Problems solved by technology

This kind of infrared fabric has the following two deficiencies: (1) The infrared emission rate is low. Since the infrared emission performance of this fabric mainly depends on the proportion of infrared ceramic particles added to the fiber-forming polymer, generally in this type of fiber , the content of infrared ceramics is 2 to 30wt.%. If the amount is increased, there will be problems of broken filaments and poor spinnability
Nevertheless, the highest infrared emissivity of this kind of fiber fabric can only reach about 0.7; (2) the toughness is poor, due to the addition of ceramic particles in the organic fiber, resulting in discontinuity in the fiber structure, and there are a large number of fibers in the fiber. The bonding interface between the ceramic particles and the fiber matrix will cause a significant decrease in the strength and toughness of the composite material
It can be seen that the traditional infrared fiber fabric fails to achieve the goal of increasing the infrared emissivity of the fabric while taking into account the strength and toughness.

Embodiment 1

[0007] Embodiment 1: the prescription of infrared fiber cloth: infrared microglass fiber 80%, slurry 1.5%, yarn 18.5%, the oxide weight ratio in the glass raw material is: MgO: Al 2 o 3 : SiO 2 : Fe 2 o 3 :MnO:ZnO:TiO 2 :CuO:Co 2 o 3 = 9: 15: 33: 2: 1.1: 0.6: 1.0: 0.8: 1.8, the weight ratio of the slurry is: ethylene oxide amines: polyethylene oxide monomer: silanes: water = 1.0: 0.2: 0.3: 0.4 : 85.

[0008] First, the glass batch material is melted into a glass melt in the range of 1450-1550 °C, and then the melt is directly sent to a spinning machine for spinning or made into a frit for wire drawing at 1200-1400 °C, and then the filament is passed through 800- 1000℃ temperature controlled furnace.

[0009] Infrared glass-ceramic fibers are bundled into strands, spun, and then sized in a container of a size composition solution; excess solution on the glass fiber bundles is scraped off, cooled and condensed to dry naturally; the fiber bundles containing impregnated ma...

Embodiment 2

[0010] Embodiment 2: the prescription of infrared fiber cloth: infrared glass-ceramic fiber 95%, slurry 1.5%, yarn 3.5%, the oxide weight ratio in the glass raw material is: MgO: Al 2 o 3 : SiO 2 : Fe 2 o 3 :MnO:ZnO:TiO 2 :CuO:Co 2 o 3 = 6: 12: 30: 1.5: 0.6: 0.1: 0.7: 0.5: 1.5, the weight ratio of the slurry is: ethylene oxide amines: polyethylene oxide monomer: silanes: water = 2.0: 0.4: 0.5: 0.4 : 90.

[0011] To prepare infrared glass-ceramic fibers, the preparation method is the same as that of the infrared glass-ceramic fibers in Example 1. Infrared glass-ceramic fibers are bundled into strands, and several bundles of the yarns are arranged in a non-woven orientation through the whole yarn (gathering), and the non-woven orientation yarns are sized through the container of the size composition solution; the infrared crystals are scraped off The excess solution on the upper and lower surfaces of the glass fiber layer is cooled and condensed to dry naturally.

Abstract

The invention relates to an infrared micro-crystallite glass fiber cloth and a preparation method thereof. The infrared glass fiber cloth is made of infrared micro-crystallite glass fiber, sizing agent and yarn and is characterized in that the infrared micro-crystallite glass fiber accounts for 80 to 98 wt percent of the total weight, and the sizing agent takes up 1.0 to 2.5wt percent of the total weight and the yarn 0 to 20wt percent of the total weight. The technical effect of the invention is that the defects are avoided that the traditional organic polymer infrared fiber and infrared intertexture are of low strength and unsatisfactory tenacity caused by high content of ceramic powder and low infrared radiating efficiency due to low content of the ceramic.

Description

technical field [0001] The invention relates to a glass-ceramic fiber cloth and a preparation method thereof, in particular to an infrared glass-ceramic fiber cloth and a preparation method thereof. Background technique [0002] Most of the current infrared fabrics are based on fibers added with infrared ceramic particles in fiber-forming polymers, and are woven through warp and weft spinning (knitting). This infrared fabric has the following two deficiencies: (1) The infrared emission rate is low. Since the infrared emission performance of this fabric mainly depends on the proportion of infrared ceramic particles added to the fiber-forming polymer, generally in this type of fiber , the content of infrared ceramics is 2-30wt.%. If the addition is increased, the problems of broken filaments and poor spinnability will occur. Even so, the highest infrared emissivity of this kind of fiber fabric can only reach about 0.7; (2) the strength and toughness ar...
