Antibacterial wood-like board for indoor decoration and preparation method

Abstract

The invention provides an antibacterial wood-like board for indoor decoration and a preparation method. The antibacterial wood-like board is prepared from an antibacterial wood-like layer formed on the surface of a polypropylene substrate through surface co-extrusion, the polypropylene substrate is prepared from polypropylene matrix resin, a coupling agent, a bulking agent and an antioxidant through mixing and extrusion, and the antibacterial wood-like layer is prepared as follows: coating natural clinoptilolite with graphene oxide, adding the coated natural clinoptilolite and hydrazine hydrate to a silver salt solution to react to prepare antibacterial filler, then, mixing the antibacterial filler with ASA weather-resistant resin and wood-like pigment and performing extrusion to prepare the antibacterial wood-like layer. In the antibacterial wood-like board, nano-silver and graphene in the antibacterial filler are closely combined and cannot fall off easily, the antibacterial effect is more lasting, the obtained wood-like plate is endowed with good antibacterial and sterilization characteristics, meanwhile, large granules are realized through two times of fixed loading, uniform dispersion is facilitated, and production and processing are easy.

Description

technical field [0001] The invention relates to the technical field of wood-like materials, in particular to an antibacterial wood-like board for interior decoration and a preparation method thereof. Background technique [0002] In recent years, due to the excessive exploitation and utilization of forest resources, the ecological environment has deteriorated and soil erosion has been serious. However, with the gradual improvement of people's living standards, people's demand for wood has also increased. Therefore, the demand for imitation wood materials is gradually increasing. is increasing. Decorative materials are the material basis of architectural decoration engineering, and they are the actual effect of decoration engineering and the concrete display of the color, texture and texture of decorative materials. As an important part of modern home decoration, interior wall decoration materials are used in the overall home decoration. The largest proportion. [0003] Exi...

Problems solved by technology

[0007] In view of the poor antibacterial performance of the current imitation wood materials, and the antibacterial nano-silver and graphene that can be added to the modified wood-like materials cannot be tightly combined, it is easy to fall off, affecting the service life and antibacterial effect and other technical problems, the present invention proposes a Antibacterial imitation wood board for interior decoration and preparation method thereof, thereby endowing the imitation wood board with good antibacterial and bactericidal properties
