Embodiment Construction

[0021] The invention is described in detail below by the examples

[0022] (1) Weigh raw materials according to the following ratio

[0023] Component A: bisphenol A epoxy resin E51 5 parts

[0024] Propylene oxide butyl ether 0.5 parts

[0025] Carbon black 2 parts

[0026] B component: polyamide curing agent 2.5 parts

[0027] Stone material and dosage: total 90 parts of basalt stone material and mineral powder with a particle size of 0-16mm

[0028] (2) Preparation method

[0029] 1. Add bisphenol A epoxy resin, propylene oxide butyl ether, and carbon black into the mixing pot, and stir thoroughly for 3 minutes to obtain component A;

Abstract

The invention relates to an epoxy resin concrete material and a microwave-coagulation preparation method thereof and comprises the composition of raw materials, the mix proportion, the preparation method, the mechanics performance testing and the like of the epoxy resin concrete material. The epoxy resin concrete material can be coagulated in a few minutes under the condition of microwave and has the advantages of even coagulation, high strength of condensate, good interface cohesiveness and excellent road performance, thus the concrete material can be used for rapid mending of concrete road surface.

Description

technical field [0001] The invention relates to an epoxy resin concrete material and a microwave curing preparation method thereof, which can be used as a rapid pavement repair material. Background technique [0002] Pavement rapid repair materials mainly include inorganic, organic and inorganic-organic composite materials. Traditional inorganic repair materials such as ordinary Portland cement concrete materials have some disadvantages, such as large shrinkage, low strength, weak bonding between new and old interfaces, and long repair and maintenance time. At present, some new inorganic repair materials have been developed at home and abroad, such as rapid hardening sulfoaluminate cement, geopolymer cement, phosphate cement, etc. A new type of alkali-activated gelling material, which has the characteristics of early strength and fast hardening, is one of the materials that were very active in international research earlier. Organic repair materials such as epoxy resin, po...
