Problems solved by technology

After the introduction of colored pavement into China, the main paving methods are colored slurry seal coat and hot mix mixture. The construction cost and its own cost are high, and the maintenance is extremely inconvenient. The color pigment on the surface is easy to wear off after a long time, and the black Stone exposure loses color effect
Cold mixing technology has developed rapidly in recent years, but due to the high cost of resin bonding materials, it is not easy to use in large areas

preparation example Construction

[0036] The preparation method of the water-based colored asphalt paint of the present invention is obtained by uniformly mixing the water-based modified asphalt with pigments (iron oxides), reinforcing fibers, fillers and sand; the water-based modified asphalt is mixed with pigments (iron oxides), The filler and the gravel are mixed in a weight ratio of 45-55:5-10:15-25:20-25; the amount of the reinforcing fiber is 4‰ of the total weight of the dry base material of the asphalt paint.

[0037] The preparation method of the water-based colored asphalt paint also includes the preparation of water-based modified asphalt, mixing 60-65 parts by weight of modified resin, 30-35 parts by weight of water, and 2-2.5 parts by weight of surfactant Made by high-speed shear colloid mill.

[0038] The preparation method of the described water-based colored asphalt paint also includes the preparation of modified resin, 40-50 parts by weight of modified c9 petroleum resin, 10-15 parts by weight...

Embodiment 1

[0047] 40 parts by weight of modified c9 petroleum resin, 10 parts by weight of polyacrylic acid methyl resin, 150 parts by weight of modified rosin resin, 20 parts by weight of aromatic hydrocarbon oil, 4 parts by weight of styrene-butadiene rubber, 1 part by weight of 300 type antioxidant and 531 parts by weight 2 parts by weight of type anti-ultraviolet agent were added together and heated at 140°C for 2 hours, then mixed uniformly through a high-speed shear mill, and 60 parts of modified resin, 30 parts of water, and 2 parts of surfactant were mixed together and passed through a high-speed shear colloid mill to prepare into water-based modified asphalt emulsion. After the material is dehydrated, it has the properties of heat resistance, weather resistance, fatigue resistance, high bond strength and ability to withstand large loads. Water-based modified asphalt and pigments (iron oxides), fillers and sandstones are mixed in a ratio of 50:6:20:24 The ratio is mixed evenly, a...

Embodiment 2

[0053] It is basically the same as Example 1, except that water-based modified asphalt is mixed with pigments (iron oxides), fillers and sand in a ratio of 45:5:15:20, and reinforced short glass fibers (with a length of 3 ~4mm), the reinforcing fiber accounts for 2‰ of the total weight of the dry base material of the asphalt paint.

Abstract

The invention provides waterborne colored asphalt coating which is low in cost, convenient to use and long in service life, a preparation method thereof and a using method thereof. The waterborne colored asphalt coating is prepared from waterborne modified asphalt, pigment, padding, aggregates and reinforced fiber, wherein the weight ratio of the waterborne modified asphalt, the pigment, the padding and the aggregates is (45 to 55) : (5 to 10) : (15 to 25) : (20 to 25); the reinforced fiber accounts for 0.2 to 0.5 percent of the total weight of a dry base material of the waterborne colored asphalt coating. The waterborne colored asphalt coating provided by the invention is a finished product material, blending is not needed again during use, an on-site in-proportion blending scheme of blending a binder with surface modified high-quality aggregates is adopted during construction, the blended materials can be directly used on the site, and complicated factors caused by on-site blending of composite materials are avoided; manual blade coating and mechanical spray coating can be adopted during construction, the using thickness is 1 to 3 mm, and the waterborne colored asphalt coating is suitable for various pavements.

Description

technical field [0001] The invention relates to an asphalt paint, its preparation method and usage, especially a water-based colored asphalt paint, its preparation method and its usage. Background technique [0002] With the development of highways and people's requirements for the travel environment, landscape art has been closely related to the lifestyle of modern people. Traditional urban road design and paving technology can no longer meet the diverse requirements of modern cities. At present, the roads in our country are generally made of black asphalt pavement and gray cement pavement. The surface has no texture and is monotonous, which cannot provide people with a good beautifying environment. Colored asphalt pavement can diversify the color of the pavement and reflect the characteristics of a city and a region, so it is quickly accepted by people. After the introduction of colored pavement into China, the main pavement methods are colored slurry seal coat and hot mi...
