Abstract

The invention discloses a wood fiber powder preparation method which comprises the following steps: S1, crushing: selecting wood fibers, and crushing and stirring by adopting a crushing stirrer to obtain 30-150-mesh wood powder; s2, 30-150-mesh wood flour is placed in a reactor, a calcium hydroxide solvent is added, soaking is conducted for 60-360 min, the temperature is controlled to range from 20 DEG C to 40 DEG C, stirring is conducted through a stirring rod for 20-30 min so that the wood flour and the calcium hydroxide solvent can be evenly mixed, 3-5 parts of a stabilizer, 1-2 parts of a whitening agent and 0.5-1 part of an anti-ultraviolet agent are added, and filtering is conducted through a filter after reaction; s3, the solvent filtered in the S2 is placed in drying equipment for drying treatment, the drying time is 3-5 h, the wood fiber powder is dried till the water content is lower than 2%, an obtained product is placed in a mold, and the wood fiber powder is obtained. The preparation method of the wood fiber powder is simple in process, simple and convenient in operation process and low in material selection cost, and the prepared wood fibers are resistant to ultraviolet rays and high in toughness strength.

Description

technical field [0001] The invention relates to the technical field of preparation of wood fiber powder, in particular to a preparation method of wood fiber powder. Background technique [0002] Lignocellulosic fiber is an organic flocculent fibrous substance obtained from natural renewable wood through chemical treatment and mechanical processing. It is widely used in concrete mortar, gypsum products, wood pulp sponge, asphalt roads and other fields. Lignocellulosic biomass has many advantages such as large output, abundant sources, low price, renewable, biodegradable, and environmental friendliness, and is an ideal industrial raw material. With the decreasing storage of fossil raw materials such as coal and petroleum, the research on using green and renewable biomass raw materials to replace traditional fossil raw materials as raw materials for industrial production has attracted the attention of countries all over the world. Lignocellulosic fiber is a kind of biomass ene...
