A brief description of the advantages and application of waterborne epoxy resin

With the introduction of environmental regulations and the awakening of environmental awareness, floor paint is a solvent-based paint with serious pollution, and VOC emissions are limited by domestic and foreign regulations. In order to meet the needs of environment-friendly and healthy life, the environmental road of the seven industries has been imperative. The "spring breeze" of the floor paint industry reform has also blown into the floor paint field, and the popularity of environmental protection products such as floor water paint has become the mainstream development direction of the industry.

Waterborne epoxy resin coatings made of waterborne epoxy resin with excellent performance advantages have also played an excellent performance, and are becoming more and more important in the family of waterborne products. Experts believe that waterborne epoxy resin has a very broad prospect in environmental protection today.

Advantages of waterborne epoxy coatings

1. Strong adaptability, high adhesion to many substrates, corrosion resistance of the coating after curing, small coating shrinkage, high hardness, good wear resistance, and excellent electrical insulation performance.

2, good environmental performance, no solvent or volatile organic compounds, will not cause air pollution, to meet the current environmental protection requirements.

3. With water as the dispersion medium, the safety of odorless, discontinuity, storage, transportation and use has also been greatly improved.

4. Good operability, good construction performance of water-based epoxy resin coating, construction tools can be directly cleaned with water, can be cured at room temperature and humid environment, with reasonable curing time, to ensure high cross density. This is regular waterborne acrylic coatings and waterborne polyurethane coatings can not be compared.

Reasonable selection of epoxy resin substrate, curing agent, various modifiers and additives, can produce different properties of waterborne epoxy resin coatings. Many performance characteristics of waterborne epoxy resin coatings determine a wider range of applications than solvent-based or solvent-based epoxy resin coatings.

At present, the application of waterborne epoxy resin coatings mainly includes the following aspects:

1. Industrial floor coatings can replace solvent-based epoxy resin coatings with high-performance environmental adaptability floor coatings.

2. High-performance polymer mortar pad material is made of high-performance polymer mortar mixed with cement mortar.

3. Replace the solvent-based polyurethane crystal floor coatings widely used in the market, and replace the solvent-based epoxy resin and polyurethane coatings with color coatings for kitchens, furniture, machinery and equipment, etc.

4, through the construction project seepage control, the use of water-based epoxy resin coating excellent mechanical properties and compatibility with cement, the preparation of high-strength concrete. Among them, the water-based epoxy resin coating is added to concrete or cement mortar as an auxiliary component, which can improve the impermeability of concrete.

5. Building bonding waterproof, using epoxy resin to cement materials and many organic materials have good bonding properties, epoxy resin itself has excellent mechanical properties, as a concrete adhesive and waterproof plugging material

Application Scenarios Overview of Waterborne Epoxy Resin

Waterborne epoxy resin refers to the epoxy resin in the form of dust, droplets, colloid dispersed in water stable dispersion system. The study of waterborne epoxy resin has been carried out abroad since the 1950 s, in which the epoxy resin is made into emulsion is a common research approach. Waterborne epoxy resins and curing agents are widely used as coatings.


Construction method for parking lot floor paint

The utility model relates to an epoxy floor, especially a parking lot floor paint construction. Epoxy floor is a kind of high strength, wear-resistant, beautiful floor, has the advantages of seamless, solid texture, good chemical resistance, anti-corrosion and dustproof, convenient maintenance, low maintenance cost and so on. Epoxy floor is widely used, parking lot floor often use epoxy floor.


Construction method and process of anti-skid parking lot floor paint

The invention relates to the technical field of construction, in particular to a construction method for anti-skid parking lot floor paint. In order to improve travel safety, some parking lots, toilets, steps, and ramps are equipped with non-slip floors to increase the friction between the soles or tires and the ground to prevent pedestrians from slipping or vehicles from slipping. However, the existing non-slip floor is expensive, and the comfort of pedestrians or vehicles is poor. Especially in rainy and foggy weather or water conditions, the anti-skid effect is poor. In addition, in the use environment of the garage, due to the weight and frequency of use of the car, cracks or peeling will appear on the surface of the floor paint, which destroys the overall beauty of the ground, and the later maintenance cost is high and there is safety.


Construction technology of parking lot floor paint

With the rapid development of real estate, more and more real estate enterprises began to attach importance to the planning and construction of underground garage, underground garage is no longer the original cement concrete. Because the construction of the underground garage is related to the image of the real estate enterprise, they all attach great importance to the beautiful and practical construction of the garage ground. For the parking lot floor paint is currently popular construction technology. The construction technology of floor paint for underground parking lot is introduced. The construction steps of the parking lot epoxy floor paint include basic treatment in the coating surface coating curing. So, epoxy floor paint primer, paint, paint how to construction?
