Colored-slurry sealing layer and preparation method thereof

Abstract

The invention discloses a colored-slurry sealing layer. The colored-slurry sealing layer is characterized by containing the following components in parts by weight: 100 parts of solid powder, 16-24 parts of resin emulsion and 5-15 parts of water, wherein the solid powder contains the following components in percent by weight: 8% of white superfine calcined kaolin, 64% of white-corundum non-slip aggregate, 13% of metakaolin, 8% of sodium silicate, 4.5% of weather-resistant type pigment and 1.5% of p-toluenesulfonic acid as a curing agent; the resin emulsion contains the following components inpercent by weight: 95% of silicone acrylic emulsion and 5% of fluorocarbon resin emulsion. The colored-slurry sealing layer disclosed by the invention has the advantages that the technical scheme hashigher early strength and flexural compression ratio: the compressive strength after 3 days is more than 15MPa; the flexural strength after 3 days is more than 5MPa; under the normal-temperature drying condition, the adhesion force to asphalt pavements and cement-concrete pavements is good: the adhesion force of the asphalt pavements after a 3-day age is more than 0.6MPa; the adhesion force of theasphalt pavements after a 28-day age is more than 0.9MPa.

Description

technical field [0001] The invention relates to a color paste sealing layer, in particular to a color paste sealing layer and a preparation method thereof. Background technique [0002] With the rapid and rapid development of my country's economy, society and transportation, people have put forward higher requirements for road landscape, identification and warning functions while requiring roads to have basic accessibility functions. As the carrier of road landscape or traffic function, colored pavement is more and more widely used. At present, the main types of colored pavement include colored asphalt pavement and resin-bonded colored aggregate pavement. Years of application practice have shown that it is difficult to find stones that are hard, wear-resistant, excellent in adhesion, and similar in color to the pavement for colored asphalt pavements. Difference. Resin-bonded colored aggregate pavement uses colored ceramic particles as anti-slip aggregate, and oily binders...

Problems solved by technology

Years of application practice have shown that it is difficult to find stones that are hard, wear-resistant, excellent in adhesion, and similar in color to the pavement for colored asphalt pavements. Difference

Resin-bonded colored aggregate pavement uses colored ceramic particles as anti-slip aggregate, and oily binders such as polyurethane resin, acrylic resin, and epoxy resin can be used to adhere colored ceramic particles to the road surface by exerting the adhesive properties of resin materials , to form a colored pavement, in order to meet the durability requirements, the resin adhesive, colored ceramic aggregate and other materials used in this kind of pavement are expensive, and the cost remains high. After the surface layer, it is very easy to cause damage
