Embodiment Construction
[0012] The present invention will be further described below in conjunction with embodiment.
[0013] The shock-absorbing and sound-absorbing wood-plastic composite PVC board includes 5 layers of composite structure, which are shock-absorbing and sound-absorbing layer, resin adhesive layer, wood-plastic foam board layer, resin adhesive layer, and PVC composite layer from bottom to top. The PVC composite layer is a four-layer composite structure, which are PVC calendered sheet, patterned film, PVC transparent wear-resistant sheet, and UV coating from bottom to top; the wood-plastic foam board layer is selected with a purity greater than 99%wt and a particle size of 300-520nm Ultrafine calcium oxide powder is used as an adsorbent, and an ultra-high molecular weight silicone processing aid that does not contain an organic carrier is added to the wood-plastic foam board layer; the shock-absorbing and sound-absorbing layer is a cork pad (in other embodiments, the shock-absorbing and...

Abstract
The invention discloses a damping and noise-reducing wood-plastic composite PVC board. The damping and noise-reducing wood-plastic composite PVC board comprises a five-layer compound structure which separately comprises a damping and noise-reducing layer, a resin glue bonding layer, a wood-plastic foaming plate layer, a resin glue bonding layer and a PVC compound layer from bottom to top, whereinthe PVC compound layer is of a four-layer compound structure, and comprises a PVC calendered sheet, a patterned film, a PVC transparent wear-resisting sheet and a UV coating from bottom to top; for the wood-plastic foaming plate layer, ultrafine calcium oxide powder with purity greater than 99% by weight and a grain size of 300-520 nm is selected as an adsorber; the board is further improved in that an ultrahigh-molecular-weight silicone processing aid not containing an organic carrier is added into the wood-plastic foaming board layer; and the damping and noise-reducing layer is one of a softwood cushion, an EVA foamed cushion and a PVC foamed cushion. During preparation, wood powder and resin matrix are good in compatibility, so that the damping and noise-reducing effect and the noise-isolating effect are good.
Description
technical field [0001] The invention relates to a polymer composite material, in particular to a wood-plastic composite PVC board. Background technique [0002] Wood-plastic composite PVC board is a kind of composite material composed of wood powder and resin matrix, which can realize the large-scale utilization of wood powder. However, wood powder and resin matrix are difficult to be compatible. On the other hand, with the development of science and technology and the improvement of people's living standards, "health" and "safety" have become the two most concerned issues of contemporary people. Wood-plastic composite materials have poor shock absorption and noise reduction and sound insulation effects, which cannot meet consumers' health and environmental protection needs. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a wood-plastic composite PVC board that can significantly improve the compatibility betwe...
