Problems solved by technology

Although engineering plastics such as polycyclic olefin materials have the functions of insulation, protection, and water isolation, they are used in environments that are in contact with seawater and salt lake water. Since seawater and salt lake water contain various components, especially acid and alkali components, they will be severely corroded. The appearance of marine engineering products affects marine safety operations
In addition, the adhesive corrosion of marine microorganisms to materials is also a major challenge

Abstract

The invention relates to a marine microorganism adhesion-resistant olefin composite material and a preparation method thereof. The preparation method comprises the following steps: (1) weighing a copolymerized olefin material, an inorganic nano component and an olefin monomer with a cyclopentadiene structure, performing blending, and carrying out ultrasonic dispersion treatment to obtain a blend;and (2) adding the blend obtained in the step (1) and a catalyst into a reactor, mixing the substances uniformly, injecting the mxiture into a mold, and conducting polymerizing, curing and molding toobtain a target product. Compared with the prior art, the prepared olefin composite material has excellent mechanical properties like good wear resistance, high strength, high toughness and the like,and more importantly, adhesion of marine microorganisms can be effectively inhibited, and the olefin composite material has excellent marine corrosion resistance and is beneficial to application of the composite material in the field of ocean engineering.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and relates to an olefin composite material resistant to the adhesion of marine microorganisms and a preparation method thereof. Background technique [0002] With the development and utilization of marine resources, marine engineering materials are faced with problems such as huge wear and microbial corrosion, which will seriously restrict the development of major marine engineering technologies and equipment, and the failure of microbial corrosion will seriously affect marine engineering and equipment. Reliability and life, anti-corrosion and wear-resistant technology of materials have become urgent problems to be solved in the field of marine engineering in my country. For example, valves, ship diaphragms, etc., as key material components in direct contact with seawater, are in seawater for a long time and are subject to severe marine microbial corrosion and related wear. ...
