Abstract

The invention discloses monofilament filter cloth and a preparation method thereof. According to one aspect of the invention, the monofilament filter cloth provided by the invention comprises the following raw materials in parts by weight: 200 to 220 parts of resin raw material, 40 to 50 parts of basalt fiber, 5 to 15 parts of aluminum borate, 0.5 to 1.5 parts of an antioxidant, 5 to 10 parts of acompatibilizer, 2 to 3 parts of a delustering agent and 1 to 2 parts of graphite powder. According to the other aspect of the invention, the preparation method of the monofilament filter cloth, whichis provided by the invention, comprises five steps of performing monofilament preparation, raw filament preparation, weaving filter cloth, inspecting and repairing as well as performing afterfinish calendering. The used raw materials are the materials with stable physical and chemical properties, so that pollution generated in the production process is avoided and the environment pressure is reduced; furthermore, the raw materials are cheap and easily available, so that the production cost is reduced, the stability and the filtering property of the filter cloth are improved, the quality of the filter cloth is guaranteed, the strength and the wear resistance of the monofilament filter cloth are improved and the blockage condition of the filter cloth is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of filter cloth, in particular to a monofilament filter cloth and a preparation method thereof. Background technique [0002] Monofilament filter cloth is a new generation of filter material, which is widely used in foreign countries, and its price is higher than that of ordinary filter cloth. At present, there is no authoritative national and industry standard in China. In my country's coal preparation, metallurgy, chemical industry, grain and oil, environmental protection and other industries for solid-liquid separation of suspensions, most of them use multifilament woven filter cloth and non-woven needle felt for separation. However, internationally, monofilament filter cloth has been used for solid-liquid separation since the 1990s, and the work efficiency has been significantly improved. [0003] There are some defects in the monofilament filter cloth currently used. The manufacturing process of the fi...
