Zhongshida develops water-like epoxy emulsifying agents

China Coatings Online News Information: China Stone University develops water-based epoxy coating emulsifying agents. China Petroleum University (East China) developed a water-based epoxy coating in the ionized epoxy resin special emulsion agent, the main feature of the product is no organic solvent volatilization, no odor, environmental protection products, suitable for all types of industrial plants, office flooring, can be used in room temperature and humid environment, make up for the solvent-based epoxy floor coating water-sensitive weaknesses. The process steps of the new product are as follows: adding the appropriate amount of solvent to the bisphenol A epoxy resin, mixing at room temperature, heating up and slowly adding polyethylene glycol and catalyst, insulation reaction, continuing to add ddiethanolamine, after insulation reaction, drip-added bromine ethane into salt, decompression distillation to remove the amount of bromine ethane, adjusted to appropriate p with acetic acid H, that is, high-performance seasonal ammonium salt ion emulsion, the epoxy resin and emulsion mixed, stirred evenly, and slowly added to the ionized water, up to the opposite point of turn to continue to add water, to obtain a water-based epoxy resin emulsion, epoxy resin emulsion and the appropriate amount of curing agent mixed, stirred evenly, coated film, curing at room temperature.the middle and late 2000s, many clean workshop floors appeared in Europe and the United States, using a whole polymer surface layer, called epoxy flooring paint, the main components of epoxy resin and curing agent. Epoxy flooring coatings from the beginning for functional flooring: such as anti-corrosion, wear-resistant, non-slip, development to a common general industrial floor; On the basis of the wide application of industrial flooring, with the continuous improvement of people's living standards, it has been popularized and applied in home decoration. Epoxy industrial flooring has become one of the fastest growing industries in China, attracting people's attention. Water-based epoxy floor coatings use water as a dispersion medium to save energy, non-polluting, character and environmental protection requirements.Its characteristics include: water as a dispersion medium, do not contain toluene, xylene and other volatile organic solvents, will not cause environmental pollution, no fire hazards, meet the current environmental requirements, of course, can also add a small amount of air-free alcohol ether solvents such as propylene glycol methanol to improve the filming of water-based epoxy coatings; Substrate has good adhesion, even if the wet substrate surface also has good bonding, good operating performance, construction tools can be washed directly with water, can be reused, paint preparation and construction operation safe and convenient;
