Abstract

The invention discloses a novel artificial carbonized wood production method. The novel artificial carbonized wood production method includes the four steps of raw material processing, hot-pressing forming, carbonizing and surface processing. In the matching and stirring step in raw material processing, a mixture prepared from, by weight, pure fine pine powder, a sodium silicate solution, silica soil, nanometer titanium dioxide powder and sodium lignosulfonate according to the ratio of 6-8 to 2-4 to 0.3-0.5 to 0.1-0.3 to 0.05-0.07 is evenly stirred under the heated state so as to obtain a blank with the moisture content of 8-12%, the stirring speed is 200-250 r / min, and the stirring time is 15-20 min. Artificial carbonized wood has the beneficial effects of being good in flame-retardant performance and waterproof performance and environment-friendly, is suitable for various fields and is particularly suitable for the working environment where the artificial carbonized wood makes contact with water for a long time. Therefore, the artificial carbonized wood is a wood material having good application prospects.

Description

technical field [0001] The invention relates to a novel artificial carbonized wood production method, which belongs to the technical field of wood material production. Background technique [0002] Wood is an anisotropic porous material, which not only has the characteristics of sound insulation, heat insulation, good elasticity and high strength-to-weight ratio, but also has good tactile and visual effects. Therefore, wood is often used as sound insulation materials, building construction materials and wood products. With the rapid development of economic construction and the remarkable improvement of people's living standards, people's demand for wood is increasing day by day. Although wood is a renewable resource, the speed of supply is far slower than the speed of demand, which has led to an increasingly tense contradiction between wood supply and demand. In order to alleviate the tense situation of wood, people have adopted wood-based panel measures. [0003] Wood-ba...
