Description

The invention relates to the field of electrical engineering and may find application in particular as an electrical insulating compound. Electroinsulating com pounds based on epoxy and polyester resins l, 22 are known. One of the major drawbacks of these compounds is their insufficient thermal conductivity. The purpose of the invention is to create a computer that has a thermal conductivity coefficient of your 1.4 W / m heating. The goal is achieved by the fact that the electrically insulating compound, including an unsaturated resin, a curing initiator, a filler, contains an oligoether acrylate as an unsaturated resin, a coarse quartz sand matrix, a mixture of coarse quartz sands, and a mixture of coarse quartz sands, a mixture of coarse quartz sands, a mixture of coarse quartz sand, a mixture of coarse quartz sand, and a mixture of coarse quartz sands, a mixture of coarse quartz material, and Young finely divided particles with a particle size of 0.1-0.3 mm with the following ratio of components.% Oligoether acrylate 17-20 Isopropylbenzene hydroperoxide 1.1-1.2 Organic cobalt salt2.3-2.5 Coarseness quartz sand with particle size 0.8-2 mm 34.1-35.4 Fine-grained quartz sand with particle size 0.10, 3 mm42.2-44.2 A p. Coarse quartz sand with a particle size of 0.8-2 mm in the amount of 95.9 g (34.1 wt.%) Is poured into the filled form to the top, shaken on a shaker table, then fine silica sand is poured with a particle size of 0.1- 0.3 mm in the amount of 115.3 g (42.2 wt.%) And shredded until shallow fine sand penetrates completely between the large particles of sand. Next, pour a mixture of oligbasification with TGM-3 51.9 g (20 wt.%), Isopropyl benzene hydroperoxide - 3.3 g (1.2 wt.%) And organic cobalt salt - 6.83 g (2.5 wt.%) . The resulting compound is dried at 70-75 C for 3-3.5 hours
