Problems solved by technology

Since most of the wood-based panels need to be bonded with adhesives during the synthesis process, the adhesives will remain in the wood-based panels for a long time and produce volatile organic compounds (VOC), which are odors in the indoor air and pollution sources, thereby threatening people's health, and because the wood-based panels are prone to mildew when placed in a humid environment, it not only affects the service life of the panels, but also the mold is likely to have adverse effects on the human body

Abstract

The invention discloses a biomass charcoal-based preservative mould-proof environment-friendly artificial board. The artificial board is manufactured by the following steps of a, crushing biomass charcoal to obtain biomass charcoal powder; b, preparing a biomass charcoal soaking agent, wherein the biomass charcoal soaking agent includes the following components, by weight, 5-7 parts of preservative, 0.1-0.8 parts of mould inhibitor, 10-30 parts of water and 0.5-1.5 parts of dispersing agent; c, putting the biomass charcoal powder into the biomass charcoal soaking agent, performing ultrasonic dispersion for 30-60 minutes, and then, soaking the biomass charcoal for 12-24 h at 60-80 DEG C to obtain preservative mould-proof biomass charcoal; d, mixing the preservative mould-proof biomass charcoal with adhesive in the mass proportion of (10-50): 100, and performing stirring for 15-30 minutes at 3000-4000 r / min with a high speed stirrer to obtain preservative mould-proof biomass charcoal-based adhesive; and e, making the preservative mould-proof biomass charcoal-based adhesive used for manufacturing an artificial timber board. The artificial board not only can keep the preservative mould-proof effect and be prolonged in service life, but also can reduce release of volatile organic compounds (VOC) to reduce indoor air pollution and improve the living environment.

Description

technical field [0001] The invention relates to an anti-corrosion, mildew-proof and environment-friendly wood-based panel based on biomass charcoal, which belongs to the field of wood manufacturing. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. It mainly includes three major categories of products: plywood, particle (chip) board and fiberboard, which are widely used in the manufacture of furniture, desks, floors, walls and office supplies. Since most of the wood-based panels need to be bonded with adhesives during the synthesis process, the adhesives will remain in the wood-based panels for a long time and produce volatile organic compounds (VOC), which are odors in the indoor air And pollution sources, which threaten people's health, and because the wood-based panels ...
