Description
Technical field
The present invention relates to wood materials deep process technology field, particularly a kind of stalk adds fire-type high density fiberboard 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.
Summary of the invention
The object of this invention is to provide a kind of stalk and add fire-type high density fiberboard and preparation method thereof.First the present invention utilizes soaking with sodium hydroxide agricultural crop straw, the wax coat on stalk top layer can be reduced, make the stalk fibre that content of ashes is low, again stalk fibre and wood-fibred are mixed rear aluminium hydroxide, Firebrake ZB etc. to coordinate with silane coupler etc. and process, amalgamation, uniformity, the fire protection flame retarding of further raising composite fibre, the fiber like this after process and adhesive, waterproofing agent can be combined closely, not easily layering, steady quality is homogeneous, and intensity is high.
In order to realize object of the present invention, the present invention is by following scheme implementation:
