Waterborne epoxy floor paint is a kind of floor paint product which has appeared and been widely used in recent years. It uses water as solvent, especially suitable for basement, warehouse and parking area with high groundwater level or without waterproof layer. It can effectively solve the problem of foaming of common floor paint coating on wet ground. Waterborne epoxy floor paint is a multiphase system. It uses epoxy resin as disperse phase and water-soluble curing agent as continuous phase. Its curing process is controlled by diffusion. The first curing reaction should occur at the interface. The viscous composition of the surface layer of epoxy particles increases. At the same time, the curing agent gradually diffuses into the epoxy resin, which further solidifies the epoxy resin. The main factors affecting the curing of waterborne epoxy floor coatings are as follows.
水性環氧地坪漆的特性:
Characteristics of waterborne epoxy floor paint:
1、安全環保。水性環氧地坪漆以水作溶劑,氣味小、不燃,儲存、運輸和使用方便、安全,并且符合環保要求。
1. Safety and environmental protection. Waterborne epoxy floor paint uses water as solvent. It has small odor, non-flammable, convenient storage, transportation and use, and meets the requirements of environmental protection.
2、減少涂膜缺陷。普通的環氧地坪漆漆膜致密,基面潮氣蒸發后無法透過漆膜逸出,從而形成上頂的壓力,造成涂膜起泡。而由于水性地坪漆以水作溶劑,固化后的漆膜上有細微的孔隙,基層中的水汽可以透過這些孔隙逸出,排解了基面水汽蒸發產生的壓力,有效防止地坪漆涂層起泡。
2. Reduce coating defects. Ordinary epoxy floor paint film is dense, moisture vaporization on the base surface can not escape through the film, thus forming the pressure on the top, causing the film to foam. Because water-based floor paint uses water as solvent, there are fine pore on the cured film. Water vapor in the base can escape through these pore, which can relieve the pressure caused by vapor evaporation on the base and effectively prevent the floor paint from foaming.
3、使用方便。水性環氧地坪漆施工工具可以直接用水清洗,可以降低施工成本。
3. Easy to use. Water-borne epoxy floor paint construction tools can be directly cleaned with water, which can reduce construction costs.
4、使用范圍廣??稍谑覝睾统睗竦沫h境中使用,如地下室、建筑底層等地方。
4. Wide range of use. Can be used in room temperature and humid environment, such as basement, building floor and other places.
影響水性環氧地坪漆固化的因素:
Influencing factors on curing of waterborne epoxy floor paint:
水性環氧地坪漆涂料是一種多相體系,它以環氧樹脂為分散相,水溶性固化劑作為連續相,它的固化過程由擴散控制。最先發生固化反應的應該在界面上,環氧顆粒表層的黏度組建增加,同時,固化劑逐漸擴散到環氧樹脂中,進一步使環氧樹脂固化。影響水性環氧地坪涂料固化的原因主要有以下幾個方面。
Waterborne epoxy floor paint is a multiphase system. It uses epoxy resin as disperse phase and water-soluble curing agent as continuous phase. Its curing process is controlled by diffusion. The first curing reaction should occur at the interface. The viscous composition of the surface layer of epoxy particles increases. At the same time, the curing agent gradually diffuses into the epoxy resin, further curing the epoxy resin. The main factors affecting the curing of waterborne epoxy floor coatings are as follows.
1、 環氧樹脂的粒徑。一般來說,環氧樹脂的粒徑越小,固化就越接近完全。
1. The particle size of epoxy resin. Generally speaking, the smaller the particle size of epoxy resin, the closer to complete curing.
2、 環氧顆粒的黏度和玻璃化溫度。A.水性環氧體系中的分散相環氧樹脂是液態,但隨著固化反應的進行,顆粒表面的黏度會增加,甚至變為固體,然后其玻璃化溫度也會增加,是固化劑的擴散變困難。B.固化反應的進行和溶劑的揮發會使高粘度的環氧樹脂顆粒溶劑行程對固化劑擴散的阻礙作用。
2. Viscosity and glass transition temperature of epoxy particles. A. Dispersed phase epoxy resin in waterborne epoxy system is liquid, but with the curing reaction proceeding, the surface viscosity of particles will increase, or even become solid, and then the glass transition temperature will increase, which makes the diffusion of curing agent difficult. B. The curing reaction and volatilization of solvents will hinder the diffusion of curing agent by the solvent stroke of epoxy resin particles with high viscosity.
3、 環氧樹脂與固化劑的相容性。兩者的相容性越好,固化劑就越容易向環氧樹脂內擴散,有利于固化。為了提高環氧樹脂與固化劑的相容性,建議提高涂膜的耐水性,把環氧樹脂和固化劑都設計成分散體的形式。一方面對環氧樹脂進行親水集團改性,使其具有自乳化性能。另一方面,對固化劑進行改性。
3. Compatibility between epoxy resin and curing agent. The better the compatibility between the two, the easier the curing agent diffuses into epoxy resin, which is conducive to curing. In order to improve the compatibility between epoxy resin and curing agent, it is suggested to improve the water resistance of the film and to design the disperse form of epoxy resin and curing agent. On the one hand, epoxy resin was modified by hydrophilic group to make it self-emulsifying. On the other hand, the curing agent was modified.
