Abstract

The invention discloses an ultrahigh-toughness epoxy resin material for hot-mixed epoxy asphalt and a preparation method of the ultrahigh-toughness epoxy resin material. The key points of the technical scheme are as follows: the ultrahigh-toughness epoxy resin material for the hot-mixed epoxy asphalt consists of a main agent A and a curing agent B, wherein the main agent A comprises bisphenol A epoxy resin, modified epoxy resin containing a flexible side chain, a reactive diluent and an epoxy terminated interface agent; the curing agent B comprises following components in parts by weight: long-chain fatty primary amine and an accelerant. The crosslinking density of an epoxy cured product is controlled by synthesizing monofunctional long-chain fatty primary amine, and finally, the operabletime of the hot-mixed epoxy asphalt material is longer than 2 hours; the compatibility problem between an asphalt phase and an epoxy phase is solved on the basis of a 'reaction induced phase splitting' technical principle; by introducing the modified epoxy resin containing the flexible side chain, the fatigue resistance of the hot-mixed epoxy asphalt material is greatly improved.

Description

technical field [0001] The invention relates to a hot-mix epoxy asphalt material, in particular to an ultra-high toughness epoxy resin material for hot-mix epoxy asphalt and a preparation method thereof. Background technique [0002] In the past 20 years, my country's long-span steel box girder bridges have entered a period of rapid construction. However, the development speed of long-span steel bridge deck pavements is far from meeting the actual needs of high temperature, rainy, and heavy loads in China. Paving materials such as epoxy asphalt have been found to have various degrees of disease after 3 to 5 years of use. In view of the strict high and low temperature performance requirements and strict bending and tensile fatigue performance requirements of steel bridge deck pavement, epoxy asphalt has always been the first choice for long-span steel bridge deck paving at home and abroad because of its unique microstructure and wide performance plasticity. material of choice...
