Abstract
The utility model discloses a fine sound absorption non-woven fabrics of glass relates to sound absorption non-woven fabrics technical field, including first cotton, the first sound sponge that absorbs of last fixed surface of first cotton is connected with, the last fixed surface of first sound sponge that absorbs is connected with the gauze, the bleeder vent has been seted up on the gauze, the sound sponge is inhaled to the last fixed surface of gauze is connected with the second, the second inhales the sound sponge's last fixed surface and is connected with the second cotton. The utility model discloses a set up first cotton and second cotton, because the material characteristic of cotton, fine gas permeability and absorptivity have, can the partial noise of active absorption, inhale the sound sponge through setting up first sound absorption sponge and second, because first sound absorption sponge and second inhale the sound sponge and be unevenness's structure, unevenness's structure can make the noise irregularly carry out a large amount of reflection consumptions in inhaling the sound sponge, thereby absorb a large amount of noises, because the network structure of gauze, the durable intensity has also been increased.
Description
Technical Field
The utility model relates to a sound absorption non-woven fabrics technical field specifically is a fine sound absorption non-woven fabrics of glass.
Background
Acoustical nonwoven, also known as nonwoven, is comprised of oriented or random fibers. It is called a cloth because of its appearance and certain properties. The sound absorption non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich color, low price, recycling and the like, and is suitable for industries such as agricultural films, shoemaking, leather making, mattresses, primary and secondary quilts, decoration, chemical engineering, printing, automobiles, building materials, furniture and the like.
The existing sound absorption non-woven fabric has a complex structure, poor sound absorption effect and low strength, and is not suitable for occasions with higher strength requirements.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides a fine sound absorption non-woven fabrics of glass has solved the fine sound absorption non-woven fabrics structure of the current glass who proposes in the above-mentioned background art complicacy, and sound absorbing effect is poor, and intensity is lower, is not applicable to the problem to the occasion that intensity requirement is higher.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the utility model provides a fine sound absorption non-woven fabrics of glass, includes first cotton, the first sound sponge of inhaling of last fixed surface of first cotton is connected with, the last fixed surface of first sound sponge is connected with the gauze, the bleeder vent has been seted up on the gauze, the sound sponge is inhaled to the last fixed surface of gauze is connected with the second, the sound sponge is inhaled to the second last fixed surface of sound sponge is connected with the second cotton.
Furthermore, the outer surface of first cotton and second cotton is coarse fine surface.
Further, the outer surface of the first sound absorption sponge is arranged into a regular convex-concave structure.
Furthermore, the air holes are arranged in a plurality of numbers and are uniformly distributed on the gauze.
Further, the sound sponge is inhaled to the second sets up to a plurality ofly, and is a plurality of sound sponge is inhaled to the second and is the protruding type structure of not uniform size.
(III) advantageous effects
The utility model provides a fine sound absorption non-woven fabrics of glass possesses following beneficial effect:
(1) this fine sound absorption non-woven fabrics of glass, through setting up first cotton and second cotton, because the material characteristic of cotton, fine gas permeability and absorptivity have, can the partial noise of active absorption, inhale the sound sponge through setting up first sound absorption sponge and second, because first sound absorption sponge and second inhale the sound sponge and be unevenness's structure, unevenness's structure can make the noise irregularly carry out a large amount of reflection consumptions in inhaling the sound sponge, thereby absorb a large amount of noises, through setting up the gauze in the intermediate level, because the sound absorption network structure of gauze, thereby make this fine sound absorption non-woven fabrics of glass have fine gas permeability, durable strength has also been increased.
Drawings
Fig. 1 is a schematic sectional view of the glass fiber sound absorption nonwoven fabric structure of the present invention.
In the figure: 1. a first cotton cloth; 2. a first sound absorbing sponge; 3. gauze; 4. air holes are formed; 5. a second sound absorbing sponge; 6. and a second cotton cloth.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
Referring to fig. 1, the present invention provides a technical solution:
a glass fiber sound absorption non-woven fabric comprises a first cotton cloth 1, wherein a first sound absorption sponge 2 is fixedly connected to the upper surface of the first cotton cloth 1, the outer surface of the first sound absorption sponge 2 is arranged to be a regular convex-concave structure, the concave-convex structure can enable noise to be irregularly reflected and consumed in the sound absorption sponge, so that a large amount of noise is absorbed, a gauze 3 is fixedly connected to the upper surface of the first sound absorption sponge 2, air holes 4 are formed in the gauze 3, a plurality of air holes 4 are formed in the air holes 4, the gauze 3 is uniformly distributed on the gauze 3, the gauze 3 is arranged in the middle layer, due to the net-shaped structure of the gauze 3, the glass fiber sound absorption non-woven fabric has good air permeability, the durable strength is also increased, a second sound absorption sponge 5 is fixedly connected to the upper surface of the gauze 3, the second sound absorption sponge 5 is arranged to be a plurality, the second sound absorption sponges 5 are of convex structures with different sizes, the second inhales sound sponge 5's last fixed surface and is connected with second cotton 6, and the surface of first cotton 1 and second cotton 6 is coarse fine surface, can make the reflection of sound weaken like this, can the partial noise of effective absorption.
