Problems solved by technology

[0005] Due to the aging phenomenon of asphalt materials, the performance of most modified asphalt and mixtures will decay over time, which will still reduce the high temperature stability of asphalt pavement
This kind of problem can only be solved by repairing the existing road surface, which not only causes economic waste but also has a great impact on ensuring smooth traffic
In addition, some asphalt pavements after adding modifiers cannot achieve pavement regeneration is also a problem that plagues road workers

example 1

[0040] The coating formula of the present invention is by following mass ratio:

[0041] Mixed resin system 65%

[0042] Composite pigments and fillers 30%

[0043] Dispersant 1%

[0044] Anti-settling agent 2%

[0045] Initiator 2%

example 2

[0047] The coating formula of the present invention is by following mass ratio:

[0048] Mixed resin system 70%

[0049] Composite pigments and fillers 25%

[0050] Dispersant 1%

[0051] Anti-settling agent 2%

[0052] Initiator 2%

[0053] (2) Preparation process

[0054] Adjust the viscosity of the above-mentioned mixed resin system to meet the construction requirements, adjust the speed of the stirring equipment, and control its speed at 200-500r / min, then add additives such as composite pigments and fillers, anti-settling agents, and continue stirring for several minutes. The total stirring time should be controlled Within 30 minutes, add the initiator before use and stir evenly before construction.

[0055] Precautions:

[0056] 1. In order to prevent air bubbles in the coating, the blade agitation should be stopped after gradually decelerating;

[0057] 2. The rotating speed should not be too fast, which will easily damage the composite pigments and fillers, caus...

Abstract

The invention discloses a colorful selective solar heat reflective coating for an asphalt pavement. The coating comprises the following components in percentage by weight: 60-80 percent of a mixed resin system, 15-35 percent of composite pigment filler, 0.5-2 percent of dispersant, 0.2-3 percent of anti-settling agent and initiator, wherein the mass ratio of the initiator to the coating is between 0.5 and 3. The coating is characterized by rich and durable colors, high heat reflection rate, high abrasion resistance and other advantages, and can be applied to plaza, parking areas, roads and other situations, so that the pavement temperature can be reduced, and the urban road transportation environment can be promoted and an excellent urban image can be built due to rich colors.

Description

technical field [0001] The invention belongs to the technical field of materials used in road engineering, and relates to a multi-color selective solar heat reflection coating for asphalt pavement. Background technique [0002] Asphalt pavement is a pavement structure composed of asphalt material as a binder to bond mineral materials to build a surface layer and various bases and cushions. It is also called "black pavement" because of its black color. It is precisely because the road surface is black in color and the solar absorption rate is as high as 0.85-0.95, so it has a high solar heat absorption capacity. In summer, under the continuous heat radiation of the sun, the asphalt pavement absorbs a large amount of heat and accumulates it in the pavement structure, making the pavement temperature much higher than the air temperature. [0003] Most parts of my country are areas with severe high temperature in summer at the same latitude in the world, and the temperature is g...
