Abstract
The invention discloses a kind of automobile roof sound insulation cushion, comprise top layer, interlayer, bottom; Described top layer is that hollow pet staple fiber is cotton, described interlayer be short felt and the fusing point cut of glass lower than the meldable fibre mixing Charge of 150 DEG C, described bottom is nonwoven fabrics.Automobile roof sound insulation cushion provided by the present invention, adopt polyster fibre cotton as sound insulation packing, nontoxic, and lightweight, under the condition of identical sound insulation value, vertical one-tenth net materials weight only has 60% of 50% of flexible polyurethane bipeltate or common non-woven material; The processing technology of automobile roof sound insulation cushion provided by the present invention does not relate to chemical reaction again, and recoverable, energy-conserving and environment-protective; In addition, the main material polyster fibre cotton of automobile roof sound insulation cushion provided by the present invention has flame retardant effect, without the need to adding fire retardant, and has good strainability, and dust containing capacity is large, long service life.
Description
Technical field
The present invention relates to material for car interior trim parts technical field, be specifically related to a kind of automobile roof sound insulation cushion.
Background technology
Automobile roof sound insulation cushion fits in a kind of automotive upholstery on automobile metal ceiling inwall, sound insulation, heat-blocking action are mainly used in, due to the higher and density of the usual permeability of heat of automobile metal ceiling and rigidity larger, therefore heat insulation and sound insulation is unfavorable for, need to fit on inwall one deck sound-heat insulated cushion, thus provide comfortable impression for navigating mate in car and passenger.
Existing automobile roof sound insulation cushion is made primarily of polypropylene fibre felt and similar blended felt or flexible polyurethane bipeltate, needs to use chemical adhesive in a large number in polypropylene fibre felt and similar blended felt material processing, and easily goes mouldy by water and weather effect; And for flexible polyurethane bipeltate, its material itself has toxicity, processing technology needs to pass through chemical reaction, energy consumption is higher, and this material not recoverable, easily cause environmental pollution, in addition also have chemical constitution unstable, oxidizable decomposition, does not have flame retardance, there is the shortcomings such as disaster hidden-trouble.
Summary of the invention
The object of the present invention is to provide a kind of automobile roof sound insulation cushion, existing Sound insulation pad for car carpet can be overcome and adopt polypropylene fibre felt and similar blended felt or flexible polyurethane foam rubbery material and Problems existing and deficiency.
To achieve these goals, the technical scheme that the present invention proposes is:
A kind of automobile roof sound insulation cushion is provided, comprises top layer, interlayer, bottom; Described top layer is that hollow pet staple fiber is cotton, described interlayer be short felt and the fusing point cut of glass lower than the meldable fibre mixing Charge of 150 DEG C, described bottom is nonwoven fabrics.Fusing point is used for gluing together nonwoven fabrics after high-temperature fusion lower than the meldable fibre of 150 DEG C and hollow pet staple fiber is cotton, the short felt of cutting of glass is for improving the effect of heat insulation of automobile roof sound insulation cushion, the mechanical strength of automobile roof sound insulation cushion can be improved simultaneously, and there is flame retardance, safety and environmental protection.
As the automobile roof sound insulation cushion that the present invention improves further, also comprise laminating layer, described laminating layer is positioned at top layer upper surface, and described laminating layer is fusing point lower than the meldable fibre of 150 DEG C.Be convenient to automobile roof sound insulation cushion is fixed on roof of the vehicle inwall by setting up described laminating layer, without the need to additionally using other chemical adhesive when mounted, easy to process, save cost and Environmental Safety.
As the automobile roof sound insulation cushion that the present invention improves further, the fibre fineness of the hollow pet staple fiber cotton of described top layer be 3 dawn ~ 8 dawn.
As the automobile roof sound insulation cushion that the present invention improves further, the quantitative specification of the hollow pet staple fiber cotton of described top layer is 600 grams of every square meter ~ 800 gram every square meters, and the thickness of described polyster fibre cotton is 15 millimeters ~ 40 millimeters.
As the automobile roof sound insulation cushion that the present invention improves further, described fusing point is Korea S 4080 low-melting fiber lower than the meldable fibre of 150 DEG C.
Automobile roof sound insulation cushion provided by the present invention, adopt polyster fibre cotton as sound insulation packing, nontoxic, and lightweight, under the condition of identical sound insulation value, vertical one-tenth net materials weight only has 60% of 50% of flexible polyurethane bipeltate or common non-woven material; The processing technology of automobile roof sound insulation cushion provided by the present invention does not relate to chemical reaction again, and recoverable, energy-conserving and environment-protective; In addition, the main material polyster fibre cotton of automobile roof sound insulation cushion provided by the present invention has flame retardant effect, without the need to adding fire retardant, and has good strainability, and dust containing capacity is large, long service life.
