Example Embodiment

[0023] Example 1

[0024]Mix and stir bisphenol A epoxy resin, bismaleimide resin and cyanate ester resin in a mass ratio of 2:1:1 for 20 minutes, then heat up to 240°C to obtain a mixed resin. 20% silica sol was mixed and stirred at a mass ratio of 1:2 for 1 hour to obtain a modified epoxy resin; 32 g of diatomite was weighed and ground for 7 minutes, then passed through a 100-mesh sieve, the sieved powder was collected, and the sieved powder and silane The coupling agent KH-550 was mixed and stirred for 12 minutes at a mass ratio of 1:2. After stirring, a mixture was obtained. Continue to add glucose with a mass of 6% of the mixture and yogurt with a mass of 0.9% of the mixture into the fermenter. Sealed and fermented at 30 °C for 9 days. After the fermentation, the fermentation product was taken out, which is the modified diatomite powder; anhydrous ethanol and acetone were mixed and stirred for 10 minutes in an equal volume ratio to obtain a mixed solution. The mass ratio...

[0025] Example 2

[0026] Mix and stir bisphenol A epoxy resin, bismaleimide resin and cyanate ester resin in a mass ratio of 2:1:1 for 25 minutes, then heat up to 270°C to obtain a mixed resin. 20% silica sol was mixed and stirred at a mass ratio of 1:2 for 1.5 hours to obtain a modified epoxy resin; 36 g of diatomite was weighed and ground for 8 minutes, then passed through a 100-mesh sieve, the sieved powder was collected, and the sieved powder and Silane coupling agent KH-550 was mixed and stirred at a mass ratio of 1:2 for 14 minutes. After stirring, a mixture was obtained. Continue to add 6% of the mixture by mass glucose and 0.9% of the mixture's mass of yogurt into the mixture, put it into a fermentation tank, and at the temperature It is sealed and fermented at 35°C for 10 days. After the fermentation, the fermentation product is taken out, which is the modified diatomite powder; anhydrous ethanol and acetone are mixed and stirred for 11 minutes in an equal volume rat...

[0027] Example 3

[0028] Mix and stir bisphenol A epoxy resin, bismaleimide resin and cyanate ester resin in a mass ratio of 2:1:1 for 30 minutes, then heat up to 300°C to obtain a mixed resin. 20% silica sol was mixed and stirred at a mass ratio of 1:2 for 2 hours to obtain a modified epoxy resin; 40 g of diatomaceous earth was weighed and ground for 9 minutes, then passed through a 100-mesh sieve, the sieved powder was collected, and the sieved powder and silane The coupling agent KH-550 was mixed and stirred for 16 minutes at a mass ratio of 1:2. After stirring, a mixture was obtained. Continue to add glucose with a mass of 6% of the mixture and yogurt with a mass of 0.9% of the mixture into the fermenter. Sealed and fermented at 40°C for 11 days. After the fermentation, the fermentation product was taken out, which is the modified diatomite powder; anhydrous ethanol and acetone were mixed and stirred for 12 minutes in an equal volume ratio to obtain a mixed solution.

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 ...
