Two Roll Mills For Elastomers

  • Mill Behavior of Rubber on Two Roll Mill with Temperature

    In region 2 a good elastic rubber band is obtained on one of rolls. In region 3 the elastomer crumbles and bagging or crumbs occur. In region 4 a melt fluid coats on one of rolls at high roll temperature. In this paper, mill behavior of rubber on two roll mills with the variation of temperature was expressed.

    This paper presents two kinds of magnetorheological elastomers (MREs). One is composed of appropriate silicon rubber, carbonyl iron particles and some other materials. It is cured under a strong magnetic field at a room temperature. Its shear modulus change from 0.34MPa at zero magnetic field to 3.34MPa at 1T magnetic field, the relative MR effect reaches 878%.

    2.2. Methods. Elastomer mixtures, based on ethylene-octene copolymer filled with carbonyl iron powder, carbon black, and cross-linking agent (dicumyl peroxide), were prepared using a laboratory two–roll mill, with roll dimensions of D = 140 mm and L = 300 mm. The rotational speed of the front roll was = 16 min −1; the friction and the width of the gap between rollers were 1-1.2, 1.5-3 mm.
