Abstract

The invention discloses a high-temperature-resistant and microwave-permeable aluminum hydroxide / polyether sulfone conveyor belt and a method for manufacturing the same. The method includes manufacturing a polyether sulfone support by an injection molding technology; uniformly dispersing aluminum hydroxide powder in N,N-dimethylacetamide and phosphoric acid mixed solution to manufacture aluminum hydroxide emulsion; coating the aluminum hydroxide emulsion on the upper surface of the polyether sulfone support and performing heat treatment on the polyether sulfone support to manufacture a plurality of conveyor belt units; connecting the aluminum hydroxide / polyether sulfone conveyor belt units with one another by a polyether sulfone hinge pin (6) to form the aluminum hydroxide / polyether sulfone conveyor belt. The high-temperature-resistant and microwave-permeable aluminum hydroxide / polyether sulfone conveyor belt and the method have the advantages that polyether sulfone is processed by an injection process, the high-temperature-resistant and microwave-permeable aluminum hydroxide / polyether sulfone conveyor belt is suitable for industrial large-scale production and is high in mechanical strength and excellent in microwave-permeable performance, and the surfaces of the conveyor belt can resist instant high temperatures ranging from 900 DEG C to 1000 DEG C, so that industrial continuous production of expanded graphite can be guaranteed, and development on offshore oil spilling emergency efficient cleaning equipment can be promoted.

Description

technical field [0001] The invention relates to the technical field of a high-temperature-resistant and microwave-permeable conveyor belt, in particular to a high-temperature-resistant, microwave-transparent aluminum hydroxide / polyethersulfone conveyor belt and a manufacturing method thereof. Background technique [0002] With the accelerated process of global economic integration and the rapid development of the marine transportation industry, the situation of oil spill pollution has become increasingly severe. In recent years, frequent offshore oil spills have occurred around the world, causing serious marine pollution and leading to a serious marine ecological crisis. Among many marine oil spill disposal technologies, adsorption technology has the advantages of high disposal efficiency and easy operation, and is the first choice for marine oil spill pollution disposal technology. Compared with activated carbon and other adsorption materials, expanded graphite, as an emerg...
