Description
Technical Field
The invention belongs to the technical field of new materials, and particularly relates to a preparation method and application of super-tough high-temperature mixed epoxy resin.
Background
The pavement of the high steel bridge deck as a component part of bridge engineering has very important influence on the protection of bridge structures and the smooth traffic of areas. At present, the method for selecting materials and designing structures for paving steel bridge decks based on performance tests of paving materials according to past engineering experiences is common at home and abroad. Considering the safety and comfort of driving, reducing the load of the steel bridge, ensuring that the pavement structure has good compatibility and harmony with the steel plate, keeping good and continuous interface connection with the steel bridge and the like, the pavement layer paved by the large-span steel bridge deck at home and abroad at present is mostly selected from single-layer or double-layer asphalt mixture with smaller thickness. In terms of material types, epoxy asphalt concrete, cast asphalt concrete, modified asphalt SMA and the like are widely applied.
The epoxy resin is mixed into the asphalt, mixed with aggregate and filler, and cured to obtain the epoxy asphalt concrete, which has the following advantages: the strength is high, and the toughness is good; excellent high temperature stability and low temperature crack resistance; has strong anti-fatigue and anti-chemical substance erosion capabilities. The study of Epoxy Asphalt concrete started in the 50's of the 20 th century, and Shell incorporated Epoxy resin as a modifier into petroleum Asphalt, and finally developed an Epoxy Asphalt material named Shell Epoxy Asphalt. The San Mateo-Hayward bridge is located in the United states, is the first long-span steel bridge paved by epoxy asphalt concrete in the world, and the pavement layer of the bridge keeps good use effect after being paved for the first time in 1967. Since then, the large-span steel bridges in the united states mostly adopt epoxy asphalt concrete paving materials. Japanese scholars studied epoxy asphalt concrete from the 70 s of the 20 th century, and studied mainly from the aspects of mix proportion design, elastic modulus, strength and the like of epoxy asphalt concrete. By the 90 s of the 20 th century or so, the research on epoxy asphalt concrete has been matured in japan, and the use of epoxy asphalt in actual works has gradually started in japan. Subsequently, Japanese epoxy asphalt is gradually introduced into China and applied to a plurality of large-sized steel bridgesAnd (5) paving engineering. In China, the related research of the epoxy asphalt starts a little late. Epoxy resin was only initially incorporated into the coal tar to fill the pavement cracks. The coal-tar pitch mixture mixed with epoxy asphalt was studied by Tongji university in 1992 to 1995, and a test course of 200m total was laid on Shanghai Longwu road in cooperation with municipal engineering company in Shanghai City2. On the basis of this, the Changsha transportation institute also conducted a study of epoxy asphalt mixtures in 1998, but finally failed to develop materials that could be applied on a large scale. Meanwhile, the professor Huangwei of the southeast university starts to lead the team to comprehensively research the pavement of the steel bridge deck, and finally forms a complete set of scheme and technology for paving the large-span steel bridge deck by using the pavement layer of the second bridge of Changjiang river of Nanjing as a construction opportunity. In the beginning of the century, independent research and development of epoxy asphalt concrete are carried out by partial scientific research institutions and universities in China. At present, the large-scale production and application technology of the epoxy asphalt concrete tends to be mature, and the domestic epoxy asphalt concrete can be applied to actual engineering on a large scale. In 2007, the Tianjin Fumin bridge is paved by domestic epoxy asphalt concrete for the first time, and the working state of a pavement layer is good. However, the domestic epoxy performance is not uniform, particularly the high-temperature hot-mix epoxy technology is lacked, the foreign application of patents or technical secrecy to the key technology of the epoxy asphalt is mostly carried out, the complexity and high import price of the epoxy asphalt material technology influence the application and popularization of the epoxy asphalt material and the development of the large-span steel box girder bridge deck pavement technology in China to a certain extent, and therefore, the research on the epoxy asphalt material is necessary to be carried out. On the other hand, the difference between epoxy asphalt pavement maintenance and common asphalt mixture is large, the maintenance difficulty is also large, and the traffic safety smoothness of large-span bridges is influenced due to the defects of the pavement of partial epoxy asphalt steel bridges in China. In maintenance, if imported materials are adopted, the problems of high price, complex purchase, long arrival period and the like exist, and timely maintenance research of steel bridge deck pavement is not facilitated, so that the domestic epoxy asphalt pavement maintenance material needs to be researched, and good materials and technical bases are provided for maintenance and maintenance of the large-span steel box girder bridge deck pavement in China. At the same time, need to be paired with new type of groupAnd designing and testing, evaluating and researching the interlayer performance of the composite paving structure.
