Problems solved by technology

The flame-retardant ABS material mainly improves the flame-retardant performance of the lead-acid battery shell, but still does not solve the problem that the ABS material has poor impact resistance and is easily broken when a collision occurs; in addition, the preparation method of the material is to combine each component Add to the high-speed mixer according to the proportion and mix evenly, and then use the twin-screw extruder to granulate
The preparation method starts with high-speed mixing, which is just a simple physical mixing. In the subsequent extrusion, the components, especially the fine inorganic particles, are still not uniformly dispersed, and it is difficult to mix evenly with the resin matrix, and the mixing uniformity of the material is poor.
