Description

SOUND-ABSORBING PAINTTECHNICAL FIELD

[0001] The present disclosure generally relates to a sound- absorbing paint, and particularly, relates to a method for producing a sound-absorbing paint.BACKGROUND ART

[0002] In our bustling urban environments, the omnipresence of noise has become an undeniable challenge, affecting our daily lives and overall well-being. The cacophony of traffic, industrial activities, and everyday commotion can contribute to stress, sleep disturbances, and decreased productivity. Recognizing the detrimental impact of noise pollution on physical and mental health, there is an increasing awareness of crucial need to reduce environmental noise. Whether the noise be in residential areas, workplaces, or public spaces, mitigating adverse effects of noise has become a priority for creating healthier and more livable communities.

[0003] Various methods are employed to tackle the pervasive issue of noise in buildings and urban spaces. Architectural designs that incorporate sound- absorbing materials, double -pane windows, and acoustic panels have proven effective in reducing the transmission of external sounds. Additionally, advancements in technology have given rise to specialized soundproofing solutions such as noise barriers, insulation, and acoustic seals. These methods aim to create environments that foster tranquility and minimize the intrusion of unwanted sounds, providing a more conducive atmosphere for concentration, relaxation, and overall quality of life.

[0004] Accordingly, different methods have been used for reducing environmental noise in outdoor spaces, and similarly, various strategies can be implemented for reducing indoor noises. For example, Brandon D, et al. presented a patent on “Acoustical sound proofing material for architectural retrofit applications and methods for manufacturing same” (US20230003014A1). Brandon D has developed a laminated structure for retrofit building construction, featuring a panel with viscoelastic glue for improved acoustical soundproofing and efficient installation. This innovative solution, applicable to various surfaces such as existing walls, reduces transmitted noise significantly and streamlines both installation and finishing processes. Jun Lu et al. presented a patent on “Polymer interlayers having improved sound insulation properties” (US 10611126B2). Jun Lu has developed a novel polymer interlayer for glass panels,featuring a poly(vinyl acetal) resin with controlled residual hydroxyl and acetate content, and a specified plasticizer. This interlayer, designed with a glass transition temperature below 20°C, achieved soundproofing performance in a 2.3-mm glass panel configuration, with a transmission loss (TLw) exceeding 42 decibels and a coincident frequency transmission loss (TLc) surpassing 38 decibels at 20°C. However, the pursuit of noise reduction has its drawbacks and challenges. One notable concern is the financial investment required for implementing comprehensive soundproofing measures. High-quality soundproofing materials and professional installation can incur significant costs, making these solutions less accessible for individuals or communities with limited resources. Furthermore, some methods may alter aesthetics of buildings or spaces, potentially impacting their original designs. Balancing the need for noise reduction with considerations of cost and visual appeal becomes a complex endeavor in achieving effective and practical solutions.

[0005] There is, therefore, a need for an easy to use, cost-effective, anti-inflammatory, and light weight material for absorbing surrounding sounds. There is further a need for a simple method to produce the aforementioned material in a short period of time.SUMMARY OF THE DISCLOSURE
