The basic components of the emulsified asphalt emulsion are prepared from anionic emulsified asphalt, anionic water-based acrylate emulsion and sodium carboxymethyl cellulose. Emulsified asphalt is liquid asphalt prepared by blending an emulsifier, water and asphalt melted by heating under certain process conditions and dispersed in an emulsion as fine water-in-oil or oil-in-water particles. The emulsified asphalt can be classified into three types, i.e., anionic, cationic and nonionic types, according to the kind of emulsifier used. The emulsified asphalt is used as a base material of the glass fiber coating material and is selected according to the performance of other aqueous emulsions compounded with the emulsified asphalt. Because the aqueous acrylate emulsion in the emulsion is anionic emulsion, anionic or nonionic emulsified asphalt should be selected in the compounding of the coating emulsion.
The water-based acrylate emulsion is generally prepared by polymerizing acrylate with active crosslinking functional groups, can form a crosslinked film directly through self-crosslinking when being used for a coating film, and has the advantages of excellent weather resistance, higher hardness, less pollution, easy storage and lower cost.
The coating material is prepared by compounding aqueous latex and emulsified asphalt, the compatibility between the aqueous latex and the emulsified asphalt needs to be tested, and the stability of the compounded emulsion is influenced. Sodium carboxymethylcellulose was therefore chosen as a stabilizer. The sodium carboxymethylcellulose belongs to a high-viscosity substance, the viscosity of a water phase is increased when the sodium carboxymethylcellulose is added into the emulsion, and an interface film can be formed on the surface of the latex particles, so that the latex particles are not easy to agglomerate and settle, and the stability of the emulsion is improved.
