By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model thermoplasticity Sound-proof material one embodiment.
Fig. 2 is the structural representation of top layer one embodiment in thermoplasticity Sound-proof material in Fig. 1.
Fig. 3 is the structural representation of another embodiment of top layer in thermoplasticity Sound-proof material in Fig. 1.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
Please refer to Fig. 1, the utility model thermoplasticity Sound-proof material 100 comprises top layer 11, intermediate layer 12 and bottom 13, top layer 11, intermediate layer 12 and bottom 13 are mixed fiber layer, top layer 11, intermediate layer 12 and bottom 13 form thermoplasticity Sound-proof material 100 through hot pressing, wherein top layer 11 comprises the base portion 111 and the multiple lug bosses 112 be arranged on base portion 111 and depressed part 113 of fitting with intermediate layer 12, and the top of lug boss 112 and the bottom of depressed part 113 are respectively arranged with the through hole 114 running through top layer 11.
Concrete, mixed fiber layer is hot-forming by polyster fibre, low-melting fiber and blend fibre, and certainly, mixed fiber layer can also be made up of the fiber that other soundproof effects are good.Top layer 11 arranges lug boss 112 and depressed part 113, can realize eliminating the noise of different frequency, and then the frequency range of isolated noise can be increased, there is better soundproof effect.Simultaneously, the top of lug boss 112 and the bottom of depressed part 113 arrange through hole 114 respectively, thus air vibration in space can be caused when sound incides in through hole 114, due to the friction of the inwall of the viscosity resistance of air, air and through hole 114, quite a few acoustic energy is made to change into heat energy and be consumed; In addition, when air adiabatic compresses, between air and through hole 114, constantly there is heat exchange, due to conduction of heat, a part of acoustic energy also can be made to change into heat energy, thus reach the buffering effect to sound.
In the present embodiment, intermediate layer 12 is identical with the structure of bottom 13, all be rectangle or square platy structure, and the thickness of intermediate layer 12 and bottom 13 is 1 centimetre, the thickness of the base portion 111 of top layer 11 is 0.8 centimetre, the height of lug boss 112 and the degree of depth of depressed part 113 are 0.3 centimetre, certainly can also arrange top layer 11 as required, the thickness of intermediate layer 12 and bottom 13 is other value.
Compared with prior art, the utility model thermoplasticity Sound-proof material 100 by three layers of mixed fiber layer through hot-forming, and on top layer 11, be provided with lug boss 112 and depressed part 113, the top of lug boss 112 and the bottom of depressed part 113 arrange the through hole 114 running through top layer, this structure can effectively abate the noise, and has good soundproof effect.
Please refer to Fig. 2, Fig. 2 is the structural representation of top layer 11 1 embodiment in Fig. 1.As shown in Figure 2, top layer 11 comprises base portion 111 and the lug boss 112 that is arranged on base portion 111 and depressed part 113, the wherein tabular that is rectangle of base portion 111, lug boss 112 is the arc convex band extended along the width (i.e. Y-direction in Fig. 2) of base portion 111, depressed part is the arc-shaped recess band extended along the width of base portion 111, lug boss 112 and depressed part 113 are alternately distributed continuously and make the upper surface of base portion 111 in the longitudinal direction in sine wave shape on the length direction (i.e. X-direction in Fig. 2) of base portion 111, and the bottom of the top of lug boss 112 and depressed part 113 is distributed with multiple through hole 114.
Please refer to Fig. 3 again, Fig. 3 is the structural representation of another embodiment of top layer 11 in Fig. 1.As shown in Figure 3, top layer 11 comprises base portion 111 and the lug boss 112 that is arranged on base portion 111 and depressed part 113, the wherein tabular that is rectangle of base portion 111, lug boss 112 is outwardly formed by the upper surface of base portion 111 and is coniform, depressed part 113 is caved inward by the upper surface of base portion 111 and to be formed and in inverted cone-shaped, lug boss 112 and depressed part 113 be alternately evenly arrangement on base portion 111.
