Technical Field
The utility model relates to a technical field of epoxy production especially relates to an epoxy composition production is extruded and is used blade combination.
Background
The basic process for producing the epoxy resin composition is as follows: the raw materials are premixed, extruded and mixed, cooled and crushed, screened by a vibrating screen and magnetically separated, then put into a storage bin and then post-mixed to finish the process. During the whole production process, the reaction and material conveying are basically carried out in a closed environment, and the aim is to reduce the pollution and the performance influence of the external environment on the epoxy resin composition as much as possible.
In the production process, a production link, namely extrusion mixing, is to extrude and knead the epoxy resin composition to promote the epoxy resin composition to generate partial crosslinking and generate polymerization reaction, and for the composition with higher resin content of general EOCN, the conventional shearing blade combination can achieve the chemical heat release point and maintain the continuous heat release reaction. However, for the spherical silicon dioxide epoxy resin composition with high filler and low particle size, the conventional shearing blade combination and the preheating temperature cannot reach the chemical heat release point, the composition cannot generate polymerization reaction, the reaction can be promoted by increasing the number of the shearing blade groups, but the production efficiency is low, and the requirements of production and client packaging use cannot be met.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides an embodiment: an extrusion blade assembly for producing an epoxy resin composition comprises a plurality of blade assemblies 1;
a plurality of blade assemblies 1 are coaxially connected in series to form a blade member 2, and the center of the blade member 2 is connected with a rotating shaft 3;
the blade assembly 1 has a circular arc triangle cross section.
According to the above technical solution, the blade assembly 1 comprises a plurality of sets of blades 11, compared with the prior art in which the blades 11 are arranged in a staggered manner, the staggered arrangement means that the opposite surfaces of two adjacent blade assemblies 1 are not completely overlapped, and the staggered angle between the blade assemblies 1 is set to 30 °, so that the length of shearing and the whole shearing area can be increased, thereby enhancing the shearing force between the fillers with ultrafine particle sizes, the fillers and resins, and other different materials, fillers and resins, so as to achieve the chemical heat release point of the epoxy resin composition, promote the cross-linking polymerization reaction, and form a stable state in the barrel to maintain the continuous reaction of the subsequent feeding composition, form a stable molding material at the discharge end, and the better the mixing and kneading effects of the epoxy resin composition when the shearing length is longer, the homogenizing effect is better.
