Abstract

The present invention relates to glued plate and is especially one kind of sound box casing plate and its production process. Its material includes unsaturated resin 30-40 wt%, aluminum powder 60-70wt%, promoter 0.2-1 wt%, curing agent 0.8-2 wt% and proper amount of pigment slurring. Sound box produced with the casing plate is bright, smooth and hard; and compared with that of wood, it has high damp, clear sound background, less distortion, less vibration, high sealing performance and low cost and is suitable for industrial production.

Description

technical field [0001] The invention relates to an artificial plywood, in particular to a sound box shell board and a manufacturing method thereof. Background technique [0002] Existing sound box shell boards are basically wooden boards, the surface is not smooth and dark, easy to be affected by moisture, damaged by box vibration, and poor in sealing. Contents of the invention [0003] Therefore, the object of the present invention is to provide a sound box shell plate with smooth and bright appearance, moisture-proof and small box vibration and its manufacturing method. [0004] The first object of the present invention is achieved in this way. [0005] A speaker shell board, which includes the following raw materials in weight percentage: 30%-40% of unsaturated resin, 60%-70% of aluminum powder, 0.2%-1% of accelerator, 0.8%-2% of curing agent, and an appropriate amount of color paste . [0006] Above-mentioned purpose also can be done following further improvement. ...
