Abstract

The invention discloses a quick-setting epoxy grouting mortar suitable for summer first-aid repair construction. The quick-setting epoxy grouting mortar is formed by mixing of a resin component A, a curing agent component B and a bone powder component C in a mass ratio of 1:(0.2-0.26):(5-7) during use. Specifically, the component A comprises the following components by weight: 100 parts of modified epoxy resin, 1-15 parts of an alcohol ether composite diluent, 1-3 parts of a coupling agent, and 0.5-3 parts of a rheological agent; the component B comprises the following components by weight: 16-23 parts of a modified polyamine curing agent, and 1-3 parts of an accelerator; and the component C comprises the following components by weight: 1-23 parts of dolomite powder, 15-46 parts of bariumsulfate powder, 10-121 parts of cement, 385-588 parts of sea sand, and 0.1-1.5 parts of a defoamer. The quick-setting epoxy grouting mortar provided by the invention has the technical characteristicsof short curing time, high hour strength, and no flash polymerization during high temperature construction, at the same time is non-toxic and harmless, and is simple to prepare, and is widely applicable to concrete structure repair with quick-setting and early strength requirements and construction of installation and anchoring projects, especially suitable for summer repair construction.

Description

technical field

[0001] The invention belongs to the technical field of emergency repair construction of construction engineering, and in particular relates to a quick-setting epoxy perfusion mortar suitable for emergency repair construction in summer. Background technique

[0002] Epoxy perfusion mortar is a kind of perfusion gravity mortar material mixed with epoxy resin, curing agent and bone powder in a certain proportion. Epoxy perfusion mortar has excellent mechanical properties and bonding properties, high early strength, and is widely used in defect repair and reinforcement of concrete engineering structures; epoxy mortar also has excellent flexural and fatigue resistance, and is often used in bridge supports, Anchoring of equipment foundations, grouting of supporting substrates of large equipment under dynamic load conditions such as rails and door cranes.

[0003] The current repair materials mostly use finished cement-based grouting materials, which have good cons...
