Problems solved by technology

At present, some low-end fire curtains and fire blankets are made of alkali-free glass fiber cloth, which has a very short lifespan and poor heat insulation. The material becomes brittle and easily damaged when exposed to high temperature for a long time, thus endangering personal safety.
However, although the existing high-silica high-temperature-resistant cloth on the market has a high silica content, its strength is relatively low, and its production cost is high and expensive.

Embodiment 1

[0015] (1) The non-alkali glass fiber cloth purchased from the market is dewaxed first, and then dewaxed at 300°C in a continuous dewaxing furnace. The paraffin-type surface pretreatment agent contained in the fiber is completely melted away and becomes bare inorganic glass fiber.

[0016] (2) Then carry out acid leaching treatment, inject hydrochloric acid with a concentration of 1.5mol / L into the acid leaching tank, distribute the alkali-free glass fiber cloth after hot-melt treatment on a special frame in an orderly manner, and put it into the acid leaching tank. In the washing tank, use an acid-resistant pump for circulating stirring and auxiliary bubbling stirring to strengthen the ion exchange process, and heat it with steam to control the reaction temperature at 80 ° C. After 1.5 hours of treatment, take it out for washing.

[0017] (3) Washing with water First, spray the surface of the cloth to remove residual acid on the surface of the cloth layer, then soak it in cle...

Embodiment 2

[0021] (1) The non-alkali glass fiber cloth purchased from the market is first dewaxed, and then dewaxed at a temperature of 380°C in a continuous dewaxing furnace. Cloth, the paraffin-type surface pretreatment agent contained in the fiber is completely melted away, and becomes bare inorganic glass fiber.

[0022] (2) Then carry out acid leaching treatment, select hydrochloric acid with a concentration of 3mol / L and inject it into the acid leaching tank, distribute the alkali-free glass fiber cloth after hot-melt treatment on a special frame in an orderly manner, and put it into the acid leaching tank. In the tank, an acid-resistant pump is used for circulating stirring and auxiliary bubbling stirring to strengthen the ion exchange process, and it is heated with steam to control the reaction temperature at 85 ° C. After 2 hours of treatment, it is taken out and washed with water.

[0023] (3) Washing treatment: first spray the surface of the cloth to remove residual acid on th...

Abstract

The invention discloses a high-temperature resistant glass fiber cloth and a fabricating technique thereof. Common alkali-free glass fiber cloth is used as raw material and is subject to dewaxing treatment in a continuous type dewaxing furnace, after the treatment, paraffin wax pretreatment agent on the surface of the alkali-free glass fiber cloth is completely wiped out, and the glass fiber is exposed; the alkali-free glass fiber cloth after the dewaxing treatment is put into a tank, an acid-proof pump is used for circular stirring and assistant gas sparging stirring so as to reinforce ion exchange process; afterwards, spraying treatment is carried out on the cloth surface to wipe out the surface residual acid, then the cloth is soaked in clear water to be washed by flowing water; after water washing, primary drying is carried out in the continuous type kiln; after the primary drying, the surface of the alkali-free glass fiber cloth is subject to gum dipping, mudjacking, drying and coiling to obtain the finished product high-temperature resistant cloth.

Description

technical field [0001] The invention relates to a high-temperature-resistant cloth and a manufacturing method thereof, in particular to a high-temperature-resistant glass fiber cloth and a manufacturing method thereof, belonging to the field of special new materials. Background technique [0002] With the continuous development of the economy, the demand for fire curtains and fire blankets in industries such as industrial smelting and welding has surged. At present, some low-end fire curtains and fire blankets are made of alkali-free glass fiber cloth, which has a very short lifespan and poor heat insulation. When exposed to high temperature for a long time, the material becomes brittle and easily damaged, thus endangering personal safety. However, although the existing high-silica high-temperature-resistant cloth on the market has a high silica content, its strength is relatively low, and its production cost is high and expensive. Contents of the invention [0003] The p...
