Advantages of waterborne epoxy flooring
Waterborne epoxy resin with its outstanding performance advantages, the preparation of waterborne epoxy resin coatings also has excellent performance, resulting in water of product family is becoming more and more important, experts believe that the waterborne epoxy resin in the environmental protection today, the prospects are very broad.
Waterborne epoxy resin is a stable dispersion system, which is dispersed in the form of particles or droplets in the dispersed medium with water as the continuous phase. Due to the linear structure of thermosetting resin is epoxy resin, so before construction must be waterborne epoxy curing agent is added, in room temperature environment occur chemical cross-linking reaction, after the curing of the epoxy resin changed originally soluble can properties of molten and become insoluble and infusible spatial reticulated structures, shows excellent performance. Waterborne epoxy resin coatings have many merits like solvent type epoxy resin coating, is a strong ability to adapt to many substrates with high adhesion, coating after curing, corrosion resistance and chemical resistance and excellent coating shrinkage, high hardness, good abrasion resistance, excellent electrical insulation properties; two is a good environmental performance, but also has no organic solvent or volatile organic compounds content is low, does not cause air pollution, and thus meet the requirements of environmental protection; the three is the real water, with water as the dispersion medium, low price, no smell, no burning, storage, transportation and safety in the process of using it is greatly improved; four is easy in operation, construction and operation performance of waterborne epoxy resin coatings, construction tools available direct water cleaning, can be at room temperature and humid environment. The curing time is reasonable, and the crosslinking density is guaranteed. This is the usual water borne acrylic coatings and waterborne polyurethane coatings can not be compared.
Epoxy resin coatings with different properties can be prepared by reasonable selection of epoxy resin, curing agent, and various modifiers and additives. The performance characteristics of waterborne epoxy resin coatings have a wider application prospect compared with solvent based or solvent free epoxy coatings. China Epoxy Resin Industry Association experts said that the current application of waterborne epoxy resin coating mainly includes following several aspects: one is the industrial coating, can be used as a high performance environmental friendly floor coating to replace solvent type epoxy resin coating, can also be used as components of the polymer cement mortar is made of high performance polymer mortar flooring material is three; the wooden floor paint, varnish for wood floors can be matched, replace the solvent based polyurethane crystal floor paint is widely used on the market at present, with color paint can replace the solvent type epoxy resin and polyurethane paint for magnetic, kitchen, furniture and equipment; four is the construction of anti permeability, with mechanical properties of waterborne epoxy resin coatings excellent and good compatibility with cement, preparation of high strength concrete, the waterborne epoxy resin coatings as auxiliary components are added to Impermeability of concrete or cement mortar and concrete can be improved; the fifth is the construction of waterproof bonding, using epoxy resin on the cement material and many organic materials with good adhesive properties and epoxy resin itself excellent mechanical properties and resistance to chemical properties as sticky concrete bonding agent and waterproof plugging materials, anti-corrosion treatment and other purposes, using epoxy resin excellent resistance corrosion as corrosion protective coatings used for steel and ship anti-corrosion primer, and other general emulsions such as polyacrylic emulsion, waterborne polyurethane with using synergistic effect to coating with different properties.
