Embodiment 1

[0038] Preparation of polyester resin sheet: Add 50kg of dicyclopentadiene, 18kg of hydrogen peroxide, 0.3kg of phenol-modified tungsten hexachloride and 2.7kg of glass fiber into the reaction kettle at a temperature of 30°C and stir Mix all the above materials evenly, then increase the temperature of the reactor to about 160°C, and add 4kg of brominated polystyrene, whose brand is PBS-64HW, 3kg of nano-silica, and 2kg of potassium oxide, while continuing to stir. Continue to stir and react for about 6 hours to obtain a high temperature resistant dicyclopentadiene unsaturated polyester resin. Then process the dicyclopentadiene unsaturated resin into 2mm unsaturated polyester resin sheets for subsequent use.

[0039] Pre-impregnated glass fiber cloth: take 3 kg of iron powder and copper powder mixture with a fineness of 500 mesh, then mix the above mixture with 15 kg of dicyclopentadiene unsaturated resin, and then add 2 kg of glass fiber cloth woven from glass fiber pre-impre...

Abstract

The invention provides a high-performance fiberglass reinforced plastic composite material and a preparation method thereof. The high-performance fiberglass reinforced plastic composite material consists of the following components in percentage by weight: 50 to 80 percent of dicyclopentadiene, 10 to 30 percent of hydrogen peroxide, 1 to 3 percent of potassium oxide, 0.1 to 0.5 percent of tungsten hexachloride, 1 to 5 percent of fire retardant, 2 to 4 percent of nano filler, 1 to 8 percent of glass fiber and 1 to 3 percent of metal filler. Hydrogen peroxide, fire retardant and potassium oxide are added into dicyclopentadiene, so that the softening temperature of the fiberglass reinforced plastic composite material can be increased and is more than 150 DGE C.

Description

[0001] technical field [0002] The invention relates to a composite material and a preparation method thereof, in particular to a high-performance polyester glass composite material and a preparation method thereof. [0003] Background technique [0004] Polyester fiberglass composite material generally refers to a chemical composite material obtained by reinforcing unsaturated polyester resin with glass fiber. Polyester fiberglass composite material has the advantages of light weight and hardness, non-conductivity, and high mechanical strength. However, ordinary polyester FRP has low bending strength and low softening point below 90°C. It is difficult to meet the requirements of some special occasions, such as aerospace, automobile, construction, fitness equipment, etc. [0005] Contents of the invention [0006] To sum up, it is necessary for the present invention to provide a high-performance polyester fiberglass composite material with a high softening temperature...
