Abstract

The invention relates to a cold mixed epoxy resin material, which comprises components A and B, wherein the component A mainly consists of epoxy resin and a reactive diluent, and the component B mainly consists of a flexible curing agent, an accelerating agent, a defoamer, a thinner, a thixotropic agent and a toughening agent; and the mass ratio of component A to component B is (100:200)-(100:350), and the components are mixed with an aggregate and mineral powder to obtain a cold mixed epoxy resin mixture, wherein the mass ratio of the sum of components A and B to component C is (6:94)-(7:93). The cold mixed epoxy resin material has excellent mechanical property, temperature resistance, water resistance, solvent resistance and fatigue resistance, and in addition also has the characteristics of being environment-friendly, low-carbon, simple in construction process, and short in curing time. The cold mixed epoxy resin material is mainly applicable to patching of epoxy asphalt road surfaces, and at the same time is also applicable to paving of road surfaces of high-grade highways, tunnels, airfield runways, cement concrete bridge floors and the like. The invention discloses a preparation method of the cold mixed epoxy resin material.

Description

technical field [0001] The invention relates to a cold mixing epoxy resin material and a preparation method thereof. Background technique [0002] Petroleum asphalt is an indispensable material for the construction and maintenance of asphalt pavement, and its performance directly determines the engineering quality and structural form of the asphalt pavement. Due to the large changes in molecular weight distribution and polarity of petroleum asphalt, such composition and structural characteristics determine that it has the disadvantages of easy softening at high temperature and brittle cracking at low temperature. In order to improve the performance of asphalt, it is usually modified by adding polymers. [0003] High-performance epoxy asphalt material is a kind of polymer modified asphalt material, which uses high-performance thermosetting epoxy resin as asphalt modifier. When the epoxy resin in the asphalt reacts with the curing agent, an irreversible three-dimensional net...
