Problems solved by technology

Among them, the epoxy resin material is a thermosetting material, but when the epoxy resin binder is not toughened, the cured product is relatively brittle, and the disadvantages of anti-stripping performance, low temperature resistance and impact resistance are limited, which limits its use in certain fields. The development and application of some civil engineering fields
Epoxy resin toughening can change the structural composition of the cured three-dimensional cross-linked system through chemical methods, endowing the three-dimensional cross-linked network with mobility, but the price of this special flexible epoxy resin material is more than three times the price of general epoxy resin. Increased application cost
At the same time, physical methods such as rubber elastomers, rigid

Embodiment Construction

[0043] The present invention will be described in detail through the following examples.

[0044] For the preparation method of A component of high-performance room temperature curing epoxy resin waterproof bonding material for road and bridge is as follows:

[0045] Heat the epoxy resin to 70°C, slowly add the toughening agent a after reaching the predetermined temperature, and keep stirring for 10 minutes after the addition of the toughening agent a. When the temperature drops to 50°C, add the diluent, stir for 5 minutes, and then ultrasonically remove the air bubbles in the 50°C environment for 20 minutes to facilitate subsequent operations. After cooling to room temperature, you can get the room temperature curing flexible epoxy resin waterproof adhesive for road bridges. A component.

[0046] Through the above preparation methods, three examples and three comparative examples are given this time, as shown in Table 1.

[0047] Table 1 Mass ratio of component A of room te...

Abstract

The invention discloses a normal-temperature curing flexibility epoxy resin waterproof binder for roads and bridges. The normal-temperature curing flexibility epoxy resin waterproof binder is characterized in that the waterproof binder is prepared from a component A and a component B, the component A is prepared form bisphenol A glycidyl ether epoxy resin, a toughening agent a, namely a rubber toughening agent, and an active diluent, and the component B is prepared form a polyamide curing agent and polyether amine curing agent mixed curing agent, a toughening agent b, namely a reacting toughening agent, and an amine accelerant, wherein the mass ratio of the component A to the component B during using is (100:35) to (100:50). The epoxy resin binder can be cured within 24 hours at the room temperature environment, and has high strength and high elasticity.

Description

technical field [0001] The invention relates to an epoxy resin adhesive, in particular to a normal temperature curing flexible epoxy resin waterproof adhesive for road bridges and a preparation method thereof. Background technique [0002] With the rapid development of highway construction in my country, the construction of long-span bridges is also increasing year by year. The bridge deck pavement can effectively prevent the wheels from directly wearing the bridge deck and spreading loads, and at the same time provide a smooth, non-slip and comfortable contact surface for vehicles. The bridge deck pavement is divided into pavement main body, waterproof layer and adhesive layer, among which, the waterproof adhesive layer is mainly responsible for connecting the pavement main body and the surface of the bridge body in the bridge pavement to make it a whole and improve the stress of the bridge. At the same time, it prevents moisture from invading the bridge body, destroying th...
