Abstract

In the work the multicomponent epoxy-polyester coating with improved cohesive properties was developed by the method of mathematical planning of the experiment. The optimum content of the two-component filler was found: activated carbon (d = 5...10 µm) – 5...10 pts.wt., carbon fiber (d = 6...8 µm, l = 0.5...1.5 mm) – 0.1 pts.wt. per 100 pts.wt. of epoxy-polyester matrix. Introduction the two-component filler to the epoxy binder allows to increase the indexes of the elasticity modulus during the flexion of the protective coatings to E = 4.7...5.0 GPa. The influence of two-component filler on the impact strength of developed epoxy-polyester composite was proved. It was found that the optimal content of two-component filler: activated carbon – 5 pts.wt., carbon fiber – 0.1 pts.wt. per 100 pts.wt. of epoxy-polyester binder. Introduction the two-component filler to epoxy-polyester binder allows to increase of the impact strength up to W = 8.8 kJ/m2. The obtained results allow to create a polymeric coating with improved complex properties of cohesive properties.
