Abstract
The utility model discloses a protective film made of insulating fire-retardant material for an exterior wall of a building. The protective film comprises an aluminized glass fiber mesh cloth layer, an aluminum layer, a PET (polyethylene terephthalate) polyester layer, a two-way stretched nylon layer, an aluminum layer, a two-way stretched nylon layer and a composite polyethylene layer from outside to inside. Compared with the prior art, the protective film has the following advantages that a flexible packaging material has good flatness, and excellent blocking effects and aging resistance can be realized. The protective film is packaged outside a sheet. In addition to a function of protection, cement and adhesives can be blocked, and the temperature, noise and the like can also be blocked.
Description
Technical field
The utility model belongs to the fire proofing diaphragm, particularly STP building exterior wall heat preserving fire proofing diaphragm.
Background technology
STP sheet material is current at the emerging a kind of exterior-wall heat insulation fire proofing of building trade.This material heat insulation effect is excellent, and coefficient of thermal conductivity is lower than 0.008w/ (mK), and thickness only has 1 centimetre, and this is the important breakthrough of technology in the insulation industry.Normally used in the past is EPS sheet material, and thickness is about 6 centimetres to 8 centimetres, and the existing equal incendivity of conventional heat insulating material.The thickness of STP plate only is 1/8th of common heat insulating material, and the heat-insulating and fire-proof better effects if.The product unit mass is light, and every square metre weight is about 12 kilograms behind the upper wall, only be on the ceramic tile weight behind the wall 1/4.After the construction, difficult drop-off, safe.The thickness of heat insulating material can increase user's usable floor area after reducing, and reduces shared area.The heat insulation effect of STP plate material is equivalent to 5 times of conventional polyphenyl plate, 4 times of extruded sheet, 3 times of polyurethane.And this heat insulating material is inorganic heat insulation material, and fire prevention is not fired; Nontoxic, environmental protection, long service life, can with the same equivalent life of building.Can be widely used in newly-built, as to extend civilian and utilities building exterior wall and roofing heat insulating work, be particularly useful for the reducing energy consumption engineering of existing building.
Because the barrier of STP sheet material own is had relatively high expectations, packaging film itself is thicker, and producting process difficulty is larger, and it is not high that surface finish easily occurs, the phenomenons such as gauffer.If surface irregularity has gauffer, not only affect the outward appearance of the STP sheet material of packing, also will affect the heat insulation and heat insulation effect of finished product STP outer wall board for building.
The utility model content
Technical problem to be solved in the utility model provides the good STP building exterior wall heat preserving fire proofing diaphragm of a kind of surface finish.
The technical scheme of the utility model technical solution problem is: STP building exterior wall heat preserving fire proofing diaphragm is respectively aluminium-coated glass-fibre grid layer of cloth, aluminium lamination, PET polyester layer, biaxial tension nylon layer, aluminium lamination, biaxial tension nylon layer, composite polyethylene layer from outside to inside.
Preferred STP building exterior wall heat preserving fire proofing diaphragm is: be from outside to inside: aluminium-coated glass-fibre grid cloth/7 μ mAL/12 μ mPET/15 μ mBOPA/7 μ mAL/15 μ mBOPA/80 μ m composite polyethylene layers.
Outermost layer of the present utility model has been selected fiberglass gridding cloth.This material has following characteristics:
1, chemical stability is good.Alkali resistant, acidproof, water-fast, water-fast mud etch, and anti-other chemical attacks;
2 and resin-bonded property strong, be soluble in styrene etc.
3, high strength, high-modulus, lightweight.
4, good stability of the dimension, stiffening, smooth, be difficult for shrinkage strain, polarization is good.
5, impact resistance is better.(because of screen cloth intensity height, good toughness).
6, anti-ly go mouldy, insect protected.
Therefore 7, fire prevention, insulation, sound insulation, insulation are used for the insulation of building external and internal wall, waterproof, cracking resistance, fire-retardantly have a good effect.
The second layer and layer 5: adopt two aluminium foil structure designs.This product requirement has high barrier, so adopt AL as barrier layer.If adopt the thick aluminum foil of individual layer, easily produce in process of production and break, the phenomenons such as fold, and fracture very easily in the process of manufacture.Therefore, adopt the composite construction of double-deck thin aluminium foil, reduced difficulty of processing and processing cost.The simultaneously use of two-layer AL has improved obstruct intensity greatly, has reduced because the normal phase is used the possibility that causes layering, when ensureing barriering effect, has added the twice protective barrier more.In addition, it can effectively isolate ambient temperature to the impact of Indoor environment to excellent in barrier property such as light, oxygen and steam.
3-layer PET: biaxial tension pet film.This mechanical properties of materials is good, and its toughness is maximum in thermoplastic commonly used, and the hot strength of film can compare favourably with aluminium foil, and impact strength is 3～5 times of other film, and folding resistance is good.And it has good high and low temperature resistance, can use for a long time in 120 ℃ of temperature ranges, and short-term is used can anti-150 ℃ of high temperature, can anti--70 ℃ of low temperature, and very little on its mechanical performance impact during high and low temperature.Can guarantee preferably dimensional stability, the combination property that promoted product and the product specification of packaging material in the bag process.
The 4th layer and layer 6: adopt (BOPA) nylon.Nylon is polyamide; have good obdurability, tensile strength, elongation rate and abrasion resistance; has preferably physical and mechanical properties; can strengthen withstand voltage, shock-resistant, anti-puncture and the anti-performance such as fall of product after compound; can well protect the central AL of composite material, make it be difficult for wrinkle, fracture; ensure the environmental suitability of product, and cost is moderate.
The 7th layer of PE: have good hot sticky performance and ageing-resistant performance.Vacuumizing under the state, keeping good bond strength, do not revealing, indeformable.Can use for a long time during protection STP external wall material, layering does not occur in good environmental adaptability; Good physical and mechanical properties is arranged, can promote the deflection of packing;
The utility model compared with prior art has following characteristics: the flatness effect of flexible packing material is good, it is excellent in barriering effect, ageing-resistant to have.It is outside that the present invention is packaged in this sheet material, except playing defencive function, also plays the barriering effect to cement, bonding adhesive, and to barriering effects such as temperature, noises.
