[0028] The working principle of the above embodiment is:

[0029] (1) The first sound insulation layer 201 is a polyester fiber sound insulation cotton sound insulation layer. 100% polyester fiber is heat-pressed by high technology and is formed in the shape of cocoon cotton. The sound absorption coefficient reaches 0.94 in the noise range of 125-4000HZ. The first bonding layer 202 is an epoxy adhesive bonding layer. The presence of inherent polar hydroxyl groups and ether bonds in the epoxy resin molecular chain makes it have high adhesion to various substances. The epoxy resin has low shrinkage when curing and generates small internal stress, which also helps to improve the adhesion strength. The second sound insulation layer 203 is a non-woven fabric The sound insulation layer, the non-woven fabric has the characteristics of moisture-proof, breathable, flexible, thin, flame-retardant, non-toxic and odorless, low price, and recyclable.

The second bonding layer 204 is a phenolic resin bonding layer, which has good acid resistance, mechanical properties, and heat resistance. It is widely used in anti-corrosion engineering, adhesives, flame-retardant materials, grinding wheel manufacturing and other industries. The third sound insulation layer 205 is a sound insulation board sound insulation layer, and the sound insulation board is a plate that acts on the sound insulation effect.

[0030] (2) The fireproof layer 301 is an aluminum silicate fireproof layer. This material has the characteristics of light weight, high temperature resistance, thermal stability, low thermal conductivity, small heat capacity, good mechanical vibration resistance, heating, good thermal insulation performance, and good expansion. The aluminum silicate fiberboard, aluminum silicate fiber felt, aluminum silicate fiber felt, and aluminum silicate fiber felt products made through special treatment have the characteristics of low thermal conductivity, high temperature resistance, light weight, long service life, high tensile strength, good elasticity, and non-toxicity. It is a new material to replace asbestos and is widely used in thermal insulation in metallurgy, electricity, machinery, chemical industry and other industries. The waterproof layer 302 is a polyurethane waterproof coating, which has the characteristics of high strength, large elongation, good water resistance, etc., and has strong adaptability to deformation of the base layer. The polyurethane waterproof coating is a single-component environmentally friendly waterproof coating with liquid construction. It is based on imported polyurethane prepolymers, without additives such as tar and asphalt. It solidifies after contact with moisture in the air to form a solid, tough, seamless, integral anti-film on the surface of the base layer. The weather-resistant layer 303 is an amino resin weather-resistant layer. The paint film using amino resin as a cross-linking agent has excellent gloss, color retention, hardness, chemical resistance, water resistance and weather resistance. Therefore, coatings using amino resin as a cross-linking agent are widely used in industrial coatings such as automobiles, industrial and agricultural machinery, rigid furniture, household appliances and metal pre-coating. The wear-resistant layer 304 is a polyarylate wear-resistant layer with excellent transparency. When the thickness is 2mm, the light transmittance is above 87%, and it has good ultraviolet shielding properties.
