Description
Technical field
The invention mainly relates to the manufacture fields of particieboard, and in particular to the particieboard processing method of highly effective flame-retardant.
Background technology
Particieboard applies adhesive hot pressing by wood shavings and forms, and traditional product is mated formation assembly using surface layer sandwich layer grading structure,
High specific surface area, it is easy to process, paid attention to by the blueness of people.With scientific and technological progress, the derivative series of products of particieboard, deep processing
Kind emergence is simultaneously perfect, and types of functionality particieboard is gradually applied in national economy every field.
Particieboard production be unable to do without adhesive.Currently, urea-formaldehyde resin adhesive accounts for particieboard industry production glue total amount
90% or more, but the defect of Lauxite is not water-fast, has the free formaldehyde harm of remaining after making sheet.
Conventional wooden particieboard field is all to select isocyanates, phenolic resin, melamine resin cooperation organic
Fire retardant or composite fire retardant prepare function shaving board, and comprehensive without aldehyde, wood shavings fire-retardant, mould proof, moisture-proof function is integrated
Plate technology of preparing does not have document report mistake substantially.
Invention content
Invention broadly provides the particieboard processing methods of highly effective flame-retardant, to solve to propose in above-mentioned background technology
, the technical issues of a kind of particieboard integrating the multiple functions such as no aldehyde, fire-retardant, mildew resistant moistureproof is lacked on existing market.
The present invention solve the technical solution that uses of above-mentioned technical problem for：The particieboard processing method of highly effective flame-retardant, including：
Moso bamboo is mixed to get with miscellaneous bamboo and mixes bamboo chip, the miscellaneous bamboo includes any one of single bamboo, lubricum and fishscale bamboo or any two
The mass ratio of the combination or three kinds of combination of kind, moso bamboo and miscellaneous bamboo is 3：1；
Arbor is mixed to get with weedtree and mixes timber, the weedtree includes any one of shrub, rattan wood, pine or any two
The mass ratio of the combination or three kinds of combination of kind, arbor and weedtree is 3：1；
Cotton stalk and miscellaneous bar are mixed to get stalk, the miscellaneous bar includes in reed rod, maize straw and rape flower stalk
The mass ratio of a kind of or any two combination or three kinds of combination, cotton stalk and miscellaneous bar is 3：1；
By the obtained mixing bamboo chip, mixing timber and mixed straw, is chipped respectively, slicing, obtain wood shavings, will obtained
The wood shavings arrived are mixed by refueling machine, obtain mixing wood shavings；
Processing is dried to the mixing wood shavings, makes the moisture content of the mixing wood shavings within the scope of 5%-8%；
The wood shavings after drying process are sorted using secondary cyclone, are removed using water curtain process of cleaning or wet electrostatic
Dirt method removes the exhaust gas that bulky grain wood shavings are generated with sorting；
After separation is complete, fire retardant, reinforcing agent and flame-retarded resin are produced respectively, it is as follows：

It closes and is mixed evenly in liquid, then be down to room temperature, both obtain fire retardant；
According to 3 brown iron oxides：2 crushed crude pearlites：2 magnesium chloride powders：2 magnesia powders：1 sulfuric acid magnesium powder：1 sulfuric acid calcium powder：1 light calcium powder
It is added in closed ribbon mixer, stirs 20~50 minutes, both obtain reinforcing agent；
Successively by 10 ~ 20 parts of chloro styrene, 10 ~ 15 parts of maleic anhydride, 20 ~ 30 parts of tetrachlorophthalic anhydride, neopentyl glycol 40
~ 55 parts, 2 ~ 7 parts of methyl methacrylate, 8 ~ 15 parts of fiber, 6 ~ 10 parts of copper naphthenate, 1 ~ 3 part of cobalt iso-octoate, carbon
20 ~ 30 parts of sour calcium, 8 ~ 12 parts of silica are added into water, are warming up to 60~90 DEG C, react 1~3 hour logical cooling water
Cooling both obtains flame-retarded resin；
Wood shavings after drying process are mixed with fire retardant, reinforcing agent, wood shavings are mixed with fire retardant, reinforcing agent
Afterwards, flame-retarded resin mixing is added, the applied amount of fire retardant accounts for the mass percent 15% to 30% of the wood shavings after being dried, institute
The addition for stating reinforcing agent accounts for the quality percentage 20% to 45% of the wood shavings after being dried, and the addition of flame-retarded resin accounts for drying
The 20% to 40% of the mass percent of treated wood shavings；
Wood shavings are mated formation after being mixed with fire retardant, reinforcing agent, flame-retarded resin through mechanical spreading machine or air forming machine layering, are mated formation
It is molded afterwards by preformer, bamboo is formed through single layer interval guipure press or the compacting of multilayer interval press or continuous flat press after molding
The particieboard of base or the wooden base, described to be compressed to hot pressing, hot pressing temperature control in the hot pressing is at 100~150 DEG C, hot pressing
Period is 350~800 seconds, 1.0~3.0MPa of hot pressing unit surface pressure.
Preferably, described that the wood shavings after drying process are sorted using secondary cyclone, it is removed using water curtain
Dirt method or wet method electrostatic collector method removal bulky grain wood shavings and the exhaust gas of sorting generation include：It will using first order cyclone separator
Bulky grain wood shavings sedimentation separation in wood shavings is gone out, and using second level cyclone separator, to sub-argument, treated that wood shavings are further
Screening Treatment is further separated out larger particulate matter, then uses water curtain dedusting or the removal of efficient wet method electrostatic collector
The exhaust gas that grain object is generated with sorting.
Compared with prior art, beneficial effects of the present invention are：Reasonable design of the present invention, make difference, mainly pass through by
Moso bamboo and miscellaneous bamboo, arbor and weedtree, cotton stalk and miscellaneous bar blend, and are uniformly mixed, by adding fire retardant, reinforcing agent and resistance
Resin is fired, is a kind of completely new super plank to enhance fire-retardant, mould proof, the moisture-proof function of particieboard；
Meanwhile the invention solves the Form aldehyde release of traditional material by organic and inorganic material-modified wood shavings composite materials
Problem enhances wood materials, improves the water resistance and weather resistance of plank, it is excellent to assign entire particieboard
Fire protecting performance is a kind of novel all-round super plank；Also, the particieboard cost of the particieboard and traditional Lauxite compacting
Quite, there is high promotional value, product processes are simple, easily controllable, it can be achieved that industrialization.
Specific implementation mode
Incorporated by reference to following embodiment, detailed understanding is carried out to the present invention.
