Problems solved by technology

ZL 201210311463.0 and ZL 201510153654.2 proposed a high-strength and fast-curing epoxy mortar and its preparation method and an epoxy mortar with good adhesion respectively. The above technologies can achieve high-strength and fast-curing at room temperature, but when the temperature is lower than Below ten degrees, the epoxy mortar provided by the above technology will cure slowly, cannot achieve high strength and fast solidification, and cannot quickly repair the structure well

Abstract

The invention discloses epoxy mortar prepared by mixing an A component, a B component and a C component with the mass ratio of 3:1:(6-16), wherein the A component includes 60-80 parts by weight of bisphenol A epoxy resin, 20-30 parts by weight of bisphenol F epoxy resin, 10-30 parts by weight of 711 low temperature epoxy resin and 5 parts by weight of a toughening agent; the B component includes 60-80 parts by weight of a phenolic aldehyde amine curing agent and 10-20 parts by weight of a fatty amine curing agent; the C component includes 100 parts by weight of quartz sand and 20-40 parts by weight of fly ash. An experiment is carried out in the environment of the temperature of 0 DEG C-10 DEG C, and the epoxy mortar can be hardened in 12 hours; the epoxy mortar can be still hardened in three days in the low-temperature environment of the temperature of -10 DEG C-0 DEG C, and the strength is reflected. A low-viscosity system is selected, a large number of coarse aggregates can be added, the test strength is high and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an epoxy mortar for rapid repair in a low-temperature environment and a preparation method thereof. Background technique [0002] Epoxy mortar is a high-strength, chemical-resistant engineering material that uses epoxy resin curing agent as the gel material and quartz sand and other aggregates. Compared with cement mortar, epoxy mortar has early strength and high strength. , good bonding effect with the base material, simple operation and so on. ZL 201210311463.0 and ZL 201510153654.2 proposed a high-strength and fast-curing epoxy mortar and its preparation method and an epoxy mortar with good adhesion respectively. The above technologies can achieve high-strength and fast-curing at room temperature, but when the temperature is lower than Below ten degrees, the epoxy mortar provided by the above technology will cure slowly, cannot achieve high strength and fast solidification, ...
