Abstract

The invention discloses a preparing method for an ultra-thin high-density fiberboard. The preparing method comprises the specific steps that (1) after a log material is digested and softened, nanometer antimonous oxide / PP composite fiber is added for hot grinding, heat treatment is carried out after drying, and pulverizing and accurate grinding are carried out to obtain wood powder fiber; (2) thewood powder fiber is placed in a glue blender, a glue material is sprayed onto the surface of the wood powder fiber, then montmorillonite / zirconium dioxide nano composite particles and a maleic anhydride grafted coupling reagent are added, and mixing and blending are carried out to obtain a material; and (3) the material is paved with a paving machine to form a plate blank, hot pressing treatmentis performed after pre-pressing is carried out, and the ultra-thin high-density fiberboard is obtained. According to the preparing method, the log material is adopted as the raw material of the fiberboard, the glue material and all functional auxiliary agents are sufficiently combined with the wood fiber through process machining, and therefore the preparation process is more efficient and environment-friendly; and the high-density fiberboard has the characteristics of being high in strength, high in density, ultra-thin, not easy to be deform, low in carbon, environment-friendly and durable.

Description

technical field [0001] The invention belongs to the technical field of fiberboard processing, and in particular relates to a method for manufacturing an ultra-thin high-density fiberboard. Background technique [0002] In recent years, my country's high-density fiberboard industry has developed very rapidly. Due to the great dependence of MDF enterprises on wood raw materials, the shortage of wood raw materials has seriously affected the production of fiberboards, so it has been gradually replaced by high-density fiberboards. [0003] High-density fiberboard is a board made of wood fiber or other plant fibers, applied with urea-formaldehyde resin, or other synthetic resins under heat and pressure. With its excellent physical properties, high-density fiberboard is compatible with all the advantages of MDF. It is widely used in indoor and outdoor decoration, office, high-end furniture, audio, and interior decoration of luxury cars. It can also be used as an antistatic floor fo...
