Problems solved by technology

[0002] At present, there are many kinds of PVC sheets, but most of them are either not wear-resistant and compressive, or the density is too high and too heavy, so it is inconvenient to carry.
In addition, the existing boards have high formaldehyde content. After the interior decoration is completed, it often needs to be placed for about 3-6 months before moving in.

Abstract

The invention discloses a PVC composite plate. The PVC composite plate is of a composite layer structure and comprises outer panel layers and an inner panel layer arranged between the outer panel layers, wherein the outer panel layers contain the following components in parts by weight: 47-58 parts of PVC resin, 32-38 parts of nano-light calcium carbonate, 5-7 parts of a calcium-zinc stabilizer, 0.98-1.42 parts of an inner lubricant, 1-1.5 parts of a PVC foaming modifier, 0.18-0.22 part of ACR-401 and 1-1.5 parts of titanium dioxide. The invention further discloses a preparation method of thePVC composite plate. According to the PVC composite plate provided by the invention, the density of the PVC composite plate is reduced, the integral strength of a product is enhanced, and light and pressure-proof effects are achieved.

Description

technical field [0001] The invention belongs to a PVC board, in particular to a PVC composite board and a preparation method thereof. Background technique [0002] At present, there are many kinds of PVC boards, but most of them are either not good enough in wear resistance and compressive strength, or they are too dense and heavy, so they are inconvenient to carry. In addition, the existing boards have high formaldehyde content, and after the interior decoration is completed, it often needs to be placed for about 3-6 months before moving in. [0003] The following patent documents are now retrieved, which do not have technical implications for the present invention: [0004] Patent 1: [0005] Application number 201310618375.X, applicant Qingdao Kechuang Plastic Machinery Co., Ltd., the patent relates to a PVC composite board, the composite board has a three-layer structure, the middle layer is wood, and the other two layers are PVC boards. The surface in contact with th...
