Problems solved by technology

Due to the use of wood powder in the WPC substrate, resources are wasted; glue is used for pressing during the processing, and formaldehyde is inevitably contained in the WPC composite board, causing environmental pollution; in addition, the glue coating process is required in the processing process, which increases The process steps also make it dif

Embodiment Construction

[0019] The present invention will be further explained below in conjunction with specific embodiments.

[0020] Such as Figure 1-3 , Example 1

[0021] A PVC composite board, comprising a substrate 1, the upper end of the substrate 1 is laminated with a noise-proof and moisture-proof layer 2, and the top of the noise-proof and moisture-proof layer 2 is pasted with a high-strength layer 3, and the upper surface of the high-strength layer 3 is laid There is a surface treatment layer 4 , a PVC foam board 5 is laminated on the lower surface of the substrate 1 , and a wear-resistant layer 6 is laminated on the lower surface of the PVC foam board 5 .

[0022] The noise-proof and moisture-proof layer 2 includes a fiberboard layer 21, a sound-absorbing cotton layer 22, a sound-insulating felt 23 and water-absorbing balls 24. The upper end of the inner cavity of the fiberboard layer 21 is pasted with a sound-absorbing cotton layer 22, and the lower end of the sound-absorbing surface ...

Abstract

The invention discloses a PVC (polyvinyl chloride) composite board. The PVC composite board comprises a base board. A noise-proof and moisture-proof layer is compressed at the upper end of the base board. A high-strength layer is adhered to the top end of the noise-proof and moisture-proof layer. A surface treatment layer is laid on the upper surface of the high-strength layer. A PVC foaming boardis compressed on the lower surface of the base board. A wearing layer is compressed on the lower surface of the PVC foaming board. The PVC composite board has the advantages that the PVC composite board is provided with the noise-proof and moisture-proof layer, a sound-absorbing cotton layer and a deadening felt in the noise-proof and moisture-proof layer have good sound absorption effect, and the effect is remarkable due to sound absorption by two layers of sound-absorbing materials; water-absorbing balls added into the deadening felt can absorb water to prevent moisture; the high-strength layer is arranged on the upper surface of the noise-proof and moisture-proof layer, so that the PVC composite board has high strength and harness, the strength is improved, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC composite board. Background technique [0002] PVC wood-plastic board is a board made of wood powder (or straw powder), thermoplastic polymer material PVC and processing aids, mixed evenly and then heated, extruded and formed by mold equipment. Comparing with the traditional pure wooden board, it has the advantages of no formaldehyde, benzene and other toxic substances, environmental protection and renewable, no radiation, strong decoration and reasonable price. Has a very broad market prospects. [0003] Existing composite panels, such as WPC composite panels, are mainly divided into three layers: surface layer, panel, printed color film, wear-resistant layer, and WPC base material. The processing method is divided into three steps: the first step is to glue the surface layer and the drawing paper into a whole; the second step is to extrude and shape the wood-...
