Electron radiation cross-linked elastomer foam for water pump sealing and preparation method thereof

Abstract

The invention belongs to the field of high polymer materials, and particularly relates to a preparation method of electron radiation cross-linked elastomer foam for water pump sealing. The preparationmethod has the advantages of simple production technique and wide raw material sources; and chlorinated polypropylene, polyvinyl ether polymer and polyvinyl acetylene resin are used as main raw materials, a foaming agent and protein colloids are used as auxiliary materials and uniformly mixed to form slurry, and pre-foaming, oil-bath foaming and dynamic sulfurization are successively conducted toobtain a high-molecular closed-cell foam material which has a smooth and flat surface, uniform and fine internal cells, low water absorption and good sound insulation, heat insulation, shock absorption performances and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to an electron radiation cross-linked elastomer foam used for water pump sealing and a preparation method thereof. Background technique [0002] Sound insulation and vibration reduction of water pumps is a non-negligible step in the urban water supply system. Most owners complain about the noise of the pump room and the noise pollution of high-rise water pumps. It is easy to spread to the outside of the machine room through solid structures such as foundations, walls, pipes, and ceilings. On-site water pump body, water pump pipes, and pipes passing through walls are the primary focus. The frequency spectrum shows that the water pump produces low-to-medium frequency vibration noise similar to that of an elevator. The sound waves are longer and can easily bypass obstacles and penetrate walls to reach the owner's home. According to the analysis, the noise of the water pump i...

Problems solved by technology

At present, in order to reduce costs, some enterprises use azodicarbonamide in large quantities. However, since the country has not set standards for the content of formamide in floor mat products, the risk of formamide in floor mats has become a regulatory blank. At present, this In order to solve the above problems, those skilled in the art urgently need to develop a method for preparing electronic radiation crosslinked elastomeric foam for water pump sealing to meet the existing technical needs and performance requirements.
