COMPOSITION OF SHOCK-ABSORBING MATERIAL Russian patent published in 2014 - IPC C08L83/04 C08K3/22 C08K3/38 C08K13/02 

FIELD: chemistry.

SUBSTANCE: invention relates to field of chemistry, in particular to compositions, based on polyorganosiloxane for application as shock-absorbing material, absorbing shock mechanical energy in vehicles, mechanisms, apparatuses, operating on earth, in air and space. Composition of shock - absorbing material contains polydimethyldiphenylsiloxane caoutchouc of general formula HO[(Me₂SiO)_n(Ph₂SiO)_m]_kH, where n, m represent molar content of links, n+m=100 when m=4÷12, k=33÷69, boric acid or its ether, iron oxide, titanium dioxide as semi-reinforcing filling agent, wollastonite as reinforcing filling agent, magnesium oxide as thickening agent, and talc and fluoroplast as antiadhesive components.

EFFECT: elaboration of composition of shock-absorbing material, which ensures penetration of 160-220 convunits and absence of crystallisation at temperature minus 80°C for two hours.
