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 preparation method of high-strength corrosion-resistant industrial filter cloth, belongs to the field of industrial filter cloth, and aims to solve the problems that the conventional industrial filter cloth is relatively low in strength, the surface of the conventional industrial filter cloth is damaged after being used for a long time, and the conventional industrial filter cloth is in contact with a high-corrosion solvent during filtering, so that the surface is corroded, and the filtering effect is reduced. In the process of preparing the industrial filter cloth, reinforcing particles and corrosion-resistant particles are prepared, the reinforcing particles contain benzoxazine structures, the benzoxazine structures have good wear resistance, an intermediate 6 is grafted on graphene, so that the toughness of the reinforcing particles is improved, the molecular structure of the reinforcing particles is in a net shape through polymerization, and the strength is greatly enhanced; the surfaces of the corrosion-resistant particles are wrapped with epoxy resin structures, the good corrosion-resistant effect is achieved; meanwhile, due to a large number of naphthalene biphenyl structures, the toughness of polyester fibers is further improved, and the reinforcing particles and the corrosion-resistant particles can be evenly dispersed in the polyester fibers.

Description

Technical field [0001] The present invention relates to the field of industrial filter cloth, and more particularly to a method of preparing high-strength corrosion-resistant industrial filter cloth. Background technique [0002] The development of industrial production has greatly improved people's material life, but the waste gas wastewater pollution environment produced by industrial production has become an urgent problem solved. In order to better develop production and improve the environment, there have been many efforts and practices in the treatment of environmental pollution in the past few years, and have achieved great results. [0003] The entire filtration market is rapidly developing, and the application of fibrous filtration materials in pollution control and environmental governance are more and more wide. The filter cloth material is "heart" of the filter separation equipment, which is an important part of the decision separation effect, plays a very important r...
