Study On Micro-Structural Changes And Performance Of Polyacrylate In The Environmental Media Of Groundwater

In this paper, a large number of domestic and foreign access to basic literature on Polyacrylate spraying membrane to waterproof material as the research object, focused on the synthesis of Polyacrylate, applications, in the saline solution by corrosion, as well as such issues as development prospects. Three types of spray distance from the film were designed to explore the quality of spray distance on the impact of film. At the same time, further study of the three initiator concentration on the film-forming properties.Absorbent of waterproofing membranes include the ability to absorb aqueous solution (aqueous solution absorption ratio) and the absorption rate of aqueous solution (rate of speed for absorption of aqueous solution) and so on. The composition of aqueous solution is mainly divided into the absorption of distilled water, saline absorption properties. Therefore, in this article , waterproof membrane in distilled water in the immersion test is designed, and simulate the groundwater environment, the design of a waterproofing membrane at different concentrations of saline solution immersion test. According to the swelling degree of swelling curves and the determination to study the waterproof membrane solutions of different concentrations of absorption capacity and absorption rate of the solution. And observe the waterproof membrane in solution by the state of corrosion.In order to further study the effects of groundwater environment to the waterproof membrane, this article measured waterproof membrane crosslinking density after immersion, reflecting the waterproof membrane changes in the structure of cross-linking. Finally, through Fourier transform infrared spectroscopy (FTIR) , scanning electron microscopy (SEM) , waterproof membrane on the micro-structure for further characterization to determine the salt solution of waterproof membrane material crosslinked structure.
