Abstract

The invention discloses a fibrilia-based indoor antibacterial wood-plastic composite wallboard. Main raw materials of the composite wallboard comprise a matrix composed of fibrilia, a filler composedof a polymer and a proper amount of an additive. According to the fibrilia-based indoor antibacterial wood-plastic composite wallboard, fibrilia is used as a base body, the natural fibrilia can achieve a good antibacterial effect, other antibacterial additives do not need to be added, the service life of the wallboard is guaranteed, the manufacturing process is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wallboards, in particular to a hemp fiber-based indoor antibacterial wood-plastic composite wallboard. Background technique [0002] With the continuous exploitation of resources and the excessive felling of trees, the available wood is getting less and less. At the same time, people are paying more and more attention to environmental protection. Therefore, people use wood-plastic materials to replace traditional wood materials, such as wood wall panels. However, the currently used wood-plastic wall panels cannot have antibacterial effects due to the limitations of the materials used, and such wall panels have a short service life; some composite wall panels will add some additives to achieve antibacterial effects in order to inhibit bacteria. The board is not only expensive to manufacture, but also has a cumbersome process. Contents of the invention [0003] The purpose of the present invention is to ...
