Abstract

The invention discloses a method for processing EPP loudspeaker box cone paper. In parts by weight, the EPP loudspeaker box cone paper is prepared from the following raw materials: 20-30 parts of EPP,1-4 parts of short fibers, 45-65 parts of paper pulp, 4-6 parts of fluorophlogopite powder, 3-7 parts of barium sulfate, 1-5 parts of boron carbide, 1-5 parts of silicon carbide, 2-8 parts of siliconnitride, 10-20 parts of aluminum oxide, 1-5 parts of adhesive and 5-9 parts of foaming agent; and specific steps are as follows: adding the paper pulp to a beater, adding water to dilute and beating;preparing body paper; and moulding a finished product of the EPP loudspeaker box cone paper. The EPP loudspeaker box cone paper provided by the invention has the advantages of high temperature resistance and good corrosion resistanc.

Description

technical field [0001] The invention relates to the field of sound box drum paper, in particular to a processing method of EPP sound box drum paper. Background technique [0002] Traditional drum paper uses paper or plastic parts. Because the drum paper needs to achieve a certain sound effect, it needs a certain thickness and has strict requirements on the weight of the material. Therefore, it cannot be achieved through traditional paper or plastic parts, and then developed the EPS speaker drum paper; the existing EPS speaker drum paper has certain disadvantages when used. First of all, EPS has shortcomings such as not being resistant to high temperature, acid and alkali, etc., which is easy to cause corrosion or high temperature damage, especially for high-end car speakers. The high temperature is 103 degrees, and the automotive field is prone to oil pollution, or acid and alkali corrosion. For this reason, we propose a processing method for EPP speaker drum paper.
