Problems solved by technology

However, due to the large difference in the properties of working materials in different industries, the use environment of filter cloth is complex, which determines the uncertainty and complexity of the selection of filter cloth materials under different conditions.
[0004] The existing industrial filter cloth itself has low strength, and the surface will be damaged after long-term use, and when filtering, it will come into contact with highly corrosive solvents, which will cause corrosion on the surface and reduce the filtering effect

Abstract

The invention discloses a method for preparing a high-strength corrosion-resistant industrial filter cloth, which belongs to the field of industrial filter cloth. The existing industrial filter cloth itself has low strength, and the surface will be damaged after long-term use, and when filtering, it will Exposure to highly corrosive solvents causes corrosion on the surface, which in turn reduces the filtering effect. In the process of preparing industrial filter cloth, the present invention prepares reinforced particles and corrosion-resistant particles. The reinforced particles contain a benzoxazine structure, and the structure has Very good wear resistance, the intermediate 6 is grafted on graphene, so that the toughness of the reinforced particles is improved, and through polymerization, the molecular structure of itself is networked, which greatly enhances its own strength, and the surface of the corrosion-resistant particles is wrapped with a ring Oxygen resin structure has a good corrosion resistance effect. At the same time, a large amount of naphthalene biphenyl structure further improves the toughness of the polyester fiber, and the reinforcing particles and corrosion-resistant particles can be evenly dispersed inside the polyester fiber.

Description

technical field [0001] The invention relates to the field of industrial filter cloths, in particular to a preparation method of high-strength corrosion-resistant industrial filter cloths. Background technique [0002] The development of industrial production has greatly improved people's material life, but the environmental pollution of waste gas and wastewater produced by industrial production has become an urgent problem to be solved. In order to better develop production while protecting and improving the environment, people have made a lot of efforts and practices in the control of environmental pollution in the past century, and achieved great results. [0003] The entire filtration market is developing rapidly, and fiber filter materials are more and more widely used in pollution control and environmental governance. Filter cloth material is the "heart" of filtration and separation equipment and an important part that determines the separation effect. It plays a very ...
