Abstract
The utility model discloses a composite substrate for an automobile roof, which is characterized by comprising a polyurethane (PU) foam board (1), an upper glue powder layer (2) and a lower glue powder layer (3) are respectively arranged above and below the PU foam board (1), an upper polyester fiber cotton layer (4) is arranged on the upper glue powder layer (2), a lower polyester fiber cotton layer (5) is arranged below the lower glue powder layer (3), and a high polymer hot melt glue film (60 is arranged on the upper polyester fiber cotton layer (4). The composite substrate with low finished product cost has the advantages of external rigidity, stretching resistance, no deformation, excellent sound absorption performance, odorlessness, stable performance, safety, environmental protection, light weight and the like, and importantly omits glass fibers easy to harm human bodies and environments.
Description
Technical field:
The utility model relates to the automotive trim technical field, is a kind of new construction roof of the vehicle composite base material specifically, is applicable to the inner decorative ceiling of manned vehicle.
Background technology:
At present, conventional roof of the vehicle matrix structure is " PET nonwoven fabrics+rubber powder+hot-fusible high-molecular glued membrane+glass fibre+PU cystosepiment+glass fibre+rubber powder+hot-fusible high-molecular glued membrane " structure, wherein glass fibre mainly act as the enhancing rigidity of base material, hot body is allergic, the glass fibre floating debris causes certain influence to ambient air quality but glass fibre rises easily, in the suction body human body is caused certain harm, and the highly stable recycling that is difficult to degrade of glass fibre chemical property is unfavorable for environmental protection; In addition, what above-mentioned roof of the vehicle played sound-absorbing effect with base material mainly is the PU cystosepiment, and other materials does not have sound absorption, and base material integral structure sound-absorbing effect is poor; Flame resistance mainly increases fire retardant by the PU cystosepiment and plays fire retardation, because there is penetrating odor in fire-retardant its, thereby influences flame retardant effect for the strict qualification that is added with of the smell sex flame retardant of controlling the PU cystosepiment.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of roof of the vehicle composite base material is provided, and solves mainly that existing roof of the vehicle base material is detrimental to health, the feature of environmental protection is poor, problem such as sound-absorbing effect difference and poor fire.
In order to achieve the above object, the utility model is achieved in that a kind of roof of the vehicle composite base material, its special character is that it comprises the PU cystosepiment, the PU cystosepiment is upper and lower to be respectively gluing bisque and following rubber powder layer, establishing the cotton layer of poly-ester fibres on the gluing bisque, setting the cotton layer of poly-ester fibres under the rubber powder layer down, on the cotton layer of last poly-ester fibres, establish the hot-fusible high-molecular glued membrane.
The polyester fiber of the cotton cause 100% of poly-ester fibres is made, and its characteristic is as follows:
1. sound insulation: the polyester fiber acoustical cotton is a kind of aerated materials, and it can make sound form backflow in its cavity by the special high density tissue of fiber, realize sound-absorbing sound insulation function effectively.
2. flame resistance: the detection that experimentizes at NFA equipment quality control surveillance center of polyester fiber acoustical cotton reaches building materials combustion performance B1 level.
3. the feature of environmental protection: this product does not contain formaldehyde, and is harmless, through repeatedly experiment showed, it human body skin do not had any allergic phenomena, can use by secondary, destroys easily, and environment is not had secondary pollution.
4. stable: structure is tight, form stable, has higher tensile properties.Very light in weight, construction safety is convenient.Water-fast, drainage is strong after the water logging, and sound absorption qualities does not descend, and form is constant.
The good characteristic that is possessed according to above-mentioned poly-ester fibres cotton, add the more satisfactory PU cystosepiment of effect of heat insulation in the poly-ester fibres cotton on as the basis on top layer, the PU cystosepiment possesses lighting, themoplasticity, characteristics that intensity is moderate simultaneously, can fill up the shortcoming that the cotton mold pressing ceiling of simple poly-ester fibres grammes per square metre is higher, intensity is crossed win.
Compared with the prior art a kind of roof of the vehicle described in the utility model has following good effect with composite base material: 1, the ceiling finished product has outer good rigidity, intensity height, indeformable, sound absorption qualities is good, odorlessness, stable performance, safety and environmental protection, characteristics such as in light weight; 2, the poly-ester fibres cotton preferably tensile property can satisfy moderate finite deformation roof of the vehicle mold pressing requirement and the situation of tearing not occur; 3, cost of product is low, and sufficient application of raw material is not subjected to any restriction.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, describe a kind of roof of the vehicle composite base material of the utility model in detail below in conjunction with accompanying drawing.
Embodiment 1, referring to Fig. 1, according to different product require to choose the PU cystosepiment of certain density and specification, necessarily fabric width and grammes per square metre the poly-ester fibres cotton with and hot-fusible high-molecular glued membrane, the rubber powder of cohesive action, with above material according to the following cotton layer 5 of poly-ester fibres, down rubber powder layer 3, PU cystosepiment 1, gluing bisque 2, go up the cotton layer 4 of poly-ester fibres, hot-fusible high-molecular glued membrane 6 order from bottom to up enters compounding machine and carries out compound, the compound tense temperature is 180 ℃, behind compound the finishing as required behind the size trimming as the base material finished product.
Roof of the vehicle composite base material of the present utility model is applicable to that the inner decorative ceiling of manned vehicle, composite base material are heated to softening degree and guarantee the abundant fusion of top layer glued membrane, then sheet material is spread out of to carry out mold pressing with lining and get final product.
Claims (1)
1. roof of the vehicle composite base material, it is characterized in that it comprises PU cystosepiment (1), PU cystosepiment (1) is upper and lower to be respectively gluing bisque (2) and following rubber powder layer (3), on gluing bisque (2), establish the cotton layer of poly-ester fibres (4), setting the cotton layer of poly-ester fibres (5) under the rubber powder layer (3) down, on the cotton layer of last poly-ester fibres (4), establish hot-fusible high-molecular glued membrane (6).
