| description | The invention discloses a three-layer co-extrusion mute drain pipe and a preparation method and an application thereof. The components of a three-layer structure are improved, and a sound absorption viscoelastic inorganic material and a defoaming agent are added to a middle core layer, so that sound waves generated in the water flow process can be absorbed, sound is prevented from being spread outwards, and the good noise reduction and mute effects are achieved; according to the present invention, the internal molecular structure of the pipe is improved, the compactness and the density of the pipe are improved, the softening temperature of the pipe is significantly increased, the pipe is not easily aged under the long-term sunlight exposure, the service life is long, the modulus is high, the pipe has high ring stiffness and strong acid-base corrosion resistance, the acid resistance can achieve pH2, the alkali resistance can achieve pH12, and the liquid with the pH2-pH12 can be arbitrarily discharged.
