Abstract
The utility model discloses an automobile front wall sound insulating pad which is composed of five layers of materials, namely a top layer, a base layer, a middle layer, a first connection layer between the base layer and the middle layer, and a second connection layer between the top layer and the middle layer. The middle layer is made of hollow polyester short fiber cotton, the top layer and the base layer are made of polyester fibers and polypropylene fiber mixed cotton, and the first connection layer and the second connection layer are made of hot melting fibers with the melting point lower than 150 DEG C. According to the automobile front wall sound insulating pad, on one hand, the problem that existing automobile front wall sound insulating materials have poisonous and harmful substances or irritant gases is overcome and the problem that poisonous and harmful substances or irritant gases are introduced by a large number of chemical adhesives used in the processing process is overcome, and therefore the environment-friendly performance, the health performance and the safety performance of decoration parts in an automobile are improved. On the other hand, the high-performance effects of insulating sound, insulating heat and damping of the automobile front wall sound insulating pad can be achieved.
Description
Technical field
The utility model relates to automotive upholstery material technology field, is specifically related to enclose sound insulating pad before a kind of automobile.
Background technology
Enclosing sound insulating pad before the automobile is a kind of automotive upholstery that is positioned at car engine guard shield inboard, and its radical function is to intercept and absorb the noise that car engine sends when travelling, and has damping, effect such as heat insulation.
Enclosing sound insulating pad before the existing automobile is mainly made by materials such as polyester cotton, sponge foaming, particularly, as patent documentation CN202016441U disclosed " enclosing sound insulating pad before the automobile ", patent documentation CN201544883U disclosed " enclosing sound insulating pad before a kind of new automobile " etc.Materials such as polyester cotton, sponge foaming material itself on the one hand contain poisonous and harmful or irritative gas easily, a large amount of chemical adhesives that use are also introduced hazardous and noxious substances or irritative gas easily in the processing technology on the other hand, thereby influence environmental protection, the health and safety performance of automotive upholstery.
Enclose sound insulating pad before the automobile of patent documentation CN201800647U disclosed " enclosing sound insulating pad before a kind of automobile " employing hard polyster fibre cotton, hard polyster fibre and the cotton three-decker of making of mekralon mixing, enclosure sound cushion material itself contains the problem of poisonous and harmful or irritative gas easily before having solved automobile, and has callable advantage.But still remain further to be solved for a large amount of problems of using chemical adhesive to introduce hazardous and noxious substances or irritative gas in the processing technology, and find in actual use, the disclosed polyster fibre grammes per square metre of CN201800647U and thickness range all need further adjustment, to satisfy the performance requriements that encloses sound insulating pad sound insulation, heat insulation, damping before the automobile.
Summary of the invention
The purpose of this utility model is enclosed sound insulating pad before being to provide a kind of automobile, can overcome the problem that the preceding enclosure sound cushion material of existing automobile itself contains poisonous and harmful or irritative gas easily on the one hand, the chemical adhesives that can overcome a large amount of uses in the processing technology are simultaneously introduced the problem of hazardous and noxious substances or irritative gas, thereby improve environmental protection, the health and safety performance of automotive upholstery.Can also realize sound insulation, heat insulation, the cushioning effect effect of the preceding enclosure sound bed hedgehopping performance of automobile on the other hand.
To achieve these goals, the technical scheme that the utility model proposes is:
Enclose sound insulating pad before a kind of automobile is provided, by the articulamentum two between articulamentum one, top layer and the interlayer between top layer, bottom, interlayer and bottom and the interlayer, amount to five layer materials and constitute; Described interlayer is the hollow pet staple fiber cotton, and described top layer and described bottom are that polyster fibre and mekralon mix cotton, and described articulamentum one and described articulamentum two are lower than 150 ℃ meldable fibre for fusing point.By using fusing point to be lower than 150 ℃ meldable fibre as adhesive, thereby overcome the problem that hazardous and noxious substances or irritative gas are introduced in the use of conventional chemical adhesion agent.
As enclosing sound insulating pad before the further improved automobile of the utility model, also comprise laminating layer, described laminating layer is positioned at the top layer upper surface, and described laminating layer is that fusing point is lower than 150 ℃ meldable fibre.Be convenient to enclose on the inwall before sound insulating pad is fixed on automobile enclosing before the automobile by setting up described laminating layer, need not additionally to use other chemical adhesive when mounted, easy to process, save cost and Environmental Safety.
As enclosing sound insulating pad before the further improved automobile of the utility model, the fibre fineness of the hollow pet staple fiber cotton of described interlayer was 3 dawn～6 dawn.
As enclosing sound insulating pad before the further improved automobile of the utility model, the quantitative specification of the hollow pet staple fiber cotton of described interlayer is the every square meter of 450 grams～every square meter of 550 grams, and the thickness of described polyster fibre cotton is 8 millimeters～20 millimeters.The grammes per square metre of hollow pet staple fiber cotton is lighter, and namely structure is comparatively fluffy, and elasticity is bigger, and rigidity descends, and thickness is bigger, so damping effect is better, and sound insulation, heat-blocking action effect also promote to some extent.
As enclosing sound insulating pad before the further improved automobile of the utility model, it is Korea S's 4080 low-melting fibers that described fusing point is lower than 150 ℃ meldable fibre.
Enclose sound insulating pad before the automobile provided by the utility model, can overcome the problem that the preceding enclosure sound cushion material of existing automobile itself contains poisonous and harmful or irritative gas easily on the one hand, the chemical adhesives that can overcome a large amount of uses in the processing technology are simultaneously introduced the problem of hazardous and noxious substances or irritative gas, thereby improve environmental protection, the health and safety performance of automotive upholstery.Can also realize sound insulation, heat insulation, the cushioning effect effect of the preceding enclosure sound bed hedgehopping performance of automobile on the other hand.
Description of drawings
Enclosure sound mat structure scheme drawing before Fig. 1, automobile.
1 is top layer, and 2 is bottom, and 3 is interlayer, and 4 is that articulamentum one, 5 is that articulamentum two, 6 is laminating layer.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection domain.
Embodiment one:
As shown in Figure 1, enclose sound insulating pad before the automobile that present embodiment provides, by the articulamentum 25 between articulamentum 1, top layer and the interlayer between top layer 1, bottom 2, interlayer 3 and bottom and the interlayer, amount to five layer materials and constitute; Described interlayer 3 is the hollow pet staple fiber cotton, and described top layer 1 and described bottom 2 are that polyster fibre and mekralon mix cotton, and described articulamentum 1 and described articulamentum 25 are lower than 150 ℃ meldable fibre for fusing point.By using fusing point to be lower than 150 ℃ meldable fibre as adhesive, thereby overcome the problem that hazardous and noxious substances or irritative gas are introduced in the use of conventional chemical adhesion agent.
