The development status and trend of water-based industrial coatings

China Paint Online News Information
Water-based epoxy flooring environmental performance is obvious to all, this epoxy flooring material to water as a solvent, paint film can permeable steam, seamless dust, for mold and so on can also play a preventive role, is a comprehensive environmental protection paint, for the floor paint construction easy to use, is the floor paint manufacturer brand products.
No matter which form of hydro-epoxy resin and water-based epoxy curing agent is selected, the water-based epoxy system with practical application value is a decentralized multiphonal structure, composed of water-based epoxy resin, water-based epoxy curing agent, water and so on.
epoxy resin and curing agent are dispersed in the water phase in the form of a dispersed phase, and the cross-link curing process is an inter-permeable internal diffusion cross-linking reaction process between particles during water evaporation, so the degree of curing of water-based epoxy depends on the following four Factors:
1, compatible: the better the compatible between water-based epoxy resin and water-based epoxy curing agent, the more beneficial the curing agent particles and epoxy resin particles to each other internal diffusion, is conducive to the curing reaction;
2, hydro-hydro-oil balance value: water-based epoxy resin and water-based epoxy curing agent hydro-hydro-oil balance value is close, in the water phase to achieve consistent coexistence and stability, if the difference is large, hydro-hydrogenic groups will gradually gather in the water phase, resulting in the separation of resin phase and curing agent;
3, dispersion uniformity: in the state of multi-phase separation, only through a certain mechanical stirring action, the resin phase and curing agent can be evenly distributed in the water phase.
protect and extend the life of the board; According to statistics, 90% of the metal roofing abroad can be refurbished to achieve an extended roof life of up to 10 years. Qingdao sailing industry and trade recommendations: anti-corrosion special surface coating system after 6-8 years of original coating surface cleaning, and then sprayed twice anti-corrosion special surface coating, increase the thickness of the thin layer, you can once again extend the service life of the system, maintenance is simple and convenient.
1. General ground coating is applicable, especially for wet environment construction, such as underground parking lots, canteens and other wet places.
2. No waterproof layer on the first floor or basement, the construction of odor requirements of the site, especially applicable to the food and pharmaceutical industry.
water-based epoxy flooring paint has a very high adhesion to the substrate, cured coating film corrosion resistance, excellent chemical resistance, coating film shrinkage is small, high hardness, good wear resistance, excellent electrical insulation performance.
water as a dispersion medium to save energy, non-polluting, non-polluting, and environmental protection requirements. It is characterized by:
(1) water as a dispersion medium, do not contain toluene, xylene and other volatile organic solvents, will not cause environmental pollution, no risk of fire, to meet the current environmental requirements, of course, can also add a small amount of propylene glycol methylene ether and other air-free alcohol ether solvents to improve the water-based epoxy coating film.
(2) can be constructed and cured in a humid environment, with reasonable curing time, to ensure that the coating film has a high cross-link density.
(3) has good adhesion to most substrates, even wet substrate surfaces have good adhesion.
(4) operation performance is good, construction tools can be washed directly with water, can be reused, paint preparation and construction operation safe and convenient.
(5) cured coating film gloss is soft, good texture, and has better anti-corrosion performance and one-way breathability.
