Technical Field

The invention relates to the technical field of epoxy resin processing, in particular to efficient grinding equipment for epoxy resin preparation.

Background

The epoxy resin is a generic name of a polymer having two or more epoxy groups in a molecule. It is a polycondensation product of epichlorohydrin and bisphenol A or a polyol. Because of the chemical activity of the epoxy group, the epoxy group can be opened by a plurality of compounds containing active hydrogen, and the epoxy group is cured and crosslinked to form a network structure, so that the epoxy group is a thermosetting resin. The bisphenol A epoxy resin has the largest yield and the most complete variety, and the new modified variety is continuously increased and the quality is continuously improved. The molecular structure of the epoxy resin is characterized in that a molecular chain contains active epoxy groups, and the epoxy groups can be positioned at the tail ends, in the middle or in a ring structure. Because the molecular structure contains active epoxy groups, the epoxy groups can generate cross-linking reaction with various curing agents to form insoluble high polymers with a three-dimensional network structure. The macromolecular compounds containing epoxy groups in their molecular structures are collectively referred to as epoxy resins. Therefore, the coating is widely applied to various departments of national defense and national economy, and can be used for casting, dipping, laminating, adhesives, coatings and the like. Generally, massive epoxy resin is required to be crushed into powder so as to be added and used, however, the existing crushing and grinding device is simple in structure, cannot be completely crushed when in use, is poor in effect, needs manual frequent operation, and is slow in working efficiency, so that the problem that epoxy resin is prepared and is solved by using the efficient grinding equipment is necessarily provided.
