The technical solution of the utility model is：A kind of sound-absorption and heat-insulation cotton, including cotton body, if forming dry-pressing on cotton body
Contact, described cotton body is sequentially provided with fungi-proofing layer, radiation protective layer, thermal insulation layer, sound absorbing layer and press-stretched layer from top to bottom, described
Fungi-proofing layer includes bamboo charcoal adsorption layer, above bamboo charcoal adsorption layer, is below pasted with first respectively by hot pressing complex method
Nonwoven layer, the second nonwoven layer, described radiation protective layer is formed by stainless steel fiber layer and the pressing of aluminum fibrous layer, described
The second nonwoven layer below stainless steel fiber layer is compounded with by hot pressing, below described aluminum fibrous layer hot pressing answer
Conjunction has the 3rd nonwoven layer, and described thermal insulation layer is aluminosilicate fiber cotton layer, below the 3rd nonwoven layer hot pressing be compounded with silicon
Sour aluminum fiber cotton layer, below aluminosilicate fiber cotton layer hot pressing be compounded with the 4th nonwoven layer, described sound absorbing layer is melt-blown cotton
Layer, upper and lower glass layer is pasted with respectively on the upper and lower surface of melt-blown cotton layer, glass is pasted with below the 4th nonwoven layer
Glass fibrous layer, described press-stretched layer, described press-stretched are provided with by the 5th nonwoven layer below described lower glass layer
Layer includes press-stretched piece, and four edges of press-stretched piece are respectively equipped with fin.
Further, described thermal insulation layer is zirconium cellucotton layer.
Further, described melt-blown cotton layer includes polypropylene short fiber (PP) layer and the hot pressing under polypropylene short fiber (PP) layer
Compound polyester staple fiber (PET) layer.
Further, described press-stretched piece is pasted onto the lower surface of melt-blown cotton layer.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, the fungi-proofing layer of setting, preventing
Radiating layer, thermal insulation layer, sound absorbing layer and press-stretched layer, strengthen its reliable and stable block position, raising service life, improve sound insulation effect
Fruit, prevent its mouldy and moth, it is more convenient.

Embodiment
As shown in figure 1, the technical solution of the utility model is a kind of sound-absorption and heat-insulation cotton, including cotton body 1, on cotton body
Some crimping points 2 are formed, crimping scoring roller by ultrasonic wave on cotton body 1 crimps to form some crimping points 2, and shuts out flower
Line so that every layer of integrated positioning of cotton body 1 is reliable and stable, will not aliquation come off；
Described cotton body 1 is sequentially provided with fungi-proofing layer, radiation protective layer 6, thermal insulation layer 8, sound absorbing layer 10 and press-stretched from top to bottom
Layer；
Described fungi-proofing layer includes bamboo charcoal adsorption layer 3, above bamboo charcoal adsorption layer 3, passes through hot pressing composite square below
Formula is pasted with the first nonwoven layer 4, the second nonwoven layer 5 respectively, and the setting of bamboo charcoal adsorption layer 3 has suction-operated, can be right
First nonwoven layer 4 is protected, and prevents its mouldy and moth, and it is mouldy to prevent that cotton body 1 from producing, has higher stability,
The bamboo charcoal adsorption layer 3 of honeycomb can further improve erasure effect simultaneously,
Described radiation protective layer 6 is formed by stainless steel fiber layer and the pressing of aluminum fibrous layer, the second described non-woven fabrics
Stainless steel fiber layer is compounded with by hot pressing below layer 5, below described aluminum fibrous layer hot pressing be compounded with the 3rd nothing
