Description
Technical Field
The invention relates to the technical field of building parts, in particular to a building window screen with a noise reduction function and a manufacturing method thereof.
Background
Building ventilation is a necessary function for ensuring the removal of indoor pollutants from a building, ensuring the thermal comfort of indoor personnel, and meeting the requirements of indoor personnel for fresh air. The civil buildings are necessary for preventing external noise interference and the industrial buildings are necessary for ensuring the comfort of the internal and external environments of the buildings to avoid noise leakage.
The institute of housing and urban and rural construction department in 2 months 2014 publishes and implements 'building ventilation effect test and evaluation standards', and provides standard basis for testing and evaluating the indoor ventilation effect of buildings. GB50352-2019 unified Standard for civil building design from 10/1 in 2019 passes through the Ministry of housing and construction to be approved as a national standard and starts to be implemented, wherein chapter 7 makes principle regulations on building ventilation and building sound insulation and noise reduction in 7.2 ventilation environments and 7.4 sound environments respectively.
However, since the flow of air through the ventilation window necessarily generates sound, noise from other sound sources can also propagate through the ventilation window and other channels, and ventilation and noise reduction form a natural contradiction. Even the above-mentioned national standards do not effectively and directly solve the contradiction.
An example is as follows: a residence located alongside a town road. Road traffic noise has serious adverse effect on the interior acoustic environment of a house, and a closed laminated glass soundproof window or a hollow glass window can effectively isolate noise, but ventilation is required because the house has a sanitary environment requirement, and once the window is opened, the soundproof effect can be completely failed.
Example two is as follows: industrial plants with noise sources inside. Most industrial factory buildings can cause noise pollution to the inside and the surrounding environment of the factory building simultaneously, and most industrial factory buildings have ventilation requirements, but the general ventilation windows can not avoid noise leakage.
Example three: a sound insulation curtain. The sound insulation curtain which appears in recent years can reduce the noise by 8-12 dB, but the use scene of the sound insulation curtain is limited, for example, the sound insulation curtain can be used for the first example, but can not be used for the second example; meanwhile, the sound insulation curtain requires four sides to be sealed in the using process, and the ventilation requirement of the first example is very unfavorable.
In conclusion, the existing building parts such as doors, windows, curtains and screens have the problem that ventilation and noise reduction are difficult to be realized simultaneously.

Secondly, by adopting an electrostatic flocking technology, short fiber fuzz is fully distributed on the surface of the diamond mesh window screen, and a gap structure is formed by the short fiber fuzz, so that the sound absorption and noise reduction effects are further enhanced.
The cold pressing method for changing the appearance of the diamond mesh and the electrostatic flocking method can be combined for use or can be respectively and independently used.
In the above method, first, the shape and size of the mold unit need to be determined, and the mold is deeply designed and opened. And then pressing the diamond mesh 12 into a designed shape by using a cold pressing production line and a die produced in the previous step, specifically, placing the diamond mesh 12 between a first die 7 and a second die 8, and pressing and forming the diamond mesh 12 by using the two layers of dies, as shown in fig. 5, wherein the arrow direction in the figure is the pressing direction, the first die 7 is provided with a folded plate concave structure, the second die 8 is provided with a folded plate convex structure, and the perforation on the diamond plate 12 is only partially illustrated in the figure. Then, the electrostatic flocking production line is used for flocking the pressed diamond mesh on one side or two sides, as shown in fig. 6, wherein the arrow direction is the flocking direction. The window screen processed by the steps can be directly sold as a finished product.
Example 5
As shown in fig. 7, this embodiment proposes a noise reduction screen, in which the architectural window screen of example 4 is incorporated into a commercially available window frame profile 10 of acceptable quality, to constitute a noise reduction screen. The noise reduction screen window can be processed and supplied in a factory manner, and can also be manufactured by other small-scale processing workshops according to related quality standards. Reference numeral 9 in the figure denotes a lighting window 9.
Example 6
In addition, after the residual sound waves passing through the building window screen perforation are blocked by the curtain 11 and the like, multiple reflections are formed between the curtain 11 and the other side of the window screen again, and the residual sound waves are continuously absorbed and lost.
Therefore, this embodiment provides a noise reduction structure, as shown in fig. 8 and 9, on the basis of the noise reduction screen window of embodiment 5, a curtain 11 is further added, and the noise reduction screen window and the curtain 11 are used in cooperation, so as to further improve the noise reduction effect. Reference numeral 9 in the figure denotes a lighting window 9.
