A layer structure erosion resistant rubber lining

Abstract

The invention discloses a layer structure corrosion resisting rubber lining. The rubber lining comprises a rubber base layer bonded to the inner surface of a pipeline, and a surface abrasion resisting layer bonded to the rubber base layer. The thickness of the surface abrasion resisting layer is 1 / 4-1 / 2 of the thickness of the rubber base layer. Strengthening powder composed of sepiolite fluff, nano zinc powder and ethyl orthosilicate is added in the surface abrasion resisting layer, and therefore the surface abrasion resisting layer has excellent abrasion resisting performance, scouring resisting performance and corrosion resisting performance. When the strengthening powder is prepared, due to the fact that the sepiolite fluff has a very large inner surface area, the structure of one part of sepiolite fluff can be damaged under the action of ultrasonic waves, and accordingly silicon dioxide and zinc acetate generated through hydrolysis of the ethyl orthosilicate can directly enter the interior of the sepiolite fluff, the surface character of the silicon dioxide and the physical performance of the sepiolite fluff are improved, accordingly when the strengthening powder and rubber are mixed, the strengthening powder can be sufficiently combined with the rubber, and accordingly the abrasion resisting performance and the corrosion resisting performance of the rubber are greatly improved.

Description

technical field [0001] The invention belongs to the lining material used in the field of pipeline fluid transportation, in particular to a layer structure corrosion-resistant rubber lining. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. During the transportation process, the fluid in the pipeline will cause scour and wear to the inner wall of the pipeline, which will cause problems such as wear of the pipeline after a long period of use. In actual industrial production, pipes with high wear resistance are often used in special occasions, such as polymer wear-resistant pipes, rare earth alloy pipes, etc., but the existing wea...
