Abstract

The invention discloses an environment-friendly artificial carbonized wood production method. The method includes four steps of raw material treatment, hot press molding, carbonization treatment and surface treatment. In raw material treatment, a mixture composed of pure fine pine powder, a sodium silicate solution, silica sol, nanometer titania powder, sodium lignin sulfonate and talcum powder according to the weight part ratio of 5-8:2-5:0.4-0.6:0.1-0.3:0.04-0.08:0.02-0.04 is stirred evenly in a heated state, so that a blank material with the moisture content ranging from 8% to 12% is obtained, the stirring speed ranges from 230 r/min to 250 r/min, and stirring time ranges from 15 min to 25 min. Artificial carbonized wood produced through the method has the characteristics of being good in flame resistance, good in waterproof performance, environmentally friendly, suitable for multiple fields and particularly suitable for the working environment making contact with water for a long time.

Description

technical field [0001] The invention relates to an environment-friendly artificial carbonized wood production method, which belongs to the technical field of wood material manufacturing. 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...
