China Coatings Online News Information
by glue powder, asphalt, emulsifying agents and water at a certain temperature for high-speed stirring emulsification, can be made into water-milk waterproof coating. This waterproof coating can be constructed using mechanical spraying process, not only high construction efficiency, but also uniform coating, and increase the adhesion of coating and substation materials, its use is safe and reliable, low cost, and deformation at high temperature is small, low temperature still has a certain degree of flexibility.resin powder asphalt and solvent mixture can also be made into solvent-based waterproof coating. This waterproof coating for thick waterproof coating, because of its solid content, so less brushing, you can achieve the thickness required for construction, and save a lot of thinners, easy preparation, easy construction, low price.The waterproof coating preparation process is to melt the asphalt dehydrated, remove impurities, you can slowly add glue powder, side by side stirring, and continue to heat up, after processing a period of time. If fine powder is used, the heating temperature is 180-200 degrees, the time is about one hour. If the use of crusher crushing powder, because of the particle size, so the temperature should be 240 degrees, the time of about two hours, and finally form a uniform paste, and can pull out a uniform fine wire, and then cool down to about 100 degrees cooling, add a certain amount of gasoline to dilute, stirring evenly is waterproof paint. This coating has good heat resistance, crack resistance, low gentleness and impermeability, its processing is simple, easy to construct, abundant sources of raw materials, low price and save thinners, etc. , a wide range of applications.
