The invention discloses a damping and noise-eliminating material, a noise-eliminating tile, a preparation method of the damping and noise-eliminating material and application of the damping and noise-eliminating tile to noise elimination and damping of a submarine. The damping and silencing material is obtained by blending, crosslinking and foaming raw materials including carboxyl-terminated polyamide elastomer and epoxy resin, in the formula, PAx is a polyamide block, PE is a polyether block, and R is an alkylene chain or phenyl of C3-C9; x is the polymerization degree of the polyamide block; and n is the polymerization degree of the polyamide elastomer. The shock-absorbing and noise-eliminating material can be adhered to the surface of a metal material with a structural epoxy resin adhesive, and the shock-absorbing and noise-eliminating material is high in shear strength, high in noise-eliminating and noise-reducing rate and excellent in comprehensive physical performance, and can be widely applied to noise elimination and shock absorption of submarines.
本发明公开了一种减震消声材料、消声瓦及制备方法和在潜水艇消声减震中的应用。减震消声材料由包含以下端羧基聚酰胺弹性体与环氧树脂在内的原料通过共混、交联和发泡得到;#imgabs0#其中,PAx为聚酰胺嵌段,PE为聚醚嵌段,R为C3~C9的亚烷基链或苯基;x为聚酰胺嵌段的聚合度;n为聚酰胺类弹性体的聚合度。该减震消声材料可与结构型环氧树脂胶粘剂粘接至金属材料表面,且减震消声材料剪切强度高、消声降噪率高、综合物理性能优良,可以广泛应用于潜水艇消声减震。
