Description

Technical Field

[0001] The invention relates to the technical field of resin production, in particular to a mechanical automatic discharging mechanism for resin production. Background Art

[0002] Epoxy resin refers to an organic polymer compound containing two or more epoxy groups in its molecule. Except for a few exceptions, their relative molecular mass is not high.

[0003] The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, which can be located at the end, in the middle or in a ring structure. Due to the presence of active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble, infusible polymers with a three-dimensional network structure.
