Flame-retardant phenol formaldehyde epoxy composite material

Abstract

The invention relates to a flame-retardant phenol formaldehyde epoxy composite material, belonging to the technical field of high polymer materials. The flame-retardant phenol formaldehyde epoxy composite material comprises 20-23 parts of phenol formaldehyde epoxy resin, 12-16 parts of epoxy resin, 6-9 parts of phenol formaldehyde resin, 2-4 parts of curing agent, 0.6-1.1 parts of metal oxide, 0.8-1.2 parts of releasing agent, 18-21 parts of mineral filler, 0.5-0.9 part of interface compatilizer, 11-13 parts of reinforcing fiber and 9-13 parts of compound flame retardant. The flame-retardant phenol formaldehyde epoxy composite material has the advantages of favorable heat resistance and high strength, and is convenient for molding. The test proves that the bending strength is 88 MPa, the heat-deformation temperature is 240 DEG C, and the flame retardancy reaches Grade V-0 (UL-94-V-0 1.6mm).

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant phenolic epoxy composite material. Background technique [0002] Because novolac epoxy composite materials have good comprehensive properties, they are widely used by people, but novolac epoxy materials themselves cannot provide good flame retardancy. Therefore, it is necessary to improve their flame retardancy and at the same time ensure that they have Properties such as heat deformation resistance, bending strength, etc. Contents of the invention [0003] The task of the present invention is to provide a flame-retardant novolak-epoxy composite material which not only has good mechanical properties but also has outstanding flame-retardant properties. [0004] The object of the present invention is achieved like this, a kind of fire-retardant novolac epoxy composite material, comprises following component: [0005] [0006] In a spec...
