Problems solved by technology

[0006] In view of the shortcomings of the above-mentioned epoxy grouting materials, such as fast heat release and fast curing, which cannot meet the needs of large-volume foundation grouting, the epoxy resin, curing agent and filler were screened and compounded to improve the fluidity and final performance of the material. Intensity, while slowing down the curing speed and slowing down the heat release during the curing process, so as to meet the construction needs of large-volume grouting, that is, good fluidity, uniform curing, and does not contain volatile substances such as organic solvents that are harmful to the human body, and does not contain Small molecular substances such as inactive tougheners that will overflow later

Embodiment 1

[0041] The high-strength and high-fluidity epoxy resin grouting material of the present embodiment is composed as follows:

[0042] Table 1

[0043]

[0044]

[0045] The mass ratio of component A, component B and component C is 127:38:801.2, that is, 1:0.3:6.3.

[0046] The preparation method is as follows:

[0047] Take each component A and mix to obtain component A;

[0048] Take the B components and mix them to obtain the B components;

[0049] Take the C components and mix them to obtain the C components.

[0050] During on-site construction, first mix components A and B evenly, and then add component C to complete the grouting construction. After construction, no maintenance is required. 20°C, 3-day compressive strength is 70MPa, see Table 4 below for specific properties (refer to the "Cement Mortar Strength Test" GB / T17671-1999 standard for testing).

The high-strength high-mobility epoxy resin grouting material comprises componentA, component B and component C; the component A comprises, by weight, 100 parts of epoxy resin, 5-30 parts of a diluent, 1-2 parts of a coupling agent and 0.5-2 parts of a defoaming agent; the component B comprises, by weight, 5-15 parts of aliphatic amide polyamine, 0-10 parts of aliphatic amine containing aromatic rings, 5-20 parts of alicyclic diamine, 0-10 parts of a polyether amine curing agent, and 0-10 parts of 593 curing agent; the component C comprises, by weight, 1-5 parts of a thixotropic agent, 0-100 parts of quartz sand 3-5 mm, 0-300 parts of quartz sand 1-3 mm, 0-400 parts of quartz sand 0.5-1 mm, 100-400 parts of quartz sand 40-70 mesh, 150-400 parts of flyash, and 0-100 parts of mineral waste. The high-strength high-mobility epoxy resin grouting material has high strength and mobility; by adjusting powder ratio and addition, the high-strength high-mobility epoxy resin grouting material can adapt to different grouting thicknesses; the performance of the high-strength high-mobility epoxy resin grouting material can be improved, and the requirement for better simplicity and environmental friendliness in production can also be met.

Description

technical field [0001] The invention belongs to the technical field of epoxy resin materials, and relates to a high-strength and high-fluidity epoxy resin grouting material and a preparation method thereof. Background technique [0002] Epoxy resin has the characteristics of high bonding strength, good mechanical properties, and good corrosion resistance. Therefore, it is widely used in many fields such as electronics, machinery, and construction as adhesives, coatings, and grouting materials. For example, epoxy resin, as a grouting material, is widely used in large and medium-sized enterprises for equipment installation, bolt anchoring, and reinforcement and reconstruction of building structures. [0003] With the development of epoxy resin grouting material technology, higher requirements are put forward for the strength, fluidity and other performance indicators of the material. At the same time, high requirements are put forward for the environmental protection performa...
