Embodiment 1

[0083] A kind of grouting material is prepared in this embodiment, and the specific raw material components are shown in Table 1, and the specific process is as follows:

[0084] S1. Heat the epoxy matrix at 60°C, then add reactive diluent and inorganic filler, and stir evenly at a speed of 250rpm to obtain component A;

[0085] S2. Mix all the raw materials of component B, and stir evenly at a speed of 300 rpm to obtain component B;

[0086] S3. Mix A component and B component according to the mass ratio to get the grouting material.

[0087] Examples 2-6 respectively prepared a grouting material, the difference from Example 1 is that the specific raw material components are different, and the specific components are shown in Tables 2-6.

Abstract

The invention discloses a grouting material, and a preparation method and application thereof, and belongs to the technical field of building materials. The grouting material comprises a component A and a component B; the component A is prepared from the raw materials: an epoxy matrix and a reactive diluent; the reactive diluent is at least two of butanediol glycidyl ether, allyl glycidyl ether and butyl glycidyl ether; the component B is prepared from the raw materials: a curing agent, a curing regulator, a coupling agent and a diluent; and the mass ratio of the component A to the component B is 100:(35-60). Due to the synergistic effect of all the components, the grouting material has the following advantages that the initial viscosity is low, the operable time is long, and the dry and wet bonding performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a grouting material, a preparation method and an application. Background technique [0002] Grouting material is a material that can be poured into the bottom layer or gap of the building to increase the strength of the ground, reduce the permeability of the ground, prevent the deformation of the ground, or repair the cracks of concrete buildings. [0003] With the development of technology, grouting materials have been popularized and applied in the fields of hydropower, construction, transportation and mining, and solved many engineering and technical problems. According to the performance and application classification of grouting materials, the commonly used grouting materials are roughly divided into anti-seepage and water-stop grouting materials and reinforcing and reinforcing grouting materials. Among them, the anti-seepage and water-type grouting m...
