixer, by the Banbury mixer synthetic rubber, and filter;
(2) synthetic rubber after detection is filtered is opened the type of being smelt with detecting qualified synthetic rubber by mill, the rubber after the moulding is put into the mould of vulcanizing equipment, at pressurization 180～185Kgf/cm again
2, be warming up under 165～175 ℃ the condition, add weight part and be 0.8-1 vulcanizing agent PDM, rubber is carried out sulfidizing, the time length is 360～480 seconds;
(3) rubber of step (2) sulfidizing being crossed carries out deburring, check, packing, warehouse-in.
The preparation method of described modified ptfe is: be tetrafluoroethylene, graphite, glass fibre, the linking agent TAC of 80:3-4:2-3:2-3 with mass ratio, 150-200 mesh sieves are crossed in mixed grinding, oven dry.
Advantage of the present invention:
Wear ring resistance to air loss of the present invention, wear resistance, thermotolerance, resistance to deterioration are all very strong, improved the cohesive strength of tetrafluoroethylene by adding modified ptfe, strengthened the stability of wear ring, so that the sealing ring can use under different Working environments for a long time, prolong the work-ing life of wear ring, saved resource.
