Description
The present invention relates to a multilayer structure for automobile interior materials and a method of manufacturing the same, and more particularly, to a multilayer structure for automobile interior materials having a multi-layer structure including a felt layer including natural fibers and synthetic fibers and a coating layer containing polyphenols, To a multilayer structure for automobile interior material.
Structures for automobile interior materials are made of materials to satisfy customers' stability, convenience, and functionality, and various materials and structures have been developed and applied accordingly. Conventional materials and structures focus on the functionality of automobiles, but as the industry develops and the quality of life of its customers improves, much attention is being paid to environmental aspects such as global environmental pollution and greenhouse gas emissions. In consideration of this, an environmentally friendly and lightweight material is required. Accordingly, natural fibers, bioplastics, and other lightweight materials are currently being researched and developed in many fields.
In general, automobile interior materials are composed of core layer, reinforcing layer, and skin layer. Typical multi-layer structures currently used include hand made felt, resin felt, natural fiber reinforced board, glass fiber / polyurethane foam, natural fiber sheet / polypropylene Foam and so on. Korean Patent Laid-Open No. 10-2004-0110668, which is a multi-layer structure such as natural fiber sheet / polypropylene foam, is receiving the spotlight as an eco-friendly and lightweight material which is requested by customers.
However, in the process of molding a structure for an automobile interior using natural fibers, natural fibers may be carbonized by high temperature molding conditions, resulting in the emission of odors and aldehydes. These disadvantages are hampering the expansion of automobile interior materials using natural fibers.
In addition, regulations for VOCs (volatile organic compounds) and aldehydes, which are harmful to human bodies, are being expanded worldwide in new cars or new homes. In particular, aldehydes are very toxic, As a harmful substance, it is difficult to continuously apply it to automobile materials or construction materials without improvement thereof. Accordingly, there is a need to develop an environmentally friendly automobile interior material for which the emission of odor is suppressed while applying natural fibers, and the concentration of toxic substances such as aldehydes is reduced.
It is an object of the present invention to provide a multilayer structure for automobile interior materials and a method of manufacturing the same.
An object of the present invention is to provide a multilayer structure for automotive interior materials capable of reducing the concentration of toxic substances such as aldehydes and suppressing the emission of odor, and a method for producing the same.
It is an object of the present invention to provide a multi-layer structure which is excellent in warmth, car sound and sound absorption and which can be used as an interior material for a vehicle such as a rear shelf, a door trim, a headliner, a trunk mat, a flooring material, a ceiling material and a bonnet liner.
Other objects and advantages of the present invention will become more apparent from the following detailed description of the invention and claims.
The embodiments of the present invention are described in order to more fully explain the present invention to those skilled in the art, and the following embodiments may be modified into various other forms, It is not limited to the embodiment. Rather, these embodiments are provided so that this disclosure will be more faithful and complete, and will fully convey the scope of the invention to those skilled in the art.
In the drawings, the thickness and size of each layer are exaggerated for convenience and clarity of description, and the same reference numerals refer to the same elements in the drawings. As used herein, the term "and / or" includes any and all combinations of one or more of the listed items.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a," "an," and "the" include singular forms unless the context clearly dictates otherwise. Also, " comprise "and / or" comprising "when used herein should be interpreted as specifying the presence of stated shapes, numbers, steps, operations, elements, elements, and / And does not preclude the presence or addition of one or more other features, integers, operations, elements, elements, and / or groups.
In one embodiment of the present invention, the present invention provides a method comprising: a) preparing a felt layer comprising natural fibers and synthetic fibers; And b) spraying a polyphenol aqueous solution onto one surface of the felt layer of step a) to form a coating layer.
The present invention relates to a multi-layer structure which is excellent in thermal insulation, sound insulation and sound absorption, which is a basic effect for an automobile interior material, and which can be utilized as an interior material for a vehicle such as a rear shelf, a door trim, a headliner, a trunk mat, a flooring material, a ceiling material, will be. Since the multi-layered structure of the present invention further includes a coating layer formed by spraying a polyphenol aqueous solution, it suppresses the emission of odors and toxic substances such as aldehydes that may occur due to the carbonization of natural fibers during the molding of the interior material structure can do. That is, the polyphenol coating layer adsorbs odor and toxic substances generated in the carbonization process of the natural fiber, thereby suppressing the release of the interior material to the outside.
In one embodiment of the present invention, the step of producing the felt layer of the step a) of the manufacturing method of the present invention is to be produced by a needle punching method.

When the synthetic fiber is contained in an amount exceeding 50% by weight, When the natural fiber is contained in an amount of less than 50% by weight, the rigidity and heat resistance of the substrate are deteriorated. When the natural fiber is contained in an amount exceeding 60% by weight, the effect of improving the odor is small and the cost saving effect is also insignificant.
In one embodiment of the present invention, the polyphenol aqueous solution of step b) of the method of the present invention is sprayed within 1 to 5% of the weight of the natural fiber of the felt layer. In spraying the polyphenol aqueous solution, , The amount of odor and aldehyde released is not reduced. When the injection amount is 5% or more, polyphenol is excessively applied, resulting in defects such as steam emission during molding.
In one embodiment of the present invention, the present invention further comprises a step of laminating a skin layer on the upper surface of the coating layer after step b). More specifically, the polyphenol aqueous solution is sprayed to the surface of the felt layer 100 formed by the needle punching process of the fresh weft fibers and the synthetic fibers at 1 to 5% of the weight of the natural fibers to form a coating layer, and the skin layer 300 is sequentially , And then processed using a mold to produce a lightweight multilayer structure.
The skin layer is a polyolefin nonwoven fabric or a polyester nonwoven fabric, and is not limited to the examples.
A method of manufacturing a multilayer structure for an interior automotive vehicle according to the present invention comprises the steps of: a) forming a felt layer through a needle punching process of natural fibers and synthetic fibers; And b) forming a coating layer by spraying a polyphenol solution onto the felt layer.
