The rubber-plastic foamed goods such as PE Foam (EPE), rubber and plastic (EVA, PEF, EPDM, CR etc.), XPE/IXPE in embodiment 1-4.China has a large amount of motor vehicle liquidations every year, the inside gadget of abandoned car is as PE Foam (EPE), rubber and plastic (EVA, PEF, EPDM, CR etc.), the rubber-plastic foamed goods such as XPE/IXPE are difficult to degrade in a short time, for avoiding environmental pollution, the rubber-plastic foamed goods reclaimed after utilizing motor vehicle liquidation, comparatively small-particle is ground into by after its cleaning and dewatering, after hyperthermia drying sterilization, be uniformly mixed with the fire retardant ratio of PE thermal fusing powder and aluminium hydroxide, above-mentioned compound is hot pressed on aluminium foil regeneration rubber-plastic foam thin slice, this regeneration rubber-plastic foam flake side is combined with fire-retardant butyl rubber stick gluing, butyl rubber adhesive coating layer covers and is convenient to transport and stores separate-type paper protective layer 4, it is firm that another side passes through thermal fusing powder or hot melt nonwoven layer of cloth and bonding foil, and the effect of aluminium foil is to provide resistant to elevated temperatures protective layer and promotes the ability of sheet material obstruct noise further, just produce " aluminum sheet is covered in a kind of regeneration rubber-plastic foam mixing compacting of heat-insulating sound-insulating " through above-mentioned technological process, this technical field is the cycling and reutilization technology of macromolecular material, " aluminum sheet is covered in a kind of regeneration rubber-plastic foam mixing compacting of heat-insulating sound-insulating " because it is lightweight and closely knit, good springiness, fire-retardant, heat insulation performance is effective, it is good that butyl rubber stick and regeneration rubber-plastic foam have damping vibration attenuation, environment-protective no-smell can be used in automotive upholstery in a large number, the effect played sound insulation vibration damping He reduce costs.Throw off separate-type paper protective layer 4 during use, namely fire-retardant butyl rubber stick just can glue the bottom of the outside surface being posted on truck driver room, thus forms a sound-insulating and heat-insulating and the barrier of vibration damping between the bottom of outside surface in truck driver room and engine compartment.
Butyl rubber stick is elastomeric one, is synthesized, be mixed into the fire retardant of aluminium hydroxide by iso-butylene and a small amount of isoprene.Add the fire retardant of aluminium hydroxide in butyl rubber stick, make fire-retardant butyl rubber stick; Generally be used in inside auto sound articles for use, nontoxic, be environment-friendly materials.
The fire retardant mechanism of aluminium hydroxide: be mixed with Al (OH)
3superpolymer, when temperature rises to 250 ~ 300 DEG C, Al (OH)
3just absorb heat and discharge steam in a large number, superpolymer temperature rise speed being slowed down, degrades and slow down.Al (OH) simultaneously
3the steam that decomposes discharges, has rushed inflammable gas rare, and slow down combustionvelocity.In addition, aluminium hydroxide dehydration, absorbing and cooling temperature, make superpolymer can not Thorough combustion, forms charing protective membrane, both stopped entering of oxygen, and also blocked the effusion of inflammable gas on surface.This carbonization process avoids the formation of cigarette ash, and therefore aluminium hydroxide fire retardant not only has good anti-flaming function, also has good to press down hood.Aluminium hydroxide fire retardant is applied: aluminium hydroxide fire retardant, is widely used in latex product, crosslinked polyethylene insulation material, in the polyester of glass strengthening tree and PVC product.This fire retardant is mineral compound, nontoxic, does not produce secondary pollution.
The effect of aluminium foil is to provide resistant to elevated temperatures protective layer and promotes the ability that sheet material intercepts noise further.
