Research On Formula Optimization And Molding Experiment Of Watertight Connector

With the development of society and the constant progress of science and technology,the heat of exploration for the sea is constantly on the rise.The exploration and development of marine resources can not afford the support of equipment and the guarantee of technology.At the same time,energy is needed in the exploration of marine resources The supply and transmission of signals,the supply of energy and the transmission of signals are generally accomplished using underwater sealing cables,but the head and tail of underwater sealing cables need to be connected by a submerged connector with a sealing effect so that the watertight connectors After a long development,after nearly half a century of research on watertight connectors,watertight connectors have achieved the function of water and underwater plugging.At the same time,with the continuous maturation and improvement of watertight connector technology,the current watertight connectors Depth of work can reach10,000 meters below.Watertight connectors play an important role in the exploration of marine resources and can not be replaced by other marine equipment.The advanced technology of watertight connectors has been monopolized by developed countries so far.The research on watertight connectors made in China of the results only equivalent to the level of research in the initial stage of foreign countries,due to the longer cycle of watertight connectors and the relatively high price,to a large extent restricted China's exploration of marine resources.(1)In order to domesticize the watertight connector as soon as possible,this paper mainly studies the outer insulating material neoprene 2442 of the watertight connector from the materials used for the watertight connector,and improves the physical and mechanical properties of the neoprene 2442 by optimizing the design formula Performance,and then explore the adhesive properties of neoprene 2442 with brass,improve the performance of neoprene 2442 with brass bonding to a large extent to ensure the safety of watertight connectors;Finally,the water tight connector molding Design with vulcanized mold and simulate design mold with FLUEN.By studying the influence of vulcanization system on the physical and mechanical properties of neoprene 2442,the optimum vulcanization system adapting to(2)chloroprene rubber 2442 was explored.In this paper,the vulcanization system of chloroprene rubber is:zinc oxide,magnesium oxide,Common vulcanization and DM vulcanization accelerator.By exploring the different proportions of the above four materials,the best comprehensive physical and mechanical properties of neoprene are obtained.(3)The influence of reinforcing system on the physical and mechanical properties of neoprene 2442 was studied by using the neoprene 2442 formula under the best vulcanization system as the basic formula.The reinforcing systems used in this paper are carbon black N550 and White carbon black.By changing the ratio of carbon black N550 and white carbon black to explore the best ratio,and because of the design of the formula obtained for underwater environment,so taking into account the case of white carbon black water to get the best physical Mechanical properties formula.(4)Based on the best physical and mechanical properties of the formula obtained as a basic formula to study the adhesive system on the adhesion of neoprene and brass size,this paper uses chemical bonding and physical bonding compared to explore the appropriate Neoprene and brass adhesive bonding system,wherein the chemical bonding adhesive system used in the inter-a-white-cobalt bonding system,the middle of a white cobalt resorcinol donor,In this paper,the resorcinol donor SL-3022;A methylene donor,methylene donor in this paper is RA-65;white is white carbon black;cobalt salts used in this article is the Kwai Cobalt acid.The best formulation was obtained by varying the ratio of the meta-a-white-cobalt adhesive system.Since the vulcanization of the rubber compound and the bonding with the brass during the bonding of neoprene 2442 and brass Occurred,in the process of getting the best formula to consider the impact of vulcanization time on the bonding,to explore the best time for bonding;physical bonding using the open mulok 205 for bonding,by changing the ratio of open mulok and thinner To explore the best bonding ratio.The result is a compound with optimum physical and mechanical properties as well as adhesion properties.(4)To design the watertight connector injection mold and mold,through Fluent fluid simulation software to simulate the injection mold,at the same time,the molded mold is tested and the molding effect is tested,which will provide reference and lay the foundation for future research.
