Description
Technical field
The present invention relates to a kind of particieboard with Anticorrosive Character, and relate to the production method of this anticorrosion particieboard.
Background technology
China's timber industry is in by utilizing wildwood timber to be main to utilizing artificial forest wood to be that in main transition process, artificial forest fast-growing small wood will be the wood raw material that China is main from now on.And artificial forest fast growing wood apt to rot, infested, go mouldy; therefore wood protection will play the effect in prolonging wood life-span; play reduce timber and cause due to rotten, infested degradation, degradation, the discarded and waste that causes, the quality improving Wood products, the effect increasing Wood products function can also be played.Reduce loss and waste that timber causes because of the reason such as rotten; extend the service life of woodwork; alleviate related industries (comprising wooden industry, upholstery, the building industry etc.) demand to timber resources; and then reduce the cutting of forest (timber), also just indirectly serve the effect protected forest resources.Therefore; in the various occasions that timber uses; adequately protect timber; increase the durability of timber; extend the service life of woodwork, as " throttling " measure solving China's timber resources deficiency, to protecting forest resources; realize the sustainable use of timber, there is great realistic meaning and strategic importance.
Particieboard is an important board kind in wood-based plate, compared with other plate kinds, its investment of production is relatively less, energy consumption is little, cost is low, not high to the requirement of material quality yet, as the raw material of particieboard, therefore can there be the advantage of its uniqueness in three surplus things, fast growing wood, recovery waste and old wood and some non-wooden materials in the Chinese development particieboard industry of timber resources scarcity.Particieboard its have the advantages that the natural timbers such as not yielding, surfacing, stable physical property do not possess, be widely used in the inside fitting and household appliance shell making etc. of Furniture manufacture, building, packaging, vehicle and boats and ships, also can make facing particieboard through secondary operations.But because particieboard is a kind of wood materials, easily by biological attack such as bacterium, worm, the raw boring in sea worms, easily rot, so the decay resistance of particieboard is not high, pest-resistant poor performance, makes it be subject to some restrictions in utilization.Therefore, in order to improve corrosion resistance and the insect resistance capacity of particieboard, extend the service life of particieboard, it is necessary for carrying out preservative treatment to particieboard.At present, the research of people to particieboard antiseptic property is attached great importance to, and how to manufacture the particieboard produced and have Anticorrosive Character and do not pollute environment, and extending the service life of particieboard, is the current urgent problems of people.
Summary of the invention
The object of this invention is to provide a kind of fire-resistant-chipboard with antiseptic property, and a kind of manufacture method of producing this anticorrosion particieboard is provided.
For realizing this purpose, the invention provides following technical scheme:
