Inorganic fireproof roller shutter fabric and production method thereof

Abstract

The invention relates to an inorganic fireproof rolling curtain fabric, which is made of aluminum silicate yarn and stainless steel wire through parallel twisting, warping, sizing, threading and weaving. The inorganic fireproof rolling fabric of the present invention can be spun smoothly without adding organic fibers, which effectively improves the current situation of low fire resistance temperature of the fireproof rolling fabric caused by the addition of organic fibers in the prior art. And without the auxiliary effect of fire-resistant coating, the fire-resistant time can reach 180min, and the fire-resistant temperature exceeds 1100°C. The structure is simple, and it can be woven smoothly by using common looms. The inorganic fireproof roller blind fabric of the present invention can be used as an inorganic super fireproof roller blind base cloth, can play good fireproof and heat insulation functions without the auxiliary function of a water curtain, and is convenient to use. Inorganic fireproof rolling fabric adopts the production method of aluminum silicate yarn and stainless steel wire twisting together, which improves the dimensional stability of the fabric and will not cause deformation of the fabric surface due to multiple windings.

Description

technical field [0001] The invention relates to an inorganic fireproof rolling curtain fabric and a production method thereof, in particular to an aluminum silicate / stainless steel wire woven fabric and a production method thereof. Background technique [0002] At present, some refractory fiber cloths that can be used for the curtain surface of fireproof roller shutters at home and abroad mainly include the following types: asbestos cloth, ordinary glass fiber cloth, alkali-free expanded glass fiber cloth, pre-oxidized fiber cloth, heat radiation cloth, high silicon Oxygen cloth, aluminum silicate cloth / glass fiber reinforced type, aluminum silicate cloth / stainless steel wire reinforced type, aluminum silicate fiber felt, carbon fiber cloth, etc. These materials have their own advantages and disadvantages in terms of fire resistance and price. Among them, although the price of asbestos cloth is relatively cheap, its safe use temperature is low (<500°C), and its performanc...

AI Technical Summary

Problems solved by technology

Aluminum silicate fiber felt (blanket) is a non-woven fabric formed by needle-punching method, which maintains various advantages of aluminum silicate fiber, excellent fire resistance, and low price, but due to the use of needle-punched non-woven fabric , the strength is poor, and the high temperature strength is almost zero. Because the fire shutter has high requirements for the strength of the base fabric of the curtain surface, the aluminum silicate fiber felt (blanket) is generally seldom used as the curtain base fabric of the fire shutter, and is usually used as a fireproof curtain. Filling material for roller blinds, which plays the role of heat insulation and smoke resistance; carbon fiber cloth has excellent fire resistance, the safe use temperature can reach 1400 ℃, and the maximum use temperature is 1500 ℃, but its flame resistance time is extremely short, and the weaving process is difficult and the price is high. Also not suitable for use as a curtain base fabric for fire shutters

Aluminum silicate cloth / glass fiber reinforced type is to add a certain amount of glass fiber to improve the weaving performance of aluminum silicate fiber during spinning. This kind of cloth has excellent fire resistance, certain heat conduction resistance, heat radiation resistance, Heat convection resistance, wrinkle resistance and wear resistance, but because of the addition of glass fiber during spinning, when the temperature is higher than 500 ° C, the glass fiber begins to melt, and the strength of the cloth surface decreases. When the temperature exceeds 1000 ° C, the strength A sharp drop, when the strength of the cloth surface is less than the gravity of the cloth itself, the cloth surface will be broken, resulting in the failure of the fireproof shutter surface, and affecting its fire resistance time limit index
