HEAT-SHIELDING MATERIAL Russian patent published in 2024 - IPC C08L9/00 C08L23/16 C08K13/06 C08K7/10

Abstract RU 2829741 C1

FIELD: chemistry.

SUBSTANCE: invention relates to heat-shielding materials and can be used in aircraft and rocketry. Heat-shielding material based on ethylene-propylene diene rubber “СКЭПТ-40” contains curing agents – sulphur, thiuram “Д”, dithiodimorpholine, vulcanisation accelerator – 2-mercaptobenzothiazole, vulcanisation activators – zinc oxide and stearin, technical carbon “П-325”, white soot “БС-120”, pine rosin and a modifying additive preliminarily deposited by way of thermostatting on ceramic microfibres. Modifying additive used is a product of reaction of nitrilotrimethylphosphonic acid, diethylene glycol and boric acid, which is pre-neutralized to pH=7-7.3.

EFFECT: improved heat-shielding properties of the material.
