Problems solved by technology

At present, the commonly used maintenance method in China is: use paint of the same color for repair, but if solvent-based paint is used for filling, the cost will be high and the environment will be seriously polluted; if water-based paint is used for filling, the bonding strength will be small, especially for acid stones. The potting effect of colored pavement is even worse, and it is easy to crack again when it encounters water; therefore, there is an urgent need for a fast setting, high viscosity, low cost, no pollution, long service life, and good adhesion to acidic stones. Cationic water-based colored pavement crack sealant capable of maintaining the same color and binder properties as the colored pavement and its preparation process

Abstract

The invention discloses a cation type aqueous colored pavement crack sealing material used during treatment of problems of colored pavement, such as potholes and the like, in road engineering and the preparation process of the crack sealing material. The material is prepared by shearing material A and material B with the weight ratio of 60-70%:30-40% by use of a colloid mill, wherein the material A is prepared by mixing the following components according to parts by weight: 50-55 parts of furfural extract oil and 45-50 parts of petroleum resin; the material B is prepared by mixing the following components according to parts by weight: 10-12 parts of cation CR latex, 2-3 parts of cetyl trimethyl ammonium bromide, 0.7 parts of paint, 1 part of methylcellulose and 84.3-86.3 parts of water; and the cation CR latex is prepared by emulsifying duprene rubber through cationic surfactant, and the solid content is 40%. The sealing material has the advantages that the solidification rate is high, the viscosity is high, the cost is low, the sealing material is pollution-free, the service life is long, and the sealing material has good adhesive capability to acidic stone, and simultaneously can be the same with the color of the colored pavement and the property of binder.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a kind of material which has good adhesion to acid stones and can maintain the color and binder properties of the colored road surface, which is used in the process of road engineering treatment of pits and other diseases on the colored road surface. The same cationic water-based colored pavement crack sealing material and its preparation process. Background technique [0002] With the continuous progress of society and the continuous improvement of people's living standards, people's requirements for the living environment are also gradually increasing. As a paving material with beautifying environment, colored asphalt has entered the stage of experimentation and promotion. Many cities have tried to use colored asphalt concrete. Lay roads in cities like Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. There are many colors of colored asphalt mixtu...
