METHOD FOR FUSING GASKET MANUFACTURE Russian patent published in 2018 - IPC C09J5/06 C08J5/12 C09J163/00 

FIELD: chemistry.

SUBSTANCE: method for fusing gasket manufacture, comprising the following sequence of actions: I. The following is successively charged in the reactor with the agitator turned on (parts by weight): - solvent - toluene - 50; - solvent - acetone - 50; - solvent - trimethylethylsilane 0.2-0.6; - epoxy diane resin - 100; - spherical particles of butadiene-nitrile-styrene-carboxylate polymer - 5-20; - fusing gasket components, determined by the composition for its operation conditions. II. Stirring until the epoxy resin is completely dissolved at a temperature of 20-30°C. III. Impregnation of fiberglass (130 parts by weight) with the resulting solution. IV. Drying of the solution-impregnated fiberglass in the shaft of a vertical impregnating machine at a temperature of 240-243°C for 4-4.5 minutes.

EFFECT: ensured stable low warpage of the fusing gasket.
