Problems solved by technology

The defects of low mixing temperature and extremely tight retention time of this kind of warm-mixed epoxy asphalt make it difficult to construct, poor paving compaction, poor stability, etc. The service performance of the bridge is degraded or even seriously damaged, which seriously affects the normal use of the bridge.
The mixing temperature of TAF epoxy asphalt produced by Dayou Construction Company in Japan is about 160-170°C, and the retention time is long, which solves this technological problem better, but its compatibility is poor, toughness is poor, and the cost is too high. High, which is the key factor limiting its mass application

Abstract

The invention provides an epoxy resin curing material system for high-temperature mixed epoxy asphalt and a preparation method thereof. The preparation method comprises the following steps: firstly, mixing epoxy resin with a diluting agent to obtain a resin ingredient; secondly, uniformly mixing a curing agent, a toughening agent and a compatibilizer to obtain a curing ingredient; and finally, uniformly mixing the resin ingredient with the curing ingredient to obtain the epoxy resin curing material system. The epoxy resin curing material system and asphalt have a long holding time at a high temperature, and the viscosity of the epoxy resin curing material system and the asphalt can be maintained to be lower than 600mPa.s in 180 minutes at 170 DEG C; quick curing can be achieved under the condition of room temperature, and a curing degree of over 90 percent can be achieved in 1-2 days after the epoxy resin curing material system and asphalt are mixed; an epoxy asphalt material prepared by the epoxy resin curing material system has very high strength, and a casting body of the epoxy asphalt material at 23 DEG C has tensile strength of over 3MPa and elongation at break of over 300 percent, and has good toughness; and the concrete of the epoxy asphalt material has Marshall strength of over 70kN, and has high strength.

Description

technical field [0001] The invention belongs to the field of asphalt materials, and in particular relates to an epoxy resin curing material system for high-temperature mixed epoxy asphalt and a preparation method thereof. Background technique [0002] Epoxy asphalt has excellent high temperature stability, low temperature crack resistance, super fatigue resistance and excellent durability, and is widely used in steel bridge deck pavement, airport runway pavement, tunnel pavement pavement, etc. High traffic pavement. In 2001, epoxy asphalt was first applied on the Second Yangtze River Bridge in Nanjing, my country, and it still shows excellent application effect more than ten years later. But at present, the epoxy asphalt used in our country is mainly imported from American ChemCoSystem Company and Japan Dayou Construction Company, which is not only expensive (about 10 to 20 times that of ordinary asphalt), but also has a single product variety, which cannot be adjusted acco...
