Problems solved by technology

[0002] At present, the adhesive used in the anchorage system is mainly unsaturated resin glue. Unsaturated resin glue has the advantages of fast curing speed, short early strength time, and good adhesion. However, unsaturated resin glue has a strong smell when used, and the cured Colloidal texture is brittle and hard, insufficient toughness, and poor weather resistance, high temperature aging resistance

Abstract

The invention provides an anchor tool structural adhesive and a preparation method thereof. The anchor tool structural adhesive is prepared from a component A and a component B through mixing in a mass ratio of 2 to 1, wherein the component A contains bisphenol A epoxy resin, bisphenol F epoxy resin, a diluent, a toughening agent, a thixotropic agent, a coupling agent and a filling; and the component B contains a polyamide curing agent, the thixotropic agent, the coupling agent and the filling. The anchor tool structural adhesive is good in fluidity, thixotropy and convenient to construct and does not easily flow.

Description

technical field [0001] The invention relates to the field of structural adhesives, in particular to an anchorage structural adhesive and a preparation method thereof. Background technique [0002] At present, the adhesive used in the anchorage system is mainly unsaturated resin glue. Unsaturated resin glue has the advantages of fast curing speed, short early strength time, and good adhesion. However, unsaturated resin glue has a strong smell when used, and the cured The colloid is brittle and hard, with insufficient toughness, and poor weather resistance and high temperature aging resistance. [0003] Epoxy resin adhesives have excellent process performance, mechanical properties, bonding performance, good weather resistance, low shrinkage rate, and low price, and are widely used in national defense, civil and other engineering fields. Applied to reinforcement materials, durability is a necessary performance, so it is very necessary to develop anchorage structural adhesives...
