The soundproofing and light-shielding curtain comprises a first light-shielding layer 1, a first sound-insulating layer 2, a PVC layer 3, a second sound-insulating layer 4, and a second light-shielding layer 5 which are sequentially stacked and connected together. Among them, the first light-shielding layer 1 and the second light-shielding layer 5 are made of textile materials with light-shielding effect, so that both sides of the soundproofing and light-shielding curtain have a light-shielding effect, thereby improving the light-shielding performance and having a better light-shielding effect. The first sound-insulating layer 2 and the second sound-insulating layer 4 are made of textile materials with sound-absorbing effect, so that both sides of the soundproofing and light-shielding curtain have a sound-absorbing and noise-reducing effect, thereby having a better sound-insulating effect. The PVC layer is made of PVC material, which is polyvinyl chloride material, a common plastic material, which makes the soundproof blackout curtain have a certain hardness and can be bent to a certain extent, which not only retains the flexibility of part of the soundproof blackout curtain, but also increases the hardness and weight of the soundproof blackout curtain, making it not easily blown by the wind. The five-layer structure design increases the thickness and weight of the soundproof blackout curtain, and the PVC layer is blocked between the first sound insulation layer 2 and the second sound insulation layer 4, which can prevent cold wind, cold air, hot air, haze and other gaseous media from penetrating from one side of the soundproof blackout curtain to the other side of the soundproof blackout curtain, thereby having better windproof, warmth preservation and temperature locking effects. Therefore, the soundproof blackout curtain can reduce the impact of harsh environments such as external light, noise, cold wind, haze and other harsh environments on the indoor environment, and improve people's quality of life. In addition, since the first shading layer 1, the second shading layer 5, the first sound insulation layer 2 and the second sound insulation layer 4 made of textile materials are respectively arranged on both sides of the PVC layer, the PVC layer with a certain hardness is sandwiched between the soft textile materials on both sides, the outer surface of the soundproofing and light-shielding curtain is still soft to the touch, and the texture of the soundproofing and light-shielding curtain itself is guaranteed, which is highly practical.

[0027] In some specific embodiments, the PVC layer can also prevent the sound wave medium from penetrating from one side of the soundproof blackout curtain to the other side of the soundproof blackout curtain, and rebound the sound wave medium located on the side of the PVC layer close to the first blackout layer 1 to the first blackout layer 1 and the first sound insulation layer 2, and absorb and decompose the sound waves through the first sound insulation layer 2 to achieve the effect of reducing noise, or rebound the sound wave medium located on the side of the PVC layer close to the second blackout layer 5 to the second blackout layer 5 and the second sound insulation layer 4, and absorb and decompose the sound waves through the second sound insulation layer 4 to achieve the effect of reducing noise, thereby better preventing sound waves from penetrating from one side of the soundproof blackout curtain to the other side of the soundproof blackout curtain, thereby improving the sound insulation and noise reduction effect.
