Abstract

The invention discloses a production method for high-strength thermally-modified rubber wood floor. The production method comprises the following steps: sawing rubber logs into laminated timbers or blank; putting the laminated timbers or blank into a vacuum treatment tank, and carrying out impregnation in vacuum by taking boric acid and an acetic acid aqueous solution as a treating fluid; drying the laminated timbers or blank subjected to impregnation in vacuum until moisture content is 25-35%; stacking and putting the pre-dried laminated timbers or blank into carbonization treatment equipment, taking a 0.2-0.3% mycose solution as a superheated steam heat-transfer medium and a protective gas, increasing the temperature to 60-80 DEG C at a rate of 5-8 DEG C / min, and preserving the temperature for 2-3 hours, then heating the timers to 220-240 DEG C at a rate of 5-8 DEG C / min and preserving the temperature for 1-1.5 hours, stopping heating and cooling, and spraying steam to regulate humidity; and finally, preparing the wood floor. According to the production method, the process is environmentally-friendly, and hazardous substances such as resin and the like are not contained; and the obtained rubber wood floor is high in strength, good in termite resistance, stable in dimension and durable.

Description

technical field [0001] The invention relates to a production process of a modified high-strength rubber wood floor, which belongs to the field of wood processing. Background technique [0002] Heat Modified Wood (Heat Modified Wood), also commonly known as deep carbonized wood in my country. It refers to the use of 160-230 degrees (commonly used 180-215 degrees) to heat the wood to improve the quality of the wood and reduce the moisture absorption and water absorption of the wood. It improves dimensional stability, biological decay resistance and weather resistance, thus making a wood product with excellent performance, beautiful color and environmental friendliness. Through the control of different media and different temperatures in the production process, curing, coloring, surface burning and other treatments, various products with slightly different properties can be obtained. Thermally modified wood is a real green product, although it has anti-corrosion and insect-proof...
