DEVELOPMENT OF THE COMPOSITION OF A COMPOSITE MATERIAL BASED ON THERMOREACTIVE BINDER ED-20

The aim of the study is to determine the effect of the type of structural modifier and filler on the structure formation and technological properties of potting composite polymeric materials (HCPM) and protective coatings for sheet and complex-configuration technological equipment, taking into account their rheological properties. Compositions of composite polymer materials based on a thermosetting binder of epoxy-diane resin ED-20 filled with a mineral filler - kaolin modified with gassipol resin (GS) - were developed using Newton\u27s interpolation formula and the Lagrange method. The optimal amount of gossypol resin determined in the composition of the composite – in the amount of 6-10 mass., including in relation to sheet coverings and 8-12 wt. h. for parts of large-size complex-configuration technological equipment
