[0005] A BMC composite material with high hardness and high compression resistance is obtained.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A glass fiber BMC alloy material, characterized in that the mass fraction of the preparation formula is:

[0008]

[0009] Preferably, the anti-ultraviolet absorber is one of UV-531, B770 light stabilizer or UV-X-1.

[0010] Preferably, the particle size of the fine calcium powder is 400-3000 mesh.

[0011] Preferably, the particle size of the fine metal is 120-1000 mesh, and the fine metal powder is one of iron powder, copper powder, aluminum powder or lead powder.

[0012] Preferably, the dispersant is BYK-W972 or BES-SF.

[0013] Preferably, the demoulding aid is BYK-P9065 or zinc stearate.

[0014] The beneficial effects of the present invention are:

[0015] The glass fiber BMC alloy material obtained by the present invention has better hardness and compression resistance after adding metal, does not deform or collapse in a long-term automobile rolling environment, and meets the demand for being used as a road facility material such as a manhole cover.
