COMPOSITION MATERIAL Russian patent published in 2005 - IPC

FIELD: compositions materials.

SUBSTANCE: composition materials are prepared from composition based on hybrid binding of hot hardening - epoxy vinyl ester resin in the amount 100 mas. p. p. with peroxide hardening initiating agent, modifying agent and reinforcing filling agent. Modifying agent comprises at least one epoxy resin in the amount 70-110 mas. p. p. with anhydride hardening agent in their ratio in the mixture from 100:75 to 100:100, and imidazole hardening catalyst in the amount 0.4-0.9 mas. p. Invention provides improving technological indices, for example, to enhance working ability and wetting capacity of binding agent, to reduce its viscosity, to increase broach rate and to improve mechanical indices of composition material in storage and some increase of level of its physical-chemical properties, in particular, heat stability, chemical and hydrolytic resistance. Proposed composition materials can be used in building, aircraft, automobile, aerospace, railway and other branches of industry.

EFFECT: improved and valuable properties of materials.
