Embodiment 1
[0029] A magnesium-aluminum alloy composite plate with sound-absorbing and good mechanical quality, comprising upper and lower layers of magnesium-aluminum alloy plates and a reinforced filling layer adhered and fixed between the two layers of magnesium-aluminum alloy plates; the reinforced filling layer consists of the following parts by weight Made of materials: 55 parts of epoxy resin, 6 parts of C9 petroleum resin, 3 parts of urea-formaldehyde resin, 4 parts of isophthalic unsaturated polyester resin, 4 parts of reinforced basalt fiber, 0.2 parts of leveling agent, 1 part of defoamer, 0.5 parts of film former, 0.6 parts of stabilizer.
[0030] Further, the preparation method of the described reinforced basalt fiber comprises the following steps:
[0031] (1) First put the basalt fiber into the freezer for freezing treatment, and take it out after 4 hours for later use;
[0032] (2) Take out the basalt fiber treated in step (1) and put it into the incubator, control the va...
