Through adopting above-mentioned technical scheme, can strengthen the syllable-dividing effect of this environment-friendly sponge through setting up honeycomb sponge layer, can strengthen the toughness of this environment-friendly sponge through EVA sponge inside lining.

Preferably, a plurality of hump grooves have all evenly been seted up with the inside of fire-retardant bottom to fire-retardant surface course, and the hump orientation of the interior hump groove of fire-retardant surface course and the inside hump groove of fire-retardant bottom is opposite, all pile up the liquid bag that has a plurality of splendid attire liquid fire extinguishing agents in the hump groove.

By adopting the technical scheme, when a fire disaster occurs, if the flame-retardant surface layer or the flame-retardant bottom layer cannot be flame-retardant, the liquid bag melts due to high temperature, so that the liquid fire extinguishing agent is released and permeates into the flame-retardant surface layer, the interlayer and the flame-retardant bottom layer, and the fire spread can be avoided.

Preferably, a plurality of liquid outlet holes are uniformly formed in the inner wall of the hump groove.

By adopting the technical scheme, the liquid outlet hole is beneficial to the liquid fire extinguishing agent to rapidly permeate into the flame-retardant surface layer and the flame-retardant bottom layer.

Preferably, the peripheral outer walls of the flame-retardant surface layer, the interlayer and the flame-retardant bottom layer are all stuck with a sponge edge with flame-retardant property together.

By adopting the technical scheme, the environment-friendly sponge has better structural stability.

To sum up, the application comprises the following beneficial technical effects:

1. according to the scheme, the sound insulation effect of the environment-friendly sponge can be enhanced by arranging the honeycomb sponge layer, and the toughness of the environment-friendly sponge can be enhanced by the EVA sponge lining;

2. the scheme can lead the liquid bag to melt due to high temperature after the flame-retardant surface layer or the flame-retardant bottom layer fails to be flame-retardant, so that the liquid extinguishing agent is released and permeates into the flame-retardant surface layer, the interlayer and the flame-retardant bottom layer, and the fire spread can be avoided.

Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses an environment-friendly sponge with multiple flame retardant layers. Referring to fig. 1 to 2, the environment-friendly sponge with multiple flame retardant layers comprises a flame retardant surface layer 1, an interlayer 2 and a flame retardant bottom layer 3, wherein the interlayer 2 and the flame retardant bottom layer 3 are sequentially arranged at the lower end of the flame retardant surface layer 1, the interlayer 2 and the flame retardant bottom layer 3 are all adhered with a sponge edge covering 10 with flame retardant property, and the environment-friendly sponge has better structural stability by arranging the sponge edge covering 10.

The interlayer 2 comprises a honeycomb sponge layer 20, an EVA sponge lining 21 and through holes 22, the honeycomb sponge layer 20 is adhered to the lower end of the flame-retardant surface layer 1 through flame-retardant adhesive, a mounting groove is formed in the middle of the honeycomb sponge layer 20, the EVA sponge lining 21 is arranged in the mounting groove, a plurality of through holes 22 are uniformly formed in the surface of the EVA sponge lining 21, the sound insulation effect of the environment-friendly sponge can be enhanced through the arrangement of the honeycomb sponge layer 20, and the toughness of the environment-friendly sponge can be enhanced through the EVA sponge lining 21.
