Problems solved by technology

However, the asphalt pavement absorbs most of the visible light and the infrared part of the invisible light in the sunlight, causing the temperature of the pavement to rise, and the pavement continuously releases heat to heat the surrounding atmosphere, thereby exacerbating the urban heat island effect; at the same time, the high-temperature asphalt pavement also releases a large amount of The asphalt volatiles make the living environment deteriorate sharply

Abstract

The invention relates to a heat reflection coating for bituminous pavement, solving problems of heat stability disease pavement and serious urban heat land effect caused by high heat absorptivity and high temperature of bituminous pavement in summer and providing a heat reflection coating with high heat reflectivity, sound wearing resistance and good durability for bituminous pavement. The technical scheme comprises the following steps: preparing component A with 100 parts of acrylic reactive resin, 5-30 parts of high reflecting filler, 0.2-5 parts of pigment, 0.2-5 parts of accelerators, 0.5-5 parts of plasticizers, 2-10 parts of solvents, and 0.5-5 parts of anti-settling agents; preparing component B of a firming agent; and mixing component A and component B and stirring uniformly to obtain the heat reflection coating for bituminous pavement. By applying the coating to bituminous pavement surface, the pavement temperature can be reduced by 10-20 DEG C in high-temperature summer. The invention has the advantages of wearing resistance, corrosion resistance, weather resistance, good flexibility, etc.

Description

technical field [0001] The invention relates to materials used in road engineering, in particular to a heat-reflecting coating for asphalt pavement. Background technique [0002] Asphalt pavement has the advantages of high smoothness, good comfort, and low noise. In road construction in my country, asphalt pavement is being used more and more widely. However, the asphalt pavement absorbs most of the visible light and the infrared part of the invisible light in the sunlight, causing the temperature of the pavement to rise, and the pavement continuously releases heat to heat the surrounding atmosphere, thereby exacerbating the urban heat island effect; at the same time, the high-temperature asphalt pavement also releases a large amount of The asphalt volatiles make the living environment deteriorate sharply. The problem of how to maintain the excellent characteristics of asphalt pavement while reducing its surface temperature needs to be solved urgently. The technology of co...
