Embodiment 1
[0051] A composite floor, with reference to figure 1 , which includes a wear-resistant layer 1, a PVC pattern fabric layer 2, a substrate layer 3, a balance layer 4 and a sound-absorbing layer 5 arranged in sequence. Wherein, the wear-resistant layer 1 is a melamine wear-resistant paper layer; the base material layer 3 is an SPC base material layer; the balance layer 4 is a balance paper layer; the mute layer 5 is a cork layer.
[0052] refer to figure 2 The PVC pattern fabric layer 2 includes a body layer 23 and a pattern layer 22 formed by printing water-based PVC ink on the front side of the body layer 23 . The front and back sides of the PVC pattern fabric layer 2 are all provided with an adhesive layer 21 . The adhesive layer 21 is formed by coating the glue configured according to the following ratio:
[0053] Chlorinated rubber 5g
[0054] Perchlorethylene resin 10g
[0055] Modified low molecular weight polyamide hot melt adhesive 5g
[0056] Highly Branched Tal...
Embodiment 2
[0066] A composite floor, with reference to figure 1 , which includes a wear-resistant layer 1, a PVC pattern fabric layer 2, a substrate layer 3, a balance layer 4 and a sound-absorbing layer 5 arranged in sequence. Wherein, the wear-resistant layer 1 is a melamine wear-resistant paper layer; the base material layer 3 is an SPC base material layer; the balance layer 4 is a melamine wear-resistant paper layer; the quiet layer 5 is an EVA foam layer.
[0067] refer to figure 2 The PVC pattern fabric layer 2 includes a body layer 23 and a pattern layer 22 formed by printing water-based PVC ink on the front side of the body layer 23 . The front and back sides of the PVC pattern fabric layer 2 are all provided with an adhesive layer 21 . The adhesive layer 21 is formed by coating the glue configured according to the following ratio:
[0068] Chlorinated rubber 2g
[0069] perchlorethylene resin 8g
[0070] Modified low molecular weight polyamide hot melt adhesive 2g
[0071...
Embodiment 3
[0081] A composite floor, with reference to figure 1 , which includes a wear-resistant layer 1, a PVC pattern fabric layer 2, a substrate layer 3, a balance layer 4 and a sound-absorbing layer 5 arranged in sequence. Among them, the wear-resistant layer 1 is a melamine wear-resistant paper layer; the substrate layer 3 is a WPC substrate layer; the balance layer 4 is composed of PVC film and melamine balance paper, and the PVC film is composited on the substrate layer 3; the mute layer 5 IXPE foam layer.
[0082] refer to figure 2 The PVC pattern fabric layer 2 includes a body layer 23 and a pattern layer 22 formed by printing oily PVC ink on the front side of the body layer 23 . The front and back sides of the PVC pattern fabric layer 2 are all provided with an adhesive layer 21 . The adhesive layer 21 is formed by coating the glue configured according to the following ratio:
[0083] Chlorinated rubber 3g
[0084] Perchlorethylene resin 10g
[0085] Modified low molecu...
