Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, in the embodiment, the multilayer sound-absorbing cotton for the lower portion of the right back door of the automobile includes an anti-collision layer 1, a waterproof layer 2 is fixedly connected to the lower surface of the anti-collision layer 1, a sound-absorbing cotton body 3 is fixedly connected to the lower surface of the waterproof layer 2, a flame-retardant layer 4 is fixedly connected to the lower surface of the sound-absorbing cotton body 3, and a moisture-proof layer 5 is fixedly connected to the lower surface of the flame-retardant layer 4.

The waterproof layer 2 is a plastic plate layer, and the thickness of the waterproof layer 2 is zero six centimeters.

The anticollision layer 1 is an aluminum alloy plate layer, and the thickness of the anticollision layer 1 is four centimeters at zero.

The flame-retardant layer 4 is a flame-retardant density board layer, and the thickness of the flame-retardant layer 4 is zero point five centimeters.

The moisture-proof layer 5 is an anti-doublet board layer, and the thickness of the moisture-proof layer 5 is two centimeters at zero point.

The lower surface of the anti-collision layer 1 is bonded with the upper surface of the waterproof bin 2 through anaerobic glue.

The working principle of the above embodiment is as follows:

(1) through setting up anticollision layer 1, anticollision layer 1 is the aluminum alloy plate layer, mainly makes by the aluminum alloy plate, and its material has good anti-stamping performance, and has anticorrosion and rust-resistant ability, through setting up anticollision layer 1 as outer for inhale the sound cotton and possess the anti-collision ability.

(2) Through setting up waterproof layer 2, waterproof layer 2 is the plastic sheet layer, mainly is made by the plastic slab, and the plastic slab is exactly to make panel with plastics, and plastics are synthetic macromolecular compound, can freely change the physique pattern, and its surface density reaches highly, and the most obvious advantage is waterproof to the plastic sheet layer is as waterproof layer 2's preparation material, can make to inhale the sound cotton and have waterproof ability.

(3) Through setting up fire-retardant layer 4, fire-retardant layer 4 is fire-retardant density board layer, mainly make by fire-retardant density board, fire-retardant density board is with wood fiber or other vegetable fibre as the raw materials, apply urea-formaldehyde resin or other adhesive that are suitable for, spout the gluey section, just like the gluey section, add the fire retardant into the panel of making density at 500 ~ 880kg/m3 scope in the production line, fire-retardant density board has good physical mechanical properties and processing property, can make the panel of different thickness, fire-retardant density board has splendid fire behavior, after receiving the fire source, can in time extinguish the fire source, the burning phenomenon can not appear, through setting up fire-retardant layer 4, make the flame retardant ability of inhaling the sound cotton promoted by a wide margin.

(4) By arranging the moisture-proof layer 5, the moisture-proof layer 5 is a compact board layer and is mainly made of a compact board, the compact board is a high-strength flat board made of wood fibers and thermosetting resin through high-pressure polymerization, and an integrated coloring resin decorative surface layer is formed by adopting a special technology, so that the compact board has extremely high weather resistance, and the appearance and the characteristics of the compact board cannot be influenced by rapid temperature change no matter sunlight, rain and wind erosion or moisture on the surface of the compact board; the anti-doubling plate has higher elastic modulus, tensile strength and bending strength, so that the anti-doubling plate has high impact resistance; the high-density core material gives the anti-double board high anchoring piece pulling strength, and the characteristic is particularly important for the board adopting a bolt or plug-in mounting mode; the anti-doubling plates have excellent fire resistance and do not melt, drip or explode, and European related organizations classify the anti-doubling plates into the highest fire-proof grade of organic materials and do not release toxic and corrosive gases; the anti-doubling plate can be kept stable for a long time, has self-cleaning property, is compact in material, does not adhere dust, and is easy to clean.
