EPOXY BINDER FOR HIGH-STRENGTH GLASS-BASALT PLASTICS Russian patent published in 2025 - IPC C08L63/00 C08L9/02 C08K5/09

Abstract RU 2839024 C1

FIELD: chemistry.

SUBSTANCE: invention relates to epoxy composite materials. Disclosed is an epoxy binder for glass basalt plastics, which is a material of a high-pressure radiotransparent housing for devices for electromagnetic well logging when searching for oil and gas, consisting of epichlordian resin (ECR) components, curing agent isomethyltetrahydrophthalic anhydride (Iso-MTHPA) and plasticizer of butadiene-nitrile rubber (SKN-26-1A), wherein weight ratio of components is defined as: ECR = SKN-26-1A+Iso-MTHPA.

EFFECT: reduction of internal stresses during polymerisation of composite material due to exhaustion of reactive groups, which ensures achievement of high strength properties and stability of dielectric characteristics.
