The invention provides a sound-absorbing flame-retardant rubber plate and an underwater sound-absorbing flame-retardant structure, the sound-absorbing flame-retardant rubber plate comprises a sound-absorbing main body layer and a flame-retardant material layer laid on the surface of one side of the sound-absorbing main body layer, and the sound-absorbing main body layer and the flame-retardant material layer are integrally formed through heating and mold pressing by a press vulcanizer; and the flame-retardant material layer is a chloroprene rubber adhesive with sound wave penetration performance and good flame-retardant performance. The flame-retardant material layer is laid on the surface of the sound absorption main body layer, the sound absorption main body layer and the flame-retardant material layer are integrally formed in a mold of a press vulcanizer in a hot press mode, and in the forming process, the sound absorption main body layer and the flame-retardant material layer can be mutually permeated and bonded into a whole at the junction. The flame-retardant material layer formed by the scheme does not fall off along with thermal expansion and cold contraction and repeated expansion and contraction of the non-metallic material.
本发明提供了一种吸声阻燃橡胶板及水下吸声阻燃结构,包括吸声主体层和铺设于吸声主体层一侧表面的阻燃材料层,所述吸声主体层和阻燃材料层经平板硫化机加温模压一体成型,所述阻燃材料层为具有声波穿透性能且阻燃性能好的氯丁胶。本发明通过在吸声主体层表面铺设有一层阻燃材料层,在平板硫化机一个模具内热压成型为一体,在成型过程中,吸声主体层与阻燃材料层交界处会相互渗透,粘合为一体,相比传统的在吸声主体层表面进行喷涂方式,本方案形成的阻燃材料层不会随着非金属材料热胀冷缩,反复伸缩而脱落。
