Abstract
The invention discloses a kind of automobile door plate sound insulating pad, comprise cotton layer, cementing layer, nonwoven layer; Described cotton layer is hollow pet staple fiber cotton, and described cementing layer is fusing point lower than the meldable fibre of 150 DEG C. Automobile door plate sound insulating pad provided by the present invention, can overcome the existing deficiency of the cotton two-layer automotive compounded door-plate sound insulating pad of polyester material and polypropylene fibre, and hollow pet staple fiber cotton has sound insulation, the heat-proof quality of more excellent benefit than polypropylene fibre cotton, and security performance, can realize from flame retardant effect without adding fire retardant.
Description
Technical field
The present invention relates to material for car interior trim parts technical field, be specifically related to a kind of automobile door plate sound insulating pad.
Background technology
Patent documentation CN202271602U disclosed " sound insulation cushion for automobile door plate " provides a kind of automobile door plate sound insulating pad, by polyester material and cotton two-layer being composited of polypropylene fibre. It has mainly been applied, and polyester material impact strength is high, the performance of high-low temperature resistant, strong in conjunction with the cotton fluffy degree of polypropylene fibre, not to be afraid of extruding, good springiness feature, thereby make the environmental protection of comprehensive both advantages, nontoxic automobile door plate sound insulating pad product, overcome the problem that in prior art, all kinds of automobile door plate sound insulating pad products use not environmental protection of material, contain harmful substance or irritative gas.
But the disclosed automobile door plate sound insulating pad of above-mentioned document still exists some to need perfect place: first, the higher temperature of the cotton two-layer compound needs of polyester material and polypropylene fibre could realize melting laminating, processing technology energy consumption is higher, and under high temperature, can destroy the fluffy degree of chemical fibre, cause excessive gummed, thereby reduced sound insulation, the effect of heat insulation of automobile door plate sound insulating pad; And employing adhesive, composite terylene material and polypropylene fibre cotton can increase again the use cost of adhesive, and the adhesive problem easily introducing not environmental protection, contain harmful substance or irritative gas; Secondly, the cotton two-layer automotive compounded door-plate sound insulating pad of polyester material and polypropylene fibre, in the time being fixed on automobile door plate inwall, also needs to use adhesive, the problem that therefore easily introduce not environmental protection, contains harmful substance or irritative gas.
Summary of the invention
The object of the present invention 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 polypropylene fibre.
To achieve these goals, the technical scheme that the present invention proposes is:
A kind of automobile door plate sound insulating pad is provided, comprises cotton layer, cementing layer, nonwoven layer; Described cotton layer is hollow pet staple fiber cotton, and described cementing layer is fusing point lower than the meldable fibre of 150 DEG C. By use fusing point lower than the meldable fibre of 150 DEG C as adhesive, thereby overcome the use procedure of conventional chemical adhesive and introduced the problem of poisonous and harmful substance or irritative gas.
As the further improved automobile door plate sound insulating pad of the present invention, it is characterized in that: also comprise laminating layer, described laminating layer is positioned at cotton layer upper surface, described laminating layer is fusing point lower than the meldable fibre of 150 DEG C. Be convenient to automobile door plate sound insulating pad to be fixed on automobile door plate inwall by setting up described laminating layer, without additionally using when mounted other chemical adhesive, easy to process, save cost and Environmental Safety.
As the further improved automobile door plate sound insulating pad of the present invention, 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 present invention, it is characterized in that: the quantitative specification of the hollow pet staple fiber cotton of described cotton layer is 350 grams of every square meter～450 gram every square meters, 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 structure is comparatively fluffy, and elasticity is larger, and rigidity declines, and thickness is larger, and therefore 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 present invention, it is characterized in that: described fusing point is Korea S's 4080 low-melting fibers lower than the meldable fibre of 150 DEG C.
Automobile door plate sound insulating pad provided by the present invention, not only overcome the higher temperature of the cotton two-layer compound needs of polyester material and polypropylene fibre and could realize melting laminating, processing technology energy consumption is higher, and under high temperature, can destroy the fluffy degree of chemical fibre, 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 the cotton use cost of composite terylene material and polypropylene fibre, and the adhesive problem easily introducing not environmental protection, contain harmful substance or irritative gas. And hollow pet staple fiber cotton has sound insulation, the heat-proof quality of more excellent benefit than polypropylene fibre cotton, and security performance, can realize from flame retardant effect without adding fire retardant.
Brief description of the 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.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the automobile door plate sound insulating pad that the present embodiment provides, comprises cotton layer 1, cementing layer 3, nonwoven layer 2; Described cotton layer 1 is hollow pet staple fiber cotton, and described cementing layer 3 is fusing point lower than the meldable fibre of 150 DEG C. By use fusing point lower than the meldable fibre of 150 DEG C as adhesive, thereby overcome the use procedure of conventional chemical adhesive and introduced the problem of poisonous and harmful substance or irritative gas. And hollow pet staple fiber cotton replaced polypropylene fibre cotton, there is sound insulation, the heat-proof quality of more excellent benefit, and security performance, can realize from flame retardant effect without adding fire retardant.
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 350 grams of every square meter～450 gram every square meters, and the thickness of described polyster fibre cotton is 5 millimeters～15 millimeters. Described fusing point is Korea S's 4080 low-melting fibers lower than the meldable fibre of 150 DEG C.
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 fusing point lower than the meldable fibre of 150 DEG C. Be convenient to automobile door plate sound insulating pad to be fixed on automobile door plate inwall by setting up described laminating layer 6, without additionally using when mounted other chemical adhesive, easy to process, save cost and Environmental Safety.
