[0059] In the fourth aspect, an embodiment of the present invention provides a method for preparing a two-color injection molded part as described above, see figure 1 ,include:
[0060] Step 1) Injection molding the first material to obtain the first color layer;
[0061] Step 2) Injecting a second material onto at least one side of the first color layer to obtain the second color layer.
[0062] The embodiment of the present invention provides a method for preparing a two-color injection molded part. By using a modified resin as a two-shot material, since the modified resin uses acrylic resin / montmorillonite nanocomposite microspheres as a flow modifier, on the one hand , the acrylate resin itself has a low melting point and acts as a flow modifier; on the other hand, the acrylic resin / montmorillonite nanocomposite microspheres can be better dispersed in the In the resin matrix, rolling friction is formed between the resin matrix, which greatly reduces the friction between ...
