Abstract

The invention discloses a wind-power class bi-component epoxy adhesive and a preparation method thereof. The epoxy adhesive is made from a main component A mainly consisting of epoxide resin and a filler and a curing agent component B and characterized in that the component A, according to percentage by weight, contains 50 percent to 68 percent of acrylic acid modified epoxide resin, 1 percent to 10 percent of high-property heat filler, 2 percent to 10 percent of epoxide diluter, 10 percent to 25 percent of thixotropic agent and 0.5 percent to 12.5 percent of additive, and the component B is divided into aliphatic amine, polyetheramine, alicyclic amine mixed-type general curing agent; and the mixing proportion of the component A and the component B is 100:30-100:50 according to portions by weight. The invention can improve exothermic peak temperature property during the curing reaction of epoxide resin adhesive and the toughness of the epoxy adhesive, thus being applicable to the cementation of large-scale composite material structural pieces, particularly meeting the requirements for low exothermic peak temperature in wind-power leaf pectization technology.

Description

Technical field: [0001] The invention relates to the technical field of polymer material adhesives, in particular to a wind power-grade two-component epoxy adhesive and a preparation method thereof, which are mainly used in the bonding of large-scale composite material structures, and are especially suitable for the mold-clamping bonding of wind power generation blades . Background technique: [0002] Wind energy is a kind of green energy sourced from nature, pollution-free, and the fastest growing in the world. At present, the wind power industry is in its infancy, and has the conditions for rapid development of the wind power industry, and a large number of enterprises manufacturing wind turbine blades have emerged, and epoxy resin adhesives are usually required to manufacture wind turbine blades with composite materials. [0003] In addition to the characteristics of high thixotropy, long pot life, and high mechanical strength of the cured product, epoxy resin adhesives ...
