Abstract

The invention relates to the technical field of preparation of reinforcing materials for building structures, particularly to a preparation method of a high-temperature-resistant anchoring glue. According to the present invention, a modified epoxy resin is used as a matrix, modified diatomaceous earth powder and modified carbon fiber are used as filler reinforcing agents, cyclohexanone peroxide isused as an initiator, ethylenediamine is used as a curing agent, and benzyl triethyl ammonium chloride, benzyl alcohol and salicylic acid are mixed to form a curing accelerator, such that the anchoring glue with high mechanical property and high-temperature resistance is prepared; the epoxy resin is modified with a bismaleimide resin and a cyanate resin so as to improve the mechanical property ofthe epoxy resin and enhance the high-temperature resistance of the epoxy resin; the diatomaceous earth powder is modified with a silane coupling agent; and the carbon fiber is modified through nitricacid-ultrasonic synergistic treatment so as to improve the mechanical property of the anchoring glue, such that the mechanical strength and the high-temperature resistance of the anchoring glue are further improved, and the application prospects are broad.

Description

technical field [0001] The invention relates to the technical field of preparation of reinforcement materials for building structures, in particular to a preparation method of a high-temperature-resistant anchor glue. Background technique [0002] Anchor glue, commonly known as planting glue, is mainly used in the construction industry to strengthen the connection between concrete and steel bars. Reinforced concrete structures occupy an extremely important position and a considerable amount in my country's construction. With the development of my country's economic construction and industrial structure, anchoring glue has been rapidly developed and widely used in recent years. [0003] Anchor glue is a building structure bonding and strengthening material made of special synthetic resin, curing agent, curing accelerator, filling material and various chemical additives. Among the most commonly used polymers are epoxy resins, unsaturated polyester resins, acrylic resins, and ...
