Abstract

The invention belongs to the technical field of artificial plates, relates to a medium-density fiber plate, in particular to an anticorrosive and antibacterial medium-density fiber plate. The anticorrosive and antibacterial medium-density fiber plate is composed of 100% of completely-dried wood fibers, 8-12% of an adhesive, 0.25-1% of an antiseptic and antibiotic agent A, 0.25-0.5% of an antiseptic and antibiotic agent B and 1-2% of paraffin. The invention further discloses a process for manufacturing the anticorrosive and antibacterial medium-density fiber plate. The process comprises the steps of preparation of the antiseptic and antibiotic agents, material preparation, antiseptic treatment of poplar wood pieces, hot grinding, gluing, drying, hot pressing and cooling, classification andpackaging. The manufacturing process is simple, gingko wood and poplar wood serve as the wood materials, the gingko wood has a natural antiseptic effect, three substances including a boric acid, copper chelate and didecyl dimethyl ammonium chloride are selected to serve as the antiseptic and antibiotic agents, the application manners are different, the anticorrosive and antibacterial effects of the fiber plate are improved, and influences on the physical and mechanical properties of the plate are quite small.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels and relates to medium density fiberboards, in particular to an antiseptic and antibacterial medium density fiberboard and a manufacturing process thereof. Background technique [0002] my country is a big producer of wood-based panels. In 2015, China's fiberboard production has exceeded half of the world's total fiberboard production, reaching 56%. However, in terms of product variety, the outstanding problem is that there are many ordinary boards and few functional boards. This situation hinders the expansion of product application fields and weakens the market development ability. Many wood-based panel manufacturers compete to lower the price of ordinary panels, which reduces the economic benefits of the enterprise. [0003] Ordinary fiberboards are prone to decay, insects, and mildew, which not only reduces the service life of the fiberboards, but also putrefactive bacteria, mold, an...
