Description
Technical Field
The invention relates to a composition for adjusting the temperature of an asphalt pavement, a preparation method and application thereof, in particular to a thermosetting methacrylic resin composition for adjusting the temperature of the asphalt pavement, a preparation method and application thereof.
Background
Asphalt pavement has good flatness, driving comfort and noise reduction capability, so the asphalt pavement is widely applied to various high-grade pavements. Asphalt is a heat-absorbing material, has a wide absorption range of solar radiation light wavelength, and a large amount of heat is accumulated in an asphalt surface layer to increase the temperature of a pavement. The high temperature environment easily causes urban 'heat island effect', and seriously affects the atmospheric temperature. Therefore, it is urgently needed to develop a composition for adjusting the temperature of the asphalt pavement, which not only meets the temperature adjusting function, but also meets the actual pavement requirements.
CN102533011A discloses a composition comprising 100-150 parts by weight of fluorocarbon resin, 30-40 parts by weight of acrylic resin, 10-20 parts by weight of hollow microsphere, 40-60 parts by weight of titanium dioxide, 20-30 parts by weight of silicon dioxide and 30-40 parts by weight of auxiliary agent. The titanium dioxide is rutile titanium dioxide, and the hollow microspheres are ceramic hollow microspheres or glass microspheres. The composition takes fluorocarbon resin and acrylic resin as film forming substances, and has weak bonding property to asphalt pavements. In addition, the temperature regulating function of the combination of the cenospheres and the titanium dioxide is not good.
CN101195725A discloses a heat insulation composition for vehicle, which uses an organic resin film-forming material as a main material, and adds an infrared reflection pigment, hollow ceramic beads and silica aerogel. The hollow ceramic microspheres and the silicon dioxide aerogel are heat insulation materials, and the temperature regulation function of the hollow ceramic microspheres and the silicon dioxide aerogel applied to the asphalt pavement is poor.
