The invention discloses a high-strength
epoxy encapsulated
resin adhesive with single-component diverting and stabilizing functions and a preparation method of the high-strength
epoxy encapsulated
resin adhesive. According to the technical scheme, the high-strength
epoxy encapsulated
resin adhesive with the single-component diverting and stabilizing function is prepared from, by weight, 40 to 60 parts of epoxy resin, 0.05 to 0.5 part of 2,6-di-tert-butyl-4-methylphenol, 5 to 15 parts of a
toughening agent, 40 to 60 parts of a filling material, 3 to 15 parts of a curing agent, 0.5 to 5 parts ofa curing accelerator, and 0.5 to 1 part of a stabilizing agent; wherein the filler is a composition of
fiber powders in different length-to-
diameter ratios according to the following ratio: 10-30% oflength-to-
diameter ratio being (1-10):1, 40-60% of length-to-
diameter ratio being (10-20):1, and 10-30% of length-to-
diameter ratio being (20-30):1. According to the present invention, the combination of the
fiber powders with different contents and different length-diameter ratios is used, and the rheological property of the encapsulation
adhesive is controlled by using the different mutual winding degrees of the
fiber powders with different length-diameter ratios in the epoxy resin, such that the prepared product has advantages of
rheology stability and high strength.
