Problems solved by technology

[0003] However, the colored pavement is easy to be polluted due to the large difference in color from the surrounding color; in addition, due to the influence of external factors such as ultraviolet rays and rain, the color of the colored pavement will fade
At present, the commonly used maintenance methods in China are: to spray paint with the same color for repair, but if you use solvent-based paint to spray, the cost is high and it will seriously pollute the environment; if you use water-based paint to spray, the bonding strength is small and it is easy to contact with water. The paint film comes off; the existing restoration agent has higher requirements on the pH of the pavement to be repaired, and cannot meet the restoration of the acidic pavement and the alkaline pavement; therefore, there is an urgent need for a high viscosity, low cost, pollution-free, A non-ionic colored pavement color repair agent and its preparation process that can meet the repair of acidic pavement and alkaline pavement, have a long service life, and can maintain the same color and binder properties as the colored pavement

Abstract

The invention discloses a nonionic water-based color restoration agent for a colored pavement and a preparation process thereof. The preparation process of the nonionic water-based color restoration agent comprises the following steps of: mixing materials A and B in a weight ratio of (30-40%): (60-70%), and cutting by a colloid mill, wherein the material A is prepared by mixing the following components in parts by weight: 50-55 parts of furfural extract oil, 3-4 part of styrene-butadiene-styrene block copolymer, 37-45 parts of petroleum resin and 1 part of dioctyl phthalate, and the material B is prepared by mixing the following components in parts by weight: 2-3 parts of stearyl alcohol polyoxyethylene ether, 0.7 part of inorganic pigment and 96.3-97.3 part of water. The nonionic water-based color restoration agent has the advantages of high viscosity, low production cost, no pollution and capability of restoring an acidic pavement and an alkaline pavement at the same time and long service life, and is identical with the color of the colored pavement and the property of a binder; and moreover, the technical indexes of the nonionic water-based color restoration agent reach requirements in specification of regeneration technology of highway bituminous pavement (JTGF41-2008).

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a non-ionic water-based colored pavement color restoration which can be used in the process of road engineering treatment of fading, pollution and other diseases on the colored pavement and can maintain the same color and binder properties as the colored pavement agent and its preparation process. Background technique [0002] At present, colored asphalt has entered the stage of experimentation and promotion in my country, and many cities have tried to use colored asphalt concrete to pave urban roads, such as Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. There are many colors of colored asphalt mixture, but generally red, yellow, green and blue are the main colors. [0003] However, the colored pavement is easily polluted due to its large color difference from the surroundings; in addition, due to the influence of external factors such as ultrav...
