Description
Technical field
The present invention relates to wood materials deep process technology field, particularly anlistatig high density fiberboard of a kind of shock resistance and preparation method thereof.
Background technology
In recent years, the development of China middle and higher density fiberboard industry is very fast, hardboard originally progressively replace by medium and high density fibre panel.MDF enterprise is very large to the dependence of wood raw material, and wood raw material cost accounts for about 45% of production cost, the wood raw material production having badly influenced fiberboard in short supply.With regard to the requirement that medium and high density fibre panel is produced, be more than 10 years, the regeneration period of bamboo is also at 3-5, and the regeneration period of agricultural crop straw is 1 year or less than 1 year, from the utilization ratio of resource, the stalk of crops was the most favourable.China is large agricultural country, have abundant agricultural straw resource, but at present the utilization rate of China's stalk resource is only 33%, all the other most of stalks are fallen as castoff burning or only as fuel, not only cause the waste of natural resources, and weighting ring environment pollution.Adopt the cheap agronomic crop fibre strong with recyclability to replace wood raw material, become a direction of middle and higher density fiberboard development gradually.But the herbaceous plant fiber taking crops as representative is then short and thin, limits the mechanical strength of turf fibre plate to a certain extent.The content of herbaceous plant stem stalk organic solvent extract is obviously lower than wood raw material, but main component is wax, accompany by a small amount of higher fatty acids, higher alcohol etc., add that grass cane, epidermal leaf cells silicidize degree are very high, wax coat and the dioxide-containing silica on stalk surface are high, be unfavorable for the infiltration of adhesive, result in the gummed of traditional Lauxite to crushed straw aggregate bad.When this just requires to utilize the herbaceous plant fibers such as agricultural crop straw to manufacture high density fiberboard, the traditional adhesive existed in existing technique must be solved and glue together bad, poor water resistance, intensity difference defect.
It is formaldehyde series glue three kinds of Typical Representatives that phenolic resins, Lauxite and melamine resin adehsive stick agent, uses the most distinct issues of three-aldehyde glue to be free formaldehyde release.Three-aldehyde glue series wood-based plate constantly can discharge free formaldehyde, serious harm health in 3-15 before production and products thereof uses.Both at home and abroad the demand of the wood-based panel products such as no-formaldehyde density board is grown to even greater heights.Find in production practices, Aqueous Polyurethane Adhesives etc. do not arise at the historic moment containing the adhesive of formaldehyde, and occupation rate of market is more and more higher, but because price is higher, utilize it will inevitably bring the increase of the production cost of density fiber board as adhesive, but a part of composition can be saved under the prerequisite adopting the raw material such as agricultural crop straw, wood leftover material, so both can not cause the increase of cost, also the product of safety and environmental protection in producing, is worth commercially promoting.
Along with the development of high density fiberboard, be only the demand that intensity, resistance to water have not reached market development far away, this just requires the sheet material constantly developing various performance, to meet the demand in market.
Summary of the invention
The object of this invention is to provide anlistatig high density fiberboard of a kind of shock resistance and preparation method thereof.The present invention to process fiber by certain method is composite afterwards by adding stearine, PVC powder and silane coupler, and can improve the gumminess of fiber, intensity, impact resistance, antistatic, the product made has excellent performance.

(2) wood leftover material is sent in wood chipper be cut into irregular spile, under 155-165 DEG C of condition, with saturated vapor (pressure is 0.75MPa), boiling is carried out to wood chip, send in defibrator after wood chip is softening, at the same temperature, under the mixing speed effect of 1200-1400 rev/min, wear into wood-fibred, the crop branch fiber obtained with step (1) is mixed to get composite fibre;
(3) PVC powder, nano zinc powder, stearine and silane coupler kh450 are put into ball mill ball milling and after 30-40 minute, join the ethanol that concentration is 95%, stir under normal temperature after forming suspension and composite fibre is soaked wherein, pull out after 20-30 minute, put in an oven after drying, dry 30 minutes under the condition of 85-95 DEG C, take out the composite fibre obtaining surface modification after it cools naturally;
(4) mixed slurry is made after first Aqueous Polyurethane Adhesives and emulsified wax being stirred stand-by; The composite fibre of surface modification step (3) obtained adds the mixed slurry of half amount after mixing agitator is by fabric thrashing, stir, then the material after mixing thoroughly is sent in spray mixer, continue to spray into second half mixed slurry, obtain the composite fibre before hot pressing;
(5) composite fibre before hot pressing is mated formation equably in the slab meeting technological requirement, control the thickness of fiberboard, first precompressed on vulcanizing press, then through continuous rolling precompressed, obtain preformed slab, again preformed slab is sent into hot press and carry out that hot-forming (control hot pressing temperature is 180-210 DEG C, and briquetting pressure is 40kg/cm
2, the dwell time is 3-4 minute) namely obtain product of the present invention.
The invention has the beneficial effects as follows: the present invention adopts a large amount of agricultural crop straws and wood leftover material to substitute timber, a large amount of timber resources can be saved like this, by certain treatment process, extract fiber, novelty PVC powder, stearine, nano zinc powder etc. are processed by the composite rear fiber to mixing of certain mode with silane coupler, can the antistatic behaviour of fortifying fibre, gain in strength and impact resistance; Again the mixing such as Aqueous Polyurethane Adhesives, emulsified wax is carried out applying glue to the composite fibre after process at twice, blend glue stuff is evenly distributed between fiber and fiber and fiber surface, the product waterproof moisture-proof effect made after such process is remarkable, prevent fiberboard cracking, warpage, increase the service life.

(5) composite fibre before hot pressing is mated formation equably in the slab meeting technological requirement, control the thickness of fiberboard, first precompressed on vulcanizing press, then through continuous rolling precompressed, obtain preformed slab, again preformed slab is sent into hot press and carry out that hot-forming (control hot pressing temperature is 180-210 DEG C, and briquetting pressure is 40kg/cm
2, the dwell time is 3-4 minute) namely obtain product of the present invention.
