Abstract
The invention discloses a wood material regeneration method, which comprises the following steps of: (1) swelling a tree branch; (2) peeling; and (3) binding and pressing. By the technical scheme, waste tree branches can be successfully regenerated and used; and a final product is non-toxic and has an extremely good mothproof effect.
Description
Technical field
The present invention relates to a kind of timber reuse method, belong to wood processing field.
Background technology
Since reform and opening-up, with the sustainable growth of economy and improving constantly of living standards of the people, urbanization paces are accelerated, and city capital construction is fast-developing, and tourist industry, decorative craft, upholstery, catering trade, exhibition industry are surging forward.Above factors. none does not form the powerful demand to timber and goods thereof.So month by month and year by year a large amount of timber pours in city endlessly.Synchronous therewith, producing a large amount of timber " rubbish " again towards the city of the fast race of target of modernization when every day is per.In fact, be this characteristic of resource of reusable edible from timber, it is obviously extremely inappropriate for being called rubbish.Say accurately. timber discards should be referred to as.Especially in the harvesting of wood and Urban Gardens eliminate always withered, sick, rotten and be not suitable with city cultivate a large amount of pruning brush woods.This kind of brush wood is little due to diameter, and adopt conventional decortication process peeling operation loaded down with trivial details, cost is high, and tend goes out of use, and causes the waste of a large amount of timber resources.
Summary of the invention
The present invention be directed to branch waste this phenomenon serious and carry out one and innovate technologies, adopt special technological means, not only can be good at utilizing discarded brush wood to regenerate timber, and regeneration timber also having the high characteristic of nontoxic quality.
For solving the problem, the present invention by the following technical solutions:
(1) branch swelling: be cut into the long section of about 0.5-1 rice by discarded, branch is placed in airtight container, adds the tincture of iodine, 0.4-2.0mpa, 80-120 DEG C, 1-3h, soaks 48-72 hour;
(2) peel: the branch after soaking is taken out, heated-air drying 2-4h, then the bark come off is separated with wooden by air blast;
(3) bond: adopt epoxy resin and rear abrasive dust to the 800 object fine powder of the synthesis such as mylar, curing agent, in tiling closed container, 45 DEG C time, pressure reaches 8-20mpa, by compressing for instantaneous high-temperature 180 DEG C of baking ovens after complete for binder powders penetrated wood, to obtain final product.
Pressure described in step (1) is preferably 0.8-1.6mpa; Preferred, 1.0-1.2mpa.
The preferred 40-80 DEG C of heated-air drying described in step (2); Preferred, the every 10min of baking temperature heightens 5 DEG C, until modulation 40-80 DEG C.Slow adjustment temperature can make the tincture of iodine in even lumber and moisture, and the effect that bark is peeled off is better.
Epoxy resin described in step (3) and mylar, curing agent weight ratio are 3-8:4-8:1-3; Described curing agent is preferably one or more in 2-ethyl-4-methylimidazole, dicyandiamide or HHPA.
After soaking, the tincture of iodine immerses in timber, and after HTHP, because timber is different with the coefficient of expansion of bark, bark and timber are loosened, and even part is peeled off.Timber after immersion is through heated-air drying, and the alcohol volatilization in timber, thoroughly peels off bark and timber after iodine heating sublimation.After bark is peeled off, timber is pulverized, after grinding to form wood powder, then add that namely resin agitating is even, compressing can realize object of the present invention.
Adopt technical scheme of the present invention, achieve the regeneration of discarded branch smoothly, final product is nontoxic, also has good mothproof effect simultaneously.
