Plasma surface treatment can improve the hydrophilic bonding ability of steel /EPDM surface

Plasma surface modification technology is a kind of gas-solid coherent reaction system, which can effectively improve the hydrophilic, hydrophobic and biocompatibility of metal surface and greatly improve the bonding fastness of metal-metal and metal-polymer without introducing other substances and causing environmental pollution. Cleaning the metal surface is the preparation process and prerequisite for the production of various metal products. Proper cleaning methods and high quality cleaning techniques can improve the quality and performance of metal products. Among them, plasma surface treatment technology is a cleaning technology developed in recent years, and it is also one of the research hotspots in the field of atmospheric pressure plasma jet application at home and abroad. Compared with the traditional cleaning technology, plasma surface treatment has the advantages of high efficiency, environmental protection and no pollution, and compared with other cleaning technologies, plasma surface treatment has the advantages of rapid, simple, economical and controllable. The material of solid state engine combustion chamber shell is mainly steel, which is generally treated with sand blasting and solvent cleaning, followed by an insulating layer, which plays a heat preservation and heat protection role on the combustion chamber shell, prevents the high temperature and high pressure gas from reducing the strength of the shell, impairing the structural integrity of the shell, and ensures the reliable operation of the engine. EPDM rubber has the advantages of low density, good weather resistance, good aging resistance, high thermal insulation performance, corrosion resistance and so on. It is widely used in aerospace and other fields, especially for the insulation layer in the combustion chamber of solid rocket motor. EPDM as the engine of the solid insulation insulation materials, at present, the domestic research has made great progress, but the main chain of the EPDM rubber molecular structure of the saturated, itself is weak polar material, low surface energy, contact Angle, adhesive infiltration is difficult, weak boundary layer and caking difficulties, low bond strength, this limits the application of EPDM in a wider field. In the pre-treatment process, EPDM sealants are sprayed with a lubricant coating or flocking glue, replacing mechanical grinding and chemical undercoating, making them environmentally friendly. The sealing strip is pretreated with plasma surface treatment technology to make it more stable, efficient and free from wear and tear. Plasma surface treatment can improve the hydrophilicity of high steel surface, mainly by cleaning the material surface, while the hydrophilic effect is affected by the treatment power, time, distance and times, and the magnitude of which is in turn power, distance, time and times. The shear strength corresponds to the surface energy of steel. Similarly, under the same conditions, increasing the surface energy is beneficial to improving the bonding performance.
