Abstract

The invention discloses a preparation method of a mildew-proof shaving board. The preparation method comprises the following steps of carrying out heat treatment on wood shavings, sending the wood shavings into a stirrer, spraying a mixture of a golden cypress extracting solution, an andrographis paniculata extracting solution, a calyx seu fructus physalis extracting solution and a fructus cnidiiextracting solution while stirring the wood shavings, drying the wood shavings until the water content is 3.4 wt%-5.5 wt%, and gluing the wood shavings, wherein the raw material of a used adhesive comprises soybean glue, phenolic resin, PVAc latex, melamine glyoxal resin, didodecyl dimethyl ammonium chloride, a nano zirconium phosphate silver-loaded antibacterial agent, a litsea cubeba extract, amulberry leaf extract, a Biebersteinia heterostemon extract, dried orange peel essential oil, sepiolite, nano cellulose, hexamethylenetetramine and diphenylmethane diisocyanate; and laying the pretreated wood shavings subjected to gluing into a plate blank, and carrying out pre-pressing, hot-pressing, cooling, edge cutting and sanding to obtain the mildew-proof shaving board. The preparation method of the mildew-proof shaving board is simple in process, and the obtained shaving board is excellent in antibacterial and mildew-proof performance, good in water resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of boards, in particular to a method for preparing mildew-proof particle boards. Background technique [0002] Particleboard is a kind of man-made board made of hot-pressed wood chips or non-wood plant chips using adhesives at a certain temperature and pressure, also known as particle board. It is relatively uniform and has good processing performance. It can be processed into panels of different widths according to needs, and furniture of different specifications and styles can be made. Compared with other board types, particleboard production has low energy consumption, low cost, low quality requirements for wood raw materials, and good physical and mechanical properties. It has been widely used in furniture, decoration, building materials, vehicles, packaging, and ships. and other industries. However, due to the nature of the wood and the properties of the adhesive used, the particleboard processed from...
