Epoxy resin mortar and preparation method thereof

Abstract

The invention discloses an epoxy resin mortar comprising the following materials by weight: 90 parts of epoxy resin, 23-25 parts of curing agents, 26-28 parts of diluents, 170-190 parts of acid-resisting powder materials and 310-330 parts of aggregates. The epoxy resin mortar has appropriate curing time under high-temperature and dry climates and also has good compression strength and insulating property.

Description

technical field [0001] The invention relates to an epoxy resin mortar and a preparation method thereof, in particular to a high-insulation epoxy resin mortar used in high temperature and dry climates and a preparation method thereof. Background technique [0002] In recent years, epoxy resin mortar has been paid more and more attention as a fast-setting, high-viscosity grouting material mixed with mortar. Usually, epoxy resin mortar is prepared according to the specified ratio of epoxy resin, and the specific ratio is shown in Table 1. The unit of the data in Table 1 is parts by weight. [0003] Table 1 [0004] [0005] However, if the epoxy resin mortar is prepared according to the ratio in Table 1, the insulation value of the obtained epoxy resin mortar is not fixed, because the factors affecting the insulation value mainly include curing agent and diluent and quartz stone, The amount of powder in the ratio. Therefore, when formulating according to the standard use...

AI Technical Summary

Problems solved by technology

If the amount of curing agent is small, the linear molecules of epoxy resin cannot be completely converted into chain molecules, which will affect the compressive strength; if the amount of curing agent is too high, it will cause waste and increase the cost

[0008] In addition, the standard use ratio of epoxy resin is only suitable for use in general environments. When using the ratio in the above table to prepare epoxy resin mortar in a high temperature and dry environment, the fast drying of the curing agent will cause environmental damage. Oxygen resin mortar ingredients are solidified in a very short time, which cannot meet the operating time of normal operations, so it cannot be prepared according to the above ratio

In addition, the amount of diluent given in Table 1 is 10 to 20 parts, however, under high temperature, dry conditions, the epoxy resin cannot be diluted to have sufficient fluidity with 10 to 20 parts of diluent
