Abstract

The invention discloses a modified epoxy resin concrete material and a method for preparing the same. The modified epoxy resin concrete material comprises a component A, a component B and stones, wherein the component A consists of the following components in portion by weight: 50 to 100 portions of epoxy resin, 2 to 20 portions of liquid toughening rubber, 5 to 50 portions of epoxy resin active thinner, 0.01 to 1 portion of antifoaming agent, 0.5 to 5 portions of carbon black, and 0.5 to 5 portions of ultraviolet ray absorbent; the component B comprises the following components in portion by weight: 50 to 100 portions of curing agent, 2 to 20 portions of epoxy resin inactive thinner, and 0.01 to 1 portion of the antifoaming agent; the weight percentage of the component A to the component B is 10:1-1:1; and the weight percentage of the total weight of the stones, the component A and the component B which are mixed together is 12.5:1-5:1. The modified epoxy resin concrete material has the advantages of high strength, strong deformability and good high and low temperature performance, and is unnecessary to be heated for stirring; besides, because a normal temperature curing agent is used, the latter curing speed is far higher than that of the prior epoxy asphalt concrete, and the time for traffic opening can be shortened greatly.

Description

technical field [0001] The invention relates to a building material, which is particularly suitable for a modified epoxy resin concrete material used for deck pavement of a large-span, heavy-duty traffic steel bridge and a preparation method thereof. Background technique [0002] The deck stiffness of long-span bridges is relatively small and the deformation is relatively large. The force and deformation of the steel deck pavement under the influence of traffic loads, wind loads, climate conditions, and temperature changes are complex. Flexibility, high temperature stability and fatigue durability all have higher requirements. Due to the special position and function of the bridge deck pavement, special performance requirements such as light weight, impermeability, and good bonding performance are required for the pavement layer structure. There are mainly the following types of steel bridge deck pavement used in the world: ① cast asphalt concrete; ② asphalt mastic concrete...
