Abstract

The invention discloses a method for preparing an insect bite-prevention antibacterial fiber board, which relates to the field of the fiber board. The method comprises the following steps: (1) performing pulp refining to obtain plant fiber pulp; (2) preparing pesticidal antibacterial liquid; (3) mixing the pulp and a residual material; (4) preparing a slab; (5) drying the slab; (6) preparing silica sol; (7) dipping the slab with the silica sol; and (8) preparing the insect bite-prevention antibacterial fiber board. The fiber board has the functions of anti-mold sterilization and anti-insect, has a stable structure, has good flame retardancy and corrosion resistance, and is easy to process.

Description

technical field [0001] The invention relates to the field of fiberboards, in particular to a method for preparing moth-proof and antibacterial fiberboards. Background technique [0002] Fiberboard is a kind of man-made board made by mechanically separating and chemically treating wood or plant fibers, adding adhesives and waterproofing agents, etc., and then molding under high temperature and high pressure. It is an ideal man-made board for making furniture. The structure of medium and high-density fiberboard is more uniform than that of natural wood, and it also avoids problems such as decay and insects. At the same time, it has small expansion and contraction and is easy to process. [0003] Patent CN1107132C discloses a new method for manufacturing a fiberboard from plant fibers, preferably flax and hemp. The fibers are pretreated and shortened, and then separated to produce a fiber mass consisting of individual fibers within the desired length range. Fiberboards are th...
