Problems solved by technology

[0003] The above-mentioned fiber materials do not have the characteristics of high temperature resistance, corrosion resistance, and solvent resistance after setting, nor do they have the characteristics of long-term use at a temperature of about 250±5 degrees, not easily deformed at high temperatures, and have the characteristics of fast heat dissipation and good ventilation
So it is not suitable for voice coil frame material

Embodiment 1

[0013] The manufacturing method of the voice coil frame material provided in this embodiment is to dip the coil into the glass fiber cloth with high temperature resistant glue, wherein the concentration of the high temperature resistant glue is 212MPA.S, and 0.35% red pigment is added to the high temperature resistant glue. Bake the glass fiber cloth soaked with high-temperature-resistant glue in a baking oven with a temperature of 290°C, and pass through the first baking oven with a length of 4 meters at a speed of 1.5 meters per minute to obtain the first glued cloth. fiberglass material;

[0014] The glass fiber material after the first gluing is evenly coated with self-adhesive adhesive glue, the concentration of the glue is 425MPA.S, and the self-adhesive adhesive glue is coated in an oven at a temperature of 202 degrees. Baking, passing through the second baking oven with a length of 4 meters at a speed of 2 meters per minute, and finally producing a red voice coil skele...

Embodiment 2

[0016] The manufacturing method of the voice coil frame material provided in this embodiment is to dip the coil into the glass fiber cloth with high temperature resistant glue, wherein the concentration of the high temperature resistant glue is 221MPA.S, and 0.4% green pigment is added to the high temperature resistant glue. Bake the glass fiber cloth soaked with high-temperature-resistant glue in a baking oven with a temperature of 290°C, and pass through the first baking oven with a length of 4 meters at a speed of 1.5 meters per minute to obtain the first glued cloth. fiberglass material;

[0017] Coat the glass fiber material after the first gluing evenly with self-adhesive adhesive glue, where the concentration of the glue is 435A.S, and bake the coated self-adhesive adhesive glue in an oven at a temperature of 222 degrees , passing through the second baking oven with a length of 4 meters at a speed of 2 meters per minute, and finally produced the green voice coil skeleto...

Embodiment 3

[0019] The manufacturing method of the voice coil frame material provided in this embodiment is to dip the coil into the glass fiber cloth with high temperature resistant glue, wherein the concentration of the high temperature resistant glue is 232MPA.S, and 0.37 yellow pigment is added to the high temperature resistant glue. Bake the glass fiber cloth soaked with high-temperature-resistant glue in a baking oven with a temperature of 290°C, and pass through the first baking oven with a length of 4 meters at a speed of 1.5 meters per minute to obtain the first glued cloth. fiberglass material;

[0020] The glass fiber material after the first gluing is evenly coated with self-adhesive adhesive glue again, and the concentration of the glue is 445MPA. Bake, and pass through the second baking oven with a length of 4 meters at a speed of 2 meters per minute, and finally produce a yellow voice coil skeleton material.

Abstract

The invention discloses a manufacturing method for a voice coil framework material. The manufacturing method comprises the following steps of: wetting and immersing high-temperature resistant glue in glass fiber cloth, wherein the concentration of the high-temperature resistant glue is 200-250MPA.S; roasting the glass fiber cloth and wetted and immersed with the high-temperature resistant glue in a roasting oven with the temperature of 290+ / -5DEG C; uniformly coating self-adhesive adhesion agent glue on a fiber material again, wherein the concentration of the glue is 400-500MPA.S; roasting the fiber material coated with the self-adhesive adhesion agent glue in a roasting oven with the temperature of 200+ / -5DEG C; and finally obtaining the voice coil framework material. The voice coil framework material manufactured by the method has the advantages of high temperature resistance and favorable permeability.

Description

technical field [0001] The invention relates to an article for a voice coil, in particular to a method for making a voice coil skeleton. Background technique [0002] The Chinese Invention Patent No.: 200910032195.7 discloses a high temperature resistant glass fiber cloth and its manufacturing method. Using ordinary non-alkali glass fiber cloth as raw material, dewaxing treatment is carried out in a continuous dewaxing furnace. After treatment, the paraffin-type pretreatment agent on the surface of the non-alkali glass fiber cloth is completely removed, and the glass fiber is exposed. Put the dewaxed non-alkali glass fiber cloth into the tank, and use an acid-resistant pump for circulating stirring and auxiliary bubbling stirring to strengthen the ion exchange process. Afterwards, spray the surface of the cloth to remove residual acid on the surface, then soak it in clean water, and wash it under the flow of clean water. After washing with water, it is dried again in a con...
