Abstract

The invention relates to a low-density halogen-free flame retardant type high-strength composite material and a preparation method thereof. The low-density halogen-free flame retardant type high-strength composite material is characterized in that the composite material comprises the following components in parts by mass according to 300 mass parts: 70-100 parts of multifunctional epoxy resins, 20-30 parts of phenoxy resins, 40-60 parts of phosphorus-containing curing agent, 0.05-0.5 part of imidazole accelerant, 0.1-0.6 part of ammonia accelerant, 10-60 parts of porous silicon dioxide, 10-60 parts of hollow microspheres, 0.3-5 parts of amine terminated coupling agents and 3-20 parts of ethanol, wherein the substance components are mixed according to the proportion and are uniformly dispersed to prepare the low-density halogen-free flame retardant type high-strength composite material. The low-density halogen-free flame retardant type high-strength composite material is simple in process, low in cost and wide in application prospect in fields of splicing sheets and composite materials; and the prepared composite material is low in density, halogen-free flame retardant and high in strength.

Description

technical field [0001] The invention relates to a low-density halogen-free flame-retardant tree-type high-strength composite material and a preparation method thereof. Resin composition and method for making adhesive sheets and high-strength laminated composites using it. It belongs to the field of reinforced composite materials. Background technique [0002] Composite material is a new type of material that is composed of two or more heterogeneous, heterogeneous, and heterogeneous materials, and has a composite effect, commonly known as copper clad laminate. Composite materials generally consist of a matrix and reinforcements. Composite materials are rationally designed, and through the selection of raw materials, the distribution design of each component and the guarantee of process conditions, the advantages of the original components and materials are complementary, thus showing excellent comprehensive performance. [0003] For the vast majority of composite materials...
