Abstract

The invention relates to a composite plate pre-embedding adhesive and a preparation method thereof. During use of the composite plate pre-embedding adhesive, a first component and a second component are mixed according to a weight ratio of (2 to 4) to 1; the first component is prepared from the following constituent raw materials in parts by weight: 20 to 45 of epoxy resin, 1 to 10 of modified epoxy resin, 1 to 10 of activated diluents, 5 to 20 of reinforcing filler, 20 to 70 of a flame retardant and 0.3 to 10 of a thixotropic agent; the second component is prepared from the following constituent raw materials in parts by weight: 50 to 90 of a toughening curing agent, 10 to 20 of a hardening curing agent, 0.3 to 1 of a coupling agent and 0.3 to 15 of a thixotropic agent. Compared with theprior art, the composite plate pre-embedding adhesive has the advantages of extremely high rigidity, toughness and the like.

Description

technical field [0001] The invention relates to a pre-embedded glue and a preparation method thereof, in particular to a composite board pre-embedded glue and a preparation method thereof. Background technique [0002] With the continuous development of high-speed rail technology, a large number of sandwich composite structural materials are widely used, and the middle of a large number of sandwich composite structural materials is generally a honeycomb structure, and the overall plate has excellent tensile and compressive bending strength. The screw cannot achieve the desired strength, mainly because the hollow structure cannot cover the screw so that the screw is in a suspended state. The conventional solution is to embed pre-embedded solid blocks (aluminum blocks, bakelite blocks, etc.) The board is made by composite, it is difficult to change the structure, and if the position of the threaded hole is not accurate, there will be defects in the product delivery, and some ...
