Preferably, to account for the content in described organic solvent be 50% ~ 67% to described ethanol.
Preferably, to account for the content in described organic solvent be 33% ~ 50% to described glycerine.
Preferably, the water content of described ethanol is less than or equal to 10%.
The present invention also further provides the preparation method of a kind of loudspeaker with halogen-free scaling powder, the method is: weighing rosin and ethanol in proportion, pour into successively in container, stir rosin and ethanol in container, until rosin dissolves fully, pour load weighted glycerine into container again, the solution in stirred vessel mixes rosin, ethanol and glycerine, and the described loudspeaker that is stirred is preserved with the halogen-free scaling powder sealing.
Because technique scheme is used, the present invention compared with prior art has following advantages: the present invention adopts the Halogen material as raw material, has met the environmental protection demand of product; The content of solute rosin can be adjusted according to the needs of different product, and Technological adaptability promotes greatly; Adopt the solvent of two kinds of solvents as scaling powder, adjust viscosity and the evaporation rate of scaling powder by the ratio of regulating two kinds of solvents, repeat to meet the demand of production line.
