Embodiment Construction

[0037] The present invention explains in detail the specific process of preparing the high silica composite felt through five specific examples.

[0038] In each embodiment, a high-silica composite felt was prepared by using a high-silica glass fiber mat continuous compound unit. The technical scheme of the high-silica glass fiber mat continuous composite unit is disclosed in the patent application document with application number 201420757783.3.

[0039] The high-silica glass fiber mat continuous composite unit includes an uncoiling mechanism, a gluing mechanism, a drying furnace and a winding mechanism, and is arranged in sequence according to the sequence of the uncoiling mechanism, the gluing mechanism, the drying furnace and the winding mechanism, and The centerline of the frame width direction of the uncoiling mechanism, the centerline of the frame width direction of the gluing mechanism, the centerline of the frame width direction of the gluing mechanism of the drying f...

Abstract

The invention discloses a preparation method of high-silicon-oxygen composite felt. High-silicon-oxygen glass fiber felt cloth continuous composite machine set is used for enabling high-silicon-oxygen felt and a piece of high-silicon-oxygen cloth to run synchronously, and through uncoiling of the felt and the cloth, and cloth rectification, cloth single-side gluing, felt and cloth adhering and squeezing, drying, edge cutting and winding, the required high-silicon-oxygen composite felt is formed. The high-silicon-oxygen cloth with better tensile strength is adopted for manufacturing the high-silicon-oxygen needle felt, and different properties of the composite felt are mutually complementary in advantages, so that the original high-temperature resistance of the high-silicon-oxygen needle felt is kept, and the mechanical property and the comprehensive performance of the high-silicon-oxygen composite felt can be improved; the high-silicon-oxygen composite felt can be widely applied to special occasions, where high-temperature resistance and relatively good tensile strength are required, in fire fighting, military, industry and the like, and the application field and the application range of the high-silicon-oxygen composite felt are broadened.

Description

technical field [0001] The invention relates to the field of manufacturing composite felt materials, in particular to a method for high-silica composite felt materials. Background technique [0002] In the invention with the application number 201020659434.X, a glass fiber and aramid fiber composite filter needle felt is disclosed, which is a double-sided needle punched aramid fiber on the glass fiber base cloth, which improves the chemical corrosion resistance of the filter material However, the hydrolysis resistance of aramid fiber is slightly poor, and the temperature resistance is only 220°C. [0003] In the invention with the application number 200410024542.9, a method for manufacturing a composite fiber needle felt is disclosed, which is a composite needle felt made of glass fiber and polypropylene fiber. The process is too simple, and the fibers are mixed unevenly. Without the base fabric layer, the structure is loose and the strength is low, and it cannot withstand ...
