Abstract

Modified germanite used for radiation-resistant high-pressure rubber hoses and a preparing method of the modified germanite are disclosed. The modified germanite is prepared from following raw materials by weight: 72-86 parts of germanite, 24-32 parts of precipitated barium sulphate, 10-15 parts of carboxyl-terminated butadiene-acrylonitrile, 14-22 parts of 4,4'-methylenedianiline epoxy resin, 2-3 parts of alkylphenol sulfide, 1.5-2.5 parts of diaminodiphenyl sulfone, 3-5 parts of ethylamine-borontrifluoride, 5-10 parts of bone glue powder, 10-15 parts of oil shale ash, 2-4 parts of trimethylolpropane triacrylate, 5-10 parts of nanometer calcium titanate fiber, 1-2 parts of dithiothreitol, 66-78 parts of polyetherimide, 2-3 part of lauroyl peroxide, 1.5-2.5 parts of 4-tert-butylthiophenol, 32-44 parts of polycarbonate, 3-5 parts of pentaerythritol oleate, 2-3 parts of 2-phenylbenzimidazole-5-sulfonic acid and 4-8 parts of auxiliary agents. The modified germanite can be well dispersed in rubber materials, and is in good compatibility with rubber. A rubber product comprising the modified germanite has excellent mechanical properties, has characteristics of radiation resistance, high-temperature resistance and high-pressure resistance, and has wide application value and a wide market prospect.

Description

technical field [0001] The invention relates to a modified germanium stone for radiation-resistant high-pressure rubber hose and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] Germanium stone is a general term for a class of ores containing germanium in nature. In recent years, germanium stone has been widely used in environmental protection, health care, electronics, medicine, chemical industry, light industry, building materials and other fields due to its characteristics of emitting far infrared rays, suppressing radiation, and preventing electromagnetic radiation. With the gradual research on the value-added application of germanium stone, its application as a mineral filler in the polymer material industry such as plastics and rubber and the field of composite materials has attracted more and more attention. However, germanite has strong polarity and fine particles, and is not easy to disperse in non-p...
