Abstract

The invention discloses a glass fiber coated filter cloth and a manufacturing method thereof. The glass fiber coated filter cloth comprises a polytetrafluoroethylene film layer, a glass fiber layer, glass fiber warps and glass fiber wefts, the glass fiber layer is connected below the polytetrafluoroethylene film layer, and the glass fiber layer is formed by weaving the glass fiber warps and the glass fiber wefts. The thickness of the glass fiber layer is greater than that of the polytetrafluoroethylene film layer. The method comprises the following steps: preparing glass fibers, preparing expanded polytetrafluoroethylene, and laminating and packaging expanded filter cloth. A plurality of weaving processes, namely a double twill process, a 1 / 3 twill process and a weft double process are set. According to the glass fiber coated filter cloth, the glass fiber warps and the glass fiber wefts in the glass fiber base cloth are combined in various modes, so that the final glass fiber coated filter cloth has different physical properties, has good working performance in different fields, can exert the maximum advantages in different fields, and improves the use effect of the glass fiber coated filter cloth.

Description

technical field

[0001] The invention relates to the technical field of glass fiber coating, in particular to a glass fiber coating filter cloth and a manufacturing method thereof. Background technique

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulation materials and thermal insulation materials, circuit ...
