Abstract

The invention discloses an environment-friendly foam material with heat conductivity and a preparation method thereof. The environment-friendly foam material with heat conductivity comprises, by weight, 20-30 parts of polyethylene, 20-30 parts of poly-biooil polyether polyols, 40-55 parts of epoxy resin, 10-70 parts of a heat-conducting filler, 5-8 parts of a dispersant, 1-3 parts of a flame retardant, 1-10 parts of an anti-aging system, 1-3 parts of a plasticizer, 3-5 parts of a foam stabilizer, and 1-15 parts of a foaming system. The environment-friendly foam material with heat conductivityand the preparation method thereof have the advantages that inner cells are uniform, foaming rate is high, heat conductivity coefficient is high, controlling and production are benefited, the production cost is reduced, epoxy resin enables residual ethanolamine in the poly-biooil polyether polyols to react such that residue is further decreased, and the environment can be protected as epoxy resinhas high degradability.

Description

Technical field [0001] The invention relates to the fields of foam, heat conduction, electronics industry and the like, and specifically relates to an environmentally friendly foam material with heat conduction performance and a preparation method thereof. Background technique [0002] Thermal conduction is the phenomenon of heat transfer when there is no macroscopic movement in the medium. It can occur in solids, liquids and gases, but strictly speaking, only in solids is pure heat conduction, and fluids are in a static state. , Which also produces natural convection due to the density difference caused by the temperature gradient. Therefore, thermal convection and heat conduction occur simultaneously in the fluid. In the field of electronics industry, heat conduction has always been an important process in the electronics industry, and the operating temperature of components is often an important basis for reliability. In particular, the assembly of microelectronics is becomin...
