Abstract
The utility model discloses an automobile door plate sound insulation pad which comprises a cotton layer, a cementing layer and a non-woven fabric layer. The cotton layer is made of hollow polyester short fiber cotton, and the cementing layer is made of hot melting fibers with the melting point lower than 150 DEG C. According to the automobile door plate sound insulation pad, the defects of the automobile door plate sound insulation pad formed by compositing a layer of polyester materials and a layer of polypropylene fiber cotton can be overcome, the hollow polyester short fiber cotton has more superior sound insulation performance, heat insulation performance and safety performance than the polypropylene fiber cotton, and an automatic flame retarding effect can be achieved without adding fire retardants.
Description
Technical field
The utility model relates to automotive upholstery material technology field, is specifically related to a kind of automobile door plate sound insulating pad.
Background technology
Patent documentation CN202271602U disclosed " automobile door plate sound insulating pad " provides a kind of automobile door plate sound insulating pad, by polyester material and cotton two-layer being composited of mekralon.It has mainly used the performance of polyester material impact strength height, high-low temperature resistant, strong in conjunction with the cotton loft of mekralon, as not to be afraid of extruding, good springiness characteristics, thereby make the environmental protection of comprehensive both advantages, nontoxic automobile door plate sound insulating pad product, overcome that all kinds of automobile door plate sound insulating pad products use not environmental protection of material in the prior art, contained the problem of objectionable impurities or irritative gas.
But still there is the perfect place of some needs in the disclosed automobile door plate sound insulating pad of above-mentioned document: at first, the higher temperature of the cotton two-layer compound needs of polyester material and mekralon could realize the fusion applying, the processing technology energy consumption is higher, and can destroy the loft of chemical fiber under the high temperature, cause excessive gummed, thereby reduced sound insulation, the effect of heat insulation of automobile door plate sound insulating pad; And the employing adhesive, compound polyester material and mekralon cotton can increase the use cost of adhesive again, and adhesive is introduced not environmental protection easily, contained the problem of objectionable impurities or irritative gas; Secondly, the cotton two-layer automotive compounded door-plate sound insulating pad of polyester material and mekralon also needs to use adhesive on being fixed on the automobile door plate inwall time, therefore introduces not environmental protection easily, contains the problem of objectionable impurities or irritative gas.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile door plate sound insulating pad, can overcome the existing deficiency of the cotton two-layer automotive compounded door-plate sound insulating pad of above-mentioned polyester material and mekralon.
To achieve these goals, the technical scheme that the utility model proposes is:
A kind of automobile door plate sound insulating pad is provided, comprises cotton layer, cementing layer, nonwoven layer; Described cotton layer is the hollow pet staple fiber cotton, and described cementing layer is that fusing point is lower than 150 ℃ meldable fibre.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 the further improved automobile door plate sound insulating pad of the utility model, it is characterized in that: also comprise laminating layer, described laminating layer is positioned at cotton layer upper surface, and described laminating layer is that fusing point is lower than 150 ℃ meldable fibre.Be convenient to the automobile door plate sound insulating pad is fixed on the automobile door plate inwall 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 the further improved automobile door plate sound insulating pad of the utility model, it is characterized in that: the fibre fineness of the hollow pet staple fiber cotton of described cotton layer was 3 dawn～6 dawn.
As the further improved automobile door plate sound insulating pad of the utility model, it is characterized in that: the quantitative specification of the hollow pet staple fiber cotton of described cotton layer is the every square meter of 350 grams～every square meter of 450 grams, and the thickness of described polyster fibre cotton is 5 millimeters～15 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 the further improved automobile door plate sound insulating pad of the utility model, it is characterized in that: it is Korea S's 4080 low-melting fibers that described fusing point is lower than 150 ℃ meldable fibre.
Automobile door plate sound insulating pad provided by the utility model, not only overcome the higher temperature of the cotton two-layer compound needs of polyester material and mekralon and could realize the fusion applying, the processing technology energy consumption is higher, and can destroy the loft of chemical fiber under the high temperature, cause excessive gummed, thereby reduced the sound insulation of automobile door plate sound insulating pad, the problem of effect of heat insulation; And adopt adhesive to increase compound polyester material and the cotton use cost of mekralon, and adhesive is introduced not environmental protection easily, is contained the problem of objectionable impurities or irritative gas.And the hollow pet staple fiber cotton has sound insulation, the heat-proof quality of more excellent benefit than mekralon cotton, and safety performance, and need not to add fire retardant can realize from flame retardant effect.
Description of drawings
Fig. 1, automobile door plate sound insulating pad structural representation.
1 is cotton layer, and 2 is nonwoven layer, and 3 is cementing layer, and 4 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.
As shown in Figure 1, the automobile door plate sound insulating pad that present embodiment provides comprises cotton layer 1, cementing layer 3, nonwoven layer 2; Described cotton layer 1 is the hollow pet staple fiber cotton, and described cementing layer 3 is 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.And the hollow pet staple fiber cotton replaced the mekralon cotton, has sound insulation, the heat-proof quality of more excellent benefit, and safety performance, and need not to add fire retardant can realize from flame retardant effect.
The fibre fineness of the hollow pet staple fiber cotton of described cotton layer 1 was 3 dawn～6 dawn.The quantitative specification of the hollow pet staple fiber cotton of described cotton layer 1 is the every square meter of 350 grams～every square meter of 450 grams, and the thickness of described polyster fibre cotton is 5 millimeters～15 millimeters.It is Korea S's 4080 low-melting fibers that described fusing point is lower than 150 ℃ meldable fibre.
Further improved, described automobile door plate sound insulation is paid somebody's debt and expected repayment later and is comprised laminating layer 4, and described laminating layer 4 is positioned at cotton layer 1 upper surface, and described laminating layer 4 is lower than 150 ℃ meldable fibre for fusing point.Be convenient to the automobile door plate sound insulating pad is fixed on the automobile door plate inwall by setting up described laminating layer 6, need not additionally to use other chemical adhesive when mounted, easy to process, save cost and Environmental Safety.
