Abstract

SUMMARY

APPLICATION OF THE DESIGN OF EXPERIMENTS IN THE PREPARATION OF RUBBER BLENDS BASED ON NBR, CR AND PVC

The preparation of rubber blends which aims at having higher properties and reasonable cost, based on nitrile butadiene rubber (NBR), choloroprene rubber (CR) and PVC.

By using the design of experiments, a mathematical model describing the relationship between the tensile strength y and compositions NBR (x₁), PVC (x₂), CR (x₃) has been found. It has a form as follow:

y = 14.2664x₁ – 5.7154x₂+ 13.028x₃ + 2.0824x₁x₂

+ 25.1865x₁x₃ + 0.925x₂x₃ + 262.3118x₁x₂x₃

in the range of the variables: 0.2 ≤ x₁≤ 0.6; 0.1 ≤ x₂≤ 0.4, 0.2 ≤ x₃≤ 0.5, and x₁+ x₂+ x₃ = 1.

The optimal conditions have been determined by the algorithm FLEXIPLEX of nonlinear programming
