METHOD OF PRODUCING ABSORBING MATERIAL Russian patent published in 2017 - IPC C09D5/32 C08L83/04 C08K3/18 C08K5/54 

FIELD: chemistry.

SUBSTANCE: as a component of the absorbing material, a composition containing synthetic low molecular weight dimethylsiloxane SKTN, ethyl silicate-40, iron carbonyl radio grade P-10, cold curing catalyst 68, the composition is selected as an absorbent material, the composition is used in the following ratio, pts wt: synthetic low molecular weight synthetic dimethylsiloxane SKTN 15-25; ethylsilicate 401.5-2.5; iron carbonyl radio engineering grade R-10 105-175; cold curing catalyst 68 0.375-0.625. The method includes the steps of premixing, in a container manually in accordance with the formulation, SKTN rubber, ethyl silicate-40, iron of the carbonyl radio grade P-10, then mixing at a stirrer at 300 rpm for 2 minutes, after which dispersing the mixture by ultrasonic action with submerged radiator for 20 minutes at a frequency of 22 kHz, cooling the resulting mixture to room temperature, adding K-68 catalyst, stirring at a stirrer at 300 rpm for 2 minutes, pouring into a mould and curingat a temperature of (25±10)°C for not less than 20 hours, then at a temperature of (160±5)°C for 7 hours.

EFFECT: producing a material with reduced shrinkage, increased absorption of signal wave, reduced signal wave attenuation and stability after various climatic and mechanical effects.
