    如何断定着水性环氧地坪涂料成膜的本能?

    由于水性环氧地坪具有水性化、运用便当、透气性好等优点,逐渐被广泛应用到人们的生活当中去,而水性环氧地坪涂料成膜是楷模的物理化学进程,其固化成膜的是非直接感化到所构成的涂膜的各种屈从。水性环氧涂料的成膜进程既遭到水性环氧树脂乳液与水性环氧固化剂本人的物理化学成绩的感染,全盘还遭到固化进程中处境地方的影响。

    Waterborne epoxy flooring has been widely used in people's lives because of its advantages of water-borne, convenient use and good permeability. The film-forming process of waterborne epoxy flooring coating is a model of physical and chemical process, and its curing process is not directly affected to the various submissions of the film. The forming process of waterborne epoxy coatings is not only affected by the physical and chemical results of waterborne epoxy emulsion and waterborne epoxy curing agent, but also affected by the situation of curing process. 

    1、景况要素对水性环氧涂料固化成膜进程的影响水性环氧涂料的成膜进程触及到水分的挥发与景象固化交联两个底细进程,在水分的蒸发进程中,环氧树脂和水性环氧固化剂进行交联回响。当水的蒸发速度快于固化速度时,涂膜中不含水分,假如水的蒸发速度小于固化速度,涂膜外表固化太快,有有些水分没有跑出而结束在涂膜里面而影响究竟?涂膜功能。环境要素如温度、湿度等对涂膜水分的蒸发与固化反响速度都有影响,这使得涂料开工时的环境温度、相对湿度和通风等仰求的使用自在比溶剂型环氧屯锵?稳重。

    1. The influence of scene factors on the curing and film-forming process of waterborne epoxy coatings. The film-forming process of waterborne epoxy coatings involves two processes: volatilization of water and cross-linking of scene curing. During the evaporation process of water, the cross-linking reaction of epoxy resin and waterborne epoxy curing agent occurs. When the evaporation rate of water is faster than the curing rate, there is no water content in the film. If the evaporation rate of water is lower than the curing rate, the surface of the film solidifies too fast. Some water does not run out and ends in the film, which affects the function of the film. Environmental factors such as temperature and humidity have an impact on the evaporation and curing reaction speed of the film moisture, which makes the environmental temperature, relative humidity and ventilation of the paint during its start-up more comfortable than solvent-based epoxy.

    2、分散相粘度和玻璃化温度对水性环氧涂料固化成膜的影响水性环氧涂料的固化反响由水性环氧固化剂的分散进程随心所欲,分散相的粘度与玻璃化温度影响到水性环氧固化剂的分散速率,分散相的粘度越大、玻璃化温度越高,越患难于水性环氧固化剂分子的分散,是以这两个要素构成了固化剂向分散相粒子内有些散的壁垒。分散相颗粒的粘度和玻璃化与所用的环氧树脂的品种、乳化花色以及固化进程中反响实路途度有关。

    2. The influence of dispersed phase viscosity and glass transition temperature on the curing film formation of waterborne epoxy coatings The curing reaction of waterborne epoxy coatings depends on the dispersing process of waterborne epoxy curing agent. The viscosity and glass transition temperature of dispersed phase affect the dispersing rate of waterborne epoxy curing agent. The higher the viscosity and glass transition temperature of dispersed phase, the more difficult it is to disperse waterborne epoxy curing agent molecules. These two factors constitute some barriers for the solidifying agent to disperse into the dispersed phase particles. The viscosity and vitrification of dispersed phase particles are related to the type of epoxy resin used, the emulsification color and the reaction path in curing process.

    3、水性环氧固化剂与环氧树脂的相容性对水性环氧涂料固化成膜进程的影响水性环氧固化剂与环氧树脂的相容性越好,水性环氧固化剂的离别越简单,越有利于固化。环氧树脂是亲油性的,多胺类固化剂平凡亲水的,为了改良两者的相容性,寻常水性环氧固化剂都需务奉行改性,以此来发扬两者的相容性。

    3. The influence of compatibility between waterborne epoxy curing agent and epoxy resin on the curing process of waterborne epoxy coatings The better the compatibility between waterborne epoxy curing agent and epoxy resin, the simpler the separation of waterborne epoxy curing agent, the more conducive to curing. Epoxy resin is lipophilic, polyamine curing agent is ordinary hydrophilic. In order to improve their compatibility, ordinary waterborne epoxy curing agent should be modified to develop their compatibility.

    4、分散相粒径对水性环氧涂料成膜进程的影响分散相粒子的大小宣扬既影响到水性环氧树脂乳液自己的褂讪性,所有也是影响水性环氧涂膜功能的较编纂身分。分散相粒子的粒径越小,传播规模越窄,固化实施得越美满,所构成的涂膜的物理化学功能越好。

    4. The effect of dispersed particle size on the film formation process of waterborne epoxy coatings. The size of the dispersed particles promotes the compatibility of waterborne epoxy resin emulsion, and all the more compiling factors that affect the function of waterborne epoxy coating. The smaller the particle size of dispersed phase, the narrower the propagation scale, the better the curing implementation, and the better the physical and chemical functions of the film.
