Description

Technical field: [0001] The invention relates to an epoxy resin adhesive, in particular to a novel high temperature resistant epoxy resin structural adhesive and a preparation method thereof. Background technique: [0002] Structural adhesive is a kind of construction adhesive with polymer synthetic material as the main component, and the main type is epoxy resin adhesive. Structural adhesives have the characteristics of great cohesion and high bonding strength after curing. At first, building structural glue was used for reinforcement projects, mainly used for high-strength, fast-fixing equipment anchor bolts, bonding embedded parts connected with concrete, tie bars and granite decorative flakes, marble walls, and repairing airstrips and plugging etc., but now it is mainly used for the maintenance and reinforcement of lost or undamaged reinforced concrete structures, special building structures, foundation construction of bridge piles, reinforcement and maintenance of high...
