Problems solved by technology

Although epoxy plastics have the advantages of strong adhesion, good chemical stability, and good mold resistance, but with the continuous improvement of design and use requirements, the existing commercially available epoxy plastics can no longer meet people's requirements.
Especially in long-term use, epoxy plastics are prone to aging, wear resistance and other adverse phenomena, which seriously affect the use of epoxy plastic products, and need to be continuously improved

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a modified plastic particle with stable mechanical properties and a preparation process. Background technique [0002] Plastic has the characteristics of light weight, no rust, good insulation and so on, so it is widely used in daily life. Epoxy plastic is a plastic based on epoxy resin. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, middle or part of the molecular chain. ring structure. Due to the active epoxy groups in the molecular structure, they can cross-link with various types of curing agents to form insoluble. A non-melting high polymer with a three-way network structure. Epoxy plastic is used for some computer keyboards and the bottom of toy cars. Although epoxy plastics have the advantages of strong adhesion, good chemical stability, and good...
