The utility model content
The purpose of this utility model is to provide a kind of composite performance good for the deficiency that solves above-mentioned technology, intensity, hardness high fire-retardant aluminium foil glass cloth.
In order to achieve the above object, the fire-retardant aluminium foil glass cloth that the utility model is designed mainly is made of aluminium foil, and the upper strata of aluminium foil is provided with the glass cotton, lower floor in the glass cotton is provided with the alkali-free fine cloth, and the chain marshalling that constitutes by high silica glass line of described three-decker is knitted and is combined with each other.
Wherein:
Described aluminium foil is thickness 0.1mm, 270g/m
2Aluminium foil;
Described glass cotton is thickness 10mm, 1400g/m
2The glass cotton;
The alkali-free fine cloth is thickness 0.1mm, 200g/m
2The alkali-free fine cloth;
Described high silica glass line is three bursts of twisting, and high temperature resistant 580 ℃, fusing point is 1200 ℃ a high silica glass line.
The resulting fire-retardant aluminium foil glass cloth of the utility model utilizes high silica glass line that glass cotton and the alkali-free fine cloth three layered sutures volume of aluminium-foil paper, structural joint pine are composited, and has realized once spreading the layer multi-layer constructed products, has guaranteed to fit tightly between layer and the layer.The high silica glass line of selecting for use can not cut because of the hard of aluminum foil metal in the process of making, can also bear scorching of the high temperature that is up to more than 1000 degree, and the high silica glass line of three bursts of twisting can not only guarantee in the process of making the effect that not broken needle, bouncing pilotage also make integral product not delamination under high-temperature condition.Next has solved the problem of cotton diameter of glass and the trickle intensity difference of length; More loose porous because of the glass cotton once more, simple sewing up with aluminium foil causes glass fibre to fly silk afterwards easily, enter into air and cause operative employee's respiratory tract infection, simultaneously product also lacks certain stiffness, then both can solve glass fibre and flies the stiffness that a problem can strengthen product integral body and add the alkali-free fine cloth.
In sum, the fire-retardant aluminium foil glass cloth thickness that the utility model obtains is even, structure is loosened, is evenly distributed, the stretching resistance intensity height of warp, broadwise, be difficult for curling, have the good insulation of mechanical property, noise elimination, fire prevention and moistureproof, whole light weight, processing and simple installation in one, take plurality of advantages such as the little and good looking appearance of space, this product can be widely used in fields such as equipment pipe, construction wall.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the fire-retardant aluminium foil glass cloth that present embodiment is described mainly is made of aluminium foil 1, and the upper strata of aluminium foil 1 is provided with glass cotton 2, lower floor in glass cotton 2 is provided with alkali-free fine cloth 3, and the chain marshalling that constitutes by high silica glass line of described three-decker is knitted and is combined with each other.
Wherein:
Described aluminium foil 1 is thickness 0.1mm, 270g/m
