However, the commonly used industrial filter cloth has low mechanical strength, low water permeability, limited service life, and limited use under extreme conditions. The common method is to introduce high-strength resin to increase its mechanical strength, such as polytetrafluoroethylene, However, the problem brought by these resins is that on the one hand, the degree of compounding with commonly used industrial filter cloth fibers is not enough, which affects the maximum performance. A large resistance is generated, and the liquid permeability is significantly reduced. At the same time, the industrial filter cloth obtained through the above improvements is not stable in use, that is, under certain conditions, such as high strength, high temp

Abstract
The invention discloses a high-strength and high-perviousness filtering cloth material. The filtering cloth material is prepared from the following raw materials in parts by weight: polyethylene, polypropylene, polyvinylpyrrolidone, carbon nanotube, polyethylene glycol, carbon fiber, modified polyethylene acrylate, ionic modified clay, surface modifying agent, thermoplastic polyurethane, anti-ageing agent and lubricating agent. The high-strength and high-perviousness filtering cloth material disclosed by the invention has the beneficial effects that by scientific proportioning of all the materials and components, under the synergistic effect of all the components, the strength and the perviousness of the filtering cloth material are improved, so that the filtering cloth material can be applicable to the condition of rapid filtration and has a wide application range; meanwhile, by the comprehensive effect of the ionic modified clay, the surface properties of the polyethylene and the polypropylene are improved, and the filtering effect is improved; due to addition of the modified polyethylene acrylate and the thermoplastic polyurethane, the filtering effect of the filtering cloth material is further improved, and the filtering capability of the filtering cloth is improved, so that the high-strength and high-perviousness filtering cloth material has great promotion value.
Description
technical field [0001] The invention belongs to the technical field of filter cloth production, and in particular relates to a high-strength and high-permeability filter cloth material. Background technique [0002] At present, the main components used in industrial filter cloth are polypropylene, polyester, nylon, etc. Among them, polypropylene and polyester are the most commonly used. The weaving method adopts plain weave and twill weave. It has high precision, and has certain acid and alkali resistance and wear resistance. performance. However, the commonly used industrial filter cloth has low mechanical strength, low water permeability, limited service life, and limited use under extreme conditions. The common method is to introduce high-strength resin to increase its mechanical strength, such as polytetrafluoroethylene, However, the problem brought by these resins is that on the one hand, the degree of compounding with commonly used industrial filter cloth fibers is no...
