| description |
It is proved, that for improving the performance characteristics of vehicle parts, including their corrosion resistance and wear resistance, it is advisable to use protective polymeric composite coatings. It is shown that in order to increase the indexes of physical-mechanical and thermophysical properties in the epoxy binder, it is necessary to introduce additives: modifiers, plasticizers, dispersed and fiber fillers. The introduction of dispersed additives into the epoxy binder is actual. It this case, it is effective to use fillers of different dispersity in the complex. The influence of two-component polydispersed filler on the elasticity modulus in flexure of the developed epoxy composite is analyzed. The critical content of a two-component polydispersed filler is found by the method of mathematical planning of an experiment. a mixture of nanodispersed compounds 1 (d = 20 . . . 80 nm) − 0.75 . . . 1.0 pts.wt., a mixture of discrete fibers 1 (l = 0.5 . . . 1.0 mm, d = 18 . . . 25 µm) – 0.2 pts.wt. by the 100 pts.wt. of the epoxy oligomer ED-20. An introduction of the two-component polydispersed filler to the epoxy binder allows significantly to increase the values of the elasticity modulus in flexure of the protective coatings to = 4.8 . . . 5.0hP a. Additionally, the effect of two-component polydispersed filler on the impact resilience of the developed epoxy composite was determined. It is proved that the critical content of a two-component polydisperse filler is: a mixture of nanodispersed compounds 2 (d = 30 . . . 40 nm) − 1.00 . . . 1.25 pts.wt., a mixture of discrete fibers 2 (l = 0.5 . . . 1.0 mm, d = 18 . . . 25 µm) − 0.1 . . . 0.2 pts.wt. by the 100 pts.wt. of epoxy ED-20. An introduction of the two-component polydispersed filler to the epoxy binder allows significantly to increase the values of the impact resilience to W’ = 10.0. . . 10.2 kJ/m2. The obtained results allow us to create polymeric coating with improved indexes of the physical and mechanical properties in complex.
