Abstract

The invention discloses a thermally conductive and insulating composite material. The thermally conductive and insulating composite material comprises the following components: 100 parts of resin, 3 parts of an initiator, 1 part of a promoter, 0.5 parts of a dispersant, 2 parts of a coupling agent, 5-150 parts of hollow beads, and 40-120 parts of a fire retardant. The thermally conductive and insulating material has the beneficial effect that after a proper amount of liquid fire retardant is added, under condition that the density and intensity change of the buoyancy material is little, the refractiveness (oxygen index is greatly increased) is greatly increased.

Description

technical field [0001] The invention belongs to the field of composite materials. Specifically, the invention relates to an epoxy resin composite material with good flame retardancy. Background technique [0002] Usually the high-strength buoyancy material is resin-filled hollow lightweight microbeads, and through a series of defoaming, [0003] Made by curing process, the resin is flammable, its overall fire resistance is poor, and its oxygen index is low. [0004] However, when high-strength buoyancy materials are used in some occasions, higher fire resistance is required. Contents of the invention [0005] The invention provides a heat-conducting buoyancy composite material with flame-retardant performance. [0006] Technical scheme of the present invention is: [0007] A thermally conductive buoyancy composite material, the mass components of which are as follows: [0008] Resin: 100 parts; [0009] Initiator: 3 parts; [0010] Accelerator: 1 part; [0011] Dis...
