Embodiment 1
[0029] A thermal insulation and sound insulation composite board comprises a first fixed layer, a first adhesive layer, a sound insulation layer, a second adhesive layer, a straw plastic layer, a third adhesive layer and a second fixed layer.
[0030] The first fixed layer includes PVC transparent wear-resistant sheet, PVC patterned film, and PVC calendered sheet. The PVC transparent wear-resistant sheet, PVC patterned film and PVC calendered sheet are combined and embossed at 220 ° C. The UV oil coating on the transparent wear-resistant sheet is cured by ultraviolet rays, tempered and water-cooled and dried at 120°C to make the first fixed layer.
[0031] The first adhesive layer uses an environmentally friendly adhesive.
[0032] The sound-insulating layer is made of low-density polyethylene resin, cross-linking agent and foaming agent through high-temperature continuous foaming.
[0033] The second adhesive layer uses an environmentally friendly adhesive.

Embodiment 3
[0075] A thermal insulation and sound insulation composite board comprises a first fixed layer, a first adhesive layer, a sound insulation layer, a second adhesive layer, a straw plastic layer, a third adhesive layer and a second fixed layer.
[0076] The first fixed layer includes PVC transparent wear-resistant sheet, PVC patterned film, and PVC calendered sheet. The PVC transparent wear-resistant sheet, PVC patterned film and PVC calendered sheet are compositely embossed and dried at 230°C. The UV oil coating on the transparent wear-resistant sheet is cured by ultraviolet rays, tempered and water-cooled and dried at 130°C to make the first fixed layer.
[0077] The first adhesive layer uses an environmentally friendly adhesive.
[0078] The sound-insulating layer is made of low-density polyethylene resin, cross-linking agent and foaming agent through high-temperature continuous foaming.
[0079] The second adhesive layer uses an environmentally friendly adhesive.
