水性环氧地坪树脂以其突出的性能优势，使制备得到的水性环氧树脂涂料同样具有优异的性能，从而在水性产品大家族里地位越来越重要。水性环氧地坪树脂是指环氧树脂以微粒或液滴的形式分散在以水为连续相的分散介质中而配得的稳定分散体系。由于环氧树脂是线型结构的热固性树脂，所以 施工前必须加入水性环氧固化剂，在室温环境下发生化学交联反应，环氧树脂固化后就改变了原来可溶可熔的性质而变成不溶不熔的空间网状结构，显示出优异的性 能。水性环氧树脂涂料除了具有溶剂型环氧树脂涂料的诸多优点：
Waterborne epoxy floor resin with its outstanding performance advantages, so that the preparation of waterborne epoxy resin coatings also have excellent performance, thus in the aquatic product family is becoming more and more important. Waterborne epoxy floor resin is a stable dispersing system which is prepared by dispersing epoxy resin in the form of particles or droplets in the dispersing medium with water as continuous phase. Since epoxy resin is a linear thermosetting resin, waterborne epoxy curing agent must be added before construction. Chemical crosslinking reaction occurs at room temperature. After curing, epoxy resin changes the original soluble and fusible properties and becomes insoluble and insoluble space network structure, showing excellent performance. Waterborne epoxy coatings have many advantages over solvent based epoxy coatings:
It has strong adaptability, high adhesion to many substrates, excellent corrosion resistance and chemical resistance of the cured film, small shrinkage, high hardness, good wear resistance, excellent electrical insulation and so on. 环保性能好，还具有不含有机溶剂或挥发性有机化合物含量较低，不会造成空气污染，因而满足当前环境保护的要求；
Good environmental protection performance, but also does not contain organic solvents or volatile organic compounds content is low, will not cause air pollution, thus meeting the current environmental protection requirements;
Real water-borne, water as a dispersing medium, inexpensive, odorless, non-flammable, storage, transportation and use of the process of security has greatly improved;
Good operability, water-borne epoxy resin coating construction performance is good, construction tools can be directly cleaned by water, can be cured at room temperature and humid environment, a reasonable curing time, and ensure a high crosslinking density.
This is incomparable to the usual waterborne acrylic coatings and waterborne polyurethane coatings.
The waterborne epoxy resin coatings with different properties can be prepared by selecting epoxy floor resin substrate, curing agent, various modifiers and additives reasonably. Water-borne epoxy resin coatings have more extensive application prospects than solvent-based or solvent-free epoxy resin coatings because of their many properties. Experts from China Epoxy Resin Industry Association said that the current application of waterborne epoxy resin coatings mainly includes the following aspects:
Industrial floor coating can be used as a high-performance environment-friendly floor coating instead of solvent-based epoxy resin coating, or as a polymer component mixed with cement mortar to make high-performance polymer mortar floor materials.
Wood floor coatings can be used as varnishes for wood floors, instead of solvent-based polyurethane crystal floor coatings which are widely used in the market at present. Paints can replace solvent-based epoxy resin and polyurethane enamel, used in kitchens, furniture and mechanical equipment.
The waterborne epoxy resin coatings can be used as auxiliary ingredients in concrete or cement mortar to improve the impermeability of concrete.
Building adhesive waterproofing, using epoxy resin to cement materials and many organic materials good adhesive properties, epoxy resin itself excellent mechanical properties and chemical resistance properties as concrete adhesive and waterproof plugging materials;
For anticorrosive treatment and other uses, the excellent corrosion resistance of epoxy resin is used as anticorrosive paint as anticorrosive primer for steel and ship. Synergistic effect with other general emulsion such as polyacrylic acid emulsion and waterborne polyurethane is used to obtain different properties of the coating.
